The "essential nutrients" for proper human nutrition include _____. the "essential nutrients" for proper human nutrition include _____. calcium, sodium, potassium, and other minerals cellulose glucose active enzymes from plants and/or animals all of the amino acids

Answers

Answer 1
The correct answer is "calcium, sodium, potassium, and other minerals".
The term "essential nutrients" refers to the group of nutrients which are necessary for the normal functioning of human physiology but they cannot be synthesized by the human body. This means that these nutrients need to be obtained from external sources. This category of nutrients is comprised of some amino acids, two fatty acids, some vitamins and minerals.
Glucose and cellulose are not part of the essential nutrients. Also, only 9 of the 20 protein-producing amino acids cannot be synthesized by the human body and are therefore considered essential.
Answer 2
Final answer:

Essential nutrients, which individuals must obtain from their diet, include macronutrients like carbohydrates, proteins, and lipids, as well as micronutrients such as vitamins and minerals. These nutrients are vital for energy, building materials, and regulating body processes. The essential minerals include calcium, sodium, and potassium, among others.

Explanation:Essential Nutrients for Human Nutrition

The “essential nutrients” for proper human nutrition include a range of substances that the body requires but cannot synthesize in sufficient amounts. These nutrients must be obtained from the diet. They include macronutrients like carbohydrates, proteins (including all of the amino acids), and lipids (including essential fatty acids), as well as micronutrients such as vitamins and minerals. Among the essential minerals are calcium, sodium, and potassium. In contrast, cellulose and glucose are not categorized as essential nutrients, as cellulose is not digestible and glucose can be synthesized by the body. Likewise, while enzymes from plants or animals can be beneficial, they are not classified as essential nutrients. Certain vitamins, like vitamin D and vitamin K, are essential for functions such as maintaining a stable nervous system and assisting with blood clotting.

It is important to consume a balanced diet that provides all the essential nutrients. Major minerals are required in larger quantities than trace minerals but both are vital for overall health. Macronutrients are needed in larger amounts compared to micronutrients, which are still essential but needed in smaller quantities.

What is the Wernicke's area & does it affect your ability to speak?

Answers

Wernicke's area is the area of the brain responsible mostly for understanding language or speech comprehension but also for language development as well. It is located in the temporal lobe of the left brain. 

People with damage in the Wernicke's area have this so-called "expressive aphasia" wherein the patient can speak words and sentences, but these sentences are made up of mixed up, nonsensical words or "word salad". 

The Wernicke's area is intimately related to Broca's area, which is the area of the brain responsible for language and speech production, rather than comprehension.

Answers

Answer:

The answer is A i just took the test just Now.

Explanation:

Primary succession takes place over a long period of time on newly formed land, while secondary succession occurs quickly in areas that have disrupted by a natural disaster.

Primary succession takes place over a long period of time in an area that has been disrupted by a natural disaster, while secondary succession occurs quickly on newly formed land. The correct option is C.

What is Primary succession?

Primary succession refers to the process of the gradual growth of plant and animal communities on newly formed or exposed land.

Option A is incorrect because primary succession takes place over a long period of time on bare, previously uninhabited land, while secondary succession occurs on land that has already supported life and has been disturbed by a natural or human-caused event.

Option C is correct because primary succession occurs over a long period of time in an area that has been disrupted by a natural disaster, such as a volcanic eruption or glacier retreat, and typically begins with the establishment of pioneer species such as lichens and mosses.

Thus, the correct option is C.

Mendel performed a cross between individuals heterozygous for three different traits: green versus yellow seeds (green is dominant), red versus white flowers (red is dominant), and green versus yellow pods (green is dominant). what fraction of the offspring would have been expected to have green seeds, red flowers, and green pods?

Answers

Probability of Green seed * Red flowers * Green pods

3/4 * 3/4 * 3/4 =27/64

The fraction of offspring expected to have green seeds, red flowers, and green pods would be 27/64.

Assuming that the seed shape, flower color, and pod color are represented by A, B, and C alleles respectively.  

Since the parents involved in the cross are heterozygous for each trait, their genotypes would be AaBbCc each.

                 AaBbCc     x     AaBbCc

See the attached image for the Punnet's square analysis of the cross that results in the offspring with the phenotypic ratio.

(5.03 lc)the boxer crab, lybia tesselata, carries a small pair of anemones in its claws. when approached by a predator, it waves the anemones around, presenting the stinging tentacles and chasing away the predator. the anemones benefit by eating food particles from prey that the crab catches. what type of relationship is this?

Answers

I believe it's Mutualism

Answer:

Mutualism

Explanation:

Mutualism is the symbiotic association between two organisms in which both the partners are benefited. In the given example, the boxer crab uses the stinging tentacles of anemone to protect itself from the predators. On the other hand, the anemone is benefited by feeding on the particles from the prey caught by crab. Since both crab and anemone are benefited, it is an example of mutualism.

What do we know about heredity and sickle cell disease?
Sickle cell disease is the most common inherited blood disorder in the United States. Approximately 100,000 Americans have the disease.

In the United States, sickle cell disease is most prevalent among African Americans. About one in 12 African Americans and about one in 100 Hispanic Americans carry the sickle cell trait, which means they are carriers of the disease.

Sickle cell disease is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. Hemoglobin transports oxygen from the lungs to other parts of the body. Red blood cells with normal hemoglobin (hemoglobin-A) are smooth and round and glide through blood vessels.

In people with sickle cell disease, abnormal hemoglobin molecules - hemoglobin S - stick to one another and form long, rod-like structures. These structures cause red blood cells to become stiff, assuming a sickle shape. Their shape causes these red blood cells to pile up, causing blockages and damaging vital organs and tissue.

Sickle cells are destroyed rapidly in the bodies of people with the disease, causing anemia. This anemia is what gives the disease its commonly known name - sickle cell anemia.

The sickle cells also block the flow of blood through vessels, resulting in lung tissue damage that causes acute chest syndrome, pain episodes, stroke and priapism (painful, prolonged erection). It also causes damage to the spleen, kidneys and liver. The damage to the spleen makes patients - especially young children - easily overwhelmed by bacterial infections.

A baby born with sickle cell disease inherits a gene for the disorder from both parents. When both parents have the genetic defect, there's a 25 percent chance that each child will be born with sickle cell disease.

If a child inherits only one copy of the defective gene (from either parent), there is a 50 percent chance that the child will carry the sickle cell trait. People who only carry the sickle cell trait typically don't get the disease, but can pass the defective gene on to their children.





Sickle Cell Disease
An inherited disease in which the red blood cells have an abnormal crescent shape, block small blood vessels, and do not last as long as normal red blood cells. Sickle cell anemia is caused by a mutation (change) in a gene.




Woman's bane or wolf's bane is another term for which poison?

Answers

ACONITE

This is from a perennial herbaceous plant native to the mountain in the northern hemisphere. This plant grows well in moisture retentive but well draining soil in the mountain meadows. Death usually occurs within hours upon poisoning with usual symptoms of gastrointestinal such as nausea, vomiting, diarrhea. Others experience burning, tingling sensation and numbnes. In large dose of poisoning, motor weakness can be expected some hypotension, bradycardia, arrhythmia. Treatment is usually supportive and patients must be closely monitored.
Final answer:

Woman's bane or wolf's bane refers to Aconitum, a plant that produces a deadly poison. This can be related to Batesian mimicry, where a highly toxic species resembles a less toxic one, discouraging predators.

Explanation:

The term Woman's bane or wolf's bane is another name for the plant Aconitum, which produces a deadly poison. This fits under the concept of Batesian mimicry because it involves a highly toxic species (Aconitum) that resembles a lower toxic one. Batesian mimicry is when a harmless species imitates the warning signals of a harmful species to fend off predators. For instance, a plant like Aconitum might look visually similar to other less toxic plants, tricking potential predators into avoiding it due to the perceived risk of poisoning.

A large tract of land is purchased by a commercial agricultural company. The land is cleared of its native flora, and a single crop is planted instead. What is the effect of this action?

Answers

Final answer:

Clearing land for a single crop in commercial agriculture can result in the loss of biodiversity, changes in rainfall patterns, and increased vulnerability to pests and diseases.

Explanation:

When a large tract of land is purchased by a commercial agricultural company and cleared of its native flora to plant a single crop, it has several effects. One of the main effects is the loss of biodiversity as native plants and animals are displaced. This type of agricultural practice can also lead to changes in rainfall patterns and frequency and contribute to deforestation. Additionally, relying on a single crop can make the land more vulnerable to pests and diseases.

Bacitracin blocks the transport of nag and nam across the cytoplasmic membrane to the cell wall. like other antimicrobials that block cell wall synthesis, this would result in weak cell walls and __________.

Answers

The answer would be: cell lysis due to the effect of osmotic pressure
Cell membrane is important for microorganism because of it separate things outside cells and inside cells. This way, the cell can keep electrolyte and other useful things like carbohydrate and proteins. The cells also dump toxins and dangerous chemical that it produce outside the membrane so it won't damage organs inside the cells. 
Final answer:

Bacitracin inhibits the movement of peptidoglycan precursors, therefore interfering with cell wall synthesis and leading to weak cell walls. This results in bacterial cells being more susceptible to osmotic lysis, causing them to rupture due to a water concentration imbalance.

Explanation:

Bacitracin is an antibiotic that inhibits the movement of peptidoglycan precursors from the cytoplasm to the cell wall, interfering with cell wall synthesis in bacteria. Consequently, this results in the creation of weak cell walls and renders the bacterial cells more susceptible to osmotic lysis. This condition refers to the rupture or disintegration of the cell due to an imbalance in water concentration through the cell membrane. Osmotic lysis may occur in bacteria if too much water moves into the cell, causing it to burst. Essentially, bacitracin creates an environment in which it is difficult for bacteria to maintain their cellular structure, hence aiding in their elimination.

Answers

The question shows the results of a gel electrophoresis, which shows DNA fragments of the victim and two suspects, suspect 1 and suspect 2. A comparison of the five DNA fragments of the victim, A to E, reveals that the victim and suspect 1 both have the DNA fragment b.

A visual comparison of the gel electrophoresis results should reveal that Suspect 1 has a DNA fragment that matches victim DNA fragment B.The visuals can be seen in the attachment.

Final answer:

Without a visual reference, it's not definitive to say which DNA fragment is common between the victim and suspect 1. However, in DNA fingerprinting, common fragments are visible as aligned bands in the same position in both samples.

Explanation:

The process of identifying the DNA fragments in a sample is known as DNA fingerprinting. Without an image or graphical representation of the DNA fragments from the question, it's impossible to definitively say which fragments are common between the victim and suspect 1. However, in a typical DNA fingerprinting procedure, common fragments would be represented as bands in the same position in both the victim's and suspect 1's DNA samples.

This procedure is based on the concept of gene loci where each individual has unique DNA sequences. The comparison, in this case, is done by looking at the bands' positioning in each sample. If multiple bands, or even a single significant band, aligns between the victim and suspect 1, there could be a link suggesting that suspect 1 might be related to the crime scene.
