Answer:
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement.

Answer:
Honestly nothing much unless you consider them to keep populations low of over populated animals.
Explanation:
Strong legs and huge front claws are used for digging, and long, sticky tongues for extracting ants and termites from their tunnels. In addition to bugs, armadillos eat small vertebrates, plants, and some fruit, as well as the occassional carrion meal. Armadillos are the only mammals that have protective armor. The mammals are known to dig up insect larvae for food, and it's possible they will compete for such meals with resident animals such as skunks. Armadillos have also been known to raid the nests of various species and so could harm populations of ground-nesting birds such as quail.
Answer:
A)
Explanation:
b and e kills organisms, so it doesn't evolve the diseases. genetic modification causes the plants to be resistant, and doesnt target diseases, so the disease isnt evolved. only antibiotics make diseases evolve, overuse of it causes the disease to develop resistance if it isnt completely killed off.
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
