What evolutionaryadaptation allowed plantsto grown large and abovewater?​

Anna35 [415]2 years ago

Evolutionary adaptations like fertilization, cuticle, stomata, and vascular tissue helps plants to grow on land.

<u>Explanation:</u>

There are various ways through which plants evolved and grown above water. First is that in plants, the embryo develops inside the female body after the process of fertilization. Second, with time, the cuticle helped the plant to seal water and prevent water loss.

Stomata evolved with time to retain water and exchange gases — lastly, the vascular tissue which is responsible for transporting water, food, and nutrients in plants

For each of the following statements, indicate
stepan [7]

The plants that were allowed to self pollinate were the F1 plants.

The plants that are true breeding are P generation plants.

The plants where there were 3times as many tall plants as short plants are in F2 generation.

<h3><u>Explanation:</u></h3>

This question is based on the Mendel’s Experiment. Sir Gregor Johann Mendel was the father of genetics who experimented on garden pea plants <em>Pisum</em> <em>sativum</em> to see whether the characters got mixed or not and to know the real cause behind different traits of same character in plants.

He took the pure homozygous tall and short plants separately which he called as parental generation or P generation. These plants were homozygous, hence pure breeding.

As these plants were crossed between themselves, then the F1 generation showed all tall plants. This is because of the heterozygous plants which showed character of dominant trait. These plants were allowed to self pollinate.

As a result of self pollination of the F1 plants, the F2 plants were 75% tall in number whereas the other 25% short, which gave the phenotypic ratio of 3:1.

What name is given to the monomers of proteins? fatty acids monosaccharides amino acids nucleic acids
Ghella [55]

Answer:

The correct answer is amino acids.

Explanation:

The organic compounds, which associates together to produce proteins are known as amino acids. The proteins and amino acids are the building blocks of life. At the time of the digestion or dissociation of proteins, amino acids get left. A huge ratio of the muscles, cells, and the tissues are formed of amino acids, which shows that they conduct various essential functions of the body like providing cells their composition.

Answer:

sympatric speciation

Explanation:  

Different sympatric species have the same closest ancestor and live in the same area but inhabiting different niches.

The steps for sympatric speciation are:

  1. An ancestral species inhabit a geographic area.
  2. With time, different populations of the same species occupy different niches or microhabitats in this general area.
  3. As the microhabitats are different, they have different environmental pressures that are acting on each population.
  4. These pressures lead to the origin of differences between groups, which need to adapt to each environment
  5. Each population suffers genetic changes due to environmental conditions. These changes are inheritable.
  6. With time, these differences drive to the final complete divergence of populations, becoming different species and reproductively isolated.

In sympatric speciation, the interruption of genetic flow must be fast, and there must be differences in niches so no species can compete and displace the other species. <em>Speciation occurs in the same distribution area of the original species</em>. The new species originate in a place with no physical barriers but different environmental pressures.

In the exposed example,

  • <em>The introduced Cichlid fishes 200 years ago</em> → Original species and the common ancestor between the new derivated species
  • <em>The lake</em> → general geographic area
  • <em>The main lake and the streams</em> → Microhabitats or niches with different pressures each
  • <em>The groups are splitting into two genetically and physically different types of fishes. They do not mate. There is no genetic flow between groups.</em> → Speciation process.
