Answer: Autonomic Nervous System
Explanation: Automatic nervous system is a system that controls system that unconsciously regulate
Bodily functions such as digestion,urination,heart rate,sexual arousal,respiratory rate,pupillary response
Blood and lymph are the two circulating fluids in the animal body. Blood belongs to the circulation system whereas lymph belongs to the lymphatic system. Blood contains pigments which carry oxygen. Therefore, blood can be found in different colors in different types of organisms. But, lymph is a colorless fluid. Blood is composed of red blood cells, white blood cells, platelets and a fluid called plasma. Lymph is composed of white blood cells and a watery fluid. Both blood and lymph possess a circulatory function as well as an immune function. The main difference between blood and plasma is that blood circulates inside blood vessels whereas lymph circulates inside lymphatic vessels.
Answer:
c) active
Explanation:
When in an atom the outermost shell is not full (eg. 2,8,3 ; here in the last shell it is not filled completely and needs 5 more electrons to complete it ) then the atom becomes active and molecules doesn't react unless and until an atom is active .

Answer:
The flowering population is in Hardy Weinberg equilibrium.
Step by Step Explanation:
Total initial population size = 60
As both the populations are homozygous so the frequency of alleles will be,
P = 80/120= 0.66
q = 40/120= 0.33
The predicted frequencies for genotypes once the population has reached Hardy-Weinberg
p2 = 0.4356
2pq= 0.4356
q2 = 0.1089
The number of plants with each type of flower in a papulation of 420 is,
Homozygous dominant= 185
heterozygous= 185
Homozygous recessive= 50
Chi square analysis:
The observed values for red-flowered plants, pink-flowered plants, and white-flowered plants are not significantly different from the expected values predicted by Hardy Weinberg equilibrium.
Phenotype observed(o) expected (e) (o-e)2/e
Red 178 185 0.26
Pink 190 185 0.135
White 52 50 0.08
chi-square = 0.474
With 2 degree of freedom this chi-square gives a p value of 0.7 - 0.8, which is not significant.
Answer:
About 61% / over 60%
Explanation:
In 2021, about 4,116 billion kilowatthours (kWh) (or about 4.12 trillion kWh) of electricity were generated at utility-scale electricity generation facilities in the United States.1 About 61% of this electricity generation was from fossil fuels—coal, natural gas, petroleum, and other gases.
