The renal system control [HCO₃⁻] and [H⁺], while the respiratory system controls the CO₂ release. Option 5. the respiratory system expels CO₂ produced by the buffer system.
How the bicarbonate buffer system works?Bicarbonate buffer is a significant key in regulating the organism's blood pH.
Bicarbonate is the conjugate base of carbonic acid.
H⁺ + HCO₃⁻ ⇒ [H₂CO₃]
The carbonic acid is converted into CO₂ and water by carbonic anhidrase
[H₂CO₃] ⇔ CO₂ + H₂O
The lungs and the kidneys are responsible for the pH control in corporal fluids.
Water is absorbed by the system, while the respiratory system releases CO₂, which is neurologically controlled. Physiological mechanisms at a renal level control the concentration of [HCO₃⁻] and [H⁺].Consequently, the blood pH control depends on the relative proportion of added HCO₃⁻ by the kidneys and CO₂ eliminated by the lungs.
H₂CO₃ would have a low buffering capacity in the body if it could not dehydrate to CO₂, a gas expelled from the body with expired air.
The correct option is 5. The bicarbonate buffer system would not work very well in the human body if not for the action of the respiratory system, which expels CO₂ produced by the buffer system.

A dimpled man and a non-dimpled woman have 10 children, all dimpled. We might be tempted to assume that the father homozygous for the dimpled trait. Do we know this
DD is homozygous dominant, the dominant allele will shown so they will have dimples.
What is homozygous?When an organism is homozygous, it contains two copies of the same allele for a gene. When two copies of the same dominant allele or two copies of the same recessive allele are present in an organism, it is said to be homozygous dominant and homozygous recessive respectively. Homozygosity is the presence of two dominant alleles (AA) or two recessive alleles (aa).The recessive allele is suppressed by the dominant one.
What is heterozygous?The two distinct alleles in a heterozygous genotype interact with one another. This controls how their characteristics are shown. This encounter frequently centers on dominance. The stronger allele is referred to as "dominant," whilst the weaker allele is referred to as "recessive." The dominant allele covers up this recessive one.

A duplicated chromosome consists of two ______. A duplicated chromosome consists of two ______. genomes centrosomes centromeres sister chromatids
Answer:
The answer is chromatids.
Explanation:
A duplicated chromosome consists of two sister chromatids. Therefore, option (D) is correct.
A duplicated chromosome consists of two sister chromatids, which are exact copies of each other. During the S (synthesis) phase of the cell cycle, the DNA of a chromosome is replicated to produce two identical DNA molecules, and these two DNA molecules remain attached at a specialized region called the centromere. This attachment holds the sister chromatids together until they are separated during cell division.
When the cell enters mitosis (or meiosis), the duplicated chromosome condenses and becomes visible under a microscope. The sister chromatids are held together at the centromere, forming an X-shaped structure. During the process of cell division, the sister chromatids are pulled apart and distributed to the two daughter cells, ensuring that each cell receives an identical set of genetic information.
The presence of sister chromatids in a duplicated chromosome is essential for maintaining genetic stability and accurately transmitting genetic material from one generation of cells to the next. Therefore, option (D) is correct.

A neurotransmitter may have an excitatory or an inhibitory effect on the postsynaptic cell, depending on __________.
A neurotransmitter can have an excitatory or inhibitory effect on the postsynaptic cell, depending on which of its receptor(s) are present on the postsynaptic (target) cell.
How do excitatory and inhibitory neurotransmitters act?Sometimes neurotransmitters can bind to receptors and cause an electrical signal to be transmitted through the cell (excitatory). In other cases, the neurotransmitter can prevent the signal from continuing, preventing the message from being carried (inhibitory).
With this information, we can conclude that a neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.

Escherichia coli has a doubling time of 30 minutes. If a culture has 10 E. coli cells at the beginning of log phase, how many E. coli cells will be in the culture after two hours
80 E. coli cells will be in the culture after two hours.
What is culture?The development of the human, plant, or animal cells in a lab, as well as microorganisms like bacteria and yeast. Cell cultures can be used for research, medication testing, and infection diagnosis.
Primary (mortal) cultures and cultures of established (immortal) cell lines are the two main categories of cultures.
One of the most crucial methods in cellular and molecular biology is cell culture because it offers a platform for studying the biology, biochemistry, physiology, metabolism, and other aspects of both healthy and diseased cells.
A culture of 10 E. coli cells.
Incubation time = 2 hours = 120min
Doubling time = 30min (120/30 = 4)

If inhibiting thyroid hormone release with PTU (propylthiouracil) in an experiment, the experimental group receives PTU and the control group receives no PTU.
What is propylthiouracil (PTU) used for?The thyroid gland's ability to produce fresh thyroid hormone is inhibited by the drug propylthiouracil. It works by preventing the thyroid peroxidase enzyme from doing its normal job of converting iodide to an iodine molecule and incorporating that molecule into the amino acid tyrosine.PTU prevents iodine and peroxidase from forming T4 and T3 from reacting normally with thyroglobulin. Thyroid hormone synthesis is decreased by this action. Because T3 is more effective than T4 and PTU prevents T4 from being converted to T3, thyroid hormone activity is also decreased.An important factor in controlling body temperature is thyroid hormone. The body must rely more on shivering to regulate temperature in the absence of thyroid hormone. To generate ATP, additional oxygen must be used.To know more about thyroid here:

Is a type of weathering where rock is broken down as it absorbs water
Answer:
This is known as Mechanical Weathering.
Explanation:
Mechanical weathering is the process by which surfaces are degraded by interacting with something else, physically. Common methods of weathering are caused by wind, ice and water. Valleys are a distinct example of weathering and come in two types — “U” valleys and “V” valleys, so called because they are in the shape of those two letters.
How does mechanical and chemical weathering differ?
Erosion is the result of weathering (not the only one, but a major one). Chemical weathering is the result of interactions between a rock and its surroundings, often air or water. The elements in air and water can react with a rock's minerals to break them down into softer substances. Rocks that are exposed at the surface are therefore changed by these processes and become "weathered": their color is faded, their surface is softer, and they are crumbly (often). As iron-containing minerals oxidize, weathered rocks can take on a variety of red, orange, and yellow hues. Ice, for example, creates a lot of mechanical damage called physical weathering. When water freezes, it pushes the joint or crack farther apart, eventually causing the exposed rocks to break. Water seeps into joints and fissures in the rocks. Rocks are broken down by weathering and erosion into smaller and smaller pieces until soil is created or the smaller pieces may be carried by flowing water into streams and rivers, where they are sorted by size and redeposited as gravels, sands, and mud.
