Answer:

B.) water mold

Explanation:

The water mold is a filamentous fungus like organisms that lives in  brackish water, fresh water or wet soils. They are saprophytic, that is, they live on dead organisms. Their reproduction is usually by motile asexual spores (zoospores).The zoospores are of two types namely pear-shaped with apical flagella and kidney-shaped with two flagella on the concave side. Water mold are usually identified by their zoospores.

CaHeK987 [17]

Answer:

True (although question is not clear enough)

Explanation:

Adaptive radiation occurs when <u>organisms evolve from the same ancestor. This process takes place as a result of environmental changes or when they are introduced to or colonize a new environment.</u> These changes become challenges that force these individuals to adapt to these new conditions.

Therefore, <u>this results into a faster evolution that creates different new forms</u> that possess a diversity of variations adapted to their new feeding habits, environment, and behavioral needs.

<em>One of the most famous examples of adaptive radiation is the formation of new forms of Galapagos finches.</em> These striking finches, which arose from a common ancestor, evolved different beak sizes and shapes that were especially adapted to different types of food. As different as they may appear, they are closely related!

Define nuecleotides in your own words
ale4655 [162]

Nucleotides are monomers composed of sugar and phosphate groups and a nitrogenated base. Several nucleotides compose DNA and RNA.

<h3>What are nucleotids?</h3>

Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.

Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.

Several monomers comprise a polymer. In this way, several nucleotides joined by their extremes compose the nucleic acids.

  • Nitrogenated bases are molecules carrying nitrogen and exhibiting the chemical properties of a base. These are purines and pyrimidines.

DNA ⇒ Adenine, Guanine, Thymine, and Cytosine.

RNA ⇒ Adenine, Guanine, Uracyl, and Cytosine

Adenine pairs with thymine or uracil, while guanine pairs with cytosine.

  • Sugar group: Sugar is always a pentose.

DNA sugar group contains deoxyribose, with hydroxyl modifications.

RNA sugar group contains ribose with no hydroxyl modifications.

Nucleotides have a certain order or sequence in nucleic acids, which is significant since these sequences carry biological information necessary to carry out cellular functions.

Why shouldnt you move the objective lense towards the stage when focusing
lys-0071 [83]
REMOVING THE SLIDE FROM UNDER HIGHER POWER OBJECTIVES MAY CAUSE THE SLIDE SURFACE TO HIT THE OBJECTIVE LENS SINCE THE LENS IN THESE OBJECTIVES WILL BE VERY CLOSE TO THE SLIDE. THIS COULD RESULT IN DAMAGE TO THE LENS. b. TO ACHIEVE THE HIGHEST POSSIBLE RESOLUTION WHEN VIEWING THROUGH THE HIGHEST POWER OBJECTIVES.
