Answer:
fertilizer creating a mutation among a farmer's crops
Explanation:
A genetic factor is one that affects the gene or genome of an individual organism. This genetic factor often influences the observable trait called PHENOTYPE of the organism. In this case, an example of a genetic factor that could influence the growth or development of an organism created by an environmental factor is the "fertilizer creating a mutation among a farmer's crops"
The fertilizer represents the environmental/chemical factor which is creating the genetic factor (mutation) that will eventually influence the growth or development of the crops.
Answer:
Before the advent of modern biology, study of life and organism was in the realm of natural philosophy and was never in the club of classical sciences like physics, chemistry and engineering. Today biology is a science that studies life and living organisms.
Explanation:
A biologist can be categorized as a scientist because all the processes that supports scientific investigations are carried out in the study of biology- data collections, critical thinking, observation and collection of result for the purpose of public consumption.
On the other hand forensics is the mainly the aplication of science-mostly biology- in resolving criminal activities. It involves the collection of samples, anaylsing and presentaion of result for decison making.
Explanation:
The problem says that the hairless phenotype never breeds true. That means that it's not the result of a homozygous genotype (H₁H₁ or H₂H₂), so it is caused by the heterozygous genotype (H₁H₂).
The <u>expected </u>offspring from the cross between two Mexican hairless would be:
<h3>P
H₁H₂ x
H₁H₂</h3><h3>F1 1/4
H₁H₁, 2/4
H₁H₂ and 1/4
H₂H₂.</h3>
And the <u>expected</u> phenotypic ratio 3:1. However, the observed offspring shows a 2:1 ratio. What's happening?
If the observed phenotypic ratio in the offspring of a monohybrid cross (a single gene with two alleles) is 2:1, we can suspect that one of the genotypes is lethal in homozygosis and therefore does not appear in the progeny (the puppies are born dead).
If we proposed that the H₂ allele is lethal in homozygosis, then:
- The H₁H₁ genotype would cause normal puppies --> 1
- The H₁H₂ genotype would cause hairless puppies --> 2
- The H₂H₂ is lethal and causes the death of puppies --> 0
The phenotypic ratios change to 2:1, as observed in the experiment.
It happens in glycolysis. It gets broken down into two pyruvates and it happens in the cytoplasm.
The significant role of spore formation in the reproductive cycle of this bacterium would be to allow the bacteria to survive in extreme conditions. The spore formed is called an endospore which is a thick cover made of protein. These spores are mostly resistant to heat and chemicals which makes the bacteria survive in harsh conditions. Spores can only be destroyed by sterilization and it require very high pressures and very temperatures. In microbiology and medical settings, this process is usually done in a device known as the autoclave. Sterilization is a process that involves the killing of all microorganism in a system whether it is harmful or beneficial.
