Several are correct:
Affect males more than females
Can be carried by females
Are always expressed by males
A bit of explanation: sex linked genes are carried on the X chromosome. That’s why it affects males more than females...they only get one x from their mom. Females can be affected IF they receive 2 bad X chromosomes. So with a male, the bad gene on the x is always expressed. Color blindness is a good example of this.
Answer:
The correct option is : b. centrosome
Explanation:
Centrosome is a cell organelle, which acts as the microbule organizing center and also regulates the cell cycle progression in an eukaryotic cell.
During the prophase stage of the cell cycle, the centrosomes are associated with the membrane of the nucleus. The nuclear membrane ruptures during the mitosis and the interaction of the centrosome nucleated microtubules with the chromosomes leads to the formation of the mitotic spindle.
<u>Therefore, mitotic spindles arise from the centrosome.</u>
Answer:
From CARBONDIOXIDE (CO2) found in the atmosphere
Explanation:
Photosynthesis is a process performed by autotrophic organisms like green plants. It is a phenomenon whereby these plants manufacture their own food (sugars) using an inorganic carbon source in the presence of sunlight to provide energy.
The major end product of photosynthesis is glucose, which has a carbon constituent i.e. C6H12O6. However, this carbon needed to make glucose is got from an inorganic molecule called CARBON DIOXIDE, which the plants take from the atmosphere in via the stomata on their leaves.
Answer:
The answer is double helix.
Explanation:
In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases. Watson and Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix.
Hope this helps!! ;)
