If blood flow through the afferent arterioles increases:
a. the smooth muscle in the vessel walls stretches to accommodate.
b. the increased flow and the stretch stimulates further relaxation of the arteriolar wall, lessening blood pressure.
c. the stretch stimulates further relaxation of the arteriolar wall, lessening blood pressure.
d. stretch stimulates vasoconstriction to reduce the flow.
e. the smooth muscle in the vessel walls stretches to accommodate the increased flow.
Answer:
d. stretch stimulates vasoconstriction to reduce the flow.
Explanation:
Afferent arterioles are a network of blood vessels that supplies the kidneys with blood. They branch from the renal artery and are important in blood regulation.
Myogenic mechanism is used to regulate blood flow to the kidney.
When blood flow increases to the afferent aterioles the smooth muscles its wall stretches and contracts to resist the pressure. This reduces blood pressure.
When the pressure reduces the smooth muscles relax to allow more flow of blood.
In a murder trial, which person testifying to the jury is classified as an eyewitness?
The medical examiner who found poison in the victim's stomach
An expert discussing evidence collected during an investigation
A defendant's best friend, who was out of town when the crime was committed
A person who claimed to see a car of a certain make/model leaving the scene of a crime
Answer:
A person who claimed to see a car of a certain make/model leaving the scene of a crime.
Explanation:
Key words to the answer:
"See"
"leaving the scene of a crime."
Eyewitnesses have a firsthand glimpse of events that occurred and they usually have to have seen something that has occurred to be considered a eyewitness, in this case the person who saw the Make/Model of the car that left the crime scene has some claims that can be used to find the criminal and also when the eye witness sees the car they can tell which direction it went in to give a bit of a clue(although this depends in certain situations). The eye witness can also be anyone who was anywhere near the crime scene when it happened or even a little bit after it happened.
Answer:
D. A person who claimed to see a car of a certain make/model leaving the scene of a crime
Explanation:
It is D because it would be the closest possible lead for finding who did the crime. Anyone around the time of the murder and anyone going in and out at the time is a suspect, even the eyewitness. If the eyewitness saw someone leaving the location moments before it was reported, that would be suspicious.
(lol among us vibes. it hyped me up for this moment.)
The medical examiner who found poison in the victim's stomach
It would not be this one because they were called after the crime took place, the medical examiner only saw the aftermath of said way to k!ll the person.
An expert discussing evidence collected during an investigation
The expert collected data of the crime scene after it had happened. Otherwise, this would not have been possible. So, they were not an eyewitness since they were not present at the time.
A defendant's best friend, who was out of town when the crime was committed
How would the addressed person out of town see the crime scene? Maybe they were threatened to leave the city? Anyway, it just would not make since for the best friend to be an eyewitness at the time of the crime if they were miles away.

Which feature of model 1 best illustrates how biological information is coded in a DNA molecule?
Using established recombinant DNA technology, you insert a gene from a human liver cell into a bacterium. The bacterium then expresses a protein corresponding to the inserted DNA. To your dismay, you discover that the protein produced is useless and is found to contain many more amino acids than does the protein made by the eukaryotic cell.
Assuming there is no mutation in the human gene, explain why this happened.
a. bacteria do not use splicing to edit RNA after its transcription.
b. rRNAs in bacterial cells contain more nucleotides than in eukaryotic cells.
c. bacterial RNA contains less stop codons.
d. amino acids in bacterial cells are specified by double codes.
Answer:
The fact that the amino acid chain is consistently having more amino acids than what is actually present can be attested to the fact of how gene expressions can be observed in the prokaryotic cell compared to the eukaryotic one.

Under normal conditions, gases diffuse through small holes in the leaves of a plant. When the weather is very hot and dry, plants may close these openings to conserve water. How are the closures most likely to affect photosynthesis? O They increase the rate of photosynthesis by increasing the amount of water in the leaf They decrease the rate of photosynthesis by preventing carbon dioxide from entering the leaf They increase the rate of photosynthesis by increasing the amount of oxygen in the leaf They have little or no effect on photosynthesis because gases do not take part in the process
Answer:
They increase the rate of photosynthesis by increasing the amount of water in the plant.
Explanation:
It is hot and dry when these openings close, so the Sun has to be out. Photosythesis is caused when the Sun and water are used by a plant to make food.
The answer to the question should be they increase the rate of photosynthesis by increasing the amount of water in the plant.
A diagram of photosynthesis is below.
The closures that are most likely to affect photosynthesis are they increasing the rate of photosynthesis by increasing the amount of water in the plant. The correct option is A.
What is photosynthesis?Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.
Photosynthesis depends on some factors. These factors are water, sunlight, and carbon dioxide. If there is a scarcity of any factors, it impacts the process of photosynthesis. If the water does not get enough water, it will dry and there is less chlorophyll for the plant to carry out photosynthesis.
Therefore, the correct option is A. They increase the rate of photosynthesis by increasing the amount of water in the leaf.

Activity A (continued from previous page) 4. Observe: Wait until the numbers are not changing very much. What do you notice about the solute concentrations inside and outside of the cell? This situation is called dynamic equilibrium
Answer:
Yes, dynamic equilibrium is present in the cell.
Explanation:
In dynamic equilibrium, the concentration of solute remain the same due to equal flowing of solutes inside and outside the cell so there is no change occurs inside the cell, the cell maintain same concentration of solutes both inside and outside the cell. Dynamic equilibrium is a type of equilibrium in which the reactants and products formed at the same rate and no change occurs inside the reaction. In the cell, homeostasis is responsible for maintaining equilibrium in the cell so no change occurs inside the cell.

An experiment was conducted to demonstrate the passage of glucose and starch across a selectively permeable membrane that allows monomers but not polymers to diffuse through.
Glucose and starch powders were mixed in 10 ml of water and poured into a cellulose bag, which was then sealed at both ends and placed in a beaker of water. After 30 minutes, the presence of glucose in the beaker was recorded with a testing paper, which turns green if glucose is present. The presence of starch was recorded by adding a few drops of iodine, which causes the solution to turn violet if starch is present.
A beaker filled with 100 milliliters of distilled water. A bag filled with 10 milliliters of water and a solution of 2 percent glucose and 2 percent starch is placed in the beaker of water.
Which statement best describes the expected result?
A) The testing paper will turn green and the solution will turn violet.
B) The testing paper will turn green and the solution will not turn violet.
C) The testing paper will not turn green and the solution will turn violet.
D) The testing paper will not turn green and the solution will not turn violet.
Answer:
B
Explanation:
because if you read the first paragraph, the membrane will only allow monomers not polymers. glucose is a monomer and starch is a polymer. so the membrane will only take glucose and the color for glucose therefore the color is only green.

Which population is most likely to have exponential growth?
O A. The dust mites living in a sofa that is often used and never
cleaned
B. The angelfish living in a coral reef where there are many sharks
C. The mice living in a meadow with plenty of predators and limited
food
D. The foxes living in a forest where they compete with other animals
for food
Answer:
A. The dust mites living in a sofa that is often used and never cleaned
Explanation:
Without the sofa being cleaned, the dust mites will never experience any predation or die off from humans and harsh cleaning chemicals. This will enable the population to increase exponentially, as opposed to the other options where the organisms are at risk for ample predation and starvation.
Exponential growth refers to the growth of organisms in an environment having unlimited resources. The organism grows exponentially or in a geometric fashion.
The dust mites living on the sofa that is often used and never cleaned.
The population has high chances of exponential growth will be:
1. Exponential growth is seen in the environment or surroundings where the resources are plentiful, and the number of organisms is dependent on those resources.
2. The dust mites living in the sofa that has never been cleaned will show exponential growth. Since the sofa is never cleaned, the mites have never faced any elimination by chemicals. The population will increase exponentially.
3. The other options have chances of competition, starvation, and predation that will not lead to the exponential growth of organisms.
Thus, the correct answer is Option A.
