Answer:

DNA replication is said to be semi-consertive because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand.. Semiconsertive replication would produce two copies that each contained one of the original strands and one new strand.

Temperature and absolute brightness

Explanation:

The X-Axis of the diagram is heat, and it actually goes down in heat.

The Y-Axis is for brightness, and it works like a regular axis, meaning as it goes up, the number or unit of some sort, in this case luminosity, goes up.

Two characteristics are used to classify stars on the Hertzsprung-Russell diagram are temperature and absolute brightness

The Hertzsprung-Russel diagram or HR diagram is a graphical tool using a scatter plot used by astronomers to classify stars according to their:

Here, The HR diagram plots as either

Therefore two characteristics used to classify stars on the Hertzsprung-Russell diagram are temperature and absolute brightness(Luminosity)

Answer:

carbon atoms

Explanation:

all organic molecules have carbon.

Some properties like Polarity makes water a good solvent, cohesion helps in stick water molecule to itself while adhesion helps it to stick with other surfaces. Water have surface tension due to hydrogen bonding.

when two similar molecule come closer adhesion occur where as in cohesion two similar molecules face the force of attraction.

Adhesion is the force of attraction observed between the water molecules and xylem vessels while Cohesion is unrestrained among water molecules.

Capillary action and meniscus are the effects of adhesion while  Surface tension, meniscus and capillary action are the effects of cohesion.

The major forces responsible for adhesion are electrostatic or mechanical forces while Cohesion is the result of hydrogen bonding and Van der Waals forces.

A strong adhesion can lead to spread of liquid all over the surface while  cohesion forms water droplets.

Answer:

It's a row of chemical elements

Answer:

The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

Answer:

Forest.

Explanation:

Wood comes from forest which is used for building homes. The big source of wood are the forest present on hilly areas where woody plants such as pines are grown and cut down when they acquire a specific length and width. These woody plants are used to build houses and furniture etc. Wood has 20% higher strength to weight ratio than structural steel so that's why it is for building houses.

Answer:

Does the movement of molecules stop when the concentration of a solute is equal on both sides of a membrane?

The concentration of solute molecules on both sides of the membrane will vary over time, and the solute molecules will continue to pass through the membrane even when the concentration gradient is reversed.

The environment in and around the cell is constantly. The diagram shows a cell with a higher concentration of solute molecules on the inside than on the outside. This means that there is a concentration gradient, and the solute molecules will tend to move from the inside of the cell to the outside. This process is called diffusion.

The solute molecules can also move through the membrane by other mechanisms, such as facilitated diffusion and active transport. Facilitated diffusion is a process that uses proteins in the membrane to help the solute molecules move across the membrane. Active transport is a process that requires energy to move the solute molecules across the membrane.

The concentration of solute molecules on both sides of the membrane will continue to change over time. As the solute molecules move from the inside of the cell to the outside, the concentration of solute molecules on the inside of the cell will decrease. This will create a new concentration gradient, and the solute molecules will continue to move from the inside of the cell to the outside.
