Answer:

False

Explanation:  Chemical changes are changes that occur when one substance is turned into another substance. The particles of one substance are rearranged to form a new substance.

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.

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.

2nd largest on the worls

Answer:

2nd largest, Russia is the biggo boi

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.

C, ?? I don’t know

Explanation:

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.

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.

Explanation:

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.

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.

Advantages:

The plant is an integral member of the regional desert ecosystem and native pollinators such as hummingbirds and carpenter bees consume ocotillo nectar for nutrients. The hummingbird and the ocotillo have an important plant-pollinator relationship, as the hummingbird relies upon the flowers for a nectar source.

The relationship between Ocotillo and Hummingbird is an example of a mutualistic relationship, which means that both species benefit from each other's presence.

The advantages and disadvantages of this relationship can be described as follows:

Advantages:

Ocotillo provides a source of nectar for hummingbirds, which is an important source of energy for their high metabolic rate.

Hummingbirds are efficient pollinators of Ocotillo flowers, which helps to ensure their reproduction and genetic diversity.

Ocotillo provides a nesting site for hummingbirds, where they can raise their young in safety from predators.

Disadvantages:

The relationship between Ocotillo and hummingbirds is specific and may not be beneficial to other species of plants or animals.

Ocotillo is adapted to living in arid environments and may not provide a suitable habitat for some other species of birds or animals.

If the population of either Ocotillo or hummingbirds were to decline significantly, it could affect the survival of the other species in the mutualistic relationship.

Overall, the advantages of the Ocotillo-Hummingbird relationship outweigh the disadvantages, and this mutualistic relationship is an important part of the ecosystem in which they both live.
