D. they migrate to a new location where prey and shelter are more abundant and easier to find.
Answers
Answer:
Answer A:
a new disease develops , so having more genetic variation among there off spring is an advantage.
Not 100% sure but A seems the most likely answer.
Explanation:
The question is asking where sexual reproduction is more of an advantage and I'd say that having more genetic variation would be caused by sexual reproduction and not as much or at all in asexual reproduction.
with B, C, and D. It wouldn't really be an advantage to do one or the other in this context.

7. Calculate the net charge of the following atoms.
Atom A: has 6 protons and 4 electrons
Atom B: has 9 protons and 9 electrons
Atom C: has 10 protons and 14 electrons
Atom D: has 33 protons and 29 electrons
Answers
Answer:
any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have.
Explanation:
Answer:
Atom A: +2 Atom B: 0 Atom C: -4 Atom D: +4
Explanation:
We know that protons have a positive charge and electrons have a negative charge. Therefore, we will treat the electrons as a negative number. The net charge is the sum of electrons and protons.
Atom A = 6 + (-4)
because electrons as negative.
Net charge = +2
Atom B = 9 + (-9)
Net charge = 0, or neutral
Atom C = 10 + (-14)
Net charge = -4
Atom D = 33 + (-29)
Net charge = +4

Which choice is an element? carbon dioxide water carbon air
Answers
Answer:
carbon
Explanation:
Considering the definition of elements ans compounds, carbon is an element.
Elements are simple substances that cannot be broken down by common chemical methods. The atoms in an element are the same as each other, yet they are different from those in other elements. In addition, the elements are represented by a symbol and can be found in the periodic table.
On the other hand, compounds are substances that are the result of the chemical union of two or more elements. This combination makes it impossible to identify each element by its individual and original properties. Compounds can be separated by chemical action.
In summary, the element is a pure chemical substance formed from an atom, which is characterized in that it cannot be divided or transformed by a chemical reaction. Whereas a compound is a pure chemical substance made up of a particular set of molecules or ions that are chemically bound together.
So, being:
carbon dioxide: composed of carbon and oxygen water: composed of two atoms of hydrogen and one of oxygenair: composed mainly of oxygen and nitrogenthen, carbon is an element.

https://brainly.com/question/20716171?referrer=searchResultshttps://brainly.com/question/13654839?referrer=searchResultsWhich of the following represents the velocity of a light wave?
O A. E = fx2
O B. c = hxf
O C. E = hxf
O D. c = fx2
Answers
Answer:
D. c = fλExplanation:
c = fλ
where" c "is the speed of light ,
• "f" is the frequency of the electromagnetic waves,
• " λ" is its wavelength.
The term that represents the velocity of a light wave is c = fx2. The correct option is D.
What is velocity?Velocity is the speed by which an object moves or do any motion. When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time.
Light waves are the movement of waves in a direction. There are two types of transverse and electromagnetic. They are divided on the way of their movement.
The velocity of the light wave is the speed at which the light wave moves in a specific direction in time. The formula is given below:
c = fλ
Where c is the speed of light.
f is the frequency of the electromagnetic waves,
λ is its wavelength.
Thus, the correct option is D. c = fx2.
