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.

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.A chemical which consists of just one kind of atom is always:

Explanation:
What will happen to this cell?
A) it will shrink
B) nothing
C) it will explode
The cell shown in the image is placed in a solution of 0.5 M whereas the internal concentration of the cell is 0.1 M, hence the solution is hypertonic and the cell will shrink.
The correct option is A.
What is a hypertonic solution?A hypertonic solution is a solution with a higher concentration of solutes (e.g. salt, sugar, or other molecules) compared to another solution.
When a cell is placed in a hypertonic solution, water molecules will move out of the cell and into the surrounding solution, which can cause the cell to shrink or even collapse. This is because the concentration of solutes inside the cell is lower than that of the hypertonic solution, so water diffuses out of the cell in an attempt to balance the concentration on both sides of the cell membrane.

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.

Black coat is dominant over white coat in guinea pigs. A homo-zygous black pig is mated with another homo-zygous black pig.
What are the genotypes of the parents?
Question 5 options:
bb and bb
BB and bb
Bb and Bb
BB and BB
Answer:
BB and BB
Explanation:
BB is a homo-zygous allele and both of the parent guinea pigs are homo-zygous.
A black coat is dominant over a white coat in guinea pigs. The genotypes of the parents are BB and BB. The correct option is d.
What is a genotype?The terms genotype and phenotype relate to the individual's alleles and the observable traits that are generated from the genotype and determined by the dominance of the alleles, respectively.
For black coat = B
For White coat = b
A homozygous black pig is mated with another homozygous black pig. Homozygous means only one character will be shown in the genotype, that is the dominant and the dominant trait is black, B so, the genotype will be BB and BB. Recessive traits are hidden that do not show, and that is also black.
Therefore, the correct option is d. BB and BB.
