What do parasitism, predation, and commensalism have in common? How are they different?

Answers

Answer 1

Answer: They are all relationships involving two animals where at least one animal benefits.
Parasitism- Where one organism benefits while the other is harmed. Examples-Mosquitos, ticks
Predation- Where one animal benefits and the other is harmed (or DEAD)
Example- Shark eats seal.
Commensalism- Where one organism benefits while the other is unaffected. Example-Bird riding on cows horns.

The tundra is a cold, ice-covered region on Earth. Recently there has been an increase in the number of plants growing there. This new plant growth is MOST likely due to A) an effort by the local people to plant trees.
B) global warming, resulting in warmer temperatures on Earth.
C) more people going to the area for recreation and vacations.
D) animals leaving the tundra for warmer regions with less snow cover.

Answers

Answer: B) global warming, resulting in warmer temperatures on Earth.

Explanation:

Tundra is the coldest biome of the world. It exhibit very low temperature range and treeless plain with snow precipitation. The global warming is the phenomena which is related with rise in global temperature due to abundance of greenhouse gases into the atmosphere. These gases are released into the atmosphere by burning of fossil fuels, industrial gaseous release and deforestation. These gases traps the heat energy from sunlight making the atmospheric temperature warm. As a result of global warming the ice caps and snow bearing areas of the tundra biome will deplete. The melting of the ice will provide proper unfrozen soil for the growth of plants. Hence, new plants will increase in numbers due to global warming.

The tundra is a cold, ice-covered region on Earth. Recently there has been an increase in the number of plants growing there. This new plant growth isMOST likely due to global warming, resulting in warmer temperatures on Earth.
Thus the answer is letter B.

Which structure is not present in all organisms?A.
a cell wall

B.
a plasma membrane

C.
genetic material

D.
cytoplasm

Answers

A border that exists outside the plasma membrane or cell membrane is the cell wall. It only exists in plant cells and is composed of cellulose. In a cell of an animal, it is absent. Thus, option A is correct.

What is the function of cell wall?

Plant cells have a cell wall that surrounds their plasma membrane and offers tensile strength as well as defense against osmotic and mechanical stress.

Additionally, it enables the development of turgor pressure, or the pressure of the contents of the cell against the cellwall.

Animals lack cell walls, but most other eukaryotes, such as algae, fungus, and plants, as well as most prokaryotes, do (except few bacteria).

Serving as pressure channels, they prevent the cell from over expanding when water enters, which is one of their main roles.

Therefore, cell wall is not present in all organism.

In humans, blood type inheritance is an example ofa. predominance.
b. incomplete dominance.
c. codominance.
d. complete dominance.

Answers

I would say the answer is: Co-dominance

When I was taking biology I learned that there are 3 types of alleles.

You have IA, IB, and little i. The little i means it is a recessive trait. IA and IB are co-dominant. There's a lot more gibberish language I could use.

Good luck and hopefully this helped. If you need me to go into greater detail just let me know.

The researchers sampled all the plots throughout the growing season. They measured growth rates, and they analyzed the chemical composition of living leaves.2.The researchers inferred that something limits grass growth in some places. It could be any environmental factor- temperature, sunlight, water or nutrients. Based on their knowledge of salt marshes, they proposed an idea: Marsh grass growth is limited by available nitrogen.3. Data analysis confirmed that marsh grasses in experimental plots with additional nitrogen grew taller and larger than the controls.4. Researchers observed that marsh grass grows taller in some places than in others. This observation led to a question: Why do marsh grasses grow to different heights in different places?5. The researchers selected similar plots of marsh grass. All plots had similar plant density, soil type, input of fresh water, and height above average tide level. The plots were divided into control and experimental groups.6. The researchers complied all of the data. They compared the average growth rate in each plot and the average height of the plants.
