cause of the drop in the moss population?
Pine
Trees
Shrubs
Mass of Plants
Oak
Trees
Grasses
Mosses
Time
The formation of the climax community of the forest
Competition for light and resources with grasses
A lack of soil nutrients in the environment
Competition for light and resources with the oak tree
Answer:
Competition for light and resources with grasses
Explanation:
Mosses are small, flat brioftas that have no conductive vases, flowers, fruits and seeds. In a situation where a region has an intense density of trees as shown in the question above, mosses may be left with a limited amount of resources necessary for their survival, which will decrease their population. As a result, the moss will compete with other plant species.
In relation to the question above, the population of mosses would decline due to the competition for resources with grasses, this is because grasses have advantages in the absorption of resources, due to their biology.

When we look at stars, we notice that some appear brighter than others. Sirius looks much brighter than Rigel, but is it really brighter? Or is Sirius much closer to Earth, giving it the appearance of being brighter? Actually, Sirius is about one hundred times closer to Earth than Rigel. If the two stars were the same distance from Earth, Rigel would appear much brighter. -We use two terms to reference the brightness of a star: absolute magnitude and apparent magnitude. Absolute magnitude is the measure of the light given off by a star, while apparent magnitude refers to the amount of light received on Earth. The color of a star indicates its temperature. Blue-white stars are very hot, while orange-red stars are relatively cool. In the early 1900's Ejnar Hertzsprung and Henry Russell noticed that the higher the temperature of a star, the greater the star’s absolute magnitude. They developed a graph that depicts this relationship called the H-R diagram. Most known stars fit into a diagonal band that runs from the upper left to the lower right of the diagram. This diagonal band is called the main sequence. About 90% of all stars are main sequence stars. Most stars are currently classified using the letters O, B, A, F, G, K, and M, where O stars are the hottest and the letter sequence indicates successively cooler stars down to the coolest M class. Betelgeuse is in the red spectral class. It is one of the largest of stars with extremely high luminosity although it has a relatively low surface temperature. How would Betelgeuse be classified?
A. Giant
B. Supergiant
C. White Dwarf
D. Main Sequence

Number the steps (1-6) of Transcription to order the events in the correct sequence. (Worth 50 points)
____ The DNA “rezips,” reforming the original complementary cross-strand
bonds
____ The DNA and messenger RNA strands separate from one another and the
RNA leaves the nucleus
____ Helicase “unzips” the DNA-RNA hybrid
____ RNA polymerase joins the new RNA nucleotides into a single strand
____ Helicase “unzips” the DNA, opening the two strands of the double helix
____ Free RNA nucleotides make complementary pairs between their own
nitrogenous bases and the attached bases of the single DNA template
strand.
Answer:
6, 5, 4, 2, 1, 3
Explanation:
Transcription refers to the process of the formation of RNA molecules from DNA molecules using DNA strands as a template.
Only one strand out of two DNA strands is involved in the process and the strand is known as coding strand which runs in the direction of 5' to 3'.
The process of transcription takes place in the following sequence:
1. Helicase enzyme binds to the DNA and unzips the two strands of DNA. This opens the helices of the DNA and the DNA gets open.
2. RNA polymerase binds to the promoter attached to the DNA and forms the single strand.
3. The RNA nucleotides form complementary base pairs with the DNA and the RNA strand. A new complementary strand is made using complementary base pairing.
4. DNA helicase unzips the DNA and RNA hybrid.
5. The DNA and RNA get separated and the mRNA molecule formed in the nucleus exits the nucleus.
6. The two-strand of DNA is again joined via complementary base-pairing rule.

Answer:
Yes, it does.

Habitat destruction is one of the main reasons species go extinct. If they have no place to live and be safe in their habitat, they're left in the open available to any predators ready for a meal.
What can scientists infer about the period of very early Earth from the fossilized remains of trees found under a lake?
Answer:There is a theory that terrestrial plants evolved from aquatic plants through a process of natural selection. Thus, by finding fossils of plants under the river, scientists may conclude that this theory is correct and that these fossils represent the ancestors of terrestrial plants.
The emergence of plants that survive on earth is a very important milestone for the planet, it is believed that these plants have evolved from green algae called Chlorophyta that have survived in marshy areas that had alternating periods of flooding and drought.Then the discovery of these fossils, through scientific experiments may conclude that the theory is correct
Explanation:
Answer:
The fossil record is the record of life on earth preserved in rock as fossils. The fossil record provides evidence of where types of plants and animals lived, how long they lived, how they died, and how they changed. It also tells us about Earth’s early environment and how it changed. The fossil record helps determine the age of rock formations by looking at how deep the fossils are buried in the rock. When a fossil is found above another fossil in a rock formation, the deeper fossil are considered older.

What is the speed of a wave with a frequency of 6oHz and a wavelength of 20m
Answer:
speed = 1200 m/s
Explanation:
given data
frequency = 60 Hz
wavelength = 20 m
solution
we get here speed of a wave that is express as
speed = Frequency × wavelength ...............................1
put here value and we get speed
speed = 60 × 20
speed = 1200
so speed of a wave is 1200 m/s
