The correct answer is A. A law
Explanation:
In science, a law describes a phenomenon or event that always occurs under specific circumstances, and therefore it is constant. Due to this, laws are created based on multiple experiments or observations that lead to the same result. Also, a law only describes a phenomenon but does not explain why this occurs, which belongs to scientific theories.
The statement "traits are passed from parents to offspring independently of one another" by Mendel is a law because it describes a proven and constant phenomenon in genetics. Also, this is the result of the multiple experiments made by Mendel that showed the same result in terms of genetics.

Answer:
[tex] \boxed{Translation} [/tex]
Explanation:
Translation refers to the polymerisation of amino acid to form a polypeptide. The order and sequence of amino acids are defined by the sequence of bases in the mRNA.
Translation occurs at ribosome, here ribozyme (rRNA enzyme) acts as catalyst which helps in peptide bond formation. Process of translation has evolved around RNA, which shows that life began around RNA.

recessive allele?
30%
A The recessive form of the trait shows.
B Offspring display both forms of the trait.
80%
O
C Offspring display an intermediate form of the trait.
60%
D The dominant form of the trait shows.
Answer:
The correct answer is : The dominant form of the trait shows.
Explanation:
In simple dominance, the attribute related to the prevailing or dominant allele is communicated while the character related to the latent or recessive allele is persecuted or masked. For instance –
Taking a bloom where the dominant allele attribute is red shading and the recessive allele characteristic is white shading. At the point when a posterity of this bloom is created containing one prevailing or dominant allele and one passive allele, its shade would be red simply because just the predominant allele communicates its characteristic.
Thus, the right answer is: The dominant form of the trait shows.
An individual has a mutation in the gene that codes for hemoglobin. This results in sickle cell disease. Choose the correct explanation for how this mutation affects the individual's traits.
a. The error in the DNA sequence results in an error in the mRNA molecule during transcription, the error in the mRNA molecule results in an incorrect amino acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
b. The error in the mRNA sequence results in an error in the DNA molecule during transcription, the error in the DNA molecule results in an incorrect nucleic acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
c. The error in the DNA sequence results in an error in the mRNA molecule during transcription, the error in the mRNA molecule results in an incorrect nucleic acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
d. The error in the mRNA sequence results in an error in the DNA molecule during transcription, the error in the DNA molecule results in an incorrect amino acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
Answer:
a
Explanation:
The correct answer would be that the error in the DNA sequence results in an error in the mRNA molecule during transcription, the error in the mRNA molecule results in an incorrect amino acid in the hemoglobin protein which makes it non-functional. The resulting trait is sickle cell disease.
The direction of the flow of information during genetic inheritance is from DNA to mRNA and finally to protein. The information in the DNA is encoded into mRNA during transcription and the encoded information is translated into protein during the process of translation.
Hence, once there is an error in the DNA, the error is passed on to the mRNA during transcription. The consequence of this error is that the wrong amino acid is translated from the wrong codon.
Hence, the substitution of the correct amino acid by the wrong one in the hemoglobin protein results in a defect or non-functional protein. One of the phenotypic implications of this kind of error is sickle cell disease.
The correct option is a.
An error in DNA results in an error in mRNA during transcription, thereby resulting in an incorrect amino acid in the hemoglobin protein which makes it non-functional, producing sickle cell disease (Option a).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.During gene transcription, a specific fragment of DNA called 'gene' is used as template to create a complementary RNA sequence known as messenger RNA (mRNA).Subsequently, this mRNA is used as a template to create a protein in the ribosomes by a mechanism called translation. The triplets of nucleotides or 'codons' in the mRNA sequence determine the correct order of amino acids that will be added to the growing polypeptide (in this case, the hemoglobin protein).In conclusion, an error in DNA results in an error in mRNA during transcription, thereby resulting in an incorrect amino acid in the hemoglobin protein which makes it non-functional, producing sickle cell disease (Option a).

Orange coat color of cats is due to an X-linked allele (Xo) that is codominant with the allele for black (X+). When genotypes at the orange locus were determined for a sample of cats in Minneapolis and St. Paul, Minnesota, the following data were obtained:XoXo females: 11XoX+ females: 70X+X+females: 94XoY males: 36X+Y males: 112Calculate the frequency of the XO and X+ alleles (Y does not contribute) for this population.
Answer:
The X₀ frequency is 0.26
The X+ frequency is 0.74
Explanation:
Available data:
The orange coat color of cats is due to an X-linked allele (Xo)X₀ is codominant with the allele for black X+X₀X₀ 11X₀X+ 70X+X+ 94X+ Y 112X₀ Y 36To alculate the frequency of the X₀ and X+ alleles you need to sum the times it appears X₀ and the times it appears X+ alleles in the population. These sums will give you the number of alleles. As you need to calculate the frequency of these alleles, you will have to divide each number by the total number of both alleles together. This is:
X₀ = 2 x (X₀X₀) + (X₀X+) + (X₀Y) = (2 x 11) + 70 + 36 = 128X+ = 2 x (X+X+) + (XoX+) + (X+Y) = (2 x 94) +70+ 112 = 370The total number of alleles in the population is 128 + 370 = 498
To talculate the allele frequencies, f, you need to divide each allele number by the total allele number:
f (X₀) = 128/498 = 0.26
f (X+) = 370/498 = 0.74

_________10. Which of the following groups of plants carry out light dependent and light independent reactions of photosynthesis in separate cells?
A. Plants with chlorophyll C. C3 – plants
B. CAM Plants D. C4 – plants
15 point
Answer:
D. C4 plants
Explanation:
Photosynthesis is the process by which plants and other photoautotrophs synthesize carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts.
Photosynthesis occurs in two stages:
The light-dependent reactions and
The light-independent reactions, or Calvin Cycle.
Light-dependent reactions occur in the presence of sunlight. In these reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of NADPH and ATP. The light-dependent reactions take place in the thylakoid membranes in the grana within the chloroplast.
Light-independent reactions or Calvin cycle: In these reactions, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. There are three phases to the light-independent reactions: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration.
C3 plants carry out both the light-dependent and the Calvin cycle within the choroplast organelles. They carry out the Calvin cycle by producing a three-carboncompound called 3-phosphoglyceric acid, hence the name C3.
C4 plants carry out photosynthesis in a two-stage process that first produced a four-carbon intermediate compound in the chloroplast of a thin-walled mesophyll cell. Once synthesized, the plant pumps the intermediate compound into a thick-walled bundle sheath cell, where it splits the compound into carbon dioxide and a three-carbon compound. The carbon dioxide then undergoes the Calvin cycle.
CAM (crassulacean acid metabolism) plants carry out photosynthesis by absorbing sunlight energy during the day, and then using the energy to fix carbon dioxide molecules during the night.

An 81-year-old woman with RA) has been controlled with methotrexate for 18 years. Recently she experienced increased joint pain and swelling in her right knee that have affected her mobility and activity level. She walks with a cane in the community but uses a walker at home. Earlier in the week, she almost fell while walking to her car after she left the bank. The rheumatologist plans to add etanercept (Enbrel) to her drug regimen.
With what members of the health care team might you collaborate as part of her plan of care?
Answer:
It is imperative to include immunologists and dermatologists to the care team.
Explanation:
Methotrexate is an antimetabolite drug that is used to treat different diseases including, arthritis rheumatoid and psoriasis, this medicament is known to reduce cell growth and to decrease the immune system responses. Moreover, etanercept (Enbrel) is a tumor necrosis factor-inhibitor drug that also is used to treat rheumatoid arthritis and psoriasis. In addition, this drug has also been associated with the functioning of the immune system by altering inflammation responses in the body.
In consequence, it is necessary to include in the health care team both immunologists, in order to study the effect of these drugs on the immune system (like inflammatory responses, for example), and dermatologists in order to examine their effects on skin associated-conditions (like arthritis-like psoriasis).

NUCLEIC ACIDS:
Nucleic acids are one of the four biomolecules in nature. The two nucleic acids are DNA and RNA. Nucleic acids are generally involved with the storage and coding of genetic information in living cells. DNA specifically stores genetic information in the nucleus of a cell. During transcription, DNA is transcribed into mRNA (messenger RNA) in the nucleus. This means that the information in the DNA is encoded in an RNA molecule. The mRNA functions to transport the genetic information out of nucleus into the ribosome (site of protein synthesis) where translation takes place. Therefore, the role of DNA is to move information from the nucleus to the ribosomes for protein synthesis.Learn more: https://brainly.com/question/241631?referrer=searchResults

2. Fossil fuel reserves will never be depleted.
3. Fossil fuels are easily renewed.
4. Fossil fuel use does not affect the environment.
Answer:
Option 1. Fossil fuels are cheaper than alternative forms of energy.
Explanation:
Fossil fuels are made by the natural procedure in a more extended time frame, for example, anaerobic decay of the dead living resembling plants, and creatures. These plants and creature's decayed naturally to pilled up to frame coal, or common gases or raw petroleum.
By the utilization of these fuels, the stores are constantly exhausting and as it can not be recharged it will not present in the future. Non-renewable energy sources expand the greenhouse gases in condition and influence it by increasing carbon in climate. Be that as it may, these energizes are less expensive in comparison to different fuels.
Therefore, the right answer is - Fossil fuels are cheaper than alternative forms of energy.

What is the difference between causal and correlation relationships?
Explanation:
correlation relationships are between variables, however,it does not automatically mean that the change in one variable is the cause of the change in the values of the other variable. Causation indicates that one event is the result of the occurrence of the other event there is a causal relationship between the two events.
Hope this helps let me know if this was what you were asking for.
The difference between causal and correlation relationships is that
correlation relationships involves two variables in which a change in one
brings about a change in the other while a causal relationship is defined as
an explanation or reason as to why an event occurred
Causal relationship is often referred to as a correlation relationship with a
defined reason or explanation. it is also important to note that not all
correlations imply causation as reasons for some occurrences aren't always
known.
