B) Protein passed from the heat-killed strain to the living strain.
C) The phosphorescence in the living strain is especially bright.

Answer:

A) DNA passed from the heat-killed strain to the living strain.

Explanation:

This is an analogue to the Griffith´s experiment, reported in 1928. He tested Streptococcus pneumoniae transformation, which changed from non virulent to virulent. That was the first experimental evidence of bacterial transformation, this is, the transference of genetic material from one bacteria to another.

Answer:

Knee.

Explanation:

Joints may be defined as the articulation by which the bones meet together and constitute the skeletal system. These joints helps in the particular movement of the body.

Answer:

1) abiotic synthesis of small organic molecules (monomers)

2) joining of monomers into polymers

3) packaging of these molecules into protobionts, droplets with membranes that maintained a distinct internal chemistry

The movement of nutrients into the vascular stele sometimes requires energy from:
Vlad1618 [11]
The movement of nutrients into the vascular stele requires energy, unlike the movement of water that does not require energy. This energy is provided by the phloem. Sugars are produced in the leafs, as part of the photosynthesis process, so whenever a new root is growing, or a fruit needs to grow, the phloem gets in action. With the help of the water the sugars get in the phloem, which can most simply be seen as an elevator inside the plant, that is moving nutrients up and down, on the places in which they are most needed.

why does the presence of 22 large herbivore species at Mpala seem to contradict the competitive exclusion principle Dr. Pringle
stealth61 [152]

Dr. Pringle suggests that there's only very few large herbivorous species that can survive in certain area. The reason behind his claim is that according to him there will be only enough food for few large species, so there's natural limitations in the food sources, as there should be enough to support them in order for them to survive.

On the other hand, in Mpala, there's 22 large herbivorous species, which directly contradicts Dr. Pringle's hypothesis. The reason why so many large species of herbivores an survive in Mpala and always have enough food for all of them, is that they have all specialized in eating certain types of plants or parts of plants, thus they are not direct competition to one another, and there's always enough food for all of them.

<span>Connective tissue supports the framework of the liver, and epithelial tissue protects the liver. Connective tissue holds the liver in place during movement, and epithelial tissue forms the lining of the liver. Connective tissues are mainly used in forming support networks within tissues and Epithelial tissue tend to line the organs and form protective cell layers.</span>
