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.
How are we able to tell from the results of this blood type test that this is 0+
Answer:
there's no test so... The test to determine your blood group is called ABO typing. Your blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked to see whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.

The diagram below shows a cell placed in a solution.
A cell is shown placed inside a beaker. It is labeled Cell. The solution inside the beaker is labeled 2% salt solution and the solution inside the cell is labeled 4% salt solution.
What will most likely happen to the cell?
It will expand as water moves out of it.
It will shrink as water moves out of it.
It will expand as water moves into it.
It will shrink as water moves into it.
The most likely to happen to the cell is ; ( C ) It will expand as water moves into it
The movement of water in and out of a cell is based on osmosis .The cell membrane of the cell will regulate the movement of water molecules in and out of the cell. based on the solute concentration inside the cell and outside the cell.
When a cell is placed in a hypotonic solution ( i.e. a solution with a lower solute concentration as seen in the 2% salt solution ) the water molecules from the hypotonic solution will move into the cell which will cause the cell to be Turgid/expand over time.
Hence we can conclude that the most likely thing to happen to the cell is ; It will expand as water moves into it

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.
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.

Fossils of canines were found on opposite sides of a mountain range. The fossils are from species that are anatomically similar, but the climates were extremely different on each side of the range. Which type of evidence for evolution do these fossils exemplify?
A. vestigial structures
B. analogous structures
C. coevolution
D. biogeography
The phenomenon described in the question is an example of coevolution.
What is coevolution?Evolution refers to the changes that occur in organisms as they metamorphose from one form to another over a given time interval. The changes that occur in one specie usually affects the changes that occur in related species. This is known as coevolution.
Hence, if fossils of canines were found on opposite sides of a mountain range and they belong to species that are anatomically similar, but the climates were extremely different on each side of the range, it is an example of coevolution.

Which processes produce the carbon dioxide from the original glucose molecule? Which processes do NOT produce CO2 molecules? (this is abt cell respiration)
The process that is responsible for the production of carbon dioxide from the original glucose molecule is known as Cellular respiration.
What is Cellular respiration?Cellular respiration may be defined as a biological process through which a form of sugar which is known as Glucose is transferred into energy in the form of ATP in the presence of oxygen. This energy is required to accomplish metabolic activities.
The complete reaction of cellular respiration is as follows:
Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP).The process that does not produce carbon dioxide molecules is the oxidation of food during respiration. In other words, it is known as Lactate fermentation. Lactate fermentation initiates with glycolysis and forms lactate.
Therefore, the process that produces carbon dioxide and the process that does not produce carbon dioxide is well described above.

what is the base-pair rule for a DNA strand matching an RNA strand?
Explanation:
The base pairing of guanine (G) and cytosine (C) is just the same in DNA and RNA. So in RNA the important base pairs are: adenine (A) pairs with uracil (U); Guanine G() pairs with cytosine (C).
The Chargaff rule only holds true for DNA. Base pairing doesn't take place since RNA is single-stranded. Consider a DNA strand.
What make base pair unique in DNA and RNA?Compare the two DNA strands' base-pair rules to this one. Since uracil is absent from DNA, T and A complement one another. In contrast, T bonds with A and A bonds with U in a DNA/RNA match.
Important: It serves as the foundation for base pairing. This rule can be used to both determine the DNA strand length and if a base is present in the molecule.
Adenine and thymine are always equal, and cytosine and guanine are also always equal, allowing us to calculate the percentages of each base.
It assists in figuring out the makeup and structure of DNA in various species. It is constant within a species.
Therefore, the base-pair rule for a DNA strand matching an RNA strand.

A diagram of meiosis I is shown below.
At which stage of meiosis I does the exchange in genetic material between homologous chromosomes result in recombinant chromosomes?
prophase I
metaphase I
anaphase I
telophase I
Answer:
The correct answer is - prophase I
Explanation:
Crossing over or recombination is the event that takes place during the pachytene stage of Prophase I of Meiosis I. During this event, the exchange in genetic material between non-sister chromatids of homologous chromosomes results in the recombination of the genetic material or recombinant chromosome.
Prophase I is the first stage which is characterized by the condensation of the chromosome and form tetrad and appeared to be X like structure in the cell and followed by the crossing over or genetic exchange of homologous chromosomes.

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.

A protein isolated from a thermophilic bacterium shows a molecular weight of 160 kD when eluted from a size-exclusion chromatography column, but when the purified protein is run on an SDS-PAGE gel, a single band of 80 kD is observed. These results tell us that the protein is eluting from the size-exclusion column as a
Answer:
as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions
Explanation:
SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.
