The question is incomplete as it does not have the options which are:

A) chordate.

B) echinoderm.

C) nematode.

D) mollusc.

Answer:

A) chordate.

Explanation:

The animals can be distinguished based on embryonic development and are categorized into two types: Deutrostomes and the protostomes.

The deuterostomes are the organism in which the small opening in the embryo called the blastopore develops into the anus. The deuterostomes organism belongs to two groups of the animal: the echinoderms and the chordates.

The chordates are the animals which possess the bilateral symmetry that is can be divided into left and right sides and posses true cavity or coelom.

Thus, Option-A is correct.

Explain the relationship among
Iteru [2.4K]

Answer:

There is an important relationship among  homeostasis, defective mitochondria, and the  symptoms caused by LHON.

Explanation:

There is a great relationship among  homeostasis, defective mitochondria and the  symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.

Lynna [10]

Answer:

Malignant melanoma cells would have active telomerases that constantly replenish and lengthen telomeres.

Explanation:

Telomerase can be described as enzymes which add the repetitive sequences called telomeres at the end of a chromosome. Telomeres can be described as repetitive sequences at the end of the chromosome which are involved in protecting the chromosome from any damage.

In a normal skin cell, the telomeres will shorten with time. But in a malignant skin cell, the telomerase will add the repetitive sequence again and again. The telomers will not be able to shorten.

CAM photosynthesis limits CO2 fixation to nighttime hours in order to (A) allow water to enter leaf spaces during the daylight h
bixtya [17]

Answer:

(B) open stomata only at night, limiting water loss because of heat and low humidity.

Explanation:

CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.  

They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.  

During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.
