Look at your model and think about the relationship between oxygen and carbon dioxide in the sealed jar. Which of these statements is true?
Plants release only carbon dioxide during photosynthesis.
Plants use oxygen during photosynthesis.
Plants and animals use oxygen during respiration.
Plants and animals release oxygen during respiration.
Answer:
Plants use oxygen during photosynthsis.
Explanation:
Oxygen and carbon dioxide in the sealed jar relationship between oxygen and carbon dioxide is that Plants and animals use oxygen in respiration, hence option c is correct.
What is respiration?Water and carbon dioxide are converted into oxygen and glucose in photosynthesis and plant uses glucose and releases oxygen as a byproduct.
Oxygen and glucose are converted to water and carbon dioxide in cellular respiration. By-products of the process include carbon dioxide, water, and ATP, which are turned into energy.
Carbon is taken out of the atmosphere by photosynthesis and put back in by cellular respiration.
Therefore oxygen and carbon dioxide have a relationship in respiration, hence option c is correct.

Explanation:
Sometimes after an intense exercise routine, an individual will have sore muscles 1 to 2 days following the exercise; this is called delayed onset muscle soreness. Although not completely understood, it is believed that one cause of this is damage that occurs to the Z disks and contractile filaments in the muscles. When the body attempts to repair this damage, an inflammatory response occurs that causes soreness a couple of days after the exercise has taken place. Which of these situations would likely lead to less delayed onset muscle soreness in an individual?
a. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be stronger
b. a mutation that would reduce the amount of lactic acid buildup in muscle tissue
c. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be weaker
d. a mutation that weakens the calcium binding ability of troponin
Answer:
The correct answer is option A. a mutation in the Z-disk protein that caused the attachment of the Z disk to the titin protein to be stronger
Explanation:
As delayed onset muscle soreness is thought to be led by the inflammatory response of the body in order to repair damage to the Z disks and contractile filaments in muscles, due to the intense exercise.
Mutation in the Z-disk protein would strengthen the connection between Z disks and contractile filaments as it is logical that this mutation could withstand more pressure or intense exercise before damage occurs to these tissues.

The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet. It was proposed by Alfred Wegener.

(ANSWER NEED RIGHT AWAY!! PLS) A classmate claims that an apple and cupcake, both about the same size, give you the same amount of energy. Do you agree or disagree with this
statement? Explain.
Answer:
No, just because something is the same size doesn't mean it will have the same amount of energy. One thing can have more positive electrons and make it have more energy than the other.
If bacteria do not contain a nucleus will bacteria still have DNA?
Of course not the DNA is found in two basic forms: a chromosomal loop and ring-like plasmids. The chromosomal loop is literally a looping string of DNA. Since there is no true nucleus in a prokaryotic cell, the DNA is suspended in cytoplasm, or the fluid filling the cell.

Hormones are proteins that regulate many functions in the body, such as growth and cell differentiation. Which of the following does NOT describe a function of proteins in living organisms?
Answer Options:
Proteins store energy long term, provide lubrication, and insulate the body Proteins in the form of enzymes catalyze chemical reactions Proteins provide structures in the body, such as hair and muscles Proteins in the cell membrane help transport substances into and out of cellsAnswer:
Proteins store energy long term, provide lubrication, and insulate the bodyExplanation:
Proteins store energy long term, provide lubrication, and insulate the body - this is false, this describes the role of fats. Proteins in the form of enzymes catalyze chemical reactions - this is true, enzymes are an important class of proteins in the bodyProteins provide structures in the body, such as hair and muscles - this is true, for example our hair is made of a protein called keratin Proteins in the cell membrane help transport substances into and out of cells - this is true, proteins form important pumps and channels in the cell membranePlz ASAP What is the male sex cell that results from meiosis?

What are the roles of different organelles in a cell?
Answer:
Functions of different cell organelles:
Nucleus: contains all the genetic material, acts as information center and tells all the organelles what to do, RNA transcription.
Mitochondria: generates energy through respiration
Endoplasmic recticulum (rough): transport and storage of material; (smooth ER): creation of lipids and fats
Ribosome: protein creation by RNA translation
Golgi apparatus: responsible for synthesis, packing and processing of proteins
Chloroplast: responsible for glucose creation (by photosynthesis)
Cytoplasm: is region where all chemical reactions take place and is the jelly like fluid that holds all the organelles in place inside of the cell
lysosome: responsible for breakdown of larger molecules
Flagellum (or flagella): tail like organelle, assists motion
Vacuole: helps in maintenance of homeostasis and stores waste products or other materials like water / food
cell membrane: separates cell from the rest of the environment and controls what comes in and out of the cell
cytoskeleton: supports cell structure
There are a number of other organelles as well but i just named some of the common ones.

Answer:
The correct answer is they both have rings around them
Explanation:
Saturn and Uranus are both planets in our solar system; indeed Saturn is the sixth planet while Uranus is the seventh planet. Besides this, Saturn and Uranus are giant planets, this means they are composed of gas or similar materials and they are massive. Moreover, as giant planets these two planets have a ring system, which means around them, there are dust and other particles that orbit the planet and form rings; although, in the case of Saturn these are massive and more visible. According to this, Saturn and Uranus are alike because they both have rings around them.
Answer:
They both have rings around them.
Explanation:
The only 4 planets in our solar system that are gas giants have rings.
