A wave hits an object as shown
Which kind of wave interaction is shown?
absorption
Diffraction
Refraction
Reflection
Answers
Answer:
Refraction
Explanation:
The given type of wave interaction is diffraction. Thus, the correct option is B.
What is Diffraction?Diffraction is the phenomena of spreading of waves around the obstacle particles. Diffraction takes place with sound waves with electromagnetic radiations, such as light, X-rays, and gamma rays and with the very small moving particles such as atoms, neutrons, and electrons, which show wave-like properties.
Types of diffraction include:
1. Fresnel diffraction: This type of diffraction is caused by the light from a point source. In Fresnel diffraction, the incident and the diffracted wavelengths are spherical or cylindrical in nature.
2. Fraunhofer's diffraction: In this type of diffraction, The incident and the diffracted wave fronts are both plane type.
Therefore, the correct option is B.

Mitosis should be error free; however, if errors do occur healthy cells can become___
cells.
Answers
Answer:
Explanation:
When a cell divides, it creates two identical daughter cells that each carry a copy of the original cell's DNA. The name for this process is mitosis, and errors in the process result in incorrect DNA copies. The effects of these errors on the health of the organism range from benign to deadly, depending on their number errors and type. One potential consequence is cancer;
How would plant populations be affected if the populations of decomposers,
such as earthworms, decreased dramatically?
O A. Plant populations would flourish because they would no longer be
preyed upon by earthworms.
O B. Plant populations would suffer because the soil would have fewer
available nutrients.
O C. Plant populations would be unaffected by changes in the
earthworm population.
D. Plant populations would flourish because they would not need to
compete with the worms for nutrients.
pleaseee helppppp
Answers
Answer: B. plant population would suffer because the soil would have fewer available nutrients.
Explanation:
Earthworms are called a farmer's best friend as they make the soil more fertile. When earthworms purify the soil it makes it easier for the plants to grow as the soil is mineral rich. Decrease in the population of earthworms would make it difficult for the plants to grow because of the less fertile soil.

Given the choice of 4 bases and the number of bases needed to make up a codon, how many possible codons are there? 16 23 64 128
Answers
Answer:
64
Explanation:
A codon is a group of three nucleotide sequence in a mRNA that specifies a particular amino acid acid. There are only four nucleotides composed of the four nitrogenous bases viz: Adenine, Guanine, Cytosine and Thymine/Uracil.
A codon is composed of only three of these nucleotide bases at a time. Hence, considering the number of nucleotide bases that can make up one codon and the 4 nucleotide bases, there can only be 4^3 = 64 combinations of the four nucleotides. This means that there are 64 possible codons.

a. Two masses are moved further apart
b. Two masses are moved closer together
Answers
Answer:
a. When two masses are moved further apart from each other, the gravitational force between them will be weaker. They will not have a large effect on each other.
b. However, when two masses are moved closer together, the gravitational force between them will grow stronger (a prime example of this is the Sun's gravitational force on the Earth). The larger the mass is, the higher effect it will have on other bodies of mass.
Parents that are heterozygous for having freckles (dominant) are crossed.
What represents the ratio of their offspring? Draw a Punnett square and show your work.
Answers
Answer:
Phenotypic ratio - 3 Freckes : 1 No freckles
Explanation:
This question represents a monohybrid cross i.e. involving a single gene coding for possession or not of freckles. The allele for possession of freckles (F) is dominant over the allele for no freckles (f).
In a cross between two HETEROZYGOUS parents i.e. Ff × Ff, each parent will produce gametes with alleles F and f respectively. Using a punnet square (see attached image), four possible offsprings will be produced with genotypes: FF, Ff, Ff and ff.
Based on this genotypes, the phenotypic ratio of the offsprings will be 3:1 where 3 offsprings will possess freckles and 1 will have no freckles.

During an earthquake, what is the most destructive type of seismic wave that caused a rolling motion?
1. P waves
2. S waves
3. Surface waves
4. Transverse waves
Answers
Answer:
Surface Waves
Explanation:
Surface waves cause more damage because they produce more ground movement and travel slowly, which makes it take longer to pass.
During an earthquake, the most destructive type of seismic wave that caused a rolling motion is known as a Surface wave. Thus, the correct option for this question is C.
What is an Earthquake?An earthquake may be defined as a sudden trembling of the surface of the earth. It causes great destruction, as a result of movements within the earth's crust or volcanic action. The circumstance of an earthquake is fatal to living organisms.
According to the context of this question, surface waves are those waves that significantly cause more threats to the surface of the earth. they effectively construct more ground trembling and movement. These waves travel gradually and this makes it take longer to pass.
Therefore, during an earthquake, the most destructive type of seismic wave that caused a rolling motion is known as a Surface wave. Thus, the correct option for this question is C.

Plants get for photosynthesis from the sun.
Answers
Answer:
Plants gain food from the sun by Photosynthesis,
Explanation:
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct
Answer:
Light energy
Explanation:
Photosynthesis is a process that certain organisms called autotrophs, undergo to make their own food. Autotrophs are also called producers. Some examples of autotrophs/producers are plants and algae.
The photosynthesis equation is
carbon dioxide+water+light energy —> glucose+ oxygen
Carbon dioxide, water and light energy from the sun are turned into glucose (the food for the organism) and oxygen (waste product).
The sun provides the plant with light energy for photosynthesis. Therefore, the answer is light energy.
