Answer:

As a metabolic heat.

Explanation:

The loss of energy from one trophic level to the next in a food chain occurs because energy is lost in the form of heat when the organisms from one trophic level are consumed by organisms from the next level. Only 10% of energy is transferred from one trophic level to another while the remaining 90% energy is lost in the form of heat energy in the ecosystem.

What is the probability that a seed from a parent plant of genotype Rr will carry the r gene
daser333 [38]
The answer is 50 percent.

Parent plant of genotype Rr will in meiosis produce haploid gametes which will carry either R allele or r allele. Since there are only two possibilities R or r, the probability that seed will get r gene is 1 of 2. This can be presented as 1/2, which is 50%.

<h3>What is eukaryotic cell?</h3>
  • Eukaryotes are organisms having cells that contain a nuclear envelope around their nucleus.
  • They are a member of the Eukaryote class of organisms.
  • One of the three domains of life is the eukaryotic domain.
  • The other two are the bacterial and archaeal domains.
  • Organisms called eukaryotes have nuclei and membrane-bound organelles in their cells.
  • Eukaryotic creatures come in a great variety, including most algae, all animals, plants, fungus, and protists.
  • Eukaryotes are multicellular or unicellular organisms.
  • The primary distinction between these two categories of organisms is that eukaryotic cells have a membrane-bound nucleus while prokaryotic cells have not.
  • The nuclei of eukaryotes house their genetic material.

plz help!!! If this is a sequence of one DNA strand, what is the complementary sequence of the other DNA strand? DNA: A T T C A
gizmo_the_mogwai [7]

Answer:

T A A G T C G C T

Explanation:

DNA strand:                             A T T C A G C G A

complementary DNA strand:  T A A G T C G C T

This is a very important rule:

Four kinds of nitrogenous bases in DNA: Adnine (A), Thymine (T), Guanine (G), Cytosine (C)

And this is how they're coupled:

A = T

C = G

For example::

First DNA strand:                  A T G C

complementary strand:        T A C G
