Answer:
Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies.
Explanation:
As rightly stated in the options of this question, the theory of Spontaneous generation is a theory that life forms can be generated from non-living or inanimate objects. Several scientists including Needham, Redi, Pasteur contributed to this theory experimentally by either proving or disproving it. Their contribution are as follows:
- John Needham boiled a broth containing living matter but noticed cloudy appearance representing microbial growth. Hence, when microbes grew in Needham's flask of broth, he proposed it was an example of spontaneous generation occurring in microorganisms.
- Francesco Redi, on the contrary, disproved the theory by conducting an experiment using meat. Redi DISPROVED the theory by concluding that flies were responsible for appearance of maggots on the meat. Hence, the statement that "Redi proved spontaneous generation theory by showing that maggots come from meat, not from other flies" is FALSE.
- Loius Pasteur also disproved the theory of spontaneous generation by using swan-necked flasks. His swan-neck flask experiment demonstrated that spontaneous generation does not occur

What group of organisms are closely related to archaebacteria
Answer:
The Archaea, single-celled organisms that often live in extreme environments, had been put together with the Bacteria, but molecular evidence reveals that they are widely separated. The Archaea are probably more closely related to the Eukaryotes, the branch that includes humans and most other familiar organisms.

explain how matter behaves differently than energy in a ecosystem
Answer:
Energy and nutrients are passed around through the food chain, when one organism eats another organism. ... An example of energy flow in an ecosystem would begin with the autotrophs that take energy from the sun. Herbivores then feed on the autotrophs and change the energy from the plant into energy that they can use.
How are luminosity and magnitude related?
(In your own words)
Answer:
Luminosity is an intrinsic(natural) measurable property of a star independent of distance. The concept of magnitude, on the other hand, incorporates distance. The apparent magnitude is a measure of the diminishing(decrease) flux of light as a result of distance according to the inverse-square law.

about exocytosis?
a. Help intake large material into the cell
b. Form of active transport
C. Occurs without help of cell organelle
d. It does not require energy
Answer:
B. Form of active transport
The statement that is true about exocytosis is that it is a form of active transport. That is option B.
Exocytosis is a cellular process where by materials especially waste products of metabolism or ions are moved from inside the cell to the outside of it.
An active transport is a process where by cells use energy to transport molecules across the cellular membrane.
There are different forms of active transport include:
EndocytosisexocytosisSodium Potassium Pump.Phagocytosis is the process by which cells transport large material into the, therefore Option A is False.
Golgi apparatus helps in exocytosis therefore option C is false.
Exocytosis requires energy, there option D is false
From the different forms of exocytosis listed above, exocytosis is a form of active transport because it makes use of energy.

Explanation:
Stomata are pores in the leaves of plants that allow gases to enter and exit the cells.
During the sunniest part of the day, the leaves are most actively performing photosynthesis.
During this time, which gas do the stomata allow into the leaf cells?
Answer:
carbon dioxide
Explanation:
In most plants, the roots absorb water from the soil. The water travels up through the xylem, a specialized layer of cells. In some plants, the water is absorbed through the leaves, directly from the air. Carbon dioxide, an atmospheric gas, enters the leaf through the stomata, the tiny pores in the leaves (a stoma is a single pore).
corruption is also shaped by our tolerance or our approach to answering societal problems
Yaa that's true...I totally agree with it
Yes, corruption occurs due to the tolerance of people.
Yes, corruption is shaped by our tolerance because the corrupt people do corruption when they know that people can't do anything or they are not arrested for their corruption then they do corruption. this is our tolerance which give them opportunity to do corruption.
If the people punished such type of person in public then no person will do corruption and the country or society experience more growth so we can say that corruption occurs due to the tolerance of people.

Which is the following is true about saturated fats?
a. They are typically solids at room temperature.
b. They are generally the healthiest fats to consume.
c. They cannot be broken down by enzymes.
d. By definition, they always contain one or more double bonds.
The following is true about saturated fats: they are typically solids at room temperature, which is in Option A, as they have a high melting point due to the absence of double bonds in their fatty acid chain.
What are saturated fats?Saturated fats are a type of fat molecule that consists of long chains of fatty acids. These fatty acids are called "saturated" because they are fully "saturated" with hydrogen atoms, that is, there are no double bonds between the carbon atoms in the fatty acid chain. This results in a straight, rigid structure that allows these fats to pack tightly together, which is why they are usually solid at room temperature.
Hence, the following is true about saturated fats: they are typically solid at room temperature, which is in Option A.

Which phases of the cell cycle are included in interphase? Check all that apply.
G1 phase
S phase
G2 phase
mitosis
cell division
Answer:
Interphase is the longest stage of the cell cycle and can be divided into 3 phases: G1 phase, S phase, G2 phase. The newly formed cell matures during the G1 phase. If the cell is going to divide, it enters the S (synthesis) phase where the DNA is replicated and the G2 phase where more growth occurs.
The interface is the first phase of the cell cycle during which the cell grows to its adequate level to start the duplication of its genetic material, the phases included in interphase are:
G1 phase.The cell physically grows, duplicating its organelles and the proteins needed for subsequent stages.
S phase.A complete copy of the cell's DNA is synthesized, as well as a duplicate of the centrosome, which will help separate the DNA in later stages.
G2 phase.The cell grows even larger, generates new proteins and organelles, and prepares for mitosis, cell division.
Therefore, we can conclude that the interface comprises the G1-S-G2 stages, and during them it grows to its proper level to start the duplication of its genetic material.

what is the reason why every living thing on earth
has the chance of survival?
1)When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?
2)What is it about the structure of ATP that contributes to its ability to act as an energy currency?
Answer/Explanation:
1) When phosphate is transferred from ATP, (which forms ADP and releases energy) it can phosphorylate another molecule. When this molecule is phosphorylated. It could become "energized" as it enters a higher energy state.
In this higher energy state, the protein has the energy to transfer molecules against a concentration gradient, which is an active process (requires energy).
2) Adenosine triphosphate contains three phosphate groups. The phosphate bonds are high energy. When ATP is hydrolyzed (water is added), these high energy phosphate bonds are broken and energy is released. This forms adenosine diphosphate (ADP).
1) When a protein molecule is phosphorylated, it becomes activated or powered and enables it transport molecules against their concentration gradient.
2) The bond that holds phosphate bonds in ATP gives it the ability to act as an energy currency.
ADENOSINE TRIPHOSPHATE (ATP)
Adenosine triphosphate, commonly known as ATP, is the means by which energy is stored and released in the cells of biological organisms. ATP is structurally made up of a ribose sugar, an Adenine base and three phosphate groups. The phosphate groups are held together by a bond called phosphoanhydride bond. ATP stores energy when one phosphate molecule is added to ADP while it releases energy when one phosphate group is broken. This latter process is called PHOSPHORYLATION. The ability of ATP to lose and accept phosphate group in its structure makes it perform the role of an energy currency in the cell.However, when a phosphate group is added to a molecule e.g. a transport protein, it is said to be phosphorylated. This means it will become activated or powered up to perform the task of transporting molecules against their concentration gradient.Learn more: https://brainly.com/question/15585148?referrer=searchResults
