Science About Osmosis And Diffusion

Answers

Answer 1
If a living cell was placed in a sugar solution, it would cause outward osmosis to occur. The solution outside the cell would be hypotonic (containing fewer solute molecules than inside the cell). Water will move into the cell by inward osmosis and the cell would then swell.
Answer 2
a. 1. Cell membrane pulled away from the cell wall.
2. Vacuole shrined and became smaller

How can you decrease the effort force needed to push a weight to the top of the ramp? A) cover the surface with carpet B) increase the length of the ramp C) increase the height of the ramp D) decrease the length of the ramp

Answers

Answer:

B) increase the length of the ramp

Explanation:

Less force is needed to move the object over a longer distance.

Answer:

You can decrease the effort force needed to push a weight up the ramp if you increase the length of the ramp. You could also decrease the height of the ramp.Lengthen the ramp, decrease the mass of the object, use a machine  can you decrease the effort force needed to push a weight

Explanation:

A ramp is an example of an inclined plane. Think back to the example of the ramp and the moving truck. The ramp reduced the amount of force needed to lift the box by moving it over a greater distance. The longer an inclined plane, the less force is required to move an object upward.

A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.

What do you mean by Hardy-Weinberg equilibrium?

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

This was simulation. What are some variables that this peppered moths simulation does not address?

Answers

Answer:

The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.

B) Community - a group of one species living in a given area

C) Population - the regions on Earth that can support life

D) Ecosystem - all of the living and nonliving factors in an environment

E) Biosphere - anything that meets all of the characteristics of life

Answers

The correctly paired ecological level with its description is the option D. Ecosystem - all of the living and nonliving factors in an environment, among given options.

An ecosystem is a geographic region or area where all the living factors including animals, plants, bacteria, and others interact with all the physical or non-living factors such as landscape, humidity, water, and many more.

Other given ecological level and their description:

Organism - an organism is the living being that is the simplest form of ecological level composed of organ systems.Community - It is a population with similar characteristics that live in a particular area.Population -  a group of members of a particular species living and interbreeding within a given area.Organisms > Population > community > ecosystem

Which of these is true of fetal development by the end of the third trimester?
A. The placenta is absorbed by the uterus.

B. The fetus can survive outside the uterus.

c. All development is complete.

D. All growth is complete.

Answers

Answer:

B. The fetus can survive outside the uterus.

Explanation:

The third trimester starts in the wekk 28 (month 7 ) of fetal development and lasts until the birth pf baby, that is around week 40 (month 9) of pregnancy.

There are several changes occur in the thrid trimester of the fetal development such as hearing and visual has developed and the internal organs  including the heart, lungs, intestines and stomach has developed enough.

During the third trimester, the fetus continues to grow in weight and size however the body systems finish maturing. In fact, both mother’s  body and the fetus continue to grow and change. Lungs, brain and kidneys keep maturing. Fetus position itself head-down and is 6 to 9 pounds in weight. Skull bones are soft but fetus become able to suck its thumb and cry.

The excretory system may be defined as the system that consists of a pair of kidneys, ureters, and urinary bladder. It removes wastes from the body.

Excreting waste materials, maintaining pH balance, maintaining body temperature, maintaining salt balance, maintaining hormone levels (aldosterone), and maintaining water balance are all the functions that are performed by the excretory system.

Therefore, only excreting blood is the function that is not performed by the excretory system.
