Answer: ADP provide the building block for ATP.
ATP is the energy source, the molecule that carry energy for cells activities.
Explanation:
Cellular respiration refers to processes in which carbohydrates or glucose is breakdown to release ATP, energy for cellular activities.
Adenosine diphosphate contain nucleotide, ribose and two phosphate group.
Adenosine triphosphates (ATP) contain nucleotide, ribose sugar and 3 phosphate groups. When ATP is used for cellular respiration, a great energy is use to build the bond holding 3 phosphate group in ATP and it require great energy to break it down,once it is broken down it releases energy.
ATP carries energy and release it in the cells,once it has release energy it becomes ADP.
During the process of cellular respiration, glucose provide energy to build ADP and additional phosphate group to form ATP.
Answer:
ATP is consumed in glycolysis to convert glucose to pyruvate, and produced in electron transport chain.
Explanation:
Cellular respiration consists of three parts in order: glycolysis, Krebs cycle, and electron transport chain.
Glycolysis involves total of 10 steps. Out of those, step 1 and 3 use ATP.
In step 1, hexokinase (HK) take a phosphate from ATP and add the phosphate to glucose to create glucose-6-phosphate. Because a phosphate is taken out, ATP becomes ADP.
In step 3, phosphofructokinase (PFK) take a phosphate from ATP and add the phosphate to fructose-6-phosphate to create fructose-1,6-bisphosphate.
In last step, ATP synthase uses the difference in hydrogen ion concentration to make ATP.
NADH catalyzes a series of reactions with several proteins to move hydrogen cations from mitochondrial matrix to intermembrane space. This creates a difference in hydrogen cation concentration.
The higher concentration in intermembrane space means hydrogen cations prefer to go back to mitochondrial matrix.
ATP synthase use this force to drive reaction that adds a phosphate to ADP to create ATP.
B. Mutation
C. Independent assortment
D. Random fertilization
E. All of the above
Answer:
The correct answer is E. All of the above
Explanation:
Variation in offspring can be contributed by many different events that change the DNA sequence in gametic cells. These events are crossing over, mutation, independent assortment, and random fertilization.
During the gamete formation, the different genes are assorted independently from the other gametes which results in forming various possible combinations of genes in a gamete increasing the genetic variation.
Crossing over occurs during meiosis between the homologous chromosome that results in exchange of genetic material that brings genetic variation in gametes. During random fertilization, the two gametes fuse and genetic material of two different individual comes to make an offspring which forms a genetical different offspring.
Mutation in the gametic cell is transferred to the offspring during fertilization. Therefore all contributes to variation in offspring produced by sexual reproduction.
(b)haploid cells
(c)plant cells
(d)animal cells
Answer:
with no doubt I think the answer is diploid itdoes not access meiosis at all
Answer:
haploid cells
Explanation:
Answer:
B.8
Explanation:
In a dividing cell, each chromosome consists of two chromatids. Both the chromatids remain attached at the centromeres. If in a dividing cell there are 8 centromeres, indicates that dividing cell has 8 chromosomes. Chromosomes separate during anaphase. The cell is still dividing and not separated into two daughter cells. Therefore, if the cell has 8 centromeres during metaphase, the same number of centromeres will be present during anaphase. Thus, 8 is the correct answer.
The correct answer is - B) more; in total.
The urban areas use much more energy than the rural areas, by far. The reasons for that are numerous, with the two biggest being the number of people and the industry.
The number of people living in urban areas is higher than the number of people living in rural areas. Also, the people in the urban areas use much more energy because they rely on much more technology, technology that uses energy in order to work.
Most of the industry is also located in and around the urban places. The industry is a huge consumer of energy, thus increasing the usage of energy further more.
If the last cytosine is replaced by a guanine, the last amino acid will become tryptophan instead of cysteine.
UUG AUC CAA UGC.
UUG AUC CAA UGG.
This type of mutation that changes the amino acid is called missense mutation.
In humans, mutations of this type are responsible for diseases such as sickle cell disease. In plants, false sense mutations control, for example, the thickness of the hull of the oil palm fruit.
Answer:
non-foliated, metamorphic
Explanation:
Unlike quartz, an igneous rock which forms a crystal from magma or as a precipiate near hydrothermal vents, quartzite is formed from applying heat and pressure to sandstone, thus it is metamorphic. The intense conditions during its formation tightly compresses and interwinds the quartz grains, the resulting rock becomes hard and dense. As a non-foliated rock, quartzite does not show repeated parallel bands and it breaks across grains to split into flat layers.
Answer:
hey you!
Explanation:
Quartzite
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content. Quartzite generally comprises greater than 90% percent quartz, and some examples, containing up to 99% quartz, and are the largest and purest concentrations of silica in the Earth's crust. Although a quartz-rich sandstone can look similar to quartzite, a fresh broken surface of quartzite will show breakage across quartz grains, whereas the sandstone will break around quartz grains. Quartzite also tends to have a sugary appearance and glassy lustre. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during metamorphism. Although quartzite can sometimes appear superficially similar to marble, a piece of quartzite will not be able to be scratched by a metal blade, and quartzite will not fizz on contact with dilute hydrochloric acid.
Texture - granular.
Grain size - medium grained; can see interlocking quartz crystals with the naked eye.
Hardness - hard.
Colour - variable - pure quartzite is white but quartzite exists in a wide variety of colours.
Mineralogy - quartz.
Other features - generally gritty to touch.
Uses - pure quartzite is a source of silica for metallurgical purposes, and for the manufacture of brick; as aggregate in the construction and roading industries; as armour rock for sea walls; dimension stone for building facings, paving etc.
