is the result of oxygen poor blood, which appears blue in veins.
A)Hemotosin
B)Methemeglobin
C)Hemolethoglobin
D)Blood Platelets
Answers
Answer:
The correct answer is - B) Methemeglobin.
Explanation:
Methemeglobin is a blood disorder due to the mutation in the hemoglobin which is known as the result of oxygen-less blood. In this disorder, the tissue did not get enough oxygen and appeared to be purple, or blue.
In this mutated form of hemoglobin iron atoms present in ferric instead of the ferrous state and therefore not able to bind with oxygen. It appears blue in veins and tissues look blue or purple.
how do stars recycle matter?
Answers
Answer:
Stars forge heavy elements and return their gas to space. This material enriches gas clouds from which new stars are formed, and the cycle continues. Each generation of stars is made in part from the ashes of previous generations. The material of stars is recycled over billions of years.
Explanation:
The material of stars is recycled over billions of years. Interstellar gas clouds collapse to make stars. Stars forge heavy elements and return their gas to space. This material enriches gas clouds from which new stars are formed, and the cycle continues. Each generation of stars is made in part from the ashes of previous generations.

Hope this is right
Answer:
Stars forge heavy elements and return their gas to space. This material enriches gas clouds from which new stars are formed, and the cycle continues. Each generation of stars is made in part from the ashes of previous generations. The material of stars is recycled over billions of years.
Furthermore, Rubin and colleagues find evidence that this new fuel could come in the form of recycled gas once ejected by the galaxy, pushed out by massive supernovae events or by the light pressure of massive newborn stars, but which does not leave the gravitational clutches of the galaxy completely.
What is the difference between a codon and an anticodon?
Answers
Answer: A codon is the triplet sequence in the messenger RNA (mRNA) transcript which specifies a corresponding amino acid (or a start or stop command). An anticodon is the corresponding triplet sequence on the transfer RNA (tRNA) which brings in the specific amino acid to the ribosome during translation.
P2: How do genes determine an individual's traits? (click here to learn how to correctly check the box) Correctly choose one: Genes directly lead to traits. I Genes are random and don't lead to traits. Genes give organisms the ability to change their traits Genes are instructions for making protein molecules and protein molecules determine traits.
Answers
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.

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.

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.

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).

Answers
Answer:
50%
Explanation:
Make a punnet square
Xn Xn
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%.

Explanation: For a recessive trait to show up, there cannot be a dominant trait in the genotype or else the dominant trait will appear. This means that the only way for a recessive trait to show up is for the genotype to be “ee”
In order for a recessive trait to show up, the organism needs to have an "ee" genotype Option C is correct. This is further explained below.
What is Genotype?Generally, The word "genotype" is simply defined as an organism's genetic composition in a general manner of speaking.
