Answer:
12
12
24
Explanation:
<em><u>Musca</u></em> <u><em>domestica</em></u> is the scientific name of an animal popularly known as Housefly. From the question, it is known that this organism has a haploid chromosome number of 6.
In a diploid chromosomes, the number of chromatids that will be present will be twice of that in haploid.
Since haploid (n) = 6, diploid (2n) will be; 2 × 6 = 12
Somatic cells on the other hand also exhibit diploid number of chromosomes, again it means we will have (2n) = 2 × 6 = 12
In metaphase cell, cells do make sure they complete the S'phase of the cell cycle before cellular division.Therefore, the DNA present in the chromatids in the S'phase actively engage in chromatids doubling, as a result, 24 chromatids (i.e 12 × 2= 24) exists in the metaphase cell.
Ecosystem services are the flows of benefits which people gain from natural ecosystems
Natural Resources are materials or substances that occur in nature and can be used for economic gain.
Answer:
Because the vaccine is an antigen from living, weakened or killed microorganisms that activate the immune system and the body produces protective antibodies.
Answer:
Ethel is correct because energy is not carried from one place to another.
It is a transverse wave.
Explanation:
During the propagation of waves from one point or place to another, energy is being transferred. Thus, when one's hand is being waved, there is no transfer of energy from one point to another. Therefore, Ethel is right while Brody is wrong.
A transverse wave is known as a type of wave that the direction of propagation is perpendicular to the vibration of the medium. Therefore, the wave is a transverse wave.
Most scientists directly involved in animal behavior are found within two disciplines: Ethology and comparative psychology.<span>
