The correct option is B.
Chromosomes can be classified as either homozygous or heterozygous based on the similarities between two alleles. A homozygous chromosome refers to a chromosome that have identical alleles on both homologous chromosomes. When the trait is dominant, it is represented by two capital letters; when the trait is recessive, it is represented by two lower case letters.
Urethra. <span>
<span>It is
a narrow tube that is connected to both the bladder and the ejaculatory duct
(in that order). It is therefore responsible for transporting urine and semen
from the body. It is a fibro-muscular duct that is housed by the penis. It
outer part of the urethra contains some sphincter muscles that allow
voluntary control over urine while the inner part of the urethra allows for
involuntary transmission of semen during ejaculation.</span></span>
<h2>Gelatin </h2>
Explanation:
Gelatin is a differential medium which tests the ability of an organism to produce an exoenzyme, called gelatinase (this enzyme hydrolyzes gelatin)
When gelatin is at a temperature below 32°C (or within a few degrees thereof), it is a semisolid material and at temperatures above 32°C, it is a viscous liquid
When gelatin is broken down, it can no longer solidify and if an organism can break down gelatin, the areas where the organism has grown will remain liquid even if the gelatin is refrigerated
No the conclusion by student is not right because the tube must be runny after incubation followed by refrigeration to be considered gelatinase positive
Answer:
If i am not mistaken, that would the the cell membrane, made out of lipids and different proteins.
Answer:
I believe it is the burning of fossil fuels.
Explanation:
The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis.
The cycle of carbon is carbon is moved through the atmosphere (carbon dioxide) to organisms. It is then moved from one organism to the next in complex molecules. Next, it is brought back to the atmosphere as carbon dioxide again.
Simple explanation is carbon passed through the atmosphere and back to animals and plants.
