Answer:
Top to bottom: 5, 3, 2, 4, 1
Explanation:
I'll take a shot! Here I go!
5 (Sun) = top; we get all our energy from the sun
Then 3 (plants); plants can convert sunlight into food for themselves via photosynthesis
Then 2; we're talking about herbivores that eat plants, right?
Then 4; these are probably~ carnivores
Then 1; when a living thing dies, these guys consume the corpse and return the energy to the ecosystem
Have a great day!
The statement "All organisms appeared on Earth at the same time and remained unchanged throughout history." is just a saying, it does not have any scientific evidence.
And in above option,
'A' shows about scienticific data but there is no any science in statement.
'C' shows Mendel's work with pea plant which is a scientific experiment.
'D' shows Lamarck's idea which is also based ob science.
Therefore, the answer is religious beliefs

Answer:</h2>
Blood Is A Heterogeneous mixture.
<h2>
Explanation:</h2>
Heterogeneous mixture is a mixture that is made up of different substance that remains physically separated which means the cell organelles (Red blood cells, white blood cells, platelets etc.)present in blood does not mix completely and hence get precipitated after kept still for a while.
There are three ways to identify a Heterogeneous mixture.
- It has chunks of stuff that you are able to see with your eyes.
- It appears cloudy(blur).
- After a while, the substance will separate into layers at settle at the bottom(gets precipitated).
Result: Blood is a Heterogeneous mixture
Answer:
The correct answer will be option- D.
Explanation:
Neurons are the cells which help in the transmission of the signals to and fro from the CNS and PNS to the body and vice versa. The structure of the neurons is divided into three main parts: the axon, dendrites and the cell body. The dendrites and axons are the extensions of the cell cytoplasm and together constitutes the neurites.
The dendrites are the extensions of the cytoplasm which receives the signals either from the cell surface as well as the from the post-synaptic neurons and further process the signals.
Thus, option- D is the correct answer.
Ans.
Cell-to-cell communication allows signalling of essential substances between the plant cells, which are surrounded by cell walls. The molecules used by plants for long-distance signalling are known as hormones, such as auxin, ethylene, and gibberelin.
These hormones are secreted by one plant cell and received by another plant cell, where it exerts it affect. Thus, the correct answer to be fill in the blank is 'option A). hormones.'
