A researcher conducts an experiment on the secretion of a particular hormone in mice. Scientists inject mice with a substance that
stimulates the production of the hormone. The scientists then test the levels of hormones produced by the mice. The tool used to
measure the hormones consistently detects the levels at 10 points lower than the a (
Answers
Answer:
The correct answer is - accurate.
Explanation:
Systematic measurement errors take place when there is a consistent inaccuracy found in the result of the measurement. In the given case here is consistent 10 points lower than the actual value of hormones produced in the mice. the tool that is measuring the level of the hormones in the mice is showing systematic error and measurements are not accurate.
Thus, the correct answer is - accurate.

What are sex chromosomes? What is the sex chromosome combination for human males and females?
Answers
Answer:
(Wow! Weird how this pooped up, I just finished this biology lesson.)
Sex chromosomes are the gene that decides on our gender. The males have X and Y sex chromosomes (XY). Females have only two X sex chromosomes (XX).
More info: Because males have both X and Y sex chromosomes, their genes decide the offspring's gender.
Answer:
The sex chromosomes are referred to as X and Y, and their combination determines a person's sex. Typically, human females have two X chromosomes while males possess an XY pairing. This XY sex-determination system is found in most mammals as well as some reptiles and plants

How many water (H2O) molecules could you line up end to end in a nanometer?
Answers
Answer:Molecules have size and different molecules are different sizes. When talking about the size of a molecule, most scientists will mention its molecular weight. That is the total weight of all of the atoms in the molecule. So water, which is made up of two hydrogen atoms (1 atomic mass unit each) and one oxygen atom (16 atomic mass units) has a molecular weight of 18 (well, 18.01528 to be exact). Glucose has a molecular weight of 180. DNA, which is very long, can have a molecular weight that is around 1010 (about the weight of one human chromosome).

Why does the amount of protons and electrons stay the same in stable atoms?

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

Which best explains how green plants absorb energy from the sun?
A) Sunlight heats up the outside of a leaf
B) Chemical Bonds in a glucose are formed
C) A photon strikes electrons in special molecules in a cell
D) Carbon dioxide combines with water to form glucose molecules.
Answers
Answer:
the answer is C
Green plants absorb energy from the sun when "A photon strikes electrons in special molecules in a cell"
Green plants are unique organisms being that they possess the ability to capture and utilize energy from the sun. This is possible because they possess special pigments in their CHLOROPLAST called CHLOROPHYLL. The general process whereby green plants capture and utilize sun's energy is called PHOTOSYNTHESIS.
During photosynthesis, a photon of light strikes electrons in the thylakoid lumen of the chloroplast. This facilitates the synthesis of ATP (energy) in further reactions that takes place in the chloroplast.
Therefore, green plants are able to obtain energy from the sun when photons (beam of light) strikes electrons in their CHLOROPLAST.

which of the following determines the identity of an element?
a. atomic number
b. mass number
c. atomic mass
d. overall change
Answers
The identity of any element is given out by the atomic number it carries thus every element has different atomic number. The correct answer is option A.
What does atomic number signify ?It signifies the number of electrons and the number of protons which are present in any element as the atomic number is equal to the number of electrons and the number of protons as well.
Atomic number is a unique property that is given out to element where the basis of their characters and the properties signifies their basic characters on which the elements will align themselves for example the elements having the atomic number as the 1 at the end usually has 1 electron in their last atomic shell same for 2.
On the basis of their properties elements are divided into various groups where the 1st one is called as alkali metal and the 2nd one is called as alkaline earth metals, 17 is called as halogens and the last 18th is called as noble gases.

Put the steps of DNA Replication in the correct order
Answers
Answer: Initiation Elongation and termination
Explanation:
There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.
The correct order for DNA replication is B, A, C and D.
During DNA replication, first the DNA double helix break down the middle part between base pairs. The enzyme DNA polymerase moves along the exposed strands and adds complementary nucleotides to each nucleotide in each existing strand.
After that a complementary strand is produced for each of the two strands of the original double helix. Thus two new identical DNA molecules have been produced and the replication process is finally completed.
