Which of the following is the correct Lewis structure diagram for Sodium (Na)? (2 points)


Select one:
a. The letters Na with one dot
b. The letters Na with two dots
c. The letters Na with three dots
d. The letters Na with four dots

Answers

Answer:

a. The letters Na with one dot

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.

Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.

A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.

Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.

For example, the Lewis structure diagram for Sodium (Na) is •Na.

Answer:

Na with 1 dot

You are studying nuclear lamins and use recombinant DNA technology to alter the coding sequence of a nuclear lamin gene. The alteration you make creates a situation such that the gene now codes for a nuclear lamin protein that can no longer be phosphorylated when the nuclear envelope is broken down during mitosis. What do you predict would happen if the cell only had the altered nuclear lamin gene (and not the unaltered version)

Answers

Answer:

Nuclear lamins will no longer disassemble during mitosis

Explanation:

The nuclear lamina is a fibrillar network inside the nucleus of eukaryotic cells, between the inner nuclear membrane and the peripheral chromatin. Nuclear lamins (also called simply lamin proteins) are intermediate filament-type proteins and represent the major building blocks of the nuclear lamina. During mitosis, the nuclear lamina is disassembled by hyperphosphorylation of nuclear lamins and lamina-associated proteins. The protein responsible for phosphorylating nuclear lamins is p34cdc2, a protein kinase that has a key role in controlling cell cycle progression. In consequence, a mutant form of the nuclear lamin proteins that cannot be phosphorylated will no longer be able to disassemble during mitosis.

How do mitochondria differ from chloroplast

Answers

Explanation:

Mitochondria and chloroplast are organelles found in a plant cell. However, chloroplast is absent in an animal but mitochondria is found in both.

Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients while Chloroplast is the site for photosynthesis in a plant cell.

Answer:

Mitochondria

Known as the powerhouse of the cell, it is responsible for energy metabolism and cellular respiration.

chloroplast

Larger and much more complex than a mitochondrion, it is the site where photosynthesis takes place.

outline the role of the liver in excretion. ​

Answers

Answer:

Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin.

Carbon dioxide

The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.

While working with cultured mouse cells, a researcher unknowingly treated the cells with a mutagen that causes the deletion or insertion of individual nucleotides in DNA. Subsequently, she isolated and cultured a single cell from this group. She noticed that the progeny of this cell were not producing a certain protein and that this affected their survival. The mutation would be most harmful to the cells if it resulted in ______.

Answers

Answer:

The correct answer is - a single nucleotide insertion near the start of the coding sequence.

Explanation:

Insertion mutations are the mutation that takes place when there is an extra nucleotide is added to the DNA strand during replication and causing the particular protein translation or inhibits the translation if present at the start codon.

It did not allows the translation in this sequence, Deletion, and insertion both are a dangerous mutation that causes the production of unwanted protein or not producing the protein and if this protein is essential for surviving it will lead to cell death.

Your welcome❤️

Answer:

yes

Explanation:

the chromosome number of the egg and and sperm are halved ,and are then joined together. the fusion of the the nucleus of the haploid male gamete with the haploid female gamete is referred to as fertization and the product of fertilization is zygote.

The diploid single zygote then divides repeatedly and develops to produce the offspring whose somatic cells are diploid.The zygote is the initial stage in baby development. It is also known as a fertilized ovum formed from the union of the sperm cell and the egg cell. Foetus refers to the final stage in baby development.

Determine if the process is an example of anabolism or catabolism.​ French fries are digested in the intestine, breaking them into smaller molecules A body builder exercises to build muscles through protein synthesis A child eats a milkshake, which provides her with energy Process Catabolism

Answers

Answer:

--> French fries are digested in the intestine, breaking them into smaller molecules.(Catabolic process)

--> A body builder exercises to build muscles through protein synthesis. (Anabolic process)

--> A child eats a milkshake, which provides her with energy (catabolic process).

Explanation:

CATABOLISM is the process by which living organisms break down large or complex molecules into smaller molecules with the release of energy for their own use. Foods that we consume contains different nutrients which includes carbohydrates, fats &oil, and protein. These nutrients are made available for our body cell use and maintenance through the process of catabolism. Through catabolic processes, these nutrients are broken down into its smaller constituents with the release of energy which is used immediately to power molecular machines that support cell, tissue, and organ function. The following are examples of a catabolic process as it involves breakdown:

--> French fries are digested in the intestine, breaking them into smaller molecules and

--> A child eats a milkshake, which provides her with energy

In contrast, anabolic process involves the building up larger molecules from smaller ones. It uses ATP molecules generated by catabolic reactions as a form of energy to create new molecules that form new cells and tissues, and revitalize organs. For example, muscles can be built from the synthesis of proteins. This is also called anabolic training.

French fries are digested in the intestine, breaking them into smaller molecules - Catabolic process

A body builder exercises to build muscles through protein synthesis - Anabolic process

A child eats a milkshake, which provides her with energy - Catabolic process

Catabolism can be defined as the break down of larger molecules into smaller ones in a series of metabolic pathways of which the energy produced undergoes oxidation and then is released or it is used in another reaction. Digestion is an example of a catabolic process i.e. French fries are digested in the intestine, breaking them into smaller molecules. A child eating a milkshake, which provides her with energy (energy is produced) is a catabolic process.

Anabolism involves the build up of molecules from smaller molecules usually needed for bodily functions. Protein synthesis is an anabolic process (buildup from small amino acids to large proteins. A body builder exercises to build muscles through protein synthesis is an example of anabolism

Explain why your model improves upon the student’s original model. How would your model help someone who was learning about photosynthesis for the first time? Plato question

Answers

Answer:

Due to inclusion of more steps of photosynthesis.

Explanation:

My model is more advance than the student's original model which provides more information about the process of photosynthesis to the learners by explaining various parts of photosynthesis. My model presents the various steps of photosynthesis in a very efficient way with the help of including some extra parts. The student's original model is not more advance so it can't provides more information about the process of photosynthesis so that's why my model provides more information about photosynthesis.

Answer:

This model shows all the major molecules involved in the Calvin cycle and how they change at each stage of the process. This added detail would clarify that the Calvin cycle is a series of complex steps. The student’s original model didn’t show this breakdown at all, and it shows only the final products. This model also shows the number of each molecule created, which the original model doesn’t do.
