Answer:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair 3/4
ss 1/4 Long hair 1/4
Explanation:
The resulting off-spring would have the following genotype and phenotype:
1 out of 4 will have a genotype of SS.
2 out of 4 or half will have a genotype of Ss.
1 out of 4 will have a genotype of ss.
But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:
Short hair: 1/4 + 2/4 = 3/4
Long hair: 1/4
Answer:
Linnaeus primarily used physical characteristics.
Explanation:
Convergent evolution explains that non-related species can develop similar traits due to adaptations that happened while living in similar ecosystems. For example sharks which are a type of fish have similar body plans to dolphins, a type of mammal.
5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.
<h3>Given</h3>
Mass of oxygen at room temperature =500.0 ml
Volume of pressure = 50 atm pressure.
The gas to a volume = 150.0 ml
<h3>Explanation</h3>
The volume decreases by the factor = 500.0 mL / 150.0 mL
= 10 / 3
The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to
= 5.00 atm
So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

Answer: Since nutrients are needed to build life tissues and carry out essential life functions, a limiting nutrient (scarce nutrient) will limit organisms' growth in an ecosystem.
Diatoms contain chloroplasts that have four membranes. These four membranes are evidence of secondary endosymbiosis (Option c).
<h3>What is secondary endosymbiosis?</h3>
Secondary endosymbiosis is a hypothesis used to explain why diatom chloroplasts have four membranes.
According to this hypothesis, diatoms received different genes from distinct photosynthetic and non-photosynthetic ancestors.
The acquisition of genes of different ancestors led to diatoms having chloroplasts with four membranes.
