Answer:
Type O
Expresses the B agglutinin
Expresses all the major antibodies
The most common US blood type
The universal donor
Type AB+
Expresses all of the major antigens
Expresses the D antigen
The least common US blood type
The universal acceptor
Expresses the Rh factor
Expresses A agglutinogen
Explanation:
Blood type is a grouping of blood into classes that have the presence or absence of antibodies and or antigens on the red blood cell surfaces
The class of blood determines whether the antigens are glycolipids, carbohydrates, proteins or glycoproteins of Type O
The blood type of a person is an inherited trait from both parental gene. There are various blood grouping system with the ABO and Rh systems being the most important as they determine the suitability of a given blood for transfusion.
Exocrine glands release secretions outside of the body.
One way to remember this is:
exo = outside
endo = inside
An example of an exocrine gland is a sweat gland. They release sweat (an excretion) to the outside of your body.

To test for the keystone species hypothesis, the wolves in another region can be removed or trees can be reintroduced to see the effect on the ecosystem.
<h3>What is a keystone species?</h3>
A keystone species is an organism whose existence defines an entire ecosystem such that them, the ecosystem would be severely affected or may not exist.
Trophic cascades are events which result in serious distortions in an ecosystem as a result of the removal or addition of a top predator.
To test for the hypothesis of keystone species and trophic cascades, the wolves in another region can be removed or trees can be reintroduced to see the effect on the ecosystem.

The correct answers are A and C.
When an individual is reproducing asexually, it means that there is no fusing of two parent cells and meiosis, but that the offspring is produced out of the cells of one parent. This means that the organism is not '' losing time'' by trying to find a suitable mate, which enables the populations to grow at a rapid rate.
However, the offspring are genetically identical to the parent, which means that there is very little genetic variation in the population which can lead to accumulation of harmful mutations and unresponsiveness to changes in the environment.
