I will mark brainliest!! THANK YOU! Students are discussing differentiation of cells in an organism. Which student has to most accurate description of differentiation?
Answer:
Student 2
Explanation:
I think it is student 2 because differentiation is the dividing and changing of embryonic stem cells into cells that are specialized in structure and function. Some stem cells form liver cells, some heart cells, muscle cells.
Answer: Student 1: differentiation occurs during reproduction.
Explanation:
The process of cell differentiation starts with the fertilization of the female egg. As soon as the egg is fertilized, cell multiplication is initiated resulting in the formation of a sphere of cells known as the blastocyst.

does coal releases carbon dioxide into the atmosphere?
Answer:
yes
Explanation:
Coal is an important source of energy in the United States, and the Nation's reliance on this fossil fuel for electricity generation is growing. The combustion of coal, however, adds a significant amount of carbon dioxide to the atmosphere per unit of heat energy, more than does the combustion of other fossil fuels
What does the mnemonic device "Did King Philip Come Over For Good Spaghetti" mean, in terms of Taxonomy and Classification?
Answer:
See the answer below
Explanation:
The mnemonic is used to represent the major taxonomic categories used in classifying living organisms. Each of the words in the sentence (except 'Did') represents the categories as follows:
King - Kingdom
Philip - Phylum
Come - Class
Over - Order
For - Family
Good - Genus
Spaghetti - Species
The kingdom represents the highest category of classifying living organisms. Each organism has to belong to one of the 5 major kingdoms - monera, protista, fungi, plant, or animal. Phylum comes after the kingdom, followed by class, order, family, genus, and species. The lower the category, the lower and more similar the organisms they contain.
The island spotted skunk and the island fox are both predators of the island
deer mouse (the prey). How could these two predators establish different
niches and still prey upon island deer mice? *
A. the island spotted skunk hunts at different times than the island fox
B. the island spotted skunk hunts in the same area as the island fox
C. the island fox eats only cherries instead of deer mice
D. the island deer mice swim to a different island to avoid predators
Answer:
I think the answer is A because if they hunt at the same time they will kill themselves
What do the arrows indicate?
Air moves in a direction that creates land breezes.
Air above land warms faster than air above water.
Air blows over long distances in a continual straight path.
Air pressure remains the same while cycling over land and water.
Answer: Air moves in a direction that creates land breezes.
Explanation:
The arrows indicate is air moves in a direction that creates land breezes. So, the correct option is A.
What are Land breezes?Due to the difference in temperature of land and sea, land breezes are those winds which blow from land to sea at night.
The Sun heats both land and sea during the day, but land heats up more quickly than water. As a result, an area of low pressure is generated as the air above the ground is heated and rises. As a result, cold sea air fills the space and creates a sea breeze that blows from sea to land.
The opposite happens at night. The air over the land becomes cooler and denser because the land cools faster than the sea. As a result, high pressure develops over the land. Then a land breeze is generated, which flows from land to sea by cold and dense air moving from land to sea.
So, the correct option is A.

What shape is used in Model 1 to represent an A antigen?
Answer: Type A red blood cells have a-antigens, while type O has none.
Explanation:
As precipitation infiltrates into the subsurface soil, it generally forms an unsaturated zone and a saturated zone. In the unsaturated zone, the voids-that is, the spaces between grains of gravel, sand, silt, clay and cracks within rocks-contain both air and water. Although a lot of water can be present in the unsaturated zone: why can't this water be pumped by wells
A) Soils, like clay, absorb water quickly
B) Sinkholes collect water above the water table.
C) Land with no slope lets water runoff at a fast rate.
D) If its not any of the other its this
Answer:
Water in the soil zone is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere

Select all the statements that are consistent with the Endosymbiont Theory Select all the statements that are consistent with the Endosymbiont Theory Mitochondria and chloroplasts are semiautonomous organelles, with many similarities to bacteria. Mitochondria resemble bacteria in size and shape and are surrounded by double membranes, the inner of which has bacterial-type lipids. Chloroplasts have circular DNA molecules. Mitochondria rRNA sequences, ribosome size, sensitivities to inhibitors of RNA and protein synthesis, and type of protein factors used in protein synthesis are all similar to bacteria.
Answer:
Mitochondria and chloroplasts are semiautonomous organelles, with many similarities to bacteria.Mitochondria resemble bacteria in size and shape and are surrounded by double membranes, the inner of which has bacterial-type lipids. Chloroplasts have circular DNA molecules.Explanation:
The endosymbiotic theory essentially states that some organules of the eukaryotic cells, such as mitochondria and chloroplasts, were once free-living bacteria. Probably, these organisms must have been phagocytized, but not digested by another cell. On the contrary, these bacteria were able to adapt to their host in such a way that the two cells established a dependent relationship with each other.
Due to its similarities to other free-living bacteria, it has been speculated that chloroplasts must derivate from cyanobacteria (they both absorb sunlight and store the energy in ATP, and produce organic molecules) and that mitochondria must derivate from rickettsias (they produce ATP in the same manner, by using the Krebs Cycle and Oxidative Phosphorylation).
From the phagocytosis moment, these two cells created a new bond between them of mutual benefit, becoming dependant on each other, up to the point that they would not be able to survive without the other one.
This theory is supported by a few characteristics of the chloroplasts and mitochondria that suggest that they once were a free cell. For example,
Both organelles present their own genetic material. This DNI is independent of the DNA of the cells, is bi-catenary and circular, identical to the DNA of the bacteria, and very different from the one of the eukaryotic cells. These organelles divide by binary fission and not by mitosis, and are capable of synthesizing their own ribosomes and organelles. Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the membrane of bacterias, while the external membrane looks like the eukaryotic one.In fact, in this internal membrane are placed the energy centers, exactly as it occurs in bacterias membrane.
Finally, the sizes of the organelles are similar to the size of some procaryotes.What is the next stage after the body plan is established?
Answer:
Origin. 20 out of the 36 body plans originated in the Cambrian period, in the "Cambrian explosion", However, complete body plans of many phyla emerged much later, in the Palaeozoic or beyond.

can someone give me good evidence please i will give you brainliest
Answer:
you can get evidence by observing how people have different traits from their parents, like one sibling can look different than they other sibling, they can get traits from older generations, like you can have a family that has black hair or dark brown and one of their kids got light brown hair because that was passed down or skipped through a generation.
Explanation:
Genes carry the codes that tell the body how to form itself.
True or False
I put a picture does anyone know the answer to that
Answer:
C- All members of the population are genetically similar and are less likely to survive environmental change.
Explanation:
In asexual reproduction, there is no diversity since the offspring gets all their genes from their parent. That being said, they won't be able to inherit traits that would help them survive in a changing environment since there is no diversity of traits that would help them in other environments.

Select the statement that does not correctly describe the circulation of blood.
1)blood flows in two loops.
2)the ventricles contract simultaneously to pump blood outside the heart.
3)blood flows simultaneously into the atria.
4)the right side of the heart receives
blood and the left side pumps blood.
Answer and I will give you brainiliest
sorry im not sure this is correct but i think the one that is incorrect is
4) the right side of the heart receivesblood and the left side pumps blood.i will put the explanation just incase you want to choose the answer by yourself after knowing it. I hope you read this too..
Explanation1)Blood flows in two loops
This one is already correct if it happens in human heart circulatory system. Human's heart beat in two loops and this is really useful because of enough pressure to pump blood to the body. This two loops name is double circulatory system.However fish has single circulatory system where they only pump blood once. So this one also can be wrong but if the answer only one, this one can pass.2)the ventricles contract simultaneously to pump blood outside the heart.[✓]
This one already correct, the heart pump blood to the body through aorta and to the lungs through pulmonary artery.3)blood flows simultaneously into the atria.
This one also correct, because the blood come to the atria first to go to the left ventricle. Both of left and right ventricles are working simultaneously.4)the right side of the heart receives
blood and the left side pumps blood.
This one can be correct but also wrong. I choose this one wrong because there's no more explanation in this statement. The right side of heart can also pumps blood and left side of heart also can receives blood.The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs and also The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.Note for moderators that read this#Moderators please don't be mean, dont delete my answers just for approval from your senior or just to get the biggest moderation daily rank.
