This pedigree chart tracks the inheritance of a recessive trait that is not sex-linked. Based on the information in the chart, which of the following statements is true about individuals 3 and 4?
At least one is hete rozygous for the trait.
They are both hom ozygous dominant for the trait.
They are both hete rozygous for the trait.
At least one is hom ozygous for the trait.
Answers
Answer:
C. They are both heterozygous for the trait.
Explanation:
It is not possible for both parents to be hom ozygous dominant, as that would only produce hom ozygous dominant children, and from the chart they have one child that is recessive.
It is not possible for only one parent to be heter ozygous, as again, that would only produce dominant children.
Lastly, it is not possible for only one to be hom ozygous, because that again would only result in dominant children.
Pairing two heter ozygous parents would result in a 25% chance of a recessive child.
I would appreciate brainliest, if not that's ok!

Describe how natural selection is related to evolution
Answers
Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

XN XNXn XNXn
Y XnY XnY
Colorblind is a recessive trait (n) so the fraction is 2/4
If a colorblind female (XnXn) and a normal male (XNY) have a son, then the chances he would be colorblind is 50%.
Inheritance linked to the X chromosome is different from the inheritance of autonomic chromosomes because males inherit only one X chromosome.Conversely, females inherit two X chromosomes, thereby resembling mendelian autonomic inheritance.In the Punnet square:Xn Xn
XN XNXn XNXn
Y XnY XnY
In conclusion, if a colorblind female (XnXn) and a normal male (XNY) have a son, then the chances he would be colorblind is 50%.

Answer:
genes are the basic sequence of DNA that controls the traits of an organisms.
Explanation:
genes have nucleotide sequences. these sequences are involved in transmission of characters from one generation to other. if their is an error occur in this sequence the new offspring will b dissimilar from parent in this secific character which chnaged.
central dogma is the basic process through which genes are controlling the traits. first step is transcriotion through which DNA or gene is transcribed into mRNA sequence. then the second step is translation in which mRNA is translated into protein. in this way by making proteins genes control the traits or functiong of a body.

A person drives her own personal vehicle to work two days of the week. Her commute to and from work is 42 miles a day, and her car averages 28 miles per gallon? How much gasoline
is the person conserving a day if she takes the train instead? (5 points)
O 1.5 gallons per day
O 3.0 gallons per day
O 4.5 gallons per day
0 5.5 gallons per day
Answers
Answer:
The correct answer is - 1.5 gallons per day.
Explanation:
Given:
Distance traveled by a person: 42 miles a day
Average of gasoline used - 28 miles/gallon
Solution:
Daily consumption = distance traveled/ average consumption
Placing the value in the formula
= 42/28
= 1.5
Thus, the correct answer is - 1.5 gallons per day conserved.

The absorption process in the kidneys depends on the ___ between the medulla and the filtrate.
Answers
Answer:
try b and tell me if i am wrong please
Explanation:
The absorption process in the kidneys depends on the between the medulla and the filtrate in the cortex as the cortex is found in between the medulla and filtrate.
The cortex presents an area for arterioles and venules from the renal artery and vein, in addition to the glomerular capillaries, to perfuse the nephrons of the kidney. Erythropoietin, a hormone important for the synthesis of the latest crimson blood cells, is likewise produced withinside the renal cortex. Its predominant feature is to reabsorb water and sodium chloride from the filtrate.
What is the function of coetex ?This conserves water for the organism, generating exceedingly focused urine: The inner-maximum location of the kidney is organized into pyramid-like structures, that include the majority of the nephron structure. renal cortex: The outer location of the kidney, among the renal tablet and the renal medulla, includes an area that consists of blood vessels that hook up with the nephrons.
Thus it is clear that the absorption process in the kidneys depends on the cortex that is in between the medulla and the filtrate.

Suppose that a cytoplasmic protein (a protein that will function in the cytoplasm inside of the cell) is synthesized by a particular cell type. Describe the route that this protein will take from the moment its synthesis starts in the nucleus until it makes it into the cytoplasm.
Answers
Answer:
A specific gene that contains the information to encode the target protein is transcribed as a primary transcript (pre-mRNA). Subsequently, the pre-mRNA is processed to form a mature mRNA. Finally, this mRNA then moves through a nuclear pore from the nucleus to the cytoplasm where proteins are translated in the ribosomes
Explanation:
The cell nucleus contains the majority of the cell's genetic material localized on linear molecules called chromosomes. During transcription, genes (specific chromosome segments) are used to synthesize primary transcripts (pre-mRNAs) which are then proceeded to produce mature messenger RNAs (mRNAs). RNA processing involves the removal of non-coding intron regions and the joining of coding exon regions (RNA splicing) in order to form a mature mRNA sequence. Subsequently, the mature mRNA leaves the nucleus through the nuclear pores of the nuclear membrane and travels to the ribosomes where is decoded (translated) to produce a specific polypeptide chain (i.e., a protein). Within the ribosome, the mRNA strand binds to multiple transfer ribonucleic acids (tRNAs) via complementary and consecutive three-nucleotide mRNA sequences called triplets or codons, and tRNAs deliver specific amino acids that are consecutively added to the polypeptide chain.

According to the National Institute of Health, atrial fibrillation (A-F) occurs if rapid, disorganized electrical signals causing the heart's two upper chambers, called the atria, to fibrillate. The term "fibrillate" means to contract very fast and irregularly. In A-F, blood pools in the atria. It isn't pumped completely into the heart's two lower chambers, called the ventricles. As a result, the heart's upper and lower chambers don't work together as they should. Based on the passage above, how will atrial fibrillation affect blood pressure?
A. It will lower blood pressure because less blood is pumped per beat.
B. It will increase blood pressure because the heart is contracting faster.
C. It will increase blood pressure because the atria fill fully with blood.
D. It will lower blood pressure because blood volume drops in the atria.
Answers
Answer:
A. It will lower blood pressure because less blood is pumped per beat.
Explanation:
I thought B might be a potential answer, but since the atria are not filling properly and heart rate is increased, it would make sense that blood pressure drops (effect of faster heart contraction is negated by the drop in blood volume in the atria).
