Answer:
It;s c (Granite)because "a coarse-grained, felsic igneous rock is not only a granite, it is an intrusive igneous rock that formed from slow cooling and crystallization of a body of magma within the earth's crust. ": )
Explanation:
Answer:
D. The scientist uses tennis balls to show the position of the planets and Sun.
Explanation:
In a layman's terms, the solar system is a system consisting of the sun and the planets that orbits around it. These planets are as follows; Mercury, Mars, Earth, Saturn, Venus, Jupiter, Neptune, Uranus etc.
According to this question, using a physical model to represent or describe the solar system means the use of physical objects that can easily be seen or identified. Based on this explanation, the use of tennis balls to show the position of the planets and Sun suits the physical model description of our solar system.
<span> COMPLETE DOMINANCE:
</span>
<span>Mendel concluded that some alleles are dominant and others are recessive. When one dominant allele is present, it's enough to make the recessive allele unexpressed (this is what happens in heterozygous individuals). In other words, it 'hides' or masks the recessive allele.
CO-DOMINANCE:
-a condition in which both alleles are dominant.
</span>
There are alleles that have the capacity of dominating at the same time, and when an organism is heterozygotic, both alleles are expressed.
For example, a white chicken(WW) crossed with a black chicken (BB): 100% of the offspring being WB. With this genotype, they have black feathers and white feathers.
It's not a blend of colors, but a case where both are expressing.
INCOMPLETE DOMINANCE:
-a condition with none of the alleles is dominant or recessive, so the traits blend in the phenotype.
Some alleles are not completely dominant, and when that's the case the phenotype of a heterozygous organism will be a mix between the phenotypes of its homozygous parents.
For example:
plant 1: RR -red
plant 2: rr- white
By crossing this plants we will obtain 100% of the offspring with a color mix: pink.(genotype: Rr)
Red and white are not completely dominating so it results in a blend of colors.
SEX LINKED TRAITS
Sex chromosomes contain genes that determine the sex of a person. Two X chromosomes result in a female and one X plus a Y result in a male.
In those chromosomes, there are genes specific for each gender, and in those chromosomes, there are genes that code for certain traits- the sex-linked traits.
These traits will be inherited according to the sex chromosomes they receive from their parents.
As population and density and competition increase, the death rate goes along with the positive curve so death rate increases.
