In some states, the highway patrol uses planes carrying radar devices to monitor traffic. As the plane flies over traffic, the radar device can tell the officers how fast each car is moving at that moment in time. The radar device determines the car's

Answers

Answer 1

Answer:

Answer: Radar is a highly upgraded electromagnetic device or technology that helps in determining where an object is located, at what distance it is, and also determines the speed and direction at which an object is moving, and at what angle it is.

It is generally used by the traffic police, for controlling the speed limit of a vehicle or motorbikes in any countries.

Answer 2

Answer: It determines the car's velocity, commonly known as speed.

Answers

Answer:

replication fork

Explanation:

The deoxyribonucleic acid (DNA) is a double-stranded helix composed of two long chains of nucleotides. The replication fork is a Y-shaped structure by which both DNA strands are separated in order to be replicated during cell division. In a cell, DNA replication starts at specific sites in the genome referred to as 'origins of replication'. A replication fork is generated by helicase enzymes that unwind and separate the DNA double helix strands by interrupting hydrogen bonds that hold the two DNA strands together. These DNA strands act as templates for the leading and lagging DNA strands. During DNA replication, the leading strand is synthesized continuously in the same direction as the replication fork, while the lagging DNA strand is synthesized in a direction away from the replication fork, in small pieces of DNA called Okazaki fragments.

What comments do these authors make concerning the relation of bases on one strand of the helix as compared to those on the other strand?

Answers

Answer:

See the answer below

Explanation:

Watson and Crick modeled the structure of the DNA as being made up of 2 strands with each strand composed of a long chain of nucleotide bases. The DNA. The 2 strands are said to be associated by a hydrogen bond and are twisted around each other in a ladder-like manner to form a helix structure.

Specifically on the bases, Watson and Crick modeled that the nucleotide bases component of one strand of a double helix DNA are complementary to the nucleotide bases of the other strand according to the base-pairing rule.

The base-pairing rule states that adenine always pairs with thymine while guanine always pairs with cytosine. This thus means that with the nucleotide sequence of one strand known, the sequence of the other strand of a double helix DNA can be determined.

Most people feel confident that they could identify a living thing from a nonliving thing, but sometimes it’s not so easy. Scientists have argued for centuries over the basic characteristics that separate life from non-life. Some of these arguments are still unresolved. Despite these arguments, there do seem to be some generally accepted characteristics common to all living things. Anything that possesses all these characteristics of life is known as an organism. 1.The scientific term for a living thing is a(n) _____________________

Answers

Answer:

An Organism

Explanation:

In biology, scientists defined the characteristics which distinguished between a living thing that has life and a non-living thing which do not have the life.

The thing or entity that shows the characteristics of life like made of the cell, reproduce, genetic material and many others are known as an organism. Thus the biology is the field of study that studies the different types of organisms like bacteria, protists, animals and plants or living things present on this Earth.

Thus, an organism is the correct answer.

Which of the following statements correctly describes why a series of closely spaced action potentials causes a sustained contraction rather than a series of closely spaced twitches?a. Ca2+ ions are released quickly from troponin, keeping the Ca2+ concentration in the cytosol high between closely spaced action potentials.
b. Release of Ca2+ from the sarcoplasmic reticulum through channels is slow compared to the uptake of Ca2+ into the SR via ATP-dependent pumps, resulting in Ca2+ slowly trickling into the sarcomeres between closely spaced action potentials.
c. When a series of action potentials is closely spaced, there is not sufficient time for Ca2+ uptake into the sarcoplasmic reticulum between action potentials, and Ca2+ remains bound to troponin throughout the series.
d. Fewer Ca2+ ions are released from the sarcoplasmic reticulum as a result of several closely spaced action potentials than as a result of a single action potential.

Answers

Answer:

The correct answer is - option C.

Explanation:

A series of closely spaced action potentials cause the sustained muscle to contract which is only possible if in the sarcomere of muscles the has high Ca2+ during the complete contraction cycle.

If the Ca2+ level is lower due to the sufficient Ca2+ were taken up into the sarcoplasmic reticulum in the sarcomere below the range between each action potential, the muscle would relax because the myosin-binding sites will be covered by tropomyosin.

The Ca2+ channels in the SR are able to move the ions more rapidly than the Ca2+ pumps can move in SR so this will cause the concentration of calcium to always high which leads to the binding of tropomyosin and therefore, the myosin-binding sites would be exposed until the contraction is achieved.

6. If an object is an irregularly shaped solid and it is dropped into a graduated cylinder andit displaces 25 mL of water and has a mass of 50 grams what is the density of this
irregular shaped object?

Answers

Answer:

d = 2 g/mL

Explanation:

Given that,

Water displaced by an object in a graduated cylinder, V = 25 mL

Mass of the object, m = 50 g

We need to find the density of this irregular shaped object. It is given by mass per unit volume. So,

$d=(m)/(V)\n\nd=(50\ g)/(25\ mL)\n\nd=2\ g/mL$

So, the density of the object is 2 g/mL.

What are the different classes of protein ?

Protein is complex biomolecule made up of a multiple chain of amino acid formed by peptide bond which is a linear chain structure and it can be classified into two types such as complete and incomplete proteins.

Complete proteins contain all of the essential amino acids required for the body which include meat, fish, poultry, dairy, and soy products.

incomplete Foods where one or more essential amino acids are absent are called as incomplete proteins which include beans, grains, nuts, and vegetables.

it can be classified into five major Classes such as Enzymes, Structural Proteins, Transport Proteins, Regulatory Proteins and Hormones. where Enzyme catalyse the biochemical reactions in the body and Structural proteins provide support for cells and tissues.
