To determine the genotype of this plant, a test cross should be performed. The expected phenotypes of the descendants are yellow and green peas.

An F1 progeny is bred with a double (homozygous) recessive(green pea) mother generation to determine if an offspring is homozygous or heterozygous for a specific characteristic. A test cross is what this is called.

If the hybrid's mother is homozygous (YY) dominant, all of the hybrid's offspring will have the dominant (yellow) phenotype.

Mother yellow pea (YY)     x       green pea (yy)                 - P generation

                                  Y                            y                           - Gamete

                                   Yy (yellow) , Yy (yellow)                   -F1 generation

The ratio should be 1:1 if the mother is heterozygous dominant (Yy), in which case half of the kids will display the dominant phenotype, while the other half will display the recessive phenotype(yy).

Mother yellow pea (Yy)     x         green pea (yy)              -P generation

                                 Y, y                             y                       - Gamete

                                 Yy (yellow) , yy (green)                       -F1 generation

The conclusion drawn from the foregoing explanation is that in order to determine the genotype of the pea plant, a test cross should be conducted. The expected progenies are - yellow and green peas.

The presence of a large population of water lice in a water source indicates that organic pollution is moderate but declining. Oxygen levels are just beginning to increase (option A).

What are indicator species?

Indicator species are living organisms that tells us about the pollution status of our environment (water, air, land) by being absent or present.

Examples of indicator species are as follows;

Water louse

Lichen

According to this question, there is an abundance of large population of water lice in a water body.

This could indicate that organic pollution is moderate but declining and oxygen levels are just beginning to increase because water lice are known to thrive in water bodies with moderate pollution.

Answer: Summer

Explanation: When the southern hemisphere is closest to the sun, and it receives the most sunlight it is summer time, while in the northern hemisphere it's winter.

The main factor that determines seasons is the way sun rays enter Earth, and not as much proximity, since there is only a 2% variation in the distance overall

The structure that caused rotifers to be called wheel animals or wheel bearers is the corona.

Rotifers are also known as wheel animals or wheel bearers because of the corona structure around their mouth region.

Some rotifers are sessile and live inside tubes or gelatinous holdfasts that are attached to a substrate. Other rotifers migrate around a substrate through inch worming.

This is because when corona is seen in a sequential coordinated movement, it resembles the structure of a wheel, although it does not rotate in reality.

Therefore, we conclude that rotifers are called wheel animals or wheel bearers due to the presence of the corona structure.

A proton gradient is an important part of both photosynthesis and cellular respiration because couple the favorable flow of H+ to transport specific metabolites into and out of organelles.

The gradient is sometimes called the proton-motive and can be thought of as a form of energy, force and force in a battery. Like other ions, protons are not able to cross directly through the phospholipid bilayer of the membrane, as the interior of the membrane is hydrophobic.

The proton gradient generated by this manipulation provided a driving force for ATP synthesis in the absence of light. This confirms the chemiosmotic theory, where a chemical potential across the membrane can provide energy for ATP synthesis.

The proton gradient produced by pumping protons during the electron transport chain is used to synthesize ATP.

The niche available after extinction can lead to speciation because there would be an imbalance, making resources formerly occupied by extinct fishes vacant, providing the emergence of new species to take the place of the extinct species.

Speciation can be understood as processes that lead to the formation of new species. They occur due to differences in the genome of different populations of the same species that caused reproductive isolation and, consequently, the appearance of two different species.

With this information, we can conclude that Speciation is the process of formation of new species from lineage separation events from preexisting species.
