PLEASE HELP ME - In 1839, Schleiden and Schwann began formulating a theory of cells and their role in living organisms. Over time, cell theory has been updated. Modern theory is summarized below. All known living things are made up of cells. The cell is the structural and functional unit of all living things. All cells come from pre-existing cells by division. The flow of energy occurs within cells. Cell theory explains all of the following except a. the growth of animals. b. how viruses require the cells of living organisms to survive. c. how bacteria reproduce. d. the storage of chemical energy in plant cells.
Thank You so Much

5. Why might a cell need to phagocytose?
Answer:
Phagocytosis is a critical part of the immune system. ... By knowing the enemy, the cells of the immune system can specifically target similar particles circulating in the body. Another function of phagocytosis in the immune system is to ingest and destroy pathogens (like viruses and bacteria) and infected cells.

Darwin proposed as the process that causes evolution to occur.
Answer:
natural selection
Explanation:
Darwin proposed natural selection as the process that causes evolution.
According to the theory of natural selection, the environment naturally selects for genes that confer fitness to organisms over every other gene. In other words, organisms that are able to adapt to an environment survive and contribute more to the subsequent generation while those that are poorly adapted contribute less and gradually fade away from the population.
For example, when a drug is taken a particular pathogen, the susceptible ones among the pathogen's population will die off while the ones with the resistance gene survive, reproduce, and pass on the resistance gene to the subsequent generation. Consequently, the same drug might not work at all for the new generations of the pathogen because the gene that confers fitness has been selected for.

Natural Selection

which process do plants and animals share in common?
A. absorption if water
B. cellular respiration
C. photosynthesis
D. transpiration
Cellular respiration process do plants and animals share in common. So, the correct option is (B).
What is Cellular respiration?Cellular respiration is defined as the process that occurs in the mitochondria of all living organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).
This process is a set of metabolic reactions that occur inside cells to convert the biochemical energy obtained from food into a chemical compound called adenosine triphosphate (ATP). Metabolism define as the set of chemical reactions carried out to maintain the living state of cells in an organism which can be divided into two categories:

Gravitational force multiple choice
Answer:
Option B. The force would be quartered (factor of 1/4).
Explanation:
The gravitational force between two objects can be expressed with the equation:
By analyzing the equation, we can see that if we multiply both m1 and m2 by 1/2, the resulting new F would be lower by a factor of 1/4 (as 1/2 times 1/2 equals 1/4).
Thus the correct answer is option B.

Why do disruptive selection pressures tend to favor rapid evolutionary changes?
a. They result in sudden gene frequency changes.
b. They eliminate extreme genetic traits.
c. They select for one variation of a genetic trait.
d. They result in environmental adaptation.
Answer:
The correct answer is a. They result in sudden gene frequency changes.
Explanation:
The evolution of life, its diversity, is reduced to the processes of microevolution or speciation. But not all evolutionary processes in populations end with the formation of a new species. Disruptive selection is a type of natural selection that selects against the average individual in a population. The composition of this type of population would show phenotypes (individuals with groups of traits) of both extremes but with very few individuals in between. Disruptive selection tends to increase intra-population variability and, to this end, favors individuals at both ends of the phenotypic distribution, that is, as a final result there is a break in two different populations, which can lead to speciation.
Answer:
A"They result in sudden gene frequency changes."Explanation:

when an experiment shows that two variable are closely related the experiment shows what
Answer:When an experiment shows that two variables are closely related, the experiment shows correlation between the two variables. Correlation helps to show how two variables are related and connected. Related variables are said to be correlated. For example, we can say, good health is correlated to daily exercise routine.

What change to the following molecule's structure would result in a saturated fat?
Answer:
It needs to gain a Hydrogen atom to eliminate the double bond between the two carbons.
Explanation:
Unsaturated fat has one or more double bonds in its molecule. Saturated fat has a single bond. If you want an unsaturated fat to become saturated it needs to gain more more hydrogen atoms which will eliminate the double bonds between carbons of the unsaturated fat.

Explain how an organ and organelles are related
Answer:
Just as organs are separate body parts that perform certain functions in the human body, organelles are microscopic sub-units that perform specific functions within individual cells. Organelles are specialized structures that perform various jobs inside cells.
Organelles are microscopic subunits that carry out certain tasks within individual cells, whereas organs are distinct body sections that carry out specialized tasks for the human body.
What is the relation between organ and organelles?Literally, the phrase refers to “tiny organs.” Organelles provide specialized functions to keep a cell alive, much like organs like the heart, liver, stomach, and kidneys serve specific functions to keep an individual alive.
Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization in the body, going from the simplest to the most complex.
Like an organ in the body, an organelle is a subcellular structure that performs one or more particular functions for the cell.
Therefore, organ and organelles differ in their functioning.
