Answer:
1. Picky eating; food jag
2. epiphyseal plates
3. bone mineral density (BMD)
4. obesity
5. food insecurity
6. life expectancy
7. arthritis
8. congregate meal
Explanation:
Picky eating is a behavior in early childhood when they refuse to eat certain foods and only want the same foods, while food jag is when a child only eats a small group of foods, meal after meal. The epiphyseal plate is a specialized layer of hyaline cartilage where chondrocytes (i.e., the only cells found in healthy cartilage) proliferate and differentiate during longitudinal bone growth. Arthritis is an inflammation of the joints caused by different reasons (e.g., injury, genetic causes, infections, immune system dysfunction, etc), whose risk increases with age. Bone mineral density (also known as bone density), is the amount of mineral in bone tissues, being the best manner to measure bone health. Obesity can be defined as an excessive amount of body fat that presents a risk to health. Over the past 30 years, the prevalence of obesity has doubled in children and tripled in adolescents, representing a serious health problem (especially in developed countries). Moreover, food insecurity is a social condition of limited access to food for individuals in a household to live an active, healthy life, which can be used as a metric of how many people cannot afford food. Life expectancy is an estimation of the number of years a person can expect to live in a given country/region. Life expectancy around the world has increased for nearly 200 years especially due to medical progress and access to food. Finally, a congregate meal refers to a healthy meal provided to anyone age 60 or over that encourages older adults' social connections with other persons at the meal sites.

Assume similar data for the motion of the blood in a carotid artery which connects the aorta to the brain. Estimate how many beats of the heart it will it take the blood to get from your aorta to your brain. (Assume that the distance from your aorta to your brain is 30 cm.)
Answer:
4 beats
Explanation:
The number of beats of the heart that will take blood from Aorta to The Brain
n = Distance from Aorta to brain / distance per beat
Given that distance per beat = 7.5 cm ( calculated value outside scope of question using the data attached below)
n = 30 cm / 7.5 cm
= 4 beats
Hyperglycemia (elevated blood sugar levels), such as would happen in diabetics, can damage the glomeruli.
a. True
b. False
Answer:
True
Explanation:
Hyperglycemia which means high Glucose level in the blood as a result of lack of insulin can damage the glomeruli. This interfere with the function of the glomeruli. Normally glomeruli fiters blood and remove nutrients to form urine but hyperglycemia will affect it's negatively and will make protein to leak from the blood into the urine. This can also lead to glomeruli called glomerulosclerosis.
In addition to the transmission electron microscope (TEM), there is another type of electron microscope that is frequently used for specific purposes when studying cells and tissues, and even whole organisms. This microscope is called a scanning electron microscope (SEM). Use your lab manual, its support resources, and/or the Internet to investigate the use of scanning electron microscopy for biological applications. After gathering this information, please answer the following question. When would it be appropriate to use the SEM rather than the TEM
Answer:
The basic difference between SEM and TEM is that TEM generates an image with the assistance of radiation that goes through the specimen, while the images generated by the SEM take place with the assistance of electrons getting released from the surface of the specimen.
SEM is primarily used to examine the composition of the surface, with the help of SEM one can study the microbes present in the ecological niche like in the lining of the gut and human skin. Due to its great depth, it is considered the electron microscope analog of a stereo light microscope. It helps in providing complete images of the cells present on the surface, which are not easy to get with the help of TEM. Due to its enhanced functionality, it can also be used for size determination and particle counting, and also for process control.
A behavior with both innate and learned components that is irreversible and is triggered during a sensitive period.
Fixed action pattern
Imprinting
Operant conditioning
Migration
Answer:
The correct answer is - Imprinting.
Explanation:
Imprinting is a behavior that includes both innate components and learning components and normally can not be irreversible. It is something that takes place at a specific sensitive period.
For instance, ducklings follow their mother is imprinting that is both innate and learned at a limited phase after birth during development. It can be visual or auditory or other ways that an animal can develop imprinting.
Rheumatoid arthritis is commonly associated with the presence of rheumatoid factor autoantibodies in the bloodstream. This indicates that rheumatoid arthritis is likely to be a. an infective process. b. caused by bacterial infection. c. an autoimmune process. d. because of an enzymatic defect.
Answer:
The correct answer is - c. an autoimmune process
Explanation:
Rheumatoid arthritis is a disease or condition that affects the joints mainly by swollen, and painful joints. It is an autoimmune disease as the person's own immune system attacks the body.
The presence of rheumatoid factor autoantibodies states that it is an autoimmune process. There are other autoantibodies also associated with this type of arthritis that are rheumatoid factors (RF), anti‐keratin antibodies (AKA), anti‐filaggrin antibodies (AFA), and anti‐perinuclear factor (APF).
The R and S loci are 35 m.u. apart. If a plant of genotype is selfed, what progeny phenotypes will be seen and in what proportions
Complete question:
The R and S loci are 35 m.u. apart. If a plant of genotype RS/rs is selfed, what progeny phenotypes will be seen and in what proportions
Answer:
R-/S- = 0.6052 R-/ss = 0.1443rr/S- = 0.1443rr/ss = 0.1056Explanation:
Available data:
R-S are 35 mu apartCross: RS/rs x RS/rsFirst, we need to recognize the parental gametes and the recombinant ones.
Cross:
Parentals) RS/rs x RS/rs
Gametes) RS Parental ⇒ Equal to the parental genotype
rs Parental ⇒ Equal to the parental genotype
Rs Recombinant ⇒ Product of recombination
rS Recombinant ⇒ Product of recombination
We know that genes are 35 MU apart from each other. The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.
To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
According to this information, if 1 MU = 1% recombination frequency, then
35MU --------- 35% recombination frequency = 0.35
Now, let us calculate the frequency of each gamete type.
35 map units = 35 % of recombination in total
= % Rs + % rS
= 17.5% Rs + 17.5% rS
Now, if the recombination frequency equals 35% then the parental frequency is 100% - 35% = 65%
65 % parental frequency = % of RS + % rs
= 32.5% RS + 32.5% rs
The frequency of each gamete is
RS ⇒ Parental ⇒ 32.5% (65% / 2) = 0.325rs ⇒ Parental ⇒ 32.5% (65% / 2) = 0.325Rs ⇒ Recombinant ⇒ 17.5% (35% / 2) = 0.175rS ⇒ Recombinant ⇒ 17.5% (35% / 2) = 0.175F1 Genotypes and Proportions
RS/RS = 0.325 x 0.325 = 0.1056 RS/Rs = 2x 0.325 x 0.175 = 0.1137RS/rS = 2x 0.325 x 0.175 =0.1137 rs/rs = 0.325 x 0.325 = 0.10562rs/RS = 2x 0.325 x 0.325 = 0.2112rs/Rs = 2x 0.325 x 0.175 = 0.1137rs/rS = 2x 0.325 x 0.175 = 0.1137Rs/rS = 2x 0.175 x 0.175 = 0.061Rs/Rs = 0.175 x 0.175 = 0.0306rS/rS = 0.175 x 0.175 = 0.0306F1 Phenotypes and Proportions
R-/S- = 0.1056 + 0.1137 + 0.1137 + 0.2112 + 0.061 = 0.6052 R-/ss = 0.1137 + 0.0306 = 0.1443rr/S- = 0.1137 + 0.0306 = 0.1443rr/ss = 0.1056
If R and S loci are 35 m.u. apart and a plant of genotype RS/rs is selfed, then the progeny phenotypes will be 0.606 RS; 0.106 rs; 0.144 Rs and 0.144 rS.
In this case, it is imperative to estimate gamete frequencies
RS = 0.65% / 2 = 0.325rs = 0.65% / 2 = 0.325Rs (recombinant) = 0.35 / 2 = 0.175rS (recombinant) = 0.35 / 2 = 0.175In consequence, the F1 genotypes will be RS/RS = 0.1056 (i.e., 0.325 x 0.325); RS/Rs = 0.1137; RS/rS = 0.1137; rs/rs = 0.10562; rs/RS = 0.2112; rs/Rs = 0.1137; rs/rS = 0.1137; Rs/rS = 0.06; Rs/Rs = 0.0306; and rS/rS = 0.0306.Finally, it is possible to obtain phenotypic frequencies by summing genotypic frequencies for each case in particular.In conclusion, if R and S loci are 35 m.u. apart and a plant of genotype RS/rs is selfed, then the progeny phenotypes will be 0.606 RS; 0.106 rs; 0.144 Rs and 0.144 rS.

Explanation:
What is the mechanism by which binding of testosterone to the testosterone receptor leads to upregulated gene transcription
Answer:
This binding causes a conformational change in the receptor which enters into the nucleus and binds DNA to activate transcription
Explanation:
Testosterone is a steroid hormone responsible for inducing protein synthesis and growth of tissues with androgen receptors. Testosterone receptors, also known as androgen receptors, are a class of nuclear receptors activated by binding androgenic hormones (e.g. testosterone) in the cytoplasm, whose binding induces a conformational change of the receptors that are subsequently translocated to the nucleus. Within the cell nucleus, these activated receptors form homodimers that bind DNA in order to promote the transcription of target genes capable of regulating cell growth, cell cycle progression and survival.
Generally, coral reefs are found in shallow waters between ______ degrees N latitude and ______ degrees S latitude.
Answer:
30 degrees;
30 degrees
Explanation:
Coral reefs are formed when the skeleton of the corals merge and combine with each other. The formation of coral reefs takes many years . Corals are the organism living in the ocean. They live in dense colonies and clusters. Coral reefs provides an ecosystem for other marine organisms to live in. The species live in the coral reefs and maintain their population. Corals live in the region of the ocean that has warm water and between the latitudes of 30 degrees North and 30 degrees South.
The antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline, chloramphenicol disk. Interpret the result.
Answer:
See Explanation
Explanation:
We define antibiotic susceptibility testing as an evaluation of the ability of antibiotics to inhibit bacterial growth. This test is necessary because certain bacteria may have developed resistance to certain antibiotics.
Hence, if the antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline and chloramphenicol disk, then it implies that these antibiotics are all largely effective against Staphylococcus aureus and could be used for treatment of Staphylococcus aureus infection.

Ecologists are interested in quantifying different kinds of biodiversity. In below study outlined here, which kind of biodiversity are ecologists studying?
Ecologists establish 20 small areas, called plots, randomly scattered across a California grassland. They count the number of different plant species present in each plot. By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland.
a. Genetic diversity
b. Functional diversity
c. Ecosystem diversity
d. Species diversity
Answer:
d. Species diversity
Explanation:
The species diversity can be measured by:
Species richness: Refers to the number of species are inhabiting a defined area. Species abundance: Describe the distribution of the species abundance.Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region or any well-defined spatial unit. It is a metric for measuring biodiversity which simplicity and easy interpretation make it a standard metric. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.

• Write the biofuel and biogas chemical formulas. Explain why biofuel and biogas are still considered energy-dense molecules. Compare the chemical makeup of each component to carbon dioxide, which is produced when glucose is completely oxidised.
Answer:
diesel fuel is C12H23 whereas Methane is CH4.
Explanation:
The chemical formula for common diesel fuel is C12H23 while o the other hand, the formal of biogas such as Methane which is CH4. Both are organic compounds due to the presence of hydrogen and carbon. Biofuel and biogas are still considered energy-dense molecules because they have more mass and produced large amount of energy from it. The main difference between Carbondioxide gas and biofuel is that there is no hydrogen present in the formula of carbondioxide gas.
Alleles are described as ____________________. homologous chromosomes homologous chromosomes alternate versions of a gene alternate versions of a gene alternate phenotypes alternate phenotypes environmental factors that affect gene expression
Answer:
The correct answer is - alternate versions of a gene.
Explanation:
In a cell, if there are two copies of each chromosome, these are called homologous chromosomes, one come from the father and the other comes from the mother, which helps in promoting the variety and stability of a species.
Different or alternate versions of genes are possible that can result in two phenotypes for the same trait, these alternate versions called alleles. Alleles can be dominant and recessive.
