Dmitry_Shevchenko [17]3 years ago
7 0

Answer:

4

Explanation:

In the food chain that is presented there are four trophic levels. The first level is occupied by the phytoplankton, which is the producer, thus it is at level one on the energy pyramid. Second comes the shrimp, which is feeding on phytoplankton, but is prey upon by numerous other species, thus it is on the second level in the energy pyramid. In the third level of the energy pyramid we have the perch. It is a small carnivore, and it feeds upon the shrimp and many other small prey animals, but it is also preyed upon by many larger species. The pike and the osprey are occupying the fourth level in the energy pyramid. They are both predators, and they prey on on the likes of the perch and many other small fish and animals, but they are not at the top of the food chain, as they also have predators above them and prey on them.

Two offspring from same parents can have different phenotypes. How is this possible?​
Mama L [17]

Answer:

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

Analyze and conclude 7. which, if any, of the blood samples tested cna the patient with type b+ blood receive? explain why. 8. e
Digiron [165]
<span>7. which, if any, of the blood samples tested cna the patient with type b+ blood receive? explain why.
It can't be answered because you didn't put the sample test result


8. explain how you were able to use your knowledge of how different types of blood react with anti-a, anti-b, and anti Rh antibodies to determine the blood types of the four samples.
If the blood react with anti-a, then the blood must not have A antigen
</span>If the blood react with anti-b, then the blood must not have B antigen
If the blood react with anti Rh, then the blood must not have Rh antigen
Based on the antigen, you can conclude the result as:
react with anti A= blood type B
react with anti B= blood type A
react with anti A and anti B= blood type O
react with anti Rh= Rh-
not react with anti Rh= Rh+
<span>
9. if a person has type a blood, he or she would have antibodies for what blood type?
Type A blood has antigen A. So that person should not have anti-A antigens. 
The person should have anti-B antibodies because it was a foreign object to him. Depends on the Rhesus type, he can have Rh antibodies too.

10. why is type o negative blood known as the universal donor? why is o positive not a universal donor?

Type O blood doesn't have antigen-A or antigen-B. That means the blood cells won't trigger any reaction on Type A, B, AB, or O blood. Negative rhesus also means that the blood is safe for Rhesus negative or Rhesus positive type. 

Positive O blood type has rhesus antigen, so it will trigger a reaction in Rhesus negative type. </span>

What differentiates anthropocentric and biocentric views of the environment?
Dafna11 [192]
If we were to differentiate anthroprocentric and biocentric views of the environment you could say that anthroprocentric is more holistic than biocentric. They consider the importance of the environment to human beings. Biocentric sees humans as an individual part of the environment.

Also Biocentric views tend to focus more on biotic factors (living things) and anthroprocentric veer towards the abiotic factors (non-living things).
