2) The diagram below represents a change in guard cells that open and close pores in a plant. Guard cell Open pore Closed pore This change directly helps to A) regulate water loss B absorb minerals C) increase heterotrophic nutrition D) reduce seed production
Answer:
A) regulate water loss
Explanation:
Guard cells refer to the cells enclosing each stomata. They assist in monitoring the rate of transpiration by closing and opening the stomata. The guard cells possess the tendency to monitor the closing and opening of stomata by changing shape. The shape of the guard cells modifies on the basis of the concentration of potassium ions and water found in the cells themselves.
The stomatal pores get closed when carbon dioxide is no longer needed for the process of photosynthesis. The guard cells swell when movement of water takes place inside these pores, and thus, the opening of stomatal pores occurs, and as water moves out, the guard cell closes. Thus, guard cells play an essential role in regulating water loss.

List 3 methods of fossilization and describe the process of each
Answer:
preservation of original remains- when the original remain is still in the rock/dirt, typically shells and bones.
permineralization- when the pores of plant materials, bones, and shells are impregnated by mineral matter from the ground, lakes, or oceans
molds and casts- casts preserve a three-dimensional impression of remains buried in sediment, the mineralized impression of the organism left in the sediment is called a mold.
replacement- form when water dissolves away dead tissue and leaves minerals in its place.
compression- a fossil preserved in sedimentary rock that has undergone physical compression
petrifaction- when the organic plant or animal material is replaced with minerals and eventually hardens into rock
compare and contrast - photosynthesis and cellular respriation

Q.19. During which period did the first flowering plants (angiosperms) appear?
a) Triassic
b) Silurian
C) Jurassic
d) Cretaceous
Answer:
Cretaceous
Explanation:
They began changing the way the world looked almost as soon as they appeared on Earth about 130 million years ago, during the Cretaceous period. That's relatively recent in geologic time: If all Earth's history were compressed into an hour, flowering plants would exist for only the last 90 seconds

Answer:
D
Explanation
As the river flow it will erode the side of the cutbank and deposit the sediments to the point bar.
how does the gravitational force between two objects change if the distance between the objects increases?
Answer:
YES
Explanation:
As g ∝ 1/d² between two two components, further potential difference would result in lower gravitational pull. So the influence of gravitational pull among them also reduces as two things are isolated from the others.
The ____ surface area exposed the ____ the weathering occurs.
A. Less, faster
B. More, slower
C. More, faster
D. Less, no change in rate
The more surface area exposed the faster the weathering occurs. Thus, the correct option is B.
What is Weathering?Weathering is the process of breaking down or dissolving of rocks and other mineral particles on the Earth's surface. Once a rock has been broken down into smaller pieces, a process known as erosion occurs which results into transport of the bits of rock and minerals away from each other. Water, acids, salt, plants, animals, and change in the temperature all are agents of weathering and erosion of particles.
Mineral weathering rates are directly proportional to the surface area of the minerals which are exposed to weathering. For example, if the rock is broken down into small pieces, it may undergo chemical weathering more readily than that of large pieces. This is because smaller pieces have more surface area for water and gases to react with the rock than the larger pieces of rocks.
Therefore, the correct option is B.
