Answer:
Option D
Explanation:
Options for the question
A) The Y chromosome is slower to mature than the X chromosome.
B) Replication of the X chromosome occurs more often in males.
C) Male hormones cause the expression of X-linked traits.
D) Males only have one copy of the X chromosome
Given-
Duchenne muscular dystrophy (DMD) is an X-linked recessive condition which means it will occur in male even if they have one diseased X gene. While females will have this disease only when they have two diseased X gene
Hence, in most of the cases women with only one diseased X chromosome act as carrier and show normal traits.
Let us assume X is normal gene and X' is the diseased gene then
Genotype of normal father will be - XY
Genotype of carrier mother will be - XX'
Now if these two mates, following offspring will be produced
XY * XX'
XX, XX', XY, X'Y
So the male with X'Y will have DMD
Hence, option D is correct

Drought and leaching leave some parts of Africa without much water, which leads to some portions of the area to turn into a desert, which can prove disastrous for the plants and animals that now find themselves in a completely different habitat.
Answer:
there are three types of memory: sensory memory, short-term memory, and long-term memory. ... But, our minds also possess sensory and short-term memory. Not all memories are the same; the different types function in different ways.Long-term memory is usually divided into two types—explicit and implicit. ... Explicit memory can be further divided into episodic memory (specific events) and semantic memory (knowledge about the world).Photographic memory is a term often used to describe a person who seems able to recall visual information in great detail. Just as a photograph freezes a moment in time, the implication for people thought to have photographic memory is that they can take mental snapshots and then recall these snapshots without error.Scientists are still unsure about this question. Researchers say that animals, non-humans, do not have a true language like humans. However they do communicate with each other through sounds and gestures. ... But they slowly learn the words of the language and use this as form of communication.
