Answer:
All of the F1 progeny would be wild-type.
If the two mutations are in different genes, then we expect complementation to occur (each mutant strain provides a functional copy of the gene that is defective in the other strain) and wild-type progeny to be produced
Answer:
The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes (endosymbiosis) is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.
Explanation:
Both mitochondria and chloroplasts are similar to bacteria in size, and like bacteria, they reproduce by dividing in two.
For an experiment performed in the laboratory to be effective, a controlled environment is essential.
A laboratory will help to increase the reliability of hypothesis testing, as there will be less interference from the external environment in the experiment.
The design of the laboratory must then be aligned with the needs of the experiment, providing materials and an environment necessary for carrying out the experiment and learning.
<h3 /><h3>What is a scientific experiment?</h3>
Corresponds to a scientific methodology used to test hypotheses on a topic, through the manipulation and control of variables to prove or disprove an assumption.
Therefore, a scientific experiment carried out in the laboratory will help to reduce bias and interference, generating greater reliability in the results found.

#SPJ1
Answer:
No, it is not possible
Explanation:
Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.
This system is such that;
Type A can only have genotype: iAiA or iAi
Type B can only have genotype: iBiB or iBi
Type AB can only have genotype: iAiB
Type O can only have genotype: ii
According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).
Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)
Answer:
Probably B
Explanation:
They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct. Sorry I couldn't be more helpful, I'm only here because I searched for the answer myself. Good luck.
