Answer: The correct answer is-  bone structure of the baleen whale and the hummingbird share common ancestor.

Bone structure of the baleen whale and the hummingbird are the homologous organs.

Homologous organs can be described as the organs of different animals, which possess same basic structure but perform different functions.

For example- The flippers of a whale and forelimb of man, bone structure of the baleen whale and the hummingbird.

Baleen Whales and hummingbirds have a basic tetrapod skeletons, which is inherited from a common ancestor. But their bodies have been modified and they have lost parts through natural selection. This results in different adaptation in the form of their respective lifestyles over many years.

Nina [5.8K]

Answer:

The correct answer is D) requires phosphorylase activity.

Explanation:

Signals transmitted with the use of phosphorylation requires the presence and activity of an enzyme phosphorylase (also called Kinase) that can add phosphorus groups to proteins or other molecules in order for them to become messengers in the signaling pathway.

Consider a field plot containing 200 kg of plant material. Approximately how many kg of carnivore production can be supported? A
mixas84 [53]

Answer:

E) 2

Explanation:

The energy transfer through the food chain is not 100% from one consumer to another, or from the producer to the primary consumer, but instead it is around 10%. This means that if a producer has the 100% of energy, as it is the one that produces it, the primary consumer will only get 10% of its energy while consuming it, while the predator of the the primary consumer will only 10% from the primary consumer, or rather only 1% from the energy of the producer. In this case we have 200 kg of plant material. The plant material represents a producer, thus it is the one with 100% of energy. A herbivore will eat the plant material, getting 10% of its energy, thus this plant material is supporting about 20 kg of herbivore. The predator of the herbivore gets only 10% from the herbivore's energy, or only 1% of the producer's energy, thus only 2 kg of predator can be supported by the initial plant material.

Appositional growth occurs within the ____________ . In this process, ____________ in the inner cellular layer of the periosteum
BaLLatris [955]

Answer:

Appositional growth occurs within the periosteum . In this process, osteoblasts in the inner cellular layer of the periosteum produce and deposit bone matrix within layers parallel to the surface, called external circumferential lamellae. These lamellae are analogous to tree rings: As they increase in number, the structure increases in diameter. Thus, the bone becomes wider as new bone is laid down at its periphery. As this new bone is being laid down, osteoclasts along the medullary cavity resorb bone matrix, creating an expanding space.

Explanation:

The blanks shown in the question above were filled with the correct term for each situation, thus creating a message with veracity and with the right concepts, creating an efficient, explanatory and direct message, showing exactly what happens in the situations shown in the question. In addition, the blanks were filled with the correct grammar and the necessary punctuation to make the text cohesive.

.The pollen-producing structures of gymnosperms are locked away in cones and generally not accessible to insects. What mechanism
jeyben [28]

Answer:

Wind

Explanation:

Gymnosperms can be described as plants which lack flowers and fruits.

As they do not have flowers to attract insects like the angiosperms, they can, however, transfer their pollen through the wind. As pollen is very light in weight hence, it can be transported by the wind. The pollen transported by the wind usually results in self-pollination as the wind is not able to take the pollen to long distances.
