Answer:
d. cellular respiration
Explanation:
mitochondria is where cellular respiration occurs, and photosynthesis occurs in the chloroplast, so d would be the most reasonable answer.
The ________ is the amount of times a cell can replicate before dying, and in humans it is about ______. A. Hayflick limit, 1000 B. Hayflick limit, 50 C. Division constant, 1000 D. Division constant, 50
Answer:
The answer is B. Hayflick limit, 50.
Explanation:
The Hayflick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis.
Leonard Hayflick developed the concept while at the Wistar Institute in Philadelphia, Pennsylvania, in 1965. In his 1974 book Intrinsic Mutagenesis, Frank Macfarlane Burnet named the concept after Hayflick. The concept of the Hayflick Limit helped scientists study the effects of cellular aging on human populations from embryonic development to death, including the discovery of the effects of shortening repetitive sequences of DNA, called telomeres, on the ends of chromosomes.

No they should not, heres why:
Explanation:
It has been proven on countless occasions that people forget details within minutes of an event. When you forget things, and you try to remeber, your brain will fill in the blanks with what it wants to see. In every case, if possible try to use hard evidence, ie: Videos, recordings, fingerprints, blood, and other stuff. If not that try to use multiple witness accounts and compare them.

The precursor of EGP is translated from a transcript that has had one non templated nucleotide added to the open reading frame. This change does not create or eliminate a stop codon. Compared with the protein sGP, which is produced from the unedited transcript, EGP most likely has the same primary:
Answer:
Explanation:
It was added somewhere in the middle. Since this is a frameshift, everything downwind of the addition will most likely be different.
The question is basically asking, if you change everything from the middle to the end of an amino acid sequence, which end changes and which end would remain the same?
It basically asks, when amino acids are assembled into proteins, are they built from the amino to the acid direction, or the acid to the amino direction?
The answer is that amino acid sequences are always assembled N to C, much like nucleotide sequences are built 5 to 3.
What is DNA??????????
Answer:
DNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. DNA is in each cell in the organism and tells cells what proteins to make. ... DNA is inherited by children from their parents.
Explanation:
DNA (Deoxyribonucleic acid) is a molecule present in the nucleus of cells of all living beings and that carries all the genetic information of an organism.
It is formed by a spiral-shaped double strand (double helix), composed of nucleotides.

Which test would be used to determine if lipids are present?
a) iodine test
b) none of these are correct
c) Benedict’s test
d) emulsion test
Option d) emulsion test would be utilized to determine if lipids exist present.
What is Emulsion test?The emulsion test exists as a method to determine the existence of lipids using wet chemistry. The procedure exists for the sample to be suspended in ethanol, permitting lipids present to dissolve. The liquid exists and is then decanted into water.
This test is accomplished to demonstrate the presence of lipids in a substance. The substance exists first dissolved in ethanol. This solution exists then dissolved in water. If lipids exist present in the mixture, they will precipitate and create an emulsion.
Hence,Option d) emulsion test would be utilized to determine if lipids exist present.

What is the best description of the word 'Variation' in biology?
O A. Differences between individuals of a species, and between different species.
OB. A large group of completely different items.
C. The differences between different parts of the same organism.
D. Change over time of a species.
Variation in biology is best delineate because the variations between people of a species, and between completely different species.
What is Variation?Variation refers to the variations or deviations from the recognized norm or commonplace. it's going to be a modification in structure, type or operate in associate degree organism, deviating from alternative organisms of identical species or cluster.
In genetic science, variation refers to a personal that possesses characteristics completely different from the others of identical kind. Genetic variation sometimes arises as a mutation sequence that encodes a super molecule or an polymer.
Variations is also mirrored within the composition of the individual, e.g. a distinction in size, color or pattern, or is also detectable solely by deoxyribonucleic acid or super molecule sequencing.
A given variant is also the results of changes during a single sequence, or the consequence of interactions among multiple genes. Populations of identical species living in several components of the globe is also characterized by specific sets of variations.
Variation will, therefore, be measured at the individual level, i.e. variations between individual individuals during a family or population, or at the population level, i.e. variations between populations living in several regions.
The different kinds of variations are:
Environmental factors - Composition variation known as environmental variation.
Inherited factors- The variation passed on from oldsters to offspring, via genes, throughout copy is named heritable variation.
What is Specie?A species is that the basic unit of classification associate degreed a assortment rank of an organism, furthermore as a unit of variety.
A species is outlined because the largest cluster of organisms within which any 2 people of the suitable sexes or sex activity sorts will turn out fertile offspring, usually by amphimixis.
Other ways in which of shaping species embody
- makeup,
- desoxyribonucleic acid sequence,
- Morphology,
- Behavior or condition.
In addition, paleontologists use the idea of the chrono species since fossil copy can not be examined

Explain how in glycolysis that the splitting of one glucose molecule results in 4 ATP but there Is only a net gain of 2 ATP.
Answer:
Explanation:
During glycolisys in cytoplasm, first step involves adding two phosphates to glucose molecule. This step requires the use of two ATP molecules. The next step is splitting 6 carbons glucose into two 3 carbons pyruvates. This step produces 4 ATPs and 2 NADHs. However, since we used up two ATPs during the initial phosphorylation, the net gain is only 2 ATPs

specific
A. fatty acid
B. amino acid
C. polypeptide
D. polysaccharide
Answer:
amino acid
Explanation:
The genetic code contains thousands of genes. Each genetic code represents a specific amino acid. Hence, option B is correct.
What is Genetic code?A genetic code represents a set of three-letter that are a combination of nucleotides known as codons. Each of them correlates to a particular amino acid.
Amino acids are the molecules that combine to form protein which serves as the base of life. Genetic code is translated into a sequence of amino acids with the help of a codon table.
Codon is a sequence of three nucleotides that form a unit of genetic code in DNA or RNA molecules.
Therefore, the amino acid is represented by each genetic code. Thus, option B is correct.
