b. Head, thorax, abdomen
c. Mandible, thorax, legs
Answer:
Head, thorax, abdomen
Explanation:
It is correct
2.observing things in nature
3.making drawings of things observed
4.identifying and controlling variables
The most important part of an experiment would be; identifying and controlling variables.
In order to set up an experiment, you need to test the specimen(s) with and without a curtain variable. That is what makes an experiment a test.
Answer:
identify and controlling variables
Explanation:
lack of awareness of control variables can lead to faulty result or what are called "confounding variables" additionally, noting control variables makes it easier to reproduce and experiment and establish the relationship between the independent and the dependent variable
Answer: This function of the skin is similar to the renal system.
Explanation: The renal system, also known as the excretory system, is responsible for removing all waste products from the body which are primarily nitrogenous in nature. The skin also aids in excretion except this excretion takes place in the form of sweat.
The remainder of the renal system, however, removes other waste materials such as urea, ammonia, uric acid etc. with the help of the kidney, ureter, urethra and urinary bladder and these organs primarily deal with the excretion of solid waste material the body produces. However, part of the liquid waste is excreted by the skin in the form of sweat.
The substances secreted in perspiration, such as sodium, chloride, urea, and ammonia, are similar to the waste products excreted by the renal system.
The skin secretes substances in perspiration such as sodium, chloride, urea, and ammonia. These substances are similar to the waste products excreted by the renal system, which includes the kidneys and urinary system. Perspiration, also known as sweat, is a fluid produced by the sweat glands in the skin. It plays a crucial role in regulating body temperature and eliminating waste products.
The renal system, on the other hand, is responsible for filtering waste products from the blood and excreting them in the form of urine. Both perspiration and urine contain similar waste substances, indicating a similarity between the skin and renal system in terms of waste elimination.

Answer:
According to the punctuated equilibrium model, evolution occurs in spurts; species evolve relatively rapidly then remain unchanged for long periods.
Explanation:
The theory of punctuated equilibrium maintains that during most of the time of existence of a species it would remain stable or with minor changes, that is, in periods of stasis or periods of morphological stability, followed by rapid and abrupt events of evolutionary changes. This model was proposed by evolutionary biologist and paleontologist Stephen Jay Gould and his colleague Niles Eldrege. This theory includes the phenomena of stasis and the sudden or instantaneous appearance of forms in the normal process of speciation, that is, formation of new species.

testing to see if it has cells
