Answer:
the oxygen should be concentrated in the alveoli
Explanation:
Diffusion: The movement of molecules from a region og higher concentration to a region of lower concentration.
So when the Oxygen is concentrated in the alveoli only then it can move towards the blood
Diffusion is a passive transport system which means it doesnt need energy in the form of atp molecules
if the molecules move from a region of lower concentration to a region of higher concentration it needs atp molecules which is energy and is called active transport system
The answer should be "HIGHER."

eukaryotic
Cytokinesis is the process in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells. It begins during anaphase and is completed at the end of telophase. Animal cells divide by a cleavage furrow. Plant cells divide by a cell plate that eventually becomes the cell wall.

Answer:
First Blank: Taiga
Second Blank: Tropical Rain forest
Third Blank: Desert
Explanation:
Process of elimination
1) we're given 4 answer choices but only three blanks. A tropical dry forest is not a thing so we know that one can't be it.
2) To be honest, I didn't know the first one off the bat, so I moved to the second blank and could easily tell it was the rain forest
3) The last blank was also obvious, being that desert climates are quite well known
4) So that left me with Taiga which I used for the first blank

Which phrase best describes translation?
A. converts mRNA into a polypeptide
B. catalyzes bonds between amino acids
c.produces RNA from DNA molecules
D. recycles tRNA molecules for reuse
Answer:
converts mRNA into a polypeptide
The phrase that best describes the process of translation is that it converts mRNA into a polypeptide. The correct option is A.
What is protein translation process?Translation is the process of converting an mRNA script into a protein. Ribosomes and tRNA are used in this process.
A ribosome decodes messenger RNA (which is produced by transcription from DNA) to produce a specific amino acid chain, or polypeptide, during translation.
The process by which a cell produces proteins using genetic information carried in messenger RNA (mRNA).
mRNA is created by replicating DNA, and the information it contains instructs the cell on how to link amino acids together to form proteins.
Decoding a messenger RNA (mRNA) into amino acids is the process of translation. Polypeptides are made up of amino acids that have been linked together.
The translation process is divided into three stages: initiation, elongation, and completion.
Thus, the correct option is A.

What type of cross did Mendel use to determine the probability of offspring when investigating two characteristics at a time
Answer:
When the offspring in Mendel's experiment were self-crossed, the F2 offspring exhibited the dominant trait or the recessive trait in a 3:1 ratio, confirming that the recessive trait had been transmitted faithfully from the original P0 parent. Reciprocal crosses generated identical F1 and F2 offspring ratios.

Can someone please give me An example of an ionic bond with a positive ion and negative ion
Answer:
NaCl
Explanation:
ionic bond is the bond results from the electro static force of attraction between oppositely charged ions in other words its the linkage formed by the transfer of one or more electron from one atom to another atom
Na gives it electron to chlroine so Na becomes positively charged and Cl becomes negatively charged and they attract each other to form ionic bond
Na is positive Cl is negative

Can an organism function with a faulty organ system?
Answer:
All of the organ systems of the body work together to maintain homeostasis of the organism. If homeostasis fails, death or disease may result.
Explanation:
Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside. All living organisms, from plants to puppies to people, must regulate their internal environment to process energy and ultimately survive
