Answer:

water clarity

Explanation:

The factor that will best contribute to the measurement of environmental quality is : ( B ) Water clarity

Water clarity shows how far light can penetrate a water body. A very clear water in an environment shows that the water bodies contain little or no suspended soil particles.

Very clear water found in a environment represents a very high quality of live in the environment and can be used to measure the environmental quality.

Hence we can conclude that The factor that will best contribute to the measurement of environmental quality is : ( B ) Water clarity

Answer:

Sensory receptor interact with stimuli, such as light  sound temperature and pain which is transformed into the code that is carried to the brain by the chain of neurons. Once the signal reaches he end of an axon, which is at the end of neuron, a neurotransmitter is released and the process repeats.

Answer:

Your body perceives the stimuli the brain recognizes the mind decides how the body will deal with the stimuli

Explanation:

When an object is already in motion then we require force to stop it because due to inertia , a body tends to remain in the state of motion unless an external force acts on it .This is in accordance with Newton's  first law of  motion or  law of inertia of motion.

Inertia is the tendency of a body to remain the way it is. It opposes any changes to its state of rest or motion.

The more is the mass of the body , the greater will be the inertia.

External force is the force applied by external agents on the body.

Explanation:

The dashed circle indicates the process of infiltration because the water of precipitation goes inside the soil. Infiltration is the process in which water enters the soil through small opening present on the earth surface. When the clouds are formed, precipitation occurs in the form of rainfall and snowfall. Condensation is a process in which water vapors change into liquid when the environment has low temperature or cool so condensation occurs on the windows of Erica.

Answer:

1-Ecological succession is the process of change in the species structure of an ecological community over time.

2-Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

3-A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system.

Answer:

The correct answer is - amino acids.

Explanation:

Proteins are made up of amino acids by linking together by the peptide bonds therefore the building blocks of the proteins are amino acids and due to amino acids linked together by peptide bond they called polypeptide chain;

Amino acids are small organic molecules form by the process translation and have a central carbon atom with an amino -NH group, a hydrogen atom, a carboxyl group -COOH, and a side chain.

Explanation:

The Rh factor is one of the proteins on RBCs used to indicate whether the blood of two different people is compatible when mixed – such as blood of a mother and her baby at birth.

Explanation:

Answer:

D.Predation

Explanation:

Living organism interact with one another in their natural environment. The interaction of two organisms is called SYMBIOSIS. Symbiosis, however, can be of different types depending on how the organisms relate. One type of symbiotic relationship between organisms is called PREDATION.

Predation is a relationship between two organism in which one organism called PREDATOR kills and feeds on the other organism called PREY in order to obtain energy. In this question, a Manta Ray and a zooplankton is shown.

The Manta ray is described as an aquatic organism that feeds on tiny species like fishes while the zooplankton is a tiny organism found in water bodies. The Manta Ray is the predator that kills and feeds on the zooplankton, hence, the relationship is a PREDATION.

Answer:

ice is a solid.When heat is added it turns into a liquid,its a reversible change.As regarding to the water moleculesWhen water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense. For samples of water that have the same mass, warmer water is less dense and colder water is more dense.Im not sure if this helps but try it out :)
