What are macromolecules that contain carbon, hydrogen, oxygen, and nitrogen, needed by the body for growth and repair?
Answer:
protein
Explanation:
A macromolecule that contains carbon, hydrogen, oxygen, and nitrogen, which is used by the body for growth and repair. Protein Synthesis.
This is a two-part process that ends in the assembly of proteins at the ribosomes within cells.
If a cell that is about to divide has 22 chromosomes how many chromatids does it have? How many centromeres does it have?
44 chromatids 2 centromeres, If a cell that is about to divide has 22 chromosomes.
What are chromosomes?In the synthesis phase, the number of chromatids doubles while the number of chromosomes remains constant. Although the number of chromatids is unaffected, anaphase doubles the number of chromosomes.
Depending on whether or not the DNA has replicated and when the sister chromatids split, the chromosome changes during the cell cycle.
Meiosis I and Meiosis II are the two division cycles that occur during a meiotic cell division. Since the genetic material duplicates during the S phase of meiosis I, there will be 2n chromosomes during metaphase I.
Therefore, if a cell that is about to divide has 22 chromosomes it have 44 chromatids and 2 centromeres.

A scientist wants to determine the age of a rock. The rock contains an index fossil and an ancient relative of a living organism. Which is more useful for dating the rock, and why?
Answer: Ancient Relative of a living organism
Explanation: Ancient Relative because by using the index fossil, you are also using the law of superposition. This law does not give you an accurate/specific date but instead the order they are in (i.e me saying i am older than my siblings compared to me saying i am 2 years older than them). By using an ancient relative of a living thing then we can see its phylogenic tree and measure around how old it is. Fossils also hold carbon and chemicals in there bones which allows us to use carbon dating. Carbon dating is an accurate way of measuring age.

Check the statements below that provide evidence for the endosymbiosis theory
The DNA in the nucleus and mitochondria are the same.
This is not exactly true, although they are similar. This is not a correct option.
The following three are correct options:
Mitochondria and chloroplasts grow independently from the cell.
This is true, and supports the idea that they previously existed as their own organisms.
Prokaryotic cells, mitochondria, and chloroplasts are all the same size.
All three organisms/organelles are roughly the same size, which supports the idea that chloroplasts and mitochondria are descendants or prokaryotes.
Mitochondria and chloroplasts contain their own ribosomes.This is true as well.
Which neurons are responsible for
passing the collected information to
other neurons or can respond on their
own?
A. interneurons
B. motor neurons
C. sensory neurons
D. glial neurons
Answer:
A. interneurons
Explanation:
which neurons receive a signal first? (information about the environment like heat or pain)
Answer:
Dendrites. The first two neuronal functions, receiving and processing incoming information, generally take place in the dendrites and cell body.

what is the main product or purpose of photosynthesis?
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Hope that helps. x
When autotrophs produce more organic matter than they use in respiration tehre is anet increase in organic matter. That is called
A. Anaerobic repiration.
B. Diffussion.
C. Primary production.
D. Osmoregulation.
Answer: Primary Production
Explanation:
A net increase in organic matter seen when autotrophs produce more organic matter than they use for respiration, The hint was autotroph, an autotroph is always a primary producer, so there for it would be primary production.
