Answer:

Option A.

Explanation:

Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose.

Homologous structures are organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor. These structures do not have to look exactly the same, or have the same function

Vestigial structures no longer carry out any function.

Select the correct answer from each drop-down menu. If a heterozygous male with the genotype Ww is mated with a homozygous reces
g100num [7]

If a heterozygous male with the genotype Ww is mated with a homozygous recessive female with the genotype ww, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are Ww, Ww, ww, and ww.

<h3>What is Genotype?</h3>

A genotype may be defined as the ultimate combination of the alleles of those genes which are selected for specific studies.

If a heterozygous male with the genotype Ww is mated with a  homozygous dominant female with the genotype WW, then the probability of heterozygous offspring is 0.5 or 50%. The offspring are WW, WW, Ww, and Ww.

Therefore, it is well described above.

How is the law of conservation of mass applied to ecology?
Thepotemich [5.8K]

In ecology, the law of conservation of mass is applied by the principle of taking energy from the lower trophic levels and passing it to the higher trophic level by any means.

<h3>What is the law of conservation of mass?</h3>

The law of conservation of mass states that the actual mass in an ecosystem is neither created nor destroyed. Overall remains constant in a system.

In ecology, it illustrates that when an organism is ingested by other organisms, its mass is conserved. Some of the organisms may also be dependent on the waste products like urine and feces to make proteins and other compounds.  

Therefore, the energy or mass is neither lost in any form. It simply is taken by other organisms through any means.

Marina86 [1]

The correct option is D: the living part of the cell, including the cell membrane.

The protoplast consists of the living part of the cell, including the cell membrane.

protoplasts are round-shaped cells that are produced by a digestive enzyme. a cell without a cell wall is called a protoplast.

It can be produced by removing the cell wall from a plant or fungi cell through mechanical, chemical, and enzymatic means.

They provide a buffered environment and mechanical support to plants along with the transportation of minerals and water.

Ozone in the troposphere is necessary to protect Earth's surface from harmful UV radiation.
romanna [79]

Answer:

False

Explanation:

In the troposphere, near the Earth's surface, human activities lead to ozone concentrations several times higher than the natural background level. Too much of this ground-level ozone is 'bad' as it is harmful to breathe and also damages vegetation.

The stratosphere or “good” ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the sun's harmful ultraviolet (UV) rays.
