Answer:
<em><u>D. The first flowering plants were introduced toward the end of the Mesozoic era.</u></em>
<em><u /></em>
Explanation:
Following the Paleozoic Era, the Mesozoic Era or <em>Age of Conifers</em> began approximately 250 million years ago. This major geological era brought about the ancestors of many of the plant and animal groups still in existence today.
The Mesozoic era is marked by 3 divisions:
- the Triassic Period,
- the Jurassic Period,
- and the Cretaceous Period.
Animals and plants slowly recovered after the mass extinction in the Permian-Triassic extinction that led to the eradication of most aquatic marine species. They evolved to exploit varying niches in their environment, leading to a boom in terrestrial animals. Over time the planet's increasingly warm climate, abundant in atmospheric oxygen and carbon dioxide, contributed to the growth of diverse megaflora, that rapidly dominated the planet's terrestrial biosphere.
By the end of the <em>Mesozoic Era</em>, in the Cretaceous period, flowering plants (angiosperms) largely replaced the dominant seed ferns of the <em>Triassic</em>, and the conifers, cycads and gymnosperms of the <em>Jurassic</em>.
<em>Varied dispersal mechanisms in angiosperms co-evolved with the evolution of certain types of fauna. Plants used animal life, including herbivorous reptiles and early mammal-like species to disperse large seeds.</em>
Autotroph is to producer as Hetrotroph is to consumer
Autotrophs make their own food, which makes them producers
While Hetrotrophs cannot make their own food, and must obtain it from another source, making them consumers
Hello. This question is incomplete. The full question is:
In 10th grade , Natalie fits the societal ideal of a slender body type . She is most likely a(n) :
A) late-maturer.
B) average-maturer.
C) prepubescent.
D) early-maturer.
Answer:
D) early-maturer.
Explanation:
If Natalie is in 10th grade, it means she is around 15-16 years old. This is an age when the body is being modeled after the molds of an adult body. However, children's characteristics should still be present at this age.
This is not what is happening to Natalie, since at this age she has a body that fits society's standards for a slim body. These standards of beauty in society are aimed at adult bodies, Natalie is not an adult, which shows that she is a person with early maturity.
Answer:
Photosynthesis: 6CO₂ + 6H₂O + solar energy ----> C₆H₁₂O₆ + 6O₂
Cellular Respiration: C₆H₁₂O₆ + 6O₂ ----> 6CO₂ + 6H₂O + ATP
Hope that helps.
