Which process mitosis or meiosis repairs skin following sunburn

1 answer:

5 0

The answer is mitosis.

Mitosis and meiosis are both 2 different kinds of cell division process. In mitosis, a parent cell will divide and produce 2 daughter cells that are genetically identical to both the other daughter cell and the parent cell. Since this process produces identical cells, it is mostly used in growth, tissue repair etc.

On the other hand, meiosis is the cell division process where a parent cell produces 2 daughter cells, and the two daughter cells produces 4 more daughter cells, and these daughter cells are genetically different to each other, they only have half of the chromosomes than its parent cell. Meiosis is used in producing gametes, so that when 2 gamete fuse together, in fertilization, the zygote can retain the correct amount of chromosome.

Therefore, since skin is not used in reproduction and its chromosomes should be the same as the original skin cell, mitosis is the answer.

What are the structural and functional similarities and differences between mitochondria and chloroplasts?

Sveta_85 [38]

Answer:

Similarities between Mitochondria and Chloroplasts-

Both mitochondria and chloroplast consists of DNA , have two membranes, have fluids inside them and convert energy.

Difference between Mitochondria and Chloroplasts-

They have different number of compartments, have different functions, and are involved in different energy processes.

Explanation:

Difference in Mitochondria and Chloroplasts-

a) Chloroplast is found in plants and unicellular organism and Mitochondria is found all cells.

b) Chloroplast converts solar energy into chemical energy while Mitochondria converts one form of chemical energy into other form of chemical energy

c) Chloroplast is involved in photosynthesis while mitochondria is involved in cellular respiration.

d) Chloroplast has three parts i) Thylakoid ii) stroma and iii) granum while mitochondria has three parts i) Critsa ii) Matrix

Similarities between Mitochondria and Chloroplasts-

Both mitochondria and chloroplast consists of DNA , have two membranes, have fluids inside them and convert energy.

Scientists use DNA sequencing to understand relationships among life on Earth. The chart illustrates differences between five sp

OlgaM077 [116]

Answer:

With respect to the differences in the DNA sequence of six species, including the human one, it is true that the DNA sequences may vary but the aminoacid sequences are identical.

Explanation:

Options for this question:

The DNA sequences may vary but the amino acid sequences are identical.
The nitrogen bases in the nucleotides must also be different in each.
The process in producing additional DNA, replication, is identical in all six.
The process of producing DNA, or replication, varies due to the differences in the DNA codes.

The different species that exist have specific genomes for each of them, this is the genetic information contained in the DNA varies from one species to another, as can be seen in the scheme (see image). However, the genetic code is universal, and does not vary from one species to another.

The genetic code is found in the RNA molecule and is a sequence of nucleotides that, organized in triplets (codons), are responsible for the synthesis of specific amino acids. An RNA molecule contains the information necessary for protein synthesis.

The scheme shows the differences of five species with respect to the human, based on the respective DNA sequences. But what it does not show is a universally accepted truth, that the nucleotide sequence encoding an amino acid is the same for each of these species.
