Mutations are changes that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.

They increase the genetic variation within a species because they can create entirely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis which reshuffles alleles within an organism's offspring.

victus00 [196]
<span>Waves in a given area typically have a range of heights. For weather reporting and for scientific analysis of wind wave statistics, their characteristic height over a period of time is usually expressed as significant wave height. This figure represents an average height of the highest one-third of the waves in a given time period (usually chosen somewhere in the range from 20 minutes to twelve hours), or in a specific wave or storm system.

Explanation:

Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.

Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.

Answer:

The 2 ways abiotic factors affect biotic factors are as follows:

  1. An alligator submerges itself under water to stay cool in the summer.
  2. A naked mole rat creates burrows underground.

Explanation:

Abiotic Factors:

All non-living factors that is present or influences an ecosystem. Abiotic factors determine the dynamics of an ecosystem such as the terrain, the atmosphere as well as the inhabitant flora and fauna. Water, sunlight, oxygen, temperature, and soil are all abiotic factors.

Biotic Factors:

All living factors in an ecosystem i.e. the plants and animals.

Lets analyze all the options:

  • A bird picking food out of an alligator's teeth is an interaction between 2 biotic factors, the bird and the alligator or in another case, the bird and the food.
  • Water being oxygenated is an interaction between 2 abiotic factors: water and oxygen.

10 pounds of walnuts cost $50. How much does 1 pound of walnuts cost?
valentina_108 [34]

Answer:

$5 is the cost of 1 pound of walnuts

P (Pounds) = 5D (Dollars)

Explanation:

Since 10 pounds of walnuts = $50.

Let 1 pound of walnuts = Z

then, cross multiply

So, Z = ($50 X 1 pound) / 10 pounds

Z = 50/10

Z = $5

Thus, 1 pound of walnuts will cost 5 Dollars while P (Pounds) = 5D (Dollars) is the equation that shows the relationship between pounds and dollars
