Answer:

Explanation:

The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP. Some of the energy released is lost as heat.

The release of energy from carbohydrates takes place within the

mitochondria.

The mitochondria is an organelle found within cells and it is regarded as

the power house of the cell. This is because energy is generated in it which

gives the cells power to perform its daily activities.

Energy generated from carbohydrate is usually in the form of ATP and it

involves series of reactions such as glycolysis, kreb cycle etc to ensure

adequate energy yield.

Answer:

It's B

Explanation:

Answer:

C is the correct option.

Explanation:

Cells in the body continue to produce ATP in absence of oxygen.

Lactic acid fermentation is most likely to occur in the swimmer's cells so that the process of glycolysis can continue to produce ATP. Thus, the correct option is C.

Lactic acid fermentation is a metabolic process in which glucose or other six-carbon sugars are converted into cellular energy (ATP) and the metabolite lactic acid. It is an anaerobic fermentation reaction which occurs in some bacteria and animal cells, such as muscle cells and in absence of oxygen molecule.

Lactic acid fermentation happens in the skeletal muscles. In this process, pyruvate is converted to lactic acid by  the lactate dehydrogenase enzyme when oxygen is inadequate. Fatigue is brought on by the formation of lactic acid which buildup in the muscles.

Therefore, the correct option is C.

Answer:

The Supreme Court decided that the President was required to turn over tape recordings and other materials that had been subpoenaed by special prosecutor Leon Jaworski.

In trying to withhold some materials related to the Watergate investigation, Nixon's lawyer had argued that the President of the United States "is not subject to the processes of any court in the land except the court of impeachment." The Supreme Court disagreed, in unanimous fashion. They held that the President could not use executive privilege as an excuse for hiding wrongdoing or avoiding prosecution. In an interview some years after his resignation, Nixon still held to his view, claiming that when the President does something, "that means that it is not illegal." He felt that being in the position of President put him above the law. But the Supreme Court had firmly disagreed. They rejected the idea of "absolute, unqualified Presidential privilege of immunity from judicial process under all circumstances." Executive privilege can only protect matters of military or diplomatic confidentiality

Answer:

peaks and valleys show population increase and decrease between 2 species or more.

Explanation:

the peaks and valleys are used to show predation hence if there is an increase in prey there will be an increase in the predators and if there is a decrease in prey there will be a decrease in predators therefore creating peaks and valleys in that graph hence demonstrating population interactions between the two species.

Answer:

The correct sequence of events that occurs during protein synthesis? A

Explanation:

2. DNA is used as a template to create mRNA, which leaves the nucleus

4. mRNA molecule binds to a ribosome

1. tRNA brings the correct amino acid specified by the mRNA codon

3. Amino acids are bonded together to make a polypeptide (protein)

5. The ribosome releases both the mRNA molecule and the polypeptide (protein)

During protein synthesis, all the machinery for synthesis occurs in a sequential manner and the first need is a DNA template, so the correct option is a.

Protein synthesis occurs in the ribosomal machinery and the process is called translation and starts after transcription.

DNA acts as a template for transcription and makes mRNA which translates into protein. mRNA act as a messenger for protein synthesis, this mRNA converts into protein with the help of ribosomal machinery.

In the process tRNA act as an adapter molecule adding an amino acid to the protein chain according to the codon on mRNA. In the last step protein and mRNA are released by the ribosome.

Therefore protein synthesis starts with DNA, hence option a is correct.

Answer:

G2/Growth 2 phase

Answer:

When a cell's DNA is damaged, a sensor protein activates p53, which halts the cell cycle at the G 1start subscript, 1, end subscript checkpoint by triggering production of a cell-cycle inhibitor. This pause buys time for DNA repair, which also depends on p53, whose second job is to activate DNA repair enzymes.

Answer:

If crossing over doesn’t occur, then 2 out of the 4 daughter cells would be identical.

We have 46 chromosomes and are diploid meaning we got 1 set (23 chromosomes) from our mom and 1 set (23 chromosomes) from our dad.

In prophase 1, homologous chromosomes associate (chromosome #1 from dad and chromosome #1 from mom. They both code for the same things, but they are NOT identical)

Let’s compare mitosis to meiosis

On the left, see how in mitosis all chromosomes (even homologous) line up in single file (imagine all 46 lining up individually). When anaphase splits the sister chromatids (which are identical) in mitosis, each daughter cell gets the exact same genetic info.

(they get both homologous chromosomes: 1 from dad (yellow)and 1 from mom (purple) resulting in a full diploid set)

On the right in meiosis, see how the homologous chromosomes associate and will split? Chromosome #1 from mom (purple) is going to the left daughter cell while chromosome #1 from dad (yellow) is going to the right daughter cell. This means the two daughter cells will only have 1 set for chromosome #1 (either moms or dads but NOT both) and become haploid (1 set of 23 chromosomes)

Again in mitosis, all 46 lined up individually, but in meiosis the 23 from mom and 23 from dad first associate and each orient to decide which daughter cell gets the dads chromosome or the moms chromosome. They assort independently meaning just because dads chromosome #1 went to the left DOESN’T mean that dads chromosome #2 or #3 will go to the left. This gives a unique pattern of 23 chromosomes for the 2 daughter cells of meiosis 1 (a various mixture of moms and dads, but it is possible to result in a daughter cell with just moms and just dads set, though this would be a very small probability like 1 in 2^23 )

So each daughter cell of meiosis 1 is a haploid set (only 1 set instead of 2) and the opposite of the other (since 1 has fathers while the other has mothers for the same chromosome)

Meiosis 2 is just like mitosis. Here the sister chromatids separate producing 2 identical daughter cells

(identical if crossing over doesn’t occur. Crossing over only occurs on adjacent homologous chromatids)

If crossing over doesn’t occur then both sister chromatids are identical so that 2 out of 4 daughter cells will be exactly identical haploid sets. The other 2 are identical to each other as well.

Answer:

Water has cohesive and adhesive properties.

Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.

Adhesion and cohesion are important water properties that affects how water works everywhere, from plant leaves to your own body. ... Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.

Answer & Explanation:

The difference in electronegativity between oxygen and hydrogen atoms creates partial negative and positive charges, respectively, on the atoms.

Water molecules attract or are attracted to other polar molecules.

Molecules that do not dissolve in water are known as hydrophobic (water fearing) molecules.

Because of its extensive hydrogen bonding, water (H2O) is liquid over a far greater range of temperatures that would be expected for a molecule of its size. Water is also a good solvent for ionic compounds and many others because it readily forms hydrogen bonds with the solute.  

Cohesion holds hydrogen bonds together to create surface tension on water.

Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.

Water is transported in plants through both cohesive and adhesive forces; these forces pull water and the dissolved minerals from the roots to the leaves and other parts of the plant.

Key Terms:

hydrogen bonds: A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

adhesion: The ability of a substance to stick to an unlike substance; attraction between unlike molecules

cohesion: Various intermolecular forces that hold solids and liquids together; attraction between like molecules

hydrophilic: having an affinity for water; able to absorb, or be wetted by water

hydrophobic: lacking an affinity for water; unable to absorb, or be wetted by water

polarity: The intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule.
