Heredity refers to the process in which DNA is transmitted from parent to offspring, determining trait inheritance. DNA contains the genetic information that informs the traits of the offspring.
The key feature of living organisms that is best described as the transmission of DNA from parent to offspring is called heredity. Heredity is a fundamental biological process that refers to the passing on of genes from one generation to another. Within this process, DNA plays a crucial role as it contains the genetic material that determines the traits of an offspring. For example, you might have the same eye color as your mother because she passed on the specific sequence in her DNA that determines eye color

Answer:
A. Independent variable 2. dominant tree species
B. Dependent variable 3. tree survival rate after the fire
C. Controlled variable 1. thinning or no thinning before the fire elevation of the site
Explanation:
A. An independent variable doesn't undergo changes during the experiment because it is not conditioned by other variables in the experiment. In this example, dominant tree species represent a variable that is independent of the experiment itself.
B. A dependent variable is those that you need to measure and depends on the other factors in the experiment. In this example, tree survival is dependent on the factors that affect the results (i.e. humidity in the trees, presence of resinous material in the trees that are non-combustible, etc.)
C. A controlled variable is those that we use to observe an expected outcome in the experiment and therefore it is used to compare with the test group. In this case, thinning or no thinning are used as positive and negative controls, respectively, because they enable their comparison with the test group in the experiment.

Explanation:
C. Polypeptide formation.
D. Transcription.
E. Translation.
DNA, the RNA polymerase core enzyme, and the subunit are the first transcriptional components. mRNA, small and large ribosomal subunits, initiation and elongation factors, as well as tRNA, are all parts of the translation process. Thus, option D is correct.
Proteins called transcription factors are involved in the process of turning DNA into RNA, or transcribed DNA.
A large variety of proteins—aside from RNA polymerase—called transcription factors start and control how genes are transcribed.
A gene's transcription is boosted by transcription factors that serve as activators. Reducers lessen transcribing.
An enhancer or silencer is a collection of transcription factor binding sites that can turn a gene on or off in a particular region of the body.
Therefore, Transcription is the process in which a strand of DNA is used as a template for the manufacture of a strand of pre-mRNA.

Answer:
I think it is c have a good day
A.Bacteria are larger than viruses but are still small enough to enter cells.
B.Both bacteria and viruses are surrounded by protective coverings, through the composition of each covering may be different.
C. Only bacteria can acquire new characteristics, which makes them more difficult to treat.
D.Bacterial infections such as diphtheria and tetanus cannot be prevented by vaccines.
Answer: B
Explanation: Bacteria are larger than viruses but are still small enough to enter cells.
The argument supported by the information in the table is that both bacteria and viruses are surrounded by protective coverings, but the composition of each covering may be different.
The argument supported by the information in the table is option B. Both bacteria and viruses are surrounded by protective coverings, but the composition of each covering may be different. For example, bacteria have a rigid cell wall made of peptidoglycan, while viruses have a protein coat called a capsid.
This difference in composition affects how bacteria and viruses interact with their environments and how they can be treated.

Answer:The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. Some plants need more sunlight than others, but all need at least a little. Instead of taking in oxygen and breathing out carbon dioxide like animals do, plants take in carbon dioxide from the atmosphere......thank you.have a great day
