Answer:
16) 6 electrons
17) 6 protons
18) 6 neutrons
19) 4 electrons
20) 6
Explanation:
There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.
This is based on my assumption that brown is dominant over blue.
Since both parent have parents who are homo_zygous recessive, this tells us that both parents will be hetero_zygous.
When you cross two hetero_zygous parents, it can produce these genotypic and phenotypic ratios:
<u>Genotypic</u>
BB : Bb : bb
1 : 2 : 1
<u>Phenotypic</u>
brown : blue
3 : 1
Therefore there is a 75% chance that they will produce a brown-eyed offspring.
Answer:
D. climax communities
Explanation:
The climax communities are the communities that have reached equilibrium. This basically means that there's the optimal number of species of flora and fauna, as well as the optimal populations of them in the ecosystem. They all interact and are perfectly adapted to coexist, benefit from one another, and balance the usage of food sources with its renewing. This type of communities appear at places where there has been no disturbances for quite some time, so the species lving there managed to create a perfect balance.
<span>The
difference in structure of the antennae and antennules is their size or length.
Antennae are long sensory organs while antennules are short or small sensory organs. These
organs are connected to the head of an insect, crab, or other animal and they
are used for taste, balance, smell, touch, air motion and vibration</span>
