Answer:
birds
Explanation:
<em>Archaeopteryx</em> is an iconic fossil bird that lived during the Late Jurassic, approximately 150 million years ago. <em>Archaeopteryx</em> is iconic because it is a transitional fossil between non-avian dinosaurs (reptiles) and birds. The osteology of <em>Archaeopteryx</em> indicates that it was similar to that of nonavian theropod dinosaurs, i.e., dinosaurs characterized by hollow bones and three-toed limbs. Unlike modern birds, <em>Archaeopteryx</em> had a full set of teeth, a long tail, three fingers with claws and hyperextensible second toes commonly known as 'killing claws'.
Answer:
B. Fewer pesticides are needed because of parasitoids.
Explanation:
Herbicides are chemicals utilized to manage or command unwanted vegetation. Herbicide employment happens most commonly in row-crop cultivation, where they are employed before or throughout seeding to maximize yield productivity by decreasing other vegetation. Yields have improved considerably, and, in association with tillage, herbicide use decreases erosion, fuel usage, greenhouse gas discharges, and nutrient run-off, and preserves water.

DNA polymerase processivity and specificity decides that
Explanation:
The answer is C, Mercury.
Neptune and Uranus have extremely thick atmospheres, and Mars has an atmosphere that is made mostly of carbon dioxide, but Mercury doesn't have atmosphere at all.

The options are:
A) leaf abscission to prevent further loss
B) early flowering to try to reproduce before being eaten
C) production of chemical compounds for defense or to attract predators
D) production of physical defenses, such as thorns
Answer:
The correct answer of this question is- C) production of chemical compounds for defense or to attract predators
Explanation:
In response to attacks by herbivores, plants produce chemicals that are toxic to the herbivores which can even kill them or some chemicals can spread in the air and can attract the predators of those herbivores that attack that plant species.
Plants produce secondary metabolites that play an important role in protecting the plant from predators because they can be toxic and antimicrobial for example flavonoids, alkaloids, saponins. Plants do not get harmed by these metabolites because they have their own detoxification method. So the correct answer is C.
