After being hit in the back of the head by a beer bottle during a bar fight, John was dazed and could not see for about two minutes. Which lobes of his brain were affected? a. Frontal lobes b. Parietal lobes c. Temporal lobes d. Occipital lobes

Answer;

The same results are expected each time the experiment is done.

If an experiment exhibits reproducibility it means the same results are expected each time the experiment is done.

Explanation;

Reproducibility is the ability of other people to produce the same results from a given experiment under the same conditions, and without the influence of unanticipated factors.

Reproducibility is an important aspect of science, this is because it ensures transparency and gives us confidence in understanding exactly what is done.

Cells were first observed through a simple microscope, which is the first option, as Antonie van Leeuwenhoek, a Dutch scientist, used a simple microscope that he designed and built himself to observe and describe microscopic organisms.

What is a microscope?

The history of the microscope goes back several centuries, with various scientists and inventors contributing to its development. One of the most notable figures in the history of microscopy is Antonie van Leeuwenhoek, who is considered the father of microbiology. He was a Dutch tradesman and amateur scientist who lived in the 17th century, and he was the first person to observe and describe microscopic organisms. Leeuwenhoek's microscope was a simple microscope, which means that it had only one lens. The lens was a small, spherical bead of glass that was mounted on a metal plate. 

Hence, cells were first observed through a simple microscope, which is the first option.

Answer:

Simple microscope

Explanation:

Answer: Proteins

Actin belongs to a family of globular multifunctional protein and myosin is a belongs a family of motor proteins. Both actin and myosin combines to form microfilaments. These are found in the eukaryotic cells. In humans and animals the combination of actin and myosin is responsible for contraction and relaxation of muscles in the presence of ATP.

Final answer:

Actin and myosin, which are primarily found in muscle cells, are macromolecules made up of proteins. These proteins are critical in muscle movement and function.

Explanation:

Actin and myosin are made up of proteins. Proteins are one of the macromolecules vital for building and repairing tissue. In the context of muscle cells, actin and myosin play a pivotal role. They interact to cause muscle contraction, a process vital for movement. Actin is a thin filament while myosin is a thicker one, and they slide past each other to cause the contraction of the muscle. Therefore, proteins have a substantial role in muscle movement and function.

Answer is "0.04 Population"

Explanation:

• The human body is a remarkable piece of work in which every part has its own function. Each part has a specific structure to best fit its function. When everything is structured (shaped) properly, it should function properly. However, there are many times when parts of the body are misshaped, and the deformed structure no longer allows for the body to function properly
• The function, or job, of red blood cells is to carry oxygen to all the organs in the body. They also get rid of the carbon dioxide (CO2), a poison in our bodies. They travel through a maze of blood vessels such as veins and arteries. To make for smooth travel through the body, normal red blood cells are shaped like little flexible disks. Their shape allows for them to bend and twist and move around the body in a smooth, fluid movement. Blood cells shaped like sickles can obviously not perform their function as well
• All red blood cells have a protein in them called hemoglobin (HEE-muh-glow-bin). Hemoglobin is what attaches the oxygen to the cell. A person with sickle cell anemia has some red blood cells that have a different kind of hemoglobin called hemoglobin S. Hemoglobin S causes a red blood cell to be deformed into a sickle shape. A sickle cell is stiff and sticky instead of smooth and flexible
• Hence the right answer is "0.04 proportion of population should be susceptible to sicle-cell anemia inder typical condition"

The heat or energy that Earth receives from the sun is primarily absorbed by its surface and atmosphere. Some of the absorbed energy is re-radiated back to space as infrared radiation, while some of it is trapped by greenhouse gases in the atmosphere.

What is solar radiation?

The sun radiates energy in the form of electromagnetic radiation, which includes visible light, ultraviolet radiation, and infrared radiation. When this radiation reaches the Earth's atmosphere, a small fraction of it is reflected back to space, while the rest is absorbed by the Earth's surface, including the land, oceans, and atmosphere. Once absorbed, the energy is transformed into heat, which causes the surface and atmosphere to rise. This heat is then radiated back into space in the form of infrared radiation.

Hence, the heat or energy that Earth receives from the sun is primarily absorbed by the Earth's surface and atmosphere. Some of the absorbed energy is re-radiated back to space as infrared radiation, while some of it is trapped by greenhouse gases in the atmosphere.
