Artificial Selection is a form of selection in which humans actively choose which traits should be passed onto offspring. Humans have used selective breeding long before Darwin's Postulates and the discovery of genetics. Farmers chose cattle with beneficial traits such as larger size or producing more milk, and made them breed; and although they may have known nothing about genes, they knew that the beneficial traits could be heritable. The farmers selected for certain traits in their cattle and probably noticed that the offspring were becoming more and more productive with each generation. Scientists study these traits and spend a lot of time calculating how heritable these traits can be. The more these traits are expressed in the offspring (i.e. size, milk production, etc), the more heritable these traits are said to be. Hunting is also a form of artificial selection, with the genes that humans "want" (i.e. - the biggest buck with the most points, the largest fish, etc.) being removed from the gene pool, allowing the less "wanted" genes to pass on to the next generation by increasing their odds of mating when compared to the hunted specimens.
Hope this will help.
Lipase is for digesting lipids. Without them to break down lipids, the lipids in cells can’t be used as energy source. So I would say A.
Answer:
<u>Stores DNA</u>
Explanation:
The nucleus controls all the activities of a cell. The chromatin contains the hereditary materials, DNA while the nucleolus is responsible for the manufacture of ribosomes.
Lazzaro Spallanzani's experiment is a good example of creativity, because he designed the experiment and found a new way to explore gastric juices. So...
Lazzaro Spallanzani, an Italian biologist and physicologist, was the first scientist to dissect animals for digestion trials.
He used the animals as models for humans digestive system, designed the experiment, and was the first to interpret the process of digestion.
I hope that helped ^_^
- The Venus Flytrap survives in subtropical wetlands, it is the environment the venus flytrap needs, for example on the east coast of the USA, Brazil and Argentina. This means the venus flytrap wants lots of sunlight and humid conditions.
- It also lives in places where there is a low mineral level in the soil, so it gathers these vital nutrients from catching and digesting insects.
- For reproductive purposes, the flowers of Venus flytraps usually grows on tall stalks far above the leaves. This adaption of the plant is made so the the insects pollinating the flowers do not get trapped in the leaves. This is an anatomical adaptation that affects the flowers and the stems.
