Which of the following is not an observation or inference on which natural selection is based?

olga2289 [7]

Answer: B. Poorly adapted individuals never produce offspring

Explanation:

Natural selection is a theory that states organisms adapts to its environment due to differences in their phenotypes. So, <u>individuals with favorable traits are more likely to survive and reproduce</u>. It is a key mechanism of evolution, which is the change in traits of a population over generations.

<u>Populations respond to natural selection if they contain heritable variation </u>among them, wich means that individuals differ in the traits they transmit to their offspring.

Because of the environmental selection pressures, individuals produce more offspring than their environment can support. <u>The pressure determines which individuals will survive and reproduce</u>, while others will die because of predation or diseases. So, natural selection is based on the observations of adapted individuals.

In man, two abnormal conditions, cataracts (C) in the eyes and excessive fragility (F) in the bones, seem to depend on separate

juin [17]

Complete question:

In man, two abnormal conditions, cataracts (C) in the eyes and excessive fragility (F) in the bones, seem to depend on separate dominant genes located on different chromosomes. Normal vision and normal bones are recessive traits. A man with cataracts and normal bones, whose father had normal eyes, married a woman free from cataracts but with fragile bones. Her father had normal bones.

1. What is the genotype of the man with cataracts and normal bones?

2. What is the genotype of the woman with normal vision and fragile bones?

3. What type of offspring might this couple expect?

Answer:

Cc ff
cc Ff
F1) 4/16 = 1/2 = 25% CcFf, cataracts and fragile bones

4/16 = 1/2 = 25% Ccff, cataracts and normal bones

4/16 = 1/2 = 25% ccFf, normal eyes and fragile bones

4/16 = 1/2 = 25% ccff normal eyes, normal bones

These are the components of the reservoirs of carbon that are exchanged in our environment. name these components

Marat540 [252]

Answer:

Carbon is a non-metallic and solid chemical element that is found in certain inorganic compounds and in all organic compounds. There are several types of carbons, which are the following:

CRYSTALS

Diamond: by having a SP 3 hybridization, this carbon is the hardest element. It is characterized by having a tetrahedral structure. It is characterized by being a high quality electrical insulator and is also a semiconductor.

Graphite: this material is composed of numerous sheets that have hexagonally located carbon atoms. Thanks to its SP 2 hybridization it manages to conduct electricity.

AMORPHES

A. Natural: these carbons are impure and are the result of the petrification processes of decomposed organic materials.

Coal: this rock has different percentages of carbon ranging between 50% and 80% of its totality. It is characterized by its black being with greasy or matte sheen, it is brittle, extremely hard and consists of compressed lignite.

Peat: This material is characterized by its abundance of carbon, has a rather dark brown color and is composed of compact organic matter. Something that differentiates it from the other materials is that the peat can crumble.

Anthracite: this mineral is the one with the highest amount of carbon, which reaches 95% of its total composition. It has a characteristic brightness and hardness.

Lignite: this has a texture similar to wood, matter from which it comes. It is brown or black and is formed from compressed peat.

B. Artificial: these are stone carbons which depend on their composition and age.

Animal carbon: this material is the result of bones that undergo dry combustion or distillation.

Coke coal: this fuel is acquired from distilled coal that calcites are added to achieve better combustion. This process is carried out in closed furnaces where the fuel is subjected to extremely high temperatures.

Retort coal: this material, widely used in construction, is a good conductor of electricity and heat. It is characterized by its hardness and is found in retort walls of refractory material. In them, coal is distilled.
