A plant dies if it’s pholem tissue removed why

Answers

Question:-

A plant dies if it’s pholem tissue is removed. Why?

Answer:-

When the phloem is removed, no substance is transported, the plant does not have the necessary requirements to carry out the process (photosynthesis), and finally the plant dies.

Phloem is composed of various special cells called companion cells, phloem fibers, and phloem parenchyma cells.
Phloem helps the plant by carrying sugar,amino acids and other nutrients from roots to the leaves,stem and other parts of the plant. If the phloem is removed then the transportation of substances won't take place and plants would not get the needed requirements to carry out its process and at last the plant dies.

Plants can synthesize energy rich in sugar molecules using photosynthesis and later break it down into energy for performing life processes using cellular respiration. These two processes require direct interaction between what organelles?

endocytosis

Explanation:

Endocytosis is defined as the process of trapping a particle or even a substance from the external environment by the process of engulfing it. The flexibility of the cell membrane helps the cell to engulf the food and also other materials from the external environment. Such a process is called endocytosis whereas exocytosis is the fusion of secretory vesicles with the plasma membrane and results in the discharge of vesicle content into the extracellular space

Help please and are the ones that already answered to are correct ?

Answers

Yes, all of your answers are correct except for number 12. Instead I would say a food chain outlines who eats whom but a food web is all of the food chains in an ecosystem.

Primary consumers are basically herbivores, such as squirrels, rabbits, crickets, etc.

Secondary consumers are carnivores/omnivores, animals that eat other animals such as foxes, snakes, and owls.

Higher order consumers are animals that can eat more things, like humans for example, because we eat animals that are bigger than us like cows but we also eat plants.

Omnivores are animals that eat meat and plants, such as humans and mice because according to your food web, mice also eat meat.

I can’t see the picture very well because it’s blurry, but i think the owl eats some kind of animal that looks like a frog and snakes, so if the owl is removed the frog animal thing and snakes would increase.

for the last question, i would say

In an ecosystem, a deer consumes grass. What percentage of energy will the deer acquire from the grass? 0. 1% 1% 10% 100%.

Answers

In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.

The percentage of energy transferred to the deer after feeding on the grass is 10%.

The 10% law of the energy states that:

1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.

2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.

Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.

The correct answer is Option C.

Explanation:

Publishing can play a major factor in how a scientist is regarded. This is because the number of publications scientists produce can affect who gets a raise, who gets hired, who gets fired, and who gets funding to do more experiments. Consequently, a phenomenon is known as “salami-slicing” has arisen in science. Instead of publishing a large comprehensive study containing all the results as one large paper, scientists often slice up the work into the smallest units possible and publish these as several separate papers—often in different journals.

Research the phenomenon of scientific salami slicing, and list at least two possible ethical problems that can arise from this practice.
Explain how this practice can affect the way that scientific information is disseminated to nonscientists.
Create a suggestion for a policy that scientists or science journals could follow that would reduce the amount of salami-slicing that occurs in research. Suggest any problems that the policy might cause.

Answers

Salami slicing is the procedure of dividing one single article research into several publications. It is an unethical practice because hampers the healthy competence between scientists for research (job) positions.

In the phenomenon referred to as 'salami slicing', a group of similar research articles published by the same research group are considered 'slices' of the same salami.

This practice can affect not only the work of scientists but also journalists who might report the same results once and again.

A possible solution for this problem is to create a Review Board consisting of experts capable of identifying salami slice articles and then punish the responsible parties.
