A classmate argues that Schwann and Schleiden are responsible for the cell theory. How do you respond? Cite facts and use logical reasoning to support your argument.
Answer:
Yes.
Explanation:
Yes, Schwann and Schleiden are responsible for the cell theory, both the scientists presented the cell theory in 1839. I agree with the argument of my classmate because the person who first presented cell theory was both Schwann and Schleiden. Schwann works on plant cell whereas Schleiden works on animal cell and formulate cell theory. So my classmate's argument is right about cell theory.
Schwan and Schleiden proposed the first cell theory, suggesting spontaneous generation. Virchow changed it proposing cell division. After many years and the contribution of many researchers, the modern cell theory emerged.
---------------------------------------------------
Schwann studied animal tissues. Through careful observation, he concluded that all animal tissues were made of cells.
Simultaneously, Schleiden arrives at the same conclusion when studying vegetable tissues.
Around 1830, they met and together proposed the first cell theory. The theory stated that:
1. Every living being is made of cells.
2. Cell is the basic unit of life.
3. Cells are originated from spontaneous generation.
Virchow, who studied human tissues, sow the cell in its dividing process.
He proposed that cells were not originated from spontaneous generation, as Schwann and Schleiden had stated.
Instead, he said that cells were the product of other pre-existing cells and were originated by cellular division.
Virchow rejected the third state of Schwann and Schleiden’s ideas.
According to these sequence of events, the original cell theory changed to
1. Every living being is made of cells.
2. Cell is the basic unit of life.
3. Cells are originated by cellular division.
After many years of continuous studies about cells and their functions, the modern cell theory emerged.
In general terms, the modern theory can be resumed as,
1. Every living being -unicellular or multicellular- is made of cells, which are the most basic units of life.
2. Cell control the vital functions of organisms.
3. Cells proceed from preexistant prokaryotic cells, and are originated by cellular division.

Photosynthesis and cellular respiration both involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes
Answer:
You have no options for me to choose from, but I'm going to make a wordy response anyway. The answer is stated below:
Explanation:
Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
What is photosynthesis?Photosynthesis uses carbon dioxide and releases oxygen and cellular respiration uses oxygen and release carbon dioxide.
Photosynthesis is the process in which green plants prepare their own food in the presence of sunlight and light energy is converted into chemical energy by the process of cellular respiration.
The process of photosynthesis takes place in green plants only due to presence of chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis.
The equation of photosynthesis is represented below:
6CO2+ 6H2O - C6H12O6 + 6O2
The process of food manufacturing in plant is done through photosynthesis and the plants are known as autotrophs as they are the producers.
In the process of photosynthesis the reactant have 6 carbon dioxide molecules and six water molecules, and light energy converted into chemical energy due to presence of chlorophyll.
Therefore, Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.

Which statement best describes why the body tries to maintain homeostasis?
O The body must maintain homeostasis so that the internal environment matches the
outside environment
The body must maintain homeostasis so that the internal environment stays the same if the outside
environment changes.
The body must maintain homeostasis to make sure that a person's heart and respiration rates are
the same.
Answer:
I would go with B:
The body must maintain homeostasis so that the internal environment stays the same if the outside
Homeostasis is the process of a state of steady internal, mental, chemical, and physical conditions of the body.
The correct answer is:
Option B. The body must maintain homeostasis so that the internal environment stays the same if the outside environment changes.
Homeostasis can be explained as:
It is the self-regulating process in which the body tends to keep the internal, physical, and chemical conditions of the body in a steady and equilibrium state. It generally refers to the stable internal conditions or maintaining the steady phase of the body with respect to changes in the environment. Sweating is one of the processes in which the body tends to maintain homeostasis by releasing excess heat in the hot climate.
Thus, the correct answer is Option B.

Why do two children from the same parents have similar structures but different genetic traits?
The two children receive different combinations of genes from their parents due to meiosis and fertilization.
The two children receive the same chromosomes from each parent due to mitosis and cytokinesis.
The two children grow up in a similar environment but are exposed to different learning experiences.
The two children develop the same mutations in their DNA but do not express mutations that impact physical characteristics.
Answer:
has to do with the fact that each parent actually has two different sets of genes. And that each parent passes only half of their genes to their child. And that the half that gets passed down is random. All of this together ensures that each child ends up with a different, unique set of genes. Hope it helps!!
