Explanation:
Each of the major hypotheses proposed to explain why sexual reproduction is more widespread than asexual reproduction ultimately bases its explanation on the adaptive benefit of:________.
a. forming large populations.
b. forming genetically distinct offspring.
c. reducing mutation rates.
d. forming relatively slow-growing populations.
e. forming gametes of different sizes.
Answer:
The correct answer is option b, that is, producing genetically distinct offspring.
Explanation:
It is found that sexual reproduction is more widespread in comparison to asexual reproduction primarily due to its adaptive benefit of producing offspring, which are genetically distinct. At the time of sexual reproduction, the genetic material of two individuals amalgamates to give rise to genetically-different offspring, which vary from their parents.
This tendency of reproducing sexually by the majority of eukaryotes is proof of its evolutionary success. The genetic diversity resulting due to sexual reproduction is considered to provide better chances of surviving in a modifying or unpredictable environment.
Water molecules diffuse through the cell membrane through aquaporins. How are these proteins helpful in osmosis?
Answer:
Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis
Explanation:
Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.
Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.
Aquaporins increase the rate of osmosis which is generally slow due to the polarity of water molecule.

What is ATP, how is it made, and what is its primary function in cells?
Answer:
ATP:Is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank.
How is it made:Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.
primary function in cells:Adenosine triphosphate, or ATP, is the primary carrier of energy in cells. The water-mediated reaction known as hydrolysis releases energy from the chemical bonds in ATP to fuel cellular processes.
EXPLAIN THE WATER CYCLE IN YOUR OWN WORDS
Answer:The water cycle is often taught as a simple circular cycle of evaporation, condensation, and precipitation. Although this can be a useful model, the reality is much more complicated. The paths and influences of water through Earth’s ecosystems are extremely complex and not completely understood.

Do you think the adaptation of the animal you chose are a result of its environment, genes, or both? Explain
Answer:
The adaptations are result of both the environment and genes. Animal develop adaptive characteristics in response to their environmental challenges. These adaptations help the animals survive in their environment. The animals are more likely to reach reproductive age. So,these adaptive traits are more likely to be passed on to offspring.In the case of cheetahs,tan coloring,conservation of water, and fast legs are traits that help them survive in the savanna. These traits,like all the other characteristics of cheetahs,are genetically passed from parents to offspring.

Which balances the equation Mg + O2 → MgO?
Mg + 2O2 → 4MgO
2Mg + 2O2 → 2MgO
2Mg + O2 → 2MgO
2Mg + 2O2 → 4MgO
Answer:
C
Explanation:
2Mg + O2 → 2MgO
got it right on edge 2020
Considering the law of conservation of matter, the correct answer is third option: 2 Mg + O₂ → 2 MgO
The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.
Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.
So, in the case of Mg + O₂ → MgO, you have:
Left side: 1 Mg and 2 O. Right side: 1 Mg and 1 O.The coefficients of each molecule below indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.
By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.
So, balancing the O to obtain the same amount in the reactants and products you get:
Mg + O₂ → 2 MgO
So you have:
Left side: 1 Mg and 2 O. Right side: 2 Mg and 2 O.
Since you still don't have the same amount of Mg on both sides, the equation is not balanced. Therefore, balancing the equation again:
2 Mg + O₂ → 2 MgO
So you have:
Left side: 2 Mg and 2 O. Right side: 2 Mg and 2 O.Now you have the same amount of each element on each side of the reaction, so the reaction is balanced.
Finally, the correct answer is third option: 2 Mg + O₂ → 2 MgO

Which most clearly shows evolutionary relationships between species?
Answer:
DNA, similar bone constructs, and simlar looks
Explanation:
Answer: Scientists collect information that allows them to make evolutionary connections between organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.
Two Measures of Similarity
Organisms that share similar physical features and genetic sequences tend to be more closely related than those that do not. Features that overlap both morphologically and genetically are referred to as homologous structures; the similarities stem from common evolutionary paths. For example, as shown in Figure 12.2.1, the bones in the wings of bats and birds, the arms of humans, and the foreleg of a horse are homologous structures. Notice the structure is not simply a single bone, but rather a grouping of several bones arranged in a similar way in each organism even though the elements of the structure may have changed shape and size.
