Which of the following correctly compares steroid and nonsteroid hormones              a.  nonsteroid hormones enter the nucleus and affect protein synthesis while steroidal hormones do not.    b.  neither steroid nor nonsteroid hormones enter the cell membrane.    c.  steroid hormones bind to receptors on the outside of the cell and rely on secondary messengers while nonsteroidal hormones do not.    d.  steroid hormones enter the nucleus and affect protein synthesis, while nonsteroidal hormones do not.

D. Steroid hormones enter the nucleus and affect protein synthesis, while nonsteroidal hormones do not.

Explanation:

Steroid hormones are synthesized from lipids, such as cholesterol. They are fat soluble and thus can enter the nucleus and affect protein synthesis.

Non-steroid hormones are synthesized from amino acids. They are water soluble and thus cannot enter the nucleus of target cells. Instead, a non-steroid hormone binds to receptors on the outside of the cell and rely on secondary messengers.

The correct answer is option D.

Explanation:

Steroid hormones are basically are lipid-soluble molecules and derived from cholesterol. Steroid hormones pass through cell membranes because they're lipid soluble, and attach to a receptor that is present inside the cell, entering the nucleus, binding to DNA, and beginning gene transcription and translation and produce protein.

Nonsteroid hormones are water soluble hormones that do not enter the cell membrane but bind to cell membrane receptors that produce a chemical signal inside the target cell.

Thus, the correct answer is option D.

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
