The two extinct species that share a close evolutionary relationship with humpback whales include dorudon and basilosaurus.
The similarities between these species and humpback whales include the fact that they had tailfins and their elbow joints were able to lock and this allowed the forelimb to have better control and resist the oncoming flow of water as the animal propelled itself forward.
It should also be noted that the hindlimbs of these animals were almost nonexistent and they were so tiny that many scientists think they served no effective function and may have even been internal to the body wall.
The fossil record shows whales' history from the extinct species that lived on land to cetaceans.

d, refer to a
The composition of both DNA and enzymes such as DNA lipase as they are made up of basic units called amino acids.
What is the role of enzymes in protein synthesis?When protein synthesis is taking place, enzymes link tRNA to amino acids in a highly specific manner. The third form of RNA is messenger RNA (mRNA), which receives the genetic code from DNA and carries it into the cytoplasm where protein synthesis takes place.
Thus, option "C" is correct.

How can a seedless vascular plant reproduce?
They reproduce by using xylem vessels.
They reproduce by producing flowers.
They reproduce by using spores.
They reproduce by carrying nutrients through phloem vessels.
Answer:
They reproduce using spores.
Explanation:
Seedless vascular plants (like ferns) do not have seeds. That means they do not have flowers because flowers produce fruit with seeds. To reproduce, they drop microscopic spores. These spores fly away in the wind and land wherever. Then they grow into new plants.

Explanation:
Help me please giving brainliest
Answer:
1.
air (atmosphere)
water (hydrosphere)
land (geosphere)
organisms (biosphere).
2.
The Earth's climate is created by the interaction of the atmosphere and the hydrosphere. Heat and moisture are stored in the atmosphere, whereas water vapor is stored in the hydrosphere. The interactions between the two aid in the distribution of heat and moisture around the globe, resulting in temperatures that are conducive to life.
3.
The biosphere and hydrosphere interact in the sense that the hydrosphere provides water for the biosphere to function, grow, and exist. Animals (biosphere) consume water (hydrosphere), and fish (biosphere) require water (hydrosphere) in order to survive and swim. The flood is another interaction between the biosphere and the hydrosphere.
4.
Perform experiments. Make theories. Observe. Etc.

How can the difference in temperatures influence the wind patterns in the Atlanta area?
The unequal heating of Earth's surface can cause local winds to form. The less dense warmer air rushes in to replace the denser cooler air forcing the cooler air upwards creating the local winds in a given area.

Scientists found a layer of rock with several different fossils in it, as shown in the image. Based on the model, which of these fossils are the oldest and which are the newest? Explain your answer.
Answer:
The oldest is section A, and the newest is section B.
Explanation:
First of all, the bottom most layer is almost always the oldest, because when rocks form, they don't go "hey lemme form under you", they form on top.
Second, bottom most layer is has the simplest fossils and the fossils are the same. You can see that as the higher section you go, the fossils are more complex and have more variety. Which is because of evolution.
Third, I don't know if this counts, but the bottom has the least color so I'm guessing that means that it has been decaying and whatever else you wanna call it than the other layers. Whereas the top is the most colorful, in my opinion.
