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.

Which of the following results when a person’s hand is near an open flame?
Ede4ka [16]

Given what we know, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.

<h3>What happens when a person's hand is near a flame?</h3>

We can say that the information from the heat being generated by the flame is received by sensory neurons in the person's hand. This information generates a pain response which is integrated as incoming information in the brain, which then produces a motor response to move the hand away from the flame, as an outgoing signal.

Therefore, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.

Ne4ueva [31]

Answer:

The answer is "Option e".

Explanation:

please find the complete question in the attached file.

Its long tail disregards its short tail. Let's assume that even a short neck is a as well as a tail over, which claim, though, the short tails were mixed, shorter, and longer tailed mousses are created. It may also presume that the short mouse parental is always Aa. And we get AA, Aa, Aa, Aa, and Aa situations once their matter and they fall pregnant to both high and short tail mice but we wouldn't get the fat tail mouse unless the tail-mouse were as AA.

we always get two types of lines. It demonstrates there was no uniform AA genera. It is a case of the heterozygous dangerous gene, that can cause a set of identical alleles inside an organism to always be lethal.

Keith_Richards [23]

Answer:

37

Explanation:

Since the Gruffalo has a somatic chromosome number of 67 and the Buffalo has a somatic chromosome number of 60, we may infer that seven chromosomes from the Grizzly were not able to pair up with the chromosomes of the Buffalo. Checking the options, the only choice that has a suitable number is b. 37 chromosomes. If this is true, then the remaining 30 chromosomes were able to pair up.

In the antarctic region, biologists noticed a sudden drop in the death rate of penguins. How will this affect their population?
frez [133]
So, a sudden drop in the death rate means that while everything stays the same, less penguins are dying: the penguins are living longer! This means that the population will increase: there will be more penguins at all times!
