Answer:
Cyanide may cause muscle weakness because tissues are not able to use oxygen for cellular respiration
Explanation:
Cyanide is a highly toxic compound that inhibits cellular respiration by inactivating cytochrome oxidase in mitochondria, which is a key enzyme responsible for oxidative metabolism and energy production. Thus, cyanide consumption decreases the utilization of oxygen by muscle cells, thereby causing weakness. The symptoms of cyanide poisoning include, among others, weakness, malaise, visual disturbances, muscle pains, etc.
Answer:
Each daughter cells will have 18 chromosomes. The diploid cells yields two diploid daughter cells after division.
So I believe the answer would be 2.
Explanation:
After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.
Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.
Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:
- Algal bloom: the nutrients facilitate the rapid growth of algae
- The bloom of algal species results in the death of underwater plants as a result of inadequate light.
- The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.
- Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxia
Therefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

Answer:
Metaphase
In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
Using two heterozygous tall pea plants, so Tt is the genotype.
T t <---- alleles from parent one
T TT Tt
t Tt tt
^alleles from parent two on the left
Results: TT, Tt, Tt, and tt
Genotype ratio: 1/4 TT, 1/2 Tt, 1/4 tt
Phenotype ratio: T is dominant over t, so 3/4 tall and 1/4 short pea plants
