Is the cell an open or closed system? Explain your

Biology
1 answer:
ahrayia [7]3 years ago

·         In an open system matter and energy can be transferred

·         In a closed system only energy can be exchanged

·         In an isolated system neither matter nor energy can be exchanged

·         The cell has to be an open system because it needs to exchange matter and energy and the only way to do so is through an open system

·         As an open system the cell allows nutrients to enter the cell and waste products to exit the cell

·         The cell does this through the use of a semi-permeable membrane

·         It needs nutrients in the forms of glucose, ions and many other molecules.

·         The nutrients can come into the cell through either passive or active transport

·         In passive transport the nutrients naturally move from a higher concentration gradient to a concentration gradient.

·         During active transport the particle need to move against the concentration gradient. To do this the cell needs energy to transport the materials. The energy comes in the form of ATP.

Genetic disorders can result in chroma tides fail to separate properly during which phase is this problem most likely to our car
Alex Ar [27]

Answer:

Anaphase of meiosis II

Explanation:

I think you are asking during which phase of cell division sister chromatids are mostly likely to fail to separate properly, a phenomenon that can lead to genetic disease.

This is sometimes called non-disjunction, and it is most likely to occur in anaphase during meiosis II. During this stage, sister chromatids of the two daughter cells produced by meiosis 1 are separated and brought to opposite parts of the cell. If something goes wrong at this stage, the sister chromatids can fail to separate properly, meaning the daughter cells do not have the correct number of chromosomes (see attachment).

An example of such a genetic disorder is Down syndrome

Why dont chickens fly?
Lena [83]
Chickens are capable of flight, however their domestication doesn't require it of them. After hundreds of years of being cultivated by humans, chickens have evolved to be less competent at flying than other birds. Chickens are ground feeders, which means they eat grubs and small plants. Since they do not need to hunt down prey like a hawk, they also do not need the wing strength to fly like one. Chickens are able to fly enough to access trees when they need to escape from predators.

BRAINLIEST FIR RIGHT ANSWERS, WHAT SHAPE AND WHY?
Tatiana [17]

Answer:

Explanation:

Hydrogen cyanide (HCN)

The molecular geometry of HCN is linear. The compound is polar in nature.

As Carbon is bonded to two atoms, it follows the molecular geometry of AX2. And as per VSEPR theory, molecules covered under AX2 have a linear molecular geometry.

Hence Hydrogen Cyanide has linear molecular geometry.
