Answer:
Earth radiates infrared radiation.
Incident infrared radiation is blocked.
Infrared radiation is blocked and heats Earth.
Visible and ultraviolet radiation heat Earth.
Explanation:
When the sunlight enters earth's atmosphere, it has short wavelength but after hitting the earth surface, it has long wavelength which allow very less solar radiation by the clouds and greenhouse gases to go into the atmosphere and as a result the earth heat up. if the greenhouse gases are increased in the atmosphere so more heat is blocked by these greenhouse gases and as a result global warming occur.
Answer:
The correct answer is - stem cells.
Explanation:
Stem cells can give rise to all tissues and organs in the body. These cells can differentiate into any form of cells, which allows them to repair tissues that have been damaged by various physiological or natural ways
There are two types of stem cells: Adult Stem Cells and Embryonic stem cells.
Cells that are present in the bone marrow or umbilical cord of a newborn baby and can be divided as Hematopoietic, a cell that can form blood cells and the immune system, and mesenchymal that form the body's cartilage, bones, muscles and other.
Embryonic stem cells are found on at blastocyst stage of embryo. These cells can transform into any type of tissue in the human body, which increases their treatment potential.
Options are:
a) lymph.
b) interstitial fluid.
c) extracellular fluid (ECF).
<span>d) plasma.
</span>
All the following are correct terms for this fluid except lymph.
The interstitial fluid surrounds the cells in the body. The other major component of the ECF is the intravascular fluid of the circulatory system called blood plasma<span>.
</span>Lymph is<span> a fluid which contains infection-fighting white blood cells, throughout the body.</span>
Green in color due to the chlorophyll used to absorb energy from the sun.<span />
Vascular tissue<span> is a complex conducting </span>tissue<span>, formed of more than one cell type, found in </span>vascular plants<span>. The primary components of </span>vascular tissue<span> are the xylem and phloem.</span>
