I think the correct answer from the choices listed above is option A. A single population is made of multiple organisms. In biology, population is a group of individuals which belongs to the same species that lives in the same area. Hope this answers the question.
The answer is; B
This type of inhibitors does not bind the active site of the enzyme hence does not compete with the substrate (hence its name non-competitive inhibitors). They bind the enzyme at another site and change its conformation. The substrate may still be able to bind the active site but the efficiency of catalysis can be drastically reduced threatening life. This type of inhibition cannot be cured by increasing substrate levels.
Ovulation is the process in which eggs are released from the ovary.
Answer:
Tay Sachs
Explanation:
Tay Sachs is a neurodegenerative disorder caused by the deficiency of enzyme hexosaminidase A in lysosome. Lysosome is responsible for degradation of lipid molecules which it carries out by the help of hexosaminidase A enzyme. In absence of the functional enzyme, lipids build up in lysosome which ultimately damages the cell and the tissue. Nerve cells are damaged the most in this disorder.
It is an autosomal recessive disorder which means that the mutant allele must be present in two copies for the production of symptoms. Symptoms are hypotonia, psychomotor regression etc. Its frequency is much higher in Jewish people of Ashkenazi descent. 1 in 30 Ashkenazi Jewish people has the mutant version of the gene.
Answer:
One distinguishing characteristicof all three clades i.e Deuterostomia, Lophototrochozoa, or Ecydysozoa are balstopore development, internal body cavity and exoskeleton respectively
Explanation:
Apart from molecular difference, there exist structural differences between the three clades, which are as follows –
Deuterostomia – The development of embryo is different from the protostomes as the first opening in this clade is anus and the blastopores develops into the anus.
Lophototrochozoa – They do not have ant distinguished internal body cavity. Organs with in coelom can move freely. For example - flatworm
Ecydysozoa – have the ability to shed their tough and flexible exoskeleton i.e cuticle , several times throughout their life span
