Answer:
c. the distribution of genetic material into separate daughter cells may not occur equitably
Explanation:
Deoxyribonucleic acid, also known as DNA, is the genetic material in living organisms. It is found in the nucleus of eukaryotic cells. The DNA is, however, found to be wrapped around certain proteins to form an X-shaped CHROMOSOME structure during the process of cell division (mitosis and meiosis).
The purpose of this shape is to ensure that the daughter cells that results from cellular division processes receives an equal copy of the DNA in each chromosome. Hence, If DNA were not packed into X-shaped chromosomes, the distribution of genetic material (DNA) into separate daughter cells may not occur equitably/equally.
What is the effect of paraquat on ATP, NADPH,
and sugar?
Answer:
ATP will increase
NADPH will decrease
Sugar will decrease
Explanation:
Trust, and I just got this answer
The effect of paraquat on ATP, NADPH, and sugar includes the fact that ATP will increase, NADPH will decrease, and sugar will reduce.
Paraquat is also referred to as methyl viologen. It's a toxic chemical which is used as an herbicide for grass and weed control.
Paraquat can cause damage to one's health when it comes into contact with one's mouth or intestines.
It should be noted that biochemical changes that are caused by paraquat in the lungs will lead to rapid and prolonged oxidation of the NADPH. This then leads to the reduction in NADPH as it attempts to detoxify the lipid hydroperoxides. Also, paraquat will lead to an increase in ATP and a reduction in sugar levels too.

contrast cellular respiration and fermentation and explain which process is more efficient. why do your body's cells use fermentation during intense exercise?
Answer:
Cellular respiration produces 38Atp while fermentation produces 2 Atp, that being said Cellular respiration is more efficient than fermentation in the generation of ATP.
Explanation:
in fermentation, glucose reacts in the absence of oxygen to produce ATP. Cellular respiration is the more efficient process because it produces much more ATP from each glucose molecule than does fermentation. the body's cells use fermentation during intense exercise because their oxygen supply is limited
What would be the outcome of the processes shown below if the mRNA never moved outside
of the nucleus?
Answer:
Translation is the process of protein synthesis in which the genetic information encoded in mRNA is translated into a sequence of amino acids in a polypeptide chain
Ribosomes bind to mRNA in the cell's cytoplasm and move along the mRNA molecule in a 5' - 3' direction until it reaches a start codon (AUG)
Anticodons on tRNA molecules align opposite appropriate codons according to complementary base pairing (e.g. UAC will align with AUG)
Each tRNA molecule carries a specific amino acid (according to the genetic code)
Ribosomes catalyse the formation of peptide bonds between adjacent amino acids (via a condensation reaction)
The ribosome moves along the mRNA molecule synthesising a polypeptide chain until it reaches a stop codon, at this point translation stops and the polypeptide chain is released
Explanation:
The process of protein synthesis initiates with the transcription process in the nucleus and continues with the translation process in the cytoplasm. If the mRNA never left the nucleus, the translation would not be possible.
-------------------------------------
The protein synthesis process involves transcription and translation.
Transcription:
Transcription is the copying process of the DNA section for the desired protein occurs.It happens in the nucleus, where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.Once the transcription is over, the new mRNA molecule leaves the nucleus and goes to the cytoplasm.
Translation:
Translation occurs in the cytoplasm when mRNA meets a ribosome. rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein. While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide. Protein growth initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.
If the mRNA does not move outside of the nucleus, the translation process is not possible. Only transcription would occur, but no translation. Protein synthesis could not be accomplished.

9. In one or two sentences, describe how the available energy may affect the population sizes of organisms at different
trophic levels
Answer:
Explanation:
In food web energy are been transfered from the producer which are often plants down to the last individual on the web.
Each individual takes in and expels the remaining to the next until it is distributed to all. The amount of energy received from the producer will determine the amount of energy that will be available for others to share, when enough energy is transferred they all have enough to share but when the energy level is low the individual on the web also receive a low energy this may affect the population leading to a reduction,
It can also lead to competition among the organisms,migration out of environment to search for food. But When the energy level is high or on the increase it leads to growth and development among the organism.

nephron → urethra → bladder → ureter
urethra → ureter → bladder → nephron
nephron → ureter → bladder → urethra
urethra → bladder → ureter → nephron
Answer:
nephron → ureter → bladder → urethra
Answer:
nephron → ureter → bladder → urethra
Explanation:
The nephron, a functioning unit of the kidney, filters blood and is where urine is produced. Once there is urine, it empties into the ureter, a tube from the kidney to the bladder. The urine is then temporarily stored in the bladder until the body is ready to excrete the urine through another tube called the urethra.
The three components of RNA are a phosphate group, ribose sugar, and a nitrogenous base
How are the base pairs different?
Answer:
The nitrogenous bases Adenine (A), pairs with uracil (U), while guanine (G) and cytosine (C) pair up.
Explanation:
Nucleotides are monomers that make up DNA and RNA- these are nucleic acids that function as storage, transport and messenger molecules for encoding proteins. Nucleotides contain a 5-carbon deoxyribose (with hydroxyl modifications) or ribose sugar (RNA), phosphate and one of four nitrogenous bases:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T).- DNA only
Uracil (U) found in RNA
Nucleotide monomers derive their names from their bases. Nucleic acid polymers form on a single strand through covalent bonding. This occurs between two nucleotides in an esterification reaction where a phosphodiester bond is formed.
Nitrogenous bases encourage hydrogen bonding, and resulting base pair formation. Adenine (A), pairs with uracil (U), while guanine (G) and cytosine (C) pair up.

Which of the following would affect the function of an enzyme?
a.
all of these
c.
different substrates
b.
temperature
d.
pH
TEMPURATURE:
Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.
pH:
Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.
DIFFERENT SUBSTRATES:
Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

If you were making a product of artificial "Grow-Lites" for plants, what color light should
they emit so that plants can do photosynthesis (make sugars) most effectively?
Answer:
-blue and red light
Explanation:
Plants produce sugars or carbohydrates during the process of photosynthesis. They absorb light energy from the electromagnetic spectrum with pigments within the thylakoid membrane, like chlorophyll a, chlorophyll b.
Chlorophylls are made of ringed molecules chlorine, a hydrogenated form of porphyrin with a magnesium ion bonded to four atoms of nitrogen. Chlorophyll a shows the most absorption of red light (642 nm) and blue light (372 nm); while chlorophyll b shows the most absorption at 626 nm and 392 nm.
Different types of chlorophyll sidechains change the molecules' absorption ranges; A's methyl group is bound at carbon 7, B's aldehyde (CHO) ring is bound at carbon 7. Both absorb light from orange-red and violet-blue wavelengths. As such, the best light wavelengths for photosynthesis are within the blue and red wavelengths (425–450 nm) and (600–700 nm).

Complete question:
1. In Model 1 a pathogen (virus, bacteria, foreign protein, parasite) has entered the bloodstream of an individual. Describe the symbol that represents the pathogen.
3. Another type of white blood cell that is involved in the cell-mediated response is a helper T-cell.
a. Draw the symbol that represents the helper T-cell in Model 1.
b. In your drawing above, circle the specialized surface proteins on the helper T-cell.
Answer:
1. The pathogen is the one with the "star-like" symbol
3. a) The helper T-cell is represented like a Circle with the Th wrote inside.
b) The surface protein on the Th cell is the symbol that looks like this ⊥
or T Th cells.
Note: All the symbols are shown in the attached file.
Explanation:
Pathogens: These are invading the bloodstream, so you can see them among the white cells, and too many of them. Macrophages are one of the different types of white globules involved in the organism's defense against strange substances and pathogen agents. These cells are the principal actors in the immune response. Macrophages are the principal phagocytes of tissues, capable of recognizing different strange molecules that penetrate the organism, such as bacterias, parasites, and viruses. Macrophages phagocyte these substances and eliminate them, a process known as phagocytosis. Macrophages also have the capability of inducing an adaptative immune response. Macrophages show the antigens on their surfaces where they are recognized by lymphocytes.Helper T-cell: T-Lymphocytes are in charge of the regulation of the immune system. T-cells are the helper cells that coordinate the initial response in front of the pathogen. There are three types of helper T-cells: TH1 (lymphocyte T helper), TH2, and TH17. TH1 cells are highly effective during the elimination of intracellular pathogens.
