Answer:
The correct answer will be- Scientific law
Explanation:
A statement proposed before the experiment related to the natural phenomenon which explains the event to a limited extent is known as the scientific hypothesis.
The scientific hypothesis when tested and proved by the researcher and fellow researchers many times transforms the hypothesis either to a scientific law or theory.
The scientific law is a statement which can contain quantifiable variables which describes the pattern and behavior of the natural phenomenon but do not explain why this behavior is observed which in turn is explained by the scientific theory.
Thus, Scientific law is the correct answer.

List the types of substances that most readily diffuse through a cell membrane
Small, nonpolar or hydrophobic molecules such as oxygen and carbon dioxide readily diffuse through a cell membrane by simple diffusion. Polar water molecules also diffuse but often utilize aquaporins, while ions and larger hydrophilic substances require special transport mechanisms.
The types of substances that most readily diffuse through a cell membrane include small, nonpolar, or hydrophobic molecules. These can pass through the lipid bilayer by simple diffusion, which is a form of passive transport that does not require energy. Notably, gases such as oxygen (O2) and carbon dioxide (CO2) diffuse freely across the cell membrane along their concentration gradients.
Other hydrophobic substances, like lipids, can also pass through the membrane with ease. Even though water is polar, it can still diffuse across the plasma membrane, but uses special channels known as aquaporins to facilitate its movement more efficiently. In contrast, ions and larger hydrophilic molecules require special transport proteins to pass through the membrane.

Which of these sources add water to lakes? Select the three correct answers. A.Rain runoff B.Groundwater C.Melting snow D.Ocean waves
Answer: A. Rain runoff B. Groundwater C. Melting snow
A lake is a water body that is surrounded by land. They are found in mountains, deserts, plains and in seashores. The water in lakes comes from rain, snow, melting ice, streams, groundwater and seepage. Mostly lakes contain freshwater.
The correct answers are Rain runoff, groundwater, melting snow.
Water from the rain flows through various paths and goes into lakes. It carries various types of small leaves or soil particles along with it into the lake.
The ground water can also form lakes and is the source of freshwater.
The melting snow is also the source of fresh water that flows and reaches the nearby ponds or lakes present in the nearby areas.

Amino acids are the monomers of this biomolecule.
lipids
nucleic acids
carbohydrates
proteins
Final answer:
Amino acids are the monomers of proteins, each consisting of a central carbon atom, an amino group, a carboxyl group, a hydrogen atom, and a variable R group. option D
Explanation:
Amino acids are the building blocks, or the monomers, that make up proteins. Every amino acid shares the same core structure, consisting of a central carbon atom (alpha carbon), an amino group (-NH₂), a carboxyl group (-COOH), and a single hydrogen atom. Diversifying these amino acids is their R group, which is different for each amino acid, giving it unique characteristics. The union of amino acids through condensation reactions forms polyamide polymers known as proteins, playing an essential role in various biological functions.
Hakeem wants to explain why only one side of the moon is visible from Earth. Which comparison would provide the best support?
the orbital period of Earth with the rotational period of the moon
the orbital period of the moon with the rotational period of the moon
the orbital period of the moon with the rotational period of the Earth
the orbital period of Earth with the orbital period of the moon
The Moon orbits Earth once every 27.3 days and spins on its axis once every 27.3 days. This means that although the Moon is rotating, it always keeps one face toward us.
What is rotation?Rotation refers to an object's spinning motion about its own axis and revolution refers the object's orbital motion around another object.
It is also known as synchronous rotation this is why we only ever see the Moon's nearside from Earth.

What are the primary effects of calcitriol on the body? check all that apply?
Calcitriol has several primary effects on the body, including promoting calcium absorption, maintaining serum calcium and phosphate levels, and supporting bone health and other vital functions.
Explanation:The primary effects of calcitriol on the body include stimulating the intestines to absorb calcium from digesting food, promoting the absorption of calcium and phosphate from the digestive tract, and indirectly increasing calcium uptake by the small intestine.
Calcitriol is vital for maintaining normal serum concentrations of calcium and phosphate, which are important for bone health, muscle contraction, hormone secretion, and neurotransmitter release.
Inadequate levels of calcium can lead to disorders like osteoporosis and osteomalacia in adults and rickets in children.
Calcitriol a) increases blood concentrations of calcium and c) Increase blood concentration of phosphorus by enhancing their absorption and reabsorption in the body. The effects are crucial for maintaining bone health and overall mineral balance.
Calcitriol, the active form of vitamin D, plays a crucial role in regulating calcium and phosphorus levels in the blood. The primary effects of calcitriol on the body include:
Increase blood concentration of calcium: Calcitriol promotes the absorption of dietary calcium from the gastrointestinal tract and enhances the reabsorption of calcium in the renal tubules, reducing calcium loss in the urine.Increase blood concentration of phosphorus: Calcitriol works together with parathyroid hormone (PTH) to increase phosphorus absorption in the gastrointestinal tract, contributing to higher blood phosphorus levels.Based on these effects, the correct answers are (a) and (c).

They are at least ten times larger.
They can reproduce asexually.
They are eukaryotes.
They consist of both single- and multi-celled organisms.
They have flagella to move.
Ans.
Protists are unicellular or multicellular eukaryotic organisms, such as amoeba, paramecium, and euglena. Protists may be heterotrophic or autotrophic as some protists can synthesize their own food by using sunlight.
Generally, eukaryotic cells are ten times larger than prokaryotic cells. It means protists are also 10 times larger than bacterial cells.
Thus, correct options are:
-They are at least 10 times larger.
-They are eukaryotes.
-They consist of both single- and multi-celled organisms.
Protists are different form bacteria as bacteria are single-celled, prokaryotic organisms. Thus, the correct options are 'they are eukaryotes' and 'they consist of both single- and multi-celled organisms.

The movement of air into and out of the lungs, or breathing, is properly referred to as pulmonary __________.
The movement of air into and out of the lungs, or breathing, is properly referred to as pulmonary ventilation.
Pulmonary ventilation includes two main processes:
Inspiration (Inhalation): This is the process of drawing air into the lungs. During inspiration, the diaphragm and external intercostal muscles contract. This contraction increases the size of the thoracic cavity and lung volume, causing the ribs to expand and move outward. The pressure within the lungs (intra-alveolar pressure) becomes lower than the atmospheric pressure, causing air to flow into the lungs.Expiration (Exhalation): This is the process of expelling air from the lungs. During expiration, the diaphragm and intercostal muscles relax, causing the thorax and lungs to recoil. This decreases the volume of the thoracic cavity, increasing the pressure within the lungs (intra-alveolar pressure) to be higher than the atmospheric pressure, forcing air out of the lungs. During forced exhalation, the internal intercostal and abdominal muscles may also be involved to push air out more effectively.Why are the terms dominant and recessive misleading?

Water is unusual because it expands as it freezes. Very few substances have this property. The reason liquid water is more dense then ice can be best explained by?
Answer:
When the water freezes a reticulum is formed that occupies more space and is less dense than liquid water since the water on cooling decreases its volume. The reason why the water is denser in a liquid state is because, when it goes to a solid state, the water molecules are cold and still and the hydrogen bonds keep them constantly at the same fixed distance, while when they are in a liquid state, their hydrogen bonds are not at a fixed distance, but more separated.
