Chloroplasts are like solar panels because chloroplasts convert the sun’s energy into energy that can be used by cells like solar panels convert the sun’s energy into energy that can be used by a house. Golgi Apparatus- site where proteins are further processed for shipment out of the cell.

The cytoplasm does the same thing for it’s cell. The Cell Membrane can be represented as the skin of the human body. This is because the skin is the outer part of the body and it can control what gets in the body and what stays out, just like what the cell membrane does for the cell.

Your cells are the energy converters for your body. Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue.

The Golgi body helps to create and package large molecules used in other parts of the cell. This organelle is found in both plant and animal cells. the equivalent in the human body is the blood veins.

This article will discuss the histology of most important types of cells in the human organism.

• Stem cells.
• Red blood cells.
• White blood cells. Neutrophils. Eosinophils. Basophils. Lymphocytes.
• Platelets.
• Nerve cells.
• Neuroglial cells.
• Muscle cells. Skeletal muscle cells. Cardiac muscle cells. Smooth muscle cells.
• Cartillage cells.

Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

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.

Human skin is made of several layers of cells. A person sheds 400,000 skin cells a day, but that’s dead skin on the top layer. The skin underneath the shedding layer is what contains the DNA.

There is typically a lack of DNA in our mature red blood cells and cornified cells which are found in hair, skin, and our nails. These cells don’t contain a nucleus. It turns out, our red blood cells are actually trained to destroy their cells nuclei.

Where Is DNA Contained in the Human Body? DNA is contained in blood, semen, skin cells, tissue, organs, muscle, brain cells, bone, teeth, hair, saliva, mucus, perspiration, fingernails, urine, feces, etc.

If we could zoom in on a single, tiny cell, we could see an even teenier “container” inside called a nucleus. It holds a stringy substance called DNA, which is like a set of blueprints, or instructions. Just like us, banana plants have genes and DNA in their cells, and just like us, their DNA determines their traits.

The chimpanzee and bonobo are humans’ closest living relatives. These three species look alike in many ways, both in body and behavior. But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that’s the instruction manual for building each species.

More startling is an even newer discovery: we share 99% of our DNA with lettuce.

We know chimps and bonobos share 99% of our genes. More startling is an even newer discovery: we share 99% of our DNA with lettuce.

Buzzing right around, bees share about 44 percent of human DNA. We share about 26 percent of our “housekeeping” genes with these single-cell organisms. We share approximately 15 percent of our DNA with this plant.

According to calculations by geneticist Graham Coop of the University of California, Davis, you carry genes from fewer than half of your forebears from 11 generations back. Still, all the genes present in today’s human population can be traced to the people alive at the genetic isopoint.

There has been inbreeding ever since modern humans burst onto the scene about 200,000 years ago. And inbreeding still happens today in many parts of the world. Since we are all humans and all share a common ancestor somewhere down the line, we all have some degree of inbreeding.

The Donnellys, the world’s oldest family, have more than 1,000 years of life among them. The 13-sibling farming family from rural County Armagh, Ireland, recently received a Guinness World Record for being the oldest living siblings.

To be more specific:

1. Research all your family surnames carefully.
2. If you find records indicating where your ancestors lived, look up those residences and see if they are associated with royalty.
3. Search for your family members in record collections that are specific to nobility and other notable historical figures.

Type O’s are the purest, especially O negatives, the universal donors. They have the purest blood, or what Europeans used to call “royal blood”. The positive and negative signs in your blood type are also very crucial as they denote whether you have or lack the RhD Antigen (Rhesus) factor.

AB

Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.

There are a few differences, starting with the presence of a cell wall. The most characteristic feature of plant cells is their rigid cell wall. Human cells only have a cell membrane. The cell wall is primarily made of cellulose, which is composed of glucose monomers.

Nothing is more important to us on Earth than the Sun. Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

Without enough vitamin D, the body can only absorb 10% to 15% of dietary calcium, but 30% to 40% absorption is the rule when vitamin reserves are normal. A lack of vitamin D in children causes rickets; in adults, it causes osteomalacia.

The sun is the closest star to Earth. It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce.

NASA cameras have captured video of the largest explosion it has ever seen on the moon… ‘For about one second, the impact site was glowing like a fourth magnitude star,’ NASA said. The meteoroid was traveling around 56,000 miles per hour when it slammed into the moon’s surface.

The project was never carried out, being cancelled after “Air Force officials decided its risks outweighed its benefits”, and because a Moon landing would undoubtedly be a more popular achievement in the eyes of the American and international public alike.

The gravity from Luna would tug on the Earth; causing large tsunamis with the rise and fall of the tides more often than they currently occur, and an increase in earthquakes (look out California!), and an increase in volcanic activity, which would pump ash and carbon dioxide into the atmosphere.

In 2010, NASA Lunar Science Institute (NLSI) staff scientist Brad Bailey said, “No current scientific evidence reports that the Moon was split into two (or more) parts and then reassembled at any point in the past.”

It’s the interplay of gravity between Earth and the moon that has given us the 24-hour day. So if the moon were bigger, we’d probably rotate even more slowly and have an even longer day. We can also get an idea of what a bigger moon would be like by looking at other planets in our solar system. Take Pluto.

The migration of the Moon away from the Earth is mainly due to the action of the Earth’s tides. The Moon is kept in orbit by the gravitational force that the Earth exerts on it, but the Moon also exerts a gravitational force on our planet and this causes the movement of the Earth’s oceans to form a tidal bulge.

Calculations of the evolution of the Earth/Moon system tell us that with this rate of separation that in about 15 billion years the Moon will stop moving away from the Earth. Now, our Sun is expected to enter its Red Giant phase in about 6 to 7 billion years.

The Moon will swing ever closer to Earth until it reaches a point 11,470 miles (18,470 kilometers) above our planet, a point termed the Roche limit. “Reaching the Roche limit means that the gravity holding it [the Moon] together is weaker than the tidal forces acting to pull it apart,” Willson said.

It may change the color of the moon, depending on how particles bend and filter moonlight, but that’s about all it does. That changes by a minuscule amount between lunar cycles, with the moon’s apparent size getting up to 14 percent larger than normal during its closest approach to Earth.

“When the moon is near the horizon, the ground and horizon make the moon appear relatively close. Because the moon is changing its apparent position in depth while the light stimulus remains constant, the brain’s size-distance mechanism changes its perceived size and makes the moon appear very large.

Between different full moons, the Moon’s angular diameter can vary from 29.43 arcminutes at apogee to 33.5 arcminutes at perigee—an increase of around 14% in apparent diameter or 30% in apparent area. This is because of the eccentricity of the Moon’s orbit.

When it’s a Full Moon, it rises at sunset. When the Sun rises in the early morning, the Full Moon sets. This is the only phase when the Moon is in the sky all night. The Moon starts to fade again.

One of the more obvious reasons is weather conditions. If there are a lot of clouds in place, naturally, this will mean we won’t see the moon. However you may notice the light behind the clouds. Some of the other reasons that you may not see the moon is due to it’s position in the sky and the moon’s phase.

In the daytime we see the sun shine. Our sun is a very bright star. The sun’s bright light blocks out other stars. It blocks out stars that are not as bright.
