There is a species of frog on an island that puzzles scientists. The proportion of frogs with no stripes is greater than the proportion of frogs with stripes. This is puzzling because the unstriped trait is recessive (s), and the striped patterns are due to dominant alleles (S). Also, natural selection seems to support the striped trait.
How do genetic factors most likely account for the proportion of traits in the frog population?
A. Most of the striped frogs and unstriped frogs have the genotype ss.
B. Most of the striped frogs have the genotype SS and the unstriped frogs have the genotype ss.
C. Most of the striped frogs have the genotype SS and the unstriped frogs have the genotype Ss.
D. Most of the striped frogs have the genotype Ss and the unstriped frogs have the genotype ss.

What are the similarities between dna and rna molecules? (4 points)
a double stranded helix, a phosphate group, and a hexose sugar
a nitrogenous base, a phosphate group, and a pentose sugar
a nitrogenous base, an amino acid, and a pentose sugar
a single stranded helix, a phosphate group, and a pentose sugar
Answer:
a nitrogenous base, an amino acid, and a pentose sugar
DNA and RNA molecules share several similarities in their structures. Both consist of a nitrogenous base, a phosphate group, and a pentose sugar. However, they differ in their helical structure, with DNA typically being double-stranded and RNA single-stranded. Thus, correct option is (B).
Ribonucleic acid and deoxyribonucleic acid are two chemicals that are crucial for genetics and other biological processes. Both of them contain pentose sugars, phosphate groups, and nitrogenous bases. Adenine (A), cytosine (C), and guanine (G) are the nitrogenous bases in both DNA and RNA; thymine (T) and uracil (U) are also present in both.
Although they both include a phosphate group and a pentose sugar (deoxyribose in DNA and ribose in RNA), the structural configurations of DNA and RNA are different. The two strands of DNA are typically kept together by base pairing to create a double helix. The majority of RNA, on the other hand, is single-stranded. Their functions and cellular processes are different as a result of this structural heterogeneity.

2. what is the trend between 20-30 years in the kelp population? explain.
The trend between 20-30 years in the kelp population is that it is reducing due to sea urchins eating kelp and clipping the bottoms, hence, stopping kelp from regrowing.
What is the trend in the Kelp population?Kelp is a form of giant seaweed found in ocean floors.
Kelp serve as food for certain sea animals such as sea urchins.
However, due to increasing number of sea urchins and increase in environmental pressures, the Kelp population reduced in the last 20 to 30 years.
Therefore, the trend between 20-30 years in the kelp population is that it is going down due to sea urchins eating kelp and clipping the bottoms, hence, stopping kelp from regrowing.

1. A 42,000 kg train car travelling at 10 m/s toward a stationary train car with a mass of 40,000 kg. After collision, the two sticked and moved together with the same speed. Solve for the final speed of the combined object after collision and identify their direction.
Given,
A 42,000 kg train car travelling at 10 m/s toward a stationary train car with a mass of 40,000 kg.
What is momentum?Momentum is a product of the mass of a particle and its velocity. Momentum is a vector quantity which means it has both magnitude and direction. Its formula = mass × velocity.
Solve for momentum:
M= (42,000kg)(40,000kg) / (10m/s)
M = 42,000 kilograms - 40,000 kilograms
M = 2,000kg
M = 2,000 kg ÷ 10m/s
= 200m/s
-Thus they collison at the same speed of 200m/s.
