the diagram shows the movement of water through a plant which two terms or phrases describe the process shown
azamat

Answer:

B. Open Stomata

C. Transpiration

Explanation:

Even though plants take up a lot of water from their roots, they lose about 95% of it to the atmosphere in the process known as Transpiration.

Transpiration is done for several reasons: it cools the plant down, it enables plants to access the nutrients in the water as the water moves along the plant and it enables gaseous exchange.

The gaseous exchange happens because carbon dioxide comes in from the same holes on the leaf that the water leaves through to the atmosphere, the open stomata.

kompoz [17]

Answer:

b- It is a spontaneous process.

Explanation:

Passive transport is the type of transport of substances across the plasma membrane that occurs without energy expenditure and occurs spontaneously.

Substance transport occurs until concentrations inside and outside the cell are equalized.

According to this conceptualization we can conclude that the correct answer to your question is the letter B.

Which of the following is a way that new DNA can be introduced to bacteria?
OLEGan [10]

Answer:

B

Explanation:

<em>The correct answer here would be that </em><em>it can be injected by a virus.</em>

Since a virus operates by taking over the genetic system of the host and uses its replication, transcription, and translation to make virions or viral particles through the lytic or lysogenic life cycle. In the process, if the virus is utilized as a vector to carry a foreign DNA, the DNA is introduced into the genome of the bacteria. This is exactly what happens during the process known as transduction.

<em>The correct option is, therefore, </em><em>B.</em>
