Diferencia entre las bacterias y los virus.
myrzilka [38]

Answer:

Los virus son más pequeños y no son células. A diferencia de las bacterias, necesitan un huésped como un humano o un animal para multiplicarse.

Las bacterias son organismos vivos unicelulares. Tienen una pared celular y todos los componentes necesarios para sobrevivir y reproducirse. Los virus no se consideran "vivos" porque requieren una célula huésped para sobrevivir a largo plazo, para obtener energía y para reproducirse.

Explain why it is impossible for a man to be a carrier of a sex-linked trait.
hoa [83]

Answer:

Because it contains two different sex chromosomes

Explanation:

Man in its genome contains two sex chromosomes, X and Y, while woman contains two X chromosomes.

In order to be a carrier of a sex-linked trait, a person should have one copy (one allele) of a certain trait. For example, if a female has one X chromosome with mutation (e.g. disease carrying) and one normal X chromosome, she is carrier for the disease. But, on the other hand if a male has one X chromosome with mutation he will develop that disease.

How does global warming lead to climate change?
Aleonysh [2.5K]

Answer:

global warming leads to climate change as global warming is caused by carbon dioxide trapped in the earth's atmosphere. sunlight can get trapped in the atmosphere as there is a high concentration of CO 2 so the sunlight hits the CO 2 and it bounces back to earth and because the CO 2 is covering the atmospehere it will keep on reflecting and that heats up the air causing water to evaporate and the climate to change
