Answer: All told, the Krebs cycle forms (per two molecules of pyruvic acid) two ATP molecules, ten NADH molecules, and two FADH2 molecules. The NADH and the FADH2 will be used in the electron transport system.
Explanation:
All told, the Krebs cycle forms (per two molecules of pyruvic acid) two ATP molecules, ten NADH molecules, and two FADH2 molecules. The NADH and the FADH2 will be used in the electron transport system.
Kreb's cycle or Tricarboxylic acid cycle is a series of redox reactions, which take place in the mitochondrial matrix. The cycle yields energy in the form of GTP.
The carriers of the cycle are two ATP molecules, reduced 10 NADH and 2 FADH2, two carbon dioxide, and the initial product of two molecules of pyruvate.
The cycle can be described as:
The initial product is pyruvate, which is broken down into a two-carbon compound, acetyl coenzyme A to be utilized in Kreb's cycle. The series of reduction, hydration, oxidation, and dehydration results in the complete breakdown of the glucose.The products yielded from the cycle are carbon dioxide, GTP, NADH, and FADH2.The molecules NADH and FADH2 are the carriers, which are reoxidized in the electron transport chain, to yield overall energy in the form of ATP.Thus, the Krebs cycle yields NADH and FADH2, which enter the electron transport chain.

What benefit does an organism gain by only using this method of reproduction?
Explanation:
In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. On the other hand, the rapid rates of asexual reproduction may allow for a speedy response to environmental changes if individuals have mutations. An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce.
A ball is dropped from height of 45 m. A second ball is thrown downwards from the same
with an initial vity both the balls reach the ground at the same time, culate the value of u
Answer:
h = 45 m
g(acceleration due to gravity) = 9.8 m/s^2 or 10 m/s^2
Final velocity ( v ) = 0 m/s
v = ?
we know theirs equation of motion, v^2 = u^2 + 2gh
0 = u^2 + 2(-10)(45) [ The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.]
0 = u^2- 900
900 = u^2
u = √900 = 30 m/s

Explanation:
... Climate describes the long-term patterns of temperature and ... amount of sunlight, and amount of water that is available. Abiotic factors affect which ... Plants and animals that live in a particular biome have ... in taiga is thin, acidic, and nutrient-poor. Taiga.
Aquatic biomes are influenced by abiotic elements such as the presence of light, depth, stratification, temperature, currents, and tides.
What is aquatic ecosystem?In contrast to terrestrial ecosystems that are built on land, an aquatic environment is an ecology that is created around a body of water.
Communities of species that depend on one another and their surroundings make up aquatic ecosystems.
An aquatic ecosystem encompasses marine and freshwater habitats such as the ocean, intertidal zone, reefs, seabed, and freshwater habitats such as lakes, ponds, rivers, streams, wetlands, and swamps.
The habitat for all living things that require water, such as animals, plants, and bacteria, is the aquatic ecosystem.
A living thing that alters its surroundings is referred to as a biotic factor. Examples of organisms found in a freshwater habitat include algae, fish, amphibians, and aquatic plants. A particular ecosystem is the result of the interaction of biotic and abiotic components.
As aquatic biome abiotic factors include sunlight, temperature, nutrients, pH (acidity), depth, and salinity, if a chemical company were to dump a large quantity of acid into an estuary, this will increase the pH and also the salinity of water.
Thus, this will adversely affect the biotic life of the aquatic ecosystem.

As per the experimental values, When the temperature decreases the time taken for the starch to be digested increases. This means that when the temperature is decreased, the metabolic rate also decreases resulting in the decrease in the rate of digestion. As we decrease the temperature everytime by the value of [tex]10^0[/tex]C, the rate of reaction decreases by the factor of 2.

REASON:The reactants must contain sufficient kinetic energy to overcome a barrier called Activation Energy. Activation energy is the minimum amount of energy required to change the reactants into products. The Fastest reaction is at high temperature because when the temperature increases the molecules collide with one another more frequently, when the kinetic energy increases, more molecules make the effective collisions due to, so more molecules make up to the threshold energy. So increase in temperature increases the rate of the reaction.
_____________________________________A3)The optimum temperature for enzyme amylaze is 40 degree C because it has the fastest rate of reaction at that temperature. At high temperatures the shape of the enzyme is altered so that it is no longer complementary to its specific substrate., thus optimum temperature is 40 degrees, that is the reason why human body has temperature of 40.

Identify another method that could be used to determine the age of the fossil.
Explain why determining the age of the new fossil find is important to scientists.
Answer:
1) Index fossils are of organisms that lived over a wide area. They lived for a fairly short period of time. An index fossil allows a scientist to determine the age of the rock it is in.
2) Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.
Explanation:
Answer:
Some fossils, known as index fossils, help geologists balance rock layers. A fossil must be broadly dispersed to be a valuable index fossil and indicate a form of organism that has lived for a short time. Index fossils are valuable when the relative ages of the rock layers are told.

Using these words: cell division, Mitosis and DNA explain the product of mitosis and how it is achieved
Answer:
Mitosis is the process of cell division, that is, dividing one cell into two almost the same new cells, with the same number of chromosomes as the cell had when it began to divide.
Explanation:
Man contains 46 chromosomes in body (somatic) cells and 23 chromosomes in gametes. The process of division takes place in several phases: prophase, metaphase, anaphase, and telophase.
Before the cell division begins, the complete material is doubled, which will be divided into two "daughter cells" during the division.
This phase is called the interphase and it is the period between the two divisions. During this period, the cells grow and the amount of DNA doubles. Chromosomes are in the form of thin threads and are not visible.
Answer: Mitosis is a process in which a single cell divides into two identical daughter cells through cell division. During mitosis, one cell divides once to form two identical cells. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent's cell's cytoplasm. The major purpose of mitosis is for growth and to replace worn-out cells.

Explanation:
Less likely to be eaten by birds
The similarity in appearance between monarch butterflies and viceroy butterflies developed because viceroy butterflies that closely resemble monarchs are less likely to be eaten by birds. Thus, option B is correct.
What are viceroy butterflies?Limenitis archippus is scientific name of viceroy butterflies which is a North American butterfly. Since the viceroy is distasteful to predators, it is considered a Müllerian mimic.
The viceroy found in most of the contiguous United States as well as parts of Canada as well as Mexico. The caterpillar of viceroy butterflies feeds on trees in the willow family Salicaceae which includes willows, poplars, cottonwoods. The caterpillars isolate salicylic acid in their bodies, and therefore tastes bitter, and upsets predators' stomachs.
In natural phenomenon called Müllerian mimicry two or more well-defended species, which are foul-tasting and sharing common predators, mimic each other's honest warning signals.
Therefore, Monarch butterflies and viceroy butterflies are less likely to be eaten by birds so option B is correct.

How do algae blooms destroy aquatic life?
by giving off toxins that kill life
A harmful algal bloom (HAB) contains organisms (usually algae, hence the name) that can severely lower oxygen levels in natural waters, killing marine life.
What, besides temperature can make ocean water significantly denser
salinity
High salinity makes water denser. This is because there is more salt packed into the water. High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense.
Which area best describes a continental slope?
Continental slopes are regions of steeply sloping seafloor that lie between continental shelves and the deep ocean basins (Figure 2). Regional gradients are typically 2–5°, but locally slopes may be much steeper.
Algae blooms destroy aquatic life because of the decomposition of algae depletes oxygen needed by organisms.
How do algae blooms destroy aquatic life?When algae and bacteria in an algal bloom die, the decomposition process consumes the surrounding oxygen which leads no presence of oxygen in the water body and the aquatic organisms die because of suffocation.
So we can conclude that Algae blooms destroy aquatic life because of the decomposition of algae depletes oxygen needed by organisms.
