hypertonic is when blood cells shrivel under hot temperatures
isotonic is equilibrium between concentration of blood and salt
hypotonic is less concentration on outside compared to inside
Answer:
When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. ... If placed in a hypotonic solution, a red blood cell will bloat up and may explode, while in a hypertonic solution, it will shrivel—making the cytoplasm dense and its contents concentrated—and may die.
water freely enters and leaves cells through channels formed by membrane proteins by

Why do you think plants and animals have different types of cells?
Answer:
cause plants do not move from there places and need to make there own food so he can survive.. that is why they need a cell with all necessary and animals can hunt or eat plants which means he just need the cells to produce energy and movements
Explanation:
Plants and animals have different types of cells because they possess different characteristics, modes of nutrition, adaptation, metabolic activities, etc.
What are Plant cells?Plant cells may be defined as the type of eukaryotic cell that has a well-defined nucleus and other membrane-bound cell organelles. These cells are the basic unit of life in organisms of the kingdom Plantae.
Animal cells are also of eukaryotic nature but both shares a huge difference in the composition and manufacturing of cells. Plants have to synthesize their own food with the help of sunlight so they possess chloroplast while animal cells are of the heterotrophic mode of nutrition where they derive their food from plants and their products.
Plants are typically immobile in nature so they have required some sorts of cells that provide them stability in their survival. While animals need some motility cells like bones and other tissues that provide the movement.
Therefore, on the basis of structural dissimilarities, mode of nutrition, adaptation, metabolic activities, etc. plants, and animals have different types of cells.

Describe Genotypic Species Concept
Answer:
Genotype is the collection of genes responsible for the various genetic traits of a given organism. Genotype refers specifically to the genes, not the traits; that is, the raw information in an organism's DNA. Genotype is determined by the makeup of alleles, pairs of genes responsible for particular traits.

which part of the carbon cycle breaks down carbohydrates into carbon dioxide and water
Resipration
Ersion
Decomposition
Answer:
Respiration
Explanation:
Respiration is a component of the carbon cycle which breaks down carbohydrates into carbon dioxide and water.
Respiration is an aerobic process that takes place in the presence of oxygen.
It is a catabolic process in which energy rich compounds are broken down. In this process, oxygen combines with carbohydrates to produce carbon dioxide and water with the release of energy. Carbohydrates is rich and embedded with energy.Cellular respiration is the process that releases energy for living organisms.

Humans are able to move their shoulder 360 degrees. What morphological features aid in this degree of motion (i.e. which bones)? Examine the bat wing below. Is there the same degree of motion? Explain why or why not.
Answer:
This question is incomplete because of the absence of bat diagram discussed in the question
Explanation:
Humans body contains several joints that allows from movement of bones at some junctions called the "joints". Joints are points where two bones meet. Examples of the human joints include the ball and socket joints, hinge joint, pivot joint, gliding joint, saddle joint. The type of joint in the human shoulder that allows for 360 degrees rotation is the ball and socket joint. It involves a bone that has a round head like that of a "ball" which can fit into an open cup-like shape called the "socket", hence the reason for the name. This joint allows for movement in all directions.
The bat wing does not move at the same degrees (360°) as it does not move in all directions - the wing has an up and down movement which is more of a 180° movement and not a 360° movement.

Explain how soil formation is helped by biotic components through primary succession.
Answer:
Please find the explanation below
Explanation:
Primary succession is a type of succession that occurs in an area with no previous community. It usually contains bare rocks, which are grown upon by certain living organisms (biotic components) called PIONEER SPECIES. These organisms, which include lichens and mosses, colonize the bare rocks and contribute to the formation of soil by the gradual disintegration of the rock particles.
These biotic components (living organism) also help to enrich the soil being formed as they add organic matter, which serve as nutrients, when they die and decompose. The actions of these living organisms on the formation of soil enables other organisms to easily colonize the area.

2. Humans clear land for farming: Secondary succession.
3. A lake dries up, forming a marsh: Secondary succession.
4. A wind storm builds new sand dunes: primary succession.
What are main differences between primary and secondary succession?
Primary succession happens in a region without any initial verdure. Secondary succession occurs in a region with initial verdure. Primary succession is started either due to a biological factor or an outer agent. An external factor initiates secondary succession.
