- Leeuwenhoek: he built biconvex lenses and with them he observed microorganisms such as bacteria and protozoa and cells such as sperm and red blood cells.

- Schleiden: he studied embryonic cells and discovered the nucleolus

Answer:

Evolution works independently of natural selection

Organisms best suited for environment survive and reproduce statement accurately describes natural selection

Explanation:

Natural Selection: Organism adapts itself to the particular environment to survive and reproduce.

The theory of Natural selection was popularized by Charles Darwin. He explained that organisms evolved, they can survive when they get adapted better to the environment.

Natural selection is also called the'' survival of the fittest''. The organism which gets adapted to the environment will survive.

The more desirable characteristic will pass from parents to offspring.

Final answer:

The best example of a hypothesis from the given options is 'If temperature is increased, then ice will melt more quickly.' This statement is testable and formatted correctly (If... then...), which aligns with the definition of a hypothesis in scientific inquiry.

Explanation:

To identify the best example of a hypothesis, it is important to understand what constitutes a hypothesis. A hypothesis is a suggested explanation that can be tested and is typically formatted as 'If... then...'. Therefore, the best example of a hypothesis from the options provided is, 'If temperature is increased, then ice will melt more quickly.' This statement sets up a condition (increased temperature) and predicts an outcome (ice melting more quickly) that can be tested through experimentation.

An example to illustrate the concept could be how you can dissolve sugar more rapidly in hot water, which demonstrates the principle that certain processes increase with temperature. To further explain, if a student approaches a warm classroom and asks why it is warm, proposing a hypothesis such as 'The classroom is warm because no one turned on the air conditioning' follows the correct structure. It is testable because the student can turn on the air conditioning to see if the classroom's temperature decreases.

Final answer:

Early man desalinated sea water primarily by boiling it off to extract salt, a process with historical evidence such as the Han-era deep drilling for salt brine. Other desalination methods throughout history have included freezing and reverse osmosis.

Explanation:

Early man removed salt from sea water by boiling off the water. This desalination process was essential for producing salt for food preservation and nutrition. Historical evidence, such as the Han-era practices, shows that ancient civilizations used techniques like deep drilling for salt brine and then boiling the water with natural gas to extract salt. This process can be likened to distillation, where the principle involves evaporating the water and then condensing it to leave behind impurities.

Moreover, desalination methods have evolved where various scientific principles have been applied. For instance, sea water can also be purified by freezing, a process where ice forms and leaves the salt and other impurities in the liquid water, or through reverse osmosis, which uses a semi-permeable membrane to separate salt from water.

Chlorophyll, the green pigment located in the thylakoid membranes of chloroplasts, is essential for photosynthesis as it absorbs sunlight and converts it into chemical energy used to produce plant sugars.

Chlorophyll is a vital green pigment found within the thylakoid membranes of chloroplasts, the organelle where photosynthesis occurs. It plays an essential role in the process of photosynthesis by absorbing sunlight and converting it into chemical energy. This energy is then used, along with water and carbon dioxide, to produce sugars for the plant, which are essential for its growth and development.

In chloroplasts, chlorophyll molecules are meticulously embedded in the thylakoid membranes, and when they capture light energy from the sun, they energize electrons within the chlorophyll molecule. These high-energy electrons are then used in a series of complex reactions to generate energy-rich compounds like ATP and NADPH, which subsequently fuel the Calvin cycle to synthesize sugars.

The presence of chlorophyll in plants also contributes to their green color, as it reflects green wavelengths of light while absorbing other wavelengths, particularly those in the blue and red spectrums, which are crucial for photosynthesis.

Explanation:

Weight is defined as the force that the gravity exerts on an object due to its mass. So higher the gravity higher the weight and lower the gravity lower the  weight. The object on planet 'a' that has a force of gravity that is weaker than that of the planet 'b' will have less weight than the object on planet 'b'.

There are several septum's within the body. The term septum simply just means, a divide between two things. If you are referring to the cardiac septum; which separate the heart into left and right sides. There is a top portion of the septum which is called the atrial septum and the bottom portion of the septum; which is called the ventricular septum. They typically keep the deoxygenated blood and the oxygenated blood separated from each other.

If you're referring to the nasal septum, the nasal septum acts as a pathway stabilizer to make sure that the air we breathe in is not "lost" and gets resistance going into our lungs.

The septum in the heart, including the interatrial and interventricular septa, separates the chambers to ensure efficient circulation. The nasal septum, comprising bone and cartilage, divides the nasal cavity into two parts and supports nasal structure and function.

The septum is a central structure in the anatomy of the heart that serves as a divider between its chambers, ensuring proper circulation of blood throughout the body. Two primary types of septa exist within the heart: the interatrial septum and the interventricular septum. The interatrial septum separates the left and right atria and features the fossa ovalis, which is the remnant of the foramen ovale from fetal development. This foramen ovale provided a pathway for blood to bypass the lungs and flow directly from the right atrium to the left atrium before birth. Shortly after birth, it is sealed by the septum primum. The interventricular septum, which is thicker than the interatrial septum, separates the left and right ventricles and is fundamental in maintaining the division between the high-pressure systemic and lower-pressure pulmonary circulatory circuits.

Aside from the heart, the nasal septum is another significant septal structure in human anatomy. It is a flat, midline structure that divides the nasal cavity into two halves, comprising the perpendicular plate of the ethmoid bone, vomer bone, and septal cartilage. This partition plays a critical role in directing airflow and supporting the structure of the nose.
