Answer:
The skeletal muscle fibres are of two types namely slow-twitch muscle fibres (type I muscle fibre) and fast-twitch muscle fibre (type II muscle fibre).
The slow fibres are slow contracting and help in developing endurance such as long distance running, maintaining posture etc whereas fast fibres are fast contracting and help in movements which require force such as sprinting etc.
Other differences are summarized in a tabular form attached below.
Answer:
The one who determines the gender of a new baby is the father, since he is the carrier of the X and Y sex chromosomes.
Explanation:
The sex chromosomes X and Y are called sex determinants, since the sex of the offspring depends on them:
- <em>XX</em><em> corresponds to the female sex.
</em>
- <em>XY</em><em> corresponds to the male sex.
</em>
A mother can only provide her offspring with X chromosomes, while the father can provide both X and Y chromosomes, so he is the one who determines the sex of a new child. In this case, the possibility of having a male or female child will always be 50:50
