I disagree with this statement. Asexual organisms are at a lower risk for extinction due to the fact that they do not need a partner to procreate. They have an easier time making offspring.
Answer:
I think it is B. medium tell me if I am wrong
Answer:
Because the offspring of a male and female are always going to be xx, xx, xy, or xy.
Explanation:
Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.
So we can write the this out in a punnet square as(link down below).
After you see the visual, you will find that the genotypes are xx, xx, xy, xy.
As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.
So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.
Answer:
In biomes the species community undergoes certain changes in evolution and growth in order to reach the climax.
Explanation:
- An alternative stable state is one which suggests the discrete states are sperate by an ecological threshold and in opposition to the ecosystem that is changing and thereby stating that the ecosystem can exist in a variety of alternative state.
- The first species after origin grows develops and then declines. This community of species may be disturbed in middle such as by a fire or flood and forms the secondary community which is more diamine and resistant. The changes are known as seres in biomes.
Ezywhen salinity in soil increases the soil becomes hypertonic when compared to cell sap.the movement of particles from a lower concentrated solution to a higher concentrated solution is callede osmosis. in general conditions cell sap is at higher conc. than surrounding media. this allows water and minerals to enter the plant. but when soil is at higher conc. i.e., when its salinity increases the process becomes reversed can you imagine its consequenses?
