Archaebacteria and eubacteria are _____. A) prokaryotes B) eukaryotes

Answers

Answer 1

Answer: These both are prokaryotes, they do not have many membrane bound organelles. Their DNA is found in the nucleoid (no membrane), not the nucleus.

Answer 2

Answer: While both archaebacteria and eubacteria areprokaryotic, they are evolutionarily different. All prokaryotic cells are unicellular, have a cell wall and lack both a nucleus and membrane-bound organelles.

Correct Answer is (3)

Explanation:

(3) In order to survive, all organisms must carry out enzyme-controlled reactions.

Enzymes is the Most of the responses that happen in living life forms are chemical controlled.
They are along these lines explicit in the responses that they catalyze one chemical will respond with particles of one substrate.
The site of the response happens in a territory on the outside of the protein called the active site.
Enzymes can be influenced by an assortment of elements, for example, temperature, pH, and focus.
Chemicals work best inside explicit temperature and pH ranges, and imperfect conditions can make a protein lose its capacity to tie to a substrate.
The most of the enzyme has an optimum pH range.

Why does the predator line lag behind the prey line?

Answers

The prey are the food source. When the prey numbers are plentiful, there comes a period of time when the predator begins producing offspring to capitalize on the abundant food source. Offspring cant survive unless there is plenty of available food.

Which of the following is true?(A) Protein-coding genes make up far less of the human genome than noncoding DNA.
(B) Protein-coding genes and noncoding DNA make up about the same amount of the human genome.
(C) Protein-coding genes make up far more of the human genome than noncoding DNA.
(D) Noncoding DNA has not been found in humans.

Answers

Answer:

(A) Protein-coding genes make up far less of the human genome than noncoding DNA.

Explanation:

The human genome contains both protein-coding and non-coding sequences. However, the non-coding sequences make most of the human genome as they account for as much as 98.5% of the total human genome. The non-coding part of the human genome serves other important functions such as promoter, enhancers, silencers for gene expression.

An only small part of the human genome serves as protein-coding genes and make exons.

What are the three basic functions organs perform in the human body

Answers

Answer:

The answer is: Nutrition, Relationship, Reproduction.

Explanation:

Vital functions are those that are necessary to live, without them we would die.They are divided into functions: nutrition, relationship and reproduction.

Nutrition: they are related to the respiration and nourishment of the cells: respiration, nourishment, blood circulation and excretion.

Relationship: they are related to the control of the body by the brain and nervous system.

Reproduction: it is not vital for an individual but reproduction is necessary for the conservation of the species.

The answer is: Nutrition, Relationship, Reproduction.

A symbiotic relationship in which one species benefits and the other is harmed but not immediately killed is known as?

Answers

Answer:

Parasitism.

Explanation:

A biological interaction explains the different relationship between the organism and their interaction in the environment. The different biological interaction are mutualism, ammensalism and parasitism.

Parasitism may be defined as the type of symbiotic relationship in which the organisms are associated with each other. The one species gets benefit from the other organism while the other organism is harmed but they are ot killed directly or immediately. This is a type of negative interaction.

Thus, the answer is parasitism.

It's called parasitism.
