I have no idea what that means but the answer is b
Answer:
Combined parenting leads to faster reproduction
Explanation:
Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.
During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.
Fertilization permits parental genes to be brought together. This causes variations in members of the same family.
Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
The keystone species is the one at the bottom of the pyramid, if we look at it like a pyramid. If the grass dies, then the deer cannot get food and die, and the predator cannot eat and dies, and the whole ecosystem can fall apart.
Answer:
Due to the dense atmosphere
The magnetic field of the earth
Explanation:
Most particles in the solar wind do not reach the earth's surface because the atmosphere is very dense and the protecting magnetic field of the earth.
A solar wind is a burst of energetic particles from the sun which are made up electrons, ions, etc.. They travel at a very high velocity.
- The magnetic field of the earth is able to deflect these charged particles away.
- In areas such as the pole, the interact with the atmosphere to produce very stunning auroras.
Answer:
d is zero (0)
Explanation:
ψ(x)=ce^κx+de^−κx
Let say x = - 1000
We have something like
ce^κ* -1000 = approximately zero
Where we assume k to be 1
C becomes zero as it tend to negative infinity
But
If k is 1
de^−1* 1000 =d * 2 * 10^434
To have a zero function d = 0
So 0 * 2 * 10^434 = 0
