An acellular entity made up of a small circular RNA molecule without a capsid and capable of replicating its genome is known as viroid.
What is RNA?RNA is a complex high-molecular weight molecule that participates in cellular protein production and, in some viruses, replaces DNA as a carrier of genetic instructions.
Viroids are nucleic acid species with a unique structure and low molecular weight that cause a variety of illnesses in cultivated plants. Certain animal and human diseases may be caused by similar nucleic acid species. Viroids are the tiniest known infectious disease agents.
Viroids, unlike viral nucleic acids, are not encapsulated. Viroids multiply autonomously in cells of sensitive plant species, despite their small size.

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.

The relative humidity of a dry-bulb temperature of 15°C and a wet-bulb temperature of 12°C is 71%.
What do you mean by Relative Humidity?Relative humidity may be defined as the proportion of atmospheric moisture present compared to the amount that would be present if the air were permeated.
Relative humidity can be calculated by subtracting the temperature of the dry bulb from the temperature of the wet bulb.
After getting a specific value, refer to the relative humidity chart at the particular value of the dry-bulb temperature.

PURPOSE: To measure response time after visual, auditory, and tactile stimuli have been practiced.
MATERIALS: meter stick or a yard stick (If you don’t have one - something about three feet long and stiff will work. You could get cardboard for example and mark off the distances on it..)
PROCEDURE:

Your LC, friend or family member will hold the meter stick in a vertical position so that the zero end of the meter stick is halfway between your thumb and forefinger. The holder of the stick will drop it without warning you. You are to catch the meter stick as soon as possible after it has been released. Record on the data table the number of centimeters the meter stick dropped before you caught it.
Repeat the procedure 9 more times.
Repeat the procedure in steps 2 and 3 but this time close your eyes and have your LC, friend or family member tell you the moment the meter stick is dropped. Repeat this 9 more times and record the data in the data table.
Repeat the procedure in steps 2 and 3 but this time use a tactile stimulus. Have your LC, friend or family member touch you as soon as the meter stick is dropped. Be sure your eyes are closed. Repeat 9 more times and record your data.

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.

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.
