The Amazing World Inside a Human Cell
By Alisa Machalek and Emily Carlson
Posted June 29, 2011
Let's take a quick trip inside to see how cells carry out their major tasks.
Imagine you've shrunk down to 3 millionths of your normal size and are now about 0.5 micrometers tall—way
smaller than a dust mite or the width of a hair strand. At this scale, a medium-sized human cell looks as big as
a football field.
Nucleus
From your new perspective, the cell's somewhat spherical nucleus catches your
attention. It looks about 50 feet wide. Occupying up to 10 percent of the cell's
interior, the nucleus is the most prominent organelle, or cellular compartment. It
contains the cell's genetic material, DNA, which guides the making of billions of
protein molecules that participate in nearly every cellular process.
Membranes
The double membrane that bounds the nucleus flows into the ribosome-studded rough endoplasmic reticulum
(purple). Proteins are processed and lipids are manufactured in the smooth endoplasmic reticulum (blue) and
Golgi apparatus (green). Credit: Judith Stoffer, jStoffer Medical Illustration.
Encasing the cell is a membrane with special gates, channels and pumps that let in or
force out selected molecules. The membrane protects the cell's internal
environment—a thick brew called the cytosol made of salts, nutrients and proteins

Answer: What Is a Real Hypothesis?
A hypothesis is a tentative statement that proposes a possible explanation to some phenomenon or event. A useful hypothesis is a testable statement, which may include a prediction. A hypothesis should not be confused with a theory. Theories are general explanations based on a large amount of data. For example, the theory of evolution applies to all living things and is based on wide range of observations. However, there are many things about evolution that are not fully understood such as gaps in the fossil record. Many hypotheses have been proposed and tested.
When Are Hypotheses Used?
The key word is testable. That is, you will perform a test of how two variables might be related. This is when you are doing a real experiment. You are testing variables. Usually, a hypothesis is based on some previous observation such as noticing that in November many trees undergo color changes in their leaves and the average daily temperatures are dropping. Are these two events connected? How?
Any laboratory procedure you follow without a hypothesis is really not an experiment. It is just an exercise or demonstration of what is already known.
How Are Hypotheses Written?
Chocolate may cause pimples.
Salt in soil may affect plant growth.
Plant growth may be affected by the color of the light.
Bacterial growth may be affected by temperature.
Ultra violet light may cause skin cancer.
Temperature may cause leaves to change color.
All of these are examples of hypotheses because they use the tentative word "may”. However, their form is not particularly useful. Using the word “may” does not suggest how you would go about providing supporting evidence for the hypothesis. If these statements had not been written carefully, they may not have even been hypotheses at all. For example, if we say "Trees will change color when it gets cold." we are making a prediction. Or if we write, "Ultraviolet light causes skin cancer." could be a conclusion. One way to prevent making such easy mistakes is to formalize the form of the hypothesis.

Coral animals survive best in warm water. Which material is most abundant in warm water?
carbon dioxide
oxygen
nitrogen
Nitrogen are the most abundant in warm water in which coral animals survive best. So, the correct options is C.
What are Coral animals?Corals are creatures. The branch or pile we commonly refer to as "a coral" is actually a collection of countless microscopic creatures called polyps. An invertebrate called a coral polyp can range in size from the size of a pinhead to as much as one foot in diameter. Corals prefer the warmer waters of the tropics since they cannot survive in water that is below 18 degrees Celsius.
Nonetheless, since they do not produce their own food like plants do, corals are considered to be animals. Corals have small arms that resemble tentacles that they employ to scoop food out of the water and into their mysterious mouths. In warm water, where coral animals thrive, nitrogen is most prevalent.
Therefore, the correct options is C.

Which student correctly identified the geological process that formed Himilayan mountains?
Answer:
Student 2 is correct!
Explanation:
The Himalayas, which stretch over 2400 km between the Namcha Barwa syntaxis in Tibet and the Nanga Parbat syntaxis in Kashmir, are the result of an ongoing orogeny — the result of a collision of the continental crust of two tectonic plates. This immense mountain range was formed by tectonic forces and sculpted by weathering and erosion.
The geological events include the formation of the mountains. Student 2, stated about the collision of the continental plates. Thus, option A is correct.
What are continental plates?Continental plates are the plate tectonics that is found between the crust and the mantle of the earth (lithosphere). The continental plates are said to have less density than the oceanic plates. This results in the formation of the elevation unlike the depression in oceans.
The converging of the continental plates resulting from collision causes the crust to uplift and form the Himalayan mountains. The tectonic plate of the continents melts, slides, and falls against each other to form the elevated structure.
Therefore, option A. student 2 correctly explained the Himalayan mountain formation.

What would be a possible disadvantage of asexual reproduction?
Ability to reproduce in the absence of a mate
Results in low genetic variation of the species
Allows for more genetic variation in the offspring
Takes less time to produce offspring
A possible disadvantage of asexual reproduction is that it results in low genetic variation of the species. Since asexual reproduction involves a single parent, the genetic material of the offspring is identical to that of the parent.
What is the meaning of the advantageous mutations ?
This means that any advantageous mutations or adaptations that could arise from sexual reproduction and genetic recombination will not occur in the offspring.
Low genetic variation can make a species more vulnerable to environmental changes or disease outbreaks, as there is less genetic diversity to help the species adapt and evolve.
Additionally, asexual reproduction can also increase the risk of genetic disorders and diseases. With sexual reproduction, there is a mixing of genetic material from two different individuals, which can help to weed out harmful mutations.
However, in asexual reproduction, any harmful mutations in the parent's DNA will be passed down to the offspring without any opportunity for them to be removed or diluted through genetic recombination.
Finally, asexual reproduction can lead to the accumulation of deleterious mutations over time. Since there is no genetic recombination in asexual reproduction, mutations that are not necessarily harmful in a heterozygous individual can accumulate over time, leading to the expression of harmful recessive alleles in homozygous individuals.
This can reduce the overall fitness of the species and make it more vulnerable to environmental pressures.

which kind of soil is likely to have the HIGHEST porosity? A) Soil that is a mixture of sand and clay. B) soil that is all clay. C) soil that is a mixture of silt and clay. D) soil that is all sand.
Explanation:
Sand have the largest particle size so it has the highest porosity.
The answer is Soil that is all sand (D).
Soil that is all sand is likely to have the HIGHEST porosity. Therefore option D is correct.
Porosity refers to the amount of empty space or voids within a soil or rock. It is a measure of how much water or air can be stored in the soil. The type and arrangement of soil particles greatly influence porosity.
Sand particles are relatively large and have larger spaces between them compared to clay or silt particles. This means that sand has a higher porosity because it has more empty spaces or voids that can hold water and air.
The larger particle size allows for better drainage and easier movement of water and air through the soil.
In contrast, clay particles are much smaller and tightly packed together, resulting in smaller spaces between them. This compact arrangement reduces the porosity of clay soils, making it harder for water and air to penetrate and move through the soil.
Soil that is a mixture of sand and clay may have a moderate porosity, as the sand particles contribute to higher porosity while the clay particles reduce it to some extent. Similarly, soil that is a mixture of silt and clay may also have moderate porosity.
Therefore, if we consider the given options, soil that is all sand is likely to have the highest porosity due to the larger particle size and the resulting larger spaces or voids between the sand particles.

Explanation:
In 2000, Bob Harmon discovered the best-preserved Tyrannosaurus rex skeleton ever found. The fossilized dinosaur was sticking out of the wall of a canyon in Montana. Many scientists were eager to study the fossils.
Dr. Mary Schweitzer got one of the leg bones to analyze. Dr. Schweitzer’s assistant dissolved the bones in acid and discovered that some soft tissue had survived even after 68 million years. The discovery was a shock to the scientific community. No one had ever found such old tissues.
Next, Dr. Schweitzer looked for evidence of proteins in the T. rex tissues. She matched several samples from the fossil to parts of the modern protein collagen. Dr. Schweitzer’s discovery was so revolutionary that very few scientists believed her results. She repeated the experiment several times with great care. Each time she got the same results. In 2017, the scientific community finally accepted that proteins really could survive intact for 68 million years.
