Explanation:
Blood vessels are vessels that carry blood through organs and tissues. The five types of blood vessels are: arteries, veins, arterioles, capillaries, and venules. The main function of blood vessels is to carry blood throughout the body.
Answer:The blood vessels are the components of the circulatory system that transport blood throughout the human body.[1] These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. They also take waste and carbon dioxide away from the tissues. Blood vessels are needed to sustain life, because all of the body's tissues rely on their functionality.[2]
There are five types of blood vessels: the arteries, which carry the blood away from the heart; the arterioles; the capillaries, where the exchange of water and chemicals between the blood and the tissues occurs; the venules; and the veins, which carry blood from the capillaries back towards the heart.
The word vascular, meaning relating to the blood vessels, is derived from the Latin vas, meaning vessel. Some structures – such as cartilage, the epithelium, and the lens and cornea of the eye – do not contain blood vessels and are labeled avascular.

All of the following would be visible on a karyotype except
aneuploidy.
polysomy.
trisomy.
homologous chromosomes.
Answer: I think aneuploidy id wait for someone else to confirm this
Explanation:
All of the following would be visible on a karyotype except is aneuploidy
How to identify karyotype?The normal karyotype of the species is described as 46, may XX or XY, in which the first number of chromosomes is followed by a comma indicating the chromosomes. Thus, 46, XX corresponds to the karyotype of a woman; and 46, XY represents a male karyotype.
Aneuploidy is the presence of an abnormal number of chromosomes in a cell so this is the exception.

1. Hypothesize in what type of environments it would be advantageous for a protist to be autotrophic, heterotrophic, or mixotrophic.
Answer:
See below
Explanation:
Protists fall into the category of eukaryotes. They are diverse in nature and typically are found to be single celled organisms containing very organized structures.They are classified based on what is their source of nutrition.
Autotrophic - capable of photosynthesis to produce their own food, so an environment where sunlight, CO2 and water is available.
Heterotrophic - feed on other organisms , an environment where prey is plenty and very limited or no access to sunlight.
Mixotrophic - a combination of the above two, an environment with all of the aforementioned factors present.
describe the process involved when the human eye views an object
Answer:
How the eye view an object.
As the object appear before the eye,
Light enter the cornea, the domeshape that cover the front eye.
The light then enter the pupil through the cornea.
The light then hit the eye lens, a transparent structure that focuses the light through the virteous humour, a gel like substance that surrond the retina.
The retina then receive the light that was focused by the eyes lens and transform it to electrical impulses.
The electrical impulses is then transmitted to the person through the optic nerve,
The optic nerve then interpret it as the object view.
Explanation.
Eyes are organs of the visual system. They provide both humans and animals with the ability to receive and process visual information, thereby enabling different photo response functions that are independent of vision. Eyes detect light and convert it to electrical impulses in neurons. The optic nerve then send it to the brain which is then is interpreted as what is seen.

During osmosis Group of answer choices pure solvent and a solution both diffuse at the same time through a membrane.
During osmosis A) pure solvent diffuses through a membrane but solutes do not. B) pure solutes diffuse through a membrane but solvent does not. C) pure solvent and a solution both diffuse at the same time through a membrane. D) gases diffuse through a membrane into a solution and build up pressure.
Answer:
Explanation:A.
The net movements of solvent from the region of higher water potential (solvent) to a region of lower water potential(solute) through a semipermeable membrane is called osmosis. It is a peocess where the solute dissolved in the solvent and the resulting solution pass the selective permeable membrane,A selective permeable is the type which allows water,gases, and non polar molecules to pass through, but restrict polar and other large molecules through its walls.
Generally during osmosis,the water molecules and solute molecules interacts.These interaction ,due to dipole dipole effects of the water molecules, reduced the pressure of water on the solute in solution .Consequently, the water molecule of the pure water (the solvent )exerts more pressure on the weaker solution i,e higher water potential
Hence,this pressure forces water molecules across the semi permeable membrane,from higher water potential to lower water potential.It is the major biological process of plants and animals.
Somatic cells in elephants have 56 chromosomes. How many chromosomes would be carried by the gametes produced by elephants
Answer:
As somatic cells are diploid (2n) 2n=56
gametes receive only haploid set so, n=28
The number of chromosomes carried by the gametes produced by elephants would be : 28
Given that The elephants posses 56 chromosomes in its somatic cells and somatic cells are known as diploid cells ( i.e. 2n ) while the gametes will only carry a haploid set of chromosome ( i.e. n ).
Determining the number of chromosomes contained in the gametes
since ; 2n ( chromosomes of a somatic cell ) = 56
∴ n ( chromosomes contained in a gamete ) = 56 / 2 = 28
Hence we can conclude that The number of chromosomes carried by the gametes produced by elephants would be : 28.

How can protists exhibit both animal-like and plant-like characteristics?
A heterotrophic and chlorophyll protist
Food is ingested by protists in three forms. We produce, eat and digest their own organic molecules. Meat ingestion or english bacteria ingests protists. The cell wall and cell membrane are stretched to create an alimentary vacuolum around the foodstuff. Enzymes extract the food inside the food vacuole. At the other side, absorbent protists consume food molecules through their cell membrane by diffusion. In decomposition, absorbent protists play a crucial role. They are assumed to be essential decomponents. Light energy is used to make your own food by big farmers including photosynthetic protists.

Glycogen Synthase Kinase:_______.
A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.
B. Phosphorylates glycogen phosphorylase
C. Phosphorlyates Casein Kinase.
D. Is activated by the insulin signaling pathway.
Answer:
A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.
Explanation:
Glycogen synthase kinase (GSK) is a type of enzyme capable of phosphorylating serine and threonine residues on the glycogen synthase (GS). The insulin hormone activates the synthesis of glycogen by dephosphorylating GS, but it is a mechanism that depends on the previous phosphorylation of GS by Casein Kinase (CK). GSK is also known to phosphorylate the insulin receptor (IRS), and thus controlling glucose metabolism.

The genomic DNA of an organism has a base composition of 40% C-G base pairs and 60% A-T base pairs. Assuming a random sequence of bases, what is the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3'?
Answer:
The correct answer is (0.2)^4.
Explanation:
Based on the given information, the given genomic DNA is A-T rich, and the base pair composition is C-G = 40 % and A-T = 60%. Therefore, as per Chargaff's rule, Each C and G will possess 20%, and each A and T will possess 30%.
Therefore, the probability of each base will be,
C = 20/100 = 0.2
G = 20/100 = 0.2
A = 30/100 = 0.3
T = 30/100 = 0.3
Now the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3' will be 0.2 * 0.2 * 0.2 * 0.2 = (0.2)^4.
Which is the pair of the enzyme activities most significantly affected by glucagon- and insulin-dependent phosphorylation and dephosphorylation of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFKFB)?
a. hexokinas ::::: glucose-6-phosphatase
b. phosphofructokinase ::::: Fructose-1,6-bisphosphatase
c. pyruvate kinase :::::: pyruvate carboxylase
d. glycogen synthase ::::: glycogen phosphorylase
e. None of these
Answer:
b. Phosphofructokinase; Fructose-1,6-bisphosphatase
Explanation:
Glucagon is a hormone which functions to initiate gluconeogenesis whwreas insulin functions to initiate glycolysis.
Fructose-2,6-bisphosphate (F26BP) is an allosteric regulator of the glycolytic and gluconeogenic enzymes phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase (FBPase-1).
It stimulates glycolysis and inhibits gluconeogenesis by binding to its allosteric site on phosphofructokinase-1 reducing its affinity for the allosteric inhibitors ATP and citrate .
It is formed by phosphorylation of fructose-6-phosphate catalyzed by phosphofructokinase-2 and is broken down by fructose-2,6-bisphosphatase which are two separate enzymatic activities of a single, bifunctional protein (PFK-2/FBPase-2).
Phosphorylation of PFK-2/FBPase-2 due to glucagon release enhances its FBPase-2 activity thereby stimulating gluconeogenesis and inhibiting glycolysis.
Dephosphsorylation of PFK-2/FBPase-2 due to insulin release enhances its PFK-2 activity, thereby stimulating glycolysis and inhibiting gluconeogenesis.

One of the procedures for cloning foreign DNA segments takes advantage of restriction endonucleases such as HindIII that produce complementary single strand ends (sticky ends). These enzymes produce identical sticky ends on cleaved foreign DNA and on the vector DNA into which you insert your DNA. Assume you have inserted your favorite gene into the HindIII site of the Bluescript cloning vector with ligase, you amplified it in E.coli, and isolated a large quantity of the plasmid with the insert. How do you excise your favorite gene from the plasmid?
Answer:
Restriction endonucleases are utilized to cut the deoxyribonucleic acid at a specific Restriction site. HindIII is an example of Restriction endonuclease. The Restriction site of HindIII is as per the following:
5'A*AGCTT3'
3'TTCGA*A5' (* represents restriction site)
The Restriction endonuclease cuts the particular gene from the foreign DNA and produces numerous fragments with the sticky ends. The part of the outside DNA which contains the gene of intrigue or a particular gene is ligated with the plasmid.
On the off chance that foreign DNA and plasmid DNA are separated by the same Restriction endonuclease, they will create sticky ends integral to one another. In this way, the segment of foreign DNA can be ligated to the plasmid DNA by the assistance of DNA ligase at the integral sticky end to shape a recombinant DNA.
Additionally, by the assistance of the same Restriction endonuclease for example HindIII for this situation, the recombinant plasmid can be treated with a similar Restriction endonuclease to extract the ideal gene or gene of intrigue.
