3 redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks. One tree is left outside in normal conditions. The heights of the trees are measured once a week. What is the independent variable? What is the dependent variable? What is the control group?

Answers

Answer 1

Answer:

The correct answer is -

The independent variable - Humidity levels

The dependent variable - Height

The control group - Tree kept outside of the greenhouse

Explanation:

In this study or experiment, the independent variable is the different humidity level as it is what is changed in the study to see its effect on the growth of the redwood tree. The independent variable is manipulated in the experiment to see the change or effect in the dependent variable occurs.

The dependent variable is the variable which \depends on the independent variable as the Independent variable manipulated the dependent variable is measured to the effect which is the height of the redwood trees here.

The control group is a groub of subjects that did not get the treatment that experiment group recieves as it is kept for analysing the deviation from the natural condition. The control group is the redwood trees that are kept in natural environemnt outside of the greenhouse.

The parts of the vascular plants are roots, stems and leaves.

Vascular tissue in the  plants is  just made of the two of the specialized  types of the conducting tissues that are xylem that conducts water and phloem that conducts the  sugars and organic compounds. A single  type of the vascular bundle that  always has both xylem along with the phloem tissues.

In photosynthesis, light energy is transformed chemical energy carbon dioxide gas is released. In cellular respiration, a glucose molecule is broken down and carbon dioxide gas is released.

Explanation: Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).

Describe the processes of transcription and translation in your own words
Terms to use in your answer: amino acid, anticodon, codon, gene, messenger RNA, nucleotide, ribosome, RNA, RNA polymerase, transcription, transfer RNA, translation.

Answers

Answer:

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.

1. When a bridge-like structure forms between bacteria and genetic material is exchanged, bacteria are reproducing through which process?
A. Binary fission
B. Transformation
C. Transduction
D. Conjugation

Answers

Answer:

D. Conjugation

Explanation:

Bacterial conjugation is the transfer of genetic material between Bacterial cell by direct cell-to-cell or by bridge like connection between two cells.

The process in which the formation of a bridge-like structure takes place between bacteria to exchange genetic material is known as conjugation and thus option D is correct.

Bacteria is a prokaryotic cell and it has developed various methods for the purpose of genetic recombination. Genetic recombination is significant for genetic diversity. The 3 most common methods used by bacteria for the diversification of their DNA are namely Transduction, Transformation, and Conjugation.  

The Conjugation process is explained as follows:

The Conjugation process in Bacteria is explained as the genetic material transfer between bacterial cells by direct contact between cells or by a connection formed by a bridge-like structure between the cells. The pilus plays a significant role in forming a connection between 2 cells. With the help of the formed contact, the plasmid can be able to transfer its own copy to the recipient bacterial cell which results in exchanging of genetic material.

Thus, we can conclude that the conjugation process in bacteria can cause the formation of a bridge-like structure to exchange genetic material and option D is the correct answer.

Enzymes

Explanation:

Enzymes are the biocatalysts, which carry out the vital metabolic process in the body. The inability of the enzyme to break down a certain molecule or compound can lead to disease.

The correct answer is:

Option 1. Enzymes

The enzymes are the biomolecules, which play a crucial role in the breakdown of large molecules into simpler forms. The enzymes catalyze various metabolic cycles in the body.

The inability of the enzyme to break down a molecule can lead to severe diseases.

For instance, a disease like Gaucher disease is a rare genetic disorder in which a person body's fails to break down fatty molecules into lipids. The build-up of lipids in the spleen can give various symptoms.

The disease can be treated by giving enzyme replacement therapy or oral medication.
