Answer:

(When molecules move in this way, they are said to move down their concentration gradient.) Three common types of passive transport include simple diffusion, osmosis, and facilitated diffusion. Simple Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

1. True/False: DNA replication is considered "semi-conservative" because only half of the chromosomes are copied during S phase

BARSIC [14]

Answer:

1) The statement is false

2) Option A) deoxyribose, phosphate, and a nitrogenous base

Explanation:

1) In semi-conservative DNA replication:

- a parent double-stranded DNA splits in two.

- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand

- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.

Thus, because the parent strand is retained in the newly synthesized DNA, DNA replication is described as semi-conservative

2) DNA consists of several repeating units of polydeoxynucleotides where each is made up of a nitrogenous base (Adenine, thymine, cytosine or guanine) linked to

deoxyribose sugar by an N-glycosidic linkage, and then the sugar linked to a phosphate group by phosphoester bond.

Vadim26 [7]

Biomolecules are important for living organisms and vital for cell structure and functioning. The cells are made up of biomolecules as their structural organization.

The four most abundant biomolecules are:

<u>Carbon, Oxygen, Nitrogen and Hydrogen</u>

The biomolecules can be explained as:

The central biomolecules for life activities are these elements that contribute to major processes.

The main building blocks like carbohydrate is composed of carbon, oxygen and hydrogen. They provide energy to the body by breaking into small molecules.

Proteins are vital for cell signalling and transport. They are composed of amino groups consisting of nitrogen.

Therefore, carbon, nitrogen, hydrogen and oxygen are the most abundant biomolecules.

To keep the humeral head centered within the glenoidal cavity the rotator cuff muscles must be __________. Select to launch anim

enyata [817]

Answer:

<h2> located in the same plane</h2>

Explanation:

Such types of muscles and tendons that play an important role in the stabilization of the shoulder are called rotator cuff muscle.
These muscles are responsible for the different types of motion and simply called a different range of motion.
Muscles like scapulohumeral muscles, infraspinatus muscle and some others are grouped as rotator muscle.
These muscles are involved in the movement of the shoulder and also stabilize the joints of the shoulder for the movement and during the movement.
When the humeral head is centered within the cavity of the glenoidal then the rotator cuff muscle should be on the same plane.
