Answer:

Option A , 10 %

Explanation:

Only 10% of the energy is passed on to each trophic level of an energy pyramid. This is because most of the energy available at any trophic level is used by an organism in internal bodily activities like  cell respiration, ATP production, several life processes, metabolism etc. Thus, even though a large amount of energy is taken at a trophic level, nearly 90% of it is used by the organism itself and thus only 10% of the total energy is available for passing onto the next level. This is the reason why organism at the apex of an energy pyramid receives  the least energy.

The region of a Drosophila embryo with a low concentration of bicoid protein will develop into the _____. a) abdomenb) male flow
joja [24]

Answer:

The correct option is d) head.

Explanation:

Bicoid protein works as a transcription factor. It enters the nuclei of the embryos in early segmentation, where it activates the hunchback gene. In Drosophila, embryonic development begins at the time of fertilization. The sperm enters the mature oocyte through the micropile, a structure located in what will be the anterior region of the egg. Bicoid and hunchback mRNAs, protein products are critical for the formation of the head and thorax. Already in the early stages of oocyte development, certain mRNAs are located in specific regions of the oocyte: mRNA molecules encoding the Bicoid protein are preferentially located in the anterior region of the oocyte. Moderate levels of the bicoid protein are necessary to activate the formation of the thorax (i.e., the expression of the hunchback gene) but the formation of the head requires high concentrations of Bicoid, the promoters of a specific gap gene of the head must have sites of low affinity binding for Bicoid, so that this gene can be activated only in extremely high concentrations of Bicoid.

The lack of Bicoid protein affects the formation of the head and other structures in the anterior region of the oocyte.

Olenka [21]

Answer is hypertonic.

The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is concern for all living things, especially in in organisms lacking cell wall, <em>Paramecium</em> is one such protozoan. It has specialized structures called contractile vacuoles. A contractile vacuole collects excess water from the cell and release it out, keeping the cell from lysing as it takes on water from extracellular environment which hypotonic (a lower osmolarity than the cell’s cytoplasm) as compared to hypertonic environment inside <em>Paramecium</em>.

Which molecules would dissolve well in oil
Romashka-Z-Leto [24]

Answer: A variety of substances will dissolve oil, including gasoline and carbon tetrachloride -- both of which have non-polar molecules. Acetone is a special class of solvent called “dipolar aprotic” that, depending on the circumstances, can act as a weak acid or base; it dissolves oil and mixes with water as well.
