Answer:
Air pressure is influenced by the differences between hotter and cooler pockets of air, or fronts.
Explanation:
When atmospheric pressure is low, air is pushed down toward the surface, meaning rain and moisture don't accumulate. This often also leads to high humidity near the surface of the Earth, where people experience weather.
Lunar phases are basically the different positions of the moon that we see throughout its whole cycle, from new moon to full moon, back to new moon. Eclipses, though are more rare phenomena. These occur when the sun, moon, and earth line up at a specific position.
Asteroids are usually dense bodies, with many different formations on their surface. They are also believed to be the largest source of precious metals on our planet.
Comets are bright clouds of gas surrounding a center nucleus that speed toward the sun and heat up at the same time. They contain dust, ice, carbon dioxide, and other gases. As the comet soars toward the sun, the radiation pushes dust particles back, forming the tail they are known for.

Explanation:
Genotype- Is the genetic makeup of an organism.
An homozygous individual is one who has similar allele e.g AA
It could either be in dominant form(AA) or recessive form(aa)
An heterozygote individual has two different allele in its genotype e.g Aa
A dominant gene is a gene that expresses itself in the phenotype of an individual while a recessive gene is a gene that is not expressed in the phenotype.
The genotype for a white homozygous flower is WW while the genotype for homozygous recessive is ww.
The dominant genotype is usually denoted with capital letter and the recessive is denoted with small letter.
Answer:
Scientists believe that fitness is not only the ability to have physical fitness but it also refers to the adaptations that make an organism survive in its environment.
According to biological studies, biologists believe that the ability of an organism to survive in a particular area and to pass on its characteristics to its offspring is fitness.
The health scientists define fitness as the ability of an individual to be physically fit and to move without pain.
The scientists which study psychology believe that fitness is the well functioning of a person;s body as well as his/her mind.
