Some practices that can be done to stop pollution of fresh water and overuse of freshwater are:-
- Properly dispose of hazardous productsPut up signs.
- Use and dispose of harmful materials properly.
- Volunteer in your community.
- Join in a beach, stream or wetland cleanup.
- Prepare a presentation about your watershed for a school or civic organization.
- Organize a storm drain stenciling project.
Answer:
Not sure but for billions of years. I don't think anyone can tell you an exact answer because it wouldn't make sense.
Explanation:
if someone else answers please give me brainliest it would be appreciated! <3
Answer: Point source
Explanation:
An exotoxin is a toxic substance secreted by bacteria. The botulism exotoxin is the exotoxin secretes by bacterial strain named as Clostridium botulinum.
Point source outbreak is a condition in which people are exposed to the same source of infection from a pathogen. This may occur due to the consumption of a single meal which is being infected by the pathogen. This may lead to incidences of food poisoning, disease and even mass death.
Answer:
a. There are different possible ways that homologous pairs might line up
c. Different alignments of homologous pairs will cause different combinations of alleles in gametes.
Explanation:
The law of independent assortment, proposed by Mendel, states that the alleles of one gene segregate into gametes independently of the alleles of another gene. This means that the segregation of one gene does not affect another. This law of independent assortment is evident during gamete formation in sexually-reproducing organisms know as meiosis. Specifically, in the Metaphase 1 stage of meiosis 1, homologous chromosomes (similar but non-identical chromosomes received from each parent) lines up at the metaphase plate (cell equator).
The lining up of chromosomes in this stage occurs randomly making it possible for chromosomes to align in different possible ways. The way/manner the chromosomes align at the equator determines which chromosome combination gets separated into which gamete. The homologous chromosomes are randomly distributed at the cell's equator before segregates into gametes. This random orientation enables the alleles of each gene on a chromosome to combine in different random ways, hence, allowing genetic diversity in the resulting gametes (sperm and egg) they get segregated into.
A protein's shape directly affects how well it works. For instance, a protein works as a protective protein or a structural protein if its structure is fibrous, as is the case with proteins like collagen and keratin. The protein becomes denatured and ceases to serve its intended purpose if the structure of the amino acids is altered in any way.
<h3>What are amino acids?</h3>
Organic substances known as amino acids have both functional groups for amino and carboxylic acids. Alpha-amino acids, which make up proteins, are by far the most significant amino acids in nature, despite the fact that there are hundreds of other types. The genetic coding only contains 22 alpha amino acids. An organic compound is an amino acid. Carbon-hydrogen bonds are present in organic compounds. All amino acids share a similar fundamental structure. Each molecule has a core carbon atom that is joined to a hydrogen atom, a basic amino group, a carboxylic acid group, and an R-group, also known as a side-chain group.
