Answer:
(08) and (32)
Explanation:
To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.
The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.
Natural selection refers to the phenomenon by which the species in a population possessing the tendency to get adapted in a condition enhance in numbers in comparison to those who exhibit fewer adaptation capacities over a number of generations.
In other words, it can be stated as the non-random and differential development of distinct genotypes function to sustain favorable variant and to eradicate less favorable variants. Some of the conditions are required for the process of natural selection to take place.
These are heredity, reproduction, variation in individual characters, and variation in the fitness of organisms among the members of the population. If the conditions are met, then the phenomenon of natural selection occurs by default.
Answer: 5
Explanation:
Since 1 out of 200 people carry the defective gene that causes inherited colon cancer.
In a sample of 1000 individuals, we say
1 = 200
y = 1000
cross multiply
y x 200 = 1000 x 1
200y = 1000
y = 1000/200
y = 5
Thus, in a sample of 1000 individuals, approximately 5 will be carriers
When the entire group of forces acting on an object is balanced, the vector sum
of the forces is zero, and the effect of the group of forces on the object's motion
is identical to the effect of no force at all. The object continues in constant uniform
motion.
To state the outcome of the situation in three different ways:
-- The object's acceleration is zero.
-- The object's velocity is constant.
-- The object's speed and direction of motion don't change.
The direct answer to the question is: Nothing happens to its motion.
The answer is <span>c. mutualism.
</span>
<span>Mutualism is a relationship between two
different species in which both species have benefits. In this example, ants benefit because they feed on aphids' wastes while aphids benefit because ants provide them protection.
</span>
<span>Commensalism is a relationship between two
species in which only one of them has benefit, and the other one is not
affected. Parasitism is a relationship between two species in which only
one of them has benefit, and the other one is harmed.</span><span>
