Answer:  The correct answer is :  The state of the DNA that is transferred from one organism to another is Naked DNA.

Griffith's experiment went like this:

* Rough strain

* do not cap

Smooth strain

* capsule

* virulent (pathogenic) avirulent

Through DNA-mediated transformation, bacteria enter the DNA

Smooth strain (capsule) -> killed the mouse

Rough strain (no capsule) -> no effect on mouse

Heat killed smooth strain -> no effect on mouse

Heat killed smooth strain + living rough strain mixed -> killed the mouse

Water is able to travel against gravity, from the roots of a plant to the leaves at the top of the plant.
Juliette [100K]

Answer:

<em>The correct option is B) Capillary action, when adhesive forces are stronger than cohesive forces.</em>

Explanation:

When water leaves from the leaves of a plant through events such as transcription, a gap is produced in the capillary action of the xylem tube. As a result, more water is drawn from the roots to fill the void. The forces of attraction between the water and the xylem tube are much greater than the intramolecular forces of water. As a result, the water flows in an upward direction due to these string adhesive forces present between the water and xylem tube.

In what zone is the ability to burrow and sustain changes in temperature and salinity important for an organisms' survival?
den301095 [7]
The correct option is C.
Living organisms that live in the littoral zones in the ocean are used to frequent changes in temperature and in the salinity of the ocean water. For an organism to survive in this environment, it needs to have adaptive features that will increase its survival. The littoral zone is divided into three zones, which are high, middle and lower littoral zones. Organisms living in high littoral zone have adaptive features that make them more adapted to desiccation due to the long hours of sunlight to which they are exposed. The organisms are usually exposed directly to the air or they can be enclosed in burrows.

Lucille was finding it difficult to play soccer after school. Her doctor tested her cells and found that they contained low leve
Mashutka [201]

Answer:

The Lucille’s cells need Oxygen and glucose in order to function her body properly.

Explanation:

Our body breakdown the glucose using oxygen in order to produce energy.

By respiratory system we inhale oxygen and

By digestive system we digest food into glucose.

Our circulatory system transfer the Glucose and Oxygen to the all cells of our body,

Hence we can conclude that the Lucille’s cells need Oxygen and glucose in order to function her body properly.

boyakko [2]

Answer:

The correct option is A

Explanation:

To determine if water temperature has an effect on weathering of sedimentary rocks, different number (perhaps three) of identical sedimentary rocks should be obtained and then individually placed in different water temperatures (with at least one of the "water volumes" used for each having a temperature close to the room temperature so as to be used as the control).

Thus, each of the identical sedimentary rock can be broken into three and placed individually; as in one part of the rock in 20 °C of water (control), another part of the rock in 40 °C and another in 60 °C of water.

This above procedure should be repeated for the remaining two other identical sedimentary rock to confirm if there is any effect.
