Answer: The correct answer to the question is option D
CAST FOSSILS.
Explanation: To understand what a cast fossil really is,let's look at what a fossil is generally.
Fossils are traces of what are formed and left of living things which dates back to a long time ago. Fossils are often found in sedimentary rocks examples; Shales, limestone and sandstone.Fossils are left over animals/plants.
Not all fossils are remains of living things.
There are different types of fossils; FROZEN FOSSILS; When an animal is trapped and freezed as a result of drop in temperature.
IMPRINT FOSSILS; They are prints made and left when animals walk or move over clays,these imprints dries and get covered by other sediments.plants also leave imprint fossils.
AMBER FOSSILS; These are fossils that are formed when tiny insects and bugs become trapped in saps of trees, when these saps dries up,they become hard and and an Amber is formed.(a seminiferous material).
CAST FOSSILS; These are fossils that form as a result of the death of plant,animal or any organism,when this happens,chemical reaction occurs which brings about a degradation in the bones and flesh if the organism,cavities are formed and minerals are deposited in those cavities bringing about a cast which looks like the original form or image of the organism.
Answer:
a) b + i = d + e
b) b + i < d + e
c) b + i > d + e
Explanation:
Data provided in the question:
b = birth
d = deaths
i = immigration
e = emigration
Now,
a) a population in equilibrium
this means increase in population is equal to decrease in population
i.e
b + i = d + e
b) b) a declining population
this means increase in population is less than decrease in population
i.e
b + i < d + e
c) an increasing population
this means increase in population is increase in decrease in population
i.e
b + i > d + e
Yes, They all are! They all can be the start of something.
Answer: Option A) sensory somatic nervous system-controls skeletal muscles
Explanation:
The somatic nervous system (SNS) is controlled by the brain, and direct conscious or voluntary actions by stimulating the skeletal muscles.
For instance: On seeing an oncoming vehicle, a cyclist will swerve to a safe path. This is a voluntary action, where the skeletal muscles are stimulated by the somatic nervous system to avoid hitting the oncoming vehicle.
