Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis.
Answer:
The correct answer is - option B) humidity.
Explanation:
Independent variable is the variable in a scientific experiment that can be modify or change in order to find out the response and analyse the response of dependent variable.
In this experiment the independent variable is humidity as it is changed in order to find out and study plant growth response by the effect of humidity.
Thus, the correct answer is - option B) humidity.
If the mother is a carrier and the father is normal, the outcomes for potential children would be:
XH Xh
XH XHXH XHXh
Y XHY XhY
So let’s break these down
XHXH = will be a daughter (XX) with normal blood (HH)
XHXh = will be a daughter (XX) who is a carrier for hemophilia (Hh)
XHY = will be a son (XY) with normal blood (H)
XhY = will be a son (XY) with hemophilia (h)
Because this disease is inherited on the X chromosome, male offspring tend to either have it or not. They can’t be carriers because they only have one X chromosome. So the chances of having a son with hemophilia will be 50% cause the boys have a 50% chance of inheriting hemophilia.
On the other hand, daughters will either have normal blood or be carriers in this situation. So to answer the question, the chance a daughter of this couple would have of inheriting hemophilia is 0%. This only changes if their father has hemophilia. Then they will either be a carrier or will have hemophilia.
