Avanços no conhecimento científico levantaram dúvidas sobre as ideias da criação divina e do surgimento da vida por mecanismos não reprodutivos. Em meados do século XIX, experimentos científicos ocasionaram alterações no entendimento sobre a origem dos seres vivos. Marque a alternativa que contempla o experimento que forneceu evidências irrefutáveis de que os seres vivos surgem somente pela reprodução de seres da mesma espécie.
Answer:
Tiger with lion.
Explanation:
Living beings arise only through the reproduction of beings of the same species. For example, tiger did not mate with lion because both are different species. Tiger can mate with their female tiger and produce fertile offspring while the lion only mate with their female lion and produces fertile offspring which belongs to the same species so we can conclude from this discussion that living beings formed only reproduction of same species.
Describe how the plasma membrane controls what goes into and comes out of a cell
Answer:
The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. Passive transport does not require energy molecules and happens when a funnel opens in the membrane, letting molecules flow through.
which of the following is a complementary base pair ?
A . guanine - thymine
B . guanine - guanine
C . adenine - cytosine
D . guanine - cytosine
Answer:
D is the anwser
Explanation:
I took the test and the answer was Guanine and cytosine!
A complementary base pair in DNA is guanine-cytosine (Option C).
The deoxyribonucleic acid (DNA) molecule is a double helix composed of two long (polynucleotide) opposite chains that are held together by hydrogen bonds.
In DNA, there are four types of nucleotides, each having one different nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).
According to the base pair rules, Guanine always pairs with Cytosine by three hydrogen bonds, whereas Thymine always pairs with Adenine by two hydrogen bonds.
In conclusion, a complementary base pair in DNA is guanine-cytosine (Option C).

Why do continents rise above the ocean floor?
Answer:
This increase is linked to the continental crusts rising above the oceans. ... As Earth's land plates began to shift and move, less dense rock may have been forced upward, shaping the continents we see today on Earth's crust.

21. Newton's first law of motion states that an object stays in constant motion unless a(n) ____ force acts on it.
Answer:
Outside
Explanation:
Newton's First Law of Motion states that a body at rest will remain at rest unless an outside force acts on it, and a body in motion at a constant velocity will remain in motion in a straight line unless acted upon by an outside force. ... Outside forces are sometimes called net forces or unbalanced forces.

How do stressed corals respond to disease?
Answer:
Much of the time, microorganisms as of now exist in the wild, and as corals become focused from human as well as common unsettling influences, their safe framework is debilitated and they are thusly more defenseless to illness.
Explanation:
Answer:
Brainliest pls!
Explanation:
In many cases, pathogens already exist in the wild, and as corals become stressed from human and/or natural disturbances, their immune system is weakened and they are therefore more susceptible to disease.

From the information that two atoms have two different proton counts, you can conclude that the atoms _____.
a - belong to two entirely different elements
b - represent different isotopes of one element
c - are likely to react violently with each other
d - might be different ions of the same element
Taking into account the constitution of an atom and the definition of atomic number, the correct answer is option a. From the information that two atoms have two different proton counts, you can conclude that the atoms belong to two entirely different elements.
AtomAn atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.
Every atom consists of a nucleus in which neutrons and protons meet and energy levels where electrons are located.
In other words, the atomic nucleus is the central part of the atom that is made up of protons and neutrons, while the orbitals or peripheral region is an area where electrons are found.
Atomic numberAtoms of different elements have different amounts of protons. The atomic number (which is identified by the letter Z) indicates the amount of protons that is present in the nucleus of an atom.
This number is then responsible for defining the electronic configuration of the atom and the chemical properties of the element. Then it is possible to say that the atomic number Z determines its identity.
This caseFinally, the correct answer is option a. From the information that two atoms have two different proton counts, you can conclude that the atoms belong to two entirely different elements.
