The answer is "stays the same".
Whether what kind of process the substance undergoes, the mass will stay the same. When a substance undergoes a phase change, the weight of the substance would either increases or decreases but the mass will definitely stay the same.
Answer:
It will contaminate the soil and water in the ocean.
Explanation:
This is because the oil drilling will cause oil spillage on the soil and water in the ocean. The oil spillage will cover the oil and it will not allow plant to grow there. Any crops planted there will not grow because it had release chemical and act as covering which cannot support plant growth. When it is washed into the ocean or water bodies, it can lead to death if aquatic live because it will affect the amount of oxygen that will available to them.
Answer:
The statement supported by the description of the process of protein synthesis determined by DNA and its packaging and sorted by the Golgi apparatus is that various organelles within a cell interact with each other to carry out life processes (option D).
Explanation:
From the transcription of RNA from DNA to protein synthesis and its packaging and distribution, the participation of organelles is observed:
- <em>Cell nucleus</em><em>: contains the DNA and is where the transcription into mRNA occurs.
</em>
- <em>Ribosomes</em><em>: where the mRNA is coupled to produce translation and protein synthesis.
</em>
- <em>Rough endoplasmic reticulum</em><em>: contains ribosomes and participates in the process of membrane protein synthesis, also contributing to their conjugation, glycosylation or sulfonation.
</em>
- <em>Golgi apparatus</em><em>: it is in charge of receiving synthesized proteins, packaging and distributing them to be sent to the extracellular space or other cells.
</em>
In this way, the coordination of the functions of various organelles is useful and necessary to fulfill vital functions. The statement that varoius organelles within the cell interact with each other to carry out life processes is, therefore, correct.
<em>The options for this question are:</em>
<em> A. Organelles within a cell act independently of each other at all times
</em>
<em> B. Some organelles are more important than other organelles within a cell.
</em>
<em> C. Only up to three organelles may interact with each other at any given moment in time.
</em>
<em> D. </em><u><em>Various organelles within a cell interact with each other to carry out life processes.</em></u>
Answer:
The correct answer is option b. "The receptor potential is carried by neuroglia".
Explanation:
Neuroglia is a term used to describe a class of cells which main function is to support the neurons. The term neuroglia include astrocytes, ependymal cells and oligodendrocyte. It is false to affirm that the receptor potential is carried by neuroglia, the receptor potential is carried out by the neurons.
Answer:
Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein.
Explanation:
The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.
In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1). The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.
