In around 50 years, the peppered moth population changed from nearly all light wings to nearly all dark wings. Explain exactly how the moth population changed (evolved).
Answer:
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. ... Later, when pollution was reduced, the light-coloured form again predominated.

Complete el cuadro de Punnett que muestra un cruce entre un hombre que es heterocigoto para el tipo de sangre B y una mujer que es heterocigota para el tipo de sangre A.
Answer:
F1) 1/4 = 25% de la porgenie será AB, IAIB
1/4 = 25% de la progenie será heterocigota para el tipo A, IAi
1/4 = 25% de la progenie será heterocigota para el gruo B, IBi
1/4 = 25% de la progenie será homocigota recesiva, ii
Explanation:
El gen I determina el tipo de sangre de una persona. Es un gen dialelico que muestra alelo dominante I y recesivo I. En personas de tipo A, los alelos son IA dominante, i recesivo.En personas de tipo B, los alelos son IB dominante, i recesivoIA e IB son codomiantes entre si, lo que signofica que hay un tercer fenotypo IAIB, expresando ambos tipos de sangre juntos. El alelo i es recesivo siempre.Genotipo A:

What is the difference between a specialized plant cell and a specialized animal cell?
Answer:
Explanation:
Major structural differences between a plant and an animal cell include: Plant cells have a cell wall, but animals cells do not. Chloroplasts enable plants to perform photosynthesis to make food. Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles if any are present.
Your best friend is concerned about a mole on her arm. Knowing that you are taking a biology class she comes to you and asks for your opinion. You take a sample of her mole and view it under a microscope. While counting a selection of 300 cells, you notice that 87 cells are actively undergoing mitosis. Should your friend be concerned?
Answer:
She should consult a dermatologist immediately.
Explanation:
When doing preemptive diagnosis of a mole, one should compute the Mitotic Rate (MR) - and the MR reported in the question is way above the highest category "greater than 4 per square millimeter" (to compare. there's around 2000 cells per sqmm of skin, so we're at over 500 per square millimeter).

During the daytime, the land warms up faster than water causing the air above the land to be less dense and rise into the atmosphere. What will this cause?
Answer:
The faster warming of the earth than water that causes the air above the land to be less dense and rise into the atmosphere will result in Sea breezes
Explanation:
Land and Sea breezes are phenomena which occur through the heat transfer process of convection.
Sea breezes occur mostly during the hot summer afternoons because of the unequal heating of land and water. During the day, both the land and sea receives equal amounts of heat from the sun, but, the land surface heats up faster than the water surface. Therefore, the air above the land becomes heated up more and is warmer than the air above the ocean. The air above the land to become less dense and as result, the warm air rises into the atmosphere. However, at the ocean surface, the air above is is colder and hence, denser than the warm air over the land surface. Thus, the air pressure at the ocean surface is greater than at the earth's surface. As the warm air over the land is rising, a convection current is set up and the cooler air over the ocean flows with the aid of the wind and replaces the warm air from earth's surface. This is known as sea breeze.

dose DNA have cells
i need to know for a assingment
Answer and Explanation:
Cells are made of DNA (Deoxyribonucleic Acid).
They provide the genetic instructions for making and forming a cell.
The DNA is found inside the nucleus of the cell.
Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome
DNA do NOT have cells, but cells DO have DNA.

O large intestine and small intestine
O liver and kidney
O tubules and ureters
Answer:
Its A skin and anus
(just did test)
Explanation:
The skin and the Anus are sites where waste products are released from the body but not where they are produced.
Which process of the human body eliminates the waste products?Excretion is the biological process through which any unwanted or waste products are eliminated from the body.
Large and small intestines produce waste products that are not completely digested by the stomach. The liver and kidney are also the sites of waste products like the removal of carbon dioxide and synthesis of urine respectively.
Therefore, the skin and the Anus are sites where waste products are released from the body but not where they are produced.
