what do you think will happen when i put a leaf discs saturated with a sodium bicarbonate solution and put it under a lamp ? will it sink or float and why ? can someone help me rq will give 30 points
Answer:
the leaf disk should float because bicarbonate is the source of its oxygen for photosynthesis and it releases oxygen into the interior of the disk causing it to float.
Explanation:
The thing which would happen if leaf discs are saturated with a sodium bicarbonate solution and put under a lamp is:
The leaf disk would floatAccording to the given question, we can see that there is an experiment which is taking place as a leaf disc is placed in a solution of sodium bicarbonate under a lamp.
As a result of this, we can see that the source of oxygen for the leaf disk is the bicarbonate and when the chlorophyll in the plant reaches out to the lamp for photosynthesis, it would make the leaf disk to float.

You have a friend who became stranded in a blizzard without food for
several weeks. This friend, when rescued, had lost about 7 kg (about 15
Ibs). As he was quite healthy to begin with, he assumed the weight he
lost was stored fat, but he wondered where the fat had gone, How did
the fat leave his body?
The fat didn't really leave his body. Fat was converted to glucose in the gluconeogenesis pathway to give him energy during the period of starvation.
Fat is stored in the body in the adipose tissue. Fat plays so many roles in the body such as;
Protection of vital organsInsulating the body from coldServing as an energy storeIn times of starvation, fact could also be broken down to release energy. This occurs when fat is broken down to glycerol and fatty acids. When this occurs, glycerol goes to the liver where it is converted to glucose in the gluconeogenesis pathway. This helps to produce energy in times of starvation thereby depleting the body's fat reserve.
As this process occurs, the fat reserve in my friend's body kept going down resulting in his loss of about 15 Ibs of weight.

Looking for input and other opinions with the following statement. 'environmental factors influence the rate of natural selection." I am to make a claim on whether I agree or not and why. I agree with the statement. This is because all literature states that with natural selection it's basically the best man/woman wins. I feel that with that statement it directly refers to the environment if food is scarce then the best hunter the best runner is going to get the food first if the weather is changing and it's time to move on or hibernate then the one with the best intuitions will move on or assume hibernation and wont be left to the cold as well as if they are the prey to something else as everything is the best one to keep alert and observant to their surrounding would be the one to survive longer. Although I think that the only downfall to that would be if something happened and the appearance was to change and made them less desirable in that manner but then would in turn help themselves to camouflage to hide better.
I agree completely.
Environmental factors control evolution through surivial of the fittest, or natural selection. This is not nearly as much the case with humans as wild animals, or early on humans, but it does still come into play. For example, lactose intolerance was erradicated in areas where milk was a primary source of nutrients during a famine. The famine was environmental, causing natural selection to elimate lactose intolerant people in the area.
A more basic example is fur color of certain animals. They were selected by their environment to survive and pass on their genetics, causing the species to evolve.

How are the shapes of red blood cells and the shapes of nerve cells related to their functions? Thank you!
Answer:
How is the shape and size of red blood cells related to their function?
This biconcave shape allows the cells to flow smoothly through the narrowest blood vessels. Gas exchange with tissues occurs in capillaries, tiny blood vessels that are only as wide as one cell. Many RBCs are wider than capillaries, but their shape provides the needed flexibility to squeeze through.

Marine biologists have determined that when a shark detects the presence of blood in the water, it will swim in the direction in which the concentration of the blood increases most rapidly. Based on tests conducted by the biologists, the concentration of blood (in parts per million) at a point P(x,y,z) on the surface of sea water is approximated by
Blood concentration is approximated by the distance from the source.
The concentration of blood at a point P(x,y,z) on the surface of sea water is approximated by the distance from the source where the blood moves. Point x is the place where the concentration of the blood is the highest because at this point the source of blood present.
At point y, the concentration of the blood is lower as compared to point x but higher than point z, while on the other hand, at point z the concentration of blood is the lowest due to its presence farther from the source so we can conclude that blood concentration is approximated by the distance from the source.

A nucleus is a membrane-bound structure. A nucleoid is not surrounded by a membrane.
5 organelle cells not found in human cells
Hurry homework due in couple minutes
Answer:
Not every cell in the human body contains DNA bundled in a cell nucleus. Specifically, mature red blood cells and cornified cells in the skin, hair, and nails contain no nucleus. Mature hair cells do not contain any nuclear DNA. ... As part of the maturation process, human red blood cells destroy their cell nuclei.
This means they have no mitochondria, Golgi apparatus, or endoplasmic reticulum. They also lack a membrane-bound nucleus, although they do have genetic material located in a nucleoid region. Prokaryotic cells are surrounded by a plasma membrane, and some types of bacteria have cell walls as well.
Nucleolus. Within the nucleus is a small subspace known as the nucleolus. It is not bound by a membrane, so it is not an organelle. This space forms near the part of DNA with instructions for making ribosomes, the molecules responsible for making proteins.

Myths, misunderstandings, and negative stereotypes and attitudes surround mental illness. These result in stigma, discrimination,and isolation of people with mental illness, as well as their families and carers.
----------------------------------------------------------------------------------------------------------------
Are mental illnesses a form of intellectual disability or brain damage?
No. They are illnesses just like any other, such as heart disease, diabetes, and asthma. Yet the traditions of sympathy, support, and flowers given to people with physical illnesses are often denied to those with a mental illness.
Are mental illnesses incurable and lifelong?
No. When treated appropriately and early, many people recover fully and have no further episodes of illness.
For others, mental illness may recur throughout their lives and require ongoing treatment. This is the same as many physical illnesses, such as diabetes and heart disease. Like these other long-term health conditions, mental illness can be managed so that individuals live life to the fullest.
Although some people become disabled as a result of ongoing mental illness, many who experience even very major episodes of illness live full and productive lives.
Are people born with a mental illness?
No. A vulnerability to some mental illnesses, such as bipolar mood disorder,can run in families. But other people develop mental illness with no family history.
Many factors contribute to the onset of a mental illness. These include stress, bereavement, relationship breakdown, physical and sexual abuse, unemployment,social isolation, and major physical illness or disability. Our understanding of the causes of mental illness is growing.
Can anyone develop a mental illness?
Yes. In fact, as many as one in five Australians may develop a mental illness at some stage in their lives. Everyone is vulnerable to mental health problems.
Many people feel more comfortable with the notion of having 'a nervous breakdown' rather than a mental illness. However, it is important to talk openly about mental illness, as this reduces the stigma and helps people to seek early treatment.
Are people with mental illness usually dangerous?
No. This false perception underlies some of the most damaging stereotypes. People with a mental illness are seldom dangerous. Even people with the most severe mental illness are rarely dangerous when receiving appropriate treatment and support.
Should people with a mental illness be isolated from the community?
No. Most people with a mental illness recover quickly and do not even need hospital care. Others have short admissions to hospital for treatment. Improvements in treatment over recent decades mean that most people live in their communities, and there is no need for the confinement and isolation that was commonly used in the past.
A very small number of people with mental illness need hospital care,sometimes against their will. Improvements in treatment are making this less and less common, and fewer than one in a 1000 people are treated this way.
