Inside the cell is 40% helium and outside the cell is 20% helium. Which of
the following will occur? *
A. helium will move out of the cell
B. helium will move into the cell
C.helium will not move
Answer:
A. Helium will move out of the cell
Inside the cell the concentration is higher than concentration off outer cell so the inner helium well more about of cell
Answer:
\(\boxed {\boxed {\sf A. \ Helium \ will \ move \ out \ of \ the \ cell}}\)
Explanation:
Diffusion is the movement of particles from a high concentration to a low concentration. This is the process occurring in this question.
In this cell, 40% helium is inside the cell.
20% is outside of the cell.
40 is greater than 20. Therefore, the helium wants to move from the area of 40% to 20%, which is also from the inside of the cell to the outside. Basically, the helium moves out of the cell.
So, the best answer is choice A: helium will move out of the cell.

The Galapagos islands have a great diversity of landscapes – from lush vegetation to nearly barren lava fields yet the Galapagos Finches survive on each island.
How can this be explained?
Changes or modifications in body structure helps the Galapagos Finches to survive on both islands.
Galapagos Finches survive on vegetative island as well as island having barren lava fields because of the adaptability of the Galapagos Finches to their environmental conditions. Galapagos Finches adapt the environment where they can live through change in their body structures and feeding behaviours.
The change in their body structure helps Galapagos Finches to survive in that unique environment so we can conclude that changes in body structures helps the Galapagos Finches to survive on both islands.

how does rib cage works in our body for class 5
Answer:
When the lungs inhale, the diaphragm contracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside. As a result, air rushes in and fills the lungs.
Explain why cellular respiration releases energy as an overall chemical reaction
Answer:
In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is to capture this energy in the form of ATP
In other words:
Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

How would this diagram be
different if it showed anaphase I of meiosis instead of anaphase of mitosis?
A Each chromosome would still have two chromatids.
B The chromosomes would look the same as in mitosis.
C You would be able to see DNA in the chromosomes during meiosis.
D Homologous chromosomes would be moving to the same end of the cell
Answer:
This question is incomplete as there is no diagram, however, the question can still be answered without it. the answer is as follows:
A. Each chromosome would still have two chromatids.
Explanation:
The ANAPHASE stage of both mitotic and meiotic division is the stage where chromosomes are pulled apart into opposite poles of the cell. However, meiosis occurs in a two-step division tagged meiosis I and meiosis II.
In mitosis, sister chromatids of a chromosome are separated during anaphase, but in meiosis I, homologous chromosomes are pulled apart during anaphase I. This means that in the anaphase I of meiosis as opposed to anaphase of mitosis, each separated chromosome WOULD STILL HAVE TWO CHROMATIDS.
Which argument provides the MOST LIKELY explanation for why populations of sea stars that use sexual reproduction have increased survival than those populations of sea stars that use asexual reproduction?
a.The population that uses sexual reproduction will reproduce at a slower rate allowing for them to identify and adapt to the new environmental conditions.
b.The population that uses sexual reproduction will have increased genetic diversity which will allow the population to adapt to the changing environmental conditions.
c.The population that uses sexual reproduction will reproduce at a faster rate and replace the individuals that do not survive new environmental conditions.
d.The population that uses sexual reproduction will have less genetic diversity which will allow them to adapt to the new conditions more quickly.
The population that uses sexual reproduction will have increased genetic diversity which will allow the population to adapt to the changing environmental conditions.
What is genetic diversity?Genetic diversity is the term used to describe the amount of variation in a population's genetic material. Genetic diversity is important for the long-term health and survival of a species, as it allows them to adapt to changing environmental conditions. It is also important for the health of a population, as it prevents inbreeding, which can cause genetic defects. Genetic diversity can be measured in a number of ways, including looking at the number of different alleles in a population, the amount of genetic variation in a population, and the amount of variation between individuals within a population. Genetic diversity is influenced by a variety of factors, including mutation, natural selection, and gene flow. Ultimately, genetic diversity is essential for the survival of a species, and it is important to maintain and promote a healthy level of genetic diversity in order to ensure a species’ long-term survival.

Which term describes an organism that remains in one place?
Sessile is the term used to describe an organism that remains in one place.
Why are some organism sessile?
Some animals such as corals and sponges are sessile. These animals don't expend their energy to catch their prey they live by attaching to a substrate. They choose a suitable spot to feed. They can be found on tree trunks, on rocks, and even in water.
Plants are typical example of sessile organism. They permanently grow in one spot taking nutrients from the soil and making use of the available sun for photosynthesis. Sessile organism doesn't have the ability to move from one place to another and it has a big advantage as they save energy and they also develop unique feeding mechanisms enabling them to survive in their habitat.
In summary, sessile organisms don't move yet they feed by attaching themselves to a substrate.
