Answer:

Chemical reactions involve the rearrangement of electrons and Isotopes of the same element behave differently in a nuclear reaction.

The regulation of protein synthesis is NOT strict as in eukaryotes. It is due to the lack of cell nuclei.

Prokaryotes are simple unicellular organisms that lack cell nuclei and membrane-bound organelles.

Conversely, eukaryotic cells contain a cell nucleus where the process of transcription (DNA >> RNA) takes place.

The absence of compartmentalization of the genetic material makes the process of transcription simpler in prokaryotes than eukaryotes.

Answer:

ultraviolet waves are utilized by insects to locate nectar.

Explanation:

When prokaryotes live as interacting communities in which one population benefits to the harm of the other, the type of symbiosis is called Parasitism.

At the level of species, the ocean is much less diverse than the terrestrial environment, with only approximately fifteen (15) percent of the total known species.

Biodiversity makes reference to all forms of life and different populations we can identify in a given ecosystem.

Biodiversity is a fundamental issue for the maintenance and equilibrium of the whole ecosystem.

The loss of biodiversity may lead to the extinction of one species and even to the irreversible change of the ecosystem.

Answer: The present atmospheric CO2 increase is caused by anthro- pogenic emissions of CO2. About three-quarters of these emissions are due to fossil fuel burning.

56 pages

Explanation:

The increase in burning fossil fuels has most likely caused the recent increase in atmospheric CO2 levels. Therefore, option (C) is correct.

The carbon cycle is the process by which carbon moves between the atmosphere, land, and ocean. Carbon is continuously exchanged between the atmosphere, plants, animals, soil, and the ocean through various processes, such as photosynthesis, respiration, and decomposition

When fossil fuels such as coal, oil, and gas are burned, they release carbon dioxide into the atmosphere that had been locked up in the Earth's crust for millions of years. This addition of carbon dioxide to the atmosphere is not balanced by natural processes such as photosynthesis, which removes carbon dioxide, and respiration and decomposition, which release it. As a result, the concentration of CO2 in the atmosphere has been steadily rising, contributing to global climate change.

The low-intertidal zone

Explanation:

The low intertidal zone has the most organisms considering it has the most favorable conditions, since it isn't subject to tides uncovering this area.

Answer:   The correct answer is the low intertidal zone since it is only exposed during low tide and has the greatest biodiversity of the three zones because it provides more favorable conditions for those organisms that cannot tolerate air exposure for longer amounts of time.

Answer:

Birds don’t get electrocuted when they land on power lines because the lines are grounded to distant devices, and the current never passes through the birds, because their electrical potential is greater than the ground. If the grounding is removed, then the birds will die.

The reason why The water gets wet Is due to the existence of two forces:"forces of cohesion"which are the forces that have attached to the water particles (H2O) and the"forces of adhesion"are those that are manifested when the water molecules come into contact With another surface.

Explanation:

Answer: They're Not Good Conductors. Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird's presence and continues to travel through the wire instead of through the bird's body. A bird's body is not a good conductor of electricity.

Wetness is our description of what we feel when we put our hand in water. Saying water is wet is like saying that wood is hard or fire is hot. Sensory receptors on our hand send information about the water to our brain. But my theory is Water is dry. The reason is becuase, if water touches water, it doesnt get more wet, so its dry.

Answer: she built a immunity from getting the disease

Explanation:

Answer:  In gymnosperms, the gametophyte generation takes place in a cone, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule.

Hope this helps!

Answer:

The male cones release pollen into the air. The wind then carries the pollen to the female cones. The pollen gets stuck in a sticky liquid produced by the ovule. Sperm from the pollen fertilize the egg in the ovule. The ovule then develops into a seed. When the seed is mature, it is dispersed. If conditions are good, the seed grows into a seedling, which grows into a tree. The tree produces cones, and the cycle begins again.
