Answer: c
Explanation:
Grazing is a method of feeding in which herbivores, such as sheep, feed on plants. The intensity in which the herbivores in an ecosystem graze impacts the biodiversity of the plants in that ecosystem, as shown in the graph below.
According to the graph, biodiversity is low during low grazing intensities. This is because only a few species of plants are able to outcompete the others and dominate the ecosystem. As the grazing intensity increases, the biodiversity increases because the dominant plant species are kept in check by the grazers. This allows the weaker competitors to grow. At very high grazing intensities the biodiversity decreases because only plants with adaptations to tolerate the effects of grazing are able to survive.
Which of the following best explains how plant biodiversity would change if all of the grazers were suddenly removed from an ecosystem experiencing high intensity grazing?
A.
Plant biodiversity would likely decrease because every species of plant could grow without limitation after the herbivores were removed.
B.
Plant biodiversity would likely increase because removing one population from an ecosystem would allow more resources for all the others.
C.
Plant biodiversity would likely decrease because a few of the more dominant plant species would outcompete all the others.
D.
Plant biodiversity would likely increase because only a few of the remaining plant species would be able to thrive without the herbivores.
Answer:
I believe the answer is B , it should be .
Explanation:
Answer:
Plant biodiversity would likely decrease because a few of the more dominant plant species would outcompete all the others.

DNA is responsible for making a cell¨s what?
Answer:
The answer is in the explanation bellow
Explanation:
the major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA.
The lymphatic system serves which purpose?
Answer:
One of the lymphatic system's primary jobs is to collect excess fluid (particularly lymph fluid) surrounding the body's tissues and organs and return it to the bloodstream.
Explanation:
If the lymphatic system didn't drain excess fluid from the tissues, the lymph fluid would build up in the body and cause swelling. hope this helps!

Explanation:
Describe the amount of sunlight at the poled and at the equator throughout various times of the year. Why does this occur?
Answer:
Neither of the poles are tilted towards the sun. Hence, the sun rays fall directly on the equator due to which all the places on the Earth experience equal daylight hours and equal night time hours that is, 12 hours of day and 12 hours of night on all the places of the Earth.
Answer:
The fact that the equatorial Sun is always so close to the zenith at solar noon explains why the tropical zone contains the warmest regions on the planet overall. Additionally, the Equator sees the shortest sunrise or sunset because the Sun's path across the sky is so nearly perpendicular to the horizon.

Why does asexual reproduction result in offspring with identical genetic variation? Use the examples that you studied earlier in this lesson to support your answer.
Answer:
The reason asexual reproduction results in identical offspring is because the DNA is replicated exactly from the parent to the daughter. One example is bacteria.
Explanation:
Answer:
Sexual reproduction results in offspring with genetic variation due to the multiplication brings about limitless prospects of hereditary variety. The examples, that can be studied to support this would be at the end of the day, sexual generation brings about posterity that are hereditarily extraordinary. They vary from the two guardians and furthermore from one another. This happens for various reasons.

Where is the mRNA made?
Answer: mRNA is made in the nucleus
Explanation:
how would you describe what the cells of each stage of the cycle look like ? what are the visible features of the cells.
Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.

Organisms combine glucose and oxygen in order to release energy in what process?
What are three tasks that DNA must be able to perform in all organisms? Select three answer choices.
A. It must store genetic information.
B. It must discard foreign genes.
C. It must instruct cells to produce needed molecules.
D. It must copy itself.
E. It must move to locations throughout the cell.
Answer:
A. It must store genetic information.
C. It must instruct cells to produce needed molecules.
D. It must copy itself.
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is the genetic material found in virtually all living organisms. It is the biological molecule that holds the genetic instructions needed for the synthesis of useful products (proteins).
DNA molecule must be able to perform the following tasks in a living organism to be considered the genetic material:
- It must store genetic information: DNA is the storage molecule for genetic information in living cells.
- It must instruct cells to produce needed molecules: DNA must be able to undergo gene expression where it directs the synthesis of the needed molecules like proteins, which it encodes.
- It must copy itself: DNA must be capable of replication i.e. must be able to produce two identical copies of itself.
Answer:
A. It must store genetic information.
C. It must instruct cells to produce needed molecules.
D. It must copy itself.

Why do you think that living and non living things depend on each other in order to survive?
Explanation:
You depend on each other and need the nonliving things in your home, like food, water, air, and furniture. Living things need nonliving things to survive. ... They are food for many animals. Plants use water from the soil, carbon dioxide from the air, and energy from sunlight to make their own food.
Answer:
Organisms depend on other organisms and on the nonliving things in an ecosystem to meet their basic needs for food, water and protection. ... Plants use energy from the sun to produce their own food from air and water. The type of soil, amount of water and temperature range in an area determine the plants that grow there.

Explain how similar and different sexual reproduction in plants and animals is?
Plant's reproduce via. pollen or seeds, whilst the animals reproduce by, and I quote, "getting on top of each other to have a fun time". Hope that helped
Answer:
Both plants and animals reproduce sexually, producing a male and female gamete, which fuse to form a zygote. However, plants are also able to reproduce asexually, unlike most animals. In sexual reproduction in animals, the two gametes are the spermatozoa and the oocyte, which when fused become the ovum.

Explanation:
Mineral ions are required in the human diet in small quantities. State the mineral ion required for each process: a) making bone b) making haemoglobin
Answer:
a) making bone - Calcium
b) making hemoglobin - Iron
Explanation:
Mineral ions are defined as the charged forms of minerals which are required in small amount in human body but are essential otherwise leads to deficiency symptoms.
Making bone and making hemoglobin both require mineral ion. Making bone require calcium ion, as it maintain the bone mass and strengthen the bones. hemoglobin formation require iron ion, as iron helps to oxygenate our blood cells.
Hence, the correct answer is "a) making bone - Calcium
b) making hemoglobin - Iron".
