Answer:

True

Explanation:

The eyespot is an organ that helps in light reception and is usually present in unicellular organisms and some multicellular invertebrates.
The eyespot is also present in Euglena, which is a green unicellular organism and the eyespot helps it to receive and detect light.
The light detection helps the euglena to move as the eyespot is located at the base of the flagellum and this eyespot helps influence the flagellar motion.

Use the drop-down menus to label the parts of a nucleotide.

murzikaleks [220]

The parts of one nucleotide a nitrogenous bases (labels C and D), a pentose sugar (labels B and E) and phosphate group (labels A and F).

<h3>What is a nucleotide?</h3>

A nucleotide is a building block of nucleic acids (either DNA or RNA) that form the genetic material of an individual.

Phosphate groups form the backbone of the double helix and bind to pentose sugars in adjacent nucleotides.

Nitrogenous bases bind opposite DNA strands by hydrogen bonds, they include Adenine (A), Guanine (G), Cytosine (C) and Thymine (T).

In this case, the labels include:

Label A: phosphate
Label B: deoxyribose sugar
Label C: nitrogenous base
Label D: nitrogenous base
Label E: ribose sugar
Label F: phosphate

In conclusion, the parts of one nucleotide a nitrogenous bases (labels C and D), a pentose sugar (labels B and E) and phosphate group (labels A and F).

Wall lizard moves on wall due to - Vacuum creation c) Leg Tail d) Naiil

r-ruslan [8.4K]

Answer:

here you go...

Explanation:

Lizards have a large number of very tiny hairs on the pads of their feet called setae. These tiny pads therefore drastically increase the surface area and come in intimate contact with the surface on which the lizard is crawling, so the Van der Waals forces kick in.

The following statement compares different starches: Because it is branched and can be broken down to ________ by multiple enzym

Law Incorporation [45]

Answer:

monosaccharides

amylopectin

amylose

Explanation:

Monosaccharides is any of the class of sugars such that it cannot be hydrolysed into a simpler sugar.

Amylopectin is the non-crystallizable form of starch that consists of a branch of polysaccharide chains.

Amylose is the crystallizable form of starch that consists of an unbranched polysaccharide chains

The following statement compares different starches: Because it is branched and can be broken down to <u>monosaccharides</u> by multiple enzymes at the same time, <u>amylopectin</u> is digested more quickly than <u>amylose</u>.
