Answer:
1. Black
2. Yellow
3. Bb (or BB)
4. bb
Explanation:
So they breed two black fur coats and get 75% black fur. This means that Bb is 75% too, making it black fur. The 25% (recessive) would be yellow.

A population of wolves migrate North in search of food. As the wolves travel they enter a region that has long, snowy Winters. This makes them better able to sneak up on prey.
A.) Give two reasons that the population is not a Hardy Weinberg equilibrium.
C.) How are the allele frequency change in the wolf population
Answer:
A, This is the case of selective pressure of environmental factors like snow, due to which favored the expression of the allele that formed white coat phenotype. This is not a Hardy-Weinberg principle, in which no selective pressure is applied. The relative frequencies of the alleles change in the gene pool, due to selective pressure, and the expressed alleles are often significant for survival in those conditions.
b,HW equilibrium means no selective pressures like the long, snowy winters selectively favoring the white coat phenotype over the other coat phenotypes. Selective pressures change the relative frequencies of the alleles in the gene pool. It also means the population does not have either immigration or emigration to change the ratios of alleles in the gene pool The Hardy-Weinberg principle of genetic equilibrium tells us what to expect when a sexually reproducing population has no selection pressure, no gene flow, no nonrandom mating, not even genetic drift.

Explanation:
How long will it take for 40.0 grams of Radium-226 (Ra-226) to decay to leave a total of 2.5 grams of Ra-226? Ra-226 has a half-life of 1600 years.
Answer:
6400 years
Explanation:
Given that;
N/No =(1/2)^t/t1/2
No = amount of radioactive material originally present
N = amount of radioactive material present at time t
t= time taken for N amount of radioactive material to remain
t1/2 = have life of the radioactive material
2.5/40 = (1/2)^t/1600
1/16 = (1/2)^t/1600
(1/2)^4 = (1/2)^t/1600
4 = t/1600
t = 4 * 1600
t = 6400 years
Mushroom rocks are formed by ___________________
Answer:
wind erosion
Explanation:
The rocks are deformed in a number of different ways: by erosion and weathering, glacial action, or from a sudden disturbance. Mushroom rocks are related to, but different from, yardang. A mushroom rock, rock pedestal, or gour is a typical mushroom-shaped landform that is formed by the action of wind erosion.
mushroom rocks are corn as fungi

Prokaryotes are better known as __________.

Why are green plants considered producers?
Green plants directly absorb sunlight to make energy.
Green plants contain chlorophyll.
Decomposers consume green plants.
Green plants are eaten by secondary consumers.
Answer:
The organisms that are capable of preparing their own food from simple inorganic substances like carbon dioxide and water by using sunlight energy in the presence of chlorophyll are called producers. The green plants synthesize their own food through the process of photosynthesis and thus are called the producers.plants produce food for themselves, they are known as producers.When a person doesn't get enough sleep, their immune system:

How does thermal energy affect the earth's layers?
Answer:
The thermal energy of the Earth remains from its formation and is continuously generated from radioactive decay of long-lived radionuclides in the Earths interior. The deeper the Earth layers the higher the temperature with the geothermal gradient of temperatures through the Earth’s crust on average as high as 25–30°C/km.
Explanation:
The thermal energy affect the earth's layers by forming a thermal gradient.
Thermal energy of the Earth:
Deep inside the earth the thermal energy is generated by the radioactive decay of long-lived radionuclides.
This creates a thermal gradient from core to surface of the earth. The temperature of the core is highest, then the manle is semi-solid or liquid.
The crust of the earth is solid and have relatively less temperature,
Therefore, the thermal energy affect the earth's layers by forming a thermal gradient.

What happens to a cell in a hypertonic solution
Answer:
If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
