Answer:
both animals and plants are eukaryotic cells
Answer:
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
Explantion
Animal cells
Animals are made up of millions of cells. Animal cells have an irregular structure and are made up of four key parts:
Nucleus – This contains genetic material (DNA), and controls the cell's activity.
Cell membrane – A flexible layer that surrounds the cell and controls the substances that enter and exit.
Cytoplasm – A jelly-like substance where the chemical reactions happen.
Mitochondria – This is where energy is released from the food molecules
Plant cells
Plants are also made up of millions of cells. Plant cells have a nucleus, cell membrane, cytoplasm and mitochondria too, but they also contain the following structures:
Cell wall – A hard layer outside the cell membrane, containing cellulose to provide strength to the plant.
Vacuole – A space inside the cell that is used to store substances and help the cell keep its shape.
Chloroplasts – Structures that contain the green pigment chlorophyll, which are a key part of photosynthesis.

Why people get cholera in our community
Answer:
Search Results
Featured snippet from the web
A person can get cholera by drinking water or eating food contaminated with cholera bacteria. In an epidemic, the source of the contamination is usually the feces of an infected person that contaminates water or food. The disease can spread rapidly in areas with inadequate treatment of sewage and drinking water.
Explanation:
The mode of transmission of Cholera is through fecal contamination of food or water. Transmission is therefore closely associated to poor environmental management due water and sanitation issues

reproduction by cloning?
Answer:
It is the reproduction method used by organisms like plants, fungi and bacteria.
Explanation:
Examples of such organisms are hazel trees, blueberry plants, the american sweetgum etc.
I think budding, during this process a structure called a bud develops from the parent cell then later it separates itself from the parent cell to form an independent organism which is genetically identical to the parent cell..for example in a hydra..

Advocates for organic farming claim that their methods result in a number of benefits to farmers, consumers, and the environment. Scientists now plan to study the claims that organic farming advocates make by developing testable hypotheses about the economic and environmental benefits of growing organic foods. The scientists plan to collect data from farmers and other producers. Which hypothesis should the scientists use
Answer:
''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.''
Explanation:
The hypothesis i.e. ''Organic farming reduces the cost of farming that benefits the farmers economically and also better the environment.'' This hypothesis can be tested by the scientists by taking two fields in different location having same environmental conditions. One field they apply conventional farming whereas other field apply only organic materials and no chemicals. We can see that the cost on expensive fertilizers, pesticides and weedicides can't used in organic farming so it is economically benefitted to the farmers as well as no pollution occurs which happens due to the use of chemicals. Moreover, the price of organic food is 3 times higher due to its non-hazardous nature.

how are hydrogen bond similar to iconic bonds?
Explanation:
Hydrogen bonds are similar to ionic bonds because they both involve the attraction between opposite charges. ... This creates one atom with a negative charge, called an anion, and one atom with a positive charge, called a cation. The attraction between these charges hold the atoms together in an ionic bond.
Hydrogen bonds are inter-molecular bonds. The key difference between hydrogen bond and ionic bond is that ionic bonding exists between permanent anions and cations, whereas hydrogen bonds exist between partial positive and partial negative charges

define the term (1)semi-permeable membrane (2) osmosis tell the answer i will mark u as brainlist
Answer:
a)the outermost part of an animal cell that selectively allows things to pass through and come out.
b) the passing of water molecules from higher conc. to lower conc.
Answer:
(a) Semi-permeable membrane:
A semipermeable membrane is a membrane that only allows the movement of solvent molecules but restricts the movement of solute particles across the membrane.
(b) Osmosis:
The process of movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane is called osmosis.
When two nearby concentrations are different, materials will tend to spread out to equalize the concentration. For example, if you put a drop of food colouring in some water it will gradually spread through the whole water.
Which of the following is an example of a
homologous trait?
A. the wings of bees and birds
B. the forearm of different animals
C. the DNA of land animals
Answer:
A. the wings of bees and birds
Explanation:
A homologous trait is a trait that is similar morphologically and genetically to one another due to their shared ancestry. This means that the traits are formed from the same ancestors, hence, they are homologous or similar.
According to this question, the wings of bees and birds are homologous because they share the same ancestry.

3. What is spontaneous generation? a. the idea that microorganisms have the ability to sterilize lie b. the idea that microorganisms need intense heat to reproduc c. the idea that substances produce germs only when microon d. the idea that substances can produce germs on their own
Answer:
The correct answer is - d. the idea that substances can produce germs on their own.
Explanation:
Spontaneous generation is an obsolete theory or idea that supports the production of living things and substances from non-living substances and things.
This purpose is that the living creatures could arise from nonliving matter. In microbiology, it is an idea that says that substances can produce germs on their own even if the substances are not similar.
