Answer:
Yes, it does.
Explanation:
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.

Explanation:
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

How does disease affect blood pressure
Explanation:
The body has lots of mechanisms that can control the blood pressure, plus, changing the amount of blood the heart pumps, the diameter of the arteries, and volume of blood in the bloodstream. When a disease causes blood pressure to stay high, low, or in between, problems can arise.
In Kingdom Animalia, there are is a wide variety of organisms such as humans, reptiles, fish, birds, insects, and mammals. These organisms are different from each other in many ways. Why would scientists classify all of these organisms into the same Kingdom?
All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups.

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

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.
