If female deer mates with male deer that have large antlers 2 we are witnessing_____ selection.

1 answer:

3 0

The answer would be natural selection.

The female deer might consider the large antlers of the male deer to show of certain genetic qualities that have a higher probability of reproduction, as well as a higher social status among deers.

This means that if she picks him as her mate during this season, their offspring will have a better chance of survival compared to her picking another deer with smaller antlers.

This is called natural selection because she will pick the deer that is most adapted to that environment. Thus their offspring can be ensured to have the highest possible probability to survive.

How are energy inputs and outputs related to chemical reactions

GREYUIT [131]

The large number of areas covered by the chemical energetics can be explained by the different forms in which chemical energy can be released: heat and combustion work, electrical energy in electrochemistry, radiant energy in chemiluminescent systems.

The chemical energy provided by a reaction reflects the energy balance associated with the electronic modifications suffered by the species involved.

From an energy point of view, a chemical reaction between molecules can be schematized in two stages. The first requires a supply of energy and corresponds to the rupture of the bonds of the reactant molecules with release of the atoms which constitute them.

The second releases energy and concerns the creation, by recombination of these atoms, of new bonds entering the structure of the reaction molecules.

As a general rule, the energy released in the second stage is greater than the first. We are talking about exothermic reaction. The difference between these two energies (reaction enthalpy) measures the amount of chemical energy transferred to the external environment.

It is conceivable that this quantity translates, not only the number, but also the strength of the connections involved.

Worms move using an hydrostatic skeleton. How do worms move?

Nadusha1986 [10]

Answer:

The correct answer is B. Worms move through changes in body structure caused by contraction of muscles compressing their watery fluid.

Explanation:

The hydroskeleton consists of a fluid-filled cavity, surrounded by muscles. The fluid pressure and the action of the muscles that border it, serve to change the body's shape and produce a movement such as digging or swimming. The successive contraction of various metamers, which are provided with bundles of circular and longitudinal muscle fibers, stretching and thickening parts of the body, allow it to move horizontally. Hydrostatic skeletons have a role in the locomotion of annelids, nematodes and other invertebrates. The hydroskeleton has similarities with the hydrostatic muscles.

Drag the terms on the left to the appropriate blanks on the right to complete the sentences. resethelp biomass assimilated feces

yaroslaw [1]

1. The right answer is not assimilated

The assimilation designates in biology the process by which substances and materials external to the body are transformed into substances and materials interior to the body.

2. The right answer is feces.

Feces correspond to the residue of digestion that the intestine could not absorb. They consist of 80% water and 20% dry matter (intestinal cell debris, bacteria, cellulose that comes from the non-absorbable part of plants).

3. The right answer is assimilated

The opposite of the first one.

4. The right answer is cellular respiration.

Cellular respiration is the process of cellular metabolism that converts the chemical energy contained in nutrients into ATP (adenosine triphosphate).

5. The right answer is assimilated

"Assimilation" can be also used for energy.

6. The right answer is biomass

In the field of energy, biomass is the organic matter of plant origin (microalgae included), animal, bacterial or fungal (fungi), usable as a source of energy.

7. The right answer is biosynthesis.

Biosynthesis consists of a formation and production of a chemical compound body by a living organism, usually due to the catalysis of an enzyme. For example, protein synthesis is the synthesis of organic substances by an organism. Chemosynthesis and photosynthesis are biosynthesis.

8. The right answer is non assimilated.

Since it is lost, so it is not assimilated by the organism.

9. The right answer is biosynthesis.

In ecology, the trophic level is the rank occupied by a living being in a food web. It is measured in some way by the distance separating this being from the basic level which is that of the primary autotrophic production.

Above this basic level, each link (or stage) of a food chain corresponds to a trophic level.

Why has ground water use increased

Contact [7]

Answer:

The principal reason for the increase of groundwater use is the increasing population. Urbanization and pollution have both contributed to an increase in the use of groundwater. Polluted rivers, lakes, and springs are no longer viable sources of groundwater.
