If a cell has 46 chromosomes and undergoes mitosis, how many chromosomes will the resulting cells have
Answer:
Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

Describe how the available energy in the marine ecosystem of the pacific northwest could be different than that of the african savanna
The available energy in the African savanna is Higher than the available energy in the Marine ecosystem
The African savanna is located closer to the Equator and maintains a temperature of around 20 to 30° C due to the availability of enough sunlight reaching the soil and the vegetation found in the African savanna. also there is enough rainfall all year round.
The availability of sunlight and rainfall year round makes the energy levels in the African savanna higher than the energy available in Marine ecosystem.
The Marine ecosystem which consists of Freshwater water and salt water bodies have less sunlight penetrating through them and this negatively affects the available energy ( chemical / heat ) present in the marine ecosystem.
Hence we can conclude that The available energy in the African savanna is Higher than the available energy in the Marine ecosystem.

If double stranded DNA has 14% (guanine), what percent A (adenine), T (thymine) and C (cytosine) would you expect?
Answer:
If in a double stranded DNA the percentage of guanine is 14%, the percentage of the other bases of the molecule will be 14% for cytosine, 36% for adenine and 36% for thymine.
Explanation:
In the DNA molecule resides all the information of the genome of a living being, according to a specific sequence of nitrogenous bases adenine, guanine, cytosine and thymine. These bases are complemented -purine with pyrimidine- following the rule of base complementarity between one chain and another.
Knowing the percentage that exists of a base, the percentage or proportion of the other nitrogenous bases in a DNA molecule can be determined, approximately, following the rule of Chargaff's base pair.
Chargaff established in his observations that the DNA of a cell has a purine:pyrimidine ratio of 1:1, so there should be an equivalent amount of guanine for cytosin and a similar amount of thymine for adenine, since they are complementary bases.
According to the law of the base pair, if there is 14% in a DNA strand, there will be a 14% in the molecule:
Adenine 36%. Thymine 36%. Cytosine 14%. Guanine 14%. Total ..... 100%This rule applies to both chains, since the percentage of bases in a single chain will depend on the specific sequence of bases it has.

Answer:
Electron Transport Chain
Explanation:
For aerobic respiration, the electron transport chain or "respiratory chain" is embedded in the inner membrane of the mitochondria (see figure below).

What happens that makes rain start to fall from a cloud?
Answer:
when water vapor turns into clouds
Explanation:
Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice. ... In the cloud, with more water condensing onto other water droplets, the droplets grow. When they get too heavy to stay suspended in the cloud, even with updrafts within the cloud, they fall to Earth as rain.
The location of any electron in an atom can be described by
unique quantum numbers.
Answer:
Principal,subsidiary,magnetic,and spin quatum numbers
The given statement "The location of an electron in an atom can be described by unique quantum numbers." is true.
Quantum numbers, a series of specific numbers to describe the location of an electron of a particular atom. Quantum numbers define the features of the atomic orbitals and the electrons filled in those orbitals.
An electron in an atom or ion has four quantum numbers to describe its state are principal quantum number, azimuthal quantum number, magnetic quantum number, and spin quantum number.The electrons filled in the associated atom in the order of increasing energy of orbitals.1s 2s 2p 3s 3p < 4s <3d <4p < 5s < 4d <5p < 6s <45 < 5 < 6p...
Principal quantum number: explains the energy level of an electron. It is denoted by n. Azimuthal quantum number: explains the sub-shell of an electron. It is denoted by l. Magnetic quantum number: explains the energy levels of the sub-shell of an electron. It is denoted by -[tex]m_{l}[/tex]. Spin quantum number: explains the spin of an electron. It is denoted by [tex]m_{s}[/tex].Thus, the correct answer is - the statement is true.

What is the open area where an enzyme attaches called?
Answer:
The open area where the substrate is attached to an enzyme is called the active site.
Explanation:
The active site of an enzyme corresponds to the place where the tertiary structure of this molecule leaves a free space to couple the substrate and be able to catalyze a chemical reaction.
Since the enzyme-substrate complex functions as a key lock system, the active site has a three-dimensional configuration that only admits certain molecules as substrate, which determines its specificity.
The main organelle for photosynthesis is the

why are transgenic bacteria used to produce insulin? help, please!
Answer:
Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. ... There, the recombinant bacteria use the gene to begin producing human insulin.
Explanation:
A transgenic bacteria can produce insulin if it has the gene that produce insulin.
What are transgenic bacteria?There are bacteria that have been modified genetically.
This bacteria contains gene that have been transferred from other organism into them.

What usually happenstance an ecosystem after a sudden catastrophic change?
Please help
Answer:
Succession occurs after sudden catastrophic change.
Explanation:
In communities, organisms occupy specific niches. These gradually evolve over time as these organisms interact with their geosphere. In ecological succession, a community may undergo several dynamic changes. These include primary succession and secondary succession- these communities eventually try to achieve equilibrium over time.
After catastrophic events, the microorganisms, primary succession occurs. Here, a colonizing species exploits a non-habitable region. These eventually make the region more habitable through nutrient cycling, weathering, etc. which ushers in secondary succession. Here, the communities become more complex with time, becoming more varied and an increasingly large food web.
