Answer:
The majority of the cell membrane is made from phospholipids and has 2 layers
<span>Due to DNA and Organelle
Duplication that takes place during Interphase within a cell, during the
splitting of a cell in Mitosis, the two daughter cells should have the exact
same genetic and physical composition as the Parent Cell. so the daughter genetic make u p is also AaSs</span>
Answer:
The t-test
Explanation:
<em>The researcher should use a t-test to compare the two means and check if they are significantly different from each other.</em>
In using the t-test, both null (H0) and alternate (H1) hypothesis are made such that:
Thereafter, the value of t is calculated and compared to its critical value on the table. The formula for calculating the t goes thus:
where, Y1 = mean of population 1, Y2 = mean of population 2, S1 = variance of population 1, S2 = variance of population 2, n1 = number of individuals in population 1 and s2 = number of individuals in population 2.
<em>At the end of the day, if the calculated t value is more than the critical value of t, the H0 is rejected and it shows that the two means are significantly different. Otherwise, the H0 is accepted and this shows that there is not significant difference between the mean of population 1 and that of 2.</em>
Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of other animals
Answer:
Three Reasons
Explanation:
1, due to the genome. By birth, there is a biologically higher percentage of body fat in women.
2, unemployment. As normally in a South African household, it is the man that goes out to work while the women stay at home. loss of mobility means the accumulation of fats.
3, Males' major sex hormone is testosterone, and females have high levels of estrogen and progesterone in their blood. Females build up fat more easily than males.
