Biology

1 answer:

Lesechka [4]3 years ago

Answer:

Oxygen or Minerals or Sugars (Oxygen is the most relevant one)

Explanation:

To survive, every cell must have a constant supply of vital substances such as sugar, minerals, and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.

Why can viruses not fit in any domain? How are they different from all other forms of Life? What would need to occur for viruses

Wittaler [7]

Answer:

virus are obligate parasites. Viruses do not, however, carry out metabolic processes. Most notably, viruses differ from living organisms in that they cannot generate ATP.

How might volcanic eruptions change the flow of energy on earth?

Maksim231197 [3]

Answer:

It causes global warming due to emission of carbondioxide gas.

Explanation:

Volcanic eruptions change the flow of energy on earth by emitting gases such as carbondioxide and sulfur dioxide gases. Volcanic gases like sulfur dioxide is responsible for global cooling by reflecting solar radiation back to the space, while on the other hand, carbon dioxide emitted from volcanoes, has the ability to promote global warming by blocking solar radiation. If the amount of carbondioxide gas is higher as compared to sulfur dioxide gas so global warming occurs.

In the process of carbon fixation, three molecules of RuBP combine with three molecules of CO2 to produce three six-carbon molec

Olin [163]

Answer:

what is needed to be done is reduction of the 12 glyceraldehyde 3-phosphate, in presence of NADPH, and hydrolysis of ATP to produce 2 molecules of triose phosphate.(TP). The point of carbohydrate production in photosynthesis.

Statistically 5/6 of the TP is used to regenerate RuBP,for the cycle to continue, while the remaining 1/6 is for production of other molecules; glucose, Amino acids and lipids.

This marks the end of Calvin Cycle.

PLZ HELP ME ANSWER THESE QUESTIONS

rosijanka [135]

Answer:

In document

Explanation:

Part 1

The freckles allele (F) is dominant to the no freckles allele (f). The parents are both heterozygotes, Ff, and both freckled. When they are crossed (Ff x Ff) in the resulting offspring:

There is 1 FF genotype, 2 Ff genotypes, and 1 ff genotype. FF and Ff give freckles, because F is dominant to F.

ff gives no freckles.

Therefore:

Genotypes: 1 FF: 2 Ff: 1 ff

Phenotypes: 3 freckles: 1 non-freckles

Part 2

Both parents are heterozygous at both traits, so their phenotypes are both PpRr.

Due to the law of independent assortment, the alleles in each trait are sorted into gametes independently. That means the gametes can have any combination of flower and seed alleles. The possible gametes in both parents are:

Gamete 1: PR

Gamete 2: Pr

Gamete 3: pR

Gamete 4: pr

When they are crossed (PpRr x PpRr - punnett square shown). The possible genotypes for each phenotype are:

purple flowers, round seeds: PPRr, PpRr, PPRr, PPRR, PpRR, PpRr, PpRr, PpRR, PpRr

purple flowers, wrinkled seeds: PPrr, Pprr, Pprr

white flowers, round seeds: ppRR, ppRr, ppRr

white flowers, wrinkled seeds: pprr

and the numbers of each phenotype are:

purple flowers, round seeds: 9

purple flowers, wrinkled seeds: 3

white flowers, round seeds: 3

white flowers, wrinkled seeds: 1

The classic ratio for a dihybrid cross between two heterozygote parents.
