He observed dairymaids milking cows with cowpox to see if the statement was true before forming a hypothesis.
Explanation:
-function
Cells are the basic microscopic units of all organisms. There are two cell types:
- Prokaryotic ( meaning ➡️ pro: before and Karyon: for kernel/nut) describes organisms which don’t have a cell nucleus or other organelles surrounded by membranes.
- Eukaryotic (eu meaning true), are organisms with a cell nucleus and several other organelles surrounded by membranes.
- Example prokaryotes do not contain: nuclei , Golgi apparatus, chloroplasts, mitochondria
Both may contain a cell wall (seen in eukaryotic fungi and plant cells)
Their structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates.Organisms, are either unicellular (single- celled) or multicellular (many celled).

Answer: Chemoreceptors
Explanation:
It is Chemoreceptors because Chemoreceptors are receptors found in the pharynx and oral cavity that tranduces chemical substances or detect stimulus and send it to the brain and it is converted to biological signal. It is sensitive to chemicals like carbondioxide and detect changes in normal environment for carbondioxide increase or reduction in oxygen in the bloof and then send it to the brain for interpretation. Chemical changes I their environment stimulate them.
Answer:
A plant cell b/c it has chloroplast
Explanation:
Chloroplast absorbs sunlight also known as light energy used for the process of photosynthesis.
Answer:
chromosomes
Explanation:
DNA of organisms is organized into one or more thread-like structures called chromosomes. Chromosomes are made of DNA and its packing proteins. During cell division, the thin mass of chromatin which in turn is made of DNA and its packing protein condense and becomes visible as individual chromosomes. The DNA molecule is wrapped around histone proteins to form nucleosomes which in turn become compact into chromatin fibers.
The further condensation of looped domains formed by the coiling of chromatin fiber forms chromosomes. The part of a chromosome that holds its two arms together is called centromere. Chromosome becomes visible during the prophase stage only when condensation of chromatin takes place.
