- If a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be?
Answer:
If 0.9% NaCl were isotonic to a cell then anything greater than 0.9% would be hypertonic. A hypertonic solution is one which has a greater concentration of dissolved solutes while an isotonic one has a similar concentration of solutes.
Explanation:
If a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.
What is a Hypertonic solution?A hypertonic solution may be defined as a type of solution that significantly has lower osmotic pressure than another solution to which it is compared. If the surrounding solution has a higher solute concentration compared to inside the cell, it represents a hypertonic solution.
According to the context of this question, if a 0.9 % salt solution is isotonic to an animal cell, then anything greater than 0.9% would be hypertonic. So, all the options except for 1.0% are lesser than or equal to 0.9%.
Therefore, if a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.

fill in the venn diagram below with the following terms:exocytosis,diffusion,endocytosis,osmosis
Answer:
there more tissues or more organs in your body explain your reasoning
Explanation:
Each organ is made up of several different types of tissue. Therefore, for every organ in the body, there are many more tissues.
Answer: Venn diagram of exocytosis , diffusion , endocytosis , osmosis is
described below.
Explanation:
Exocytosis: refers to the process by which the contents of a cell are released to the exterior environment through fusion of the vacuole membrane with the cell membrane.
Endocytosis: refers to the process in which cells take the material from outside the cell by taking in the vesicle. These materials serve as nutrients and pathogens which help cell to fight against foreign diseases.
The common thing these two process have among them is
FlagellaPlasma MembraneCell divisionCytoplasmRibosomes chromosomesDiffusion: It is the process of movement of molecules from through a
semipermeable membrane from the region of higher concentration to lower concentration.
Osmosis: The movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's fractionally permeable membrane.
The common thing these two process have among them is that equalizes the concentration of two solutions in mixture

what is excretion meaning
Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life.

What is a cell?Cells are the fundamental cornerstones of all life. Gazillions of cells make up the human body.
They support the body's framework, absorb nutrients from food, convert those calories into energy, and perform specialized functions.
The cell, first discovered by Robert Hooke in 1665, has a rich and interesting history that has led to many of today's scientific advances.
Cell theory is a biological theory first proposed in the mid-nineteenth century that states that living organisms are made up of cells, that cells are the basic structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.
Thus, the correct option is B.

The respiratory center is medulla oblongata. It is involved in minute to minute control breathing.
What parts are involved in the brain stem ?
Brain stem is made up of pons and the medulla oblongata.
The apneustic and the pnuemotaxic centers of pons work together to just control rate of the breathing. In that the medulla just sends the signals to muscles that just initiate the inspiration and the expiration and just controls the nonrespiratory in the air movement of the reflexes like coughing and sneezing.
The cerebellum is well known to just be the part of neuronal circuitry that is just activated in the respiratory challenges that are such as the hunger for the air but are not been made to be involved in control of the spontaneous and the unobstructed breathing .

The descriptions below explain two ways that water is used by plants on a sunny day.
I. In a process called transpiration, some liquid water in leaves changes to water vapor. The water vapor is released into the air through tiny pores in the leaves. This allows more liquid water from the soil to be pulled up the roots and stem to replace water lost from the leaves.
II. Plants use some of this water in leaves in a process called photosynthesis. During photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen, and glucose.
Based on the above description of transpiration and photosynthesis, which type of change happens to water during each process?
A. In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.
B. In transpiration, because some of its properties change, water undergoes a chemical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a physical change.
C. In transpiration, because its physical properties change, water undergoes a physical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a chemical change.
D. In transpiration, because its chemical properties change, water undergoes a chemical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a physical change.
