You have a pea plant with a yellow pea phenotype but do not know if the genotype is homozygous (YY) or heterozygous (Yy). What type of cross would you do determine the genotype of this plant and what would be the predicted phenotypes of the offspring?

Answers

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

What does test-cross mean?

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.

Answers

Burning fossil fuels has increased pollutants and carbon dioxide in the atmosphere.

What consequences do fossil fuel burning have on the environment?

Carbon dioxide, water, and energy are produced when fossil fuels are burned; this process is referred to as "combustion".

Burning fossil fuels like coal and oil has increased the amount of carbon dioxide in the atmosphere during the past century (CO2). This rise is brought on by the burning of coal or oil, which produces CO2 when airborne carbon and oxygen mix. When fossil fuels are burned, nitrogen oxides are released into the atmosphere and help to create smog and acid rain. Nitrogen oxides are the collective name for the most prevalent nitrogen-related substances released into the atmosphere as a result of human activity.

2. What structure caused rotifers to be called wheel animals or wheel bearers?
1 the foot
2 the corona
3 the brain
4 the stomach

Answers

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.

What is the proton gradient?

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 cichlid is a colorful fish found in freshwater lakes. There are over a thousand species of cichlid fish today. If a species of cichlid became extinct, the niche the fish filled within the ecosystem would be left open. Explain how an available niche after extinction can lead to speciation.

Answers

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.

When does speciation occur?

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.
