Answer:

A control in an experiment is a replica used to confirm that the results or changes in the dependent variable/s are caused by the independent variable values or treatments. There are different kinds of controls according to the experiment, for example,  no treatment can be applied, or for example in laboratory experiments, there are controls to check that the reactives function properly, making a replica with them but without the sample that is being measured.

The genotype of the Dad must be X^AY because that's the only possible genotype for a normal male.

The genotype of the mom must be X^AX^a because that's the only way to have a colorblind son while being a normal mom. The colorblind son gets a Y from his dad and X^a from his mom.

The genotype ratio among the children must be 25% heterozygous dominant, 50% homozygous dominant, and 25% heterozygous recessive.

The phenotype ratio among the children must be 75% normal and 25% colorblind.

The charge of the electrical impulses sent from stimuli is extremely positive. Thus, the correct option is A. The net charge of such electrical impulses is positive because of the positively charged ions of the Na+.

An electrical impulse may be defined as a nerve impulse that contains an electrical signal which travels throughout the body by the axon terminal.

In the resting potential state, the potential difference is -80mV, while after reaching the electrical impulse it changes to +40mV. This happens due to an electrical imbalance between sodium and potassium influx and efflux.

Therefore, the correct option is A.

Answer:

A trench would be formed, a ridge would develop, magma would be released and the crust would separate.

Explanation:

Look at the picture and try to identify the process. Once you have identified the process, think of the landforms formed and what processes are involved. The phrase "seafloor spreading" in the question tells us that this is an oceanic divergence process.

When two oceanic plates diverge (move apart), tensional forces are exerted. Fractures may occur (faulting) near the plate boundary. Magma rises at the zone of divergence (a large fracture between the two plates). It solidifies and builds up to form a mid-oceanic ridge, a central ridge dividing the ocean basin. The cooled magma forms a new sea floor between the diverging plates (sea floor spreading).

For your info, I only gave you the explanations for the options chosen and there are actually more landforms and processes that occur in oceanic divergence. If you want the full explanation of the entire process, let me know.

Explanation:

The advantage of cyanobacteria over alternate biofuels is that multiple processing steps can be avoided.

Cyanodiesel, a byproduct of cyanobacteria, has unlimited growth potential and are used in various fields of biotechnology.

⇒ Transform solar energy into chemical energy by the process of photosynthesis

⇒ Fixing of atmospheric nitrogen, helping in the increase of soil fertility

⇒ Widespread applications in pharmaceuticals and agriculture

The advantage of cyanobacteria to produce isobutanol over alternate biofuels is that multiple processing steps required in biofuel production from other sources can be avoided. So option B is correct.

Cyanobacteria are recently been engineered to produce a variety of chemicals, such as ethanol, Isobutanol, and Isoprene, directly from solar energy, carbon dioxide, and water. This makes cyanobacterium a potential new cell factory for the production of energy and chemicals to meet global energy and climate change challenges.

Synthetic cyanobacteria are engineered through heterologous biosynthesis to create value-added chemicals through photosynthesis. Several chemicals have been successfully generated in synthetic cyanobacteria.

Carbon moving and what is happening to the amount of carbon in the living things inside the aquarium is by photosynthesis.

An aquarium (plural aquariums or aquaria) is a vivarium, usually contained in a clear-sided container (typically constructed of glass or high-strength plastic) in which water-dwelling plants and animals (usually fish).

According to this question, the aquarium contains water, plants and fish. The glass of the aquarium is transparent and allows the passage of light. Plants are unique set of organisms that have the ability to produce their own food (organic molecule) using the energy from light which they absorb via the Chlorophyll pigment in their Chloroplast. This process carried out by plants is called PHOTOSYNTHESIS.

The amount of carbon in form of carbondioxide (CO2) decreases when the light was switched on in the aquarium due to the process of photosynthesis carried out by the plants.
