Answer:
When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.
The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.
There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.
Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water

*Please Help* Which of the following organisms would you expect to be most abundant in the tallgrass prairie ecosystem?
A. Grasses and flowering plants
B. White-tailed deer and cottontail rabbits
C. Bobcats and Coyotes
D. Harriers and kestrels
Answer:
A
Explanation:
Prairies are unique ecosystems dominated by grasses and other non-woody plants called forbes. ... A prairie ecosystem includes all the living components-- plants and animals--and all the nonliving components-- sun, water, fire, soil, and--nutrients.
The tallgrass prairie is a north American ecosystem and is famous for large grazing animals. The ecosystem consists of forests, grasslands, and savanna.
The tallgrass is capable of supporting significant species. Parts of the region have about top reptiles, birds butterflies, and trees. Many of the species are found in the understory layer. This biome depends on the barriers files. Tallgrass is home to a diverse number of species such as cattle, bison, harriers, coyotes, and bobcats.Hene the ecosystem of the tallgrass is dominated by the organisms like the Bobcats and Coyotes. This option C is correct.

Use scientific reasoning to explain why, in general, it makes sense that the lion population is taking longer to recover than the herbivore populations.
To scientifically answer the question using scientific reasoning, explaining generally why it makes sense that the lion population is taking longer to recover than the herbivore populations is that;
The herbivore populations have enough food in the ecosystem,this food is in the form of flora,and this food they get keep their energy flowing and also has a way of ensuring their high recovery rates.
Then looking at the lion population,on the contrary,they have to depend on feeding on smaller animals this is because the larger animals reproduce at a smaller pace, and lions with a smaller prey,lions don't get enough and adequate food/nutrition for themselves and also for their pride of lions,this ascertains the fact that lion population take a longer time to recover than it's counterparts which is the herbivores.

First drag pink labels to pink targets to identify the digestive organs. then drag blue labels to blue targets to identify the source of each digestive enzyme or fluid.
Answer:
According to the diagram, the digestive organs on the pink targets includes:
a.) Liver, c) esophagus, d) gall bladder, e)Stomach, I) Small intestine j) Pancreas
The source of each digestive enzyme or fluid on the blue targets includes: b) bile, f) pepsin, g) Intestinal enzymes, h) Pancreatic juice.
Explanation:
The digestive system is the collective name used to describe the alimentary canal, accessory organs and a variety of digestive processes that takes place at different level in the canal to prepare food eaten for absorption.
Accessory organs of digestion generate various secretions which are poured into the tract to aid in the digestion of the food taken. They include: salivary gland, pancreas (secrets pancreatic juice), liver ( secrets bile), gall bladder ( stores bile).
ABC is an isosceles triangle with AB = BC. If AB = 3x + 41, BC =
8x – 54, and AC = 12x – 103, find x and the measure of each side.
Answer:
x = 90
Explanation:
Ab = 3x + 41, BC = 8x - 54, and AC = 12x - 103, find x and the measure of each side.
-----
AC = AB + BC
------
12x-103 = 3x+41 + 8x-54
---------------------
12x-103 = 11x - 13
x = 103-13
x = 90

Choose 1 answer: Choose 1 answer: (Choice A) A It is a catabolic reaction. (Choice B) B It is a photosynthetic reaction. (Choice C) C It is an endergonic reaction. (Choice D) D It is an anabolic reaction.
Answer:
The correct answer is - (Choice A) A It is a catabolic reaction.
Explanation:
The catabolic reaction is a reaction that involves the sepration of larger molecules into smaller molecules and releases the energy stored in the chemical bond.
This metabolic reaction breaks the larger molecules into smaller and simple molecules for example in cellular respiration glucose molecule is broken down into water and carbon dioxide and releases energy in the form of ATP.
Answer: D- It is an anabolic reaction.
Explanation: This reaction is anabolic, since it consumes energy to build a more complex molecule from smaller ones.
Which of the following is not a cause of a tsunami?
Question 5 options:
Earthquake
Volcanoes
The moon
Landslides
The moon moon moon moon
Explanation:
moon
A Tsunami is a huge tide or a series of killer waves that have the ability to move a large quantity of water.
The Tsunamis are a product of earthquakes, landslides and volcanic eruptions as they displace a large amount of water from the land surface. Being seismic waves these Tsunamis are able to destroy property and cause havoc on life forms. The moon comparatively is located at a distance of 384,400 km and thus causes high and low tides. The moon does not possess a large gravity potential to cause a Tsunami on earth.Hence the correct option is C.

What is an amniote, and which animals on this tree are amniotes?
Amniotes are these animals such as reptiles and birds whose embryos have a membrane that surrounds them, as a protection, called amnion.
What are amniotes?They are an extensive group of animals such as reptiles, birds or mammals that have amnions during their embryonic phase.
The amnion is a fetal membrane that lines the chorion and delimits the amniotic cavity, that is, it is an internal membrane or closed sac that surrounds and protects the embryo.
Therefore, we can conclude that amniotes are these animals such as reptiles and birds whose embryos have a membrane that surrounds them, as a protection, called amnion.
