What happen when a star fish is put in a lake

Biology

ycow [4]3 years ago

Because of osmosis it would die, not just in a lake but any fresh water.
If you put a freshwater fish in salt water the salt would draw the mouisture out of its body making it die.
Same thing happens if you put an ocean water fish in freshwater except the salt within its body would draw to much fresh water in, and its body salt would fall out into the freshwater and later die.

This all has to do with PH and the PH balance so you can read more about that to understand.

They might die because they need salt water to survive.

OLEGan [10]
C6H12O6, or sugar, is organic. It is created out of one glucose unit and one fructose unit. It is a carbohydrate, which includes starch, sugar, glucose, and fructose, which means it is a natural product. Last but not least, since it contains carbon, hydrogen, and oxygen, it is organic.

Squamous epithelium, sperm cells, smooth muscle, or human red blood cells:
polet [3.4K]

Answer:

1. sperm cells: cell has a flagellum for movement

2. smooth muscle: cells have an elongated shape (tapered at each end)

3. Squamous epithelium: cells are close together

4. Human red blood cells: cells are circular

5. Squamous epithelium cells are thin and flat, with irregular borders

6. Human red blood cells: cells are anucleate (without a nucleus)

7. smooth muscle: longest cell

Explanation:

  • <em>Sperm cells</em>: Active and morphologically specialized cells. They characterize as having an elliptic head mostly occupied by the nucleus, and a tail of about 55 micrometers that moves impulsed by a motor dynein protein that uses ATP energy.
  • Smooth muscle cells: Fusiform cells. Long and tapered at the extremes. Located in organs and viscera, and in vessel walls, where involuntary maintained slow contractions are needed. Although they are the longest cells, their length depends on the organ where they are located. They might reach up to 500 microns.
  • Squamous epithelium cells: The wide and length of the cells supere their height. Some of them suffer a process of keratinization from being exposed to dehydration and touch.  
  • Red blood cells: Red blood cells or erythrocytes are biconcave disks-shaped, with no nucleus, and very small. These are flexible cells that might move along in the smallest capillaries. Hemoglobin provides the typical red color. The red blood cell size and number vary among species.

The test results below indicate the presence of which nutrient? four test tubes A. monosaccharide B. polysaccharide C. protein D
mel-nik [20]

Answer:

See below

Explanation:

Q1. incomplete information given

Q2. Protein will be present so <u>test tube C.</u> Beef is a rich source of protein. Hence, the Biuret test will be relevant in this case since that is specific to detecting proteins.

Q3. Orange juice has ample amount of simple sugars (such as fructose, glucose), which are monosaccharides. So option A. Benedict test is required here.

Q4. Incomplete information provided

Q5. You need a certain kind of food that is rich in protein and simultaneously lacks fats. Here, skimmed milk is relevant - fat has been removed from the milk although protein is still present.

Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducin
Phoenix [80]

Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducing an immune response and then has a subsequent exposure to the same antigen. The sensitization phase is characterized by <u>Induction of a CD4 T cell type II immune response</u>.

The process by which your body becomes sensitive to a particular substance is called sensitization. When your immune system becomes sensitized to an allergen, you can develop certain symptoms.

Antigens that can induce an allergic response are called allergens, and they are often derived from non-infectious or non-microbial sources.
