Answer:
One characteristic that describes sexual reproduction and that is not present in asexual reproduction is the combination of genetic information from two parents.
Explanation:
Sexual reproduction involves the participation of two individuals, whose genetic material is contributed and when they unite they give birth to a new individual, through the process of fertilization.
Individuals who reproduce sexually have the ability to form cells with half of their genetic charge, called gametes. The union of these cells forms the zygote, from which a new individual develops.
In asexual reproduction, a single individual is responsible for the reproductive process, which occurs by
Gemination. Bipartition Fragmentation. Parthenogenesis. Sporulation or sporogenesis.Each one of these processes represents a different type of reproduction than the one that occurs sexually.

Which of the following allows for water molecules to have high surface
tension?
strong covalent bonds between water molecules
weak ionic bonds between water molecules
weak hydrogen bonds between water molecules
strong hydrogen bonds between water molecules
Submit
Answer:
Among common liquids, water exhibits a distinctly high surface tension due to strong hydrogen bonding between its molecules. As a result of this high surface tension, the surface of water represents a relatively “tough skin” that can withstand considerable force without breaking. A steel needle carefully placed on water will float.

There is a certain type of fish in a lake. Fisherman can catch the largest of these fish using nets. They don't like the little fish and most of the smaller ones can get through the holes of the nets. After a few decades of this type of fishing, how do you think the fish population may change? Use the ideas explored in this article to give an explanation for your answer.
Answer:
After a few decades, there will be only small fishes, as directional selection will be acting in this population.
Explanation:
Directional selection increases in the proportion of individuals with an extreme phenotypic trait. Individuals expressing the other phenotypic extreme might be receiving different pressures that drive them to decrease their fitness. These pressures, in general, might be related to food access, niches availability, reproduction, predation, among others.
In this example, there are two extreme phenotypic traits, large and small fishes. Large fishes are being predated by fishermen, who prefer large individuals rather than small ones. Large fishes fitness start to decline, as they are being hunted. Only small fishes get to survive, they get to reproduce and hence, to have better fitness. Natural selection is acting on the size of these animals, favoring the small-sized ones. Over a few decades, the directional selection will increase the proportion of small fishes.
There are certain types of fish in the lake that the fishermen can catch using the nets. As they don't like the small ones which get out of the holes of the net.

Question 4 of 10
Which of these events could be a result of an error made during
transcription?
A. The next generation of the organism inherits the error
B. The mRNA produced has a different base sequence
C. A carbohydrate is produced instead of a protein
D. The gene used to produce the mRNA is altered
Answer:
B. The mRNA produced has a different base sequence
Explanation:
Transcription is the process in which mRNA is transcribed from DNA, which is then translated into a protein.
An error made during transcription does not alter the sequence of the DNA. Therefore, the gene itself is not altered and the error is not passed on to the next generation.
Carbohydrates are never produced by transcription and translation, which produce polypeptide chains which from mature proteins.

In poultry, black is dominant to white, but the heterozygote is blue. If you consistently
eliminated the black and white birds which appear in your flock of Blue Andalusians, how many
generations of such selection would it take to produce a true breeding flock of Blue
Andalusions?
Answer:
indeterminate
Explanation:
The answer would be an indeterminate number of generations.
The blue trait is a heterozygous trait. In other words, the blue allele does not really exist. Two different alleles team up to produce the trait, whereas, only two the same allelic conditions can produce a true-breeding flock.
Hence, it will take an indeterminate number of generations to produce a true-breeding flock of the Blue Andalusions.

The products of Photosynthesis are the reactant of cellular respiration. So, the correct option is (B).
What is Cellular respiration?Cellular respiration is defined as the process by which organic fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy to drive the bulk production of ATP.
It works in the presence or absence of oxygen. But crucially, the process is called cellular respiration because the cell "respires" in a way that takes in molecular oxygen (as the electron acceptor) and releases carbon dioxide (as the end product).
The cellular respiration is represented as
[tex]C_6H_1_2O_6 + 6O_2 ---- > 6CO_2 + 6H_2O[/tex]
Their reactant are the products of Photosynthesis.
So, the products of Photosynthesis are the reactant of cellular respiration. So, the correct option is (B).

The answer can be given as:
tRNA Anticodons - UAC Amino Acids- methionine Number of Water Molecules Produced -0In the translation, the mRNA sequence is decoded to produce the anticodons within the ribosomes. The translation of amino acids starts with the starting code AUG. The tRNA anticodon complementary to the mRNA will produce UAC.
In RNA, thymine is replaced by uracil, which is complementary to adenine. Thus, the UAC codes for methionine will be formed.

4. What is the mass of N2H4 gas in a 350.0 mL container at 50.0 °C, if the pressure of the gas is
885.0 torr?
Answer:
0.36g
Explanation:
Given parameters and conversion to standard unit
To solve this problem we must assume ideality
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = [tex]\frac{760}{885}[/tex] = 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n = [tex]\frac{PV}{RT}[/tex]
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = [tex]\frac{0.86 x 0.35}{0.082 x 323}[/tex] = 0.01mole
So,
Mass = 0.01 x 32 = 0.36g
