Geneticist is a scientist that studies dna
Answer:
Prophase 1
Explanation:
In prophase 1, homologous chromosomes pair up and exchange sections of DNA in a process called crossing over.
<span><u>The answer is A. 72.25 percent.</u>
The Hardy-Weinberg principle can be used:</span>
<em>p² + 2pq + q² = 1</em> and <em>p + q = 1</em>
where <em>p</em> and <em>q</em> are the frequencies of
the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq </em>are the
frequencies of the genotypes.
<span>The <em>r</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15
To calculate the <em>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is
used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85
Knowing the frequency of the <em>R</em> allele (<em>p</em>), it is easy to determine the
frequency of the RR genotype (p²):
p² = 0.85² = 0.7225
Expressed in percentage, p² = 72.25%.</span>
Answer:
Mushrooms and plants all need energy to grow. But the sources of their energy differs.
Explanation:
Sun is the ultimate source of energy for any living organisms to grow and make their food. While plants takes energy from the sun directly and make their food, while the mushrooms which is not a plant does not take energy from the sun directly.
Mushrooms utilizes the energies which is collected by the different organism which collects their energy from the sun such as organisms like the bacteria and plants. Mushrooms grow well in darkness as darkness helps to retain moisture. Mushrooms does not have chlorophyll to make food.
Plants have chlorophyll. And they direct absorb energy from the sun light to make their own food.
