Answer:
Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope. Eukaryotes belong to the domain Eukaryota or Eukarya; their name comes from the Greek εὖ and κάρυον. The domain Eukaryota makes up one of the domains of life in the three-domain system; the two other domains are Bacteria and Archaea. Eukaryotes represent a tiny minority of the number of living organisms; however, due to their generally much larger size, their collective worldwide biomass is estimated to be about equal to that of prokaryotes. Eukaryotes evolved approximately 1.6–2.1 billion years ago, during the Proterozoic eon.
Explanation:
Answer:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

What is the use of tail in human sperm?
It’s an adaptation that allows the sperm to travel to the egg more efficiently as the distance is long and most sperm do not make it to the egg so this increases the chance of fertilisation.

what is carrying capacity? what type of population growth does it affect?
Carrying capacity is referred to a population size of species in a particular habitat. In an ecosystem, the population of a species will increase till it reaches its carrying capacity. Then the population size remains relatively equal.
What are the types of carrying capacity?Carrying capacity is the maximum limit till that the ecosystem can support the existence of the population.
There are four categories of carrying capacity, namely:
Physical.Ecological.Economic.Social.A specific environment's carrying capacity is the maximum population size that it can support.
The carrying capacity modifies the growth rate by slowing it when resources become scarce and stopping growth once it is reached.
Thus, it can be concluded that the carrying capacity is the average population size of species in a particular habitat which slows and stops the growth rate on reaching it.

explain how the energy producing processes occurring in the cells of organisms drives the cycling of matter within an ecosystem
Answer:
The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon based organic molecules and release oxygen

how might toxicology be important to other biomedical professions outside of forensics?
Answer: See explanation
Explanation:
Toxicology is a field in science that has to do with the effects of poisons, toxics and how they can be treated. Through toxicology, one can understand how harms are caused by chemicals and the health of the public can be protected.
Toxicologists study chemicals, drugs and other substances, and looks at how safe they're and their impact on living organisms. Toxicologists help in the development of methods that'll be used to know the harmful effects and the the dosages which causes it.
Furthermore, toxicology gives vital information and knowledge which the decision makers or regulatory agencies
in other biomedical fields can use in order to put programs in place that can be used to limit the exposures of humans to the substances.
In conclusion, less exposure to these substances is vital so that diseases can be prevented.
Toxicology is also used in the field of environmental health.
Toxicology will be important to other biomedical professions outside of forensics. Toxicology can be used in environmental health field which provides critical information and knowledge about the toxic substances that can be used by regulatory agencies to limit our exposures to toxic substances so we can say that toxicology plays an important role for other biomedical professions.

The surface of rivers freeze when the temperatures falls below freezing. However, the water underneath this layer of ice continues to flow. This phenomenon allows fishermen to fish through holes drilled in the ice the entire winter. Which property of water is the reason the river doesn't freeze completely?
Answer: Water retains its temperature for long.
Explanation:
The ice floats on the water of river as it is less denser then the liquid water. This causes ice to float on water. It protects the water at the bottom from freezing. The decrease in the temperature level can cause the death of the marine life by catching organisms in the ice. The floating of the ice insulates the water present beneath. So, the fish and other aquatic animals can survive and the fishermen can catch the fishes alive.
