The options are missing in this question; here are the options:
According to E. Mavis Hetherington's research, Barney would most likely be categorized as a(n)
A) defeated
B) competent loner
C) enhancer
D) good-enough
The answer to this question is A) defeated
Explanation:
E. Mavis Hetherington is an important Canadian psychologist mainly known for studying divorce and the effects of it. About this, the psychologist proposed divorce is a complex process and has a great impact on those involved. In the case of the spouses, E. Mavis Hetherington proposes four main styles spouses might acquire after divorces such as competent loner, defeated, enhancer, etc.
In the category of defeated this psychologist includes those that do not cope with life after divorce, instead, they experience depression, loneliness, regrets, and other negative feelings, which stop them from thinking positively about the future or adapting to their situation. This category describes Barney because after divorce he feels regretful and depressed; also, he has great difficulty to cope with life or adapt to the situation.
Please explain study of variation patterns in different taxon.
Answer:
By using genetical and ecological approaches
Explanation:
Genetic variation is useful to study the diversity of the species and to understand both intraspecific and interspecific variation patterns. In genetics assays, two or more genetic sequences belonging to different organisms are compared in order to determine nucleotide differences (i.e., homology level) between the complete sequences, which enable to determine the evolutionary relationships between taxa.
Ecological diversity is associated with the variation of terrestrial and aquatic ecosystems. Ecological variation across species can be represented by different measures such as niche variation among individuals, the number of trophic levels, etc. Ecological variation patterns may affect the ecological dynamics of species and their communities, thereby being of vital importance for diversity classification studies.
Explain why Inuit Eskimos, despite living in polar regions with little sunlight, remain
dark-skinned like their equatorial ancestors.
Answer:
Due to genetics.
Explanation:
Inuit Eskimos, remain dark-skinned like their equatorial ancestors despite living in polar regions with little sunlight because this black color transfer from generation to generation through genetics. These Inuit Eskimos are descendants of black people that were lived in the equatorial regions of the earth so these Inuit Eskimos also has black skinned like their ancestor.
The spread of cancer cells from one site to others in the body is known as _____.
Answer:
metastasis
Explanation:
Metastasis is the process in which cancer cells break away from the place where they first formed and travel through the bloodstream to other parts of the body where they form a new tumor.
Hope that helps.
Some organisms are made of single cells and live in the hot acidic environment of deep ocean vents.
Some organisms are single cells and live one the surface of your skin.
And there are small multicellular organisms that make fuzzy circular growth on old bread.
And of course, roses with pretty flowers are organisms.
And whales.
That’s a lot of diversity. So let’s say I think those creatures are just so different that they just couldn’t ALL be related to each other. Using specific traits, convince me that all of these organisms can be traced back to a common ancestor. (At least 6 well-chosen traits required for full credit.)
Write your answer in the essay space.
Answer:
All organisms are composed of cells that share a structural organization and play roles in similar biological processes.
Explanation:
All living organisms can be grouped in terms of cellular organization, functioning, and structure. These features enable us to define them as “subjects” of life. Organisms share basic biological mechanisms such as, among others, growth, homeostasis, development, energy processing, reproduction, etc. Moreover, life is also defined by the presence of essential biomolecules such as DNA, RNA, proteins and lipids. Finally, the cell is considered to be the basic unit of every life form, and organisms may be formed by one (unicellular) or more cells (multicellular). The fundamental feature of the cell is the presence of a membrane that separates it from the external environment, thereby defining its internal environment.

Asthma is a restrictive lung disorder that causes constriction and congestion of the pulmonary bronchioles. How would an asthma attack affect FVC?
Answer:
Explanation:
This includes a decrease in the rate of maximal expiratory air flow (a decrease in FEV1 and the FEV1/FVC ratio) due to the increased resistance, and a reduction in forced vital capacity (FVC) correlating with the level of hyperinflation of the lungs.
help asap giving branlist plsss helppp
Answer:
except option 2 all of them are applied
Explanation:
Use the following information to answer the question below.
Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all F1 individuals have red, axial flowers. The genes for flower colour and location assort independently.
If 1000 F2 offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers?
Answer:
750
Explanation:
With the f1 generation all being red flowers we can conclude that Red is dominant (R) and white is recessive (r).
This leads to the f1 generation having Rr. If you breed two Rr together you get
1 RR
2 Rr
1 rr
75% of the f2 will have red flowers. So if you take 1000 and multiply it by .75 you will get 750
Approximately 750 flowers will be Red.
compare the innate and adaptive responses to repeated challenge with the same antigen by sketching the immune response curve over time
Answer:
Innate immunity is defined as the first line of defense against infections and faster than adaptive immunity while adaptive immunity is second or third line of defense mediated by the T and B lymphocytes.
Adaptive immunity forms memory cells for the same antigen while innate immunity do not.
As shown in the graph below, when an antigen enter in the body for the first time, our immune system response with innate immunity and response immediately with several symptoms such as sneezing, swelling or redness et-cetra. Then after few days adaptive immunity forms which is mediated by the T and B lymphocytes by forming against the antigen.
Now if the body exposed to the same antigen again (Secondary exposure), the immune system shows amplified response as it has already formed memory cells against the antigen.
Alternative to glucose based cellular respiration
Answer:
Cellular respiration is defined as a metabolic reaction occurs in cells, in which chemical energy from glucose is converted into adenosine triphosphate (ATP).
The alternative to glucose based cellular respiration is fermentation in which energy is produced from the oxidation of organic compounds, such as glucose from within a cell as "electron acceptors".
is lactase exergonic
Answer:
The correct answer is - yes lactase action is exergonic.
Explanation:
Lactase is an enzyme located in the small intestine of mammals including humans, however it is produced by many organisms in their body. Lactase is an essential enzyme as it helps in the digestion of the whole milk by breaking down the lactose, sugar present in milk.
Exergonic reactions are the reaction that releases energy by the breaking of molecules in any reaction. Generally, catabolic reactions are exergonic lie lactase catabolizes the lactose present in milk and release energy.
Thus, the correct answer is - yes lactase action is exergonic.

Explanation:
The nerve cells in your body must constantly remove substances from the cell against the concentration gradient. What type of process most likely takes place to remove substances from a cell against the concentration gradient? Explain.
Answer and explanation:
Active transport refers to a procedure, which withdraws substances from a cell against the concentration gradient. During the process, the molecules move from low concentration to a high concentration.
The mechanisms of active transport need the application of the energy of the cell, generally in the form of ATP. If a substance needs to move within the cell against its concentration gradient, that is, if the substance's concentration within the cell is more than its concentration in the extracellular fluid, then the cell must utilize energy to move the substance.

The cross AB/ab X ab/ab produces the following progeny: AB/ab 391, ab/ab 401, aB/ab 406, Ab/ab 386. From these data, one can conclude that the A and B loci assort independently.
A. True
B. False
Answer:
B
Explanation:
The two loci did not assort independently.
In order to check for independent assortment or otherwise of the result from the cross, Chi-square is used to see if the result conforms with that of Mendelian standard of 9:3:3:1.
Phenotype Observed f Expected f [tex]X^2[/tex] = [tex]\frac{(O - E)^2}{E}[/tex]
AB/ab 391 9/16 x 1584 = 891 [tex]\frac{(391-891)^2}{891}[/tex] = 280.58
ab/ab 401 3/16 x 1584 = 297 [tex]\frac{(401-297)^2}{297}[/tex] = 36.42
aB/ab 406 3/16 x 1584 = 297 [tex]\frac{(406-297)^2}{297}[/tex] = 40.00
Ab/ab 386 1/16 x 1584 = 99 [tex]\frac{(386-99)^2}{99}[/tex] = 832.01
Total [tex]X^2[/tex] = 280.58 + 36.42 + 40.00 + 832.01 = 1,189.01
Degree of freedom = 4 - 1 = 3
Tabulated [tex]X^2[/tex] at degree 3 freedom and 95% level = 7.815
The calculated [tex]X^2[/tex] value is more than the tabulated value. Therefore, we conclude that the outcome of the cross is not in agreement with Mendelian standard and hence, the A and B loci did not assort independently.
The correct option is B.

processes involved when an eye views an object
Answer:
cornea
Explanation:
When light rays reflect off an object and enter the eyes through the cornea (the transparent outer covering of the eye), you can then see that object. The cornea bends, or refracts, the rays that pass through the round hole of the pupil.
What are the five senses? Type your brainstorm
Answer:
Sense: Smell, Taste, Touch, Sight, Hearing
Explanation:
Answer:
touch, sight, hearing, smell, taste
Explanation:
Touch is thought to be the first sense that humans develop, according to the Stanford Encyclopedia of Philosophy. Touch consists of several distinct sensations communicated to the brain through specialized neurons in the skin. Pressure, temperature, light touch, vibration, pain and other sensations are all part of the touch sense and are all attributed to different receptors in the skin.
Sight, or perceiving things through the eyes, is a complex process. First, light reflects off an object to the eye. The transparent outer layer of the eye called the cornea bends the light that passes through the hole of the pupil. The iris (which is the colored part of the eye) works like the shutter of a camera, retracting to shut out light or opening wider to let in more light.
hearing sense works via the complex labyrinth that is the human ear. Sound is funneled through the external ear and piped into the external auditory canal. Then, sound waves reach the tympanic membrane, or eardrum. This is a thin sheet of connective tissue that vibrates when sound waves strike it.
Humans may be able to smell over 1 trillion scents, according to researchers. They do this with the olfactory cleft, which is found on the roof of the nasal cavity, next to the "smelling" part of the brain, the olfactory bulb and fossa.
The gustatory sense is usually broken down into the perception of four different tastes: salty, sweet, sour and bitter. There is also a fifth taste, defined as umami or savory. There may be many other flavors that have not yet been discovered. Also, spicy is not a taste.
Classify the following organisms into their respective kingdoms
1)Yeast
2)Penicillium
3)Rhizobium
4)mushroom
5)Amoeba
6)fish
Answer:
Yeast - Fungi Penicillium - Fungi Rhizobium - Monera mushroom - Fungi Amoeba - Protozoan fish - AnimaliaExplanation:
The Fungi Kingdom is a kingdom composed, as the name says, of fungi, which are organisms represented by many species, among them: yeasts, mushrooms, molds, Penicillium and others. As you already know, fungi are eukaryotic and multicellular organisms (with the exception of yeasts).
The monera kingdom is the kingdom formed by bacteria and also has several species as members. Among these species we can mention the Lactobacilli, Escherichia coli, Rhizobium (nitrogen-nodulating bacteria, very important for the natural fixation of nitrogen in legumes), among others.
The kingdom of protozoa is very diverse and even has an organism that does not have any type of genetic, structural and morphological similarity, but in most cases, the members of this kingdom are heterotrophs, eukaryotic and unicellular organisms. An example of this is amoebas.
The animal kingdom is made up of all animals, the most diverse and populous kingdom. All animals belong to that kingdom, including fish.

◉ They have a thinner atmosphere. Correct!
◎ Both are closer to the sun than Venus.
◎ Their masses are lower.
Explanation:
Venus has a very dense atmosphere compared to Mars and Mercury. This causes many small meteorites and asteroids to break apart before they reach the surface. Thus, Venus has fewer craters than Mars and Mercury.
Which could best be used to explain why bacteria can infect a person very quickly? outer capsule binary fission protective covering genetic recombination
The reason why bacteria can infect a person very quickly is because of the process of binary fission.
What is binary fission?
Binary fission is defined as the reproduction process that is found in prokayotes such as the bacteria.
The binary fission involves these steps:
Replication of DNA (deoxyribonucleic acid),Growth of a cell,Segregation of DNA and Splitting of cells.The final stage which is the splitting of cells leads to the formation of many daughter cells of the parent bacteria cell which can eventually led to infection.

Coal and petroleum products (fossil fuels) are a powerful resource of ___________ and energy. Following _________ plants and animals are buried and "stored" underground for millions of years leading to the formation of these byproducts.
Answer:
Carbon AND
DEATH
Explanation:
Carbon containing organic molecules derived from the remains of dead plants and animals on the earth million of years ago, buried deep under the sediment and rock layers are called Fossil fuels. Coal,oil,and natural gas are examples.
These underground deposits were formed million of years ago,due to the chemical reactions between relatively underground water molecules on one hand,and the earliest mic organisms viz algae,bacteria which inhabited the earth other hand.These decomposition occurred around 540 to 65milion years ago.
However,some million of later chemical reactions in the soil leads to compression of these remains underground.The degradation leads to formation of the fossil fuel precursor called Kerogen. With time Geothermal heat transforms the kerogen precursor to fossil fuel. some other kerogens are transformed to other natural gas,coal etc.
If a shallow pan is filled with water, a drop of red ink is placed in one end of the pan, and a drop of green ink is placed in the other end, which of the following will be true at equilibrium?
a. The red ink will be uniformly distributed in one half of the pan, and the green ink will be uniformly distributed in the other half of the pan.
b. The red and green inks will be uniformly distributed throughout the pan.
c. Each ink will move down its concentration gradient.
d. The concentration of each ink will be higher at one end of the pan than at the other end.
e. No predictions can be made without knowing the molecular weights of the pigment molecules.
Answer:
b. The red and green inks will be uniformly distributed throughout the pan.
Explanation:
The inks distribute throughout the particles of water. It does not matter that one drop of ink was placed in one end, and the other on the other end. The constant movement and collision of particles make the ink's drop distribute uniformly in the pan. Besides, there will we a tendency to have the same amount of ink concentration in all the pan; to this, they have to distribute evenly.
