Answer:

The correct answer is - C. It showed that different-looking animals are actually related.

Explanation:

DNA technologies help in developing the lineage of the organisms and more use of cladistics. DNA techniques help in determining which animals were closely related by studying the genetic change.

It is used to established new evolutionary relationships between different-looking animals as minor genetic changes may lead to morphological changes.

Answer:

Venus, I think

Explanation:

So outta these three, Venus is the closest to the sun, so the year is the shortest. Venus is also the planet with the longest day averaging at 116d 18h, so I think that's the right one. Sorry if this is wrong

Answer:

The correct answer is - sister chromatids are separated.

Explanation:

Meiosis is divided in two parts meiosis I and meiosis II. In the later part that is meiosis II is characterized by forming four haploid gametes by separating the sister chromatids in the two daughter cell.

Crossing over takes place in meiosis I that leads to recombination and reduces the chromosome number from diploid to haploid homologous chromosomes and then enters into meiosis II.

Yellow color is always an adaptive trait in a yellow environment I agree with this claim.

Adaptive trait is defined as an element of the developmental pattern that makes it easier for its carrier to survive and/or reproduce in a succession of different situations.

Any heritable characteristic that enables a plant or animal to survive and procreate in its environment is referred to as an adaptation.

The process of modifying behavior, physiology, or structure to make it more suitable to an environment is known as adaptation.

It might also be described as the condition that a biological population has achieved after enduring modifications or changes.

There are three types of adaptive traits.

Thus, yellow color is always an adaptive trait in a yellow environment I agree with this claim.

Answer:

The correct answer is - Sugars produced in the leaves are used as an energy source instead of being stored in fruits.

Explanation:

The high temperature in climate leads to an increase in the respiration rate in the plants so they require more energy in the process.

They produce sugars in the leaves which leads to a decrease in the sugar content in the fruit as energy is the primary focus in such situation to survive in high temperatures.

Answer:

The rain containing excess of acids called an acid rain.

Explanation:

The rain becomes acidic because of harmful gases like carbon dioxide,

sulphur dioxide and nitrogen dioxide which are emitted as smoke from

vehicles and industries. These harmful gases dissolve in rain drops to

form carbonic acid, sulphuric acid and nitric acid respectively.

Effects of Acid Rain

 Acid rain makes the water of lakes, ponds and rivers too acidic

due to which fish and other aquatic animals get killed.

 Acid rain eats up the leaves of the trees gradually. By losing

leaves, the trees die. Acid rain also damages crop plants in the

fields.

 Acid rain damages the metal structures like steel bridges, etc

when it falls on them.

 Acid rain damages the surfaces of buildings and monuments made

up of marble.

Heterozygous means having two different alleles.

Answer:

Heterozygous individuals have two different alleles of a gene.

Explanation:

Answer:

A. Grass

Explanation:

In their natural habitat, organisms feed on one another in a relationship called PREDATION. Predation involves two organisms; one called the PREDATOR (the organism that eats) and the other PREY (the organism being eaten).

Organisms preying on one organism will naturally opt for a substitute once the previous prey is no longer accesible. This is the case of a fungus-infected corn that is no longer edible for predators. Hence, the predators will hunt similar feed, which is GRASS in this case.
