Answer:

Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

Answer:

c. T state is low affinity and R state is high affinity.

Explanation:

Hemoglobin (Hb) is a multimeric protein molecule that transports oxygen from the lungs to the body's tissues in red blood cells. Hb exists in two quaternary states: 1- a T-state or deoxygenated conformation, which is referred to as 'deoxyhemoglobin'; and 2-a R state or fully oxygenated conformation, which is referred to as 'oxyhemoglobin'. The sequential model of cooperativity states that the conformation of a multimeric protein changes with each binding of a ligand, thereby sequentially changing its affinity for the ligand (i.e., cooperativity is dependent on ligand-induced). In consequence, this model states that the conformational state and affinity of Hb monomers change as they bind to oxygen.

Answer:

Answer:

1. False

2. False

3. True

Explanation:

1. Compliance is the capacity of a container to increase in size to allow it hold more content. Blood vessel, arteries and veins expand (increase in volume) to be able to accommodate a surge in blood flow, which is as a result of an increase in pressure of the blood from the heart pumping of the blood

Therefore, compliance in the tendency for blood vessel volume to increase as the blood pressure increases not decrease

The statement is false

2. A large compliance is indicative of being highly sensitive to changes in pressure

Compliance, C = ΔV/ΔP

From the above equation, a blood vessel with a large compliance, exhibit a large increase in volume when the increase in pressure is small

Therefore, the statement 'Blood vessels with a large compliance exhibit a small increase in volume when pressure increases a small amount; is false

3. The compliance of the vein ranges from 10 to 20 times (30 times in some literature) greater than arteries. A factor which can be affected by the vascular smooth muscle contraction or relaxation

Therefore, the statement, 'venous compliance is approximately 24 times larger than arterial compliance, so as venous pressure increases the volume of veins greatly increases' is true

Answer:

Places and location.

Explanation:

In gymnosperms, the pollen and the megaspores are produced in separate places. Megaspores made in cones that develop into the female gametophytes that is present inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores. while on the other hand, In angiosperms, the pollen and the megaspores are produced in separate structures, but within the same place i.e. flower which has both male and female reproductive organs.

The words that should be filled in the blanks are places and location respectively.

Megaspores may be defined as a spore in heterosporous plants giving rise to female gametophytes and usually larger than a microspore.

Gymnosperm produces both male and female cones. Both make the gametes needed for fertilization, which makes gymnosperm heterosporous.  In angiosperms, cones are not found, pollen is produced by the anthers of the stamens in flowers.

Therefore, the words that should be filled in the blanks are places and location respectively.

Answer:

cells will have glycogen molecules with branches of a single glucose residue

Explanation:

Glycogen debranching enzymes are proteins that catalyze the removal of branching from glycogen, which is a multibranched polysaccharide composed of glucose units and serves as a form of energy storage. These enzymes have two catalytic activities on a single polypeptide chain: glucosyltransferase and glucosidase activities, which are both required for glycogen breakdown. Glycogen degradation requires both glycogen phosphorylase and glycogen debranching enzymes. First, a glycogen phosphorylase acts to digest a glycogen branch down to four glucose residues. Subsequently, the debranching enzyme through its glucosyltransferase activity acts to transfer three glucose residues to a nearby branch of the glycogen chain. Finally, through its glucosidase activity, the debranching enzyme cleaves the remaining α-1,6 linkage in order to release free glucose.

Answer:

The correct answer is a. True

Explanation:

The information to produce a protein is coded in the cells in deoxyribonucleic acid (DNA). Transcription is the process in which a DNA sequence is copied into a ribonucleic acid (RNA) sequence. This RNA sequence is a messenger RNA (mRNA) because it will be then translated into a functional protein. For this, the DNA sequence is read and an RNA strand is synthesized by an RNA polymerase (an enzyme that synthesizes RNA molecules from a DNA template). During the process participate other proteins, such as DNA binding proteins, activators, coactivators, etc. (accessory proteins).

Answer:

Yes.

Explanation:

Yes, deposition can be possible for clay (0.001 mm) and silt (0.01mm) particles when the agent that carry its load is absent in that region such as wind. Wind is the agent that moves clay and silt particles with it so if there is high wind in a specific region, no deposition will occur while on the other hand, those areas where wind is not present, deposition will definitely occurs so we can say that deposition depends on the presence and absence of wind.

The genetic information is the encoded proteins passed through hereditary. The genetic information is stored in the chromosomes of the cel. Thus, option C is correct.

Chromosomes are the hereditary unit of an organism that passes from the parent cell through cell division and reproduction to the daughter cells.

The chromosomes comprise chromatin that is made of the proteins and DNA molecules wrapped around the histones to form a dense and compact structure.

They look like long threads that are present inside the cell's nucleus and code for specific information that gives the genotype and phenotype of an organism. It gets copied during the cell cycle.

Therefore, option C. chromosomes store the genetic information.

Population growth slow as size increases in the logistic model A : due to density-dependent factors is correct option.

In the logistic model of population growth, the slowdown in population growth as the population size increases is primarily attributed to density-dependent factors. Density-dependent factors are those that have a stronger impact on a population when its density (number of individuals per unit area) is higher. As a population grows and becomes more dense, competition for resources (such as food, space, and mates) intensifies, and factors like disease transmission and predation become more significant.

These density-dependent factors can lead to a decrease in birth rates, an increase in death rates, or both, which ultimately results in the population growth rate slowing down and eventually stabilizing at its carrying capacity (the maximum sustainable population size for a given environment). This pattern is characteristic of the logistic growth model, which describes a more realistic and sustainable form of population growth compared to the exponential growth model.

Answer:

b. diffusion.

Explanation:

Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.

This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.

During diffusion, molecules move from areas of high concentration to areas of low concentration.

In this context, the process by which dissolved gases are exchanged between the blood and interstitial fluids is referred to as diffusion.

On a related note, this process is also referred to as internal respiration because it involves the exchange of oxygen gas and carbon (II) oxide gas between tissue cell and capillaries.

Answer:

Breathing, the action of moving air or water across the surface of a respiratory structure, such as a gill or lung, to facilitate respiration (the exchange of oxygen and carbon dioxide with the environment).
