Q3.13. In our simulation of herbivores feeding in a farm pasture, we treated each species as if it were foraging all by itself.

Of course, in real ecosystems, there are many different herbivores, some of which compete with one another for food. If both sheep and grasshoppers were feeding in a pasture, how do you think the grasshoppers would affect sheep

Answer:

<em>The grasshopper competes with the sheep for food, thereby reducing the available quantity and quality of food for the sheep.</em>

Explanation:

In an ecosystem, many organisms rely on the same food source. The success of a particular species in extracting the food source better than another species that needs that same food source can affect the success of  population of this other species of animal. If the number of grasshopper in this pasture becomes too much, it might lead to the consumption of a large portion of the pasture by the grasshopper, leading to a reduction in the available food for the sheep. If this happens, the population of the sheep might decline in order to balance the increase in the population of the grasshopper.

OPTIONS:

a. When there are just two other people at the party.

b. When everyone is wearing a nametag.

c. When there are more than 50 people attending the same party.

d. When the need for help from the person who is having a heart attack is very clear

Answer:

c. When there are more than 50 people attending the same party.

Explanation:

Bystander effect is a term used in social psychology to describe the tendency of an individual to intervene in the event of an emergency to offer help to the person needing it, when others are present at the scene of the emergency.

In the case of an emergency just like the scenario stated in the question, where someone develops a heart attack at a dance party, if the party has more people, the slimmer the chance of the person getting help from any of the 50 people at the party, as the presence of others would tend to discourage the any individual from attempting to help the victim having the heart attack.

The situation that would more likely show the bystander intervention effect is <em>"c. When there are more than 50 people attending the same party."</em>

How to zoos affect the nitrogen cycle
SpyIntel [72]
<span>As humans change the way we live on the planet, the way that nitrogen moves around the Earth also changes. Nitrogen atoms may seem small enough to be easily overlooked. We look right through the ones in the air, do we not? Yet recent changes in the nitrogen cycle are causing a very noticeable effect on natural environments and human health. Lakes are clogged with aquatic weeds. Dead zones have formed in areas of the oceans where animals can not survive. Air pollutants that contain nitrogen are decreasing air quality and greenhouse gases that contain nitrogen are becoming more common.</span>

In humans, methylation of chromosomal DNA is a signal that often leads to
Ulleksa [173]

Answer:

The correct answer will be option-formation of heterochromatin

Explanation:

Methylation of DNA is the epigenetic mechanism which controls the expression of a gene by adding a methyl group to the cytosine bases in eukaryotic DNA.

The methylation of DNA converts the cytosine residues to the  5-methylcytosine catalysed by DNA methyltransferase enzyme. This results in the silencing of the gene and transcription get switched off.

Studies have shown that DNA methylation is involved in the formation and maintenance of the heterochromatin structure which is the condensed form of the chromatin in which transcription is switched off.

Thus, the formation of heterochromatin is the correct answer.
