Answer:
Regions of ER that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth ER.
Answer;
He conducted an experiment with breeding pigeons.
Explanation;
The pigeons provided the perfect animal to test his theory of selection for quite a number of reasons including its trait diversity from wing structures to color patterns to size to flight patterns. From these experiments he concluded that by natural selection of randomly occurring traits that make species better suited for survival and reproduction, evolve in the astounding diversity of organisms on Earth today.
A lot of carbon stored inside the Earth may soon re-enter the atmosphere, according to a new, global study on soil-based carbon. The massive release of carbon could be the equivalent of adding another fully industrialized country the size of the United States to the map over the coming decades.
Plants, animals, and microbes absorb much of the carbon dioxide released into the Earth's atmosphere by burning fossil fuels. As these plants and animals die, their carbon-based bodies become part of the soil, storing the equivalent of millions of tons of greenhouse gases in the dirt. As atmospheric carbon dioxide is a primary driver of climate change, some have pointed to this soil absorption as a helpful carbon sink, somewhat alleviating the human-caused warming of the planet. But as surface temperatures continue to rise, a lot of the carbon stored in the soil may be set to re-enter the atmosphere in a big way.
.B) decomposition of organic matter
Answer:
utilize a two-neuron chain to reach their effectors
Explanation:
Answer:
carrier protein
Explanation:
To resolve this, a specialized carrier protein called the glucose transporter will transfer glucose molecules into the cell to facilitate its inward diffusion. There are many other solutes that must undergo facilitated diffusion to move into a cell, such as amino acids, or to move out of a cell, such as wastes.
