Answer:
Explanation:
Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation. Stomatal guard cells also regulate water loss of plants via transpiration to the atmosphere.
Answer:
regulate carbon dioxide and water input of a plant so the pant don't take in too much water or air

18. Intermediate fossil forms are important evidence
of evolution because they show
a. how organisms changed over time.
b. how animals behaved in their environments.
c. how the embryos of organisms develop.
d. molecular homologies.
Answer: Option A
How organism change over time
Explanation:
This is because intermediate fossils are form of fossils that are transitional because they are the transition change that occur between ancestral species and the descendents organisms. Therefore changes occur over time as organisms are been transited.
For example;
Amphibian or land vertebrate (Pederpes) have Intermediate form and it is transited between primary aquatic Upper Devonian amphibians
which is the anscestral and to early tetrapods which is the descendants.

Differentiate between Mesozoic era and Cenozoic era on the basis of time scale and origin of species.
Answer:
Explanation:
The Mesozoic Era is known as period of significant tectonicas well as climate, and evolutionary activity. It was known as as " Age of Dinosaurs or Reptiles" . During this era, the dominant form of life is dinosaurs.The Mesozoic Era come to life, arround 252.2 million years back. This Era can be sectioned into three different periods which are; ✓Triassic
✓Jurassic
✓Cretaceous
The span period of Cenozoic era was about 65 million years, this range from the end of the Cretaceous Period as well as the extinction of non-avian dinosaurs up to the present. Cenozoic era can be reffered to Age of Mammals such as (woolly rhinoceroses) this is because the largest land animals at this is mammals .The Cenozoic Era can be regarded as "new life" and it's known to be " age of mammals simply because largest animal that is available that time is mammals This era serves as the current as well most recent era among the three geological eras of the Phanerozoic Eon. The Cenozoic era has its spans of about 65 million years, and this range from towards end of the Cretaceous Period to the extinction of non-avian dinosaurs up to the present
The Cenozoic Era can be sectioned
into three periods which are;
✓ Paleogene : This is arround 66 million to 23 million years ago)
✓ Neogene : This is arround 23 million to 2.6 million years ago)
✓Quaternary; This is arround 2.6 million years ago to the present);

D
Two distantly related species both live in hot, dry deserts.
Answer: D. Two distantly related species both live in hot, dry deserts.
Explanation: Don't worry it's right. I know that for a fact because I just took the test.
The situation that would most likely lead to the development is : ( D )
Two distantly related species both live in hot, dry deserts ( D )Analogous structuresAnalogous structures are structures found in different species that appear to be similar and are also used for the same purpose in both species.
Analogous structures are not inherited from the same ancestor but are developed overtime to serve a certain purpose.
Hence we can conclude that The situation that would most likely lead to the development is Two distantly related species both live in hot, dry deserts.

How long has Earth been in its current era?
A. 1.8 million years
B. 65 million years
C. 5 billion years
D. 200,000 years
Science A P E X
The correct answer is B. 65 million years.
Earth has been in its current era, known as the Cenozoic Era, for approximately 65 million years.
The Cenozoic Era is the most recent geologic era and is characterized by the diversification and dominance of mammals, including the emergence of human beings. It is divided into three periods: the Paleogene, Neogene, and Quaternary.
The Cenozoic Era followed the Mesozoic Era, which ended with the mass extinction event that wiped out the dinosaurs.
The Cenozoic Era has witnessed significant geological, climatic, and biological changes, shaping the Earth's current state and providing the foundation for the development of modern ecosystems.

What can humanity affect about the amount of carbon in the ___? PLEASE HELP cycles of matter 19.1 study guide
Answer:
carbon cycle
Explanation:
A carbon cycle is a cycle that is defined as the continuous transfer of the carbon from the earth to the atmosphere and back to the earth form the atmosphere.
Humans affects the carbon cycle to a large extend by cutting down trees and burning the fossil fuels. The vehicles running on the road also releases large amount of carbon into the atmosphere. Large industries and factories are also one of major cause for the increase in the carbon level in the atmosphere. It all affects the carbon cycle as more and more carbon is released into the atmosphere and very less is absorbed back due to less trees.

Answer:
Phenotype ration of Green : other color plant will be 3:1
Genotype ration would be GG:Gg:gg
1:2:1
Explanation:
Let the dominant allele for green color of plant be G
Recessive allele for the above allele pair would be g let us say that "g" imparts black color
Then the genotype of two heterozygous green plants would be "Gg"
Gg * Gg
GG, Gg, Gg, gg
The three individuals of genotype GG, Gg, Gg will have green color
while the gg individual will have black color (as assumed)
Phenotype ration of Green : other color plant will be 3:1
Genotype ration would be GG:Gg:gg
1:2:1
