Answer:
The protein is a symport protein.
Explanation:
Transport proteins are proteins which are involved in the transport of solutes across the cell membrane. The binding of the solute to be transported across the membrane causes a conformational change in the shape of the protein, thereby moving the molecule to the side of nthe membrane it is to be transported. The difference in the concentration of the solute across the membrane known as concentration gradient is mainly responsible for the transport of molecules by the transport proteins.
There are three types of transport proteins: uniport, symport and antiport transport proteins.
Uniporters are involved in moving only one molecule across a membrane
Symporters are involved in moving two or more molecule across a membrane in the same direction.
Antiporters are involved in moving two or more molecule across a membrane in opposite directions.
From the description of the transport protein in the question, both solutes A and B are moved across the membrane simultaneously in the same direction. Therefore, the protein is a symport protein.
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

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.

What is the rapid change in a membrane's potential caused by the depolarization of a neuron?
Answer:
During depolarization, the membrane potential rapidly shifts from negative to positive. As the sodium ions rush back into the cell, they add positive charge to the cell interior, and change the membrane potential from negative to positive.
Explanation:
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.

Predict a change in the Earth's surface or effect observed at each of the following for
1 point each:
- TRANSFORM BOUNDARY
- DIVERGENT BOUNDARY
- CONVERGENT BOUNDARY
Answer:
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth. The rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year (cm/yr), or 25 km in a million years. This rate may seem slow by human standards, but because this process has been going on for millions of years, it has resulted in plate movement of thousands of kilometers. Seafloor spreading over the past 100 to 200 million years has caused the Atlantic Ocean to grow from a tiny inlet of water between the continents of Europe, Africa, and the Americas into the vast ocean that exists today.

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.

Question 1: Biodiversity and Ecosystem Health (20 points) a) Describe two ways of measuring biodiversity. Explain the relationship between biodiversity and ecosystem stability. As part of your explanation, discuss how susceptibility to disease in agricultural crops and in isolated tribal human populations provides evidence that supports this idea. (5 points)
Answer:
explanation below
Explanation:
A) Biodiversity is simply known as the number and variety of organisms found in a definite environment or region. Scientists have devised several ways of measuring biodiversity and the methods to be used depend on the type of organisms they are to count.
Canopy fogging – one of the ways of measuring biodiversity, has remained an effective way of obtaining details about the biodiversity of insects. It involves the act of spraying low dose of insecticides on a tree top, and when the insects fall from the trees, they are being collected on a large screen, that looks like a funnel.
Transact sampling is another way of measuring biodiversity and this time, with a transact line. The transact line is usually a measuring tape or rope that has been marked at set intervals.
b) Ecosystem stability is the ability of the ecosystem to maintain its steady state, even after it has experienced stress or disturbances. The biodiversity of an environment makes huge impact on the ecosystem stability in that particular area. It has been known that certain areas that have high levels of species and genetic diversity, are more likely going to an ecosystem that is complex, with varying food webs and biotic interactions. The increase in this complexity makes it more likely that the ecosystem of that area will rightly move back to a stable state whenever disturbances are experienced.
There are evaluated scientific evidence that shows that reduced biodiversity affects the transmission of communicable disease in agricultural crops, animals and humans. Loss of biodiversity usually increases susceptibility to diseases in plants and humans.

Two polypeptides, X and Y, have similar tertiary structures. X normally exists as a monomer while Y exists as a tetramer, Y4. What differences might be expected in the amino acid composition of X versus Y
Answer:
Due to number of amino acids.
Explanation:
The main differences might be expected in the amino acid composition of X versus Y because the X polypeptide is made up of one smaller unit of amino acid while on the other hand, Y polypeptide is made up of four smaller units of amino acids. The name of X is monomer which means composed of one amino acids while Y exists as a tetramer which means it has four amino acids. So we can conclude that the main difference between X and Y is the presence of number of amino acids.
Amino acids are organic compounds that are formed of amino, carboxylic and a side group. They bond to form protein structures.
The amino acids fold in various structures like primary, secondary, tertiary etc. The basic contrast in an amino acid arrangement of polypeptide X and Y is that the X is made of small units while Y is made of larger units.
X polypeptide is a monomer that is it only has one unit of amino acid while Y is a tetramer that is it has four-unit of amino acids.
Therefore, the number of amino acids is the main distinction between X and Y tertiary structures.

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).
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.
