What happens to oxygen that is produced during photosynthesis?
a. It is used by plants to carry out photosynthesis.
b. It is used by all organisms to carry out photosynthesis.
It is used by all organisms to carry out cellular respiration.
d. It is used only by plants to carry out cellular respiration.
C.

Answers

It would be C because oxygen isn’t used by plants and plants only So that would cross out there, B is wrong because humans can’t do photosynthesis. Plants are the only organism that can carry out Cellular respiration, so that takes out D so the only logical answer to say it is used by organisms to carry out cellular respiration
The answer is D because only plants use it all organisms don’t use photosynthesis and oxygen isn’t used in photosynthesis it is given off

meaning of epidemic virus pandemic​

Answers

A pandemic is defined as “an epidemic occurring worldwide, or over a very wide area, crossing international boundaries and usually affecting a large number of people”. The classical definition includes nothing about population immunity, virology or disease severity.

By this definition, pandemics can be said to occur annually in each of the temperate southern and northern hemispheres, given that seasonal epidemics cross international boundaries and affect a large number of people. However, seasonal epidemics are not considered pandemics.

- both a and c
- is an abnormality resulting from a diet high in cholesterol

Answers

Answer:

b) It interferes with the movements of the fatty acid tails of the phospholipids.

Explanation:

Cholesterol has many important functions, including its role in membrane permeability, especially the cell membrane, and its role in metabolism. Cholesterol reduces the permeability of lipid membranes. ... Cholesterol helps to restrict the passage of molecules by increasing the packing of phospholipids. Steroid molecule that makes membranes more fluid at low temps and more ordered at high temps.

- Flat, rigid, carbon rings interfere with the movement of phospholipids.

The best way to practice sustainable use of rangelands is to

Answers

Answer: 1. Rotating the rangelands that are being used.

2. Reducing overgrazing of rangelands.

Explanation:

Rangelands are the sites which are occupied and dominated by vegetation cover mostly the shrubs and herbs. It can be occupied by grasses. Overgrazing by the cattle cause a huge damage to the field of rangeland so  it can cause soil erosion and can convert the rangeland on barren land. The regrowth rate is slower than that of the consumption rate of the cattle. So, reduction in overgrazing is advisable to maintain the sustainability of the land. Rotation of the rangelands being used if the cattle are taken to the different grassland for grazing on alternate days then the rangelands can be maintained sustainably.

Chickens that carry both the alleles for rose comb (R) and pea comb (P) have walnut combs, whereas chickens that lack both of these alleles (that is, rr pp) have single combs. From the information about interactions between these two genes, determine the phenotypes and proportions expected from the following crosses:

a. RR Pp × rr Pp;
b. rr PP × Rr Pp;
c. Rr Pp × Rr pp;
d. Rr pp × rr pp

Based on the context in paragraph 4, fossil refers to ____________.

a. how igneous rocks were formed over time
b. a trace or print, or the remains of a plant or animal of a past age preserved in Earth or rock
c. layers of sediment building up over time and pressing down, forming rock


4. Sedimentary rock is the second category. These rocks cover most of Earth’s land. Sedimentary rocks are made of pieces of other rocks and shells. Erosion causes rocks to slowly wear away. Erosion can be caused by rain, wind, freezing, and plant roots. Sometimes small pieces of rock are made because of erosion. The small pieces of rock are called sediment. Rivers take sediment to oceans and lakes. The river drops the sediments as it slows down. The sediments settle to the bottom in layers. More and more layers of sediment are dropped over millions of years. The weight from the top layers turns the bottom layers of sediments into rock. This makes some sedimentary rocks look layered. Fossils are often found in sedimentary rocks.

Answer:

b. a trace or print, or the remains of a plant or animal of a past age preserved in Earth or rock

Ants provide protection to acacia trees while receiving nutrients from the trees. Mutualism Parasitism Ants reserved PLZ HELP ​

Answers

Answer:

1: Parasitism

2: mutualism

3: parasitism

4: mutualism

Explanation: Hope this helps and have a great day!!

The sentences describe different types of symbiotic relationships between organisms are: Parasitism, Mutualism, Commensalism

1. Parasitism: Sea lampreys hatch eggs on fish and feed on the fish.

In parasitism, one organism benefits (the sea lampreys) at the expense of the other (the fish) by feeding on its tissues.

2. Mutualism: Clownfish help sea anemones catch prey while using the sea anemones for protection.

This sentence describes mutualism, where both clownfish and sea anemones benefit from the relationship. Clownfish protect sea anemones from predators, while they, in turn, provide a safe haven for the clownfish.

3. Parasitism: Mosquitoes suck blood from the bodies of organisms.

Mosquitoes exemplify parasitism as they feed on the blood of other organisms, taking nutrients without providing any benefit in return.

4. Mutualism: Ants provide protection to acacia trees while receiving nutrients from the trees.

This sentence represents mutualism, where ants defend acacia trees from herbivores, and in return, they receive nutrients and shelter from the trees.

5. Commensalism: Ants reserved.

The term "reserved" here seems to be incomplete, but assuming it refers to ants residing in a certain place, it would represent commensalism. Commensalism describes a relationship where one organism benefits, and the other is neither helped nor harmed significantly.

In summary, the sentences describe mutualism, parasitism, and possibly commensalism, showcasing the diverse interactions that can occur in ecological communities.
