Answer:
Option B, He has a homozygous genotype
Explanation:
A dominant allele is one which will overshadow the expression of recessive allele. Thus, when a dominant allele and recessive allele appears together in the genotype of offspring , only the trait associated with the dominant allele is expressed. Therefore , if a recessive allele trait is to be expressed , the offspring must have both the recessive allele
Let us see case here
A. Allele for attached earlobes is recessive (e)
B. Allele for detached earlobes is dominant (E)
If offspring has EE genotype, then he/she would have detached earlobes
If offspring has Ee genotype, then also he/she would have detached earlobes as in heterogyzous genotype traits of dominant alleles are expressed.
If offspring has ee genotype, then only he/she would have attached earlobes
Genotype ee is a homozygous recessive genotype
Answer:
You can predict the growth rate by using this simple equation: growth rate = birth rate – death rate. If the birth rate is larger than the death rate, then the population grows. If the death rate is larger than the birth rate, what will happen to the population? The population size will decrease.
Explanation:
I don't have an explanation
For sure, one of the answers is Plate tectonics. The second answer would most likely be subduction, due to the fact, in the lessons revolving this question, it mentions both earthquakes and volcanoes caused by subduction.
B. is a long crack, which releases lava, steam, and gases
Explanation:
A fissure is a long crack which releases lava, steam and gases into the environment. Fissures are mostly associated with volcanic bodies.
A volcano is an igneous structure by which lava erupts on the earth surface.
- most volcanoes have fissures through which they release materials into the environment.
- these features are usually permeating cracks into the deeper magmatic body.
- they often times acts as conduit for magma to reach the surface.
- in a volcanic terrain, fissures can provide good clues to the occurrence of an eruption.
