Answer: They all survive in any environment.

Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.

I'll explain why the others aren't correct.

Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.

Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.

Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.

Let me know if you have any questions.

Considering that a hydrophilic stain was used to stain the skin, explain why the fat vacuoles in adipocytes are white (Hint: Rem

vazorg [7]

Answer:

The hydrophilic nature of the stain explains that these molecules are polar and charge molecules. therefore, attracts the water molecule but due to their polar nature, it will avoid lipid or fat molecules.

Adipocytes are the cells that are made up of fat or lipids that are hydrophobic due to their non-polar nature and due to this fact, these hydrophilic stains will not be able to stain adipocytes and will not be colored by the stain.

A corn plant known to be heterozygous at three loci is testcrossed. The progeny phenotypes and numbers are as follows:+ + + 455a

astraxan [27]

Answer:

The progeny phenotypes and numbers are as follows:

+ + + 455-------- parental

a b c 470-------- parental

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

+ b + 460---------- parental

a + c 475----------- parental

Total 2,000

+ + + 455-------- parental

a b c 470-------- parental

+ b + 460---------- parental

a + c 475----------- parental

It is two point testcross

So the parental ++ (455+460); ac (470+475)------------------++/ac

Gene order is ------------- ++/ac

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

sum of recombinants--------------140

Frequency of recombintion= recombinants/total x100

Map distances between a-c = (140/2000) x 100 = 7 mu

a------------------7 mu -----------------c

Mammals do not produce digestive enzyme B. However, sheep and cattle are two types of mammals that contain microorganisms in the

Lady bird [3.3K]

Answer:

The correct option is this: A specific enzyme removes the hydrogen from the monosaccharide and the hydroxide from the polysaccharide, creating a bond between the two and creating a water molecule.

Explanation:

The process by which a monosaccharide molecule is added to an existing polysaccharide in biological systems is called CONDENSATION POLYMERIZATION.

During the process of condensation, an hydrogen atom and an hydroxide molecule from the reactants come together to form a water molecule; this leads to the formation of covalent bond between the reactants.

Condensation reaction is used in living organisms to produce complex macro molecules such as carbohydrates, proteins and lipids, which are needed by the body for health growth.

Remember, condensation reaction always results in loss of water molecules and formation of more complex molecule. One example of monosaccharide is glucose while cellulose (found in plants) and starch (found in animals) are examples of polysaccharides.

Directions: List 5 examples for each type of change to matter.

nirvana33 [79]

Answer:

Physical Change:

- Boiling water

- Breaking a pencil

- Water evaporating

- Denting a car door in an accident

- Tearing paper

- Ice melting

- dissolving

Chemical Change:

- Something rusting

- photosynthesis

- metabolism/digestion

- Nuclear power [atoms are arranged differently]

- Smashing paper with two metal balls, burns paper

- Electricity in water, breaks H2O into H2 and O2

-----

physical change is when there is only physical change occurring--and it can typically be undone easily,

whereas chemical change is when there is chemical change--which changes the chemical properties of something, which cannot be undone simply.

hope this helps!!
