There are three alleles that determine blood type in humans: A, B, and O. If the frequency for the A allele in a population is 0.258 and the frequency for the O allele is 0.673, determine the frequency of the B allele.

Answers

Answer 1

Based on the given frequencies of the other alleles, the frequency of the B allele in the population is 0.069.

What is the frequency of allele B?

The frequency of the B allele can be calculated by subtracting the frequencies of the A and O alleles from 1, since these are the only three alleles that determine blood type:

Frequency of B allele = 1 - Frequency of A allele - Frequency of O allele

Frequency of B allele = 1 - 0.258 - 0.673

Frequency of B allele = 0.069

Therefore, the frequency of the B allele in the population is 0.069, or approximately 6.9%.

what improves the productivity of cellular respiration? group of answer choices the presence of an intermembrane space the presence of free ribosomes in the mitochondrial matrix highly folded surface of the inner mitochondrial membrane the presence of multiple circular dna molecules in the mitochondria

Answers

Cellular respiration is improved by the presence of the highly folded surface of the inner mitochondrial membrane. Thus the correct option is c.

Cellular respiration is a metabolic process that releases energy stored in glucose molecules in the presence of oxygen. The mitochondria are the organelles that conduct cellular respiration.

Mitochondria contain a highly folded inner membrane that increases the surface area available for chemical reactions to occur.

The inner mitochondrial membrane is highly folded into cristae, which increases the amount of space for the electron transport chain to occur.

This gives the electron transport chain more surface area to work with, improving the productivity of cellular respiration.

Therefore, it is the highly folded surface of the inner mitochondrial membrane that improves the productivity of cellular respiration. Thus option c is correct.

Sandra was having trouble breathing and needed an Xray. Which of the following muscles could help Sandra for deeper inspiration?Transversus thoracisExternal obliqueExternal intercostalInternal intercostalWhy? After choosing your answer, describe the functions of the other muscles.

Answers

The muscle that could help Sandra with deeper respiration is the external intercostal muscle.

X-ray is a diagnostic tool that doctors use to identify the internal structure of a patient's body. Sandra's external intercostal muscles are the muscles that can help her breathe more deeply. The external intercostal muscles, as the name implies, are located between the ribs and work together to lift the ribcage and increase the volume of the chest.

By contracting and relaxing, the muscles allow the lungs to fill with air. The internal intercostal muscle. The internal intercostal muscles are located beneath the external intercostal muscles and operate to lower the ribcage during exhalation.

When Sandra exhales, the internal intercostal muscles contract and bring the ribs down and forward. Transversus thoracic muscles. The transverse thoracic muscles are located within the anterior thoracic wall, and they help in the exhalation of air from the lungs.

When Sandra breathes out, the transversus thoracis muscles help to reduce the thoracic cavity's volume, forcing the air out. If Sandra were having difficulty breathing, these muscles would not be able to help her. External oblique muscles.

The external oblique muscles are located in the abdominal region and not in the thoracic region. They are not involved in breathing, so they would be of no help to Sandra in this case.

The strength of hemoglobin's binding to oxygen is dependent on several factors. Out of the following, which is the situation where hemoglobin will bind to oxygen most tightly?
In areas of low concentration of oxygen
In the lungs
In the body tissues
In areas of high carbon dioxide concentration
All of the above would have approximately the same affect on the binding of hemoglobin to oxygen

Answers

The strength of hemoglobin's binding to oxygen is dependent on several factors. Hemoglobin will bind to oxygen most tightly in the lungs.

What is Hemoglobin?

Hemoglobin is an iron-containing protein in red blood cells that carries oxygen to the body's tissues and organs. Hemoglobin's iron atom binds to oxygen molecules as oxygen enters the lungs, causing the iron atom to change shape and grab additional oxygen molecules.

When a molecule of oxygen binds to a heme group, it induces a conformational change in the hemoglobin molecule that makes it easier for more oxygen to bind. Hemoglobin's binding affinity for oxygen is determined by a variety of environmental and physiological factors.

In the lungs, hemoglobin binds most tightly to oxygen because there is a higher concentration of oxygen present, which increases the likelihood of hemoglobin-oxygen interactions. Hemoglobin's binding affinity for oxygen is also influenced by pH, carbon dioxide concentration, temperature, and pressure; however, in the lungs, the concentration of these factors is favorable for oxygen binding.

What happens when stimulus exceeds the threshold potential?

Answers

When stimulus exceeds the threshold potential, it causes an action potential to occur. An action potential is a rapid electrical signal that travels along the axon of a neuron.

It is triggered by a rapid change in the membrane potential, which occurs when stimulus exceeds the threshold potential. The action potential results in the release of neurotransmitters which can then cause an effect in another neuron. A stimulus is something that triggers a response in an organism or a cell. A stimulus could be a change in temperature, pressure, or sound, as well as a chemical substance such as hormones, neurotransmitters, or light energy.

When a stimulus exceeds the threshold potential, an action potential is triggered. The sodium channels in the neuron membrane open when an action potential is triggered, allowing the influx of sodium ions into the cell. As more and more positively charged sodium ions enter the cell, the inside of the neuron membrane becomes more positively charged, depolarizing it. As the inside of the neuron membrane becomes more positively charged than the outside, the potassium channels open, allowing the outflow of positively charged potassium ions from the cell. This outflow of potassium ions helps to restore the negative membrane potential, repolarizing the neuron membrane.

The action potential propagates along the length of the neuron's axon, causing the release of neurotransmitters from the axon terminal when it reaches the synapse. The neurotransmitters bind to receptor proteins on the surface of the receiving neuron, generating a new electrical signal that continues the process of information transfer.

Answer:

Some diseases caused by smoking:

Heart disease

Emphysema

Respiratory Infections

Cancer of the mouth and throat, oesophagus / esophagus, stomach, colon, rectum, liver, pancreas, voice box (larynx), trachea, bronchus, kidney and renal pelvis, urinary bladder, and cervix.

Explanation:

Heart Disease: A person's arteries might get blocked as a result of smoking. This prevents proper blood flow, which might result in a heart attack or stroke.

Emphysema (a lung disease): The lungs' alveoli are damaged by the chemicals in tobacco smoke. Their walls weaken, and when you breathe in, they don't properly inflate. Coughing may cause them to explode. As a result, less oxygen is transported through the bloodstream, which causes shortness of breath.

Respiratory Infections: Mucus is produced by the cells in your trachea, which serves as a filter for dust and bacteria. Moreover, your airways are kept clear by cilia, which push mucus into your stomach. The cilia are prevented from moving by chemicals in tobacco smoke. This allows for mucus to enter your lungs, which makes breathing difficult and frequently results in infections. Smokers cough this mucus up, which can harm the lungs further.

Cancers: At least 70 of the over 5000 chemicals released by cigarette smoke can cause cancer. In our lungs, the dangerous chemicals spread throughout our entire body. DNA is harmed by cigarette chemicals. Cells have a tougher time repairing any DNA damage due to the chemicals in cigarettes. Moreover, they harm the DNA that guard against cancer. Cancer is brought on by the build-up of genetic damage in a cell over time.
