Answer:

The question is not well structured, the correct one is;

Look at the following statement. What word completes the second gap? Substances move by active transport from an area where they are __________ concentrated to an area where they are __________ concentrated

The answer is MORE

Explanation:

Substances move from one position to another in living systems. This movement of substances can either be passive (without energy) or active (require energy). Active transport of substances involves the movement of substances against their concentration gradient.

Ideally, substances move naturally from an area they are more concentrated to an area they are less concentrated but in active transport, the opposite occurs i.e. substances move from area that they are less concentrated to one that they are more concentrated, which is going up against the normal concentration slope/gradient. Due to this, energy in form of ATP is usually required by the cell to perform active transport unlike passive transport that occurs without energy input.

Exanples of active transport in living cells are exocytosis and endocytosis in some organisms. Based on this explanation, the first gap will be LESS while the second gap will be MORE.

_____ communicate information in the opposite direction, from the brain and nervous system to muscles and glands.
yulyashka [42]

Answer:

The correct answer would be efferent neurons.

Efferent neurons are the motor neurons which communicate information in the opposite direction as compared to the afferent neurons, that is, they communicate information or response impulses from the brain or central nervous system to the muscles or glands.

The response impulses results in the movement of the muscles or activation/deactivation of certain gland

In contrast, afferent neurons are the sensory neurons which carry impulses from the receptors to the central nervous system.

Aristotle defines a virtue as a(n) __________ that requires __________.
DENIUS [597]

Aristotle illustrates virtue in a way distinct from what one is usually taught in school, but it is much closer to how one thinks on a regular basis. One is usually taught that courage is the contrary of cowardice, and generosity is the reverse of miserliness and others.  

Although, Aristotle illustrates virtue as the mean between the two extremes, which requires to be avoided. For Aristotle, virtue is the golden mean between the two extremes. Though the mean is not a strict arithmetic mean. Virtue comes in between the two extremes, but where it actually comes depends on a very large extent to a particular situation.

Phoenix [80]

Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducing an immune response and then has a subsequent exposure to the same antigen. The sensitization phase is characterized by <u>Induction of a CD4 T cell type II immune response</u>.

The process by which your body becomes sensitive to a particular substance is called sensitization. When your immune system becomes sensitized to an allergen, you can develop certain symptoms.

Antigens that can induce an allergic response are called allergens, and they are often derived from non-infectious or non-microbial sources.

Restriction endonucleases are especially useful if they generate sticky ends. What makes an end sticky?
Mazyrski [523]

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

A) single-stranded complementary tails

B) blunt ends

C) poly-A sequences

D) 5' cap

E) interference

Answer:

A) single stranded complementary tails

Explanation:

Restriction endonuclease is the enzyme which cuts the DNA sequence in the internal sequence.

The endonuclease enzyme can cut the DNA sequence in a way that it can form the cuts with the single-stranded overhangs called sticky ends and without overhangs called blunt ends.

The sticky ends are produced when the enzyme makes cut at the single strand and then makes the cut at between the same base at the nitrogenous base. This type of asymmetrical cut forms the single-stranded overhangs which can form the complementary base pairs easily.

Thus, Option-A is correct.

Single-celled eukaryotes arose from prokaryotes. Later, which larger, more complex organisms did they evolve into?
sdas [7]
A l,ll,lll and lV would be the answer because a eukaryote is an organism with complex cells, or a single cell with a complex structures. In these cells the genetic material is organized into chromosomes in the cell nucleus. Animals, plants, algae and fungi are all eukaryotes. There are also eukaryotes amongst single-celled protists.
