Consideting the definition of compound, the correct answer is second option: Carbon, hydrogen and chlorine atoms combine chemically, forming compounds.
A compound is any substance formed by the union of two or more types of chemical elements, linked together by chemical bonds.
In other words, A chemical compound is the substance that results from the combination of two or more different chemical elements linked under a certain arrangement and in certain proportions.
Each compound has a chemical name (which responds to certain nomenclature rules) and a formula that indicates the elements it is composed of and the number of atoms each contains.
Then, the correct answer is second option: Carbon, hydrogen and chlorine atoms combine chemically, forming compounds.

Answer:
he has heterochromia iridis
Explanation:
Scherzer has an uncommon condition called heterochromia iridis that affects less than 200,000 people in the United States. The condition, which in most cases doesn't damage the eyes, is caused by the distribution and levels of melanin in the irises

Ozone levels in 1920 were primarily monitored using chemical methods, such as the use of chemical indicators and colorimetric analysis.
Potassium iodide-starch paper was used to detect ozone. When exposed to ozone, these indicators changed colour, letting researchers visually monitor ozone concentration.
Colorimetric analysis was also used. Chemical reagents reacting with ozone changed colour. Ozone concentration connected with colour change intensity. Chemical approaches measured ozone qualitatively or semi-quantitatively. They were easy to use but less precise than modern monitoring approaches.
In the following decades, spectrophotometry and ozone analyzers improved the systematic monitoring and quantitative measurement of ozone levels. These improvements made atmospheric ozone monitoring more precise.

For many generations, the flowers in a meadow have been pollinated by a particular species of honeybee. One year, a new species of
honeybee moves to the meadow. This new species pollinates the same flowers as the old species. Which description best predicts
what would happen if a new species of honeybee moves into a meadow that was already occupied by a particular honeybee that
pollinated the meadow?
Answer:
By the process of mating there will be again undesirable species (hybird) and the particular honey bee might get extinct.
There will be imbalance in ecosystem if a new species of honey bees moves into a meadow that was already occupied by a particular homey bees.

Answer:
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.

Explain how the model of the chemical reaction above demonstrates that matter is conserved.
Answer:
Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions

What is recombinant DNA ?
Recombinant DNA are the molecule which has been modified to include genes from different origin by the process of either genetic recombination or through laboratory techniques.
In the lab condition, bacteria can be transformed with recombinant DNA and Genetic recombination occurs via crossing over.
scientists use this recombinant DNA technology created to add to the genome of another organism which means that scientists can easily add genes from one species into bacteria for the production of the product.
For example, insulin is produced by recombinant DNA technology within bacteria where human insulin gene is inserted into a plasmid, then introduced to a bacterial cell, followed by the production of insulin by bacteria cell.

Answer:
its a naturally occurring mineral
Explanation:
Gypsum is made up of oxygen, sulfur, calcium and water. As evaporation occurs the sulfur is not protected by the water and oxygen contacts sulfur bonding with it to form a sulfate. The sulfate then bonds with calcium and water to create gypsum.

Answer:
mitosis animal y vegetal son dos tipos de divisiones nucleares reproductivas en animales y plantas, respectivamente. Durante la mitosis, la cantidad de material genético permanece igual. Por lo tanto, aumenta el número de células en el cuerpo durante el crecimiento, la reparación y la regeneración. La mitosis ocurre en cuatro pasos principales; Profase, metafase, anafase y telofase. los diferencia principal Entre la mitosis animal y la mitosis vegetal es que el huso mitótico en la mitosis animal se forma con la ayuda de dos centriolos, mientras que el huso mitótico en la mitosis vegetal se forma sin ningún centríolo. La mitosis es seguida por citocinesis

An arrangement of all the chromosomes of a diploid cell is called a(n)
Answer:
An arrangement of all the chromosomes of a diploid cell is called a kayrotype
An arrangement of all the chromosomes of a diploid cell is called a karyotype is the overall look of all the chromosomes in a species or an individual organism's cells.
What is the karyotype?A karyotype is a eukaryotic cell's nucleus' number and arrangement of chromosomes. The phrase is also used to refer to a species or an individual organism's entire set of chromosomes.
Each diploid cell in humans contains 46 chromosomes. There are 22 pairs of autosomal, or non-sex, chromosomes and two chromosomes that determine sex among them. A diploid cell has 2n total chromosomes, which is twice as many as a haploid cell's total chromosomes (n).
Therefore, a karyotype is the overall look of all the chromosomes in a species or an individual organism's cells, primarily their sizes, numbers, and shapes.
