What happens to the size in each level in the idealized pyramid as energy is transferred through the trophic levels?

Biology
1 answer:
Fed [463]3 years ago
4 0

Answer:

The size is reduced as 80-95% of the available energy at one trophic level is not transferred to the next

Explanation:

There is loss of energy as it is transferred between trophic levels. The decrease in energy as it moves up the pyramid is due to energy loss as metabolic heat when one organism is consumed by another from the next level as it moves up the trophic levels.

Antibodies are composed of two types of peptides, heavy chains and light chains. One of the major classes of antibody molecules
timurjin [86]

Answer and Explanation:

a. form the antigen-binding site ⇒ both chains

The antigen-binding site is formed by one hypervariable region of the light chain (VL) and one hypervariable region of the heavy chain (VH). So, both type of chains contributes to antigen recognition.

b. contain multiple variable domains ⇒ none

Both chains - light and heavy - contain <u>only one</u> variable domain (VL and VH).  

c. are found in the Fab fragment ⇒ both chains

The Fab fragment is composed of portions of both light and heavy chains: each portion contains one variable domain and one constant domain. The Fab fragment binds specifically the antigen.  

d. are found in the FC fragment ⇒ heavy chains

The Fc region is composed of portions of heavy chains (CH² and CH³), so it contains constant domains.  

e. contain only one constant domain ⇒ light chains

Each light chain contains one variable domain (VL) and one constant domain (CL).  

f. contain multiple constant domains ⇒ heavy chains

Each heavy chain contains three constant domains: CH¹, CH² and CH³.  

g. contain only one variable domain ⇒ both chains

Both light and heavy chains contain one variable domain. The difference is given by the number of constant domains: light chains have 1 constant domain while heavy chains have 3 constant domains.

The Lincoln family has 3 children, 1 girl and 2 boys. What is the probability that their 4th child will be a boy?
goldfiish [28.3K]

Answer:

1/2

Explanation:

You have a 1/2 chance of having a boy and a 1/2 chance of having a girl.

Unless the question specifies whether or not there is a mutation present with the male parent, it is safe to assume there is a 50/50 shot of having a boy or girl.
