A population of birds is blown by a storm to an island off the mainland.
The island has very few trees, and the bird population on the island
develops new nesting behaviors. Mainland birds nest in trees, island birds
nest on the ground. After a long period of time, the island birds are
reunited with the mainland birds, it is observed that the two populations
can no longer interbreed. This is an example of: *
Behavioral isolation
Geographical isolation
Nonrandom mating
All of these
How do T-cells help with destroying viruses?
Answer:T-cells are a type of white blood cell that work with macrophages. Unlike macrophages that can attack any invading cell or virus, each T-cell can fight only one type of virus. You might think this means macrophages are stronger than T-cells, but they aren’t. Instead, T-cells are like a special forces unit that fights only one kind of virus that might be attacking your body.The T-cell receptor fits with its antigen like a complex key. When the perfectly shaped virus antigen on an infected cell fits into the Killer T-cell receptor, the T-cell releases perforin and cytotoxins. ... Cytotoxins go directly inside the cell through this pore, destroying it and any viruses inside.

Were you able to identify a cell undergoing cytokinesis in an onion cell? Explain.
Answer:
Mitosis and meiosis are different types of cell division, and although they are first ... One could be forgiven for the assumption that the classic 'onion root tip squash' ... magnification using the eyepiece and objective lens, you will need to be able to ... about how the cells were being used, and had been given no explanation, ...
Explanation:
The cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.
Mitosis is a type of somatic cell division that has four main steps (prophase, metaphase, telophase and anaphase) followed by cytokinesis. Moreover, cytokinesis is the division of the cytoplasm to form two daughter cells.The cell plate is a transient compartment that grows between daughter cells. Once cytokinesis is completed, the cell plate gives rise to the cell wall.
In conclusion, the cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.

Write a set of directions for a red blood cell to deliver oxygen to the brain. Lungs heart-brain aorta arteries veins
Answer: How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.OK Our typical red cell passes from the capillary into the venules, and then into veins. It flows back to the right side of the heart, completing the second loop of its circuit [music out]. As we saw, it then travels back to the lungs.The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

Is methemoglobinemia recessive or dominate? Provide examples to back up your answer
Answer:
recessive
Explanation:
The inheritance pattern of the congenital enzyme deficiency form of the disease is autosomal recessive. Hb M is inherited in an autosomal dominant pattern. There is no association between sex and the frequency of congenital methemoglobinemia.
Methemoglobinemia is an autosomal recessive congenital disorder. It means that both copies of the gene are found to be recessive in order to express a phenotype.
What do you mean by the Dominant trait?The Dominant trait may be defined as a form of trait which governs by the presence of at least one dominant copy of that gene.
Methemoglobinemia may be defined as a blood disorder in which very little amount of oxygen is delivered to your cells. Cells may feel the scarcity of oxygen.
If an individual is affected by this disorder, both the copies of its gene are found in a recessive form in order to mask the effect of a dominant copy.
Therefore, it is well described above.

Explanation:
Forensic DNA examination found the earliest known ancestors of modern
dogs occurred
Explanation:
By analyzing the DNA of two prehistoric dogs from Germany, an international research team has determined that their genomes were the probable ancestors of modern European dogs. The finding suggests a single domestication event of modern dogs from a population of gray wolves that occurred between 20,000 and 40,000 years ago.
what would happen to the earth the moon and the sun if there was no gravity acting on these objects in space?
Answer:
Without the force of gravity from the Earth, it would just float away into space. This mix of velocity and distance from the Earth allows the Moon to always be in balance between fall and escape. If it was faster, it would escape; any slower and it would fall!

Why do deserts tend to form on land at latitudes of 20-30 degrees north and south?
Answer:
Deserts can form even on tropical coasts beside cold ocean currents, such as the west coast of South America. The currents cool the air, which then rises and warms as it moves over land, drawing up moisture that is later precipitated as the air moves farther inland.

What does a model of the carbon cycle show?
A. The amount of Earth’s carbon is constant.
B. The amount of Earth’s carbon cannot be determined.
C. The amount of Earth’s carbon decreases.
D. The amount of Earth’s carbon increases.
I think its A
Answer:
Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth. This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year.
The model of the carbon cycle determines the amount of earth's carbon is constant. Thus, option A is correct.
Carbon is the element that is responsible for the major life forms on earth. The conversion of carbon in varying life forms and the reservoir is given by the carbon cycle.
What is the effect of the carbon cycle on the amount of carbon?The carbon cycle is operated for the analysis of the conversion of the carbon in different states and life forms in the earth.
The conversion results in the change in the state of the carbon and its concentration in different constituents.
The earth is the reserved closed system and is consisted of a fixed amount of elements.
Thus, the amount of carbon in the earth is constant in the model of the carbon cycle. Thus, option A is correct.

pls help!!! osmosis help needed!!
Answer:
1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic
Explanation:
1. Given the image, it shows there is 10% glucose outside the cell.
2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)
3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.
2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water outside the cell than in. So, yes, osmosis will occur.
3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).
3. The cell will swell, since water is getting moved in.
6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always swell, as water moves into it.
Hopes this helps!^^ I tried the best I could at explaining.
