The following Punnett Square is a monohybrid cross. It takes the genotypes of the parents and predicts the genotypes of their of
Aleonysh [2.5K]

Answer:

For the 1st block on the left I think there are 2 dominants for that would be BB. The 1st block on the right would be 1 dominant and 1 recessive and that would be Bb. The bottom on the left would be the same as the first block on the right. That would be Bb. The last block that would be the bottom right would be 2 recessives and that would be bb. I hope this might help.

Explanation:

When you are doing punnet squares, you have dominant and recessive traits. There are ways you can do that. If you have 2 alleles of each parent of that offspring, there will be a genotype and a phenotype that represents a genetic trait of each genotype. I hope this helps your question.

Once amylase has broken down starch, can it break down another starch molecule?
Juliette [100K]

Answer:

Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.

Explanation:

Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.

The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.

Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.

How does overtillage harm soil?
jeyben [28]

Answer:

A. Overtillage can increase the rate of humus decomposition

Explanation:

We refer to humus as any material of an organic nature that undergoes soil degradation. Humus is very important for agriculture because it has high nutrient levels that it provides to all crops. This causes more crop productivity, increases the producer's profit and increases the number of food available to the population.

Humus is a difficult to decompose material, but under favorable conditions it can decompose quite easily. Due to the presence of large amount of burnt organic matter in the soil, it is sometimes difficult to increase the humus content, so the exhaustion of this organic matter is caused by over tillage, especially in regions of tropical and sub-tropical climate, poorly managed. farmer protection and unprotected effects of erosion.
