"Gravitational attraction" is initially responsible for the formation of the clumps of matter within this interstellar cloud.
<u>Answer:</u> Option C
<u>Explanation:</u>
About 4.6 billion years ago, the solar systems were a bunch of gases and dusts, referred to solar nebula. Gravity squeezed the material as it started to rotate, creating the sun at the middle of the fog.
The rest of the material began to accumulate with the sunrise. The smaller particles moved together to form larger particles that were connected by gravity. As lumps develop, gravity increases and turns into kinetic energy of moving particles that collide and produce heat.
A function of the cell structure that it provides support to labeled x .
What is the function of cell?
- They give the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks.
- Additionally, cells have the ability to replicate themselves and contain the body's genetic material.
- Each component of a cell has a different purpose.
What is cell structure and function?
- Cell architecture - Individual parts of the cell structure each have a specific purpose that is necessary to carry out life's processes.
- Cell wall, cell membrane, cytoplasm, nucleus, and cell organelles are some of these elements.
- Continue reading to learn more about the composition and operation of cells.
3 Major Functions of a Cell -
- Energy Generation.- Living cells exist in a perpetually active biological state. .
- Molecular Transport - Each cell is surrounded by a membrane that delineates its boundaries and acts as a gatekeeper, controlling the movement of molecules into and out of the cell.
- Reproduction.

The correct answer is answer choice b.
Fertilization is the impregnation, the state when<span> a sperm cell penetrates the egg cell and the genetic material of both cells combines.
A few days after fertilization i</span><span>mplantation happens. Implantation is the attachment of the fertilized egg to the uterus, happens on average about 9 days after ovulation/fertilization (between 6 and 12 days) and is required for the fetus to continue to grow.</span>
To survive natural selection, one must be fit and be able to adapt to the environment and situations, thus why it's called survival of the fittest.
