Answer:
Conversely, exhalation moves the diaphragm up into the chest cavity and reduces the space in it. This forces the air, which is dense with carbon dioxide at that point, out of the lungs and windpipe. It then exits the body either through the nose or mouth. Usually, this requires no physical effort from the body.

Answer:
By crossing plants with purple flowers, dominant, with plants with white flowers the offspring will be 100% purple because all the offspring will receive at least one dominant allele.
Explanation:
The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.
Parental generation:
Plant with purple flowers PP Plant with white flowers ppCross: PP X pp
Punnett Square :
Alleles P P
p Pp Pp
p Pp Pp
Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.
According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.
Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is true breeding for yellow seeds?
The green trait is the dominant trait.
The offspring will inherit one allele from each parent.
The offspring will have both green and yellow seeds.
Each offspring will have a unique set of alleles.
Answer:
The offspring will inherit one allele from each parent
Explanation:
Just did EDGE
The statement 'the offspring will inherit one allele from each parent' describes the offspring of the F1 generation when crossing a pure green seeds pea plant with a pure yellow seed pea plant.
What is an allele?An allele is a given gene form, diploid organisms inherit two alleles for gene locus, one from each parent.
A diploid individual can be for a given gene locus:
Homo-zygousHeterozygousAn individual is homo-zygous when it inherits the same allele or gene variant for a particular gene locus.
Conversely, an individual is heterozygous when it inherits different alleles for a given gene locus.
In conclusion, the statement 'the offspring will inherit one allele from each parent' describes the offspring of the F1 generation when crossing a pure green seeds pea plant with a pure yellow seed pea plant.

Why is the earth considered a magnet? What is a permanent magnet? describes an electromagnet
Answer: *See Explanation*
Explanation: The earth's core "generates" its own magnetic field....so it is considered a magnet. A good example of a "Permanent Magnet" would be the Earth's crust. Not the crust itself, but the effect it causes. A "Electromagnet" is made by passing electric currents through a coil surrounding it. (I know, it's a bit confusing.) Check other sources if it is too confusing.

2. What does it mean if a micrograph is "false-colored?"
It means that the object has color created by the computer since electron microscopes really see in black and white. ... They usually range in sizes between 5-50 micrometers, they are surrounded by a cell membrane, and usually can't be seen without a microscope.
A micrograph is said to be false-colored when there is color created by the
computer involved in the printing of the picture.
A micrograph is a pictorial representation of objects seen under a
microscope. The view of objects under microscope is usually in black and
white color. The micrograph is therefore meant to also be in black and white.
This is the reason why when there is a color in the micrograph, it is referred
to as being false-colored.

Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

This question is incomplete as it lacks a word bank, the word bank are:
Ions
Electrons
Isotopes
Molecules
Covalent
Negative
Ionic
Molecular
Hydrogen
Point
Element
Ionic compound
The answer is:
1. Ions
2. Ionic
3. Covalent
4. Molecule
Explanation:
An ION is a charged atom i.e. an atom with positive (+) or negative (-) charge, which results when an atom loses or gains electrons respectively. The ions of different elements are held together by bonds called IONIC BONDS, which are bonds that form as a result of the difference in electric charges or electrostatic forces between the atoms involved. For example, an ionic bond forms between NaCl because there is an electrostatic force between the positive Na+ ions and negative Cl- ions.
However, on the contrary, when electrons are shared between atoms, a COVALENT BOND is formed. The atoms share their valence electrons to form a MOLECULE, which comprises of two atoms.
