Answer:
Clomid tricks the body because it tells the brain that estrogen levels are low, thereby leading to higher production of this hormone
Explanation:
There are many types of hormones that are regulated by the negative feedback mechanism (where hormone feeds back to decrease its production). Clomid is a drug used to treat female infertility by making the body think that the concentration of estrogen is low, which induces the secretion of Follicle-stimulating (FSH) and luteinizing (LH) hormones by the pituitary gland. The estrogen hormone exerts negative feedback on the Gonadotropin-releasing (GnRH) hormone, which is responsible for the release of FSH and LH. High FSH levels stimulate the growth of follicles in the ovaries, which will be released during ovulation.

How does the injection of insulin affect the signal transduction pathway of type 1 diabetics?
a. Injected insulin prevents the glucose from binding to cellular protein receptor.
b. Insulin acts as a secondary messenger that cascades the message to allow glucose into the cell.
c. Insulin is absorbed into the cytoplasm and binds with the transcription factor to make it active.
d. Protein receptors on the cell bond to the insulin, which allows glucose to enter the cell.
Answer:
The correct answer is D.
Explanation:
To act on target cells, insulin binds to a specialized protein that is located on the membrane of your target cells: the insulin receptor. When insulin binds to the receptor, it activates a cascade of signals within the cell (a process called signal transduction), which is essential for insulin to have an effect on its target tissues. Insulin increases the entry of glucose into cells and causes the number of certain proteins specialized in glucose transport to increase in the membrane of their target cells, such as adipocytes (adipose tissue cells) and skeletal muscle cells.
Answer:
The correct answer is B, b. Insulin acts as a secondary messenger that cascades the message to allow glucose into the cell.

Meter is called a standard unit.Give reason.
Answer:
The meter is not called a fundamental unit, except informally by some people. In the International System of units (SI), the meter is one of seven base units. Base units can be defined in terms that do not depend on no units beyond other base units or natural constants (e.g., the speed of light). Using no more than those seven base units, other units can be defined and those are called derived units. No factors or coefficients other than one are used to show how they relate to each other

How might factors like hormones, chemicals, and the weather influence criminal behavior?
Answer:
These substances alter signaling pathways associated with cognitive functions
Explanation:
It is well known that cortisol hormone is secreted by the adrenal glands in stressful situations. In criminals and convicts, constant and high levels of cortisol have been observed, thereby it is believed that this hormone is associated with criminal behaviors through a 'constant stress-stimulation state'. Moreover, addictive drugs are known to literally destroy the brain. These drugs bind to hormone-like receptors involved in feedback responses. In consequence, after drug consumption, neural pathways will be altered and cognitive functions will be harmed. Finally, evidence linking wheater with criminal behavior is not conclusive.

As the adrenal gland releases glucocorticoids, which of the following effects may be observed? a) Increased blood levels of amino acids
b) Decreased blood pressure and volume
c) Decrease in immune system function
d) Lipid breakdown in the liver will increase
e) Increased water absorption in the kidney
f) Increased blood glucose levels
Answer:
The correct option is F) Increased blood glucose levels
Explanation:
The release of glucocorticoids into the body is part of the body's chemical process for managing stress and ultimately prepares the body for fight or flight.
The body anticipates that it may consume additional fuel/energy during elevated stress levels, it therefore through the adrenal cortex which is situated above the kidneys, sends glucocorticoids into the body.
The glucocorticoids trigger the body's metabolism with regard to breaking down stored fuel in order to produce the required energy that it needs.

g What are the three basic assumptions of Darwinian evolution? Group of answer choices Presence of phenotypic variation, some phenotypic variation due to genetic variation, the given trait has an impact on fitness Presence of phenotypic variation, environmental variation, the given trait has no impact on fitness Presence of phenotypic variation, environmental heritability, the given trait has an impact on fitness Presence of phenotypic variation, trait present in only the mitochondrial DNA, the given trait has an impact on fitness
Answer:
1- Presence of phenotypic variation
2- some phenotypic variation due to genetic variation
3- the given trait has an impact on fitness
Explanation:
The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.

Which event might occur if the populations of producers in an ecosystem became unstable? A) The direction of energy in the food web would change directions and flow toward the producers. B) Decomposers would become the primary energy source. C) The number of primary consumers would decrease dramatically. D) The energy flow into the food web would decrease or increase along with changing populations of producers. THANK YOU !!! :-)
Answer:
If the populationsl of producers in an ecosystem became unstable the energy flow into the food web would decrease or increase along with changing populations of producers.
Answer:
Answer: option D.
Explanation:
Hey, there!
Reason: The reason is, when the number of producers are unstable, the flow to enegry from abiotic components to biotic components will be destructed. There will not be proper flow of enegry in whole ecosystem, which usally changes the flow of enegry as per the number of producers.

A mutation occurs, and cytosine is replaced with adenine. What impact do you think this will have on the DNA structure?
Adenine is larger than Cytosine base pair which make it unable to base pair properly with the guanine on the opposing strand. This will cause the DNA to bulge.
What is Mutation?Mutation refers to a sudden change. It is a change in the nucleic acid sequence of an organism's genome. This results in changes to the cell's DNA sequence that can be caused by mistakes during cell division, or by exposure to DNA-damaging agents in the environment.
There are two major types of mutations which are:-
1. Germline mutations
This type of mutation occur in gametes
2. Somatic mutations
This type of mutation occur in other cells of the body.
There are also some types of mutations that are found. They are
1. Base substitutions
2. Deletions
3. Insertions.
Thus, Adenine is larger than Cytosine base pair which make it unable to base pair properly with the guanine on the opposing strand. This will cause the DNA to bulge.

The relative concentration of each in the plasma membrane is partly regulated by the:_______
Answer:
ion channels
Explanation:
The plasma membrane plays a critical role in regulating and maintaining ionic potential inside the cell, relative to ionic concentration present outside the cell. The ion channels are specific, in that they only recognize and allow particular ions to pass through and block the rest. Their opening and closing depends on the ionic potential during that time period.
