Why are there two numbers normally given when determining blood pressure?
Answer:
Both numbers are equally important and you need both. There are two because you need both.
Explanation:
When you go to take your blood pressure the top number is the systolic pressure and it measures the amount of pressure in your arteries during the contraction of your heart muscle. The bottom number is called the dialostic pressure and measures the amount of blood pressure of you heart muscle between beats. Healthy blood pressures numbers are 120 over 80, or 120/80.
What changes occur in taste receptors when the membrane is depolarized during receptor potential A. Voltage-gated Ca2 channels open, triggering the release of neurotransmitter. B. Voltage-gated Cl- channels open, triggering the release of neurotransmitter. C. Voltage-gated Ca2 channels open, inhibiting the release of neurotransmitter. D. Voltage-gated Cl- channels open, inhibiting the release of neurotransmitter.
Answer:
A. Voltage-gated Ca² channels open, triggering the release of neurotransmitters.
Explanation:
For taste mechanisms to function properly, it is necessary the activation of taste receptors.
Through the activation of taste receptors, transduction cascades occur, involving ion channels that are located in the apical or lateral membranes. There occurs a subsequent release of chemical neurotransmitters that send signals to the control centers.
Salty and sweet flavors produce the membrane depolarization that results in Ca+ ions´ entrance to the cell. Ca+ initiates the release of neurotransmitters. Afferent gustative neurons receive the message and send it to the control center, the encephalon. After that, gustative cells go back to the initial state, repolarizing.

Look at the chart below to answer this question. Which substance is the LEAST dense of the three substances?
Substance A
Substance B
Substance C
Answer:
Substance B
Explaination: Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.

Why do hydrogen atoms form a molecule but helium atoms do not?
Answer:
Explanation:
In terms of old school electron shells - One Hydrogen atom on it's own has an empty shell, and therefore to fill the shell it needs another electron. In the case of Helium, it already has two electrons at the same energy level - so it cannot accept any new electrons i.e. it cannot form new bonds.
Answer:
Hydrogen atoms can form a molecule as 2 hydrogen atoms together can result in a low energy combination of 2 electrons of the same energy level.
Explanation: Helium atoms already have 2 electrons of the same energy so therefore it cannot accept more.

I believe the answer is copepods
Sand eels represent the trophic level containing approximately 1% of the initial amount of solar energy acquired by phytoplankton.
What is the food chain?The food chain is an ecological diagram used to represent the connections between different trophic levels.
In the food chain, energy flows from producers to primary consumers and so on.It has been shown that approximately 90% of energy is lost in the form of heat for each trophic level.In conclusion, sand eels represent the trophic level containing approximately 1% of the initial amount of solar energy acquired by phytoplankton.

A person pushes the same box with the same amount of force on 3 different surfaces. Which surface exerts the least friction on the box?
*WRITE AS A CER*
Answer:
Read explanation
Explanation:
Surface C exerts the least amount of friction on the box. Evidence that proofs this claim is that the length of time it took the box to stop is greatest compared to surfaces A and B. The box and the amount of force added is the same for each surface test. It would take the box less time to come to a stop the more friction there is upon the surface. Surface A having the quickest stop time meaning it has the most friction and C having the most time showing that it has the least amount of friction. In conclusion, surface C exterts the least amount of friction on the box.

Which of the following is an example of a phenotype (select all that apply)?
Group of answer choices
Brown Hair
GG
RR'
Physical trait
Answer:
brown hair and physical trait
An example of phenotypes are brown hair and physical trait. Therefore, option A and D are correct.
What is phenotype ?A set of an organism's observable qualities or characteristics is known as its phenotype. The phrase refers to an organism's morphology, or its physical form and structure, as well as its physiological and biochemical characteristics, behavior, and the outcomes of that behavior.
We examine the alleles of the parent organisms and predict how frequently the offspring will exhibit those genes to determine a phenotypic ratio. Most of the time, we are aware of the alleles' expression and appearance.
An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same root as the term "phenomenon," simply means "observe." It can therefore relate to anything from a common characteristic, like height or hair color, to a visible type of organism.
Thus, option D is correct.

Describe an adaptation to a plant's life cycle and explain how this adaptation helps the plant survive. Source StylesNormal
Answer:
The adaptation of a plant in an environment ( for example,desert) depends on the structural parts of the plant which enables it to complete it's life cycle.
Explanation:
Plants are found in different types of environment. They need to possess and show some features that will enable them to live successfully and reproduce in that particular environment. Such features may be structural, functional or behavioural which are known as ADAPTATIONS.
Furthermore, in environment where there is scarcity of water supply, plants known as xerophytes can survive or thrive. They show the following adaptations:
--> well developed roots: the roots grow down to great depths if necessary and branch extensively in order to absorb water from as large an area as possible.
--> presence of swollen stems: These stems contains water storage cells which are called succulents. They help the plant withstand long period of drought.
--> Reduced leaves: This helps in reducing water loss from leaves through transpiration. For example in plants like the cacti, the leaves are reduced to spines.
Therefore, these structures helps the plant survive in its present environment.
