The Punnett square predicts the ratio of genotypes in the offspring based on the genotypes of the parents. Which Punnett square
Fudgin [204]

Answer:

A Punnett square is shown. The columns are labeled Upper D and d. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, d d, d d, Upper D d.

Explanation:

Punnett square is used to depict the cross between two organisms. Progeny genotypes can be determined by punnett square. Columns and rows are labelled according to the alleles present in the genotype of respective parents, in this case the mom and the dad.

It has been given that the mom is heterozygous for dimples trait. Since, heterozygous genotype has two different alleles together, mom's genotype must be Dd. Dad is homozygous for no dimples so he can either be DD or dd depending on the dominance nature of the trait. Out of the given options, only the selected option has one heterozygous genotype (Dd) and one homozygous genotype (dd) together hence it is the correct option.

Dina is a paleoclimatologist. she wants to review documents to assess climate data for her hometown. which historical documents
lana66690 [7]

Newspaper articles and farmers harvest yield record are the documents should Dina examine in order to assess this climate data.

Among atmospheric scientists is a group known as paleoclimatologists. There were 11,800 workers in this field in 2014, albeit not all of them were climatologists or paleoclimatologists, according to BLS data. With 40% of the workforce, professional, scientific, and technical services was the main employer of atmospheric scientists.

<h3>What level of education is required to work as a paleoclimatologist?</h3>

Your future work as a paleoclimatologist will involve a lot of biology, physics, and other hard sciences, thus there are lots of degree programs that mix these fields with the environment. Environmental biology and environmental chemistry are two examples of such options.

<h3>How far into the past can paleoclimatology take us?</h3>

Paleoclimatology makes extensive use of polar ice sheets and ice caps as well as mountain glaciers. Data from ice-coring efforts in the ice caps of Greenland and Antarctica date back over 800,000 years in the case of the EPICA project, or several hundred thousand years.

<h3>Why is paleoclimatology essential and what does it entail?</h3>

Our knowledge of Earth's climate depends on the science of paleoclimatology. Scientists can create models to help predict how rising carbon dioxide levels and other changes can affect the climate of Earth in the future as they become more aware of how climates have been influenced in the past.
