Scientists have evidence that meteorites have come from which option of locations?
Step2247 [10]

Mars and Moon are the locations from which meteorites would come.

Option (c);

<u>EXPLANATION: </u>

  • The meteorites found on Earth look like martian crystal rocks.
  • These might be first ejected into space during a collision of an asteroidal object with Moon or Mars and then it got into the Earth orbit because of the force produced during the collision.
  • There are around seventy meteorites recognised to have come from the planet Mars till up to the present date.
  • There are three types of meteorites such as Martian meteorites and a sample of two lunar meteorites.
  • To identify the origin of the meteorite, the scientist tries to identify the type of rock followed by analysing the chemical composition and then try to identify its age.

Albinism in humans is caused by homozygosity for mutant recessive alleles of the tyr gene, which is located on chromosome 11. al
yanalaym [24]
Exactly 989527/1048576, or approximately 94.37%  
Since each trait is carried on a different chromosome, the two traits are independent of each other. Since both parents are heterozygous for the trait, each parent can contribute 1 of a possible 4 combinations of the alleles. So there are 16 possible offspring. I'll use "a", "A", "b", "B" to represent each allele and the possible children are aabb, aabB, aaBb, aaBB, aAbb, aAbB, aABb, aABB, Aabb, AabB, AaBb, AaBB, AAbb, AAbB, AABb, and AABB 
Of the above 16 possibilities, there are 7 that are homozygous in an undesired traint and 9 that don't exhibit the undesired trait. So let's first calculate the probability of "what are the chances that all 5 children not exhibiting an undesired trait?" and then subtract that result from 1. So 
1-(9/16)^5 = 1 - 59049/1048576 = 989527/1048576 which is approximately 0.943686485 = 94.3686485%  
So the answer is exactly 989527/1048576, or approximately 94.37%

Compare and contrast genetic engineering to the process of natural selection select all statements that are are
alisha [4.7K]

Genetic engineering is due to the human selection of desired phenotypes, whereas natural selection is a slow process of differential survival and reproduction.

<h3>What does natural selection mean?</h3>

According to the evolution theory, natural selection is a slow process of differential survival of the fittest organisms in a given environment.

Conversely, genetic engineering refers to the molecular biology techniques used in the laboratory to produce organisms expressing desired phenotypes.

In conclusion, genetic engineering is based on human molecular biology techniques, whereas natural selection refers to differential survival and reproduction in nature.

What is a gene? a single strand of DNA. the fundamental unit of heredity. a single nucleotide. the fundamental unit of DNA
const2013 [10]

Answer:

the fundamental unit of heredity

Explanation:

DNA is a double stranded helix structure. Each strand is made up of a string of nucleotides.

A gene is a region of DNA, usually tens of thousands of nucleotides long. At the simplest level, one gene encodes for one trait. Therefore, the gene can be described as the fundamental unit of heredity.

Genes work by coding for specific proteins, which carry out essentially all the functions in the cell.
