How has photosynthesis developed in different types of plants?

Biology
1 answer:
Evgesh-ka [11]3 years ago
3 0

Explanation:

Plants have been using light in this primal way for a large chunk of Earth's existence. But just how did they gain the ability to photosynthesize? The short answer is they stole it, about a billion and a half years ago, when single-celled organisms called protists engulfed photosynthesizing bacteria.

Give an example of how a biome is an open system from the point of view of the biosphere, atmosphere, lithosphere, and hydrosphe
Karolina [17]

Given what we know, we can confirm that the biome is in fact an open system due to the interactions between the biosphere, atmosphere, lithosphere, and hydrosphere.

<h3>What is the biome?</h3>
  • The biome is the collection of air, soil, water, and all the organisms that reside within these ecosystems.
  • In order to describe an open system, we say that the system must have external interactions.
  • A biome is an open system because it has both internal and external interactions, such as with asteroids in space.
  • The internal interactions include the ones between the<em><u> biosphere, atmosphere, lithosphere, and hydrosphere.</u></em>
  • A prime example is the movement of water through each of the spheres.

Therefore, since each part of the biome interacts with each other as well as with external sources such as space, we can confirm that it complies with the definition of an open system.

Species A has a diploid number of 42 chromosomes, while species B has a diploid number of 48 chromosomes. Give the chromosome nu
Arada [10]

Answer:

a. autotriploid of species A: 63 chromosomes

b. autotetraploid of species B: 96 chromosomes

c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes

Explanation:

<u>For a.</u>

this species will have 3 haploid sets of chromosomes ('tri' means 3)

one haploid set = 21

21 × 3 = 63 chromosomes

<u>For b.</u>

this species will have 4 haploid sets of chromosomes ('tetra' means 4)

one haploid set = 24

24 × 4 = 96 chromosomes

<u>For c.</u>

there are two ways to do this:

1) two sets of chromosomes from species A and one from species B

42 + 24 = 66 chromosomes

2) one set of chromosomes from species A and two from species B

21 + 48 = 69 chromosomes

Hope that answers the question, have a great day!

Recombinant DNA uses what medium to produce new genes?
mestny [16]

The genetic characteristic of two different organisms are induced into a new host organism for the purpose of producing new genes.

<u>Explanation:</u>

In the field of bio technology, Recombinant DNA technology plays a very important role. This helps in the production of genes. The first thing insulin of human was produced with this technology. In this technology, the gene that is to be produced is cut and it is placed inside a host organism where it gets multiplied.

This technology uses five steps in gene production. Firstly, the DNA that is essential will be cut. this is done by restriction site. PCR is used secondly in order to amplify the copies of the genes. Then these are induced into Vectors after which they will again be introduced into a host organism. Then finally the results will be the genes of the desired characteristics.
