Explanation:
Which letters are broken down to produce energy for cells?
Answer:
C and D
Explanation:
All living organisms need energy, which is produced by the breakdown of the food ingested in a process called CELLULAR RESPIRATION. Cellular respiration, which is the process whereby energy in form of ATP is synthesized, occurs in the MITOCHONDRIA.
However, the products of cellular respiration (CO2 and H2O) are used as reactants by plants to produce glucose and oxygen in their CHLOROPLASTS. The glucose and oxygen are broken down in the MITOCHONDRIA to yield energy by cells.
In this image, letters C and D represents glucose and oxygen, which are products of photosynthesis in the chloroplast. Glucose and oxygen represented by C and D are broken down to produce energy for cells in the mitochondria.

Griffith found that this combination of Streptococcus pneumoniae strains was highly severe.
Live R strain + Heat-killed S strain
Live T strain + Live S strain
Heat-killed R strain + Live S strain
Heat-killed R strain + Live R strain
Answer:
Live R strain + Heat-killed S strain
Explanation:
The R strain, in its live version, was nonvirulent. The ordinarily virulent S strain, when killed by heat and injected into the mice, became nonvirulent. However, when the mice were injected with both the nonvirulent R strain and the heat-killed S strain, the mice died.
Griffith found in his experiment that the following strain combination of Streptococcus pneumoniae strains was highly severe.
Live R strain + Heat-killed S
What was Griffiths experiment?Frederick Griffith performed one of the first tests to demonstrate that cells contain genetic material in 1928.Griffith's experiment used two pneumococcus strains: a deadly virulent strain (S) and a non-virulent strain (N) (R)Griffith infected mice with a non-virulent strain of bacteria (strain R) and found that they survived.Griffith used the pathogenic bacteria (strain S) to infect mice, and the mice died.Griffith infected mice with deadly bacteria (strain R) that had been heat-killed, and the mice survived because the bacterium had been killed.Griffith discovered that mice infected with a mix of heat-killed strain S and live strain R died.
Griffiths deduced from this that the live R cells had been converted into pathogenic S cells.

What would happen to the concentrations of Pyruvate, NADH and intermembrane H+ if the ETC stopped working?
Answer:
"Proton decreases" would be the right approach.
Explanation:
The Kreb cycle or system plays a key role throughout a matrix of mitochondria. 3 NADH, 2 FADH2 as well as 1 ATP are synthesized. Whenever the Kreb process has been halted, the acetyl CoA throughout the Kreb cycle has not been used. Pyruvate doesn't at all, disintegrate via acetyl CoA. Therefore in cells, pyruvate accumulates. Unless the Kreb loop is halted, therefore the concentration of NADH and FADH2 declines.Thus, they aren't used for the transportation chain of electrons. This is also why protons have not been discovered to be injected towards intermembrane space.

Explanation:
The image attached to this question represents a CELL, which consists of structures that performs specific functions called ORGANELLES. The organelle labelled B in particular is called a MITOCHONDRION. A mitochondrion is a double-membraned organelle i.e. it structurally has two membranes.
The mitochondrion is functionally the organelle where cellular respiration, which involves the synthesis of energy for the cell's metabolic activities, takes place. Hence, the statement that correctly differentiates between the structure and function of organelle B is: This organelle is composed of two membranes,reactions inside it release energy that can be used for cell processes
1. Which of the following are components of all cardiovascular systems? Select the THREE answers that are correct.
a series of tubes
an organ for gas exchange
a circulating fluid
a cavity for nutrient and gas exchange
a pump
2. Why do larger animals have closed circulatory systems?
Closed circulatory systems feature a smaller network of blood vessels than open circulatory systems, which allows for more targeted delivery of oxygen and nutrients to cells
Closed circulatory systems do not have chambers in the heart, which lessens complexity in the system and increases efficiency in oxygen and nutrient delivery.
Closed circulatory systems are less complex than open circulatory systems such that oxygen and nutrients are delivered to cells more quickly.
Closed circulatory systems allow for mixing of blood with other bodily fluids, which increases the rate at which oxygen and nutrients are carried to cells.
• Closed circulatory systems deliver oxygen and nutrients to cells and carbon dioxide and waste from cells more efficiently than open circulatory systems.
Answer:
for no.1
✓a circulating fluid
✓a pump
✓cavity for nutrient and gas exchange
for no.2
Closed circulatory systems allow for mixing of blood with other bodily fluids, which increases the rate at which oxygen and nutrients are carried to cells.
what is respiration
Respiration is a metabolic process common to all living things. Here, you will learn the definition, location, processes, and formula for cellular respiration. At the end, you can test your knowledge with a short quiz.
What is Respiration?
When you hear the word 'respire,' you probably think of breathing. When you breathe, you are taking in oxygen with each inhale and releasing carbon dioxide with each exhale. This gas exchange is important for respiration, but while breathing is a physical process, respiration can be thought of as more of a chemical process. All organisms, from a single bacterial cell to a coral reef colony to a blue whale, undergo respiration.
Food molecules absorbed after digestion are taken in, broken down, and the energy freed in the process is used to power the organism's movements and physiological functioning. Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells).
When we examine the equation for cellular respiration, we see that the reactants are glucose and oxygen (for aerobic respiration), and the products are carbon dioxide, water, and ATP. Note the number of oxygen, carbon dioxide, and water molecules involved in each 'turn' of the process.
respiration formula
Balance with Photosynthesis
Respiration is the antithesis to the process of photosynthesis, in which carbon dioxide and water are taken in by autotrophs, along with sunlight, to make glucose and oxygen. Autotrophs include any photosynthesizing organisms, such as plants and algae, all of whom also undergo respiration. The products of photosynthesis are taken in by heterotrophs, organisms who cannot make their own energy and rely upon autotrophs for food. The byproducts of their respiration - carbon dioxide and water - are then used for photosynthesis. In a balanced ecosystem, this exchange is an example of a negative feedback loop.

Three Phases of Respiration
In prokaryotic cells, respiration takes place in the cytosol and across the cell plasma membrane. In eukaryotic cells, it occurs in the cytosol and in the mitochondria. Mitochondria are the powerhouses of eukaryotic cells, and contain high surface areas of membrane folds on which respiration activity can be maximized.

1.occurs in fluids
2. requires physical contact between molecules
3.occurs in solids
4. is the method of heat transfer used by the Sun
Answer:
The answer is 1: Occurs in fluids.
Explanation:
Convection happens when a lot of heat in fluids/gas move and/or take the place of particles with less heat.
Answer:
1. occurs in fluids
Explanation:
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

After pollen grows a tube down the style, _____.
A: egg cells unite with an embryo
B: chromosomes slpit in half
C: the pollen sticks to the stigma
D: sperm cells travel to the ovary
Answer:
After pollen grows a tube down the style, sperm cells travel to the ovary (option D).
Explanation:
In angiosperms, the pollen grain contains the male gametophytes that are transported to a flower for pollination to occur.
Once the pollen reaches the stigma of a flower, from it grows a tubal extension, called a pollen tube, which grows into the ovary. The pollen tube allows male gametophytes (sperm cells) to come into contact with female gametophytes (eggs) to fertilize them.
The other options are not correct because:
A. Egg cells do not attach to the embryo, but to the sperm to produce that embryo.
B. Chromosomes split in half occurs in cell division.
C. Pollen sticks to stigma is a process that occurs before the pollen tube is formed.

Why perform multiple tests in order to identify an unknown bacterium, instead of a single biochemical test
Answer:
There is no specific test available for a perticular or any individual bacterium to be identified. A prticular test can only narrow down the choices on the basis of characteristic each test excludes or includes.
Most of the time, to identify a particular bacterium atleast 3 to 4 tests are required. Each test can give postive result to be positive for a new group of bacteria.

DNA damage can occur as a result of exposure to chemicals or ultraviolet radiation. What happens during nucleotide excision repair of damaged DNA? A. Enzymes delete an incorrect DNA sequence, pull the gap closed, and join the bases on either side of the gap together B. Enzymes cut out the damaged gene, copy the same gene from the homologous chromosome, and insert the copy C. Enzymes detect an incorrect DNA base pairing in a DNA strand, remove the incorrect base, and insert the correct base. D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Answer:
D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Explanation:
From time to time, the DNA gets exposed to certain chemicals or radiation that damages it. However, the cell has a DNA repair mechanism in place called NUCLEOTIDE EXCISION REPAIR (NER).
NUCLEOTIDE EXCISION REPAIR (NER) is one of the DNA repair mechanisms in which certain enzymes open the DNA strand, remove a segment of DNA that contains the damaged gene or nucleotide bases, and resynthesize the correct DNA sequence using the pair of the damaged one.
Felicia observed that the lettuce plants in her garden had wilted after several days of drought. The
next day, there was a downpour of rain, and the leaves began to swell. What cellular process caused
this effect in the lettuce plants?
Answer:
Due to the chought water was released from the plant which caused the plant to shrink or wilt.
Explanation:
Roots take water from the environment through osmosis. This is the diffusion of water molecules from a less concentrated solution to a more concentrated one. Osmotic process caused this effect in the lettuce plants.
---------------------------------------------------------
Osmosis is the phenomenon that occurs when two dilutions of different concentrations are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.
Water goes from the most diluted solution to the cell interior until concentrations are equal on both sides. At this point, the cell and the solution are in dynamic equilibrium.
As water enters, the cell begins to enlarge and becomes bigger-sized. It acquires turgidity.
Under natural conditions, the organism regulates the extracellular fluids to avoid cells swelling until they burst.
In the exposed example, the lettuce plants had lost water due to several days of drought. They were dehydrated.
Immediately after the downpour of rain, the plant cells acted as the more concentrated solution, separated by their membrane with a less concentrated solution.
Water molecules moved toward the most concentrated side, the interior of the cell.
Roots took water from the soil by osmotic process and drove it to the different plant tissues, rehydrating the cells.
