Answer:
Light energy
Explanation:
Light is light, light is not defined by an element. So it can't be changed into anything unless photosynthesis or any other chemical reaction.
In eukaryotes, general transcription factors A) are required for the expression of specific protein-encoding genes. B) bind to other proteins or to a sequence element within the promoter called the TATA box. C) inhibit RNA polymerase binding to the promoter and begin transcribing. D) bind to sequences just after the start site of transcription.
Answer:
B
Explanation:
The general transcription factors bind to other proteins or to a sequence element within the promoter region known as the TATA box.
Transcription is a biological process involving the synthesis of RNA from a DNA template. The process of transcription begins with the binding of an enzyme, the RNA polymerase, to the promoter region of a gene. Prior to that, however, a group of enzymes known as the transcription factors must bind to a specific sequence within the promoter region - the TATA box. The binding of the RNA polymerase signals the unwinding of the section of the DNA to complete the initiation complex.
The correct option is, therefore, B.

The creation of new crust at the middle of mid-ocean ridges is also
referred to as... *
A.mountain formation
B.sea floor spreading
C.fault formation
D.a transform boundary
Answer:
B.sea floor spreading
Explanation:
The creation of new crusts at the middle of the mid- ocean ridges is also sea floor spreading.
The process of sea floor spreading entails the creation of new crusts at the margin of the oceanic crusts.
Basaltic materials from the subsurface upwells to the surface.
They cool and solidifies to form new crusts. The old crust is moved behind and away from the margin. This way, sea floor is formed and it spreads in like manner.
At this margin sea floor is created and at a convergent margin, it is destroyed.

Which of the following best explains the endosymbiosis theory of how eukaryotic cells originated, as shown below? A.Eukaryotic cells developed from mutations in prokaryotic cells
B.Eukaryotic cells developed from organic compounds carried to Earth by debris from space
C.Eukaryotic cells originated from a combination of gases and heat in the atmosphere
D. Eukaryotic cells were originally large prokaryotic cells that absorbed smaller prokaryotic cells
Answer:I’m sure the answer is D
Explanation:
All eukaryotes evolved from prokaryotes and eventually developed into mitochondrial organelles.
The endosymbiotic theory represents that some of the organelles in eukaryotic cells were prokaryotic microbes at some time. As per the endosymbiosis theory the eukaryotic cells were at first large prokaryotic cells that absorbed smaller prokaryotic cells.
What is endosymbiosis?Endosymbiosis is the engulfing of the cell by another one to produce, over time, a coevolved relationship in which none of the cell could survive alone.
It is an evolutionary theory that guides the origin of eukaryotic cells by prokaryotes.
Eukaryotic cells were previously large prokaryotic cells that actually absorbed smaller prokaryotic cells
Thus, the correct option is D.

October 1, 2017 marks 27 years since the beginning of the Human Genome
Project. The goal of the group was to map the entire 3 billions bases and
80,000 genes in the human genome. On April 14, 2003, it was announced
that the goal was accomplished. Using this information, scientists have been
able to predict the risk of genetic diseases and understand the process of
inheritance. Which of the following statements best describes the process of
using the genetic code to produce polypeptides (proteins)?
Translation is used to produce a strand of RNA and proteins from a single strand of DNA.
O RNA produces a strand of DNA through transcription, then the DNA builds a protein molecule
through translation
O A single strand of DNA is used to make mRNA using translation, then the mRNA provides the
template for producing a protein through transcription
O A single strand of DNA is used to produce mRNA through transcription, then translation provides
the code for bonding amino acids to make a protein.
Answer:
The last one. A single strand of DNA is used to produce mRNA through transcription, then translation provides the code for bonding amino acids to make a protein.
Explanation:
Educated guess, but also. Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins.

What happens during Prophase I? You will need to think about what you learned during mitosis to fully answer the question.
DNA coils into chromosomes
Crossing over
Nuclear Membrane disappears
Chromosomes line up in the middle of the cell
Answer:
Crossing over
Explanation:
Prophase I is the first stage of meiosis I, it is the longest phase of meiosis. Crossing over (also known as recombination) can be defined as the process of exchange of genetic material between non-sister chromatids that occurs during Prophase I. Crossing over represents a critical source of genetic variation in offspring (the other one is the random orientation of the homologous chromosomes pairs). After crossing over, the resulting haploid (n) gametes aren't genetically identical to one another.

TT Tt Tt tt
Assuming that T is dominant over t:
Genotype ratio = 1TT:2Tt:1tt
Phenotype ratio = 3:1
2. Rr x Rr
RR Rr Rr rr
Assuming that R is dominant over r:
Genotype ratio = 1RR:2Rr:1rr
Phenotype ratio = 3:1
3. Assuming that green (G) is dominant over the other color (g). Heterozygous green would be Gg
Gg x Gg
GG Gg Gg gg
Genotype ratio = 1GG:2Gg:1gg
Phenotype ratio = 3:1 (green ratio the other color)
4. Assuming that green (G) is dominant over the other color (g) as above:
homzygous green plant = GG; heterozygous green plant - Gg
GG x Gg
GG Gg GG Gg
Genotype ratio = 1GG:1Gg
Phenotype ratio = 100% green
5. Assuming that tall (T) is dominant over short (t)
Homzygous tall plant = TT
short plant = tt
TT x tt
Tt Tt Tt Tt
Genotype ratio = 100% Tt
Phenotype ratio = 100% tall

Explain the basis for the great diversity of proteins in living organism.
Answer:
Explanation:
Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks. Protein synthesis involves building a polymer of amino acids with complex three-dimensional structure. Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule.

1. Which of the following is an example of a mutation?
ANSWER: a. A red blood cell loses its nucleus
b. A zygote receives two X chromosomes
c. A strand of mRNA is produced from DNA
d. A nucleotide is missing in a replicated DNA
Answer:
A
Explanation:
Quite simple actually. When a blood cell loses its nucleus it has no type of genetic code in order for it to function. With no DNA or Nucleus, the organelles inside the cell serve no purpose. This causes the cell to either swole or shrink. This is a form of mutation. This happens when there is no activity in the cell and it loses its proteins in the cell membrane, which leads the cell to use passive homeostasis more often than active. With no genetic code for it's cell transport, the cell gives out more necessary molecules, or takes in more necessary molecules.
If a nucleotide is missing in a replicated DNA, it would lead to a change in the gene expression which would lead to mutation. The correct answer is option d.
An alteration in the DNA sequence is known as a mutation, which can happen spontaneously or as a result of toxins or radiation. An organism may experience no effect, negative consequences, or positive effects as a result of a mutation.
Option d here refers to a mutation in which a nucleotide is absent from a DNA molecule that has been duplicated. The building components of DNA are called nucleotides, and if one is absent, the genetic code can be changed. This alteration in the DNA sequence may have serious repercussions, including the development of hereditary illnesses or disorders.
Therefore, a nucleotide is missing in a replicated DNA is an example of mutation i.e. Option D.

The cell cycle has a regular system of checks and balances that prevents damaged or mutated cells from proceeding to the next phase. One way an organism deals with the problems is to kill the damaged cell before it passes on the problem to its daughter cells. This is a normal process called apoptosis.
a. True
b. Fale
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.
