Here are the answers to the questions respectively:
Physical exertion increase symptoms of poisoning by trematol because the generation of lactic acid through fermentation, and when liver enzymes are inhibited, the accumulation of lactic acid lowers blood pH.The pH of the blood decrease in a person who has digested trematol because exercise stimulates metabolism, and blood pH rises as a result of the electron transport chain pushing H+ out of the mitochondria.A metabolic poison called trematol is made from the white snake root. The toxin is concentrated in the milk of cows that consume this plant. The toxin prevents the liver's enzymes from metabolizing lactic acid into other chemicals.
Our cells make lactic acid through a process known as fermentation when there is not enough oxygen present. Particularly in our muscles, the pyruvate from glycolysis is converted to lactic acid to replenish NAD+ from NADH, allowing glycolysis to continue producing ATP. This explains why exercise makes the symptoms worse.

Why does a plant need to store glucose...
Answer:
Because glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source. That's why some foods that we eat, like rice and grains, are packed with starch.
Explanation:
Sugars facilitate the assimilation of nutrient elements and their transport by the plant since they reduce osmotic pressure, thus improving their entry into plant tissues. During vegetative development, transport takes place towards the stem and root tips.
in fruit flies, long wings (w) are dominant over short wings (w), and red eyes (r) are dominant over orange eyes (r). each individual possesses two alleles for each trait. if a fly that is homozygous dominant for both traits is crossed with a fly that is homozygous recessive for both traits, what is the predicted genotype of the offspring?
Option C If a fly that is homozygous dominant for both traits is crossed with a fly that is homozygous recessive for both traits, WwRr the predicted genotype of the offspring.
You inherited two identical copies of a gene if you are homozygous for that gene. The alleles are different, which is the reverse of a heterozygous genotype. Recessive features, such as red hair or blue eyes, are always present in individuals who are homozygous for that gene. Two chromosomal sets make up an individual human. Allele pairings are referred to as heterozygous and homozygous, respectively. The term "homozygous" refers to people who have two copies of the same allele (RR or rr). The term "heterozygous" refers to an individual organism with multiple alleles (Rr). Genes from each biological parent are inherited, which is referred to as homozygous or homozygosity. The mutation, which modifies the gene's DNA structure, causes the variation. Gene variations are known as alleles by experts. A person is homozygous if their alleles match exactly.

what happens when RNA is edited?
Answer: One type, insertion/deletion RNA editing, involves the insertion or deletion of nucleotides and actually changes the length of the target RNA. The second type, RNA editing by base modification, changes an encoded nucleotide into a different nucleotide, without changing the overall length of the RNA.
Explanation:
Answer:
Deamination produces an adenosine-to-inosine substitution, one of the most common substitutions in RNA editing.

Which two statements explain why water is vital to sustaining a healthy
ecosystem?
A. Water molecules consist of atoms of hydrogen and oxygen.
B. All of Earth's heterotrophs depend on water as a source of energy
for life processes.
C. Autotrophs need water in order to make oxygen gas and sugars
from inorganic matter.
D. Water enables energy to move through all of Earth's systems.
Water is vital in sustaining a healthy ecosystem as the Autotrophs need water to make food from inorganic matter and water enables the transfer of energy through the earth's systems.
While water is broken down to produce oxygen during photosynthesis, oxygen and hydrogen are combined to produce water during cellular respiration. While photosynthesis utilizes carbon dioxide and releases oxygen, cellular respiration uses oxygen and creates carbon dioxide. The oxygen that is released is used by most organisms, including humans, for cellular respiration.
There are three ways that liquid water travels through land and through the earth: runoff, infiltration, and percolation (groundwater). Groundwater is absorbed by plants, and as it evaporates, it reaches the atmosphere (transpiration). Snow and ice that is solid can suddenly become gaseous (sublimation).
So, water is necessary in sustaining life on earth.

how does photosynthesis transform solar energy into the chemical energy of sugar molecules? match the words in the left column to the appropriate blanks in the sentences on the right.
Photosynthesis will transform solar energy into organic matter thanks to a structure inside the cell called chloroplast.
How does photosynthesis transform solar energy into the chemical energy of sugar molecules?The light reactions occur in the thylakoids. Absorption of a photon boosts proton-motive force to a higher-energy state. The energy of light is used to pump an electron from water through photosystem II, an electron transport chain, and photosystem I to NADPH. During energy-releasing redox reactions in the electron transport chain, protons are pumped into the thylakoid space. ATP synthase uses this electrons to make ATP outside the thylakoid space.
The Calvin cycle occurs in the stroma.The three-carbon sugar G3P is produced and can be converted to sugars and other organic molecules, ultimately providing the chemical energy and carbon source for all of life.

Beneficial mutations be transmitted horizontally to other e. coli cells by means of transformation.
What is transformation?Bacterial transformation is the transfer of free DNA released from a donor bacterium into the extracellular environment, usually leading to the assimilation and expression of newly acquired traits in the recipient bacterium.
Transformation of bacteria relies on the natural ability of the bacterium to release DNA, which is taken up by another competent bacterium. Successful transformation depends on the competence of the host cell. Competence is the ability of cells to incorporate bare DNA into the transformation process. Intrinsically transformable organisms spontaneously release DNA by late stationary phase autolysis. Some bacteria, including Escherichia coli, have been artificially treated in the laboratory to use chemicals such as calcium, to apply strong electric fields (electroporation), or to apply heat shocks to induce phenotypes.
