Oxygen-poor blood flows out of the heart and into the lungs. Nutrients and oxygen are sent to other cells and parts of the body. The blood then returns to the heart to begin the process again. Which of the body's systems is the above process describing? Answers (A) -The skeletal system (B)-The digestive system (C)-The respiratory system (D)-The circulatory system
Answers
Answer:
(D)-The circulatory system
Explanation:
lol just did it
and pls give me thanks
The circulatory system is the system which consist of blood vessels, heart, and blood. The main function of this system is the transport of oxygen and minerals to all the cells of body. Thus, the correct option is D.
What is Circulatory System?The circulatory system of body consists of all the blood vessels, blood and heart. In this system, blood travels through different blood vessels (arteries, veins, and capillaries) in all parts of the body.
The blood is the main fluid of the body that contains hemoglobin protein which is responsible for the transport of oxygen and carbon dioxide in the body. The blood exchanges gases at the surface of alveoli in the lungs and sends the blood to the heart, heart pumps the blood to all the cells of body.
Therefore, the correct option is D.

If energy is released, free energy must be what?
Answers
Answer:
If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.
Explanation:
Hope it helped!
Answer:
If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.

Answer:
Power
Explanation:
The formula work divided by time is the expression for finding the power consumed or expended by a body.
Power is defined as the rate at which work is done.
Power = [tex]\frac{work done}{time taken}[/tex]
The unit is always expressed in watts and symbolized as W
Work done is force applied to move a body through a certain distance.

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in
a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is
responsible for the change in the mRNA base?
A.silent
B.missense
C.nonsense
D.insertion
Answers
Answer:
A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.
Explanation:
In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.
In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.
For the other options:
Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.Answer:
Silent

A lake in Minnesota was thriving with black bass and bluegill. These particular fish build nests on the sandy bottom of the lake. Now, ecologists are finding that over time a layer of humus has slowly been covering the pond. The ecologists are noting that the populations of black bass and bluegill are declining, and the fish that are able to make nests in humus are rising in numbers.
The ecologists can probably conclude that this event is an example of:
commensalism
parasitism
primary succession

The event described, where a layer of humus covers the sandy bottom of the lake and affects the fish populations, is an example of succession.
Succession is the process of ecological change over time in a particular area. It involves a series of predictable and sequential changes in the composition and structure of an ecosystem.
In this case, the gradual accumulation of humus, a layer of decomposed organic matter, is altering the habitat conditions in the lake.
The decline in the populations of black bass and bluegill, which build nests on the sandy bottom, can be attributed to the changing habitat.
The humus layer is likely making it difficult or impossible for these fish to construct their nests. On the other hand, fish that are capable of making nests in humus, possibly adapted to this type of substrate, are increasing in numbers.
Therefore, the observed changes in fish populations and the altered habitat due to the accumulation of humus indicate a shift in the ecological community over time, which is a characteristic of succession.

What is the difference between glucose and ATP?
Glucose is a storable form of energy, while ATP is a usable form of energy.
ATP is a storable form of energy, while glucose is a usable form of energy.
ATP is only a usable form of energy, but glucose can be used and stored.
Glucose is only a storable form of energy, but ATP can be used and stored.
Answers
The main difference between glucose and ATP is that Glucose is a storable form of energy, while ATP is a usable form of energy.
Glucose is storable form of energy because it can't be used as energy until it can be broken down by mitochondria of the cell while on the other hand, ATP is the usable form of energy which we can get from the break down of glucose molecules. Our cells use ATP as a fuel to do various activities of the cell so we can conclude that in glucose, energy is present in stored form whereas ATP is used as energy in various activities.
