Answer: A cell is defined as the smallest functional units of the body
Explanation:
These cells are grouped together to form tissues, each of which has a specialised function, example blood, muscles, bone. Different tissues are grouped together to form organs with a special function. For example heart is an organ made up of muscles tissue, connective tissue, nervous tissue and vascular tissue. These tissues work in a coordinated manner and enable the heart to carry out the broader function of pumping blood continuously.
While organs are grouped together to form systems, each of which performs a particular function that maintains the body Internal environment and contribute to the health of the individual. For example the digestive system is responsible for taking in, digesting and absorbing food which involves a number of organs, including the stomach and intestines.
Therefore the statement that 'organs are large structures that keeps us alive" is a correct claim.
The answer is -1 you pretty much have the right answer
Answer:
C Bacteria provide nitrogen
Answer:
Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.Explanation:Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water.

In biology, a spore is a reproductive structure that is adapted for dispersal and surviving for extended periods of time in unfavorable conditions. Spores form part of the life cycles of many bacteria, plants, algae, fungi and some protozoa
