<span>The catalyses enzyme is one of the most efficient enzymes known, since each enzyme can perform nearly 800,000 catalytic events per second. Catalase protects cells from hydrogen peroxide (H2O2) molecules by converting them to oxygen (O2) and water (H2O).</span><span />

Rachel ate a piece of fruit and happened to drop the seeds in her backyard. After a few weeks, she saw a small plant with flower
Dahasolnce [82]

The correct answer is angiosperms.  

The angiosperms, also known as the flowering plants, they are the most varied group of land plants with more than 400 families, and about 13000 known genera.  

Similarly to gymnosperms, the angiosperms are seed-bearing plants. However, they are separated from gymnosperms by the features like endosperm within the seeds, flowers, and the generation of fruits, which comprise the seeds.

In a certain group of African people, 4% are born with sickle-cell disease (homozygous recessive). In this case, only homozygous
ZanzabumX [31]

Answer:

32% of the population is heterozygous and resistant to malaria.

Explanation:

The population is in Hardy-Weinberg equilibrium, and according to the H-W principle:

a) Allele frequencies in a population are stable and is constant from generation to generation.

b) The gene pool remains constant.

c)  The sum total of all the allelic frequencies is 1

So mathematically this statement can be written as:

p2 + 2pq + q2 = 1

or p+q = 1

Where frequency of occurrence of allele "A" is p and of "a" is q (fothe frequr a gene of two alleles A and a)

p2 is the frequency of AA individuals

q2 is the frequency of aa individuals

2pq is the frequency of Aa individuals

Now in the question it is clearly given that 4% of the population has homozygous recessive disease condition, so q2 = 0.04; it implies q = 0.2

As we know p+q =1; so p = 0.8

The percentage of the population who are heterozygous can be given by 2pq = 2 * 0.2 * 0.8 = 0.32

=> 32% of the population is carrier for sickle cell anemia and at the same time resistant to malaria also.
