The largest endocrine gland (s) that makes 3 hormones that affect the metabolism is the: *
A. pituitary gland
B. thyroid gland
C. pancreas
D. adrenal gland
Answer:
The largest endocrine gland (s) that makes 3 hormones that affect the metabolism is the: thyroid gland.
The largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.
What do you mean by Endocrine Gland?An endocrine gland may be defined as a type of gland which consists of several organs that make hormones and release them directly into the blood so they can travel to tissues and organs all over the body. These hormones control many important functions in the body, including growth and development, metabolism, and reproduction.
The pancreas is the largest endocrine gland that significantly makes three hormones namely, Insulin, Glucagon, and Somatostatin. These hormones are actively involved in the regulation of metabolism by numerous mechanisms.
For example, insulin lowers the level of sugar in the blood, while glucagon increases the level of sugar by transforming its storage form.
Therefore, the largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.

Match the body cavity type to its proper description. - Coelomate - Pseudocoelomate - Acoelomate - Coelom A. A fluid or air-filled space between the digestive tract and the outer body wall. B. Completely lacks a body cavity between the digestive cavity and outer body wall. C. Has a body cavity lined by tissue derived from the mesoderm and by tissue derived from the endoderm. D. Has a body cavity completely lined by tissue from the mesoderm. E. Germ Layer
Answer: A. A fluid or air-filled space between the digestive tract and the outer body wall. - Coelom
B. Completely lacks a body cavity between the digestive cavity and outer body wall. - Acoelomate
C. Has a body cavity lined by tissue derived from the mesoderm and by tissue derived from the endoderm. - Coelomate
D. Has a body cavity completely lined by tissue from the mesoderm. - Pseudocoelomate
E. Germ Layer- Coelomate
Explanation:
Coelom is a fluid filled body cavity which stores food, blood like fluid in it in some animals.
Those organisms which do not possess the body cavity or coelom they are called as acoelomate. Example, Platyhelminths
Those animals which have a body cavity derive from the germinal layers ectoderm, endoderm, and mesoderm are coelomate. Example, Annelids
Those animals which have scattered pouches which are not lined by all germinal layers instead one mesoderm will not be able to form coelom. These are called as pseudocoelomate. For example, Nematodes.

For the voltage-gated sodium channel to allow sodium into the cell:_______.
a. the activation and inactivation gates must both be open
b. only the activation gate must be open
c. only the inactivation gate must be open
d. the inactivation gate must be closed shortly before the activation gate opens
e. the activation and inactivation gates must both be closed
Answer:
The correct option is - (a) the activation and inactivation gates must both be open.
Explanation:
Option (a) is correct because of the following reason -
The axonal membrane is at its natural resting potential until an action potential occurs, and [tex]Na^+[/tex] channels are deactivated and blocked on the extracellular side by their activation gates. The activation gates open in response to an electric current, allowing positively charged [tex]Na^+[/tex] ions to flow into the neuron through the channels. When enough [tex]Na^+[/tex] has penetrated the neuron and the membrane potential has reached a certain level, the [tex]Na^+[/tex] channels inactivate themselves by closing their inactivation gates at the height of the action potential. The inactivation gate can be thought of as a "plug" tethered to the intracellular alpha subunit's domains III and IV. When the inactivation gate is closed, the flow of [tex]Na^+[/tex] through the channel is stopped. As a result, both the activation and inactivation gates must be open to enable sodium ions to enter the cell.
Hence , the correct option is (a).
What features of eukaryotes provide additional opportunities for the regulation of gene expression compared to bacteria? Select all that apply. Select all that apply. interaction with external environment transcription and translation are coupled processes separated processes of transcription and translation presence of chromatin opportunity for posttranscriptional and pre-translational regulation activation of all genes in genome
Answer:
separated processes of transcription and translation presence of chromatin opportunity for posttranscriptional and pre-translational regulationExplanation:
Since there is no nucleus surrounding the genetic material in prokaryote cells, the transcription and translation processes occur simultaneously. Transcription stops when a protein is not necessary. So the control of protein synthesis is regulated by transcription and not translation. Once the transcription is on, all the following steps must follow it.
Transcription is the process that controls the genic expression in bacteria.
Eukaryotes do possess a nuclear membrane that separates the genetic material from the rest of the cell. The transcription process occurs inside the nucleus membrane, while the translation process occurs outside. In the cytoplasm occur the translation process and protein synthesis. Genic regulation can happen in any of these processes in different regions of the cells.
In eukaryotes, the regulation of the genic expression control might happen at different levels:
Epigenetic level: When DNA molecules open and nucleosomes separate to join the transcriptional factorsTranscription level: When the messenger RNA is being transcriptedPost-transcription level: When mRNA goes to the cytoplasm Translation level: During the protein elongationPost-translation level: Once the protein synthesis is over.A population of raccoons is thought to be in Hardy-Weinberg equilibrium for a tail-length gene. The frequency of the dominant allele (long tails) is 0.8. When a certain forest was surveyed, the scientist was able to tag 25 animals, which were all long-tailed. Does the lack of short-tailed animals suggest that the population is out of Hardy-Weinberg equilibrium in this forest?
A. Yes, because the survey shows 100% AA individuals, so the short tils must have been selected against.
B. No, because you would only expect 4 of the surveyed racoons to be short-tailed, so they may have been missed by chance.
C. Yes, because 20% of the surveyed raccoons should have been short-tailed.
D. No, because you would only expect 4% of the raccoons to be short-tailed, so they may have been missed by chance.

The purpose of mitosis is to ___, while the purpose of meiosis is to ____.
a) make new cells, and only germ-line cells do it;
b) make eggs or sperm, and all the body cells do it make eggs or sperm, and only germ-line cells do it;
c) make new cells, and all body cells do it make eggs or sperm, and only somatic cells do it;
d) make new cells, and all body cells do it make new cells, and all body cells do it;
e) make eggs or sperm, and only germ-line cells do it
Answer:
A) make new cells(somatic cells)and only germ-line cells do it(meiosis)
Explanation:
Meiosis is the process through which germ cells that produce gametes such as sperm and eggs are formed. It is an equatorial division that involves the parental cell dividing into daughter cells each containing similar genetic material as the parents cell and this can be passed on to successive generation.
While Somatic cells are cells that form the building blocks of the body, they are the actively divided body part and only divide by mitosis.
Meiosis produces germ cells while mitosis produces somatic cells.
Human caused reductions of biodiversity, include pollution, invasive species, and overexploitation.
O True
O False
Answer:
True
Explanation:
Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.
Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.
Some of the principal human activities responsible for biodiversity loss are
the uncontrolled use of unrenewable resources, overexploitation of renewable resources; land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures; the unplanned advance of cities, and opening of new roads to connect those cities.All of them involving
deforestation and fragmentation of natural landscapes; water, air, and soil pollution, species loss, and reduction of biodiversity.With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.
Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.
But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking
The respect for nature, People´s education at different levels to care and protect wildlife, Interest in keeping ancestral knowledge, Planning and previous environmental impact studies, Policies to control human activities, Caring involved government.If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.

C hope this help
Explanation:
Many scientists say that there is a good reason for gaps in the fossil record. Can you explain why some extinct animals and plants were never fossilized?
Answer:
For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.

Biology 1 Post Lab Questions: 1. Which method appear · which method appeared to have the most dramatic denaturing effect on egg albumin? Why do you think this method had a greater effect?
Hello. You have not introduced the methods used to denature the egg albumin. However, the most efficient protein denaturation method is the heating method.
The denaturation of a protein, such as albumin, occurs when an element causes the complete destruction of the protein's three-dimensional structure, in a completely irreversible way. The best way to do this is through heat. In this way, through a heating method, the heat breaks the hydrogen bonds that promote the structure of the protein, leaving it completely denatured.
