Explanation:
Mitosis allows for cells to produce identical copies of themselves, which means the genetic material is duplicated from parent to daughter cells. Mitosis produces two daughter cells from one parent cell. Single-celled eukaryotes, such as amoeba and yeast, use mitosis to reproduce asexuallyand increase their population. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

Salmonella typhi is a bacteria that reproduces by splitting into two
identical organisms. What type of asexual reproduction is this?
1Binary Fission
2O Vegetative Propagation
3Budding
4Fragmentation
Answer:
Binary fission
Explanation:
Binary fission is a type of asexual reproduction in bacteria in which two identical daughter cells arise from a new cell. It is asexual in the sense that it does not require two parents but only one.
According to this question, Salmonella typhi is a bacteria that reproduces by splitting into two identical organisms. This is evidently a type of BINARY FISSION reproduction by the bacteria cell.

Some individuals of a particular species of sea bird underwent a genetic mutation that resulted in larger beaks. The larger size of beaks helped
these birds to break open dams and other mollusks for food. It also helped them defend themselves against predators. After many generations,
almost all of the birds in the population had big beaks. For which two reasons did this phenomenon occur?
A. natural selection
B. mechanical Isolation
C. prezygotic barriers to reproduction
D. high genetic variation in the species
Answer:
The answers would be A and D I think
Explanation:
What is the difference between a species, a population,and a community
Answer:
A species is a group of organism that share genetic heritage and are Also able to interbreed.
Population can be defined as the total number of organism of the same specie living together in a habitat.
Community is made of all the population of living organisms that exist together in a habitat.

Why is water found in different phases on different objects in our solar system?
Earth is the only known planet to have bodies of liquid water on its surface. Europa is thought to have subsurface liquid water. ... Evidence points to water on other planets in our solar system. In 2015, NASA confirmed that liquid water flows intermittently on present-day Mars..
If a DNA strand contains 26% thymine, what percent adenine will there be in the
same DNA molecule?
Hint: use Chargaff's Rules
24%
27%
26%
23%
Answer:
26%
Explanation:
Adenine and Thymine are pairs. Therefore, they must have the same amount.
It must always equal 100% and base pairs always have the same amount. So in this case Adenine and Thymine would be 26% and Guanine and Cytosine would be 24%.
Test question: If a DNA strand has 10% Guanine how much Adenine would there be?
Answer: G-10, C-10, A-40, T-40= 100%

Water is the most abundant molecule found in living organisms. Most mammals, in fact, are approximately 70% water by weight. About two-thirds of this water is present inside cells. The other one-third is present outside cells (e.g., in blood plasma or other body fluids). Why is water so important to cells?
Answer:
Water is an essential constituent of the protoplasm of living cells because it is directly involved in countless biochemical reactions like photosynthesis and respiration. Without it cells couldn't move waste and by-products, take in nutrients, perform intracelluar transportation, functioning and signalling
Explanation:
When you want to move a part of your body, your brain sends a signal to
the muscles....
The muscles Contract and relax randomly
Contract and pull on bones directly
Contract and pull on tendons, which pull on the bones
Answer:
Contract and pull on tendons, which pull on bones
Explanation:
Muscles don't attach directly to bones. The tendons throughout our body serve as a connective tissue, connecting the two. Skeletal muscles, which seem to be attached to bones, are still only held there with the help of muscles.

in order to perform, a chemist needs an element that has similar properties to potassium (K) but has a lower atomic mass. which element should the chemist select for the experiment?
A. Robidium (Rb)
B. Sodium(Na)
C. Magnesium(Mg)
D. Calcium(Ca)
The element needed by the chemist to perform the experiment with similar properties to that of potassium, while having lower atomic mass is option B. Sodium.
If we take a look at the periodic table, we can see all the elements that share properties with potassium are located within the same column. Some examples are :
SodiumRubidiumCesium LithiumOf the elements listed, only two are found within the options for this question, which means that we can discard option C and D.
We can then proceed to analyze the atomic mass of each element in an attempt to choose the option with a lower atomic mass than Potassium. Option A, Rubidium, has an atomic mass that is much higher than the 39 of potassium, which means we can discard option A. The correct choice is option B, Sodium , since it shares similar properties and has an atomic mass of 22.

Explanation:
a large patch of warm water developed off the coast, creating a catalyst that has further changed this underwater environment. The persistent warmer sea temperatures stress the kelp forests to the point that growth and reproduction have slowed dramatically and caused damage to remaining fronds and tissue.
