inorganic chemicals definition​

Answers

Simplified definition -> the branch of chemistry that deals with inorganic compounds.

Longer definition -> Inorganic science is the part of science which examines the components, and inorganic mixtures. Inorganic science can be characterized just as all science which isn't natural science. Natural science is essentially the investigation of carbon compounds.

In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. However, the distinction is not clearly defined; authorities have differing views on the subject

Explanation:

It changes to a lesser amount of chemical energy. ... It forms from an equal amount of potential energy. It forms from an equal amount of radiant energy.

The amount of energy that is used up during photosynthesis changes to a lesser amount of chemical energy. That is option B.

What is photosynthesis and it's effects?

Photosynthesis is the process by which green plants that posses chlorophyll traps in energy from sunlight and uses it to convert solar energy to chemical energy which is the form of energy that is useful for living organisms.

This is carried out by the absorption of light by the green pigment, chlorophyll. This helps in the splitting of water molecules which further react with carbon dioxide to form sugar

Therefore, the amount of energy that is used up during photosynthesis changes to a lesser amount of chemical energy because of the sugar that is produced as by product.

What is biological hierarchy?

Biological hierarchy refers to the organization of living organisms into a series of levels, each level being more complex than the one below it. The biological hierarchy begins with the smallest unit of life, which is the cell, and progresses upward to include tissues, organs, organ systems, organisms, populations, communities, ecosystems, and ultimately the biosphere.

Each level of the biological hierarchy is characterized by different properties and interactions. For example, cells are the basic unit of life and perform all the essential functions of an organism. Tissues are groups of cells that work together to perform a specific function, such as muscle tissue, which is responsible for movement. Organs are structures made up of tissues that work together to perform a specific function, such as the heart, which pumps blood throughout the body.

Two humans mate who are heterozygous for earlobe shape where attached earlobes (A) are dominant to free earlobes (a), and earwax quality where dry earwax (e) is recessive to wet earwax (E ). What is the probability that their first child will have dry earwax and attached earlobes

Answers

Answer:

3/16

Explanation:

This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).

According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

* Attached earlobe, wet earwax (A_E_) = 9/16

* Attached earlobe, dry earwax (A_ee) = 3/16

* Free earlobe, wet earwax (aaE_) = 3/16

* Free earlobe, dry earwax (aaee) = 1/16

Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.
