In the study of cancer, researchers have used different types of cells, different environmental conditions, and different
experimental designs. But, all researchers have arrived at the same conclusion. What does this say about the
conclusion?

Answers

Answer: In study of cancer, researchers have used different types of cells, different environmental conditions, and different experimental designs. But, all researchers have arrived at the same conclusion that the study is well supported to cancer studies.

Mr. Chavez wants his class to prepare a procedure that would demonstrate cellular diffusion. Which of the following procedures would best demonstrate cellular osmosis?

A. A procedure that uses the skins of potato left overnight in oil

B. A procedure that uses a cluster of grapes left overnight in a high concentration of salt water
C. A procedure that uses a 2-liter bottle filled with oil and water and left overnight

D.A procedure that uses a banana that has been left overnight in milk

Answers

Answer:

B

Explanation:

The second option correctly shows the process of cellular osmosis.

When the grapes would be immersed in water, the molecules of water move across the cell membrane from the region of low to high solute concentration. Due to this, the water would leave the cells and diffusion of water from the cells of the grapes. Thus, option B is the correct answer.

In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).

Osmosis refers to the movement of a solution (often water) across a selectively permeable membrane.

This movement (osmosis) is due to the difference in solute concentrations on both sides of the semipermeable membrane.

In osmosis, water molecules move from a region of low concentration of solutes (e.g., salt) to a region of high concentration of solutes.

In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).

Answer is A, Homologous Structures

Explanation:

The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants are classified as Homologous structures. Option A is correct.

Homologous structures:

These are the structures in the different organisms that show similarities in the basic organization of the structure.

These organisms are from common ancestors, Homologous structures serve completely different functions.For example- The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants.

Analogous structures are those structures that serve the same function but are from different ancestors.

Which type of energy change causes this leaf to grow? A. Thermal energy is transformed into potential energy. B. Thermal energy is transferred to the leaf. C. Electromagnetic energy is transformed into chemical energy. D. Electromagnetic energy is transferred to the leaf.

Answers

Answer:

C. Electromagnetic energy is transformed into chemical energy

Explanation:

Growth is one of the characteristics of living things. It refers to the increase of an organism. A leaf is part of a plant, which is a photosynthetic organism i.e. an organism capable of producing its own food using energy from sunlight. Light energy is a part of the ELECTROMAGNETIC ENERGY.

This light energy is used to synthesize glucose (food) via photosynthesis. The glucose, which stores chemical energy in its bond is then broken down to yield ATP used for growth. Hence, the transformation of electromagnetic energy to light energy is how a leaf grow.

it is C.  Electromagnetic energy is transformed into chemical energy.

where is sugar removed and how can you tell​

Answers

Explanation:

What you need to understand first, is the digestive system, after that, you'll probably be able to understand not only sugar, but other components of your food too.

    It all starts at your mouth, you are going to do a lot of the job for the food to get to your stomach by chewing it. After it gets to your stomach, the digestion will do its job as the pH there is less than 7. After this process, the food is going to your intestine, and then, it's right here, that the sugar/carbohydrates you ate are going to get into your blood. After this, sugar is going to be used to create energy for your cells and body to work properly, with that, sugar is consumed and you can start the process all over again.

Mrs. Gupta is the Cub Scout den mother. She is taking a troop of boys on a camp out and believes it will be easier if she schedules the outing to happen during the full moon. Last night she observed a third quarter moon. Approximately how many days will she have to wait before the full moon? 7 14 21 28

Answers

Answer:

The correct option is 21

Explanation:

First of all, it should be noted that the full moon is usually observed in the middle of the lunar month, which is usually 29 or 30 days, hence the full moon can be observed either on the 13th but most likely on the 14th and/or the 15th of the lunar month.

At the early days of the month, the new moon begins to form a crescent which appears and continues to get fuller (called waxing crescent) as the day goes by until half of the moon is noticed (usually after about seven days) on one side, this is known as the first quarter.

After half of the moon is noticed on one side, the moon continues to get fuller (called gibbous moon) until a full moon is noticed on the 14th/15th day. This full moon then starts waning or becoming smaller until the other half of the moon becomes visible while the initially seen half becomes invisible/clouded (this is called third quarter). This happens after another 7 days or on the 21st day. This half moon continues to get smaller (forming a waning crescent) until no moon is seen at the end of the month (around the 28 or 29th day) which is referred to the new moon.

Hence, we can see from the above that from the third quarter to a new full moon will go through the steps below

third quarter ⇒ new moon ⇒ first quarter ⇒ full moon

If each step takes about 7 days and there are 3 steps, the approximate number of days she has to wait before the full moon is 21 days.
