Answer:

Mitochondria stops working.

Explanation:

When the mitochondria of fish exposed to Rotenone, it inhibits the cellular respiration which is the main cause of death of fishes. This inhibiting of cellular respiration in mitochondria leads to reduction in cellular uptake of oxygen and this reduction is responsible for the death of fishes. This Rotenone releases by the plants present in the water as well as used as pesticides for killing of fishes.

ira [324]

Answer:

ATP, is a molecule  called adenosine triphosphate.

This molecule takes part in coupled reactions:This molecule participates in a large number of biochemical reactions, this molecule is the energy contribution of reactions, it appears in the Krebs and glycolysis cycle.

This molecule is a type of nucleotide.

ATP is a nucleotide formed by three phosphate groups and an adenosine. The nucleotide is adenine with three energy-rich phosphate groups.

*The key function of each of the two photosystems is to absorb light and convert the energy of the absorbed light into redox energy, which drives electron transport.

In PS II (the first photosystem in the sequence), P680 is oxidized (which in turn oxidizes water), and the PS II primary electron acceptor is reduced (which in turn reduces the electron transport chain between the photosystems).

In PS I, the PS I primary electron acceptor is reduced (which in turn reduces other compounds that ultimately reduce NADP+ to NADPH), and P700 is oxidized (which in turn oxidizes the electron transport chain between the photosystems).

. Pepper colors range from bright red, orange, and yellow shades, to dark green and brown shades. Coloration in bell peppers is
sattari [20]

Answer:

All crosses and proportions, genotypes and phenotypes are attached.

Explanation:

a. Within living organisms, staining is a characteristic governed by a polygenic inheritance, which means that there is more than one gene involved in the staining process. as you already know, each gene has two alleles, if a trait is controlled by 2 genes, it means that we will have 4 alleles at the crosses.

From the description between dominance and recessivity between the alleles that control the colors of the pepper, shown in the question above, we can see that for the crossing between a red pepper and a green pepper, being able to generate a completely orange offspring, it would be necessary that the genotype of the parent peppers was: Red: RGRG, green: rgrg.

This would generate an orange-colored RrGg offspring, as you can see at the F1 crossing.

b. When individuals of F1 offspring are crossed, the combination of alleles and the determination of genotypes and phenotypes becomes much more complex, because instead of 4 alleles, we will have the combination of 16 alleles among themselves. Once again we will need to rely on the description of dominance and recessivity shown in the question above, so that from the crossing between the alleles of each gene, we can reach a conclusion, as you can see in the F2 crossing.

Find the sum of a 9-term geometric sequence when the first term is 4 and the last term is 1,024 and select the correct answer be
atroni [7]
First, we need to solve for the common ratio from the data given by using the equation.

a(n) = a(1) r^(n-1)
1024 = 4 r^(9-1)
256 = r^8
r = 256^(1/8)
r = 2

Then, we can find the sum by the expression:

S(n) = a(1) ( 1 - r^n) / 1-r
S(9) = 4 (1 - 2^9) / 1-2
S(9) = 2044

Therefore, the correct answer from the choices listed above is option B.
