you may have read about alkaline diets that claim that you need to only eat alkaline foods in order to remain healthy according to this philosophy eating acidic Foods acidifies the blood leading to disease but our blood has several buffer systems in place explain what happens when buffers encounter additional hydrogen ions from foods will the pH of the blood decrease

Answers

Answer:

Mechanisms are activated where it is sought to lower the amount of free protons in the blood, that is, to reduce acidity, these mechanisms work between two large systems, the receptor system, the respiratory system and the renal system.

Explanation:

When a metabolic acidosis is entered, either by a food, or by a disease or even an intense physical activity, the lungs seek to generate hyperventilation, to increase the concentrations of oxygen in plasma and absolutely decrease the carbon dioxide concentration, thus not the blood becomes even more acidic.

On the other hand, the digestive system together with the sensory system, will warn this proprioception of the acidity of the plasma and will promote the dilution of these acids with a solvent, which is water, promoting the sensation of thirst.

Finally, the kidneys will seek to retain all the alkaline solutes to neutralize the physiological internal pH, and will release through the urine and the channels of acidic compounds, the products or acid metabolites to the external environment, that is, acid urine excretion.

Active transport moves molecules_____their concentration gradient

Answers

During active transport, molecules move from an area of low concentration to an area of high concentration. This is the opposite of diffusion, and these molecules are said to flow against their concentration gradient. Active transport is called "active" because this type of transport requires energy to move molecules.:)

The Lipid Bilayer

Explanation:

The lipid bilayer has been firmly established as the universal basis for cell-membrane structure. It is easily seen by electron microscopy, although specialized techniques, such as x-ray diffraction and freeze-fracture electron microscopy, are needed to reveal the details of its organization. The bilayer structure is attributable to the special properties of the lipid molecules, which cause them to assemble spontaneously into bilayers even under simple artificial conditions.

The diagram shows two chromosomes paired up.




Which process is being shown?


sexual reproduction

independent assortment

crossing over

chromosome separation

Answers

The diagram is not provided with the question. However, the answer is based on the matter provided with the question and the best of knowledge.

Answer:

The correct answer is - crossing over.

Explanation:

Crossing over occurs in prophase I or metaphase I of the meiosis type of cell division which takes place in the sex cells during sexual reproduction. During this process cells that have two autologous or correspondent chromosomes pair up together so the exchange of genetic material f non-sister chromatids can take place between correspondent chromosomes and result in a new allelic combination. The process is also known as synapsis as the two chromosomes pair up.
