Answer:
C) Interaction increases the survival and reproductive rates of mutualistic species.
Explanation:
A) Mutualism offer more biodiversity to a community.
Biodiversity is the different species living in one environment. Since mutualism is only involving two species, it wouldn't increase the biodiversity of one ecosystem, making it incorrect.
B) Individuals partaking in a mutualistic relationship relationship are more resistant to parasites.
Mutualism is only benefiting two species, not their immunity to diseases and parasites. These two have no correlation with each other, making it incorrect.
D) Mutualistic interaction lessens competition in communities where it is present.
Since mutualism is only benefiting two species, they have no correlation since the relationship doesn't affect the different species in the environment.
E) Mutualistic relationships allow organisms to synthesize and use energy more efficiently.
Although there could be some relationships involving energy transfer between the species, that would sound more like commensalism or even paratsitism if you think about it. However, it is very uncommon and usually energy has no relationship with species relationships, making it incorrect.
Hope this helps! My deepest apologies if I got in incorrect!
Answer:
1 is a phenotype
2 is a genotype
p reps the given allele of one parent
There would be less oxegen and also economically exploit us as 80% of things we use is from trees. we will be ruined, that's for sure.
<h2><u>
Full Question:</u></h2>
In the family tree below, people with the recessive trait of attached earlobes are shaded gray.
What must be true about the person labeled "A"?
A. It is a male with at least one dominant allele.
B. It is a male with two dominant alleles.
C. It is a female with at least one dominant allele.
D. It is a female with two dominant alleles.
<h2><u>Answer:</u></h2>
Its a male with atleast one dominant allele.
Option A.
<h3><u>Explanation:</u></h3>
The gene for the attached earlobe is recessive while the gene for the free earlobes is dominant. In the phylogenetic tree, we can see that both the father and mother aren't having attached earlobes. So both of them are having atleast one dominant allele which makes them have free earlobe.
In the F1 offsprings, one of the female and a male is having free earlobes. So both of them have atleast one dominant allele. The 2nd female is having an attached earlobe. So both the recessive allele have come form one parent each. So both of them are heterozygous.
Thus, the male marked as A atleast have one dominant allele. He can be a homozygous dominant, but the probability is 25%.
Answer:
pericardium
Explanation:
A double-walled membrane, the pericardium, separates the right and left chambers, preventing oxygen-rich blood from mixing up with the one without oxygen. So, the heart functions go smoothly. Deoxygenated blood enters the right atrium.
