G proteins, also known as guanine nucleotide-binding proteins, are a family of proteins that act as molecular switches inside cells, and are involved in transmitting signals from a variety of stimuli outside a cell to its interior. ... G proteins belong to the larger group of enzymes called GTPases.

Answer:

A repressor is a regulatory protein that may bind DNA to inhibit transcription. An operator is a DNA sequence that binds a regulatory protein. A promoter is a DNA sequence that binds RNA polymerase and regulates transcription. A corepressor is a compound that interacts with another protein or compound to form an active repressor. An inducer is a compound that induces or activates transcription, such as lactose.

Explanation:

Repressor proteins bind to DNA and RNA to suppress target gene expression. A DNA repressor blocks transcription by inhibiting the attachment of RNA polymerase to the promoter sequence, while an RNA repressor bind to the mRNA to block translation of the protein. An operator is a DNA sequence required for the attachment of transcription factors. The genes that are transcribed by the binding of a transcription factor to an operator sequence are collectively referred to as an operon. Operons are generally found in prokaryotes but they also can be found in some eukaryotes including Caenorhabditis elegans and Drosophila melanogaster. An inducer is a molecule that activates gene transcription either by binding to repressors/corepressors (thereby inactivating their functions) or by binding activators. For example, the allolactose act as an inducer of the lac operon.

Answer:

eutrophication

Explanation:

Eutrophication refers to a situation in which the aquatic environment becomes excessively enriched with nutrients. This leads to algal blooms in aquatic habitats such as lakes. These nutrients come from Fertilisers used in farming, which find their way into water bodies through run-off thereby increasing nutrient levels.

Excess nutrients causes phytoplankton to grow and reproduce at an alarming rate resulting in algal blooms. This bloom disrupts the balance in the ecosystem leading to many problems.

The algae may end up using all the oxygen in the water, causing oxygen shortage for aquatic life. Some of the algae may die, their decay may lead to further oxygen depletion. As oxygen is depleted, aquatic organisms may also begin to die.

This question is incomplete; here is the complete question:

All of the following are examples of organic matter soil except

A. Decaying plants

B. Bacteria

C. Fungi

D. Water

The answer to this question is D. Water

Explanation:

Organic matter derives from living beings, due to this, organic matter is considered as a biological product. In this context, materials such as decaying plants are organic matter because they derive from living organisms and contain biological molecules (most contain carbon). This category does not apply to water, which is composed of hydrogen and oxygen and does not derive from living beings. Thus, the one that is not organic matter is water.

Answer:

D. Water

Answer:

The correct answer is atrophy

The correct answer is C. Its neighborhood is not clear.

Explanation:

One of the key features of a planet is that it clears its neighborhood; this means the planet gravitational force is strong enough that there are no other celestial bodies on its orbit or next to it except by its moons or satellites. This does not occur in the image presented because there are smaller celestial bodies near to the main or bigger celestial body. This likely occurs if the celestial body is not big enough to clear its neighborhood, and therefore it is not a planet.

Answer:

i think that the answer is B. Hamilton County on the plains of central Texas i took the test

Explanation:

Hamilton County on the plains of central Texas is least likely to experience a volcanic eruption. Therefore, option (B) is correct.

Molten rock and gases stored under the surface erupt through a volcano, generating a hill or mountain.

Active, inactive, or extinct volcanoes. Active volcanoes are likely to erupt again. Dormant volcanoes may erupt again. Extinct volcanoes won't erupt.Magma collects inside active volcanoes. The magma chamber's pressure forces it through rock channels and onto the planet's surface.

Volcanic eruptions can be violent or slow-moving. Volcanoes erupt through vents on the sides or a primary entrance at the top. The volcano's morphology depends on eruption rate and magma chemistry. Land and sea volcanoes exist. As lava cools and hardens, underwater volcanoes build mountains and ranges. When volcanoes rise above the ocean, they create islands.

Answer:

The correct answer is intragenic suppressor mutation.

Explanation:

A suppressor mutation partially or completely converses the effects of a different mutation. A suppressor mutation is of two kinds, that is, an intragenic suppressor and an intergenic suppressor. An intragenic suppressor converses the influence of a mutation at a distinct site in a similar gene.  

On the other hand, an intergenic suppressor converses the influence of a mutation at a distinct locus of the gene. It is the intragenic suppressor mutation, which takes place in a similar gene where the occurrence of the first mutation had taken place. Therefore, the mutation, which hides the influence of another mutation at a location, which is different from the location of the original mutation, but taking place in a similar gene can be illustrated as the intragenic suppressor mutation.  

Answer:

C: It does not show that photosynthesis consists of many separate steps.

Explanation:

Photosynthesis is a unique process carried out by the cells of autotrophic organisms. It is the process whereby they synthesize their own food in form of sugars (glucose) in the presence of sunlight. Ideally, the photosynthetic process makes use of carbon dioxide (C02) and water (H20) in the presence of light energy (from sun) to produce glucose sugar (C6H12O6) and oxygen (02). The general photosynthetic equation is as follows:

6CO2 + 6H20 + light → C6H12O6 + 6O2

However, the process is not as simple as portrayed as it involves many separate steps that collectively forms the photosynthetic product (glucose). Photosynthesis occurs in two major stages namely: light stage and light independent stage, which in turn consists of series of reactions that forms the products.

Therefore, the equation attached to this question describes photosynthesis but It does not show that photosynthesis consists of many separate steps.

Answer:

b) the plastic bag was permeable to iodine

the plastic bag was selectively permeable

the iodine moved into the plastic bag.

the plastic bag was permeable to cornstarch.

Explanation:

The experimental set up represented the concept of osmosis.That is  the movement of water  molecules from the region of higher  water potential to region of lower water potential through a semipermeable membrane(a  cell membrane which only allows water and certain molecules to pass through,but restrain other molecules through its pores.

Generally potassium iodine test is the standard test for starch.

Therefore, in the question,water moves iodine molecules as iodine solution(from high water potential) to move across the paper bag(semi permeable membrane) to the reach the corn solution.(low water potential,high solute potential).This turns the starch in the corn solution  blue-black/purple.

If the solution in the plastic bag turned dark purple:

To test for the presence of starch in a solution, iodine solution is used. This gives a blue-black coloration which occurred due to the formation of a starch-iodine complex.

From the above experiment, the plastic bag which contains the corn starch solution, separates the solution from water containing 10 drops of iodine.

The turning of the solution, inside the plastic bag, into blue black signifies the formation of starch-iodine complex between the cornstarch solution the iodine water.

The reaction was able to occur because the plastic bag, which is selectively permeable to iodine, allowed the movement of iodine from the beaker of water into it. This is called diffusion.

Therefore, if the solution in the plastic bag turned dark purple it means that the plastic bag which is semi permeable allowed the movement of iodine into it.

Answer:

The question is incomplete, below is the completed question:

The main function of a cell membrane is to allow substances to enter and leave the cell. Which is a correct description of transport through a cell membrane ?

a. Diffusion, or passive transport, occurs when molecules diffuse from a lower concentration to a higher concentration.

b. Facilitated transport occurs when proteins that extend through the cell membrane provide a channel through which certain substances can diffuse more rapidly than by passive diffusion.

c. The lipid bilayer opens up and allows the ions or molecules to enter the cell, then closes.

d. Active transport occurs when molecules diffuse from a higher concentration to a lower concentration.

Answer:

b. Facilitated transport occurs when proteins that extend through the cell membrane provide a channel through which certain substances can diffuse more rapidly than by passive diffusion.

Explanation:

Transport through cell membranes can be broadly classified as active transport or passive transport.

Active transport requires energy in the form of ATP for the transportation of substances across the cell membrane.

Option b correctly describes facilitated diffusion, which is a passive-mediated diffusion process, where channels in the cell membrane mainly composed of proteins called transmembrane integral proteins, allow for the movement of certain molecules (mostly polar/hydrophilic) molecules that will not otherwise be transported through simple diffusion because of the hydrophobic nature of the cell membrane.

The other options are wrong because:

a. diffusion or simple transport involves the movement of substances from regions of higher to a lower concentration not lower to higher as suggested here.

c. The lipid bi-layer does not allow ions or hydrophilic molecules because it is hydrophobic in nature, and it is not a channel, so it does not open and closes

d. In active transport, transfer of molecules is from regions of lower to higher concentration and not higher to lower concentration as suggested here.
