Why is absolute dating more accurate than relative dating?
Answer:
Absolute dating is a technique that uses radioactive minerals present in rocks and fossils while relative dating compare the sample in terms of age difference. However, absolute dating is more accurate because it uses half-life of an element and provides dates in years.

Where does the light-dependent stage of photosynthesis occur in the plant cell?(1 point)
cytoplasm
mitochondria
chlorophyll
cell membrane
The light dependent stage of photosynthesis occurs in the chlorophyll of the plant cell.
WHAT IS LIGHT DEPENDENT PHASE OF PHOTOSYNTHESIS:Photosynthesis is the process whereby green plants obtain their food using energy from sunlight. Photosynthesis comprises of two stages namely: light dependent reaction and light independent reaction. The light dependent reaction involves the production of compounds needed in the next stage. It occurs in the chloroplast of the plant cell.Therefore, light dependent stage of photosynthesis occurs in the chlorophyll of the plant cell.

If Darwin was to be alive today, what do you think will be his observation on evolution?
Darwin would be happy that his theory of evolution is correct. Stating that biological evolution is through natural selection of inherited traits that enable a species to survive, compete and reproduce.
The haploid number is 60, so that means the diploid number is *
A) 60
B) 120
C) 30
D) 15
PLEASE HELP
Answer:

haploid(n) means a complete set of chromosomes, haploids have half number of chromosomes of a diploid(2n) organism. while diploid means two complete set of chromosomes.
If a colorblind female (XnXn) and a normal male (XNY) have a son, what are the chances he would be colorblind?
0%
100%
50%
25%
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%.

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.
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).
______ tissue moves the body and its parts.
Answer:
Musle Tissue
Explanation:
Muscle tissue helps in body & its parts movements. It is able to do so, as it consists of special contractile cells - which can contract (shorten) in response to stimulus. And, then help the movable bones to move.

Oxygen is carried through the blood by the protein hemoglobin. It is said in the article that a mutation of this protein known as
is the result of oxygen poor blood, which appears blue in veins.
A)Hemotosin
B)Methemeglobin
C)Hemolethoglobin
D)Blood Platelets
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.
The absorption process in the kidneys depends on the ___ between the medulla and the filtrate.
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.

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.
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.

What is the difference between a codon and an anticodon?
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.
Describe how natural selection is related to evolution
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.

how do stars recycle matter?
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.

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.
