16. If the amount of quanine in a DNA molecule is 32%, the amount of thymine would be

Biology
1 answer:
shepuryov [24]3 years ago
4 0

Answer:

The <em>answer </em>is option A i.e "32%". According to Chargraff's rule, Number of purine (adenine+guanine) = Number of pyrimidine (cytosine+thymine). Hence, the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.

Evolution is one of the unifying themes of biology. Evolution involves change in the frequencies of alleles in a population. For
lapo4ka [179]

A Mutation occurring in the population will change the allelic ratio.

<h3>What is evolution?</h3>

Evolution refers to the changes that occurs in organisms over a long period of time such that those changes results in new species better adapted to their environment and having higher specialization.

One of the factors of evolution is mutation.

According to the Hardy-Weinberg principle, the allele and genotype frequencies of a population of organism in equilibrium will remain constant in the absence of evolutionary influences.

Therefore, if a mutation occurs in the population, the allelic ratio will change.

How are binary fission and mitosis similar?
daser333 [38]

Answer:

Both binary fission and mitosis produce genetically identical daughter cells.

Explanation:

The process in which new cells are made in order to grow, replenish (repair), and reproduce is called cell division . The three main types of cell division are binary fission, mitosis, and meiosis. In prokaryotes like bacteria  cell division take place through binary fission, while eukaryotes (e.g., plant and animal cells) uses two types of cell division - mitosis (the process of making new body cells like blood, muscle etc ) and meiosis (reproductive cell division that creates egg and sperm cells).

Binary fission is a simple and rapid process in which a single parent cell divides to form two genetically identical daughter cells. The main function of binary fission is reproduction.

In mitosis, a cell is replicated into exact copies of itself and duplicates all of its contents including the chromosomes and splits to form two identical daughter cells. It is a complex process in which cells pass through different phases called cell cycle during cell division.

Meiosis is a type of cell division in which four haploid cells are produced from a diploid parent cell having two copies of each chromosome, where the number of chromosomes in the parent cell is reduced to half by undergoing DNA replication and nuclear division.

Both binary fission and mitosis are types of asexual reproduction in which the DNA is copied and the cytoplasm is divided (cytokinesis) to form two genetically identical daughter cells, which contain an exact copy of the parent cell's DNA.

The Panama Canal was completed in 1914, and its depth is about 50 feet. After 1914, snapping shrimp species from which habitats
Mashutka [201]

Answer:

Option C

Explanation:

Please see the attached image for the panama canal

Solution

Shrimps are the species that live in the bottommost areas of any water body i.e the bottom of the river or at the base of an ocean floor. Some of them are in habit of hiding themselves into the sand, mud, and rock along the sea shore.  

In the image, the region  A1 and B1 is the region closest to the ocean surface and as stated earlier some species of shrimps live close of sea/ocean surface. Thus, A1 and B1 regions will have shrimp hybrids.

 Hence, option C is correct
