Cells reproduce by splitting in half, a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller?
Answers
Answer:
Grow
Explanation:
Before every cell division, cells replicate their DNA to pass on to the daughter cells. They also grow in size and replicate their organelles to ensure that each daughter cell has sufficient resources to carry out all the activities necessary for its function. They also ensure there are sufficient nutrients to perform their tasts.
Cells only need to grow in size and contents before each cell division so as to avoid getting smaller in size with successive divisions.
Each of the daughter cells produced during mitotic cell division goes through an interphase period. The interphase period is divided into 3:
G1 phase: a period characterized by cell growth. An increase in size and volume of content is achieved in this stage.S phase: a period characterized by the synthesis of DNA. The amount of genetic materials (DNA) doubles up in this stage, whereas, the chromosome number remains constant.G2 phase: a phase in which protein is synthesized. After this stage, the cell is ready to pass through a period of division.Without going through the stages above, a cell will simply go into a dormant phase which is essentially a resting phase.

explain what natural selection is and how it occurs
Answers
Answer:
Natural selection is when an animal adapts to their environment to survive and produces more offspring. It occurs when the animal isn’t thriving in their environment and they make adaptions to where they can survive.
Explanation:
An example of natural selection is, a bird used to have a really thick and short beak. But to have more access to food they adapted to their environment and now have a long and skinny beak.

Answers
Answer:
Released as heat
Explanation:
The vast majority of energy in the ecosystem is used by the organisms to power chemical reactions in the cell.
Therefore, this energy is lost as heat when it powers metabolic processes, rather than being passed on to the next trophic level.

Which is denser, 50 mL of water or 500 mL of water?
Answers
Answer:
50mL
Explanation:
Density is inversely proportional to volume.
This implies that, for the same mass of water, the higher the volume, the less dense it is.
By comparison 500ml is greater than 50ml
Going by the above analysis, 50ml will be less dense than 500ml because it is smaller.

Answers
Answer:
Photosynthesis is when plants convert sunlight, water, and oxygen into energy.
photosynthesis is how plants grow
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere and supplies most of the energy necessary for life on Earth.

4-This period of 223 synodic months is called a saros.
5-Each year there are between 2 and 5 solar eclipses.
6-The total solar eclipse, when the Moon completely obscures the Sun and leaves only the faint solar corona, is known as a Totality.
7-Total solar eclipses are rare, happening only once every 18 months.

how does coriolis effect affect the climate zones in the world? PLEASE HELP! I WILL GIVE BRAINLY TO PROPER ANSWER!
Answers
Answer:
Please Mark as Brainliest
Explanation:
The development of weather patterns, such as cyclones and trade winds, are examples of the impact of the Coriolis effect. ... As warm air rises near the Equator, for instance, it flows toward the poles. In the Northern Hemisphere, these warm air currents are deflected to the right (east) as they move northward.
There is only one structure that explains the full vortex structure of storms. That structure is an Electromagnetic particle vortex. Sorry folks the Coriolis effect is one of those things that needs sent to the dustbin of history (Trash for Americans).
The weather plasma flow linkages are being well studied now. There is no reason to continue to teach Coriolis Effect regards rotation of storms. It does have effect in things like the massive ocean currents and the generalized flows on earth of winds but it doesn’t affect rotation of storms. Even there we are learning that motion north and south from the equator is primarily electrical in nature.

Natural Selection is survival of the fittest aka Darwinism. It basically states that the strongest survive and the weakest don't. Maybe it's through food shortages, bad weather, or predators. It occurs in an organism for population control. If there is too big of a population, then there will be a recourse drought and natural selection will do its thing again.
