Answer:
Environmental impacts of particles, such as dust and smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem
Environmental impacts of greenhouse gases released from livestock production - increase in atmospheric temperature
Explanation:
Environmental impacts of particles, such as dust and smoke, released from livestock production -
Release of particles such as dust and smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs.
These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc.
Environmental impacts of greenhouse gases released from livestock production -
Green house gases will lead to increase in atmospheric temperature
The Iron in the molecule binds to the oxygen. Carbon Dioxide does not bind to a cell but rather, is carried in the blood as bicarbonate.
Answer:
Option C
Explanation:
Long term hunting has led to following
a) Reduction in population size and hence the gene pool
b) Causation of Bottleneck effect
Due to above factors, the remaining population of Northern elephant seals does not represent the original genetic problem.
Due to this restriction in mating and genetic variation shall prevail pertaining to reduced gene pool.
Due to continuous hunting, the gene pool will further shrink, leading to genetic similarity among the organism
Option C is correct
Answer: elastic fibers
Explanation:
Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary, cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.
Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.
Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.
It is false that cytoplasm is a single substance like water.
It consists of 80% water, but has other elements as well.
