Answer:

The correct answer would be C) All organisms in the domain have eukaryotic cells.

There are mainly three domains in biological classification namely; Archaea, Bacteria, and Eukarya.

Archaea includes all the prokaryotic cells which are characterized by their lipid membranes. They have branched hydrocarbon which is attached to glycerol through an ether linkage.

Bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. In addition, they are attached to glycerol through an ester bond.

Eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

They can be autotrophic as well as heterotrophic, unicellular as well as multicellular

They include kingdoms like Protista, Plantae, Animalia, Fungi et cetera.

Fofino [41]

<u>Answer:</u>

<em>B. Many genetic diseases would be curable. </em>

<u>Explanation:</u>

Gene therapy is intended to acquaint hereditary material into cells in order to compensate for faulty or mutated genes or to make a helpful protein. On the off chance that a faulty gene makes a beneficial protein be flawed or missing, gene therapy might have the option to present a typical duplicate of the gene to reestablish the function of the protein.  

A gene that is embedded straightforwardly into a cell as a rule doesn't work. Rather, a bearer or carrier called as a vector is hereditary built to insert the desired gene.

Why is a person with type AB blood able to receive a blood transfusion from a donor with any of the major blood types (A, B, AB,
Alisiya [41]

Answer:

ABO blood grouping system is based on presence or absence of three types of antigen on red blood cells. A and B blood group have A and B antigens respectively. AB blood group has both A and B antigens. O blood group does not have any antigen.

A body with particular blood type will consider other blood group foreign ( because it has different antigen ) and produce antibodies against it. A person with blood type A can not be given B type blood because the antibodies in his body will destroy RBCs with B antigen which may even prove fatal.

AB blood type person can receive blood from both A and B blood groups because he has antigens for both of them so it will produce antibodies for neither of them. He can also receive O type blood because O blood does not have any antigen so it can be given to any person without incompatibility reaction.  

However, AB individual can only donate blood to AB individual because his blood cells have both A and B antigens. So, he can only donate blood to an individual who does not produce antibodies for both A and B blood groups and that would only be another AB blood type individual.

Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.
Svetlanka [38]

Answer:

competition

Explanation:

An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).

A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.

Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.
