Answer:
The correct answer will be-
1. make an observation
2.ask questions
3.construct a hypothesis
4. test the hypothesis
5. analyze the results
6. make conclusions
7.communicate the results
Explanation:
A scientific method is a systematic approach to answer and explain the natural phenomenon of nature.
The scientific method begins with making an observation based on which the researcher can frame scientific questions which could be answered. The researcher must do background research on the same question and predict the most probable reason in the form hypothesis.
This hypothesis must be tested by performing the experiments designed to test the hypothesis. Based on experiments results must be collected and analysed as a piece of evidence to make conclusions regarding the hypothesis. These results must be communicated through poster presentations or in published form in journals after peer-reviewed.
Thus, the steps are arranged in accordance with the scientific method.
The sequence of steps in a scientific investigation includes making observations, asking questions, constructing a hypothesis, testing the hypothesis, analyzing the results, and communicating the results.
The sequence of steps in a scientific investigation is as follows:

Answer:
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction. The endocrine system regulates how much of each hormone is released.
The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In humans, the major endocrine glands are the thyroid gland and the adrenal glands.
B)speciation
C)convergent selection
D)stabilizing selection
Answer:
B)speciation
Explanation:
Speciation is the term used to refer to the division of a lineage that produces two or more different species. In a nutshell, we can say that this is the process of the emergence of a new species, and the crucial event for this to happen is reproductive isolation. This reproductive isolation impedes the gene flow, therefore, obeying the biological concept of species, we say that a new species has emerged.
An example of speciation is shown in the question above, where a volcano separated two species and left them in reproductive isolation. The result of this was that two populations became so different from one another that they became unable to breed, creating new species.
B is the correct answer for e2020
O cells found in prokaryotes
O complex cells found only in plants
O the reproductive cells of an organism
Answer:
the reprodutive cells of an organism
Explanation:
sex cells= gametes
somatic cells=body cells
simple cells (no nucleus)= cells in prokaryotes
Answer:
Hydrophobic molecules don't like water,just like the membrane.Since the membrane and these signaling molecules are made of the same thing,liquid,they can easily mix together.
Explanation:
Hydrophobic signalling molecules move right through the cell membrane to the target inside the cell.
