1. Which feature is found in prokaryotic cells but not in eukaryotic cells?

1 answer:

7 0

The eukaryotic cells do not contain any organelles such a nucleus in particular. The difference in their structures for prokaryotes and eukaryotes will also include the presence of chloroplasts and mitochondria. Also, structures such as cell wall and chromosomal DNA structures are also some of the difference in the two types of cells. The answer to the second question is C.

A bee pollinates flowers social hierarchy social hierarchy territorial imperative territorial imperative competition competition

Ivanshal [37]

Answer:

cooperation

Explanation:

Cooperation occurs when living things of different species work together to benefit themselves. The interaction between a bee and a flower is a symbiotic relationship. A symbiotic relationship between two living things is one in which at least one of the parties benefits. The relationship between the bee and the flower is a mutual one because both parties benefit.

While the pollen and nectar serve as food for the bees, the spread of the pollen to other plants assist in the reproduction process.

Animal and Plant Cell Organelles Use the drop-down menus to determine where these organelles can be found. Ribosome Endoplasmic

rjkz [21]

Answer:

Animal Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, small Vacuoles, Lysosomes, Mitochondria, Cell membrane, Cytoplasm.

Plant Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, Cell wall, Big Vacuole, Lysosomes, Mitochondria, Cell membrane, Cytoplasm, Chloroplasts.

Explanation:

 Animal Cells Vegetable Cells

Cell wall NO YES

Vacuoles YES, Small and more than ones YES, Only one and big

Chloroplast NO YES

Plasmatic membrane YES YES

Mitochondria YES YES

Lysosomes YES YES

Endoplasmic reticulum YES YES

Golgi apparatus YES YES

Cytoplasm YES YES

Ribosome YES YES

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

However, they have some differences:

Cell wall: A rigid structure that provides support and protection.

Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible, so they can adopt different shapes.
Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

Chloroplast: these are organelles that accumulate chlorophyll.

Animal cells do not have chloroplasts because they do not photosynthesize.
Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

Vacuoles:

Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.

Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

Other differences are:

The animal cell has centrioles, while the vegetable cell does not.

Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.

How do scientists determine the toxicity of a chemical

aleksandr82 [10.1K]

Answer:

Toxicity can be measured by the effect the substance has on an organism, a tissue or a cell. We know that individuals will respond differently to the same dose of a substance because of a number of factors including their gender, age and body weight. Therefore a population-level measure of toxicity is often used
