C. A gamete-producing fern plant is flat and shaped like a heart.
D. A mature spore-producing fern plant has fronds and produces
spores.
Answers
A zygote forms when a sperm fertilizes an egg cell does stage 4 show. So, the correct option is (B).
What is Zygote?After pollination, the male gametes present in the pollen grains move into the ovules and fuse with the female gametes where the single cell resulting from this fusion is called the zygote. This process is called fertilization.
In flowering plants, a haploid gamete called an egg cell and a sperm cell first fuse to form a diploid cell called a zygote. The zygote is the progenitor stem cell that gives rise to all embryonic and post-embryonic tissues and organs.
Thus, a zygote forms when a sperm fertilizes an egg cell does stage 4 show. So, the correct option is (B).

how do plants grow helppp

Answer:
During photosynthesis, plants take the water from the soil, and the carbon dioxide from the air, and they make sugars out of it. When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.

Answers
The chloroplast will only be found inside the Aloy plant while other structures will be shared by both cells. Option A is correct.
Difference between Plant and animal cells:Both plant cell animal cells are eukaryotic cells, but both have some unique structures.Plants have a cell wall but animals just have a cell membrane.A plant cell has a chloroplast for photosynthesis while an animal cell does not have a chloroplast.Since owl is an animal and Aloy is a plant
Therefore, the chloroplast will only be found inside the Aloy plant while other structures will be shared by both cells.

Which sediment would have the slowest rate of deposition?
a round sediment
O a very large sediment
an irregularly shaped sediment
O a high-density sediment
Answers
Answer:
C. An irregularly shaped sediment
Explanation:
Deposition is the settling of sediments within respective basins of deposition.
Irregularly shaped sediments are the slowest to settle within a basin this is due to the frictional resistance of their surface.
As these particles hits the water, the liquid drag on their edges is very great and prevents swift settling.
A. A high density sediment and a large sediment will have a fast settling time.
B. Rounded sediments will impose no friction on the water and they fall through the liquid very fast.
Answer:
the answer is C. an irregulary shaped sediment
Explanation:
