Answer:
Community, also called biological community, in biology, an interacting group of various species in a common location. For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
Explanation:
How could one determine if two
unidentified organisms share a common
ancestor?
Answer:
Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.
Explanation:
DNA
They can look at the DNA it's the most common one.
There are 4 pieces of evolution and they are
Fossils , Geography , Embryos / DNA , Anatomy
Fossils: Physical remains of species , Determine age, location, environment
Deeper layers = older
Geography: Proves species share common ancestors, depending on where
they live
DNA: BEST evidence because it’s the MOST ACCURATE
Similarities in the early stages of development
Similarities in DNA
More similarities = closely related
More differences = not related
Anatomy: Compare body parts of different species to see how they evolved
3 different structures:
Homologous (same structure, different function)
Analogous (similar structure, different organisms)
Vestigial (body parts that no longer serve a purpose)
All of that are in evolution

A coolie of 40 kg weight carries 20 kg salt and climbs up 20 steps of 20
centimeters each in 2 minutes. Calculate the work done by him and his power.
[g= 10 m/s2)
ma
OW
Explanation:
Given
mass of coolie = 40 kg
Mass of salt = 20 kg
Total mass (m) = 40 + 20 = 60 kg
Displacement (h) = 20*20 = 400 CM = 4 m
Work done (w) = ?
Power (P) = ?
We know we have the formula
work done =force × displacement
or work done = m * g * h
work done = 60×10×4
work done = 2400 joules
Similarly
power = work/time
power = MGH/time
power=60×10×4/120
power=2400/120
power= 20watt
Hope it will help you :)❤

True or false scientific name tells you to family in which the organism belong
Answer:
False
Explanation:
A scientific name for a species is a unique name, which means that no species can have the same scientific name. The scientific name of a species tells you the genus and the species name of an organism. The genus comes first in the name and is the more inclusive group of organisms.
What happens to excess carbohydrates in animals?
They are stored as fat.
They are stored as protein.
They are stored in nucleic acids.
They are stored as sugar.
Answer:
A-They are stored as fat.
Explanation:
In animals, the excess of carbohydrates or glucose is first converted into glycogen (polysaccharide) through the process called glycogenesis. ... When glycogen reservoirs are saturated, excess carbohydrates, as well as proteins, are converted into fats which are then majorly stored in adipose tissues.

a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose.

As scientists advise about potential risks due to climate change, many coastal areas are preparing for a higher risk of impact Predict
which of these has a greater impact on human health in coastal areas due to climate change.
Since the coast water is rising,it would be hard to find fresh water. The people would not be able to use the water,because it would be contaminated with bacteria. If all of the ice does melt,most of the fresh water will turn to salt water,and we would have to adapt to a new way of life. People would have to live on higher land,there would be no one to grow crops,and their would be no way that trees would survive,meaning we would not be able to breathe.The worst part of this all is that the Earth's temperature will sky rocket,and it will be so hot,the Earth will kinda be like a huge hurricane.(lol)

is the black death airborne ?? apparently it isn’t but then why did ppl use those masks ?
The most common explanation of the transmission of the Black Death is flea bites. Infected fleas were carried on rodents, and these fleas transmitted the virus to humans.
There are still several different theories about how the Black Death was spread, however. There's a Wiki page called "Theories of the Black Death" that may be helpful.
At the time of the Black Death, bacteria and viruses hadn't been discovered yet. People thought that sickness was transferred through bad smells, which were called "miasma."
The long beaks of the masks were stuffed with strong-smelling herbs, spices, and dried flowers—lavender, roses, peppermint—which were thought to keep away the "evil" smells that were thought to cause disease.

Explain how an organ and organelles are related
Answer:
Just as organs are separate body parts that perform certain functions in the human body, organelles are microscopic sub-units that perform specific functions within individual cells. Organelles are specialized structures that perform various jobs inside cells.
Organelles are microscopic subunits that carry out certain tasks within individual cells, whereas organs are distinct body sections that carry out specialized tasks for the human body.
What is the relation between organ and organelles?Literally, the phrase refers to “tiny organs.” Organelles provide specialized functions to keep a cell alive, much like organs like the heart, liver, stomach, and kidneys serve specific functions to keep an individual alive.
Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization in the body, going from the simplest to the most complex.
Like an organ in the body, an organelle is a subcellular structure that performs one or more particular functions for the cell.
Therefore, organ and organelles differ in their functioning.
