Jamal ate a meal of rice before seeing his doctor. Rice is made of mostly starch molecules. Jamal has been feeling tired a lot, so his doctor gave his a test that found jamal’s cells contained normal levels of oxygen and low levels of glucose. Does this explain why Jamal has been feeling tired
Answers
Answer:
Yes, Jamal’s respiratory system is working, but his digestive system is not breaking down starch molecules into glucose for his cells.
Explanation:
Jamal ate a meal of rice before seeing his doctor. Jamal has been feeling tired because his body cannot breakdown the starch molecules into glucose and thus has low levels of glucose in the blood.
What is a healthy diet?
A healthy diet is a diet which maintains or improves the overall health of an individual. A healthy diet provides the body with all the essential nutrients in sufficient amount. A healthy diet contains fluids, macronutrients such as protein, micronutrients such as vitamins with adequate amount of fiber and food energy.
Jamal is eating a meal of rice before seeing the doctor. He is feeling tired. After the test, it was observed that the oxygen level is normal however he has a low level of glucose. This is because rice contains high amount of starch, which is a polysaccharide of glucose. This starch is broken down by the body into glucose units which are used by the cells in producing energy. However, Jamal's body cannot break down this starch into glucose molecules and thus show low levels of glucose molecules.

Alana summarized what happens when a ball sitting on top of a grassy hill rolls down the hill.
The motionless ball has potential energy. Once the ball starts to roll down the hill, new kinetic energy is made. As the ball rolls across the grass, it slows down. The kinetic energy of the ball is converted to other forms of energy.
Which best describes Alana’s error?
The motionless ball does not have energy because it is still.
Kinetic energy is not made; it is a result of energy transformation.
The ball cannot slow down unless someone touches it.
The energy is not converted; it disappears.
Answers
Answer:
It's actually B that guy is wrong on Edge.
Explanation:
Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.
What are the various types of energy?The law of conservation of energy says that energy is neither created nor destroyed but only converted from one form to another, such as from the kinetic to the potential and vice versa. Here, the ball is placed at the top, where it has no motion, but the ball has potential energy, and that potential energy gets converted into kinetic energy when the ball starts to roll down the hill. After sometime, the ball spontaneously stopped on the ground, and the kinetic energy was converted into potential energy.
Hence, Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

Describe the control group for an experiment that examines the effect of fire intensity on the biodiversity of tree communities.
Answers
Answer:
explanation below
Explanation:
The control group would be the biodiversity of the trees without the fire
The control group in the experiment would center on the biodiversity of the trees without the fire. Ideally, both the control group and the experimental groups are usually identical in every way except that the experimental group would receive the treatment that is believed to have an effect on the biodiversity of trees.
For an experiment seeking to study the effect of fire intensity on the biodiversity of tree communities, the control group will be an experimental unit consisting of a community of biodiversity of trees with no fire or treatment.
In a scientific experiment, they are usually two main groups of experimental units. They are:
The Experimental Group: This group of experimental units receive the treatment. In the case of the experiment cited above, the experimental group would be a community of biodiversity of trees that is set on fire.The Control Group: This experimental units do not receive treatment. They serve as the basis for comparison. In the scenario cited in the question, the control group would be a community of biodiversity of trees without the treatment, which is, no fire on the community.Therefore, for an experiment seeking to study the effect of fire intensity on the biodiversity of tree communities, the control group will be an experimental unit consisting of a community of biodiversity of trees with no fire or treatment.

what type of igneous rocks are the Hawaiian islands
Answers
The Hawaiian Islands are nearly entirely made of basalt lava, the most abundant type of rock on the planet.
What is igneous rock and its type ?Hot, molten rock crystallizes and hardens to produce igneous rocks, which are named after the Latin word for fire. The melt begins deep inside the Earth around hot regions or active plate borders, then it rises toward the surface. Depending on where the molten rock hardens, igneous rocks are classified as either intrusive or extrusive.
Intrusive Igneous Rocks: When magma is imprisoned in the Earth's interior, intrusive, or plutonic, igneous rocks are created. The individual mineral grains have a very long time to develop because of the slow cooling, and as a result, they reach a comparatively enormous size. Rocks that are intrusive have a coarse-grained texture.Extrusive Igneous Rocks: When magma escapes and cools above (or very close to) the Earth's surface, igneous rock known as extrusive rock is created. These are the kinds of rocks that are created by erupting volcanoes and gushing cracks.
These rocks have an extremely fine-grained or even glassy structure because of the rapid cooling, which leaves little time for mineral crystals to develop. The quenched lava frequently contains trapped hot gas bubbles, giving it a frothy, vesicular texture.
Thus, Hawaiian islands are made up of basalt ; the most common rock on the earth.

How does a stem cell become specialized into a heart cell?
Answers
Answer:
Explanation:
stem cells are manipulated to specialize into specific types of cells, such as heart muscle cells, blood cells or nerve cells. The specialized cells can then be implanted into a person. For example, if the person has heart disease, the cells could be injected into the heart muscle.
Daughter cells are created when stem cells divide properly in the body or a lab to create more cells. These daughter cells either develop into fresh stem cells or into differentiated cells with a more specific role, such as bone, blood, brain, or heart muscle cells.
How are stem cells differentiated?According to research, cardiomyocytes made from pluripotent stem cells can develop into beating human heart muscle cells that both produce the required signals and restore muscle lost during a heart attack.
Stem cells have the ability to multiply and develop into a variety of relatively mature cells. When inserted into a blastocyst, embryonic stem cells have the ability to develop into any organ in the human body.
Therefore, theoretically, every organ in the body might be replaced using embryonic stem cells.

Which is not a function of the respiratory system? *
It warms air entering the body.
O It exchanges oxygen and carbon dioxide.
O It pumps blood to the organs.
O It creates sound through the voice box.
Answers
Answer:
it exchanges oxygen and carbon dioxide
Explanation:
You inhale oxygen and exhale carbon dioxide
Out of the given options 3 that is "it pumps blood to the organs" is not a function of the respiratory systems.
The respiratory system is a network of organs and tissues that assist you in breathing. This system assists your body in absorbing oxygen from the air so that your organs can function.
It also removes waste gases from your blood, such as carbon dioxide. Allergies, illnesses, and infections are common difficulties.
The respiratory system contributes to the warming and humidification of the air we breathe. The air is warmed as it goes through the nasal passages and pharynx, which helps to protect the lungs' sensitive tissues.
The respiratory system contributes to the production of sound. When air flows through the larynx (voice box), the vocal cords vibrate, producing sound.
Thus, the option 3 is not the function of the respiratory system.

W Within a forest ecosystem, there is a large amount of diversity among members of a warbler species. Of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers? Pay special attention to the chromatids.
Answers
Answer:
Explanation:
How a Forest Ecosystem Matures . Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving toward an old growth forest.
A Large amount of warbler species, crossing over between homologous chromosomes, is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.
There are different mechanisms involved in producing genetic variation among descendants, are-
Crossing-over between homologous chromosomes (prophase 1), The Random lining of homologous chromosomes (metaphase 1), Random fertilization
The Crossing-over events occur between two homologous chromosomes within the equatorial plane and make the daughter cells genetically different from the first one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving an area for brand spanking new genetic material or information to be provided to descendants.
After crossover, homologous chromosomes get separated again. In the attached image there are four different stages of meiosis.
Stage C is the one that contributes foremost to diversity. We can see that crossover has already occurred between homologous chromosomes and that they have already interchanged segments.
In the image, you will see the difference between chromosomes that have gone through the crossing over mechanism, and chromosomes that have not. The difference in color represents segments interchange and variation.
Therefore, that answer shows the contribution to diversity among the warblers.
