Answer:

The correct answer is option d, that is, the star's absolute magnitude.

Explanation:

The Hertzsprung-Russell diagram or the H-R diagram also called the color-magnitude diagram. It demonstrates the association of the color of the stars (temperature) with the luminosity of the star or absolute magnitude. The stars apparent magnitude at a distance of ten Parsec from Earth is known as the absolute magnitude of the star.

KonstantinChe [14]

A nerve is actually a long threadlike bundle of dendrites that conduct electrical impulses.

<span>Dendrite word derived from the Greek word ‘dendron’ which means tree. They carry messages in the form of electrical impulses to cell body, there are also wire like nerves called axon. Sensory nerves and motor nerves are common types of nerves.</span>

Drinking alcoholic or caffeinated beverages increases urine output more than drinking an equivalent amount of water.
olga2289 [7]

Answer:

A) ADH secretion decreases. B) Urine osmolarity decreases.

Explanation:

Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.

A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.

B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.

I hope this answer helps.

Explanation:

Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.

During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.

Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.

Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs.  In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.

Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.

Which of the following is an example of adhesion in organisms
12345 [234]

Adhesion is defined as a component of water ,  an attraction that occurs between two different substances like water and the cell walls of plant cells.

For instance:

 A tree requires to be able to transport water  from the roots to the leaves atop the tree over a long distance. The Water molecules will stick to the xylem in the method called as adhesion.
