When an experiment is repeated and the new results are different from the original results, what could you assume to be true?
The original experiment may be inaccurate and further experimentation is needed.
The accuracy of measurements depends on the quality of the measuring equipment and the skill of the scientists involved. For the data to be considered reliable the variability of the values should be small. Repeated scientific research increases credibility. Results may change over the course of different studies or under different conditions.
It is therefore important that the experiment itself is reproducible. A reproducible experiment should but need not give the same results when performed by different people at different times and preferably under similar conditions. Repeating an experiment multiple times can help determine whether the data are random or normal. Avoid jumping to conclusions without sufficient evidence.

If you pinch your nose while you are putting a piece of food into your mouth, what are you going to experience?.
If you pinch your nose while putting food in your mouth, you may experience lack of taste in the food.
It did appear that smell had an impact. However, the ability to taste was not completely impaired by nose plugs. Chewing certain foods allows aromas to reach the nose through the back of the mouth even when the nostrils are closed because the nose and throat share essentially the same airway.
Molecules from your food travel up your throat to the olfactory epithelium, where they activate odor receptors, when you eat.
Retronasal olfaction, as opposed to orthonasal olfaction, which occurs when you sniff through your nose, is prevented by pinching your nose. Retronasal olfaction is very important to your sense of flavor, which many other people mistake for "taste.", we can demonstrate this with jelly beans: you can still taste the sweetness of the jelly bean by pinching your nose, but you can't tell the difference between a strawberry and a grape. One of the most common complaints made by people who have lost their sense of smell is that food no longer "tastes" good because it lacks a lot of flavor.

What is an advantage to the longer duration of cardiac action potential compared to the skeletal muscle action potential?.
Tetanic contraction is avoided by the longer duration of cardiac action potential, allowing the heart chambers to relax and fill with blood before the next contraction.
Compared to skeletal muscle, the refractory period of cardiac muscle is significantly longer. This avoids tetanus and guarantees that there is adequate time between each contraction for the heart chamber to fill with blood before the next one. Accordingly, cardiac muscle is benefitted with the longer duration of its action potential.
Similar to skeletal muscle, the influx of sodium ions results in an initial depolarization; however, the depolarization in cardiac muscle is sustained for a longer period of time thanks to the influx of calcium ions.

which of the following does not occur due to the effects of aging on the joints? select one: a. decreased range of motion b. decreased flexibility and elasticity c. increased production of synovial fluid d. weakening of muscles e. decreased tissue repair
Increased production of synovial fluid does not occur due to the effects of aging on the joints
Bones do not directly touch one another in a joint. They are padded by articular cartilage, which lines your joints, synovial membranes around the joint, and lubricating fluid inside your joints (synovial fluid). The amount of lubricating fluid inside your joints diminishes as you aging, and the cartilage gets thinner, making joint movement stiffer and less flexible. Joint stiffness is also often caused by the tendency of ligaments to shorten and lose some flexibility.
Lack of exercise is a major contributor to many of these joint changes that come with ageing. The fluid is kept moving by joint movement and the corresponding "stress" that comes with it. The cartilage contracts and stiffens with inactivity, decreasing joint mobility.

In glycolysis, a glucose molecule is split into two molecules of ______, and energy is harvested as atp and nadh.
A glucose molecule is split into two molecules of Pyruvate molecules.
An essential molecule in biology is pyruvate. It is a byproduct of the glucose metabolism process called glycolysis. One of two processes results in the breakdown of one glucose molecule into two pyruvate molecules, which are then used to produce further energy.
Pyruvate enters the citric acid cycle under aerobic conditions and proceeds through oxidative phosphorylation, which results in the net synthesis of 32 ATP molecules. Pyruvate is converted to lactate in anaerobic conditions by anaerobic glycolysis. During anaerobic respiration, two ATP molecules are produced.
The end product of glycolysis, an anaerobic process that breaks down glucose, is pyruvate. Pyruvate can be transformed into ethanol, the amino acid alanine, fatty acids or energy through acetyl-CoA, carbohydrates through gluconeo genesis, and fatty acids or energy.

The stage of cell division in a diploid organism if you see seven chromosomes, each consisting of a pair of sister chromatids meiosis II prophase. Option D.
Diploid cells have two complete sets of chromosomes. Most human cells are diploid and composed of 23 pairs of chromosomes for a total of 46 chromosomes. These are 22 pairs of autosomes and 1 pair of sex chromosomes. During telophase, sister chromatids become daughter chromosomes. Mitosis has five main stages prophase metaphase anaphase telophase, and cytokinesis.
Meiosis is the process by which diploid cells become haploid cells. The difference between haploid and diploid cells is that haploid cells contain one complete set of chromosomes, while diploid cells contain two complete sets of chromosomes. Meiosis involves the division of the diploid parent cell. When mitosis is complete, cells have two sets of 46 chromosomes, each surrounded by its own nuclear membrane.

If one nerve stimulus arrives at a muscle fiber so soon that the fiber has only partially relaxed from the previous twitch, the most likely result will be __________.
If one nerve stimulus arrives at a muscle fiber so soon that the fiber has only partially relaxed from the previous twitch, the most likely result will be paralyze.
What is nerve?The lag phase refers to the interval between a motor neuron's activation and the onset of muscle contraction (sometimes called the latent phase). A signal known as an action potential travels to the motor neuron's end during the lag period (axon terminal).
Acetylcholine is released as a result, and the motor end plate depolarizes. The sarcoplasmic reticulum releases calcium as a result of the depolarization, and calcium then binds to troponin, exposing the myosin binding site.
The actual muscular contraction that creates tension in the muscle occurs next. The contraction phase is the following stage. Actin and myosin cross-bridges form during the contraction phase. Actin is moved by myosin, which also releases and modifies cross-bridges.
Therefore, If one nerve stimulus arrives at a muscle fiber so soon that the fiber has only partially relaxed from the previous twitch, the most likely result will be paralyze.

(30)Can an organism with a homozygous dominant genotype have an offspring with the recessive phenotype? Explain your answer
(in depth explanation pls ;-;)
No, an organism with a homozygous dominant genotype cannot have an offspring with the recessive phenotype because when crossed with hetero/ homozygous , the offspring will contain a dominant allele.
What is a genotype?An individual's genotype, often known as their genetic make-up, refers to the genes that are responsible for a set of characteristics or qualities that are manifested in that individual.
The phenotype is the outward manifestation of how a gene is expressed. The phenotype is the sum total of all the genes in an individual that are either expressed or can be observed in their physical form.
It is only possible for the phenotype associated with recessive alleles to be expressed in an organism if that organism possesses two copies of the recessive allele, making it homozygous for the recessive allele. This indicates that the genotype of an organism that possesses a dominant phenotype might either be homozygous for the dominant allele or heterozygous for the dominant allele.
Therefore, an organism with a homozygous dominant genotype cannot have an offspring with the recessive phenotype.
