Excess nitrogen can also leach or drain from the soil into underground water sources, or it can enter aquatic systems as above ground runoff. This excess nitrogen can build up, leading to a process called eutrophication.
Answer:
Option A
Explanation:
Given -
Man has X-linked recessive trait . Thus its genotype can be represented as
YX'
Woman has normal vision with homozygous genotype i.e "XX"
A cross is carried out between the above two parents thereby producing following offspring -
Y X’
X XY XX’
X XY XX’
Out of four offspring two are boy "XY" which do not have Red-Green Color blindness
While the two daughters "XX' " have Red-Green Color blindness
Thus, all the daughters produced have Red-Green Color blindness. Thus the chance of having a daughter with color blindness is 100 percent
Option A
Answer:
1. primary cause of human-created carbon emissions = burning fossil fuels
2. destroys natural carbon sinks leading to more carbon dioxide in the air = deforestation
3. emits methane from decomposing matter = waste disposal in landfills
Explanation:
1. "Fossil fuels" are <em>nonrenewable resources</em> that are considered essential for the operation of many factories and industries. <em>Burning them accounts for most of the carbon emissions on Earth</em>, and this leads to<em> "global warming."</em>
2. "Forests" are considered "carbon sinks" because they have a role of <u><em>absorbing the carbon dioxide in the atmosphere</em></u>. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.
3.<em> Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere.</em> Methane is considered a <em><u>potent greenhouse gas</u></em> that affects people's health.

Tissues refer to a group of similar cells that perform a particular function. In vertebrates, the tissues are orgainzed into four types called the epithelial tissues, muscle tissue, connective tissue and the nervous tissue.
Epithelial tissue refers to the tightly packed group of cells covering the body outside, lining the body cavities and glands. Based on the shape, it is classified into squamous (flat), cuboidal and columnar. It can be single layered (simple) or stratified (multilayered). It protects the body, helps in the absorption of nutrients and elimination of wastes.
Muscle tissue is made up of the muscle cells that coordinate and bring movement and locomotion. It is made up of muscle fibres and the proteins called the actin and myosin. Muscle tissue is of three types-
(a) Skeletal muscle tissue is a striated tissue which is under the voluntary control.
(b) Smooth muscle tissue found in the walls of the blood vessels, digestive tracts and other parts of the body and are involuntary in nature.
(c) Cardiac tissue is an involuntary, straited tissue found in the walls of the heart.
Connective tissue contain cells present in an extracellular matrix connecting tissues, giving shape to the organs and holding them in place. It can be classified into loose connective tissue found throughout the body, dense connective tissue found in the bones and the ligaments and fluid connective tissue of the blood.
Nevous tissue is the tissue involved in control and coordination of the body. It helps in transmission of messages in the form of nerve impulse with the help of the structural and functional unit of the nervous system called the neurons.
