Answer:
active transport
Explanation:
it involves movement of ions
Answer:
a. Zero percent
b. Fifty percent
Explanation:
As it has been mentioned in the question that both man and woman are normally pigmented and each one have an albino parent thus both will be heterozygous and their allelic makeup will be as follows -
Man - Aa
Woman - Aa
After a cross between Aa × Aa we get the following result-
One AA, Two Aa and One aa
It is clear that only the aa type of offsprings will be albino.
Out of 4 there is probability of only one to be albino so out of two there will be 50% probability of being albino.
The probability of both sons to be albino will be zero percent.
Deforestation is people cutting down whole forests of trees, andmaking it even less likely for humans to survive. Trees supplyoxygen, absorb carbon dioxide, and hold down the soil from washingaway or making landslides. The destruction and cutting down of forests is often done to clearland for farming, mining, roads, and grazing of cattle. That causesincreased atmospheric CO2 levels, a factor in global warming.

In order of importance, the world's four most important crop species are: CORN, WHEAT, RICE AND POTATOES.
Corn is the most produced grain in the world and it is used as raw material for production of different types of food. Wheat is the leading source of vegetable protein in the world, it is usually grown in dry and cold climates.
One of the reasons why the fish population remains approximately the same from one generation to the next is because not all the eggs laid will survive to adulthood. There are several factors which bring about elimination of the the newly hatched eggs. Examples of these are predators and diseases which eliminate the young offsprings at different stages before they develop into adulthood.
Secondly, production of many eggs by the different fish species leads to competition for survival. Resources such as water, food, oxygen and shelter have to be fought for and its only the fittests that will be able to survive till the reproduction stage.
