Describe how oxygen is transported in blood, and explain how temperature, pH, BPG, and affect oxygen loading and unloading.

Answers

Solution :

The flow of oxygen in the blood is been transported by two ways :

1. in plasma 1.5%

2. bound to hemoglobin 98.5%

As the oxygen loads in the body, affinity of the Hb makes the oxygen loading very efficient in the blood. The Hb molecule gets saturated when all the 4 hemes are oxygen binded.

The decreased pH weakens the hemoglobin oxygen binding in the tissues.

Higher temperatures in the oxygen means a lower affinity and thus more oxygen is released and so the oxygen unloads.

Increase in the temperature, the BPG and the modification of the structure in the hemoglobin decreases the affinity for the oxygen and further enhances the unloading of the oxygen in the blood.

Answers

Answer:

ventilation

Explanation:

Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.

Answers

it’s just because the answer is this melanin both of them have it

Albinism is a recessive trait where an individual does not produce the pigment melanin. Albinism is an autosomal disease where the gene which is expressed here is having albinism which is the cause of heterozygous condition.

What is the heterozygous ?

Heterozygous is the condition where the genes in the alleles are different to each other where one has a dominant character and one has a recessive character. The genotypes of the woman and man decide the genotype of the offspring.

The genotypes of the man and woman is heterozygous where the dominant once out of 3 will have the dominant traits for the albinism. The condition will have to be heterozygous as in the Ia Ii gene where the gene for the albinism   will be i gene.

The same genotype for the male where the Ib i gene in which i i the albinism carrying gene here the ii condition of the gene will express the albinism.

Explanation:

What you would expect to see following the bathing of a sensory neuron in  tetra ammonium chloride and MgCl2, given that the voltage clamp moves from -70 to -5 mV is A brief positive current inward due to sodium entry through voltage gated sodium channels.

This is because as Cl^- enters the cells it causes the entrance of  Na^+ into the cell ( i.e. voltage gated Na^+ ions channels will open ) hence the mixture will cause a lower negative membrane potential to be present .

Explanation:

Dispersion refers to the change in an organism's range or distribution area. Different ecological and biogeographical processes might be involved in organisms' dispersion. The term "jump dispersion" refers to a few individuals in a short time that can cross a barrier and occupy a new area. In this situation, the establishment is not always for sure. For this to happen, they must reproduce and start a new population of a certain size that can survive the new conditions.  

Biologic Invasions refer to new species that establish in a new area far or out of their original distribution range. Once established, these species might be considered exotic or invasive, according to their reproductive rate, population growth, and interaction with native species.

The exotic species is the one that has been introduced and got to establish, but causes no damage or alteration to native ecosystems.

The invasive species is introduced into a new area, establishes, expands its distribution from the first invaded spot, and overgrows. As they expand, they compete with other native species for resources such as water, place, radiation, exposure, shelter, source of food, among others. Species are considered to be invasive because of their reproductive rate, population growth, and interaction with native species, which provokes huge damages to the native ecosystem.

It is very common for these species to escape and start new populations in the new area, where they have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their establishment.

There are some typical steps in an invasion process:

1) Introduction or dispersion to the new area,

2) Naturalization. The new species establishes in the new area. It can grow, reproduce and make use of resources.

3) Overgrowth and uncontrolled expansion.  

4) Interaction with other species.  

5) Stabilization.  

Biologic invasions are natural processes, that occur in small groups of individuals that can expand to other ecosystems. Their expansion is promoted by the appearance or disappearance of barriers.  But these biological invasions have been accelerated by human beings, referring to this as human-assisted invasions. These are the cases in which men transport species from one place to the other for different uses or purposes.

Once a species has become invasive, it turns very hard to eliminate it, especially because it requires big mechanical and economical effort. However, they can be controlled to avoid their wider expansion. There are different ways of controlling invasive species
