there are many diiferent types of scientists
Answer: Biological polymers are large molecules composed of many similar smaller molecules linked together in a chain-like fashion. The individual smaller molecules are called monomers. When small organic molecules are joined together, they can form giant molecules or polymers. These giant molecules are also called macromolecules. Natural polymers are used to build tissue and other components in living organisms.
Generally speaking, all macromolecules are produced from a small set of about 50 monomers. Different macromolecules vary because of the arrangement of these monomers. By varying the sequence, an incredibly large variety of macromolecules can be produced. While polymers are responsible for the molecular "uniqueness" of an organism, the common monomers are nearly universal.
The variation in the form of macromolecules is largely responsible for molecular diversity. Much of the variation that occurs both within an organism and among organisms can ultimately be traced to differences in macromolecules. Macromolecules can vary from cell to cell in the same organism, as well as from one species to the next.
Explanation:
Answer:
D. The depth of the rock layer in which the fossils are found
Explanation:
Size is irrelevant because a t-rex and ancient hamsters lived together
Color is irrelevant, because with time, almost all fossils are a grey tone look
D.) is the better answer between C.) & D.) because layers of the earth are used in the approximation of the time period in which the dinosaur lived
Answer:
in science Observation is essential in science. Scientists use observation to
collect and record data, which enables them to construct and
then test hypotheses and theories . Scientists observe in many
ways – with their own senses or with tools such as microscopes,
scanners or transmitters to extend their vision or hearing
Answer:
by phenotypically identifying plants unable (or with an altered ability) to synthesize auxins. This approach is called reverse genetics
Explanation:
Reverse genetics is a strategy widely used in molecular genetics aimed at analyzing the function of target genes by identifying defective phenotypes of one or more organisms following the disruption of the gene. In this case, a mutagenesis approach (i.e., irradiation with X-rays) was used to induce mutations in the gene/s involved in auxin production. Subsequently, the resulting mutant phenotypes, i.e., plants with an altered ability to synthesize auxin, can be used to reveal the biological function of individual (mutated) gene sequences.
