Answer:
Primary consumers are the organisms that feed directly on the autotrophs to obtain energy. These consumers thus help to transfer energy to higher trophic levels that are secondary consumers. An example is the goat feeding on a plant is a primary consumer that directly obtains its energy from the plant.
Explanation:
Cross cultural studies or which can be called ethology is important in studying behavioral biology because ethology is the scientific and objective study of an animal well particularly focuses on its behavioral under natural conditions and viewing behavior as an evolutionary active trait. in some ways we can adopt the learning in this study to what we have.
Plant cells, and some protists.
The surviving children would be 66.7% female and 33.3% male. Of the female children, 50% would be expected to be carriers of this gene (like their mother)
| Xg | X
—————-
X | XXg | XX
—————-
Y | XgY | XY
Pretty ugly, but the best punnet square I can do without a link. The offspring with the “g” are those that carry the lethal gene. The male child that carries it will die, but since it is recessive, the female child will live but will be a carrier for this gene. I hope this helps.
The answer is <span>5.2 × 10-2 newtons.
To calculate this, we will use Coulomb's Law:
</span>F =
where F is repulcive force, k is constant, Q is charge, r is distance between charges.
<span>
If:

C²
r = 5.0 ×
C²
k = 5.0 ×
Then:
