How does artificial salmon breeding affect the native Populations? What challenges do ecologists and conservationists face in the salmon industry ?
Answer:
When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.

3. For each phenotype below, list the genotypes (remember to use the letter of the dominant trait)
Straight hair is dominant to curly Tail spikes are dominant to plain tails
straight
spikes
straight
spikes
curly
plain
Answer:
See the answer below
Explanation:
Let the allele for hair color be A (a) and the allele for tail shape be B (b). Straight hair A is dominant over curly hair a and spikes B is dominant over plain tails b. Hence, the phenotypes and their respective genotypes would be as follows:
Phenotype Genotypes
Straight hair AA or AaSpikes BB or BbCurly aaPlain bbHow does meiosis play a role in the evolution of a species
A. It increases the reproduction rate of the species
B.it increases the amount of genetic variation in the species
C. It reduces the amount of competition between members of the species
D. It increases the ability of individuals in the species to obtain resources
Answer:
The correct answer is - option B. it increases the amount of genetic variation in the species.
Explanation:
Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.
The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.
Scientists have noticed that the entire DNA molecule has the same width, despite the fact that the four nucleotides are NOT the same width Now that you’ve created a model, explain why this makes sense (hint: it has to do with the number of rings for each nitrogen base)
I don't have access to your model, although I'm sure it's beautiful. Fortunately, this question can be answered without one.
A strand of DNA is a polymer consisting of monomeric nucleotide units. The nucleotides that are found in DNA are distinguished by their nucleobases: adenine (A), thymine (T), guanine (G), and cytosine (C). Each nucleotide in DNA is made up of a single nucleobase, a sugar (deoxyribose), and a phosphate group. These nucleotides form extremely long chains comprising phosphate-sugar linkages (covalent, phosphodiester bonds).
In native, double-stranded DNA, you have of these chains (or strands) arranged side-by-side such that the nucleobases on one chain are faced directly across corresponding nucleobases on the other chain, which enables hydrogen bonding between the bases.
There is a "rule" regarding which bases form hydrogen bonds with one another (Chargaff's rule): adenine with thymine and guanine with cytosine.
What does this have to do with the width of the DNA molecule?
The four nucleotides can be structurally classified into two categories: pyrimidines and purines. For our purposes, we only need to know that pyrimidines are six-membered rings and purines are a fusion of a six- and five-membered ring (basically, purines are pyrimidines attached to a five-membered ring). Thymine and cytosine are pyrimidines, and adenine and guanine are purines.
So, geometrically, adenine and guanine are larger (and, thus, "wider") than thymine and cytosine since adenine and guanine contain an extra ring. But remember our base-pairing rules: In native DNA, adenine (two rings) on one strand pairs up with thymine (one ring) on the other strand, and guanine (two rings) pairs up with cytosine (one ring) on the other strand.
Because there's a 1:1 ratio between A:T and G:C in double-stranded DNA, the DNA molecule consists of complementary base pairs that, in any given composition of, has equivalent widths. Put simply, the A=T pair has the same width as a G≡C pair because both base pairs are between one pyrimidine and one purine.
DNA (Deoxyribonucleic acid) is composed of four nucleotides, namely, adenine, guanine, cytosine, and thymine.
Adenine and guanine are purines while Cytosine and thymine are pyrimidines.Purines are composed of two rings while pyrimidines are composed of only one ring.Purine forms bond with pyrimidine, i.e Adenine binds with thymine and guanine binds with cytosine.Adenine and thymine form two hydrogen bonds while guanine and cytosine form three hydrogen bonds.Thus, the relative pairing of the purine and pyrimidine with each other keeps the width of the DNA constant.

What 2 chemicals are inside skeletal muscle?
Answer:
Skeletal muscle tissue is composed of cells called muscle fibers. When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber.
The 2 chemicals inside skeletal muscle are : i) Organophosphate ( OP ) and ii) Acetylcholine ( ACh )
The skeletal muscle is toxic in nature due to the presence of certain chemicals ( Organophosphate and Acetylcholine ). and this causes the skeletal muscle to experience some level of toxicity. some of the toxic effects caused by the presence of these chemicals in the skeletal muscle include :
weakness of the muscle.partial/complete paralysis.muscle hyperactivity.Hence we can conclude that the 2 chemicals that can be found inside skeletal muscle are Organophosphate ( OP ) and Acetylcholine ( ACh )
