I think the appropriate response is Target Heart Rate. It is prescribed that you practice inside 55 to 85 percent of your most extreme heart rate for no less than 20 to 30 minutes to get the best outcomes from vigorous exercise. The MHR (generally figured as 220 less your age) is the furthest reaches of what your cardiovascular framework can deal with amid physical movement.

A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessive for the t
Mumz [18]

Answer:

d. pxp +2pq

Explanation:

The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:

                           p² + 2pq + q² = 1

where, p = dominant allele

           q = recessive allele

Here,

 p² represents frequency of homozygous dominant genotype

2pq represents frequency of heterozygous genotype

q² represents frequency of homozygous recessive genotype

Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.

Explain how the theory of plate tectonics relates to the formation and breakup of pangaea
pshichka [43]
<span>Pangaea was the last of the great continents. Wegener hypothesized that all of the continents were one continent based on physical evidence that he collected. The shapes of the shores, matching mountain ranges and fossils/plants found on different continents. What Wegener did not have was the mechanism. Hess in 1963 discovered what is now called Mid-Ocean ridges. What accurs here is faults in the crust allow magma to move to the surface. The build up of magma, rift valeys leads to divergence of the plates moving apart. The continents began to pull apart and move away from each other. But as contnients move away from each other essentially they are also moving towards each other from another reference point. Now new have oceanic crust/plates moving towards continental plates leading to convergence. Look up the Wilson Cycle. It is like talking about what comes first, the chicken or the egg and if you do not look at the very beginning of earth it does not fully make sense.</span>
