Why was mendels work not accepted at time?

1.) Coal, Oil, Solar and Natural Gas are considered to be sources of energy while POWER is not considered among the rest this is because it's energy in action and not a source of energy.

Coal, oil and natural gas are known as fossil fuels which are the most common sources of energy in industries and homes. These fossil fuels are destroyed by use, that is, they cannot be recovered. Alternative sources of energy is the solar which is gotten from the sun energy. Although not considered a very efficient energy producer, there are already discovered schemes that would provide us with an inexhaustible supply of energy which would also not cause any pollution problems.

2.) Biodegradable, Recycling and Sustainability are means by which pollution is being avoided in the environment. While DEFORESTATION is a process that can cause pollution of an environment, therefore it doesn't fit into the rest of other words.

Biodegradable materials can be broken down by microorganism. Examples include human and animal excreta. Recycling is the reprocessing of waste materials in order to be re-used. This reduces the amount of waste that are sent to incinerators. While sustainability is the maintenance of the ecosystem to remain diverse and productive over time. This could be seen in the preferred use of renewable energy over non renewable energy. But deforestation is the massive cutting down of trees which can cause soil erosion and climate changes leading to the pollution of the environment.

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.
