Sophie says dolphins and sharks look very similar, so they must be related. Jake disagrees, saying DNA evidence has shown that d

olphins and other aquatic mammals are actually more closely related to the ancestors of modern hippos. Who is correct using the modern system of classification?
Sophie is correct because dolphins look more like sharks than like hippos.
Jake is correct because classification is based on evolutionary relationships.
Both are correct because traditional and modern classifications can overlap.
Neither is correct because neither is taking into account both the traditional and modern systems

Answer:

Both are correct

Explanation:

The modern system classifies organisms into eight levels: domain, kingdom, phylum, class, order, family, genus, and species. The scientific name given to an organism is based on binomial nomenclature.

The "traditional" system relies on Linnean classification (what looks similar between the the two species.

What information did you include in our<br> response?
Daniel [21]

Answer:

All of the statements are true.

The X chromosome is one of the two sex chromosomes of humans and some animals (the other sex chromosome is the Y chromosome). Men have a single X chromosome and women two X chromosomes.

Diseases whose gene is localized on the X chromosome are most often transmitted in the X-linked recessive mode; some are transmitted on the dominant mode related to the X.

In this mode of inheritance, the morbid allele behaves like a recessive trait.

Women heterozygotes are not affected but can transmit the disease; they are aid to be conductive of the disease.

The disese is only manifested in male subjects (XY) with only one copy of the gene (hemizygous subjects)

How are photosynthesis and cellular respiration related apex?
pentagon [3]
Photosynthesis and cellular respiration are related in that; photosynthesis is a process that is tasked in making glucose which is then used in cellular respiration to make ATP. The glucose is then converted to carbon dioxide during cellular respiration, which is used in photosynthesis. Water on the other hand is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is  combined with hydrogen to form water.

Genes _____.
lys-0071 [83]

Answer:

The correct option is D. Genes determine the trait of an organism.

Explanation:

Option D is correct because genes can be described as the hereditary molecules that determine the characteristics of a person.

Option A is false because each gene is made up of different nucleotide sequences.

Option B is false because genes do not occur as the same number of chromosomes. Rather, there are many genes present on a single chromosome.

Option C is false because all genes are not located in a specific location. Each gene has its specific location on the chromosome which is known as its locus.

Option E is false because genes are not units of RNA. Genes are made up of DNA.

Which of the following most accurately describes the process that must occur when working with research animals covered by U.S.
kondor19780726 [428]

Answer:

The process which must occur when intending to work with research animals that are covered by the U.S federal regulations is ethical review and approval

Explanation:

Some animals had been threatened of extinction due to inconsiderate usage and killings due to either commercial, food, or research purpose. The U.S government, therefore, to prevent the extinction of such animals, formulated a law to restrict the engagement of these animals, even in research if the research will involve the slaughtering, injuring, or alter the physiological functions of the subject animals. Therefore, there has been needing to undergo a compulsory ethical review process when planning to undertake research. This process will objectively review the aims and objectives of the intended research, the methodology involved in achieving the aim, as stated in the research proposal. The importance of this review is to determine if the research will have deleterious effects on the animals, both spontaneously and in the future.

JulijaS [17]

Answer:

In explanation.

Explanation:

Gregor Mendel formulated his laws of heredity in 1860 before...

-The structure of DNA was known, the existence of chromosomes and genes were known and the mechanisms which create variation in offspring were known.

If your quiz is like this:

Question: Gregor Mendel formulated his laws of heredity in 1860 before ________.

A). The structure of DNA was known.

B). The existence of chromosomes and genes was known.

C). The mechanisms which create variation in offspring were known.

D). All of the choices above are correct.

E). An understanding of mitosis and meiosis was known.

The correct answer is the "D" because yes after Gregor Mendel formulated his laws of heredity in 1860 the structure of DNA was known, the existence of chromosomes and genes were known and the mechanisms which create variation in offspring were known. (Referring that A, B, and C are correct).

Hope this helps.
