The Phylogeny chart shows the evolution of camels. Camelus is the modern day cameo based on this chart which three statements ar

Nataly_w [17]

Answer:

Modern camels are more related to Camelops than to Aepycamelus.
Pliauchenia and Oxydactylus may share similar feautres.
Procamelus and Stenomylous may share similar features.

Explanation:

The chart given explains how the camels are evolved between Eocene (33 myo) and Pleistocene.

According to the chart, modern-day camels (Camelus) are a closer phylogenetic relative of Camelops because they are clustered together in the Pleistocene age section. However, Aepycamelus is last recorded in the Upper Miocene and later became extinct (or no record is found in Pliocene and Pleistocene).
Pliauchenia and Oxydactylus have a single ancestor "Protylopus" which can be seen in the Eocene age. Although Protylopus were branched to two species in upper Miocene, it is not difficult to believe that they share many genetic similarities (features) in both lineages.
Similarly, Procamelus and Stenomylous are the descendants of Poebrotherium and got apart at the end of the Oligocene, therefore, they will also share several features similar to each other.

What was known before Franklin and Wilkins conducted their studies of DNA? Check all that apply. DNA is found in the nucleus of

kvasek [131]

Answer:

The correct answer will be-

1. DNA is found in the nucleus of a cell

2. Organisms store and transmit genetic information

3. Cells contain protein molecules.

Explanation:

The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.

Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.

Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.

DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.

Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.

Thus, 1. DNA is found in the nucleus of a cell

2. Organisms store and transmit genetic information

3. Cells contain protein molecules.

are the correct options.

I NEED HELP ASAP IM ON A TIMER!! In what way has technology used aboard the International Space Station benefitted humans back o

Mashcka [7]

Answer:

Option 1, Robotic arms used aboard the ISS are now used in delicate surgeries on Earth.

Explanation:

The robotic arm on the international space station is used in conducting surgery. The first space robotic arm was launched in 2001 and its name was “Canadarm 2”. Though the aim of this arm was to construct space station but now a days it is used in imaging the surgical work area and instruments through its camera. The best feature of this hand is that it follows the instruction with high efficiency and precision level.

Hence, option 1 is correct.
