What idea did Francis Redi's experiment with the meat and maggots disprove?
*
a. biogenesis
b. spontaneous generation
c. endosymbiosis
d. primordial soup
Answer:b
Explanation:
In the sealed jars, no flies, maggots, nor eggs could enter, thus none were seen in those jars. Maggots arose only where flies were able to lay eggs. This experiment disproved the idea of spontaneous generation for larger organisms.
What reactants are involved in photosynthesis?
A. H₂0 and CO₂ and sunlight energy
B. C₂H4O2 and H₂0 and chemical energy
C. H₂O and CO₂ and chemical energy
D. C₂H4O2 and H₂0 and sunlight energy
Answer: A
Explanation:
The three reactants used in photosynthesis are water (H2O) carbon dioxide (CO2), and light (sunlight energy). These reactants are used to produce glucose/food for plants and oxygen that is later released.
H₂0 and CO₂ and sunlight energy are reactants involved in photosynthesis. Therefore, option (A) is correct.
What do you mean by photosynthesis?Plants and other organisms use a process called photosynthesis to transform light energy into chemical energy that can later be released to power the organism's activities through cellular respiration.
C3, C4, and CAM (crassulacean acid metabolism) are the three primary types of photosynthesis. I had to learn some of their pathways and mechanisms.
Its is how green plants use sunlight to make food for themselves. Life on Earth cannot exist without photosynthesis. Without it there would be no green plants, and without green plants there would be no creatures.

What is the slope of the line? please help.
Answer:
The slope is [tex]\frac{4}{3}[/tex].
Explanation:
Slope is [tex]\frac{y}{x}[/tex], and to find it we need to look for where the line directly ends on the corner of the graph square. One occurs at (3,4), but the reason the slope is 4/3 and not 3/4 is because it is y over x. The y coordinate lines up at 4 and the x lines up at 3 getting you your answer of [tex]\frac{4}{3}[/tex]. I hope this helps! :) Sorry if this makes no sense- but the answer is 4/3.

If a scientist is conducting an experiment about obesity and asks a group of people to stop eating saturated fat, that group of people is called:
the control group.
the experimental group.
the qualitative group.
the quantitative group
Among the groups involved in an experiment, the experimental group is the one influenced by the independent variable -treatment-. Option B. Experimental group.
What is the experimental group?
During an experiment the researcher compares at least two groups: a control group and an experimental group.
Both of them are composed of individuals coming from the same population, so they are identical in all aspects except for the independent variables.
The experimental group is the one that receives the treatment. The researcher voluntarily changes the values of the independent variable to observe how it affects the individuals subjected. There can be several experimental groups.
In the exposed example, the independent variable is eating saturated fat.
Among all the individuals involved in the experiment, the group that stops eating saturated fat is the experimental group.
The researcher eliminates saturated fat from the diet of the experimental group to observe how it affects the weight of individuals.

On an rna molecule, which would base pair with adenine?.
Uracil
Explanation:RNA stands for ribonucleic acid. This helps with the expression of genes.
Bases of RNA
RNA has 4 different bases: adenine (A), uracil (U), cytosine (C), and guanine (G). Next to each base, you can see the symbol that represents the base. These bases are called nitrogenous bases because they contain nitrogen and act as a base (as opposed to an acid). These monomers are one of the building blocks of nucleic acids.
In RNA, adenine and uracil bond, and cytosine and guanine bond.
DNA
RNA and DNA are commonly confused because they perform similar jobs, but nonetheless, they are different. One reason they are different is that DNA does not have uracil. In DNA, adenine bonds with thymine (T).
