what is somatic cell ?Somatic cells are involve in the growth and development of an organism required for repair and regeneration
Somatic cells participate in mitosis and contain the same set of chromosomes, these cells have a diploid set of chromosomes as compared to gametes produced by meiosis and have a haploid set of chromosomes
Somatic cells undergo mutation frequently as compared to germ cells, used for cloning by which an identical clone of an individual is produced
Somatic cell nuclear transfer is one such process where the nucleus of a somatic cell is transferred to an ovum cell. Somatic cells are used to conserve genetic information of animals.

If more individuals are born with the advantageous trait in each generation, over time what do you predict will happen to the percentage (%) of the alleles (gene variety) that code for this trait in the population?
Answer:
The percentage (%) of the alleles that code for this trait in the population will increase, as more individuals are born with the trait.
Explanation:
The more individuals get born expressing the trait, the higher its frequency gets in the population. By generation, there are more individuals carrying the allele for the advantageous trait. These individuals reproduce and increase the probabilities of the progeny to inherit the mentioned allele. When this sequence keeps occurring in the population over many generations, the allele percentage will increase. On the other hand, the other allele or alleles will decrease. Probably, if there are no changes that might influence or affect this pattern, the alleles for the advantageous trait will fixate, while the other allele might get lost.

Why would horses from North America settle in southern Russia?
Are wild horses truly “wild,” as an indigenous species in North America, or are they “feral weeds”—barnyard escapees, far removed genetically from their prehistoric ancestors? The question at hand is, therefore, whether or not modern horses, Equus caballus, should be considered native wildlife.
The question is legitimate, and the answer important. In North America, the wild horse is often labeled as a non-native, or even an exotic species, by most federal or state agencies dealing with wildlife management, such as the National Park Service, US Fish and Wildlife Service, and the Bureau of Land Management. The legal mandate for many of these agencies is to protect native wildlife and prevent non-native species from causing harmful effects on the general ecology of the land. Thus, management is often directed at total eradication, or at least minimal numbers. If the idea that wild horses were, indeed, native wildlife, a great many current management approaches might be compromised. Thus, the rationale for examining this proposition, that the horse is a native or non-native species, is significant.
The genus Equus, which includes modern horses, zebras, and asses, is the only surviving genus in a once diverse family of horses that included 27 genera. The precise date of origin for the genus Equus is unknown, but evidence documents the dispersal of Equus from North America to Eurasia approximately 2–3 million years ago and a possible origin at about 3.4–3.9 million years ago. Following this original emigration, several extinctions occurred in North America, with additional migrations to Asia (presumably across the Bering Land Bridge), and return migrations back to North America, over time. The last North American extinction probably occurred between 13,000 and 11,000 years ago (Fazio 1995), although more recent extinctions for horses have been suggested. Dr. Ross MacPhee, Curator of Mammalogy at the American Museum of Natural History, and colleagues, have dated the existence of woolly mammoths and horses in North America to as recent as 7,600 years ago. Had it not been for previous westward migration, over the 2 Bering Land Bridge, into northwestern Russia (Siberia) and Asia, the horse would have faced complete extinction. However, Equus survived and spread to all continents of the globe, except Australia and Antarctica.
In 1493, on Columbus’ second voyage to the Americas, Spanish horses, representing E. caballus, were brought back to North America, first in the Virgin Islands, and, in 1519, they were reintroduced on the continent, in modern-day Mexico, from where they radiated throughout the American Great Plains, after escape from their owners or by pilfering (Fazio 1995).
Critics of the idea that the North American wild horse is a native animal, using only selected paleontological data, assert that the species, E. caballus (or the caballoid horse), which was introduced in 1519, was a different species from that which disappeared between 13,000–11,000 years before. Herein lies the crux of the debate. However, neither paleontological opinion nor modern molecular genetics support the contention that the modern horse in North America is non-native.
Equus, a monophyletic taxon, is first represented in the North American fossil record about four million years ago by E. simplicidens, and this species is directly ancestral to later Blancan species about three million years ago (Azaroli and Voorhies 1990). Azzaroli (1992) believed, again on the basis of fossil records, that E. simplicidens gave rise to the late Pliocene E. Idahoensis, and that species, in turn, gave rise to the first caballoid horses two million years ago in North America. Some migrated to Asia about one million years ago, while others, such as E. niobrarensis, remained in North America.
If the yellow allele is dominant (Y) and the green allele is recessive (y), what are the possible genotypes of a green offspring?
Answer:
yy
Explanation:
it can only be yy because you need 2 recessive genes to show a recessive trait.
A plant with Yy genes could pass the recessive genes on, but would still show the dominant trait.
The possible genotype of the green offspring is yy, i.e., recessive one and will express only in absence of dominant allele.
What is genotype?In a broad sense, the word "genotype" refers to an organism's genetic makeup; in other words, it describes an organism's entire set of genes.
In a narrower sense, the term can refer to the alleles, or variant forms of a gene, that an organism carries.
A genotype is a classification of the type of variant found at a specific location (i.e., a locus) in the genome.
Symbols can be used to represent it. For example, the letters BB, Bb, bb could be used to represent a specific variant in a gene.
In the given scenario, Y is dominant allele which will express in combination with y means the recessive one.
Thus, for expressing the green allele, it should be yy.

during a luner eclipse the earth comes between the sun and the sun and the moon blockimg the sunlight falling on the moon.
An unidentified plant produces spores, has many cells, but does not have true leaves. What plant is it?
A. liverwort
В. fern
C. gymnosperm
D. angiosperm
An unidentified plant produces spores, has many cells, but does not have true leaves. It is a fern or the angiosperms. Thus, option C is correct.
What are angiosperms?Angiosperms, that are also known as flowering plants, have “seeds” that are sealed off within an “ovary”, while gymnosperms do not have fruits or flowers and have uncovered seeds on the surface of leaves. Seeds of gymnosperms are often arranged as “cones”.
The features and characteristics that distinguish angiosperms from gymnosperms are fruits, flowers, and “endosperm” in the seeds. Examples of “Angiosperms” are “monocots” like orchids, lilies, agaves, grasses and dicots like, peas, roses, sunflowers, maples and oaks. “Gymnosperm” examples include “non-flowering evergreen” trees like pine, fir and spruce.
Therefore,An unidentified plant produces spores, has many cells, but does not have true leaves. It is a fern or the angiosperms. Thus, option C is correct.

Which of the following examples come from renewable natural resources
Answer:
Milk, Leather, Paper, Cardboard
Explanation:
Milk, leather, paper, and cardboard all come from natural resources for the largest part:
Milk - Cows
Leather - Animal hide
Paper - Trees
Cardboard - Recycled paper
All of the mentioned are renewable because cows can breed, hide can be found on many animals, trees easily grow everywhere, and cardboard is made from recycled paper (which comes from trees).
Uranium, tin, iron, plastic, steel, and gold aren't renewable and (most of them) do not come from natural resources. Uranium is rare and only found in a limited source around the world, as well as other metals (tin, iron, steel, gold). As for plastic? Plastic is not natural nor renewable because it's created by man. All of the above mentioned (besides the answer) also takes thousands of millions of years to degrade naturally.

Answer:
So that in a guinea pig cross in the offspring the recessive trait —long hair— can be observed in 25%, the most probable genotype of the parents is heterozygous Ss.
Explanation:
In guinea pigs, for the characteristic hair length, short hair is the dominant allele and long hair is the recessive one.
In order for 25% of the offspring to express the recessive characteristic, the parents must have a recessive genotype, which can be seen in Punnett's Square:
P: Ss X Ss
Alleles S s
S SS Ss
s Ss ss
Where the offspring is:
50% Ss with short hair phenotype 25% SS with short hair phenotype 25% ss whose phenotype would be long hair.According to this, heterozygous parents for the characteristic long hair in guinea pigs have a 25% chance of having offspring with long hair.
