The products of photosynthesis are also the _____ of cellular respiration.
products
outputs
reactants
wastes
The complete sentence indicates that the products of photosynthesis are also the reactants of cellular respiration (Option C).
What is photosynthesis?Photosynthesis makes reference to a specialized cellular process by which algae and also plants can generate biomass as carbohydrates (e.g. glucose simple sugars) by using as reactants carbon dioxide CO2, water, and light of the sun, which excite electrons in the chlorophyll molecules during this series of reactions.
Conversely, cellular respiration may use the glucose generated through photosynthesis and oxygen released during this process to generate ATP in aerobic conditions, thereby receiving the products of photosynthesis as reactants to develop this form of energy during this process that heterotrophic organisms (and also autotrophic aerobic organisms) require to survive.
In conclusion, the complete sentence indicates that the products of photosynthesis are also the reactants of cellular respiration (Option C).

what part of the outer ear transmits sound by vibrating
The part of the outer ear that transmits sound by vibrating is the eardrum, also known as the tympanic membrane.
What is eardrum?Eardrum is the thin, circular eardrum is the thing that divides the inner ear from the outer ear.
The eardrum vibrates as a result of sound waves entering the ear canal and changing air pressure.
The middle ear is the place at which the eardrum vibrations are amplified and transported via the ossicles to reach the inner ear i.e., the three tiny bones called the malleus, incus, and stapes.
The cochlea, which is located in the inner ear, is in charge of turning these sound vibrations into neural impulses that the brain can comprehend.
Thus, the eardrum, sometimes referred to as the tympanic membrane, is the component of the outer ear that vibrates to transfer sound.

To model how particles move as states of matter change, Jelani filled a clear box with as many marbles as the box would hold. Then he drew a picture of what the box looked like with the marbles in it.
Part A
Jelani covered the box and shook it. He could barely feel the marbles moving around the box. What state of matter does Jelani's box of marbles represent? Explain.
Answer:
It represent the solid state. In the solid state, the atoms or molecules that compound a substance have a very organized shape, as you can see in the pic, and also the solid state is the state that the particles have the minimum degree of freedom, and that explains why he barely feel the marbles moving when he shook it, it's because in the solid state the particles move less than in the liquid or gas state.

Explanation:
a random change in allele frequencies over time is known as
Answer:
Genetic drift
Explanation:
Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time. These variations in the presence of alleles are measured as changes in allele frequencies.
A random change in allele frequencies over time is known as "genetic drift." Hence, due to this, the allelic frequencies alter in a population over time.
What is genetic drift?A genetic drift changes the gene pool of a particular population. It is significant in a small population. Many factors such as migration, birth, and death affect the genetic pool. Some new genes are added to the gene pool as a result of genetic drift, while others are permanently lost. Increases in one allelic frequency replace the other allele.
In a small population of 20 animals, black skin is dominant over white. 12 are homozygous for black skin, 5 are heterozygous for black skin, and 3 are recessive and show white skin. If any natural calamities happen that destroy the white animals, then this allele will disappear from the population. After many generations, only black-skinned individuals will appear.
Hence, a random change in allele frequencies over time is called "genetic drift."

The type of energy alpha decay generates is kinetic energy, which is the last option as alpha decay is a type of radioactive decay that is generated by the nucleus of the atom.
The energy that is released in alpha decay is primarily in the form of kinetic energy, beause the alpha particle is emitted, it carries away kinetic energy due to the recoil of the remaining daughter nucleus. This kinetic energy can be calculated based on the mass difference between the parent and daughter nuclei according to the principle of conservation of energy. These alpha particles are charged in nature.

3. What virus infected Henrietta Lacks and may have caused her cervical cancer? What cellular process is affected by this virus?
4. Was there bias in the way Henrietta Lacks was treated at Johns Hopkins?
5. Put the use of HeLa cells on trial. Debate what is more important: an individual’s rights to his/her own body tissues or the medical knowledge gained by studying a patient’s tissues?
6. Should Henrietta Lacks’ family be compensated for the discoveries made using her cells?
7. Do companies or universities have the right to patent discoveries made using a patient’s tissues or genes without consulting the patient?
8. What other legal and ethical questions are raised by this book?
Answer:
1. No, tissue must not be removed without the patient's consent. Especially if it's for research purposes however fetal blood test or a biopsy.
2. It was cultured by the roller tube technique. In which the cells are lined/immobilized to the walls of the tube by serum or another medium and rotated(as in water bath) for adequate and uniform aeration.
3. The human papillomavirus 18 (HPV-18) that was later found to cause the strain of the cervical cancer she had. These viruses have two proteins E6 and E7 that turn off some of the tumor suppressors like pb53 and Rb and cause the cell lining to grow too much and cause changes in the cells that may bring cancer in some cases.
4. No. She received the standard treatment of the cervical cancer at that time, being stiched invasively with radium pouches, since the hospital was one of the few that treated black people.
5. Personally, both are important. But clearly for the betterment of the human race and people yet unborn, the medical knowledge that'll be obtained from stufying the cells and their overall benefits is more important. I completely disagree with the way the HeLa cells were obtained for I believe consent is a must since the tissues were hers to begin with and not the hospital's property. It's crucial for the patient to be notified of the pros and cons of giving the tissues and if manners of compensations can be discussed. Although malicious intents aren't wide but they're still there and it can be seen as invasion of personal privacy to some patients as well as relatives of the deceased.
6. Compensation to the Lacks family must be on the Lacks family terms. Because obviously all the discoveries made were due to the research done by the hospital still the tissues were taken without consent therefore if the Lacks family want to be compensated they must be as they want. Obviously, family can't be paid for and no amount of money that the institutions will deem fit would ever be enough unless the family decides on the amount themselves.
7. No. If the patient is alive credit must be given to the patient and the patient clearly informed on the patenting licenses and rights. And if the patient is dead then the family must be notified as well on the patenting licenses and rights. And the patenting decisions must be made only after the approval has been given by the owner of the tissues or the next of kin.
8. > Invasion of privacy was raised especially on Henrietta as well as her family.
> Ownership rights especially on th institutions that sold and benefited from the cells as well as the research and articles published without the family's knowledge.
> Right on one's body was raised on the legalization behind tissues, genes, body fluids. Things that weren't on the table for discussion are now put on the light.

c.The water will diffuse from section 1 to section 2 until the concentration of water is balanced
d.The sugar will diffuse from section 2 into section 1 until the concentration of sugar is balanced
Answer:
b or c
Explanation:
The water will move to the section with lower water concentration until it is balanced, however, I don't know which section has the sugar and which has the water. a is wrong because the membrane is semi-permeable, so water can go through, and d is wrong because it is provided the sugar cannot move across the membrane.

what came first chicken or egg
i need a explanation
Answer:
Eggs certainly came before chickens, but chicken eggs did not—you can't have one without the other. However, if we absolutely had to pick a side, based on the evolutionary evidence, we're on Team Egg.29 Mar 2018
Explanation:
Back to our original question: with amniotic eggs showing up roughly 340 million or so years ago, and the first chickens evolving at around 58 thousand years ago at the earliest, it's a safe bet to say the egg came first. Eggs were around way before chickens even existed
if a parent cell has 6 chromosomes, how many chromosomes will be in each daughter cell after mitosis and cytokinesis?
Answer:
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
Since parents cells have 6 chromosomes per cell, DNA replication will lead to 12 chromosomes and mitosis will divide this cell into two daughter cells with 6 chromosomes each.
What is mitosis?
Mitosis is a procedure where a single cell splits into two equal daughter cells (cell division). During mitosis, one cell divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn-out cells.
Thus, 12 chromosomes and mitosis will divide this cell into two daughter cells with 6 chromosomes each.
