This question may be completed independently or as a group exercise. You have learned that humans have 46 total chromosomes, and chimpanzees have 48 total chromosomes. Use other textbooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you
Answer:
In comparison to humans, there are more chromosomes in the Hermit crab that is 127 pairs of chromosomes for a grand total of 254 and in Myrmecia pilosula has fewer chromosomes than humans.
The complexity of an organism or how advance is an organism has nothing to do with the number of chromosomes it had. The chromosome number is subject to change over time. Human ancestors had more chromosome numbers as compared to now but they are not advanced to us.

An exotic species is the same as an invasive species.
True
False
Answer:
False
Explanation:
Exotic species are species brought to and unfamiliar environment, just like invasive species. There is a difference between the two however. Exotic species are indeed not native to their environment, but unlike invasive species, they are not harmful to the ecosystem. In order for an exotic species to become invasive, it must out-compete native organisms for food and therefore cause harm to the ecosystem. Non-native species that do not out-compete species remain exotic and not a high risk of disrupting the ecosystem.

A plant and an animal are both living things. According to the Cell Theory, what can you conclude about these two
very different organisms? SC.912.L.14.1
Plants have cells but animals do not
They are both made of one or more cells.
They both come from the same kind of cell.
O They both come from a non-living organism.
Answer:
They are both made of one or more cells.
Explanation:
A plant and an animal are both living things. According to the Cell Theory, what we can conclude about these two very different organisms is that they are both made of one or more cells.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

What are some ways that stars can be different?
Answer:
hello
Explanation:
the star is the far from earth they are big as the not look from the earth .they look twinkel because of atomphere refraction which make the wavelengh of star into the increasing and decreasing wave when increase wave come to our eyes it look bright and when decrease it look dim while plant can not doAnswer:Their brightness is one of the 3 reasons on how you can tell them apart Their brightness is a factor of how much energy they put out–known as luminosity an also how far away they are from earth .Color can also fluctuate from star to star because Not all stars are the same temperature!Some are more cool and some are warmer!Hot stars appear white or blue, rather with cooler stars appear to have orange or red hues.We would normally think a orange or red would mean hot but no in this case!
What are stars made up of?
Stars are made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. All the dots of light we see in the sky are all light-years from Earth!
Solid or gas?
Stars are The first state is a solid and it is the coldest state of matter.
Are stars alive?!
No silly stars are not alive !Their “birth and death.” It's a convenient, if fanciful, way of describing the ultimately ill-fated relationship between matter and energy that is a star.
