Answer:

A model is used to simulate reality. Although a model can be effective in a number of ways but still it has many drawbacks. Some of the drawbacks are:

They cannot replace reality. Not all the factors influencing a certain event can be studied while generating a model. Hence, there is always a difference between a model and reality.
Most models are just approximations and explain things in a convenient manner. They cannot depict the actual complications of a system.

classify if the recessive allele fibrosis is represented as c classify fibrosis is represented as c,classify the following genot

IrinaVladis [17]

Complete question:

If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.

Answer:

CC - homozygous dominant

cc - homozygous recessive

Cc - carriers

cc will have the phenotype

Explanation:

Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.

Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease

In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype

Scientists find the fossilized remains of a fish in the middle rock layers of a research site. They find the fossil of an insect

Neporo4naja [7]

It is A I think the insect lived first and so it is under because it is under a different layer so if they were around at the same time and the fish was just under water it would be in the same layer of rock but because it is different rock it was not around at the same time

Cells responsible for information processing and transfer are

Darya [45]

Answer: C). Neurons

Explanation:

Neurons are the specialized cells present in the brain. These cells play an important role in processing and transfer of information generated as a response to stimuli. The neurons have specialized parts which recieves the signals from dendrites and send the signal to other neuron by axon. In this way transfer of information takes place from cell to cell.

Place the respiratory structures below in the order that air would pass through them as it moves from the outside to the inside

Marizza181 [45]

The respiratory structures in order that air moves from outside to inside include primary bronchus--> secondary bronchus--> Tertiary bronchus--> terminal bronchioles--> respiratory bronchioles--> alveolar duct--> alveolar sacs--> alveoli.

<h3>What is respiratory system?</h3>

The respiratory system is one of the major systems of the body that helps in the oxygenation of the blood which is used by the body cells for oxidation.

Respiration occurs as we breath in air or oxygen and breath out carbon dioxide as used air from the body.

The correct flow of this air from outside to the inside of the body through the following order:

The primary bronchus: This is the first division of from the trachea at the carina forming two bronchi which leads to the left and right lungs.

The secondary bronchus: This divides form the primary bronchus.

The tertiary bronchus: This divides from the secondary bronchus to to supply each segment of the lungs.

The terminal bronchioles: This divides from the tertiary bronchus

The respiratory bronchioles: This divides for the terminal bronchioles.

The alveolar duct, alveolar sacs and alveoli is the main area that oxygen is exchanged with the blood.

primary bronchus--> secondary bronchus--> Tertiary bronchus--> terminal bronchioles--> respiratory bronchioles--> alveolar duct--> alveolar sacs--> alveoli.
