Certain materials are needed by the mitochondria to make energy. Which of the following is most responsible for getting the
materials into the cell?
O A The materials need to Love through the cytoplasm to get to the mitochondria
B The cell membrane lets the materials into the cell so they can get to the mitochondria
OCThe cell wall lets the materials into the cell so they can get to the mitochondria
D. The materials need to move through the lysosome to get to the mitochondria
Answer:
C. The cell membrane lets the materials into the cell so they can get to the mitochondria
Explanation:
The cell membrane regulates the entrance and exit of certain molecules inside the cell. Some molecules can easily pass through the phospholipid bilayer via passive transport. Others use protein channels, and some require movement by active transport, or endocytosis.

Answer:
the molocules diffusing are smaller in A than in B
Explanation:
Answer:
lol its simple...
Explanation:
we know that cells have a cell membrane, also called selectively permeable membrane that allows only selective things to get in or out of the cell, so A is able to diffuse. May be B is something important to the cell...XD

Volcanoes are usually formed as a result of _____.
a transform fault boundary, where both plates are oceanic
a convergent boundary, where both plates are continental
a convergent boundary, where at least one of the plates is oceanic
a divergent boundary, where at least one of the plates is oceanic
Answer:
a transform fault boundary, where both plates are oceanic
Explanation:
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope.
Answer:
a transform fault boundary, where both plates are oceanic

In science, a theory is different from how we use the term "theory" to apply to everyday ideas. The statement "It’s only a theory" might mean something very different than "theory" when used as a scientific term. What is the best way to explain the word, "theory" when used in science?
A. In science, there is no difference between a law and a theory.
B. In science, there are few principles that can be considered theories.
C. In science, a theory is well supported by observations and/or experimental data.
D. In science, a theory is a completely accurate and reliable fact about natural events.
Answer:
C
Explanation:
The correct answer would be that in science, a theory is well supported by observations and/or experimental data.
Theories are usually derived from testing hypotheses. Untested statements from observations are referred to as theories. When hypotheses are tested using a series of independent experiments and found to be true, they become theories.
Hence, theories are well supported by observations and data in science. A theory remains accurate for as long as there are no contradictory findings to it. Theories can, however, be modified once there are data to back them up.
The correct option is C.
What would be the main problem with reproduction if meiosis did not take place to form sex cells?
Answer:
Fertilization would result in a zygote with twice as many chromosomes as the parents.
Explanation:
Meiosis creates four haploid cells from a diploid parent cell. These haploid cells are the sex cells - sperm cells and egg cells.
Since these cells are haploid (containing 23 chromosomes, half the amount of chromosomes as the parent diploid cells), when they fuse during fertilization, they form a diploid zygote containing 46 chromosomes.
Answer:
B) Fertilization would result in a zygote with half as many chromosomes as the parents.

Which best explains how to oxygen Atoms,
each with six valence electrons can bond with each other?
Explanation:
Two oxygen atoms bonds with each other via covalent bonding.
In the formation of covalent bonds, two atoms with little to no electronegativity difference combines by sharing of the valence electrons. This why homonuclear molecules can be formed.
Two atoms of the same kind having zero electronegativity difference forms this covalent bonds. There is equal sharing of electron pair between the atoms and there is no electrostatic charge on the molecule.For the oxygen atom with 6 valence electrons;
two electrons are shared by each atoms to make a complete octet and a stable molecule.
Exchange of oxygen and carbon dioxide in the lungs uses which mode of cellular transport?
a
endocytosis
b
facilitated diffusion
c
filtration
d
simple diffusion
Answer:
D: Simple Diffusion
Explanation:
Diffusion is a transport driven by a concentration gradient. Gas molecules move from a place of high concentration to an area of low concentration. Knowing when blood is low in concentration and high in carbon dioxide it goes under gas exchange with air into the lungs.
