Answer:
probability of the child having attached earlobes since it is recessive i.e (yy)
=1/4
=0.25 × 100%
=25%
Explanation:
If two heterozygous individuals have a child
i.e let the heterozygous individuals be = Xy
if both traits crosses together; their F₁ offspring will be; (XX, Xy, Xy, yy)
Xy × Xy
X y
X XX Xy
y Xy yy
probability of the child having attached earlobes since it is recessive i.e (yy)
=1/4
=0.25 × 100%
=25%
Answer:
Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl.

Answer:
Daphnia is an ideal system for studying multiple stressors because of its short generation time, well-studied ecology and evolutionary history, wide geographical distribution across many limnetic systems, high mutation and recombination rates, high sensitivity to changes in environmental conditions, unique cyclical
Explanation:
They are paired, placed in launae and have canaliculi to receive and send nutritive materials to matrix.
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
