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.

Fossils are the preserved remains, or traces of remains, of ancient organisms. Fossils are not the remains of the organism itself! They are rocks. A fossil can preserve an entire organism or just part of one
What order do these go in?
A-Chromosome
B-Nucleus
C-Cell
D-Gene
These aren't in order. I just need to know what order to put them in.
Answer:
Cell
Nucleus
Chromosome
Gene
I guess
Answer:
The order from smallest to largest is nucleotide,gene,DNA,chromosome,nucleus,cell,organism
Explanation:
Nucleotide the buiding blocks of DNA are the smallest among the given options.DNA is bigger than gene but smaller than chromosome as DNA fits within a chromosome.
On the other hand chromosome is present within the nucleus.Nucleus along with cytoplasm and various cell organelles builds a cell.
Many cells are specifically arranged to form an organism.

Explain your justification for the changes in trait distribution between years 1 and 10. What do you think will happen to the population by year 15?
Answer:
It will continue to rise.
Explanation:
Genetic variation results in the changes in trait over the period of time. Hence, traits do change over the years, but it is a gradual process. The population will become more stable due to successful traits.
What is genetic variation?Genetic variation refers to the changes in the genotype of an individual. It imparts stability to the population. Genetic variation results from meiotic cell division where recombination of gene produces genetic exchange of heredity material.
Those traits which are successful in nature that means those variations which provide stability to the organism in any environment are favoured. Organisms with such variations adapt, survive and further reproduce to continue their existence. Such traits are transmitted to the progeny as well.
Thus, gradual accumulation of changes in traits contribute to a more stable population over the span of years.
Therefore, changes in traits are important in determining the track of evolution on earth.

Cancer cells do not respond to signals
that regulate what process?
A. transcription
B. cell cycle
c. metabolism
Answer: Cell cycle, B
Cancer cells do not respond to the signals that regulate the process of cell cycle. The correct option is B.
What signals do cancer cells respond?Cancer cells do not respond to signals that regulate the cell cycle. The cell cycle is the process by which cells grow, divide, and create new cells. Normally, cells are tightly regulated by signals that tell them when to start and stop the cell cycle.
However, cancer cells have mutations that allow them to ignore these signals and continue dividing uncontrollably. This leads to the formation of tumors and the spread of cancer throughout the body.
Cancer cells often ignore signals that regulate the cell cycle, leading to uncontrolled growth and division, which ultimately contributes to the formation of tumors.
Therefore, the correct option is B.
