Answer:
The correct answer will be- Hydrolysis reaction
Explanation:
The metabolic reaction which involves the addition of water or the ions of the H₂O molecule which are the -OH and -H ions. Since these ions will be obtained through the hydrolysis of the water molecule, therefore, the process is known as the hydrolysis reaction.
This reaction is the opposite of the dehydration reaction in which the water molecule is released.
The breakdown of the polysaccharides into monosaccharides is a hydrolysis reaction.
Thus, Hydrolysis reaction is the correct answer.
Answer:
Easy.
1. The egg is made in the ovaries, and the sperm is made in the testes.
2.the egg goes down the fallopian tube and into the uterus, while the sperm goes upwards, they most often meet in the fallopian tube.
3.if the egg is not fertilized, the egg disintegrates and the body sheds the lining in the uterus, which results in your period.
Hope this is good!
Answer:
a. tryptophan levels are low.
Explanation:
Attenuation occurs when the tryptophan level in the cell is high so there is no need to synthesize tryptophan any more. In this situation, tryptophan mRNA synthesis comes to an end.
Attenuation is based on two following attributes:
(1) Translation dependent transcription
(2) Ability of RNA to assume alternative secondary structures.
Leader peptide is 16o nucleotide long region which contains 4 regions named as R1, R2, R3 and R4. In R1 region there are 2 tryptophan codons while after R4 region there is a polyU sequence. It it only after leader peptide, tryptophan biosynthesis genes are present in tryptophan operon.
When tryptophan levels in the cell are high, ribosome at R1 region immediately clears the region without any halt as a result of which R1 is able to pair up with R2 and R3 is able to pair up with R4 making a secondary structure i.e. hair pin structure. Soon after that there is a polyU sequence. This is a perfect condition for rho independent transcription termination.
This phenomenon helps in conserving the energy by inhibiting transcription in cell when tryptophan is not required because it is already present in abundance.
In contrast to this, when tryptophan levels are low, transcript is supposed to be transcribed so as to enhance the level of tryptophan in the cell. In such situation, the tRNA charged with tryptophan amino acid is in scarcity so the ribosome keeps waiting for this charged tRNA in R1. Since ribosome has occupied this region, R1 will be unable to pair up with R2. So R2 will pair up with R3. Since R3 has paired up with R2, it will not be able to pair up with R4. So a <u>secondary hair pin structure</u><u> </u><u>immediately followed up by polyU sequence will not form and hence transcription by RNA polymerase will go on. </u>

Answer:
Amphibians skin is fully functional in blood production, and become anemic when the skin is covered by fungus. Amphibians have small lungs and use their skin for respiration (Cutaneous Respiration); they suffocate when the skin is covered with fungal growth.
Answer:
D
Explanation: this would make sense because they could not have evolved to become the same. Evolution does not work like that . The animals would not walk or fly they are water creatures and if they did that they would not evolve back down to fish .
