Answer:
A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.
Explanation:
In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.
In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.
For the other options:
Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.Answer:

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose
A) atp is used
B) pyruvic acid is produced
C) oxygen is produced
D) nadph is made
Answer:
D)NADPH is made
A)ATP is used
Explanation:
Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]
The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:
Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.
First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).
Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis). That is, the chemical energy of ATP and the reducing potential of NADPH, both produced with the use of light energy, keep the Calvin cycle running. Conversely, the Calvin cycle regenerates ADP and NADP^+

TRUE FALSE: Organisms can CHOOSE to have a mutation
Answer:
False
Explanation:
Organisms themselves cannot choose to have a mutation. However, it can be artificially done in labs.
Organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.
What is the significance of the mutation and its consequences?mutation has many consequences, such as the Mutations can cause developmental disorders such as birth defects, mutations can increase an individual's risk of developing genetic disorders, and they also reduce the genetic diversity of a population. Mutation leads to the loss of function in an essential gene, resulting in a decrease in the organism's fitness in the ecosystem.
Hence, organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.

There are _____ levels of intellectual disabilities on the modern continuum.
A.
five
B.
four
C.
three
D.
two
Answer:
B) Four
Explanation:
There are four levels of intellectual disabilities on the modern continuum. The correct option is B.
What are intellectual disabilities?A person is said to have an intellectual disability when their capacity to learn at a typical rate and function in daily life is restricted. The severity of intellectual disability in children varies widely.
Despite the fact that a precise full-scale IQ test result is no longer necessary for diagnosis, standardised testing is nevertheless used to help make the diagnosis.
A full-scale IQ score of between 70 and 75 denotes a considerable intellectual functioning restriction.
Each person's level of difficulty with learning and processing information, difficulties with abstract cognition, and issues with social interaction are all common aspects of intellectual impairments.
On the contemporary continuum, there are four stages of intellectual disability.
Thus, the correct option is B.

What kind of bonds hold the phosphate groups together in ATP and ADP? Exxplain please
Answer:
These phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.
Explanation:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).
Help please!!!!!!!!!!!!!!!!
Answer:
D is NOT true about plants.
Use the diagram to answer the question. Between which parts of the molecule must the bonds be broken to form an ADP molecule?
The parts of the molecule whose bond must be broken to form an ADP molecule would be between C and D. Thus, option A would be correct.
The image is an illustration of the structure of ATP, Adenosine Triphosphate. The hydrolysis of the terminal phosphoanhydridic bond in ATP yields energy for metabolic reactions in biological systems and ADP (Adenosine Diphosphate) is formed as a result.
In this case, the terminal phosphoanhydridic is D. Thus, the bond between D and C must be broken for ADP to result.
