Answer:

Both cones and rods participate in dark adaptation, slowly increasing their sensitivity to light in a dim environment. Cones adapt faster, so the first few minutes of adaptation reflect cone-mediated vision.

MatroZZZ [7]

The question is incomplete as it does not have the options which are:

artificial

enhanced natural

extraterrestrial

manmade

Answer:

Enhanced natural resources

Explanation:

Natural resources are the resources used by the humans for survival present in the environment or provided by the surrounding environment.The natural resources includes the wood, gas, air, water and other substances.

The substances which emits harmful radiations like radium, thorium, uranium are known as radioactive isotopes.

When these ionizing radiation emitting natural substances increases in the environment due to human activities like the particle accelerators, X-rays and other methods which produces these substances then these substances are refereed to as the enhanced natural substances.

Thus, Enhanced natural resources is the correct answer.

AveGali [126]

Answer:

What is the indicator we are using in this titration?

a deep blue indicator

Explanation:

What is the indicator we are using in this titration?

a deep blue indicator

the purpose of grinding the spirulina is to be able to break the cell into smaller particles that can dissolve well in a solution.

when powder spirulina is mixed with silica the cells are easily break even.

Should the ground silica and spirulina mixture be suspended in deionized water, exhibit water, or buffer? Why?

ground silica and spirulina mixture be suspended in deionized water because its dissolved and mixed well in water than any other solvent.

What is the color of the folded phytobilliprotein with the bound cofactor?

A blue color is observed when phytobilliprotein is folded.

How do you expect it to change as you add acid or base?

when a base solvent is use for the solution of silica and spirulina (e.g of base NaOH) is used, the colour obseved will be pale yellow or green color.

when a acidic solvent is use for the solution of silica and spirulina (e.g of base HCL) is used, the colour obseved will be colorless solution.

When a base and acidic solvent is used, it causes a changed in the charge state of the protein and changes the interaction thereby causing unfolding.

murzikaleks [220]

Answer:

Explanation:

TransA can be found in the plasma membrane, while TransB is found in the cytoplasm, according to the immunofluorescence localization test analysis. There are two main varieties of serotonin transporters in the neural system when it comes to serotonin signaling.

An intracellular transporter that carries and delivers serotonin throughout synaptic vesicles.
A transmembrane transporter that prevents hyperactivity overstimulation by re-uptaking serotonin from the synapse.

Therefore, suppose we compare this signaling pathway model to the analyzed experimental test. We can vividly acknowledge that TransA acts as a serotonin reuptake transporter since it is present in the plasma membrane of nerve cells and TransB is a serotonin vesicle transporter that is present and located in the cytoplasm. As a result, the majority of TransB is speculated to be present in synaptic vesicle membranes.

</span> All normal eggs from the mother have an X chromosome while usually half the sperm cells from the father have a Y (male) chromosome and the other half have an X (female) chromosome and it is therefore the father's sperm that dictates which gender the embryo will take.

If the egg is fertilized by a sperm with a Y chromosome then the embryo will be a genetic male due to XY chromosome combination.
