The correct answers are as follows:
1. In a plant stem, the vascular tissue is CONTINUOUS FROM THE ROOTS TO THE LEAVES.
In plants, vascular tissues refers to a conducting tissue, which is found in most vascular plants. The conducting tissue is made up primarily of xylem and phloem, which transport water and nutrients to all parts of the plant's body. The continuation of the vascular tissues from the root to the leaves allow them to transport the needed materials to all parts of the plants.
2. The function of the leave that is taken up by the stem of such cacti is PHOTOSYNTHESIS.
Cacti is a kind of plant that is found in hot and dry climates, because of this, the plant has to adopt some adaptations, which reduces the amount of water that is lost from its body. One of this adaptations is the absence of leaves, through which water can easily evaporate. Because cacti lack leaves, they utilize their stem instead in the process of photosynthesis.
Answer:
Scientist are making efforts from a very long timem to establish life outof the Earth and once they selected moon for that.
For human survival water and oxygen are two essential components. Scientsts from NASA have launched many programms to such as Apollo to land human on Moon surface, which was successful. Other programs were also run by NASA to make humans live and work their but it was important to find out the existence of water first to live in Moon. LRO satellite found the existence of water (lunar water) on the Moon surface but because of less funds and delayed in the program, the mission was dropped.
But according to me, humans should establish an outpost on the Moon as water resources already exist in the Moon and water regulates most of the process in human body. Oxygen is already 40percent by mass at lunar crust which can be extracted as scietist says. so, This will maiantain the environmetal condition on the Earth as well, if the population will shiftto Moon.

OO, then offspring will be AO or BO in 50:50 percentages. </span>
Answer:
I believe it is b
Explanation:
I may be incorrect but genetics and natural selection are my passion so I believe this is correct. The way genes work is you receive half of your father's genes and half of your mothers. Whichever genes are dominant end up showing up on your body, which is called a phenotype. DNA is what makes up genes and makes them able to affect you. Let me know if I'm incorrect.
Answer:
Replace the concentration descriptions with actual values.
Explanation:
A graph is used to convey real, accurate and objective information. The use of the description of the concentrations in place of the real values, does not represent an accurate information, but a subjective and imprecise information. For this reason, to improve the quality of this graph and allow the readers to fully understand it, it would be necessary to replace the descriptions of concentration with real values.
