which of the following steps happens first during transcription?
Answer:
RNA polymerase attaches to the promoter.
Explanation:i just did it
The following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option (B), as the beginning of a gene is the promoter.
What is the significance of the transcription initiation?Transcription initiation has many implications, such as the fact that prokaryotic initiation is different from eukaryotic initiation, where the RNA polymerase first binds at the promoter site of the gene, where it starts moving towards the gene, and then after reaching the termination site, the transcription stops. In this process, the final product is mRNA from DNA.
Hence, the following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option, as the beginning of a gene is the promoter.

What condition is required for fermentation to occur? A. When oxygen levels within a cell are too low for aerobic respiration B. When the energy production cycle ends of the Krebs cycle C. When a glucose molecule needs to break down completely D. When 20 molecules of ATP are needed\
Answer:
A. When oxygen levels within a cell are too low for aerobic respiration
Explanation:
Fermentation is a chemical or metabolic process that occurs in organism, when a carbohydrate such as glucose is metabolized or converted to an alcohol anaerobically (absence of oxygen).
When an organism lacks oxygen within the cell, aerobic respiration would be halted, hence pyruvate produced from glucose further undergoes fermentation anaerobically.
Organisms like lactic acid bacteria and yeast carry out fermentation. The process of fermentation is widely used in food industries, such as in brewing of wine or manufacture of yogurt.

A student was observing slides of cell division. In one of the slides, he noticed loosely coiled chromatin depicting DNA duplication. Which phase of the cell cycle could it be?
A.
S phase
B.
Metaphase
C.
M phase
Answer:
A. S phase
Explanation:
The cell cycle involves all the series of division events that occurs to an organism. Cell division, which can be meiosis or mitosis, involves two main stages viz: Interphase and M phase.
Interphase describes the resting stage of the cell i.e. when the cell is not dividing. The cell uses this time to prepare itself for the next round of division. Interphase stage further consists of three main phases viz: G1, S and G2 phases.
In the S phase or synthesis phase of Interphase, the cell duplicates its genetic material (DNA). Hence, an onion cell observed by a student to have loosely coiled chromatin depicting DNA duplication is in the S-PHASE.

1. What are the 2 ways producers can produce food energy?
Answer:
Photoautotrophs and Chemoautotrophs.
Explanation:
The Photoautotrophs process uses sunlight or photosynthesis.
The Chemoautotrophs process uses chemicals.
Which statement best describes the relationship of photosynthesis and energy?
The process of photosynthesis is energy-storing because the process converts light energy into chemical ene
stored in the bonds of glucose.
The process of photosynthesis is energy-releasing because the process converts light energy into free energy
used for cell functions.
The process of photosynthesis is energy-conserving because no energy is used throughout the process of for
glucose and oxygen molecules.
The process of photosynthesis is energy-wasting because photosynthesis is an inefficient process that deplet
energy stored in the bonds of glucose.
Answer:
The process of photosynthesis is energy-releasing because the process converts light energy into free energy
used for cell functions.

How is water introduceed into rivers and streams
Answer:
As the water flows down, it may pick up more water from other small streams, springs or or from rain or snow melt. ... Small rivers and streams may join together to become larger rivers. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake.Water can be introduced into rivers and streams through surface runoff, springs, groundwater discharge, melting ice and snow, and precipitation. ... The water at the source of the river has high oxygen content, but the width and depth are typically less than they are in the middle sections. The most simplistic answer is that all the water in a river comes from the sky—and that is certainly true, as streamflow is one part of the water cycle. It is also true that most of the water flowing in rivers comes from precipitation runoff from the surrounding landscape (watershed).

5. The occurrence of large or small beak sizes among seed crackers in the absence of
medium sized beaks is an example of
I
a. directional selection.
b. stabilizing selection.
c disruptive selection.
d. none of the above.
Answer:
Disruptive selection
Explanation:
Disruptive selection favors both of the extremes ( large and small beaks) Thank me later:)
The occurrence of the large or small beak sizes among the seed crackers is the illustration of disruptive selection.
What is disruptive selection?It is the kind of natural selection, which is bimodal and favors both the extremes traits within a population. It is a kind of natural selection, which opts against the average individual within a population. This kind of selection would show the phenotypes demonstrating both the extremes, however, exhibit very less individuals in the middle.
A classic example of disruptive selection is the size of the beak of the finches on the Galapagos Islands. As the majority of the seeds found these islands were either small or large, therefore, finches with small and large beaks were favored on those islands.
Thus, the correct answer is option c, that is, disruptive selection.
