1. A. What is diffusion?

1. B. Use diffusion to
explain what happens when you drop a
sugar cube into a mug of hot tea.

2. A. What is osmosis?

2. B. Describe how water molecules
move through the cell membrane during
osmosis.


Answers

Answer:

Diffusion is the spreading of something more widely. When you drop a sugar cube in hot tea the sugar cube spreads out and the sugar starts to dissolve in the tea. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. If the concentration of water molecules ouside the cell is lower than the concentration of water molecules outside the cell then the water moves out through osmosis. Water travels through the cell membrane.

Diffusion is the movement of particles from a higher concentrated area to a lower concentrated area
Omosis is the movement of solvent particles across a sermipermeable membrane from a dilute solution into a concentrated solution

As water passes into the guard cells, the pore opens. explain why.

Answers

Answer:One of the most important functions of guard cells is to control the closing and opening of the stoma/pores. While the opening of these pores allows water to be released into the environment, it also allows carbon dioxide to enter the cell for photosynthesis (as well as the release of oxygen into the environment).

Explanation:

Answer: guard cells are a pair of cells that surround each of the stoma openings. to open the cells, they have to be triggered by one of many possible environmental or chemical signals. these can include more sunlight or higher than normal levels of carbon dioxide within the cell.

Explanation:

they open to regulate the gas and moisture exchange, hope that this is what you were looking for :)

In what ways did Charles Lyell impact Charles Darwin’s theory of evolution? What type of relationship did Darwin have with Charles Lyell? How did Darwin learn about Charles Lyell's ideas?

Answers

Answer:

They both believed that continuous and gradual change is law of nature

Explanation:

Charles Lyell's “Principles of Geology “ encouraged Charles Darwin to think of evolution of living organisms as a slow process just like the slow geological processes taking place since millions of years. As per Charles, the slow and little contribution of continuous geological events shaped the present geological attributes of the earth. Likewise Charles Darwin’s theory of evolution also earmarked accumulated effects of small gradual changes over immense spans of time. They both believed that continuous and gradual change is law of nature.

Which of the following is always true of two organisms in
the same taxonomic class?

A.They can breed with one another

B.They have certain physical features in common

C.they evolved at the same time

D.they live in the same ecosystem​

Answers

Answer:

they can breed with one another, they have certain physical features in common, they evolved at the same rate, they live in the same ecosystem. Lions and house cats share common features, but cannot breed with one another.

Explanation:

They share a common ecology, they may breed with one another, share some physical characteristics, evolve at the same rate, and inhabit the same ecosystem, hence option D is correct.

What are the taxonomic classes?

If two species are members of the same class, they are also members of the same higher-level taxon. They share the same phylum and kingdom in this instance.

Kingdom, phylum or division, class, order, family, genus, and species are the seven main taxonomic ranks.

The taxon with the greatest number of species is the kingdom. In taxonomy, it is the broadest category into which the creatures can be divided.

The classification of five kingdoms was made by R.H. Whittaker. The kingdoms of Monera, Protista, Fungi, Plantae, and Animalia are included in this classification.

Therefore, option D is correct.

Explain why the forest ecosystem is a system.

Answers

A forest ecosystem is a natural woodland unit consisting of all plants, animals and micro-organisms (Biotic components) in that area functioning together with all of the non-living physical (abiotic) factors of the environment. The forest ecosystem is very important.

Answer:

Like all ecosystems, forests consist of many interacting parts. They include living organisms such as plants, animals, and fungi. Forests also include non-living components that these organisms depend on, such as the soil and climate. As stated in the article, one change, such as pollution, can cause a ripple effect through the ecosystem. Dying lichens are one of the earliest signs of pollution. In turn, the loss of the lichens can cause a decline in species that rely on the lichens for survival.

What is the purpose of the ATP and NADPH produced in the light reactions of photosynthesis?
A. to transfer light energy to excited electrons
B. to stop the electron transport chain
C. to act as carrier proteins in inner mitochondrial membranes
D. to transfer energy to compounds forming three carbon sugars

Answers

Answer: D. to transfer energy to compounds forming three-carbon sugars

Explanation: ATP and NADPH are produced in the light reactions by
when energy absorbed from the sun is conserved as ATP and NADPH. ATP and NADPH generated in the light reactions of photosynthesis are used to synthesize carbohydrates from carbon dioxide and water. The ATP and NADPH are used to reduce CO2 to triose phosphate which can be used to produce glucose. Green plants contain unique enzymatic machinery in their Chloroplasts which catalyzes the conversion of carbon dioxide to simple organic compounds in a process known as CO2 assimilation or carbon fixation. In this carbon fixation reactions, ATP and NADPH is used to drive the incorporation of carbon dioxide into ribulose 1,5-bisphosphate to produce glyceraldehyde 3-phosphate (a 3-carbon sugar) in a series of enzyme catalyzed reactions.

During mitosis, the original cell produces two daughter cells. How many daughter cells will be produced if 250 mouse cells undergo mitosis?

Answers

Answer:

There would be 500 daughter cells if 200 mouse cells went through the process of mitosis. (If that's what your asking)

Explanation:

During mitosis, the organism (which would be an asexual producer) doubles the amount of chromosomes and they divides the doubled number by two. So the organism will always end up with two daughter cells with the same number of chromosomes as itself. (That is the way with asexual producer's-their offspring is always an exact replica of the first). Now, if you take one mouse, it would end up with 2 daughter cells. If 250 mice reproduce, each with two daughter cells, then there would be 500 daughter cells in total, because you would multiply 2 by 250.  

The number of daughter cells that will be produced is;  500 daughter cells

Mitosis is a process of cell replacement or cell growth whereby a cell divides into two exact daughter cells containing the same number of chromosomes each as the number of chromosomes contained in the parent cell.

Given that the original cell produces two daughter cells, when 250 mouse cell undergoes this process we will have

250 * 2 = 500 daughter cells.

Hence we can conclude that the number of daughter cells that will be produced is 500 daughter cells
