How can DNA be useful in phylogeny? Question 14 options: A) DNA from every organism in a clade is sequenced to identify genetic
Delvig [45]

Answer:

The correct answer is - option B. DNA sequences from different species can be compared, giving us more information about their evolutionary relationships.

Explanation:

The study of the evolution of a species in a longer period of time and its evolutionary relation with other species is phylogeny. DNA is the basis of the molecular phylogeny of a species to find out the evolution of species.

Genetic mutations, a sequence of nucleotides, and other information of DNA helps in the establishment of divergence from common ancestry. By comparing the information it gives an idea about the evolutionary ancestry of two or more species.

Explain the purpose of the placenta and describe how a fetus gets its nutrients.
marusya05 [52]

Answer:

The placenta is the temporary association of fetus and maternal tissue. It is meant for nutrition and transport of different substances.

Explanation:

The placenta is a temporary association of fetal and maternal tissues. The placenta is formed from the trophoblast of the blastula. These trophoblasts   form chorionic villi which later forms the placenta. The chorion and allantois also take part in the formation of the placenta. Hence, the human placenta is known as the chorioallantoic placenta. The process of formation of the placenta is known as placentation.  

The placenta has several functions but the major function is to provide nutrition to the fetus. The developing fetus gets nutrition from the mother's body by the placenta. The placenta provided with blood vessels which help in the transportation of different substances. It also helps in gas exchange between the mother and baby. Thus it plays a vital role in fetal respiration. The metabolic wastes diffuse through the placenta. Placenta also stores fat, glycogen, which participates in protein metabolism.

Viktor [21]

Answer:

The overall chemical reaction of cellular respiration converts one six-carbon molecule of glucose and six molecules of oxygen into six molecules of carbon dioxide and six molecules of water. ... So the carbons in the glucose become oxidized, and the oxygens become reduced.
