Answer:
The answer is A
Explanation:
Plants use photosynthesis to create oxygen and glucose from carbon dioxide in the chloroplast and animals get some of this energy by eating the plants (look up Energy Pyramid for more examples)

A cell has a 1% salt concentration. It is placed into a solution containing a 10% salt concentration.
What will happen to the cell?
Choose 1 answer:
Water will move out of the cell, causing it to swell.
Water will move into the cell, causing it to shrink.
Water will move into the cell, causing it to swell.
Water will move out of the cell, causing it to shrink.
Answer:
Water will move out of the cell, causing it to shrink.
Explanation:
When something with a low salt concentration is placed in a higher concentration of salt, the salt in the solution will try to suck out the water in the cell. Just remember why we hate salt, because it sucks! There's a little joke to help u remember. Thanks, Ms. Hoj :)
Answer:
CORRECT (SELECTED)
Water will move out of the cell, causing it to shrink.
Explanation:
The cell has lower concentration of solute and a higher concentration of water than the solution it is placed in. This means that water will move out of the cell, causing it to shrink.

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
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.

As water passes into the guard cells, the pore opens. explain why.
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 :)
What part of the respiratory tract is considered the respiratory zone?
A. Bronchioles
B. Larynx
C. Trachea
D. Alveoli
Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
Answer:
Yep, the correct answer is D.) Alveoli

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.
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.

write a paragraph to show your knowledge about diabetes that include the following terms:
Glucose, Glucagon, Pancreas, Negative Feedback, Homeostasis, and Liver
Answer:
Glucose is a simple sugar molecule that helps play a role in high/low blood sugar levels. If your blood level is too low Glucagon is released to increase your blood sugar and if it’s too high Insulin is secreted to lower blood sugar; both Insulin and Glucagon are hormones.This being said these two hormones are secreted by the pancreas. Both of these two hormones are examples of negative feedback leading to a stability In homeostasis. It is regulated by the liver, however if homeostasis is disrupted the body will stop functioning properly leaving no insulin to be produced. Therefore the end result is Diabetes

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

What is currently happening with Mount Etna?
Answer:
As Italy’s National Institute of Geophysics and Volcanology (INGV) explains on a recent blog post, the nascent eruption began on the night of May 29. Starting off by producing a thick column of ash rising from the New Southeast Crater, it gave way on May 30 to a far more lava-heavy display in the area, featuring two fissures blenching out lava.
Answer:
There is currently no eruptive activity at the volcano involving fresh lava and monitoring signals do not suggest an immediate change likely; only a weak thermal anomaly continues to be present from the southeast crater complex.

Explain why the forest ecosystem is a system.
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.
