Answer:
d.0.48
Explanation:
When a population is in Hardy Weinberg equilibrium the <u>genotypic </u>frequencies are:
freq (AA) = p²
freq (Aa) = 2pq
freq (aa) = q²
<em>p</em> is the frequency of the dominant <em>A</em> allele and <em>q</em> is the frequency of the recessive <em>a</em> allele.
In this population of 100 individuals, 84 martians have the dominant phenotype and 16 have the recessive phenotype.
Therefore:
q²=16/100
q² = 0.16
q=√0.16
q = 0.4
And p+q=1, so:
p = 1 - q
p = 1-0.4
p = 0.6
The frequency of heterozygotes is:
freq (Aa) = 2pq = 2 × 0.4 × 0.6
freq (Aa) = 0.48
The correct option is C.
The heart is part of the cardiovascular system. The heart pump the blood round the body several times in a day. The blood is made up of several types of cells which carry out specific function in the body, these include the white blood cells which serves as soldiers of the body. The lymph refers to the fluid that circulate throughout the lymphatic system. Both the blood and the lymph are carried round the body by the cardiovascular system during the process of circulation.<span />
Answer:
Trees have to adapt to their environments in order to survive them, from the shape of their leaves to the size of their branches. They also have had to adapt the shape of their crowns to the kind of climate they live in so that they may have better chances at survival.
In warm areas with lots of sunlight for instance, you will see broad cones as the tree takes advantage to get as much sunlight as it can. In colder areas where snow is abundant, trees will be conical in shape so as not to gather too much snow when it falls.
Answer:
mass
Explanation:
because the unit kg is S.I unit of mass
Base on one of the Law of Thermodynamics, the amount of available energy decreases whenever energy is changed in form (which includes a transfer from one trophic level to another). So, as we go from the first trophic level to the top trophic level, the amount of available energy becomes less and less.
