4. What was the most significant geologic event of the Mesozoic?
The most significant geological event of the Mesozoic era was the break up of a supercontinent. The correct option is D.
What was the geologic event of the Mesozoic era?The most significant geologic event of the Mesozoic era was the breakup of the supercontinent Pangaea into smaller landmasses, which began in the Late Triassic period and continued throughout the Jurassic and Cretaceous periods.
This led to the formation of the modern-day continents and oceans, as well as significant changes in climate, sea levels, and biotic diversity. The breakup of Pangaea also resulted in the formation of numerous mountain ranges, including the Rockies, Andes, and Alps, as well as the opening of the Atlantic Ocean.
These geologic events had a profound impact on the evolution of life on Earth, including the diversification of dinosaurs and the rise of mammals.
Therefore, the correct option is D.

Which is used to produce proteins?
Plasmids
Ribosomes
Pili
Cell Wall
Flagella
Answer:
Ribosomes
Explanation:
Ribosomes are organelles with the main purpose of protein synthesis in cells, both in eukaryotes and prokaryotes.
Ribosomes create proteins through translation of mRNA, and the linking of amino acids.
These linked amino acids are the proteins, which can also develop into more complex types of protein structures, such as tertiary and quaternary structures.
So, the correct answer is Ribosomes.

A scientist separates a population of lizards into two groups. What would
most likely increase the rate of speciation in this population?
A. Have one group breed twice as often as the other.
B. Keep the two groups apart, but in identical ecosystems.
C. Force the two groups to breed with each other.
D. Have one group live with a much stronger predator.
Answer:
Hi, there your answer is D. Have one group live with a much stronger predator.
Explanation:
Having one group live with a much stronger predator will most likely increase the chances of speciation.
What is speciation?It is a process by which a new species of an organism is created.It occurs due to evolution.It occurs when a portion of population gets separated from the original population and evolves different characters that are heritable.Will speciation occur if :one group breeds twice as often as the other? No, because no selective force is acting on it.both groups are in identical ecosystem? No, since no reason for adapting and evolving a new character will be there.both groups interbreed? No, there is no competition, no struggle for existence and hence no evolution occurs.one group lives with a strong predator? Yes, since they will evolve evasive mechanisms and characters.To learn more about species, evolution, and predator here,

Explanation:
What are valence electrons?
A. the atomic mass
B. the atomic number
C. all of the electrons in an atom
D. electrons in the outermost energy level
Answer:
D
Explanation:
The simple answer is the electrons in the outermost energy level.
Hydrogen has 1 electron in the outermost energy level.
Magnesium has 2 so this tells you that magnesium has a charge of 2
Oxygen has 6 oxygen has a charge of - 2
Fluorine has 7
For most elements, the electrons in the most outer ring determine the valence of the element.
Notice that the non metals work differently than the metals. Mg may have a charge of 2 and that is the number of electrons in the valence right.
Oxygen is a non metal it has a charge of - 2. It gets 6 electrons by subtracting the number of its charge from 8.
Answer:
D. electrons in the outermost energy level
Explanation:
The valence electrons are the electrons in the outermost energy level.
Why did Gregor Mendel choose to use purebred plants in his experiments?
A They reproduce sexually.
B They exhibit only one form of a trait.
C They have a variety of traits.
D They reproduce asexually.
Answer:
B
Explanation:
Gregor Mendel chooses to use purebred plants in his experiments because they exhibit only one form of a trait. The correct option is B.
What is Mendel's experiment?Mendel altered pure pea plant lineages. First-generation hybrids (F1) displayed dominant qualities like purple flower color while hiding recessive traits like white bloom color.
But in second-generation (F2) pea plants, recessive characteristics returned in a 3:1 ratio (dominant to recessive). Every pea plant has both male and female reproductive organs, and they all typically procreate by self-pollinating.
This was crucial to make sure that there were no other factors influencing the result of the cross when he crossed two plants with different features.
Therefore, the correct option is B, They exhibit only one form of a trait.

The overall process of photosynthesis can be written as the equation:
A. 6 glucose + 6 water --> 6 oxygen + 6 carbon dioxide + light
B. 6 water + 6 carbon dioxide (+ light) --> 6 oxygen + glucose
C. 6 oxygen + 6 water (+ light) --> 6 glucose + carbon dioxide
Answer:
B. 6 water + 6 carbon dioxide (+ light) --> 6 oxygen + glucose
Explanation:
Remember that in a chemical equation the reactants (input) are on the left and the products (output) are on the right. For photosynthesis to occur 3 different reactants are needed: water, carbon dioxide, and light. Note that because the light is not an element or molecule, it is sometimes written in paratheses or left out of the equation. Then, the products are glucose, which is the intended product, and oxygen, which is an unintentional byproduct that is released back to the atmosphere. Additionally, the equation for cellular respiration is the opposite of this, with the products as reactants and vice versa (except ATP is switched in for light).

Use mathematics to calculate how much of the energy is left in the third trophic level? if each level in a food chain typically losses 90 percent of the energy it takes in and the producer level uses 1000 Kcal of energy.
Answer:
10 kcal.
Explanation:
The third trophic level receives 10 Kcal from the second trophic level while on the other hand, 90 Kcal energy releases in the atmosphere in the form of heat energy. The producers has 1000 Kcal energy from which only 100 Kcal is transferred to the primary consumer or second trophic level while the remaining 900 Kcal releases in the form of heat energy in the atmosphere and then only 10 Kcal energy is transferred to third trophic level while the remaining 90 Kcal releases in the atmosphere.

Natural selection is a change in species to adapt to environmental change with heredity variations, hence option b is correct.
What is natural selection?The development of a population's heritable features across generations is a fundamental process of evolution.
Natural selection requires the occurrence of four factors: reproduction, inheritance, variation in organism fitness, and variation in individual traits among population members.
Natural selection happens spontaneously if they are satisfied. Neutral evolution, or random walk, is the most well-known method of evolution that has been identified that does not involve natural selection.
Therefore natural selection organisms' fitness, and variation in individual traits among population members, hence option b is correct.
