Answer: 1. homozygous
2. phenotype
3. linked
4. dominance
5. (a) brown, (b) brown, (c) green, (d) brown, (e) blue
6. The law of segregation states that each organism obtains one allele for a given gene from each parent in the reproductive process.
7. Mendel conducted hybridization studies looking at how cross-breeding of pea plants led to offspring with various characteristics. He wanted to understand how traits were passed from parent plants to their offspring.
Explanation: answers for PF students
Well you should know about a punnet square, so anyways you have the result of the punnet square, if you have a dominant allele then the phenotype would be that allele, while the genotype is the dominant and either a recessive allele or a dominant allele.
Answer:
B is the correct option because, in a cell, <u>only mitochondria</u> generate and provide <u>energy</u> for muscle movement.
Explanation:
Mitochondria are known as a powerhouse of the cell because they perform <u>cellular respiration</u> and <u>generate energy as an ATP</u> (Adenosine Triphosphate) molecule. <u>Muscle cells function in movement and burn more energy that's why they have many mitochondria to fulfill energy demands.</u>
On the other hand, options <u>A, C, and D are not correct options </u>because mitochondria do not perform other services such as acting as protein factories, linker cells, nutrients transportation. The activities are performed by other organelles.
Answer:
The chemical reaction is sped up.
The activation energy is lowered.
Explanation:
When enzymes are added to a chemical reaction, they lower the activation energy needed in the reaction.
In return, that also speeds up the chemical reaction, since less energy is needed to start it.
Enzymes do not stop chemical reactions, and enzymes can also be reused, so they are not used up.
So, the first and third statements are correct.
