Answer:
A cell is defined as the structural and functional unit of an organism.
The average size of the prokaryotic cell lies between 0.1 to 10 micrometers whereas the average size of the eukaryotic cell is approximately 25 micrometers.
Four things are found in all the cells: genetic material (either DNA or RNA), cell membrane, cytoplasm, and the ribosome.
All the living cells grow and reproduce (sexually or asexually) and have the ability to respond to stimuli.
Thus, characteristics of a cell may include: cell grows and reproduces, responds to stimuli, contains DNA or RNA, not both , and contains a cell membrane.
<span>Since alkylating agents work to prevent the cell from replicating its genetic material, the cell would most likely stop at the interphase checkpoint, which is the phase before mitosis (which consists of prophase, metaphase, anaphase, and telophase). During interphase, the cell replicates its genetic material (DNA), but this would be prohibited by alkylating agents.</span>
Answer:
The worst option of energy source for the rescue team would be - nuclear, hydroelectric, combustion and fuel burning all are worst option fro max to less worst.
Explanation:
The best option for the energy source for the rescue team would be hand canker, lever as it is mechanical energy generator does not require anything but hand movement to generate energy to charge equipment and easily carry anywhere.
Solar, wind energy are also helpful for rescue team but nuclear energy, hydropower, fuel burning energy source are risky, not handy and costly options.
Thus, the worst option are- nuclear, hydroelectric, combustion and fuel burning energy source.
Answer:
Tt - 1/2
tt - 1/2
Explanation:
<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>
Tt x tt
Offspring = Tt Tt tt tt (50% tall and 50% short)
If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):
Tt x tt
Offspring = Tt Tt tt tt
Genotype ratio = 2Tt:2tt
Hence,
Tt = 1/2
tt = 1/2
Answer:
a) Photosystem I requires the use of light converting an excited NADP + electron, reducing it to NADPH. In photosystems I and II, the passage of electrons to a series of redox reactions will be shown due to the absorption of light energy by the chlorophyll molecules.
(b) The control must be RuBisco, because for most photosynthesis responses to light, temperature and carbon dioxide, it produces oxygenation and carboxylation reactions, thus reflecting kinetic properties.
(c) plants can increase the ability in a variable ecosystem thanks to the flexibility of photosynthetic pigments, through these the necessary solar energy for photosynthesis is captured, according to each light spectrum there will be a specific pigment.
