Answer:
1. Inner, light-sensitive layer of the eye. Retina
2. Point where a muscle is attached to the more movable part. Insertion
3. Outer, fibrous layer of the eye. Sclera
4. Translates sound vibrations into nervous impulse. Cochlea
5. Prepares the body for activity. Sympathetic system
6. Sense of balance. Semicircular canals
7. Coordinates our muscular movements. Cerebellum
8. Point where the muscle is attached to the less movable bone. Origin
9. Active when the body is resting. Parasympathetic system
10. In the brain stem, controls the activity of internal organs. Medulla oblongata
Explanation:
The retina is the internal layer of the eye. It receives the light from the exterior and transforms these stimuli into nervous stimuli, which travels to the brain to give an image.The sclera is the outer layer of the eye. It protects the eye and keeps the eye's shape.A muscle has an origin and an insertion. The first one is the part attached to the less movable bone and the second one to the more movable part. These two parts can be in different bones. When the muscle contracts, the bone attached to the insertion moves towards the origin of the muscle.The cochlea and the semicircular canals are in the inner ear. The cochlea is the organ responsible for transforming the sound's vibrations into nerve impulses that will travel to the brain so that we can hear. In its interior, there are cells that have hairs, which move with the vibrations and transmit this message to the nervous system.The semicircular canals are three and with liquid that moves as we move. The movement of this liquid moves hair cells that are in the canals. These hair cells inform our brain about our location in space and give us a sense of valance.
The cerebellum is part of the central nervous system. It involves the coordination of movements, learning new movements, and controlling them.The sympathetic and parasympathetic nervous systems are part of the autonomic nervous system. The first one prepares our body for an emergency or an activity. It is the one that increases our respiratory frequency, our heart rate, dilates our pupils, makes us more alert, amongst other things. On the other hand, the parasympathetic system relaxes our body, slowing our heart rate, is involved in the digestion and the relaxation of our muscles. It activates, for example, after we eat.The medulla oblongata is part of the brainstem. It controls involuntary actions such as heart rate, respiration, and vasoconstriction. As it controls these functions, it affects internal organs like the heart, lungs, arteries, etc.

based on the reading above describe two diff between mysteceti and odonticeti whales one diff should be in anatomy and the other in feeding behavior. plz help me guys give a short answer
Answer:
both are different in feeding behaviour and blowholes.
Explanation:
The main difference between Mysteceti and odonticeti whales is the presence of feeding behaviour. Mysteceti whales also known as baleen whales which have baleen plates that capture prey from sea water while on the other hand, odonticeti whales have teeth which helps these whales to hunt aquatic animals. Baleen whales have baleen plates, or sheets, which sieve prey or food from seawater whereas toothed whales have teeth which helps them to actively hunt fish, squid and other sea creatures. The number of blowholes also different in both whales, Odontoceti whale has only 1 blowhole, but the Mysticeti has two blowholes in its body.

What is DNA replication? When and why does it occur?
Answer:
DNA replication is the biological process of producing two identical replicas of DNA from one orginal DNA molecule.
DNA replication occurs when the DNA strands unzip and the orginal strands of DNA serve as a template for new nucleotides to join and form a new strand. In needs to occur because existing cells divide to produce new cells.

How does composting help a landfill?
C. it allows things to decompose over 100's of years
B. helps break down biomass
D. it does not help the landfill
A. it takes up a lot of space
pls help :))
Answer:
C
Explanation:
It doesn't take 100s of years to decompose biomass. Usually it takes less than a year. Not C
It should help the land fill: D is incorrect
Initially it probably does take up a lot of space or more than the results of composting. But that's not why you do it. You do it because eventually very little will be left and it makes wonderful fertilizer. A is a half truth.

Explain 4 ways that invasive species are spread by humans?
Answer: They may be wind blown, rain splashed, carried by animals, or moved in soil or water. Almost all short-distance spread is through these natural dispersal mechanisms. In their home territory, short distance spread is rarely a problem because the resident plants and animals have evolved to coexist more or less peaceably.
Explanation:
Humans can help in the spread of invasive species.
What is an invasive species?It is a species that is not naturally present in an area ("not native") and when introduced in that area disturbs the ecosystem.For example, Eichhornia crassipes, cane toad, etc.How can human spread the invasive species?Humans can help in the spread of invasive species:
A species is introduced due to its beauty - because of its beautiful flowers and leaf shapes, the water hyacinth was brought to India.It is a contaminant of a species that is introduced - Parthenium is thought to have arrived in India as a contamination in PL 480 wheat from the United States.They may be brought accidentally- Zebra mussels arrived in North America's Great Lakes by accident, clinging to big ships.To control the population of other species - Small Indian mongooses were introduced with the goal of controlling rats that were ruining the sugarcane crop.To learn more about species, invasive species, population and ecosystem here,

1. What processes create igneous rocks?
2. What processes create metamorphic rocks?
3. What processes create sedimentary rocks?
Answer:
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
Sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
Explanation:
Answer:
1. Igneous rocks form when magma molten rocks cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.
2. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
3. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.

Relative to the length of time life has been on Earth, have modern humans appeared recently or in the distant past?
pLeAsE HeLp Me...
Answer:
recently
Explanation:
earth has had like for billions of years
humans have been here for hundreds of thousands
so to put it simply humans have been here for like 1/10000 of earths lifetime and that's very inaccurate but ik just making a point
In this exercise we have to explain why human beings are considered recent in relation to the time of the earth, so we can say that;
taking into account that the earth is 4.5 billion years old and human beings only existed for approximately 200 thousand years, we can say that we are extremely recent.
How old is a human being on Earth?Anatomically modern humans have their first fossil record in Africa, about 195,000 years ago, and molecular biology studies provide evidence that the approximate time of the common ancestral divergence of all modern human populations will have been 200,000 years ago.
