Answer:
smooth endoplasmic reticulum
Explanation:
Smooth endoplasmic reticulum differs from the rough endoplasmic reticulum in not having ribosomes on its surface. The smooth endoplasmic reticulum (SER) extends from the rough ER and forms a network of membrane tubules. The function of the smooth ER is to serve as a site for the synthesis of lipids, fatty acids, and steroids such as estrogens and testosterone.
Enzymes for the synthesis of these diverse biomolecules are present in smooth ER. The smooth ER present in the muscle cells is called the sarcoplasmic reticulum. It stores the calcium ions which are released into the sarcoplasm of muscle cells during muscle contraction.
Answer:
water
Explanation:
in poor soil most of the water would get sucked up into more powerful plants [larger plants]
<h3>
Transitional fossils</h3>
Transitional fossils are any fossilized remains of a life form which show common traits to both an ancestral group and its derived descendant group.
<em> Australopithecus afarensis </em>is a hominid that represents an evolutionary transition between modern bipedal humans and their quadrupedal ape ancestors.
Similarities in DNA
All species in the world share some amount of DNA. Species that are more related to each other share bigger amount of DNA than species that are less related. For example fruit fly and modern humans share 61% of their genome and chimps and humans share 96%.
Evolution of the eye
The PAX6 gene controls where eyes develop in animals ranging from fruit flies, octopuses, to mice and humans.
Answer: Precise measurements are important for Scientific Accuracy in order to get correct results
Explanation:
Precision is how close the Agreement is between repeated measurements under the same conditions. For example, if a measured value 36.7cm has three digits, or significant figures. Significant figures indicate the precision of a measuring tool that was used to measure a value
Accuracy is how close a measurement is to the correct value for that measurement.
When taking scientific measurements it is very important to be both precise and accurate. Bad equipment, human error can give inaccurate results.
