Answer:
D. A hormonal signaling pathway between endocrine glands and tissues
Explanation:
Our body is formed by a complex organization of various tissue, organs and organ-systems. It has specific mechanisms to regulate the functions of all its cell, tissue and organs. Besides neural system, the endocrine system also plays a crucial role in the regulation of body functions. This system consists of many pathways that originate from the hormone secreting glands called endocrine glands and reaches to the target cell or tissue or organ. These pathways are collectively named as the endocrine axis.
Answer:

Answer:
12 : 3 : 1
white : yellow : green
Explanation:
Given that genes A and B control the fruit colour in following ways:
A_B_ or A_bb = white
aaB_ = yellow
aabb = green
The genes undergo independent assortment so:
AaBb X AaBb =
A_B_ : A_bb : aaB_ : aabb
9 : 3 : 3 : 1
white : white : yellow: green
12 : 3 : 1
Hence, ratio of white : yellow : green is 12: 3: 1
Water cycles through organisms and rivers.
1. Evaporation is the escape of water molecules from their liquid phase to gas phase that go up into the atmosphere. Evaporation can occur anywhere where open liquid water is exposed to sunlight or any other source of energy. Transpiration, on the other hand, is the loss of water (by evaporation) from plants through the stomata. Evaporation and transpiration move water from the biosphere to the atmosphere.
2. Condensation is the return of water molecules from gaseous phase (vapor) back to liquid form. Precipitation, on the other hand, is the coming down of condensed water from the atmosphere to the earth (biosphere), which is a significant part of the water cycle.
3. Exchange pool is the pool from (or approximate amount) which water or other elements are shared (back and forth) between different spheres (such as biosphere, atmosphere, and hydrosphere) in a cycle. A reservoir on the other hand is analogous to a ‘container’ that holds large masses of water or other elements such as a lake and the atmosphere.
4. The answer is No. because, today’s waters, due to increased pollution from industrialization that spews a lot of pullutans into the atmphere, ae contamiated. The water that precipitates is tainted by gases such as sulphuric dioxide tha makes it acidic. The water also gets polluted by other pollutants in the atmpshre and biosphere and hence become a health risk to animals and humans that drink it.
