Answer:
i think the answer should be b.
the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!
btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!

How did the Mafia gain the interest and scrutiny of the public?
Mafia gain the interest and scrutiny of the public through their unique and fearful actions.
Mafia gain the interest and scrutiny of the public by threatening people in the society as well as killing some of them. The main aim of Mafia is to earn money so they perform many actions in order to gain money from the public such as extortion, kidnapping etc.
The person who gives money to Mafia is safe but that person who refuses to pay money to Mafia will gain the punishment of death so we can say that in this way Mafia gain the interest of the public.

Examine the flow chart above depicting the job of a gene known as p53. It plays an important role during the G2 checkpoint of cell cycle regulation. In 4-6 sentences, explain why p53 is often called "The Guardian of the Genome". Is p53 an oncogene (a gene that stimulates the growth of cancer cells) or a tumor suppressor gene (a gene that turns off the growth of cancer cells)? Explain your reasoning.
The p53 protein is known as the guardian of the genome because this protein prevents errors during DNA replication. It is a tumor suppressor gene.
Tumor suppressor genesTumor suppressor genes are genes that play fundamental cellular roles and prevent cell uncontrolled growth.
A tumor suppressor gene can repair errors that occurred during DNA replication, slow down the cycle of cell division, trigger programmed cell death, etc.
The p53 acts to control cell division and cell death, thereby avoiding the emergence of cancer cells.

in plants the fertilized egg develops into a multicellular _________ within a female gametangium.
Answer:
Once fertilization has occurred, the embryo develops within the female gametophyte, and the ovule becomes the seed, complete with a food source (the gametophyte tissue) and a seed coat (the integument).

Which job description refers to the work of the mitochondrion?
Mitochondria is called as the “powerhouses of the cell,” which produce the energy necessary for the cell's survival and functioning.
What is Mitochondria?A mitochondrion is defined as an organelle found in the cells of most eukaryotes such as animals, plants and fungi which has a double membrane structure and uses aerobic respiration to generate adenosine triphosphate, which is used throughout used as a source of chemical energy in the cell.
It is known as the "powerhouse of the cell", generating the energy needed for the survival and functioning of the cell.
Through a series of chemical reactions break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.
Thus, mitochondria is called as the “powerhouses of the cell,” which produce the energy necessary for the cell's survival and functioning.

Which of the following best predicts the effect of not having ATP available to supply energy to this
process?
A. H+ ions will stop moving through the protein.
B. H+ ions will move in the other direction through the protein.
C. H+ ions will continue to move through the protein in the original direction but at a slower rate.
D. H+ ions will begin to move through the phospholipid portion of the membrane in the original direction.
H+ ions will stop moving through the protein is the effect of not having ATP
available to supply energy to this process.
ATP is the form of energy used by cells and it ensures that cells perform their
daily activities optimally. ATP is needed in a lot of metabolic reactions and
transportation of materials within cells.
When there is a lack of ATP, it means there is no energy required to
transport or move substances within a cell. This means that the H+ ions will
stop moving through the protein and is the most appropriate choice.

Having a high blood viscosity will slow down ability to climb stairs. This is
because high blood viscosity is associated with high blood pressure.
The binding of oxygen to the blood is reduced in a blood with high viscosity
as there is difficulty in the transport of blood for oxygenation due to its
higher density. This allows fro accumulation of carbon dioxide in the blood
which is harmful to body cells.
High blood viscosity will therefore reduce one's ability to climb stairs and
perform other activities.

the sequence of events that produces another generation of organisms.
The sequence of events which produces another generation of organisms is called as the Life cycle.
What is Life cycle?Life cycle is defined as the series of changes which members of a species undergo from the beginning of a given developmental stage to the beginning of the same developmental stage in a subsequent generation.
In many simple organisms including bacteria and various protists, the life cycle is completed within a single generation where an organism begins by fragmentation of an existing individual and the new organism grows to maturity which then splits into two new individuals, so the life cycle is complete.
Thus, the sequence of events which produces another generation of organisms is called as the Life cycle.

What is Transpiration ???!
[tex]\huge \bf༆ Answer ༄[/tex]
Transpiration is the the phenomenon which generally occurs in plant, In which the plant looses water in the form of water vapour through stomata.
Two main functions of transpiration ~
It causes transpirational pull that helps in transportation of water from roots to upper portions of the plantIt helps to release excess waterPlant absorb a large quantity of water from the soil by roots . this water reaches to different part of the plant by ascent of sap . the total quantity of water absorbed by plant is more than their requirement. only a fraction of this water from a vapour throw the aerial parts like (stem , leaves , buds , and , flower) of plant which constitute about 95% of total absorbed water . this process is called transpiration .
Transpiration is vital process.This process mainly occur by stomata.Water evaporates in the form of vapour from aerial parts of plant.The loss of water per unit area is more It is regulated processTypes of Transpiration -:
1 Stomatal Transpiration ;
it take place through stomata present on leaves it is also called foliar Transpiration. it constitutes about 80-95% at total Transpiration.2 Cuticular Transpiration;
it take place by cuticle present on the epidermis of plant it is constituted about 5-10% of total transpiration it rate is high in tropical climate and low desert climate.3 Lenticular Transpiration
it take place through lenticles found in Woody stem and in some fruits it constitute 0.1-1% only of total transpiration.
