Fossils are non living things, so the dinosaur fossil are non living thing.
A fossil is defined as the preserved remains, imprints or traces of something that once lived which includes the bones, shells, exoskeletons, stone traces of animals or microbes, amber, hair, petrified wood, and DNA from a past geological age. The totality of fossils is known as the fossil record.
Fossils are formed in many different ways by non-living things but are mostly formed when a living organism (such as a plant or animal) dies and is quickly buried by sediment (such as clay, sand or volcanic ash). Fossils show a tangible connection to life, landscapes, and climates of the past.
Thus, Fossils are non living things, so the dinosaur fossil are non living thing.

Answer:
Reflects the red light
Explanation:
The optical physics says that whatever color we perceive for any object is the color of the light of any particular wavelength that is reflected by the object instead of observing. Rest all form of light waves except the one which is reflected are absorbed or transmitted by the object. For instance – leaves appear green because they reflect the green light and this is the reason that when plants are exposed to green light they are not able to photosynthesize.
A 'red' apple does not emit red light. Rather, it simply absorbs all the frequencies of visible light shining on it EXCEPT for a group of frequencies that is perceived as red, which are REFLECTED. An apple looks red to us because it REFLECTS infrared waves.
Meiosis increases genetic variability as it produces gametes for sexual reproduction.
The process of meiosis increases genetic variability as it produces gametes for sexual reproduction. Meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes as the parent cell. During meiosis, genetic recombination and crossing over occur, leading to the production of genetically diverse gametes.

Answer: Estuary
An estuary can be defined as an ecosystem where a fresh water source like stream of river get mixed with an ocean. The water in the estuary is brackish water. In estuaries, the water level and salinity rise and fall under the influence of oceanic tides, river flow and seasons. The oceanic tides creates the largest flow of saline water whereas, rivers creates largest flow of fresh water. During rainy season the rivers will flood the estuary with fresh water and in the dry season the estuary shrinks and becomes more saline. Therefore, estuary water varies in degrees of salinity.
B) consumption
C) commensalism
D) parasitism
E) mutualism
Answer:
C) commensalism
Explanation:
because commensalism is that type of biological interaction in which members of one specie are getting benefit while the other members of other specie are not getting any benefit nor harm.
Answer:
waterway has its own particular characteristics related to water flow, velocity, and quantity.
Altered water ways or hydrology defines the variation in such characteristics including water flow. Water flow naturally depends on the climate and landscape ( valleys, mountains and flood plains).
There are several examples of people changing the way water flows such as construction of a dam or weir and the addition of a culvert or pipe. Dams are use to control the flow of water and through culvert or pipe, the flow or direction can be changed.
Changes in vegetation and landscape by people also affects the flow of water as well.
