Explanation:

Learned it in science class lol.

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:

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.

Explanation:

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:

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.

Answer:

Capillary exchange is the exchange of fluid from the capillaries into the interstitial fluid and vice versa. Diffusion, transcytosis, and bulk flow are three mechanisms that facilitate capillary exchange.

The blood plasma or interstitial fluid exerts a pressure of the fluid on the capillary walls known as Hydrostatic pressure. Osmotic pressure is a pressure exerted by proteins either in the blood plasma or interstitial fluid called oncotic pressure.

Lymphatic capillaries gather lymphatic fluid and regulate the pressure of interstitial fluid due to the forces of hydrostatic or oncotic pressure. An essential role of the lymphatic system is to return the fluid to the blood.

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.

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:

Explanation:

Allosteric regulation is a common mechanism of regulation of enzyme activity, which generally involves key enzymes in metabolic pathways. Allosteric modulation occurs when a substance/molecule called 'allosteric regulator' binds to an enzyme at a site other than the enzyme's active site, thereby triggering a conformational change in the enzyme and thus affecting its activity. Moreover, covalent modifications such as phosphorylation, acetylation, methylation, etc, are also involved in the regulation of enzymatic activity in metabolic pathways. For example, phosphorylation is a type of reversible covalent modification of proteins consisting of the addition of phosphate groups at specific amino acid residues (i.e., serine, threonine, and tyrosine) by specific enzymes known as protein kinases. Phosphorylation alters the three-dimensional (3D) structure of proteins, thereby turning the substrate or cellular pathway to active and/or inactive. Finally, both transcriptional and post-transcriptional mechanisms are also able to control the expression of enzymes involved in signaling pathways. Transcriptional mechanisms are capable of limiting the amount of mRNA that is produced from a given gene (in this case, an enzyme encoding gene), whereas post-transcriptional mechanisms such as, for example, RNA interference pathways, control the translation of messenger RNA (mRNA) molecules into proteins.

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.

Answer:

the total number of being shared is six

Answer:

C.

Explanation:

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).
