Which abiotic factor most likely controls where the plants live in this environment
Setler [38]

Which abiotic factor most likely controls where the plants live in this environment ?

Oxygen levels for aquatic animals

Oxygen from the air and oxygen produced by aquatic plants dissolves in water. Without this, aquatic animals would suffocate and die. Healthy lakes and rivers have high levels of oxygen, and polluted waters often have low levels of oxygen. This pollution means that only certain species can survive there such as sludgeworms. These are bioindicator species because their presence or absence informs us about the condition of the habitat.

Carbon dioxide levels for plants

Carbon dioxide is a reactant in photosynthesis which means plants need it to survive. Areas with higher levels of carbon dioxide are more likely to have healthy plants growing. Farmers often release carbon dioxide within their greenhouses to maximise their crop yield. Woodlands often have higher carbon dioxide levels than open grassland, so many plants living in open areas have evolved mechanisms to overcome a shortage of carbon dioxide.

Barred feather pattern is a Z-linked dominant trait in chickens. What offspring would you expect from (a) the cross of a barred
Bezzdna [24]

Answer:

Let the "barred" allele be caller B and the "non-white" allele b. Since chickens use chromosomes Z  and W to determine sex, hens would have chromosomes ZW, and roosters would have chromosomes ZZ. A Z-linked gene is represented as a superscript on the Z chromosome, Z^{B} for the dominant allele and Z^{b} for the ressesive allele.

A barred hen would have a copy of B on its Z chromosome, a non-barred rooster would have both copies of b on both Z chromosomes. Using Punnet squares to represent the crosses we get the following cases:

\begin{center}\begin{tabular}{ |c|c|c|c| }\ & Z^{B} & W \\ \ Z^{b} & Z^{B}Z^{b} & Z^{b}W \\ \ Z^{b} & Z^{B}Z^{b} & Z^{b}W \\ \end{tabular}\end{center}

That is a ratio of two barred heterozygote roosters to two non-barred hens. Crossing them we get:

\begin{center}\begin{tabular}{ |c|c|c|c| }\ & Z^{b} & W \\ \ Z^{B} & Z^{B}Z^{b} & Z^{B}W \\ \ Z^{b} & Z^{b}Z^{b} & Z^{b}W \\ \end{tabular}\end{center}

That is a ratio of one barred heterozygote rooster to one barred hen to one non-barred rooster to one non barred hen.
