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.
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.

The pedigree below shows the inheritance of a dominant allele of a gene in a family over several generation. Circles represent females and squares represent males. Shaded symbols indicate individuals carrying the allele. The pedigree suggest that the gene is on a nuclear chromosome, and not on a mitochondrial DNA, because A) mitochondrial genes are not heritable B) mitochondrial mutations cannot produce dominant traits C) maternal mitochondrial mutations are inherited by all of a mother's offspring D) mitochondrial DNA is circular, whereas chromosomal DNA is linear
Complete question:
You will find the pedigree in the attached files
Answer:
The correct option is C) maternal mitochondrial mutations are inherited by all of a mother's offspring.
Explanation:
Mitochondrial inheritance is one of the ways in which a disease or a trait might be inherited from the maternal line.
Most of the DNI is located in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.
In the exposed pedigree, we can see that the mother is affected by the disease, but the couple had two daughters, and only one of them was affected, while the other one was not. This tells us that the mutation occurred on a nuclear chromosome. If the mutated allele was in mitochondria, both daughters would be affected.
The pedigree suggests that the gene is on a nuclear chromosome, and not on a mitochondrial DNA because maternal mitochondrial mutations are inherited by all of a mother's offspring (Option C).
Mitochondrial DNA (mtDNA) is a special type of genetic material that exhibits a matrilineal inheritance pattern.In consequence, all genes (and mutations) contained in mtDNA will pass from the mother to her offspring.It is for that reason that mtDNA is widely used in evolutionary studies (we can trace matrilineal lineage from mtDNA).In conclusion, the pedigree suggests that the gene is on a nuclear chromosome, and not on a mitochondrial DNA because maternal mitochondrial mutations are inherited by all of a mother's offspring (Option C).

Peripheral membrane proteins are found on the outside and inside surfaces of membranes, attached either to integral proteins or to phospholipids. Unlike integral membrane proteins, peripheral membrane proteins do not stick into the hydrophobic core of the membrane, and they tend to be more loosely attached.
11. Many plants use brightly colored flowers to attract insect pollinators.
Which is the MOST likely conclusion about a plant that has very small flowers that
are hard to see?
CLE
Answer: Pollen can be blown in the wind which the bees/other pollinators can follow to get to the flowers.
Explanation: Plants rely on bees and other insects to reproduce and so they have adapted, over time, to become more attractive to them. Bees are drawn to plants with open or flat tubular flowers with lots of pollen and nectar. A flower's scent can have particular appeal to bees, and its bright colors or pollen being blown in the wind may lure the bees in.

Please help and thank you.
Answer:
D / D / D / B / C
Explanation:
I just took the quick check myself, got all of them right :)
1 ) Top predators do not increase the number of prey, neither do they create imbalance or increase the food for other predator species. This is common knowledge, so ruling those out you are left with D. As they do in fact maintain the rest of the food chains populations.
2) A top predator in the ocean is a shark. Of course some might mistake a small whale to be a top predator, but sharks are actually known to hunt whales- the small ones anyway. A sea lion fish or a bird wouldn't exactly be a candidate for the top of the food chain either.
3) During seasonal flooding, to an area such as a river, water gets added to the existing pool, and many biotics and abiotics take this to their advantage. As a result- biodiversity actually increases during these times, but once season flooding is over it goes back to being the same.
4) The impact difference of seasonal flooding from damming a river is actually quite big. Seasonal flooding is.. well.. seasonal.. while damming for the most part is permanent, or will be there for much longer time span than season flooding is. Seasonal flooding increases biodiversity, but damming does not. This is becuase of the long term increase of water, the environment has to readapt, as plants that were once there drowned, and the known species most likely ran off to find better environment. Here it takes a while but eventually new abiotic and biotic species adapt and reclaim the dammed area of the environment.
5) Yes, a long term increase in the average temperature would disturb the ecosystem. Even if it's for a little bit, it's still something the environment wouldn't be used to, meaning the plants and animals there would have to learn to adapt for the time being- even if its temporary.
1: It maintains other populations
2: A shark
3: The biodiversity of the area increases
4: Seasonal flooding does not impact biodiversity for as long term as damming.
5: Yes, because such a change could have a large-scale impact on wildlife.

Column 2 is labeled Step 4: Test for Diffusion Starch with entries Clear initial color and Black after 15 minutes, Yellow initial color and Yellow after 15 minutes. Column 3 is labeled step 7: Test for Diffusion of Glucose with entries Not observed, Light Blue initial color and Red after 15 minutes.
Analysis:
diffused though the semipermeable membrane.
Answer:
only glucose
Explanation:
The second student set up solutions that were in equilibrium.
On which principle Dialysis is based?Dialysis is based on the principles of osmosis, meaning the net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration. If the solute concentrations are the same on each side of the membrane, this spontaneous movement will not occur.
In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Therefore, the second student set up solutions that were in equilibrium.

What impact on plants due to depletion of nitrates or nitrogen?Nitrate plays very vital role in our ecosystem and such that due to presence of the nitrogen plants grow rapidly as well as it produces bigger size fruits and flowers. Plants absorb nitrates in water through their roots without nitrates, the amount of the chlorophyll in leaves reduces.
Nitrate has been a common inorganic ion found in plants that has required for proper growth and development. Many growers has been included the addition of the nitrates in their nutrient regiment to the stimulate plant growth. Plants has been acquire nitrate through the root intake from the soil and water around them.
