intertidal zone
open ocean
neritic zone
transition zone
HELP
Answer:
c. neritic zone
A seabed or the ocean floor is the underwater structure that lies on the bottom of the ocean or sea. The oceanic floor comprises continental inclines and elevations, mid-ocean ridges, trenches etc.
The correct answer is:
Option C. Neritic zone.
This can be explained as:
The shallow region of the ocean is called the neritic zone that extends up to 660 feet of depths.The sunlight is available and plankton's and other organisms can make their food.It is the most prolific zone of the ocean because of the abundance of nutrients.Organisms like sea anemones, crabs, sponges, dolphins, jellyfish etc. prevail in this zone.Therefore, the neritic zone is the section of the ocean floor.

A population contains short plants and tall plants. The short plants are not able to compete with tall plants for sunlight. The tall plants, however, are more susceptible to wind damage. Which type of selection will this population of plants most likely experience? directional selection disruptive selection species selection stabilizing selection
Answer: D
Explanation: A population contains short plants and tall plants. The short plants are not able to compete with tall plants for sunlight. The tall plants, however, are more susceptible to wind damage.
Which type of selection are the plants experiencing?
directional selection
disruptive selection
If tall and small plants coexist in a population. Short plants are unable to compete for sunlight with tall plants. However, tall plants are more vulnerable to wind damage, it experiences stabilizing selection, hence option D is correct.
What is stabilizing selection?A form of natural selection when genetic diversity declines as a population stabilizes on a given trait value.
Disruptive selection's opposite is stabilizing selection. It favors the intermediate variants rather than people with extreme traits.
The more severe phenotypes are typically eliminated through stabilizing selection, which leads to the reproductive success of the average or typical phenotypes.
Therefore, stabilizing selection this population of plants most likely experience.

What is the role of tropomyosin in muscle contraction?
Answer:
Tropomyosin blocks myosin binding sights on acting molecules.
Explanation:
It prevents cross-bridge formation, which also prevents muscle contraction
Answer:The role of tropomyosin in muscle contraction is that it blocks myosin binding sites on acting molecules. Tropomyosin is a protein in the muscle contraction and prevents myosin from grabbing it,this prevents muscle contraction.When the nervous system contracts,calcium is released.

What species is our closest extinct relative?
Answer:
Neanderthals
Explanation:
They're our closest extinct human relatives, in comparison to Chimpanzees, as they're still alive...
Australopithecus afarensis species is our closest extinct relative.
Australopithecus afarensis is considered one of our closest extinct relatives. It is an ancient hominin species that lived between 3.9 and 2.9 million years ago. The most famous fossil example of Australopithecus afarensis is "Lucy," discovered in Ethiopia in 1974.
While Homo habilis, Homo neanderthalensis (Neanderthals), and Homo erectus are all part of the human evolutionary lineage and share common ancestry with us, Australopithecus afarensis is considered closer to the ancestral branch that eventually led to the Homo genus, which includes modern humans (Homo sapiens). Australopithecus afarensis displays key characteristics that link it to both earlier hominins and later species within the Homo genus.

blood vessels that contain valves and rely on skeletal muscles to move blood are called:
A) arterioles
B) veins
C) capillaries
D) arteries
and why!? thanks!!
Answer:
veins because they carry low pressured blood due to which there is more chance for backward flow of blood and to prevent that they contain valves.
hope it helped uh..
Answer:
B. Veins
Explanation:
Veins carry blood relying on the action of the skeletal muscle as the body moves. Veins have valves so blood flows in only one direction. Valves are not present in arteries. Arterioles is small and contains valves to prevent backflow of blood but does not rely on skeletal muscles. Capillaries don’t have any valves. The correct answer would be veins.
Who first identified nucleic acids, and where were they discovered? Friedrich Meischer discovered nucleic acids in blood cells. Phoebus Levine discovered nucleic acids in plant cells. James Watson and Francis Crick discovered nucleic acids in DNA. Gerardus Johannes Mulder discovered nucleic acids in bacterial cells.
Answer:
Friedrich Miescher discovered nucleic acids in blood cells.
Nuclein was discovered by Friedrich Miescher in 1869
Explanation
In the somewhat early 1880s Albert Kossel further purified the substance and discovered its highly acidic properties. Then he later discovered the nucleobases. In 1889 Richard Altman creates the term nucleic acid. Friedrich Miescher was the first scientist to ever isolate nucleic acid.
Friedrich Meischer was the first who discovered nucleic acids in blood cells. The correct option is A.
Who was Friedrich Meischer?Miescher, Johannes Friedrich, was indeed a Swiss physician and biologist. In 1869, he became the very first researcher to extract nucleic acid.
He also discovered protamine and managed to make several other discoveries.
In the winter of 1868 the adolescent Swiss physician Friedrich Miescher carried out experiments on the chemical composition of leukocytes in the research lab of Felix Hoppe-Seyler at the University of Tubingen, which resulted in the discovery of DNA.
Thus, the correct option is A.

Answer:Polar climate precipitation is the average temperature of the warmest month at less than 10 degrees celsius (50 degrees celsius).
Explanation:Polar climate regions are characterized by lack of warm summers.Polar climates tends to be extremely dry since the descending cold air does not have a significant amount of moisture.The two polar regions are usually identified as key regions for monitoring global change,because the surface air temperature and precipitation is expected to increase especially rapid in these two regions along with the ongoing increase of atmospheric carbon dioxide.
