What word is used to describe plant cells placed in a hypotonic solution?
Answer:
The answer is Plasmolysis
The word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that significantly has osmotic pressure lower than that of another solution to which it is compared. This type of solution normally contains a lower amount of solute.
According to the context of this question, when a plant cell is placed in a hypotonic solution, water will flow through it by the process of osmosis from the solution into the plant cell. This leads to cause the cell to expand or swell. But as the cell wall of the plant is very rigid, it keeps the cell from bursting.
Therefore, the word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.

B. offspring are identical to parents
C. offspring need only one parent
D. more offspring are born
Answer:
B
Explanation:
Organisms produced by sexual reproduction have two parents and are genetically similar to both but not identical to either. it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage.

What contains the instructions that tell a Cell what functions to perform?
Answer:
The nucleus contains nearly all the cell's DNA and with it the coded instructions for making proteins and other important molecules.
The nucleus contains the instructions that tell a cell what functions to perform.
What is a nucleus?In terms of genomics, a nucleus is an organelle within a cell that is membrane-enclosed and houses the chromosomes. The nuclear membrane has a variety of pores that enable the selective passage of specific molecules (such as proteins and nucleic acids) into and out of the nucleus.
The largest organelle in a eukaryotic cell, the nucleus, is thought to be the cell's command center. The majority of the cell's DNA, which makes up the chromosomes and is encoded with the genetic instructions needed to build proteins, is found in this region.
Therefore, Nearly all the cell's DNA, along with the coded instructions for constructing proteins and other significant components, is found in the nucleus.

You are an aquatic biologist studying a small lake. The stream that drains into this lake runs by croplands. You are detecting a pesticide called atrazine in the insects and worms that live in the lake. The predatory birds such as herons and egrets have very high concentrations of atrazine in their blood. The birds prey on the frogs and small fish. What condition best explains the high atrazine level in the birds?
The condition best explains the high atrazine level in the birds is biological magnification. The correct option is D.
What is biological magnification?Biological magnification is the occurrence of any chemical in the body of a living organism than in outer space or the environment. The chemicals can be toxins or pesticides. They are present within the tolerant level in the tissue.
Here, the atrazine level is high in frogs and small fish than in the surrounding water, which is going in birds.
Thus, option D. biological magnification is correct.

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.
