Review the chart, which shows the population sizes of three African animals in 1990 and in 2000.

1 answer:

4 0

The explanation which is best supported by the numbers in the chart is that Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs. Thus, the correct option is A.

<h3>What is Competition in the population?</h3>

Competition in population may be defined as the existence of two or more same or different species that are actively fighting over the same resources and factors that they disseminate.

Competition and predation are the two types of species interaction through which the population of species either increases or decreases.

According to the given chart, it is noticeable that the population drop in predator cheetah and lion populations because of the reduction in zebra lowering population but the in cheetah population is additionally than that of the lion.

Therefore, the correct option for this question is A.

Imagine that four genes on a single chromosome in a mutant phenotype of Drosophila cross over at half the normal rate as in the

lesantik [10]

We know that frequency of recombination is proportional with the distance between the genes on the chromosome. Therefore when the recombination rate is higher that means the distance between the genes on the chromosome is bigger. If the recombination rate is lower that means the genes are closer to each other on the chromosome. In this case the cross over rate is half the normal rate in the wild-type. That means that on the genetic map the distance between the two genes on the wild type will be twice bigger than the genes of the mutated Drosophila.

deff fn [24]

C. To track the direction the outdoor sunflower heads were facing throughout the day.

Explanation:

The main aim of the experiment being conducted by Jane is to track the direction the outdoor sunflower heads were facing throughout the day.

The whole set up is designed to test the claim that sunflowers do follow the sun in the sky throughout the day.

From experiment, Jill should be able to track the changes in the orientation of flower head throughout the day.
This will rightfully support his claims .

kirill [66]

The biodiversity will decrease due to an increase in pollution is the effect will have on the biodiversity on the river ecosystem.

Option A

<u>Explanation:</u>

Biodiversity is the actual collection of total amounts of flora and fauna present in a particular ecosystem. The river ecosystem consists of the aquatic plants, the aquatic animals like fishes,etc and even the surrounding land plants and animals, who utilize the river water for their living.

The inclusion of the polluted sewage of the surrounding area into the river directly mixes several chemicals to the water, which are potentially harmful for all the animals living there. This leads to destruction of the flora and fauna of both water and lands surrounding them. This hampers the biodiversity of the water as well as surrounding land.
