Answer:
multiculturalism
Explanation:
What’s one example of a real-world problem which you might use knowledge from biological anthropology to help solve?
Answer:
Biological anthropology shows that cultural contexts are useful to explain human evolution.
Explanation:
Biological anthropology is a research area focused on the study of biological and behavioral determinants associated with human evolution. Biological anthropology enables us to trace the evolutionary origins of hominids and primates in general. Moreover, this discipline also sheds light on how different environments act on the mechanism of natural selection and thus shape human behavior. However, biological anthropology should not be considered to be part of social Darwinism used to apply Darwin's ideas to social policies.
Which is a disaccharide?
Answer:
Disaccharidases are glycoside hydrolases, enzymes that break down certain types of sugars called disaccharides into simpler sugars called monosaccharides. In the human body.
Explanation:
Disaccharide, also called double sugar, any substance that is composed of two molecules of simple sugars (monosaccharides) linked to each other. ... The three major disaccharides are sucrose, lactose, and maltose.
Three common disaccharides:
#sucrose — common table sugar = glucose + fructose.
#lactose — major sugar in milk = glucose + galactose.
#maltose — product of starch digestion = glucose + glucose.
A disaccharide is a sugar that can be created when two monosaccharides are linked together with glycosydic. Disaccharides are soluble in water and a few examples of this are; maltose, sucrose, and lactose. Finally, they’re also one of four chemical linkings for carbohydrates.

In the active site of the enzyme lotzase, a mutation of lysine 132 toaspartic acid causes a loss of lotzase function. Lotzase is most catalytically active at pH 7. Which is the following is the best reason why this might occur?
a. a negative charge is needed for substrate binding.
b. a positive charge is needed for substrate binding.
c. a general acid is needed for catalysis to occur.
d. more than one of the following can be a good reason.
Answer:
B. positive charge is needed for substrate binding
C. a general acid is needed for catalysis to occur
Explanation:
A mutation of lysine 132 toaspartic acid causes a loss of lotzase function as a result of the enzyme lotzase being most catalytically active at pH 7( neutral).
This condition is however achieved under conditions such as a positive charge being involved in the substrate binding and a general acid being involved in the catalytic process.

You have isolated a mutant of Shigella dysenteriae bacteria that is resistant to kanamycin, and you want to find out what gene is responsible. Design a protocol using genetic selection to identify it
Answer:
It is possible to identify the function of a gene by site-specific targeted mutagenesis (i.e., by using a reverse genetics approach).
Explanation:
Targeted mutagenesis is an approach widely used in molecular biology in order to determine the functions of endogenous genes. Targeted mutagenesis is a type of genetic technique known as reverse genetics since it is a technology that enables to identify the function of a gene by modifying its product (i.e., its corresponding messenger RNA), thereby synthesizing non-functional proteins.
Moreover, it is also possible to identify the function of a gene by altering its expression, for example, by using small interfering RNAs (siRNAs) that inhibit protein translation through RNA interference (RNAi) mechanisms.
A rat population has an average weight gain between weeks 2 and 4 of 10 grams, and the narrow-sense heritability of the weight gain between 2 and 4 weeks is 25%. What average weight gain would be expected among the offspring of parents whose average gain was 15 grams?
Answer:
The correct answer is - 11.25
Explanation:
Given:
Average weight gain between weeks 2 and 4 = 10 grams
The narrow-sense heritability of the weight gain between 2 and 4 weeks
= 25%
Then
Average weight gain would be expected among the offspring of parents whose average gain was 15 grams-
by the formula:
Average weight gain between weeks + (h) (Average weight gain between weeks - parents average gain )
= 10 + 0.25 (15-10)
= 10 + 0.25 (5)
= 10 + 1.25
= 11.25
Thus, the correct answer is - 11.25

explain why all the offspring in the F1 generation were yellow instead of half being yellow and half green, or some other mix of the colors. Hint: Remember that Mendel coined the terms dominant and recessive.
Answer:
Yellow is a dominant trait.
Explanation:
There are dominant alleles and recessive ones. Say Y is a dominant allele and y is a recessive one. YY makes yellow, Yy makes yellow, and yy makes green. It takes just one dominant allele to make a phenotype (physical traits) express it. Look at the photo to help guide you. Using a punnet square you can find that both parents give a dominant allele and it only takes one.

Which of the following would you use to inhibit the contraction of muscle in vitro as a control for an experiment you are conducting?
A. a motor protein ATPase inhibitor
B. a drug that increases T-tubule depolarization
C. a drug that increases sarcoplasm Ca2+ concentration
D. a Ca2+-ATPase inhibitor
E. All would inhibit muscle contraction.
Answer:
The correct answer is option A. a motor protein ATPase inhibitor.
Explanation:
Motor proteins are sub-atomic motors that utilize ATP hydrolysis to move along cytoskeletal filaments inside the cell. They satisfy numerous capacities inside the biological system, controlling the sliding of filaments for muscle contraction and intervening intracellular movement along biopolymer filament tracks.
The two globular head motor areas in heavy chains can change over the chemical energy of ATP hydrolysis into mechanical work to move along microtubules.
Thus, in vitro experiment inhibitor of the motor protein, ATPase will be a control.
Earth is comprised of four systems, or spheres. Give one example of how a change in one of these spheres of the Earth can affect one or more of the other spheres.
Answer:
Earth is comprised of four circles: the lithosphere, hydrosphere, atmosphere, and biosphere. Changes in any piece of the Earth's framework influences every single other circle.
For example, storms structure in the air which bring precipitation and leads to the rain. Rain influences the hydrosphere by expanding the measure of water in a river, which influence the progression or flow of the stream. flowing rivers change the outside of the lithosphere. Plants and creatures in the biosphere rely upon water to endure.

A cell has a defect in its receptor for growth factors, preventing growth factors from attaching to and signalling the cell. Based on this, which prediction below is most likely?
A. The cell will remain dormant in GO phase.
B. The cell will grow uncontrollably and continue to divide as long as it has food.
C. The cell will replicate its DNA but be unable to begin mitosis.
D. The cell will begin DNA replication but will be unable to complete S phase.
Answer:
Option B
Explanation:
B. The cell will grow uncontrollably and continue to divide as long as it has food.
Cell growth is theeoretically stimulated by the binding of growth factors to their receptors using signaling pathways.
These pathways are regulated by proteins which are encoded for in the genes.
The gene that controls the regulation of these pathway when mutated produce malfunctioning signaling protein thus not allow for regulations of the cell cycle causing uncontrollable cell division. These mutated genes are called oncogenes.

The lock-and-key mechanism refers to a) the complementary shapes of an enzyme and a substrate. b) the attractive forces between an enzyme and a substrate. c) the ability of an enzyme to lower the activation energy of a reaction. d) the ability of an enzyme to “unlock” the products of a reaction.
Answer:
A. The complementary shapes of an enzyme and a substrate
Explanation:
The Lock-and-Key model was made to show how an enzyme's active zone fits a substrate and how they bond together. It correlates just like a lock and a key; you have to have the correct-shaped key in order to open a lock. Same process of thought with the enzymes; you must have the same shape for both in order to bind together,

What is nutrient cycling?Nutrient cycling is the process by which nutrients are transformed, transported, and exchanged between different parts of an ecosystem. Nutrients are essential for the growth and survival of all living organisms, and they are constantly being recycled through various processes in the environment.
For example, plants absorb nutrients from the soil and water, and then animals consume these plants and incorporate the nutrients into their own bodies. When animals die, their bodies decompose, releasing the nutrients back into the soil or water, where they can be taken up by plants again. This continuous flow of nutrients between living organisms and the environment is known as nutrient cycling.
Nutrient cycling is important because it helps to maintain the balance of nutrients in an ecosystem and supports the functioning of the ecosystem as a whole. It is influenced by many factors, including geological processes, weather patterns, and the actions of living organisms.

A certain red-flowered plant is self-fertilized. The progeny are 131 white-flowered plants and 169 red-flowered plants. Give a genetic explanation for these observations.
Answer:
Ratio of red flowers: white flowers = 169: 131 = 9: 7 as given in the question. It is clear that the color is possible only by at least 2 genes.
Let assume genes are A and B.
Now the cross AaBb (Red) x AaBb (Red)
Gametes ----------> AB Ab aB ab AB Ab aB ab
AB Ab aB ab
AB AABB (Red) AABb (Red) AaBB (Red) AaBb (Red)
Ab AABb (Red) AAbb (White) AaBb (Red) Aabb (White)
aB AaBB (Red) AaBb (Red) aaBB (White) aaBb (White)
ab AaBb (Red) Aabb (White) aaBb (White) aabb (White)
The ratio of Red flowers: White flowers is 9:7
The red color flower is produced when both the alleles of genes are dominant. if any of the alleles of genes is recessive, it will produce the white color flower. This is one of example complementary gene interaction where the presence of both genes in the dominant form complements each other to produce red color flowers.

Which of the following is the muscle action that results in exhalation and causes the air pressure inside the lungs to be higher than outside the chest cavity?
a) Contraction of internal intercostals
b) Relaxation of the diaphragm
c) Contraction of the diaphragm
d) Relaxation of the external intercostals
Answer:
the correct option is: b) Relaxation of the diaphragm
Explanation:
During exhalation or exhalation ALL the muscles of the thorax cavities relax, unless it is a forced expiration there they will not be relaxed, but this is a voluntary and infrequent process.
The relaxation of the diaphragm is what generates an increase in intrapulmonary pressure and therefore it is forced to release its pressure by releasing air through the respiratory tube.
Although it is also valid to say that the internal intercostals are relaxed, since it is true! And it would also be considered as correct, but the diaphragm being a muscle of greater size and greater power generates a more significant effect on the exhalation, that is why it was decided to choose that as the correct option.
Answer:
Relaxation of the diaphragm
