Answer: Chordates

Explanation: Ascidiacea belongs to the phylum Chordates. They are characterized by outer hard covering known as tunic which is made up of polysaccharide cellulose.

They are found all over the world, usually in the shallow water. They are sac like marine animals. They are invertebrates having almost 2300 species.

Example: sea squirts.

Ketone bodies, the byproduct of fat metabolism, if found in the urine can be indicative of what life threatening disorder?
Ugo [173]

Answer:

uncontrolled 1 diabetes mellitus.

Explanation:

Keto bodies elevation of the urine is due to:

1.non availability of glucose in the blood to be used by the cells for biochemical activities,

OR

GLUCOSE can not enter cells because of absence of INSULIN hormone which moderate GLUT TRANSPORTERS 1 and 4 for entry of glucose into cells in induvidual with Type 1 diabetes.

TYPE 1 diabetes is a condition where the pancreas beta cells refused to secret hormone insulin,therefore affecting the entry of glucose into cells. Leading to elevated blood glucose level,and loss in the urine (Hypoglycemia from polyuria(too much urination.)Because the primary function of insulin is to facilitate the uptake of glucose into cells.

In this induvidual the liver converted excess tryglycerides to glucose in a process called GLUCONEOGENESIS(. The prouction of glucose from non carbohydrate compounds.)

The metabolized lipids leads to build up of byproduct ketone bodies in the blood.This produce ketosis and later progress to Ketoacidosis or metabolic acidosis

A single celled organism can be classified as a prokaryote based on the absence of
DIA [1.3K]

Answer:

Nucleus

Explanation:

Prokaryotes are the singled cell organisms that do not have a true nucleus which means like eukaryotes they lack a membrane-bound nucleus. So the genetic material of prokaryote are present in the cytoplasm of their cell.

Apart from the nucleus prokaryotes also lack membrane-bound organelle like mitochondria or chloroplast which are present in eukaryotes and helps in ATP formation for the cell. So prokaryotes use the plasma membrane of cell for production of ATP.

Therefore an organism can be classified as a prokaryote if it lacks a nucleus and other membrane-bound organelles.

How does sexual reproduction compare to DNA transfers in prokaryotes? (2 points)
Andreyy89

Answer:

The correct answer is b. I and II

Explanation:

Sexual reproduction is present in higher forms of life and absent in prokaryotes like bacteria. Sexual reproduction results in greater evolutionary changes due to the fusion of two different gametes from two different individuals of a species.

Therefore sexual reproduction helps in increased genetic diversity in higher forms of life. In prokaryotes like bacteria, genetic diversity is maintained and increased through DNA transfer from one bacterial cell to another with the help of a process known as horizontal gene transfer.

Bacteria have sex pilli which is used to introduce the genes to the other bacteria. By this process, they increase their genetic diversity and evolve continuously. So the correct is b. I and II.
