Gene expression controls differentiation of cells. Details about differentiation can be found below.
What is cell differentiation?Cell differentiation is a cellular process in which the cells of multicellular organisms advance in organization and acquire special organs for specific purposes.
Cell differentiation is what forms specific cells that are adapted to specific roles in multicellular organisms.
However, this process of differentiation is as a result of the expression of genes at different times, since, all cells of an organism contains the same genes.

Hich one of the substances is not transported by the human circulatory system?(1 point) a) water b) digested food c) carbon dioxide d) undigested food 5
Answer:
D
Explanation:
Undigested food is not transported by the human circulatory system. Hence, option D is correct.
What is the circulatory system?The system which contains the heart, blood vessels, and blood is called the circulatory system. There are three types of circulation that take place in the body and that is systemic, coronary, and pulmonary circulation.
The heart is a muscular organ, that pumps blood in the body. Blood vessels carry blood from the heart to tissues or tissues to the heart. Blood is a fluid, which flows inside the blood vessels.
The main function of this system is to transport water, nutrients, digested food, oxygen, carbon-di-oxide, minerals, and excretory products in the entire body through blood. It does not transport undigested food. Hence, option D is correct.

The major pathway of communication between the right and left hemispheres is the.
Answer:
corpus callosum.
..............
Answer:
Corpus callosum
Explanation:
Actually, the left and right brain hemispheres may communicate with one another because to a thick bundle of nerves called the corpus callosum (Latin for "difficult body"). The corpus callosum, which is divided into several sub regions, connects various sections of the hemispheres. The corpus callosum is subdivided into the rostrum, genu, body, and splenium from anterior (front) to posterior (back). The brain's left and right frontal lobes are linked by the rostrum and genu. The hemispheres of the temporal and occipital lobes are connected by the body and spleen.
With over 200 million axons, the corpus callosum is the brain's biggest fiber bundle. It is made up of tracts of white matter fibers called commissural fibers. It has a role in several bodily processes, including the communication between the:
Cerebral hemispheres.Motion of the eye and vision.keeping the right balance of arousal and focus.The localization of touch.The different parts of our visual field, which independently process pictures in each hemisphere, are combined by the corpus callosum, which plays a crucial role in vision. By connecting the language centers of the brain with the visual cortex, it also enables us to recognize the objects we view. In order for humans to find touch, the corpus callosum also transmits tactile information—which is processed in the parietal lobes—between the two hemispheres of the brain.

Describe the steps involved in the release of neurotransmitter into a synaptic cleft to bind to its receptor.
Answer:
Polarization and depolarization
Explanation:
The transfer of signal happens by the exchange of sodium and potassium ions in and out of the cell membrane of neuron.
Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain proteins that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell.
Based on this information, what type of transport is used for glucose in blood and intestinal cells?
A.
Both blood and intestinal cells take in glucose by passive transport.
B.
Blood cells take in glucose by active transport and intestinal cells take in glucose by passive transport.
C.
Blood cells take in glucose by passive transport and intestinal cells take in glucose by active transport.
D.
Both blood and intestinal cells take in glucose by active transport.
Both blood and intestinal cells take in glucose by passive transport. Thus, the correct option is B.
What is facilitated diffusion?A transport protein found in the plasma membrane facilitates diffusion, which is the passive movement of things like biological molecules or ions across a plasma membrane. Chemical energy is neither utilized nor required because compounds are moved from higher to lower concentrations.
Glucose is absorbed by the mechanisms of facilitated diffusion or passive transport across the membrane of red blood cells. The sugar glucose is transferred by active transport from the gut into intestinal epithelial cells.

what is the significance of diffusion and osmosis in living organism ?give one example in support of your answer
Answer:
Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).
Examples of where diffusion is important;
In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.
Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.

Answer:
natural selection ; homologous
The population of birds with large beaks will increase on the island (1st listed) ; The trait for large beaks will be passed on to future generations through natural selection. (3rd listed)
B) 80 /200
Explanation:
Giraffes evolved over many generations to have long necks. Giraffes that had longer necks were more likely to survive than giraffes with shorter necks because they had better access to food. This is an example of natural selection / survival of the fittest.
(the "fittest" [most beneficial/practical] trait is surviving and getting "selected" by nature)
Giraffes are also vertebrates, like humans. In fact, despite their different neck sizes, humans and giraffes have exactly seven vertebrae bones in their neck. This similarity suggests human and giraffe necks are homologous [structures]

...' What are two ways the decrease in seed availability will affect the population of birds on the island?'
The population of birds with large beaks will increase on the island.
[This is the concept of natural selection / survival of the fittest, they have the most abundant resource [because they are able to eat what is abundant on the island, compared to smaller birds that have a larger decrease in food availability] ]
The trait for large beaks will be passed on to future generations through natural selection.
[If these birds / and this trait survive, they will be able to have offspring [future generations]. Birds with a low survival percentage will be less successful in mating, and will likely not produce the same quantity of offspring that will carry on their traits to future generations.]

frequency of an allele:
population: 100
frequency recessive [homozygous bc 2 same recessive alleles]: 25 (tt)
frequency dominant homozygous: 45 (TT)
frequency heterozygous dominant: 30 (Tt)
total alleles: 100 [our population] times 2
100 · 2 = 200
total alleles: 200
number of times we have [dominant] T:
30 from each heterozygous dominant (Tt)
2 · 45 (TT has two T's) = 90 from homozygous dominant
30 + 90 = 120
number of times we have [recessive] t :
30 from each heterozygous dominant (Tt)
2 · 25 (tt has two t's) = 50 from each homozygous recessive
30 + 50 = 80
So, we know that the frequency of recessive allele [t] is 80 / 200
[80 out of 200]
So, option B) 80 / 200 is correct
(this = 0.4)
(and dominant [T] is 120 / 200; I say this to show that recessive frequency and dominant frequency are calculated the same way!!)
(this = 0.6)
