Answer:
The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.
Explanation:
Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.
Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.
Answer:
If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color:
Independent: <u>temperature</u>.
Dependent: <u>leaf color</u>.
Other variable(s): According to the information, <u>there are no other variables</u>.
Explanation:
When formulating a hypothesis, it is inevitable that the presence of variables on which the hypothesis is formed is established. The hypothesis raised is the <u>effect of temperature on the color change of the leaf of a plant</u>.
The<em> independent variable</em>, used in research work, is an element that does not depend on other variables but can influence the behavior of the dependent variable. In this case, the independent variable is the temperature. In addition, the independent variable can be managed to observe its effect on other variables.
An <em>dependent variable</em> is a characteristic that is influenced or modified by the presence of other variables, such as the independent variable of a study. In this case is the color of the leaf of a plant.
Answer:
The template strand is the antisense strand or non-coding strand with polarity in the direction of 3' to 5' end which codes for the primary RNA molecule.
The template strand codes for the proteins through transcription and translation. The transcription creates a copy of the sense strand in the form of RNA as RNA polymerase binds the promoter and adds nucleotides in 3' to 5' direction.
The mRNA molecule formed as a result of transcription contains code in the form of codon or triplets of nitrogenous bases which are read by the ribosomes and specific amino acids are added to the growing polypeptide chain via tRNA molecule.
Thus, a template strand codes for amino acids.
