Answer:
A single gene on the Y chromosome plays a crucial role in the parental development of the testes.
Explanation:
Y chromosome is present only in males and this chromosomes is the distinguishing factor which separates males from females. It is the smallest chromosome but of utmost importance due to its sex determining feature. Up till now, studies show that Y chromosomes only carry limited amount of genes.
The Y chromosome, most importantly, comprises of the SRY gene. This is the gene responsible for determining the testis and for the development of the testis. The SRY gene is responsible for sex determination.
Answer: c. The myosin would not be able to let go of the actin
Explanation:
Muscles consists of two proteins called actin and myosin and responsible for muscle contraction.
Myosin is ATP dependant and when ATP binds to it, it is able to release the actin.
This will allow the actin and myosin to seperate from each other thus leading to muscle contraction
Answer:
independent variable: the different amount of water
Explanation:
The independent variable would be the <u>different amount of water supplied to the pea plant clones.</u>
<em>The independent variable is the variable inputted by the researcher during an experiment whose value directly affects the dependent variable. It is the variable that is manipulated during experiments in order to see the kind of effects they produce on another variable - the dependent variable.</em>
In this case, <u>the amount of water supplied to each pea plant would directly affect the height of the pea plants.</u> Hence, the amount of water supplied to the pea plants is the independent variable while the height of the plants is the dependent variable.
