Answer:

The earth rotates on its axis in anticlockwise direction, the angle of sun rays produces seasonality.

Explanation:

  • It's a fact that the amount of solar intensity and daylight varies form place to place on the surface of the globe as the earth is not flat nor it's completely a sphere.
  • As it has bulges around the equator that is a greater circle which gets most of the annual sunlight at 90° angle and is due to its location in tropics.
  • While the places located near the poles have fewer hours of sunlight as of low duration as the rays of the sun take more time to moves from a low angled path. These north and south poles are impacted by seasonality and have 6 months of day and night.

What can the reader conclude about homeostasis?
myrzilka [38]
Without external and internal stimuli, your body would not be able to maintain homeostasis. Homeostasisis a property of systems that regulates their internal environment (blood levels, temperature, nutrient levels, etc.) and tends to maintain a stable, constant condition despite changing external conditions.

EleoNora [17]
<h2>look at the Y chromosome is the strategy  </h2>

Explanation:

  • Finally, it is possible that front line individuals do pass on at any rate one mtDNA heredity that Neanderthals added to our genome, in any case, that we have not yet sequenced that family line in either modern individuals or in Neanderthals. Any of these explanations could underlie the nonappearance of Neanderthal mtDNA in modern human population.
  • Because the y chromosome inherited by paternally and mitrochondrial DNA identify the case of maternity, or parents where it helps to the person for confirmation of genome and the child parents.
  • look at the Y chromosome because it is paternally inherited is the correct answer.

miv72 [106K]

Answer

CR = 0.7, Cr = 0.3, the genotype ratio is what would be predicted from these frequencies and the population is in equillibrium since the sum of both the frequencies is equal to 1 which is a condition for hardy weinberg equilibrium.

Explanation:

n a random sample of a population of shorthorn cattle, 73 animals were red (CRcR), 63 were roan, a mixture of red and white (CRC), and 13 were lele freauencies of C and C", and determine whether thepopulation is white (C'C). Estimate the al in Hardy-Weinberg equilibrium. 0.36; because the population 1s arge and a random sample was chosen, the 0.64, Cr population is in equilibrium. 0.7, C 0.3; the genotype ratio is n what would be predicted from these frequen- cies and the population is not in equilibrium. CR 0.7, C0.3; the genotype ratio is what would be predicted from these frequencies and the population is in equilibrium. С" 1.04, 0.44; the allele frequencies add up to greater than 1 and the population is not in equilibrium. You cannot estimate allele frequency from this information.

CR = 0.7, Cr = 0.3, the genotype ratio is what would be predicted from these frequencies and the population is in equillibrium since the sum of both the frequencies is equal to 1 which is a condition for hardy weinberg equilibrium.
