Answer:
The mutation that involves the change in the sequence of DNA bases is reflected both in the transcription of mRNA and in translation, giving rise to an alteration in the protein, which may not function and whose impact on the organism is a morphological or functional alteration.
Explanation:
According to this scenario, the DNA has experienced a mutation by changing the sequence by one of its bases, Cytosine by Thymine, producing in the mRNA a termination codon that interrupts the normal synthesis of the protein, preventing that protein from fulfilling its function. This particular mutation is called Nonsense mutation.
For normal DNA
DNA TAC CTC ACC GAG CGT
mRNA AUG GAG UGG CUC GCA
Protein Met - Glu - Trp - Leu - Ala
For the mutated DNA
DNA TAC CTC ACT GAG CGT
mRNA AUG GAG UGA CUC GCA
Protein Met - Glu - STOP - Leu - Ala
The change of a cytosine by Thymine in the mutated DNA produces that the third codon of the mRNA is altered, encoding a UGA termination codon, which prematurely stops the protein synthesis and originates an incomplete protein, probably not functional, whose impact in the organism is a morphological or functional alteration.

Answer:
In the population of the study, mutation in the achondroplasia gene is unusually high
Explanation:
In this population, the incidence of genetic mutation that leads to achondroplasia would be 6 children for every 30,000 births. In the general population, achodroplasia has an incidence of 1 per 30,000 births, which indicates that in this specific population, the mutation rate is high above average, which can be explained by a high prevalence of the gene in the population.
Achondroplasia is a genetic disease with inheritance of an autosomal dominant pattern and to suffer from the disease, only one copy of the defective gene is necessary.However, in recent years after several studies it has been possible to demonstrate that even achondroplasia could be generated even in new mutations in the germ cells of the parents.

Answer:
Patchy forest.
Explanation:
The patchy forest hypothesis is the second hypothesis that helps to explain the origin of the hominids. The hypothesis was developed by Peter Rodman and Henry McHenry.
This hypothesis suggest that the evolution of bipedalism is energy efficient in the environment that contain few tress. The patchy forest result in the dispersion of the forest and this might result in the energy efficiency of bipedalism by walking upright and collect their food with hands.
Thus, the correct answer is patchy forest.
It produces genetically identical cells.
0 It provides a means of asexual reproduction.

Meiosis is the process of cell division in which a single cell divides into four daughter cells. The genetic constitution of the daughter cells reduces to the half as compared with the parent cells. While crossing over, an exchanging of genetic material is passed between chromosomes and that allow variations to happen.

Answer:
The answer is Fixed Action Patterns
Explanation:
Fixed Action Patterns are fixed behaviors in certain animals which they carry out in response to stimulus. This patterns are constantly repeated and do not change for a particular species.
Animals are born with this pattern so they do not need to learn it. Fixed Action Patterns increases the fitness, survival and the reproduction abilities of the animals.

What are some questions that biologists might ask about the living things they study?
Explanation:
Five fundamental questions in biology ...
1) The origin of life.
2) The mechanisms of evolution.
3) The control of the size, both of the organs and of the living beings.
4) The functioning of the brain.
5) Aging.
Biologists might ask some questions about the living organisms they study. These questions include, but not limited to:
- What group of living organism do they belong to? Is it a plant, animal, protozoan, fungi or moneran?
- How complex is the organisms' body? is it multicellular or unicellular?
- How do the organisms feed? is autotrophic or heterotrophic?
- How do the organisms reproduce? sexual, asexual, or both?
- How do the organisms get energy? aerobic or anaerobic?
- How do the organisms move?
- How do the organisms grow?
- How do the organisms get rid of waste products from their systems?
- How long do the organisms live? What is their life cycle like?
- How do they interact with the biotic and abiotic components of their environments?
- What kind of habitats do they live?
- What role do they perform in their habitats?
All these questions and more might be asked by Biologists about the living organisms they study.

The term that would best represent X would be tissue.
The simplest level of organization of living things is the cell followed by tissue, organ, organ system, and then the organism itself.
- The cell represents the simplest unit of existence
- Cells come together form tissues in order to perform a function
- Different tissues come together to function as a unit known as organs
- Different organs make up the system and the body of an organism is made up of different systems.

The correct answer is C. Tissue
Explanation:
In the diagram, x is between organ and cell level. This implies this level of organization is smaller than an organ but no as small as one cell. In this context, the most suitable term to add to this level is a tissue because these are structures composed of specialized cells, which shows this level encloses cells. Also, a group of tissues forms an organ; this implies the organ is the level that follows the tissue. Examples of this include muscle tissue composed of muscle cells and that is part of organs including the heart.
