Hydrogen nitrate I believe

The chemical formula for the substance nitric acid is HNO₃. Based on the information from this chemical formula, this means that one single molecule of this substance nitric acid contains a covalent bond of one atom of hydrogen, one atom of nitrogen, and three atoms of oxygen.

Answer:

In 1749 A.D. George Wofan, a French scientist, put forward the theory of evolution of the Earth for the first time. According to his theory the Earth along with other planets and satellites, was formed when a comet moving around the universe stroke the sun many years ago.

Explanation:

In 1775 A.D., a German philosopher Kant put forward another nebular theory, which was later improved by Laplace in 1796. According to him, there was a gaseous mass revolving around the earth. While revolving, this mass began to cool and shrinked resulting many smaller masses. These smaller masses began to move round the larger central mass. This central mass became the sun and over revolving bodies formed planet and satellites.

According to hypothesis proposed by Jeans and Jeffery in 1917 A.D., a big star orbiting round the sun finally approached it. The star with its own attraction caused a tide to be developed from the sun. As this fragmented tidal matter cooled, planets, satellites, etc. were formed and the solar system was created. In this process, the Earth was also formed.

Any two geological Era are as follows:

Palaeozoic era: Palaeozoic era was began from 540 million years ago and ended at 250 million years ago. In this era, the plants and animals were found tohave developed which was found from the studies of the fossils remained in sedimentary rocks. Similarly, it is also believedthat there was a change in atmosphere and whether. This era is divided into six periods.

Mesozoic era: Mesozoic era began from 250 million years ago and ended at 65.5 million years ago. In this era, different types of hills and mountains were formed. It is supposed that the vital conditions for the survival of life on land, water and air were formed. This era is divided into three periods.

Answer:

tritium

Explanation:

a hydrogen atom with:

1 proton 0 neutrons = hydrogen

1 proton 1 neutron = deuterium

1 proton 2 neutrons = tritium

If the hydrogen has a mass of three, then it would be tritium

An atom of hydrogen with an atomic number of one and a mass of three would be a hydrogen isotope called tritium.

Regular hydrogen (also known as protium) has one proton and no neutrons, giving it a mass of approximately 1 atomic mass unit (amu). Tritium, on the other hand, has one proton and two neutrons, giving it a total mass of about 3 atomic mass units (amu). This makes tritium a heavier and less common isotope of hydrogen.

Explanation:

The enzyme DNA polymerase catalyzes the formation of sugar phosphate units along the side of the "ladder". The sugar phosphate units connect one base pair/rung on the ladder to the next one.

Therefore our answer is :

A) DNA polymerase joins individual nucleotides together to form a new complementary strands of DNA. :)

The function of DNA polymerase joins individual nucleotides together to form the new complementary strands of DNA. The correct option is the first one.

DNA polymerase is an enzyme responsible for catalyzing the synthesis of new DNA strands during DNA replication.

It adds individual nucleotides to the growing DNA strand, following the complementary base pairing rules (A with T, and C with G). This process ensures accurate copying of the genetic information from the template DNA strand to the newly synthesized strand. DNA polymerase plays a central role in DNA replication, which is the process by which cells make identical copies of their DNA during cell division.

Answer:

There is no direct correlation between the number of genes and development. Man is a developed creature by nature. Although the fern has 500 chromosomes, it is less developed than the human.

Autotrops are the organisms that can prepare their own food by process called photosynthesis. True bacteria and some archaebacterias are the one performing photosynthesis like plants.

Archaebacteria are a group of microorganisms evolved separately from the bacteria and blue-green algae.

Archaebacteria can also survive in extreme environment. Examples include Halobacterium, Pyrolobus, etc.

Both archaebacteria and bacteria are able to photosynthesize their food.

Thus, correct option is D.

Answer:

Explanation:

the population is evolving

Allele frequency is the probability of the gene in a particular population. The consistently changing allele frequency in a population depicts the process of evolution. Thus, option D is correct.

Evolution is the modification in the transitional or the expansion of the inherited characters passed from the parent to the offspring and successive generations over time through reproductive methods.

The allele or the gene frequency defines the evolutionary pattern as the alleles carry and express the characteristics that were passed. Due to environmental changes, the alleles can get modified for better adaptation.

This adaptation and natural selection allow the organism to evolve from the pre-existing species to adapt and with better traits that enable their survival.

Therefore, option D. the changing frequency depicts the evolving population.

Explanation:

Answer:

There are two ways to do this.  You could actually learn the phases and count each one.  Since you're posting here, it's a safe bet you have no intention of actually learning the material.  The second is to estimate based on the total number of cells.  At any given time, you will have approximately the following percentages for each phase of the cell cycle:

Interphase - 96%

Prophase - 2.5%

Metaphase - .5%

Anaphase - .5%

Telophase - .5%

In the picture, there are about 120 cells.  Now you have to do a little 5th grade math to calculate the approximate mumbers of each phase.  So, for Interphase, we multiply 120 x .96 = 115.  For Prophase we multiply 120 x .025 = 3.  For Metaphase, Anaphase, and Telophase, we multiply 120 x .005 = .6, which rounds up to 1 each.  Now, as I specified, these numbers are approximate.  Looking at the picture, I count three that are in Metaphase, two that are in Anaphase, and at least three in Telophase. And there are more than three in Prophase.  The best way to figure this out is to print the picture and, using a guide from the internet, count the cells in each phase, marking them off as you count them so that you don't recount them.  Good Luck!
