Explanation:

The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

Answer: Depends on the balance between blood pressure and osmotic pressure.

Explanation:

The capillaries are part of the microcirculation that transports nutrients to the tissues and removes cell excreta. The walls of the capillaries are extremely thin, constructed of single - layer, highly permeable endothelial cells. Therefore, water, cell nutrients and cell excreta can all interchange quickly and easily between the tissues and the circulating blood.

The tissues of the body is made up of soo many capillaries which helps to deliver blood and it's contents to it. The hydrostatic pressure in the capillaries tends to force fluid and it's dissolved substances through the capillary pores into the interstitial spaces. Conversely, osmotic pressure caused by the plasma proteins( called COLLOID OSMOTIC PRESSURE) tends to cause fluid movement by osmosis from the interstitial spaces into the blood. This osmotic pressure excreted by the plasma proteins normally prevents significant loss of fluid volume from the blood into the interstitial spaces.

Therefore, a balance between hydrostatic pressure in the capillaries which is influenced by blood pressure and osmotic pressure in order for a net flow of fluid into or out of a capillary to occur.

Answer:

d Meth-Arg-Asn-Pro-Leu-stop

Explanation:

This question is describing the processes of transcription and translation of protein synthesis. Transcription is the synthesis of mRNA from DNA while translation is the synthesis of amino acid from mRNA. In this question, the following DNA sequence is given:

TAC/GCA/TTA/GGC/AAC/ACT

- Following the complementary base pairing rule i.e A-U, G-C, T-A etc, the following mRNA transcript will be produced after transcription:

AUG/CGU/AAU/CCG/UUG/UGA

- Using the genetic code, the following amino acid sequence will be produced from the above mRNA sequence after translation:

Methionine/Arginine/Asparagine/Proline/Leucine/STOP.

Answer:

Glucose present as monomers within the cell will exert more osmotic pressure than a single glycogen molecule, resulting in endosmosis and the lysing of cells.

Also, the presence of free glucose molecules will result in increase in weight of the liver due to lack of efficient packing as in glycogen as well as the association ofnthe glucose molecules with water molecules.

Explanation:

Glycogen is a polysaccharide composed of glucose monomer units linked to Each other by α-1,4-glycosidic binds. α-1,6-branches arises at about every 10th glucose residue in the straight chain. Thus animals more glucose molecules to be stored within a much smaller space, thereby incresing the bulkiness of glycogen. Glycogen molecules are insoluble in the aqueous medium of the cell because it doesn't have enough free polar groups to participate in hydrogen bonding with water and are stored as granules and therefore do not affect the water potential or osmotic balance of the cell.

On the other hand, glucose molecules are highly soluble in water because it has many free polar -OH grours that form hydrogen bonds with water. If the glucosyl residues in large numbers of glycogen molecules were replaced with an equivalent number of molecules of free glucose, the free glucose will exert a high osmotic pressure inside the cell, causing the entry of water in the cell by endosmosis resulting in swelling and lysis ofnthe cell. Also, the space occupied by these free glucose units within the cell will be much larger than that of glycogen whichmenables efficient packing ofthe glucose molecules.

Answer:

This question lacks options, the options are;

A. parietal layer.

B. serous membrane.

C. nuclear membrane.

D. mucous membrane.

The answer is B

Explanation:

The serous membrane is a covering membrane found in living systems. The serous membrane covers the surfaces of certain structures in the body such as heart, lungs etc. where they secrete lubricants that reduce friction during movement.

The structure of the serous membrane is composed of a sheet of simple squamous epithelial cells (secretes the lubricants) that folds onto itself to form a double layer. The layers are joined by a connective tissue.

Answer:

The factor that is improved by adding pocket gophers to an abandoned pasture is:

B. Colonization is limited by poor dispersing plant species.

Explanation:

In ecological management, colonization describes the action by a plant or animal to establish itself in an area.  When pocket gophers are added to an abandoned pasture, the area is repopulated by these rodents.  By their nature, pocket gophers move some quantity of soil annually, thereby aerating the soil.  Moreover, they build tunnels, which they later abandon for other species as natural habitat.  They also leave some waste products to fertilize the soil, making the ecosystem alive again.

Answer:

The Hawaiian honeycreeper bird population will decrease because they rely on the Hawaiian silversword plants for survival.

Explanation:

The destruction of Hawaiian silversword plants due to human development hurts the Hawaiian honeycreeper bird population as the bird exists in a mutual relationship with the plants.

Hawaiian honeycreeper bird has a mutual relationship with Hawaiian silversword plants, where the bird feeds on the plant's nectar and pollinates the flowers. If the plant population decreases, it will result in a reduced food supply for the bird which decreases their population size.

Loss of the silversword plants also destroys their habitat which can impact their population. Therefore, human development results in a decrease in the Hawaiian honeycreeper bird population.

However, the loss of the honeycreeper bird population also affects the ecosystem as they play a very important role in seed dispersal and plant reproduction which reduces plant diversity and also negatively impact other species that depend on the Hawaiian silversword plants for food.

Therefore, the destruction of Hawaiian silversword plants hurts the Hawaiian honeycreeper bird population as the bird exists in a mutual relationship with the plants.

Answer:

D. Both X and  Y chromosomes

Explanation:

Sex linked is a trait in which a gene is located on a sex chromosome. In humans, the term generally refers to traits that are influenced by genes on the X chromosome. This is because the X chromosome is large and contains many more genes than the smaller Y chromosome.

Answer:

yes

Explanation:yes

Complete question:

1) Inspired by Gregor Mendel, you visit a local greenhouse to see what a pea plant looks like in person. You spot a plant in the corner and immediately notice that it exhibits the purple trait of the flower color character. This character is controlled by one gene with two alleles, the dominant purple P allele, and the recessive white p allele. Identify what you know for certain based on your observation. Check all that apply.

2) In another corner of the greenhouse, you find another pea plant. This plant, however, exhibits the white trait of the flower color character. The greenhouse plant breeder approaches you and mentions that he plans to cross-fertilize the two plants that you have seen. He offers to let you know how the offspring turn out. Without realizing it, the breeder is actually conducting a

3) If you were able to examine hundreds of offspring from this cross, what ratio of purple flowers to white flowers would you observe:

4) In a few months, you receive a brief note from the breeder that he checked the four offspring and three have the purple trait and one has the white trait. Since only four offspring were produced, there are not necessarily enough offspring to observe the ratio you predicted. What is the probability of observing three purple and one white offspring:

Answer:

The funny thing is that the water that falls from the sky as rain today, might have fallen last week, last month, last year or thousands of years ago. It is the greatest recycler of all time! There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection.

Answer:

The correct answer is - B. Water can have a cold temperature.

Explanation:

Qualitative measurement is a type of measurement that is not based on numerical or numbers but is completely based on the quality of the particular thing. It can be distinguished on basis of the term quality which is based on the character of the substance or condition whereas quantitive is which is based on numerics or numbers.

Among these, all the three choices have numerical measurement but the choice in which it is expressed that water can have cold temperature is qualitative measurement as cold is the quality of the water here.
