Answer:
the person above has correct
Explanation:
"Nebulae are made of dust and gases—mostly hydrogen and helium. ... Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star."

Amylase becomes denatured at a temperature of 80c. During an experiment to study the effect of varying temperatures on enzyme activity, amylase's reactivity with starch was measured at a body temperature of 37c and then again at an increased temperature of 42c. How would this increase in temperature affect the experiment?
Answer:
The rate of reaction will increase
Explanation:
Temperature is known to affect the rate of the reaction. Generally, chemical reactions depend on thermal activation. It means that an increase in temperature also increases the kinetic energy of the reactants. Increasing the temperature increases the reaction rate due to the increase in the number of molecular collisions between reactant molecules. The speed of a particle is directly related to its kinetic energy and thereby an increase in temperature also results in an increase in the amount of collisions between molecules per unit of time.

How is the egg transferred from the ovary to the uterus?
through muscle contractions
by using special hairs
by producing estrogen
through secretions of glands
Answer:
by using special hairs
Explanation:
When an egg pops out of an ovary, it enters the fallopian tube. Once the egg is in the fallopian tube, tiny hairs in the tube's lining help push it down the narrow passageway toward the uterus.
Answer:
B: By using special hairs.

explain how and why an earthquake occurs in thorough detail. You should also be identifying the four labels below within your explanation. A good answer would be longer than a paragraph (but < 3)
Answer:
An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.
Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!
Unfortunately brainly won't let me put the question for some reason, so I'll provide the question in the screenshot, please read...

compare the reproductive strategies of a short lived species such as a starfish and a long lived species such as a hippopotamus
Answer:
Starfish reproduce every winter by ejecting there eggs into the water, since they only live on average 35 years they reproduce about 35 times in their lifetime. Only a couple of the eggs will fertilize and turn into a Starfish.
Hippos are the only mammals in Africa that reproduce in water, Hippos reproduce in May and through June. Hippos usually live to around 40 to 50 years, and most hippos through May and June reproduce more than one time.
Explanation:
Hippos strategies of reproducing are better than Starfish.
Why is shoulder most susceptible ro joint dislocation?
Answer:
The muscles and ligaments around the shoulder tend to be stretchy and relatively vulnerable (compared to those around the hip). Thus the shoulder is relatively easy to dislocate. The hip is much harder to dislocate even though it is also a ball and socket joint.
Answer:
The shoulder's muscles are stretchey and like elastic in some ways, and then it is easy for someone to dislocate it.
Explanation:

Vertebrates are complex animals, but they still share some characteristics with invertebrates. Mia volunteers at her city's aquarium for the summer. She likes observing the invertebrates. Which statement explains the pattern in the body structures of invertebrates, starting with the sponges and ending with echinoderms?
Answer: Their body structure becomes increasingly more complex.
Explanation:
In the classification of living things, all animals belongs to Kingdom Animalia. This is contains two main groups namely:
--> invertebrates and
--> Vertebrates.
The vertebrates are complex animals which are characterized with the presence of a backbone.
The invertebrates are less complex animals with no backbone. The phyla that exists in this group includes: porifera, coelenterata, platyhelminthes, nematodes,annelida, mollusca, arthropoda,echinodermata and many among others.
Their body structure becomes increasingly more complex from the phylum porifera to the phylum echinodermata. The Sponges are simple aquatic invertebrates that have ASYMMETRICAL BODIES (this makes them to lack specialised tissues that could prevent them from moving about). While the echinodermata have RADIALLY SYMMETRICAL body with body parts arranged around a central mouth and anus. They have a unique system of water canals for transport inside the body and numerous tube feet moving about.

What does the term “carbon cycle” mean?
Answer:
Carbon cycle is:
the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

plate tectonics explains
Answer:
From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's surface in the present and the past. Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core.

Answer:
The sequence of the response of many living cells that produce energy during aerobic respiration. It occurs in mitochondria, consumes oxygen, produces carbon dioxide and water as waste products, and converts ADP into energy-rich ATP.
How is volvox life different than euglena life?
Answer:
Paramecium have cilia to move/eat, but euglena have flagella to move. How are euglena and volvox similar and different? Both can make their own food using chloroplasts (autotroph), but euglena can also hunt for their food. Both also use flagella to move, but volvox move together in colonies.
