How does the colour of star help to find its age​

Biology
1 answer:
Finger [1]3 years ago
4 0

Answer:

As stars age, they run out of hydrogen to burn, decreasing the amount of energy they emit. Thus, younger stars can appear bluer while older ones appear more red, and in this way, a star's color can tell us something about that star's age.

Describe the effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases
Scrat [10]

Answer:

The effect of amanitin on the maximum elongation rate for the wild-type and modified RNA polymerases is that it binds to the RNA polymerases, and reduces the process of translocation which is essential for RNA synthesis that is required for RNA polymerases elongation.

Explanation:

Amanitin is a peptide that is cyclic in nature. It is repelled by water thereby making it an hydrophobic peptide.

Amanitin is a toxic peptide that is found in Amanita ( a type of mushroom).

Alpha Amanitin in particular is the one that affects the elongation rate of RNA Polymerases in the body.

When Alpha Amanitin gets into the body system, it travels straight to the liver and due to its very strong affinity for RNA polymerases, it immediately attaches itself to them.

After the attachment, Alpha Amanitin, is disturbs the bridge helix found in RNA polymerase, preventing the hindering and slowing down the proces of translocation from happening.

Once translocation is hindered, RNA is no longer synthesized. Hence, the elongation of RNA polymerases is hindered and this results in severe illness in the body such as liver failure, cytolysis of the liver

What must take place in the lungs prior to the newborn's first breath? A. Blood must be drained from the alveolar capillaries B.
Iteru [2.4K]

Answer: Drainage or absorption of amniotic fluid

Explanation: Amniotic fluid act as a cushion to a growing foetus and provides the foetus with nutrients and biochemical products from the mother via the blood vessels of the placenta. When the date of baby delivery grows closer the lungs absorbs some of the fluid. Soon after birth the newborn's first step to independence begins with breathing on its own.They gasp and cry taking in air that fills the lungs. This expels the remaining amniotic fluid that was in the lungs and begins its own independent breathing.
