76. Which of the following lipids are stored below the dermis of homeotherms? A. Lipids made up of unsaturated fatty acids. B. Lipids that are made up of unsaturated fatty acid. C. Lipids that are made up of cholesterol. D. None fatty acids?
Answers
The correct option is:
C. Lipids that are made up of cholesterol.
The lipids stored below the dermis of homeotherms are primarily triglycerides composed of saturated fatty acids and cholesterol esters. These lipids act as an insulating layer and energy store for the animal.
Options A, B and D are incorrect:
A. Lipids made up of unsaturated fatty acids. - Triglycerides with unsaturated fatty acids are not primarily stored below the dermis.
B. Lipids that are made up of unsaturated fatty acid. - Same as A, triglycerides with unsaturated fatty acids are not the main lipids stored below the dermis.
D. None fatty acids? - This does not make sense. Lipids stored below the dermis do contain fatty acids.
So the key point is that cholesterol esters, containing cholesterol, are the lipids primarily stored below the dermis of homeotherms.

how many moles of C atoms do you have if you have 1.23 x 10^24 atoms ?
Answers
Answer:
2.04 moles of C atoms
Explanation:
The number of moles of C atoms can be calculated using Avogadro's number, which is approximately 6.02 x 10^23 atoms per mole.
To find the number of moles of C atoms in 1.23 x 10^24 atoms, we need to divide the number of atoms by Avogadro's number:1.23 x 10^24 atoms / 6.02 x 10^23 atoms/mole = 2.04 moles
Therefore, if you have 1.23 x 10^24 atoms of C, you would have 2.04 moles of C atoms.

The standard Mendelian ratio for a dihybrid cross, in which the alleles of two distinct genes assort independently into gametes, is 9:3:3:1.
Is AA or AA homozygous?The alleles in the pair, whether they are both dominant or both recessive, are the same, so the term "homozygous" is used to characterize the pairs "AA" and "aa." The allelic pair "Aa" is referred to as heterozygous, in contrast.
What else is meant by homozygous?In terms of genetics, being homozygous means that you have inherited the identical alleles of a particular genomic marker from both of your biological parents. As a result, a person who possesses two identical copies of a genetic marker is said to be homozygous.

During the light reactions, ATP is produced by chemiosmosis through an electron transport chain, true or false?
Answers
The given statement "During the light reactions, ATP is produced by chemiosmosis through an electron transport chain" is true.
During the light reactions of photosynthesis, light energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP through a process called chemiosmosis. In this process, an electron transport chain (ETC) is established across the thylakoid membrane of the chloroplast. As electrons pass through the ETC, protons are pumped from the stroma into the thylakoid space, creating a proton gradient.
This process is essential for the production of ATP, which is the energy currency of the cell, and is used in a variety of cellular processes, such as cell division, DNA replication, and protein synthesis. The light reactions of photosynthesis are a crucial step in the process of photosynthesis and provide the energy needed for the Calvin cycle, which converts CO2 into organic compounds.
Therefore, the given statement is true.

Air masses get from one place to another through evaporation
What locations do evaporation and transpiration occur in?
Water that evaporates into the atmosphere from the soil surface, the groundwater table's capillary edge, and land-based bodies of water is referred to as evapotranspiration. Transpiration, or the transfer of water via plants from the soil to the atmosphere, is also a component of evapotranspiration.
Water on the surface of the earth enters the soil through a process called infiltration. The rate at which soil can absorb rain or irrigation is known as infiltration rate in soil science. It is expressed in millimeters per hour or inches per hour. As the soil becomes saturated, the rate slows.

Suppose we have a disease phenotype that is determined by a single gene with two alleles. Further suppose it follows a autosomal recessive mode of inheritance with reduced penetrance. We have an individual who is unaffected (does not have the disease phenotype) and whose genotype is unknown. We cross this individual with a true-breeding affected individual. How many possible genotypes can this unaffected individual have at the disease locus
Answers
Answer:
three (3)
Explanation:
Penetrance can be defined as the proportion of individuals that have mutations associated with a genetic disorder and exhibit symptoms of having that genetic disorder. Moreover, reduced penetrance, also known as incomplete penetrance, indicates that an individual who carries mutations for a disorder but may never develop this disorder. Incomplete penetrance is frequent in some types of cancer, where individuals carry mutations (for example, mutations in the BRCA1 gene which is associated with an increased risk of ovarian cancer), but they may do not develop this condition during their lifetime. Incomplete penetrance may be a result of the interaction between genetic and environmental factors.

which of the following hypotheses emphasizes isolation and environmental factors as forces of natural evolution?
Answers
A form of hypothesis that emphasizes isolation and environmental variables as causes of natural evolution stresses stressful environmental circumstances.
According to the principle of natural selection, organisms breed more young than they can withstand in their surroundings. Those who are more physically capable of surviving, maturing, and reproducing. We refer to this as allopatric speciation. Allopatric, peripatric, parapatric, sympatric, and artificial speciation are the five different forms.
When a species divides into two distinct groups that are separated from one another, allopatric speciation takes place. The impact of isolation was proposed to be explained by the "social control theory." According to the social control hypothesis, internalized commitments to and overt influence from network members tend to deter unhealthy habits and promote healthy ones.

Does the pharynx of human respiratory system have cartilage and epithelium?
Answers
Answer:
There is no cartilage but there is epithelium
Explanation:
The pharynx of the human respiratory system does not contain cartilage.
The pharynx, part of the human respiratory system, is a muscular tube that connects the nasal cavity and mouth to the larynx and esophagus. It serves as a passage for air and food. The gorge is made up of several regions, each with its own distinctive features.
The nasopharynx, the top part of the throat, contains no cartilage. Instead, it is lined with pseudostratified ciliated epithelium.This special epithelium helps to trap and transport mucus along with any particles or pathogens in the digestive system for elimination.
These regions also lack cartilage but are lined with stratified squamous epithelium. This type of epithelium provides protection from mechanical stress and potential abrasion caused by the passage of food and other substances down the pharynx.
