In pinus species male cone matured earlier than female cone because it male cone producing more pollen grain.
Explanation:
Pinus species don't have flowers who has nectar and pollen. Pine trees can’t attract bees and butterflies for pollination. Wind play vital role for pollination in pinus species tree.
The male cones produce producing pollen grains, which drift to the female cones on other trees. After few years mature the non-fertilized female pine cone mature to become the woody cones
The extra X chromosome is received from mother.
<h3><u>Explanation</u>:</h3>
Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.
Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind.
I would believe C because the water isn’t disappearing the plants/mud are taking up space.
