Answers
Answer:
Dissolved or gaseous substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen. Diffusion occurs when particles spread.
Explanation:
To enter or exit a cell, dissolved or gaseous substances must pass through the cell membrane. One of the mechanisms that makes this possible is diffusion. Particles diffuse when they spread.
What is cell?Cell is defined as the fundamental membrane-bound entity that houses the essential molecules of life and is the building block of all living things.
It can also be defined as a semipermeable cell membrane encloses one or more nuclei, cytoplasm, and different organelles, which are the smallest structural component of an organism capable of autonomous functioning.
There are basically two types of cell.
Prokaryotic cellEukaryotic cellCell membrane is defined as a biological membrane that keeps all cells' interiors isolated from the outer world and provides protection for it.\
Barriers and gatekeepers are cell membranes. Because of their semi-permeability, some molecules can diffuse across the lipid bilayer but not others.
Thus, to enter or exit a cell, dissolved or gaseous substances must pass through the cell membrane. One of the mechanisms that makes this possible is diffusion. Particles diffuse when they spread.

The table below shows the percentages of bases in a DNA sample. How much Guanine (G) should you expect to find in the sample?
Answers
Answer:
17%
Explanation:
guanine is cooped
with cytosine
Using Chargaff's rule, the percentage of Guanine(G) in the sample is always equal to the percentage of Cytosine. Hence, the percentage of Guanine which is expected to be found in the sample ls 17%.
From the table attached :
Thymine = 33%Cytosine = 17%According to Chargaff ; the percentage of Cytosine equals the percentage of Guanine :
Guanine = Cytosine = 17%.
Percentage of Thymine equals the percentage of Adenine :
Adenine = Thymine = 33%Therefore, the amount of Guanine which is expected to be found in the sample is 17%

1. What is the function of a top predator in an ecosystem?
A. It increases the food for other predator species.
B. It creates imbalance in the ecosystem.
C. It maintains populations. **
D. It helps increase the number of prey.
Reason - The answer is C because predators couldn't possibly increase the food for other predators. They obviously don't imbalance the ecosystem since they help keep it cycling. And they can't increase the number of prey if they're eating prey so therfore you're left with C.
2. Which is considered a top predator in the ocean?
A. A shark**
B. A sea lion
C. A small whale
D. A bird.
Reason - The answer is A because actually the top predator in the ocean is the killer whale but since it's not an option, you'd wanna go for a shark. A small whale obviously couldn't eat a big shark, nor could any of the others. :)
3. What happens to an ecosystem during normal seasonal flooding?
A. The biodiversity of the area reaches equilibrium.
B. The biodiversity of the area increases. **
C. The biodiversity of the area decreases.
D. The biodiversity of the area stays the same.
Reason - Just trust, I'm trying to finish this post and got tired of giving reasons. Sorry and thanks:)
4. How is the impact of seasonal flooding different from damming a river?
A. Seasonal flooding helps balance biodiversity, but damming does not.
B. Seasonal flooding is not considered an ecological disturbance like damming.
C. Seasonal flooding does not impact biodiversity for as long term as damming.**
D. Seasonal flooding increases biodiversity, but damming does not.
Reason - Again, trying to finish this and tired of typing reasons but the answer is indeed C because damming a river can causes long-term damage to biodiversity and the ecosystem while it can quickly recover from a flood because it doesn't really damage as much and the flood will simply be gone after a bit. :)
5. Would a long-term increase in the average temperature of a region be considered a significant disturbance in the ecosystem?
A. No, because it would not create large-scale changes in the environment.
B. No, because increases and decreases in average temperatures are normal.
C. Yes, because such a change could have a large-scale impact on wildlife. **
D. Yes, because any slight change in temperature is considered a distribution.
Reason - Eh.. it's pretty self explanatory.
Answers
It maintains the population. The top predator of the ocean is a shark, biodiversity of the area increases, the seasonal flooding may impact biodiversity for as long term as damming. Yes, due to the change could have a large-scale impact on wildlife.
What are the Exkplanion for the above answers?As per the top predators of the ecosystem, thy duty is to maintain the level of populating in the community. As they hunt down prey and thus be balanced. The ocean is just like the land is full of predators and prey the shark is the largest top predators species in the oceans.
A dammed river can create long-term damage to the biodiversity of the region. As flooding can lead to disaster and may impact the food supply. A long-term increase in the temperature of the region can lead to a large impact on wildlife.
