Answer:
b. forward mutation, suppressor mutation
Explanation:
When the nucleotide sequence of an organism is altered, it is called as mutation. It can be caused by DNA damage or replication errors. In forward mutation, the wild type allele is converted to a mutant version such that the gene product is non functional or its not produced at all. Suppressor mutation is the second mutation which reverses the phenotypic effects of the previous mutation. This process is called as synthetic rescue.
Since here gene X was converted into a mutant form by the mutation, it had undergone forward mutation. When gene Y was mutated, the function of gene X was restored which ultimately also restored the phenotype hence it is an example of suppressor mutation.
Answer:
The correct answer is - Protect organs
Explanation:
The skeletal system is the internal frame of the body that includes all the bones and joints present in the body. There are 206 bones in the adult human skeletal system.
The major roles of the skeletal system to help in movement, support, and protecting vital organs such as hearts, stomach, lungs, brain, and other organs. It also helps in movement and providing support to the body.
Answer:
The haploid structure of the plant, during a stage in plant's life cycle, is known as the <u>gametophyte.</u>
Explanation:
The life cycle of plants includes a haploid generation and a diploid generation. Both the structures are multicellular.
The diploid structure of a plant is known as sporophyte. This structure produces spores via meiotic division.
Whereas, the haploid structure of the plant, known as the gametophyte, is formed from spore and produces haploid gametes.
Answer:
The statement that best describes the benefit of studying biology is the ability to intelligently debate issues such as cloning.
Explanation:
Biology encompasses the study of all known forms of life, including their anatomy, organization, functioning and interactions.
One of the advantages of the knowledge acquired through biology is to be able to participate in works and discussions involving subjects related to living beings, including cloning.
The other options are not correct because:
<em> a and c. The </em><u><em>ability to experiment on animals or preserve animals that are extinct</em></u><em> is reserved for scientists with a deep knowledge of biology and its fields.
</em>
<em> d. Understanding the </em><u><em>causes of wheather change</em></u><em> does not correspond to knowledge in biology</em>
Option A is correct. These ions then have interaction with actin and myosin filaments to purpose muscle contraction. The muscle groups stay in the shriveled state until adenosine triphosphate (ATP) binds to myosin, releasing the myosin and actin filaments from one another.
<h3>How long after a individual dies does rigor mortis set in?</h3>
Rigor mortis appears approximately two hours after dying in the muscle groups of the face, progresses to the limbs over the subsequent few hours, finishing between 6 to eight hours after death. [10] Rigor mortis then stays for some other 12 hours (till 24 hours after death) and then disappears.
<h3>Why does a body go into rigor mortis stiffen within 36 hours of death?</h3>
Rigor mortis is the 1/3 stage in which the muscle mass harden and become stiff, prompted with the aid of the lack of adenosine triphosphate (ATP), which gives electricity to the muscles. Rigor mortis is a extensive tool to any dying examination because it can narrow down the timeframe of death.
