Explanation:

Answer:

The reaction catalyzed by an enzyme is very specific. Most enzymes are proteins with unique three-dimensional configurations based on their amino acid sequence. The specificity of an enzyme can be attributed to the compatibility between the shape of the enzyme's active site and the shape of the substrate

Answer:

enzymes have a 3D shape to basically fit, like a puzzle and if it doesnt fit there is no activity

Answer:B NUCLEOLUS IS WHERE DNA IS STORED

BRAINLIEST MEEEE

Explanation:

The nucleolus is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis. AKA DNA !!!!

The function of the nucleolus includes 'beginning ribosome assembly'.

The nucleoli are eukaryotic organelles located within the cell nucleus that act as ribosome factories, in which the process of transcription (i.e., RNA synthesis) occurs constantly.

The nucleolus serves to make ribosomal subunits and then it sends ribosomal subunits to different cell destinations where they form full ribosomes.

In conclusion, the function of the nucleolus includes 'beginning ribosome assembly'.

Electromagnetic waves transfer energy by they cause vibrations in electric and magnetic fields.

Electromagnetic radiation consists of waves of the electromagnetic field, which propagate through space and carry momentum and electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays.

Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

Electromagnetic radiation exhibits wavelike properties such as reflection, refraction, diffraction, and interference, but also exhibits particlelike properties in that its energy occurs in discrete packets, or quanta.

DNA is found in the nucleus. So B.

Explanation:

DNA is found in chromosomes and chromosomes are found in the nucleus because the nucleus is basically the DNA of a cell.

In the nucleus, cell structures are the Drosophila chromosomes (DNA) located. The correct option is B.

The thread-like components known as chromosomes are found in the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).

DNA is passed down from parents to children and contains the precise instructions that give each kind of living thing its individuality.

a component that can be found in a cell's nucleus. Proteins and DNA are arranged into genes on a chromosome. There are typically 23 pairs of chromosomes in each cell.

One chromosome is made up of one protein and one DNA molecule. Different chromosome sizes can be packed together into a nucleus thanks to proteins called histones.

The DNA for the Drosophila chromosomes is found in the cell's nucleus.

Thus, the correct option is B.

Answer:15.94 m/s

Explanation:

Apex

Answer:-15.94m/s

Explanation:

Answer:

1. metaphase II - 7.3 pg.

2. prophase I - 14.6 pg.

3. G1 - 7.3 pg.

4. after cytokinesis of meiosis II - 3.7 pg.

5. telophase I before cytokinesis - 14.6 pg.

6. G2 - 14.6 pg.

Explanation:

The cell cycle begins at G1, where all cells in humans (except for the gametes) have 23 pairs of chromosomes, 46 in total, and without any part of the DNA being duplicated. This is the stage in which the cell will have 7.3 pg of DNA.

After G1 comes phase S, which is the phase in which the DNA is duplicated to prepare the cell for the oncoming division; so we can infer that the phase that comes after S, G2, will have twice the DNA the cell had initially: 14.6 pg.

With this amount of DNA, the cell enters the first part of meiosis, in which the homologous chromosomes will be separated into two cells that will each carry on with the second part of meiosis. In prophase I, the cell is just beginning the process of meiosis, so it has 14.6 pg of DNA. In telophase I, the cell still has that amount of DNA because cytokinesis hasn't happened yet, and that is the defining step that ends up actually dividing the cell into two.

Meiosis II begins after cytokinesis I, therefore, the homologous chromosomes have already been separated and each cell has now 7.3 pg. In metaphase II the cell has 7.3 pg, but when cytokinesis of meiosis II ends, the cell will be half the size that was just before, because the sister chromatids are separated - this is where the cell will only have 3.7 pg of DNA.

The cells produced by meiotic cells are gametes, having only 23 chromosomes and the lowest amount possible of DNA.

Answer:

detail is given below

Explanation:

We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. Proton has positive charge  P⁺   and neutron is neutral  n⁰ .

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The number of protons and electrons are always equal to make the atom electrically neutral and when an atom loses its valance electron the number of protons increases and thus positive charge increased and atom form cation.

Cation formation:

X → X⁺ + e⁻

When an atom gain electron negative charge increase because of more number of electron thus atom form negative ion or anion.

Anion formation:

X + e⁻ → X⁻

1) If an atom loses an electron, it becomes... (positive ion)

2) If an atom gains an electron, it becomes... (negative ion)

3) A hydrogen atom loses an electron. It becomes...(positive ion)

4) A sodium ion (Na) can ionically bond with which?

Sodium ion (Na⁺) can ionically bonded with Cl⁻ , thus both form salt which sodium chloride. Sodium ion can not bonded with hydrogen and potassium because both are also form cation.

5) If an atom gains or loses a neutron, the charge of that atom changes.

The given statement is false because neutron is neutral so when it added or removed from an atom there will be no effect on charge.

6. If an atom gains or loses an electron, the atomic mass of that atom changes.

The given statement is also false because atomic mass is sum of number of neutron and protons. So when electron is added or lost by an atom there will be no effect on atomic mass.

7. If an atom gains or loses a neutron, the atomic mass of that atom changes.

The given statement is true. Atomic mass is sum of number of neutron and protons. So when neutron is added or lost by an atom there will be effect on atomic mass. The atomic mass will be increase or decreased.

8. An atom with  valence electrons can covalently bond with another atom.

The given statement is true. The valance electrons of an atom are involved in bonding. It could ionic, covalent or any other type.

Answer:

When an earthquake occurs the seismic waves (P and S waves) spread out in all directions through the Earth's interior. Seismic stations located at increasing distances from the earthquake epicenter will record seismic waves that have traveled through increasing depths in the Earth.

Seismic velocities depend on the material properties such as composition, mineral phase and packing structure, temperature, and pressure of the media through which seismic waves pass. Seismic waves travel more quickly through denser materials and therefore generally travel more quickly with depth. Anomalously hot areas slow down seismic waves. Seismic waves move more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid. Partially molten areas may slow down the P waves and attenuate or weaken S waves.

When seismic waves pass between geologic layers with contrasting seismic velocities (when any wave passes through media with distinctly differing velocities) reflections, refraction (bending), and the production of new wave phases (e.g., an S wave produced from a P wave) often result. Sudden jumps in seismic velocities across a boundary are known as seismic discontinuities.

Within the Earth, molten areas slow down P-waves and stop S-waves because shearing motion of the waves cannot be transmitted through a liquid.

Earthquake cause the seismic waves (P and S waves) that spread out in all directions even in the Earth's interior. Seismic waves move more slowly through a liquid than a solid.

Within the Earth, molten areas slow down P-waves and stop S-waves because shearing motion of the waves cannot be transmitted through a liquid.

Therefore, most of the S-waves of an earthquake disappear about a distance of 11,500 km from the epicenter.
