Explanation:
Diffusion is directly proportional to the Kinetic energy possessed by the particle.
More the Kinetic energy, more the energy.
Temperature directly influences the Kinetic energy -- or energy of motion -- of the molecules in a fluid. Molecules with greater Kinetic energy diffuse faster; in other words, the rate of diffusion increases as Kinetic energy increases.
Particles in all state of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the Kinetic energy and speed of particles; it does not weaken and forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures.

The speed of evaporation _____.
decreases as temperature decreases
increases as temperature increases

A wheat plant that is light green in color is found growing in a field. Biochemical analysis reveals that chloroplasts in this plant produce only 50% of the chlorophyll normally found in wheat chloroplasts. Propose a set of crosses to determine whether the light-green phenotype is caused by a mutation in a nuclear gene or in a chloroplast gene.
Answer:
Set of crosses:
Wild-type male x light-green female
Light-green male x wild-type female
Explanation:
Chloroplast genes are inherited maternally and, therefore it would be expected to observe this mode of inheritance:
- Wild-type male x light-green female >> offspring 100% light green
- Light-green male x wild-type female >> offspring 100 % wild-type
Moreover, nuclear genes are inherited from both parents, and, therefore, in the case of complete dominance, it would be expected to observe the following results:
1- When wild type is dominant:
- Wild-type male x light-green female >> offspring 100% wild type
- Light-green male x wild-type female >> offspring 100% wild-type
2- When light-green is dominant:
- Wild-type male x light-green female >> offspring 100% light-green
- Light-green male x wild-type female >> offspring 100% light green
Astronauts on a spaceship in outer space notice their instruments detect energy from the Sun. Which of the following provides evidence that the Sun’s energy is moving through outer space?
A. Molecular collisions of visible light and infrared radiation
B. Electromagnetic radiation in the form of radio waves
C. Electromagnetic radiation in the form of matter
D. Molecular collisions of gas atoms
The statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.
What do you mean by Radio waves?Radio waves may be defined as electromagnetic waves enclosing a wavelength between 1 millimeter and 30,000 meters, or a frequency between 10 kilohertz and 300,000 megahertz. These waves are used in radio, television, and satellite communications.
The Sun's energy consists of UV radiations but these radiations are not consumed by radio waves, resulting in the consumption of electromagnetic radiation on the Earth's surface.
Therefore, the statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.

Which compound forms when carbon dioxide diffuses and reacts with seawater?
A. Hydroxide ions
B. Carbonate
C. Bicarbonate
D. Carbonic acid
Answer:
It's D
Explanation:
When CO2 reacts with water first carbonic acid is produced. then this carbonic acid will transform to H+ and HCO3-.
BUT BECAUSE FIRST CARBONUC ACID IS PRODUCED SO CARBONIC ACID IS CORRECT.

If a woman has both alleles in her body cells, what will her eggs contain?
If a woman has both alleles in her body cells, then her eggs will contain only one of the alleles. This is because during the formation of eggs, a process called meiosis occurs, which randomly separates and distributes the alleles to the daughter cells. Therefore, each egg will contain one of the two alleles that the woman carries.
What is allele ?An allele is a variant form of a gene that is responsible for the expression of a particular trait or characteristic of an organism.
If a woman has both alleles in her body cells, it means that she is heterozygous for that particular gene. This means that she has two different versions (alleles) of the gene, one inherited from each parent.
During the process of meiosis, which produces eggs, the two alleles will segregate, meaning that each egg will receive only one allele.
The allele that ends up in each egg is random and depends on the particular orientation of chromosomes during meiosis.
So, the woman's eggs will each contain one of the two alleles she carries, and there is a 50% chance that each egg will contain either allele.

There are four mechanisms that can cause changes in the frequencies of genes in populations: mutation, migration, genetic drift, and natural selection. All four are mechanisms of evolutionary change. What is genetic drift?
A) In a population, it is the changes in allelic frequencies of a gene that are due to chance.
B) A random error/change in the DNA sequence. These may be inherited or occur in cells during the lifetime of the organism
C) Also known as gene flow. It is any movement of individuals and/or the genetic material they carry, from one population to another.
D) There is variation in any population differential reproduction occurs and over time a more advantageous trait exists in the population.

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.
