What are the levels of organization in the human body, starting with the cell?
Answer:
cells
v
tissues
v
organs
v
organ system
v
organism
cells make tissues that build up organs to build a organ system then organism (you,a human)
cells are the building block for life
The level of organization in the human body initiates with the cell and process in the manner which is as follows:
Cell < Tissue < Organ < Organ system < Organism. What is the level of organization?The level of organization may be defined as the process of sequence from the structures that are simplest in nature. It is usually defined by part-whole relationships, with things at higher levels being composed of things at the next lower level.
In organisms, a cell is the fundamental structural and functional unit of life. The collection of cells constitutes the formation of tissue which makes an organ that plays a specific function. Groups of organs form organ systems. While all cells, tissues, organs, and organ systems combine in order to form multicellular organisms.
Therefore, the level of organization in the human body initiates with the cell and processes in the manner which is well-described above.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
Someone please just explain this question
Answer:
The “recommended temperature limit” indicates limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..
organisms are classified as either prokaryotes and eukaryotes.which of the following do the cells of all prokaryotes and eukaryotes contain?
Answer:
Prokaryotes contains a single chromosome and DNA whereas eukaryotes contain true nucleus and organelles.
Explanation:
The cells of all prokaryotes contains a single chromosome and a double-stranded DNA while on the other hand, nucleus and other organelles are absent whereas eukaryotes contain true nucleus and organelles such as golgi bodies, endoplasmic reticulum, lysosomes, ribosomes, vacuole and mitochondria. True nucleus means the membrane is present around the nucleus.
Answer: A plasma membrane and cytoplasm

how does natural selection affect different variation of the same species?
Answer:
Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
Explanation:
Through this process of natural selection, favorable traits are transmitted through generations. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

Describe how some cells make food molecules
Answer:
All living cells release energy from food molecules through cellular respiration and/or fermentation. Some cells make food molecules using light energy through the process of photosynthesis
Explanation:
basiclly light and some cells eat others
Answer:
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.

A researcher found that the wild species of almond trees contains a chemical called amygdalin.
This chemical is converted into cyanide inside the human body and can be lethal. The researcher
found that a single gene mutation in some of the wild almond trees resulted in a variety that no
longer produced the chemical amygdalin. This variety of almond is largely harvested for human
consumption. Based on the study, the researcher claimed that some mutations are beneficial in
nature. Was the claim made by the researcher correct? Why or why not?
a) Yes. The mutated variety of almond was edible.
b) No. Not all almond trees produced seeds that were edible.
c) No. The mutation did not affect all varieties of almond trees.
d) Yes. Almond trees with amygdalin grew only in forests.
Answer:
a) Yes. The mutated variety of almond was edible.
Explanation:
Yes, the claim made by the researcher is considered correct because the mutation removes the amygdalin chemical from the almond so these almonds are now safe for eating. This removal only occur through mutation. Mutation is the sudden change occur in the DNA of cell that leads to different functions occur in the body so we can say that some mutation that is occur in organisms are beneficial.
