Answer: As a body cell grows, the ratio of SURFACE AREA to volume INCREASES. Before it grows to large, a cell will divide into two DAUGHTER cells. So that each new cell receives its own genetic instructions, the cell REPLICATES or copies, all of its DNA.

Answer:

Same, 50N

Explanation:

According to Newton's third law, any force exerted on an object is exerted back with the same magnitude. The magnitude of the action force is the same as the magnitude of the reaction force. In the example, the chair would be pushing back with a magnitude of 50N.

I hope this answer helps.

<h2>Frequency-Dependent Selection</h2>

Explanation:

Frequency-dependent selection can be determined in a variety of ways, which are not different, yet all convey the feeling that the wellness of a phenotype or genotype changes with the phenotypic or genotypic structure of the population. Such determination can promptly keep up phenotypic variety and hereditary variety at a solitary locus. The support of polygenic variety with recurrence subordinate determination are to some degree more prohibitive than in the single locus case
Utilizing a recreation model, Mani et al. (1990) investigated the consolidated impact of change, balancing out ward choice, and recurrence subordinate determination on a hereditary framework in which there are n (≤12) loci, each with up to 32 alleles that demonstration additively, the i allele contributing an amount I to the genotypic variation
Hence, the right answer for the fill up the blanks is "Frequency-Dependent Selection"

Describe the general flow of energy through an ecosystem beginning with the Sun and going through a third order consumer.

Illusion [34]

Answer:

1) Autotrophs transform solar energy into chemical energy.

2) Herbivores and omnivores (primary consumers) eat producers, make use of some of the energy, making from it their biomass.

3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy.

4) Decomposers (last order in the chain) recycle all the dead organic material and make use of some of the stored energy.

Explanation:

<u>Energy flow: </u>From the whole quantity of energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.

From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.

Organisms that can use light, and turn it into organic matter according to their own needs are producers, and they are called autotrophic organisms. These organisms are by excellence all plants, algae, and bacteria that photosynthesize. Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy. In the trophic web, heterotrophic organisms occupy the first, second, or third consumer level, after producers. There are different types of heterotrophic animals: carnivorous, herbivorous, omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.

At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called <u>"The 10% rule".</u> This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

The progressive reduction of energy determines the number of trophic levels in the chain (4 or 5).

1) Autotrophs use water, CO2, and solar energy to produce O2 and glucose, by the process of photosynthesis and convert it into biomass. Producers transform solar energy into chemical energy.

2) Herbivores and omnivores (primary consumers) make use of some of this energy to survive, making from it their biomass. The rest of the energy is lost.

3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy. The rest of the energy is lost.

4) When different organisms die, decomposers (last order in the chain) recycle all the organic material and make use of some of the energy stored in their tissues. The rest is lost.
