The connective tissue is a type of the animal tissue which is developed from the mesoderm. This tissue is present between the other tissues. The composition of the different ground tissues vary based on the amount of fibers and ground tissue present in it. The connective tissue which is high in collagen fibers will be the strongest and toughest.
Hence, the answer is 'connective tissue high in collagen fibers'.
Answer:
protected; increase
Explanation:
Ozone is composed of trioxygen which is highly reactive gas compared to dioxygen. Ozone layer is present in stratosphere and troposphere and protect the humans from ultraviolet radiations but it may be toxic if inhaled. Ozone can be broken down into molecular oxygen by chlorine and bromine atoms.
A hole was discovered in ozone layer in 1982 and scientist believed that it could be dangerous for human health. The compounds involved in depletion of ozone are mainly Chlorofluorocarbons (CFS) and (HFCS). Then a global agreement was signed in 1987 which leads to prohibition of use of all chemicals that are involved in depletion of ozone layer. The problem of ozone depletion is solved by the agreement and ozone hole started to recover it from 2000.
But recent reports showed that the alternative chemicals used to protect the depletion of ozone layer began to trap the heat inside the earth like greenhouse effect. Now scientists are in search of chemical that can prevent both ozone depletion as well as global warming.
The wind makes pollination possible for gymnosperms. In gymnosperms ovaries are absent and the gametophytes of these plants are present on cones rather than flowers. Unlike angiosperms that get pollinated with animal interference, wind plays a crucial role in gymnosperm pollination.
Answer:
Explanation:
ells need both chloroplasts and mitochondria to undergo both photosynthesis AND cell respiration. After photosynthesis, which chloroplasts are needed for, which yields oxygen and glucose, plants need to break down the glucose and they use cell respiration to do this, which happens in the mitochondria.
