Answer:
The types of point mutation depicted are:
1. C. Silent mutation
2. B. Nonsense mutation
Explanation:
Point mutation is known to be a mutation that actually affects a single nucleotide and it has to do with the substitution of one base for another. This substitution can occur by changing, inserting or deleting a DNA or RNA sequence. A nonsense mutation refers to a change in DNA which leads a protein to either terminate or end its translation so quickly than expected. This mutation is commonly seen in humans.
Silent mutation is known to be the mutation in DNA whereby there are no effects which are observable in an organism's phenotype. This type of mutation are seen as a specific type of neutral mutation.

The Wunderlich Farms Boer Goat has a 4 chambered stomach and chews it's cud to assist with digestion. What type of adaptions are these?
A. 4 chamber stomach = behavioral and chewing cud = internal structural
B. 4 chamber stomach = external structural and chewing cud = behavioral
C. 4 chamber stomach = internal structural and chewing cud = external structural
D. 4 chamber stomach = internal structural and chewing cud = behavioral
Answers
Answer:
The answer is option A "4 chamber stomach = behavioral and chewing cud = internal structural"
Explanation:
Goats and other ruminants do not digest food directly as they eat their food and the reason is that ruminants do not have the enzymes that are necessary for breaking down the food directly as they eat so digestion in ruminants and particularly Goats has to undergo processes or procedures before the final digestion takes place.
All the processes in digestion for ruminant animals takes place in their four chambered stomachs which are the Rumen, Reticulum, Omasum and Abomassum.
In the four chambered stomach of Goat, the type of adaptation is behavioral and chewing cud which is the internal structure.

Answer: Attenuation
Explanation: Natural attenuation: in this method, the natural physical, chemical, and biological processes in soil and water gradually break down contamination or pollutants into harmless components. It helps reduce contamination concentration and soil and water to acceptable levels. Examples of natural attenuation processes include
- dilution or dispersal of pollutants in moving water
- volatilization or reduction of pollutants into vapor
- absorption or attachment of balloons to soil or vegetation
These processes are accomplish naturally. Little or no human intervention is necessary.

In the natural attenuation method, the natural physical, chemical, and biological processes in soil and water gradually break down pollutants.
Explanation:
In a certain plant, the allele for red flower color (R) is dominant over the allele for white flower color (r). A cross is performed between a plant with red flowers and a plant with white flowers. The offspring are 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants?
Answers
Answer:
Rr and rr
Explanation:
The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).
Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr).
Rr x rr
Rr Rr rr rr
Rr = red
rr = white
If the red parents is true-breeding
RR x rr
Rr Rr Rr Rr
All their offspring would be red without any white flower color.
Hence, the genotypes of the parent are Rr and rr.

is biological control effective than chemical control of crop protection?
Answers
Answer:
No
Explanation:
There are different ways or methods of protecting crops from pest and disease infestation. Two of those ways as mentioned in this question are the chemical control and biological control. Biological control of crop protection involves the use of natural enemies of crop pests, which happens to be living or biotic organisms while chemical control entails the use of pesticides and herbicides to control crop pests and diseases.
Among these two methods, the chemical control is more effective because it yields instantaneous results and gets rid of pests and diseases faster. However, in terms of sustainability, the biological control method is more eco-friendly. Hence, based on this question, biological is not more effective than chemical control of crop protection.

Answers
crossing over is when the alleles cross over and pair up, resulting in the genotype for an offspring
Crossing over is when the alleles cross over and pair up, resulting in the genotype for an offspring.
What is Crossing over?When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the formation of egg and sperm cells (meiosis).
This mechanism leads to novel allele combinations in the gametes (egg or sperm) generated, ensuring genetic variety in any baby born.
Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes — one from the mother and one from the father — line up, parts of the chromosome can be switched.
Therefore, Crossing over is when the alleles cross over and pair up, resulting in the genotype for an offspring.

Two multi-celled organisms uses meiosis and fertilization to create a unique offspring.
Two multi-celled organisms use mitosis and fertilization to create a unique offspring.
A single-celled organism uses mitosis to create two identical copies of itself.
Answers
The statement “ A single-celled organism uses mitosis to create two identical copies of itself” best describes asexual reproduction
The statement which best describes the mode of asexual reproduction is that a single-celled organism uses mitosis to create two identical copies of itself. Thus, the correct option for this question is D.
What is Asexual reproduction?Asexual reproduction may be characterized as a mode of reproduction in which a new offspring is produced by a single parent. This type of reproduction does not involve the fusion of gametes or a change in the number of chromosomes.
Asexual reproduction is homologous to the process of mitosis. This is because both of them involve the production of two identical daughter cells from a parental cell.
While meiosis produces four daughter cells which are genetically unique to the parent cells. It is the characteristic feature of sexual reproduction that is opposite to an asexual one.
Therefore, the correct option for this question is D.

What is the element or compound in the Phosphorus Cycle and why is it important to living things?
Answers
Answer:
Phosphorus is an essential nutrient for animals and plants. It plays a critical role in cell development and is a key component of molecules that store energy, such as ATP (adenosine triphosphate), DNA and lipids (fats and oils). Insufficient phosphorus in the soil can result in a decreased crop yield.
Explanation:
Answer:
Thus, phosphorous is crucial to living organisms because ATP is crucial. Phosphorus is also important because it makes up our DNA. Phosphate is part of the so-called ladder legs which Adenine, Thymine, Guanine, and Cytosine bind to see. It holds this same job in RNA.

What is ATP?ATP, sometimes referred to as adenosine triphosphate, is a chemical that transports energy inside of cells. It is produced as a byproduct of photophosphorylation, which adds a phosphate group to a molecule using light energy, cellular respiration, and fermentation. It serves as the primary energy currency of the cell.
All forms of life utilize ATP. In addition to being used as an energy source, it is also integrated into deoxyribonucleic acid (DNA) during DNA synthesis and utilized in signal transduction pathways for cell communication.

Answer:
Vibration of individual particle will increase
Explanation:
This is due to the fact that whenever any substance of matter is increased in temperature, the atoms begins to move away from each other. Take for instance an ice cube for example, when an ice cube (a solid) is heated it becomes water, (a liquid). Proving that when a substance is heated, no matter the density of the material, the individual particles, or atoms, begins to spread apart.
