Answer:
A parasite is an organism that lives within or on a host. The host is another organism. The parasite uses the host's resources to fuel its life cycle. It uses the host's resources to maintain itself.
Explanation:
D. is the answer because soil and rocks are not living things
Answer:
The correct answer is 4.6 percent.
Explanation:
The Oort cloud refers to the clouds of icy objects, which is present in the outermost section of the solar system. These are the disperse layer of clouds found in the external layer of the solar system.
In the given question, it is given that the number of comets in the Oort cloud is 10^12 comets.
The number of comets getting close towards the Sun is 10 comets in a year.
The age of the solar system is 4.6 * 10^9 years
The number of comets used since the start of the solar system is,
(4.6 * 10^9 years) (10 comets/year)
= 46 * 10^9 comets
Thus, the number of comets disappeared since the beginning of the solar system is 46 * 10^9 comets.
The initial number of comets at the start of the solar system is 10^12 comets.
The percentage of comets that are used up are:
(change in no of comets) / (initial no of comets) % = (46 * 10^9 comets) / (10^12 comets) * 100
= 4.6 percent.
The nutrients from the soil is taken up by the roots
to be distributed to the entire plant. The plant absorbs the nutrients into its
cells and utilized by the leaves, stem, trunk. They are also used to grow
flowers and to bare fruits.
Moreover, the nutrients are divided into two groups;
first the macronutrients which is needed by the plants in large amount such as
nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. Second group is
the micronutrients, needed in tiny amounts that include zinc, copper,
manganese, boron, iron, sodium and cobalt. These two groups are essential for
normal plant growth and development.
Answer:
1) Basilar membrane
2) Stereocilia or hair cells
3) Nerve cells
4) Auditory
5) Temporal lobe
Explanation:
Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.
Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.
Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.
Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.
