Why do you think some flora and funna get extinct from the earth
Answers
Hey, there!!!!
The main reasons for the extinction of flora and fauna are:
- The climate change is one main reason for extinction of various flora and fauna.
- Unwanted urbanization has also destroyed many flora and fauna.
- Hunting of fauna cause loss of various type of species of fauna and overgrazing or afforestation has caused destruction of plants species.
Hope it helps...

The correct answer is explained below:
Explanation:
- According to the question,
- The dominant allele for the photic response gene is: H
- The recessive allele for the photic response gene is: h.
- It is said that both the man and the woman are heterozygous for the photic response trait, that is, both of them have the Hh genotype.
- Both sneeze when exposed to bright sunlight, hence both of them show the photic response phenotype.
- This means the photic response trait is a dominant trait.
- Gametes produced by both the man and woman are: H and h.
- Mating the man with the woman, we get offspring with the following genotypes and phenotypes.
H h
H HH Hh
Photic Response Positive Positive
h Hh hh
Photic Response Positive Negative
- From the above Punnett square we get,
- Percentage of offspring expected to show photic response trait =
%.
- Percentage of offspring expected to not show any photic response trait =
%.

Answer:
The presence of DNA, RNA, and membrane components suggest that the cell was destroyed during the process of secretion. This is consistent with a holocrine type of secretion.
Explanation:
Holocrine is a term used to classify the mode of secretion in exocrine glands in the study of histology. Holocrine secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane, which destroys the cell and results in the secretion of the product into the lumen. Skin glands in mammals are classified into holocrine (e.g., sebaceous glands), and merocrine (e.g., sweat glands). The sub mandibular or chin gland of rabbits is a modified sweat gland (apocrine; Lyne et al., 1964) developed from the external root sheath of the hair follicle and attached to it
Final answer:
The secretion described is likely an 'apocrine secretion', a type of glandular secretion involving the release of cytoplasmic materials. This process includes the release of DNA, RNA and membrane components like phospholipids.
Explanation:
The secretion you've described is most likely an instance of a cell's apocrine secretion, which is a form of glandular secretion that involves the release of cytoplasmic materials. In this type of secretion, parts of a cell's cytoplasm (which contains DNA and RNA) are pinched off into the secretory vesicle, along with membrane components like phospholipids. Once the vesicle reaches the cell surface, it fuses with the plasma membrane and the contents are released outside the cell. This type of secretion is common in mammary glands and some sweat glands in humans.

Final answer:
During transcription, an mRNA molecule which is a copy of the gene of interest is produced. This mRNA molecule is then sent to the cytoplasm where it undergoes translation to produce a sequence of amino acids that form a protein.
Explanation:
During the process of transcription, an mRNA molecule (messenger RNA) is produced inside the cell nucleus. This molecule is a transcript, or copy, of a specific DNA sequence, specifically the gene of interest. The mRNA is then modified and sent into the cytoplasm for translation, which is the next step in protein synthesis.
The transcription follows three main stages: initiation, elongation, and termination, much like DNA replication. However, instead of replicating the whole DNA strand, only a small portion is transcribed. The resulting mRNA contains the four bases adenine (A), cytosine (C), guanine (G), and uracil (U), replacing the thymine found in DNA.
The translation of the mRNA template then happens, converting the genetic information into a sequence of amino acids that form a protein. This process is carried out by ribosomes and tRNA molecules in the cytoplasm.
