Answer:

True.

Explanation:

A hypothesis is a possible explanation to an unexplained situation that is based on limited or not enough evidence. Therefore, this explanation has not been proven.

If, through scientific experiments and research, enough evidence is gathered to prove this explanation to be true, then it becomes a theory. A scientific theory generally integrates various hypothesis to support it. This allows a theory to change through time as more hypothesis are developed, creating a more accurate and reliable theory.

Final answer:

Courtney should randomize her diet by eating only protein meals on some days and only carbohydrate meals on others based on a coin toss to truly understand the impact of meal type on her race performance.

Explanation:

To properly assess the impact of the type of meals on her race time, Courtney should implement a controlled experiment that isolates the variable of the meal composition. The best option here is:

By comparing her race times on days following a high-protein meal to days following a high-carbohydrate meal, she can see which diet might be more beneficial for her performance. It's essential to remember that many distance runners carb load before a race because carbohydrates are stored as glycogen in the muscles and liver, providing a ready source of energy for endurance activities. Eating complex carbohydrates is a common practice so that the body has stored energy to tap into during the run.

the element zinc has 30 protons

Explanation:

Atomic number is the sum of all the number of protons present in an element. And, mass number is the sum of total number of both protons and neutrons present in an element.

When an atom is neutral in nature then its number of protons is equal to its number of electrons.

Since, it is given that atomic number of zinc is 30 so, it means that number of protons will also be 30.

Thus, we can conclude that there are 30 protons in an uncharged zinc atom.

The light reaction begins in photosystem 2 (PS2).

In the process of light reactions in photosynthesis energy is generated so that it can be use in the dark reactions.

During light reaction, water molecule breaks down into oxygen molecule and an electron.  this free electron attains  attains a higher energy level in the reaction center of photosystem 2. The state of an unstable electron undergoes an electron transport chain (ETC). The electron flows from PS2 to cytochrome and then to photosystem 1 (PS1). In PS1 the light-independent energy takes place where further electrons are transfered to NADPH.

Bone physiology is intimately connected to its anatomy, as the structure of bones dictates their function in body support, protection, and movement. The continuous remodeling of bone as well as specific anatomical features, like the arrangement of hand bones, exemplify the form-function relationship.

The physiology of a bone is deeply related to its anatomy because the physical structure of bone (its anatomy) determines how it functions (its physiology). Bones are not inert structures; they are dynamic and continuously remodeled throughout one's life to adapt to various stresses. Bone remodeling is a physiological process where approximately 10% of bone mass is turned over annually. This ongoing process helps the bone maintain its strength and adapt to the mechanical load it is subjected to.

Bone's structure is a composite of organic collagen and inorganic hydroxyapatite that provides the necessary strength to support body weight. The outer portion, called cortical bone, is dense, while the inner part, known as cancellous bone, is spongy. This specialized structure enables bones to perform their physiological functions, supporting body structures, protecting organs, and facilitating movement in conjunction with muscles.

Similarly, the anatomy of the human hand, with its unique arrangement of bones, reveals a close relationship with its function; the thumb's opposition to the four fingers allows for complex manipulations like pinching, grasping, and typing. Understanding the anatomy and physiology together enhances comprehension of how form and function are correlated in living organisms.

Fungi, it's the only one that's not microscopic

Fungi, it's the only one that's not microscopic.

An organism that can make its own nourishment by the use of light, water, carbon dioxide, or other substances is an autotroph. Autotrophs are also referred to as producers because they make their own nourishment.

Although plants are the most well-known autotroph, there are numerous more types of autotrophic creatures. Algae, which are aquatic plants that are recognized by their larger forms as seaweed, are autotrophic.

The majority of autotrophs produce their food through a process known as photosynthesis. In photosynthesis, autotrophs use the sun's energy to turn carbon dioxide from the air and water from the soil into glucose, a nutrition.

Therefore, Fungi, it's the only one that's not microscopic.

Sunlight angle shapes climate zones: shallow angles cause cold polar climates, varying angles lead to temperate fluctuations, direct angles create tropical heat, and changing angles result in arid extremes.

The angle of sunlight significantly influences the climate of each climate zone. In polar zones, where the angle is shallow, sunlight is spread over a larger area, resulting in lower temperatures. In temperate zones, varying angles across seasons cause temperature fluctuations. Near the equator, where sunlight strikes directly, tropical climates experience high temperatures.

Subtropical zones have consistent, intense sunlight, yielding warm climates. The angle's changing inclination in arid zones leads to extreme temperature shifts. Lastly, in high-altitude regions, steep angles result in cooler temperatures. Overall, sunlight angle affects the distribution of heat, playing a pivotal role in determining the temperature and characteristics of each climate zone.

Final answer:

The angle at which sunlight strikes Earth, influenced by its 23.5-degree axial tilt, results in the differing climate zones across the globe. Direct sunlight near the equator leads to a warmer climate, while increased reflection near the poles causes cooler conditions.

Explanation:

The angle of sunlight plays a critical role in shaping the climate of various zones on Earth. The Earth's 23.5-degree axial tilt leads to variations in sunlight exposure throughout the year. During the summer season in either hemisphere, the tilt is such that the Sun's rays hit the Earth at a more direct angle, leading to increased solar energy absorption and warmer temperatures.

Conversely, during the winter, the tilt causes the Sun's rays to strike the Earth at a sharper angle, resulting in less energy absorption and colder conditions. The regions closest to the equator receive the most direct sunlight, which leads to a warmer climate year-round. In contrast, the poles are characterized by an increased angle of incoming solar radiation, leading to more reflected sunlight and a cooler climate. The culmination of these factors influences the distribution of the Earth's climate zones.

Answer:

Your answer is B) Brain

Answer:

B) brain

Explanation:

Feedback mechanisms are actions capable of controlling the body's homeostasis (balance).

The brain has the main role in these processes, promoting antagonistic actions, dividing into positive and negative feedbacks, such as the increase or decrease in body temperature or blood glucose level, for example.

Positive feedbacks act to amplify actions that promote changes in the body, while negative feedback acts to reverse changes that have occurred. These are more common than the positive ones.

Negative feedback helps achieve and maintain the set point within a system, acting as a control mechanism. In contrast, positive feedback lacks the controlling aspect and instead accelerates the direction of change. Hence, the correct option is c.

The primary difference between negative and positive feedback mechanisms in the body involves the system's response to changes. Negative feedback mechanisms work to maintain homeostasis by reversing the direction of a change when the levels of a variable become too high or too low. For example, the regulation of blood glucose levels through the release of insulin and glucagon is an instance of negative feedback: insulin lowers high blood glucose levels, while glucagon raises low blood glucose levels.

On the other hand, positive feedback mechanisms amplify the changes the system is undergoing, pushing it further away from its original state. These are less common because they could disrupt homeostasis, but they are normal and critical when there is a specific endpoint, such as during childbirth where the release of oxytocin intensifies contractions until delivery.

Cell structures that provide energy to the cell are called mitochondria found in eukaryotic cells found in animals, plants, fungi, and many  single-celled organisms

Mitochondria are specialized structures found in eukaryotic cells. They are often referred to as the "powerhouse" of the cell because they are responsible for producing most of the cell's energy in the form of ATP (adenosine triphosphate).

The process of energy production in mitochondria is called cellular respiration. It involves a series of chemical reactions that take place in the inner membrane and matrix of the mitochondria. During cellular respiration, glucose and other molecules are broken down to release energy. This energy is then used to produce ATP, which can be used by the cell for various function

The magnification of the bacterial cell image is 18 mm / 0.002 mm = 9000

Magnification means how much bigger the image is compared to the object itself. In this situation, the picture of the tiny bacteria cell is zoomed in to be 9000 times bigger than it really is.

This means that if you were to use a microscope that makes things look 9000 times bigger, a bacterial cell would look like it is 18 mm long.

It is important to understand that making an image bigger does not make it clearer. Resolution means the skill to see the difference between two points that are very close together. To make an image clearer, use a microscope with a bigger number called numerical aperture (NA).

Answer:

A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.

Explanation:

A molecule is the smallest part of a substance that can have the properties of that substance.

A structure by the chemical bonding of two or more two atoms is called a molecule. The molecule is the smallest part of a substance that has the same properties as a substance.

For example, a molecule of water had the same properties as that of water. If it is broken down into its constituent atoms, hydrogen and oxygen, these atoms will have completely different properties than that of water.

Molecules are structures that form the basics of the study of chemistry. Molecules are written with the symbol of their constituent atom with a number as a subscript representing the number of those atoms in the molecule.

For example, a molecule of water is represented by the formula H₂O, where H₂ represents that there are two atoms of hydrogen per atom of oxygen.

Therefore, the molecule is the smallest part of a substance that can have the properties of a substance.

Water's cohesive property, which makes it stick together in drops, is due to its molecular structure that facilitates hydrogen bonding. The polarity of water molecules leads to the formation of hydrogen bonds, which makes water a structured liquid with high surface tension.

The Property of Cohesion in Water

The property of water indicated by the data is its cohesive nature. Water molecules exhibit a strong tendency to stick together, forming drops rather than existing as separate molecules. This behavior is most visible when observing water dripping from a leaky faucet or accumulating in dew drops.

The cohesive property of water is explained by the molecular structure of water, or H₂O. Each water molecule consists of one oxygen atom covalently bonded to two hydrogen atoms, creating a polar molecule with a partial negative charge on the oxygen and partial positive charges on the hydrogens. This polarity allows water molecules to form hydrogen bonds with each other, where the oxygen of one water molecule attracts the hydrogen of another. These bonds create a network that holds the molecules together, contributing to water's high surface tension and its ability to form drops.

Hydrogen Bonding in Water

Hydrogen bonding is the molecular structural feature responsible for many of water's unusual properties. The bond is relatively weak on its own, but when many hydrogen bonds form between water molecules, they collectively create a stable, structured liquid. This extensive hydrogen bonding is what gives water a high boiling point, high heat capacity, and the ability to dissolve numerous substances, which is why water is often called the 'universal solvent'.

In essence, the structure of water molecules and the network of hydrogen bonds between them are the keys to understanding why water behaves in such distinctive ways compared to other molecules of similar size.

Answer:

The activities of enzyme depends on the temperature, ionic conditions and the pH of the surroundings.

Explanation:

Effect of temperature on enzymes

Enzymes show low level of functioning at lower temperatures. As the temperature is raised, the activity of the enzyme increases. The enzyme activity becomes optimal at a specific temperature. Beyond this temperature, the enzyme's activity rate starts to decline until it gets denatured.

Effect of ionic conditions on enzymes

Studies show that certain enzymes require some cations for functioning. But an increased amount of cations or anions can inhibit the functioning of the enzymes.

Effect of pH on enzymes

Each enzyme has an optimum pH at which it works best. If the pH is increased or lowered than this optimum pH, then the activity of the enzyme starts declining until it gets denatured. Most enzymes work best at pH 7.0
