g One can measure ATP production from isolated mitochondria in vitro (in a test tube). Changing the pH of the solution that the
Damm [24]

Answer:

This will lead to an  decreases  in the ATPs synthesis. This is because low pH , high acidity favours ATP synthesis, because it increases the  proton concentration for electrochemical gradients needed for energy that  ATPase enzymes makes used of   synthesis  of ATPs.

Therefore a rise in the pH(low acidity) lowers protons levels, and therefore reduced electrochemical gradients , with a drop in energy for ATPs synthesis.

Crawfish are shelled organisms that live in shallow freshwater rivers. They can have antennae of different lengths. Two parents
vredina [299]

The phenotype of antenna in crawfish depends on the protein amount in the antenna length. The offspring have different phenotype than their parent because of the amount of protein translated from each parent gene is determining in this.

The gene determines the amount of protein to be present in the antenna to determine its length.

Explanation:

Data given:

Two crawfish parent = medium length antennae, genotyoe Ll

One offspring = short antenna, genotype ll

one offspring = long antennae, genotype LL

The traits in offspring is shown as:

       L    l

L   LL    Ll

l   Ll     ll

The proportion of allele present in the gene determined the length of the antenna in crawfish.

The difference in length of the antenna in crawfish is due to the amount of protein for the phenotype present in the individual. The amount of protein to be expressed in the crawfish is given by both the parents. The tendency of protein expresed define the phenotype of antenna length.

Explain how phosphorus runoff into oceans and lakes from farming has a negative impact on the ecosystem.

It causes eutrophication which means that the algae have too much nutrients and take over the pond, use the oxygen so there is not enough left for marine life, which die as a result.
