Answer:

<em>The correct option is C) A mouse and a human have about the same number of genes.</em>

Explanation:

The technique of genetic sequencing has enable us to learn and compare thee genomes of different organisms. Genome sequencing proves that the genome of the humans and mice are about 99 percent similar. The number of genes in the mouse genome and the genome of humans is almost equal.

Other options, like option A, cannot be true because many complex organisms have fewer chromosomes than other organisms. For example, there are many simple plants which have more number of chromosomes than the complex humans.

allsm [11]

Answer: All the statements of the question are correct.

Sickle cell disease is an autosomal recessive disorder that is characterized by formation of defective hemoglobin protein, which results in sickle shaped RBC ( red blood cell).

This disease is caused by mutation in the gene that is responsible for the protein hemoglobin ( which transport oxygen throughout body).

It is inherited by the offspring when both the mutated copy of genes ( one from each parent) are passed to him.

Carriers of the disease exhibit increased resistance to malarial parasites by controlling the level of free haem in the blood ( through enzyme heme oxygenase that produces a toxic carbon monoxide gas). The resistance thus developed, is a mutation.

Therefore, all the statements in the given question are correct.

Explain how paleoclimatologists (scientists that study climate change) use fossils and other records to study climate change.
marysya [2.9K]

Answer:

paleoclimatologists use different sources of information from fossils in order to record past climate and environmental conditions (for example, tree rings or skeletons of coral reefs)

Explanation:

Paleoclimatology is the discipline that studies ancient climate and environmental conditions. Paleoclimatologists are researchers that analyze different sources of evidence to obtain accurate records of past climate conditions. In this regard, the fossil record has proven to be a useful tool to obtain such information. For example, the rings of fossilized trees are usually wider during warm and wet years, while these rings become thinner during cold and dry years. Moreover, geochemical records from the skeletons of fossil corals (composed of calcium carbonate) are good indicators of past climate conditions because coral growth is sensitive to small fluctuations in water temperature. Paleoclimatologists also use non-biological climate indicators (e.g., sediments and ice sheets) to reconstruct past climate and environmental conditions.
