Answer:
A group of plant hormones, which are accountable for growth and development is gibberellins. These hormones play an essential part in the initiation of seed germination. A lesser quantity, these hormones can play an essential function in elevating the speed of germination, and they instigate cell elongation so that the plants grow taller. The following are the essential uses of gibberellins:
1. Promote flowering
2. End seed dormancy
3. Increase the size of the fruit.
For the seeds to germinate, there is a need for seed dormancy to end, and this can be done with the use of gibberellins. The hormone also promotes the process of flowering, which helps in the production of more fascinating and larger specimens of flowers.
The flowering process also influences the rate of the growth of fruits. Gibberellins are also used in the generation of seedless fruits. The spraying of the hormone helps to enhance the size of the fruit.
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.

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.

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.

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.

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.
What makes ribosomal RNA useful as a molecular clock? (2 points) A large portion of the DNA ring is not vital to structure or function, allowing it to accumulate neutral mutations. Its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. A slow mutation rate makes it useful for determining evolutionary relationships between ancient species. It is only found in select organisms, making it easier to compare relationships between species that have it.
Answer:
The correct statement is that a slow mutation rate makes it useful for determining evolutionary relationships between ancient species.
Explanation:
The rRNA or ribosomal RNA has an application as a molecular clock because of many factors. It exhibits a very slow mutation rate, that is, around one million years because of which it stays highly conserved in all the organisms.

Michael, a new lab analyst, receives an email notifying him that his expected samples from a recent outbreak should be arriving soon. To prepare for his analysis, he decides to look into what type of diseases could be spread between animals and humans, as this is a new field for him. Michael has received limited information about the details of the outbreak from the epidemiologists that traveled to the site, but he does know that both animals and humans were infected by some type of virus. Michael looks through some of the lab manuals on how the samples will be handled once in the lab. While reading through these guidelines, he realizes that there are some terms he is not quite sure of.
Below are sentences that reflect the terms that Michael had to acquaint himself with while reading through the published guidelines from his laboratory. Please review the sentences below and fill in the blanks with the correct word(s).
a. arthropods
b. togaviruses
c. encephalitis
d. arbovirus

A virus that is able to be transmitted via _________like ticks, flies, and mosquitoes is considered __________.
2. Some arboviruses are able to move through the bloodstream and infect the brains of humans and arbovirus animals. This disease manifestation is called __________.
3. A_______ is a disease that can be transmitted from animals to humans.
4 Several encephalopathies, such as Eastern equine encephalitis and West Nile virus encephalitis, are caused by the____________ These viruses can infect humans and and animals such as horses and birds.
Answer:
the correct option is:
A virus that can be transmitted through arthropods such as ticks, flies, and mosquitoes is considered an arbovirus.
2. Some arboviruses can move through the bloodstream and infect the brains of human and animal arboviruses. This manifestation of the disease is called encephalitis.
Explanation:
Arboviruses are very dangerous for humans, some do not generate painful bites, others are hematofogous (they feed on human blood) and others are nocturnal, which bite humans at night without their perceiving it.
Diseases of these viruses that are transmitted by vectors such as arthropods cause encephalitis, cardiac, pulmonary disorders, etc.
An example of this is the Chagas disease that is generated by the transmission of the Vinchuca arthropod.
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.

narrowing of the coronary arteries due to buildup of debris along the artery
Answer:
The correct answer is coronary artery disease.
Explanation:
The narrowing of blockage of the coronary arteries, generally resulting due to atherosclerosis is known as coronary artery disease. Atherosclerosis also is known as the clogging or hardening of the arteries and is the accumulation of fatty deposits and cholesterol on the artery's inner walls.
These fatty deposits of plaques can prevent the flow of the blood to the muscles of the heart by physically choking the artery or by resulting in unusual artery function and tone. In the absence of a sufficient supply of blood, the heart becomes deficient of the essential nutrients and oxygen it requires to function appropriately. This can further result in angina or chest pain.
