Oxygen has an atomic number of 8. The n=1 energy level has two electrons, and the n = 2 energy level has six electrons. Oxygen's valence is _______.
● +2
● -2
● +1
● -1
Answer:
Oxygen's valence is +2
the answer is +2
I hope this helps
Answer:
● -2
Explanation:
Oxygen needs to gain 2 more electrons to have 8 electrons in outer most shell (octet rule). Gaining electrons makes you negative thus, oxygen gains 2 electrons and has valence of -2.

The Darwinian theory of organic evolution through natural selection affected American religion by a raising awareness of the close spiritual kinship between animals and human beings. b turning most scientists against religion. c causing a revival of the doctrine of original sin. d sparking the rise of new denominations based on modern science. e creating a split between religious conservatives who denied evolution and accomodationists who supported it
Answer:
.e creating a split between religious conservatives who denied evolution and accomodationists who supported it
Explanation:
The Darwinian theory of organic evolution proposed that all forms of life evolved from more primitive life by differential survival and reproduction (i.e., by natural selection). Moreover, creationism is the religious belief that humans were created by God, whereas accommodationists refer to the persons that endorse cooperation and concession to the viewpoint of the opposition. In this case, Darwinian theory challenged the traditional religious anthropocentric viewpoint on human origins (i.e., humans descended from ape-like creatures by natural selection).
The invention of the microscope led to the discovery of the cell by Robert Hooke. While looking at cork, Hooke observed the box-shaped structures, which he called "cells" because they reminded him of the cells (rooms) found in monasteries. This discovery led to the development of the cell theory. Credit for developing the cell theory is usually given to two scientists. Theodor Schwann and Matthias Schleiden. The cell theory was then proposed by Theodor Schwann in 1839. There are three parts to this theory: living organisms are made up of cells, cells are the basic structural unit of all organisms, and all cells come from pre-existing cells. Which of these is supported by the tenets of the cell theory? Select ALL that apply. les )) A) Energy flow occurs within cells. B) Mitosis produces identical daughter cells. C) Living organisms can be unicellular or multicellular. D) DNA is copied and passed between cells during cell division. E) Single-celled bacteria grow and then divide in half to make new bacteria.
Living organisms are made up of cells, cells are the structural unit of all organisms, cells come from pre-existing cells Energy flow occurs within cells.
What are the main points of cell theory?The main points of cell theory are:
All living things are made up of cells.Cells are the raw building blocks of life.All cells come from preexisting cells through the cycle of cell division.Energy flow occurs within cells.Thus, cells come from pre-existing cells Energy flow occurs within cells.

What is the job of the enzyme telomerase?
Answer:
Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences. Telomerase activity is exhibited in gametes and stem and tumor cells. In human somatic cells proliferation potential is strictly limited and senescence follows approximately 50-70 cell divisions.

When an organism such as a yeast lives by fermentation, it converts the pyruvate from glycolysis into a different compound, such as alcohol. Why doesn't it secrete the pyruvate directly? Group of answer choices The conversion yields one NADH per pyruvate molecule. A buildup of pyruvate in the surrounding environment would be too toxic. The conversion is needed to regenerate the molecules needed for glycolysis. The conversion yields 32 ATP per pyruvate molecule.
Answer:
The conversion is needed to regenerate the molecules needed for glycolysis
Explanation:
Fermentation is a metabolic process by which microorganisms generate ATP by the anaerobic (without oxygen) degradation of organic nutrients. Fermentation allows to microorganisms convert carbohydrates into alcohol or acid. During glycolysis, two NAD+ molecules are reduced and glucose molecules are split into two pyruvate molecules, thereby producing two NADH molecules and two ATP molecules. During fermentation, pyruvate molecules are metabolized to different compounds because the energy stored in the pyruvate molecules is unavailable to the cell. In fermentation, NADH from glycolysis is oxidized back to NAD+ by being used to reduce pyruvate or a pyruvate derivative.

plz help!!! Gall flies lay their eggs in developing shoots of the tall goldenrod. When the fly larvae hatch, they release chemicals that cause the plant tissue to swell around the larvae, causing a resultant gall to form. The gall flies are prey for the parasitic wasp that lays its eggs in the smallest galls. After the wasp larvae hatch, they eat the fly larvae. The gall fly is also prey for the downy woodpeckers that feed on the larvae of the largest galls. Which type of natural selection may the gall fly be subject to?
Directional selection
Disruptive selection
Normal distribution
Stabilizing selection
im so confused
Answer:
stabilizina selection
Explanation:
As given in the question, the galls may be smaller or larger. However the eggs laid in smaller gallsare prey to wasps, hence they are destroyed
