two long polynucleotide chains

A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together

Molecules of DNA are composed of long chains of nucleotides.

Nucleotides are the building blocks of DNA  and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.

The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.

Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.

A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.

Therefore the molecules of DNA are composed of long chains of nucleotides.

Short term atmospheric conditions give information regarding the weather in an area and Long-term precipitation and temperature data can give an indication of the climate of an area, both statement true.

Weather is the collective name for the momentary properties of the lower atmosphere, including precipitation, temperature, humidity, wind speed, direction, and atmospheric pressure. The possibilities are endless: it may be bright, cloudy, rainy, foggy, chilly, hot, windy, stormy, snowy, etc.

Seasons, documented climate cycles, or volcanism are frequently to blame for short-term climate change, which affects shorter timescales.

Long-term climate change affects longer time periods and may be brought on by human activity, variations in the sun's output, or a sluggish recovery from the Flood.

Therefore, weather refers to atmospheric circumstances for a brief period of time, whereas climate refers to long-term, predictable atmospheric conditions.

What else is produced during the combustion of propane, C3H8 is H20, but to understand this reaction, we need to know.....

When an oxidizer sold as a fuel, it is also called liquefied petroleum gas (LPG), which is a mixture of propane with small amounts of

As an odorant to prevent the normally odorless propane from going unidentified. when in leaks. It is used as fuel for stoves and in car engines.

The combustion of propane is a typically exothermic reaction with the evolution of heat:

C3H8 + 5 O2 → 3 CO2 + 4 H2O

With this information, we can say that the combustion product of propane is H2O.

Answer:

120 joule.

Explanation:

Given

For the stone X

Mass (m) = 2 kg

Height (h) = 2 m

Acceleration due to gravity (g) = 10 m/s²

Then we have the formula to calculate the potential energy

P.E 1 = mgh

= 2 * 10*2

= 40 joule

Now for Stone Y

mass (m) = 4 kg

height (h) = 4 m

acceleration due to gravity (g) = 10 m/s²

Now

P. E2 = mgh

= 4 * 10* 4

= 160 joule

Now the difference between their potential energy is

= P. E2 - P. E 1

= 160-40

= 120 joule

The capacity of a rock or other substance to let the passage of water is known as permeability, hence option c is correct.

Groundwater may readily flow through permeable materials because the pore space is linked throughout the rock or sediment. Mud and clay are examples of materials with great porosity yet very limited permeability.

An aquifer is a water-bearing rock that easily transfers water to wells and springs, the aquifers may be dug into and water pumped out.

Therefore, water that falls onto land surfaces flows into water bodies or it may be soaked in the ground, this water flows through the soil and rock which are permeable, hence option c is correct.

Answer: A karyotype test examines these dividing cells. The pairs of chromosomes are arranged by their size and appearance.

Explanation:

In a karyotype, the arrangement of chromosomes is generally done in the order of size, that is, from largest to smallest.

It is the number and appearance of chromosomes. It comprises the length of the chromosomes, the banding pattern, and the position of centromere.

In a human karyotype, the body chromosomes or autosomes are usually aligned in approximate order of size from largest to smallest, that is, from chromosome 1 to chromosome 22.

However, the chromosome 21 is shorter in comparison to chromosome 22. The arms of the chromosomes protruding from either end of the centromere may be classified as long or short, based upon their relative lengths.

The long arm is abbreviated as q and the short arm as p. Each arm is subdivided further and is designated by a number. The locations on chromosomes can be illustrated by using the naming system.

Thus, in a karyotype, chromosomes are arranged on the basis of their size, that is, from largest to smallest.

Spiral Galaxies, Elliptical Galaxies  & Irregular Galaxies

Explanation:

How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.

Explanation:

1.

Rainfall is measured with a rain gauge in inches/millimeters - Most modern rain gauges generally measure the precipitation in millimetres in height collected on each square meter during a certain period, equivalent to litres per square metre. Previously rain was recorded as inches or points, where one point is equal to 0.254 mm or 0.01 of an inch.
