Explanation:
Answer: From birth to three years old they produce 700 neural connections. A baby has 100 billion neurons. It multiplies to trillions at two years old, most probably at three it would be quadrillions.
Explanation: Babies are born with billions of brain cells, and by the time they are three years old, they have formed trillions of brain connections. This rapid increase in brain connections is a result of the brain's remarkable ability to adapt and change in response to experiences. As babies interact with their environment, engage in play, and receive nurturing and stimulating experiences, their brain cells form new connections, creating a complex network of neural pathways. The exact number of brain connections varies between individuals, but it is estimated that by the age of three, a baby's brain can have trillions of connections. These connections are essential for cognitive development, learning, and the foundation of future abilities and skills.

The_____(lysosome, ribosome ,nucleus)
gets rid of cell waste by breaking down large molecules into smaller ones for the cell to excrete. The____(Golgi apparatus,cell membrane, endoplasmic reticulum)
helps these waste molecules exit the cell.
Answer: Lysosome, Cell Membrane
Explanation: Lysosomes are little sacs in the cell that latch onto waste materials and break them down (I've found an easy way to remember this is to remember that the root "lys" means "to split" or "to break down"). As for the second part, the Cell Membrane is the outermost layer of the cell, and is responsible for allowing things in and out of the cell.

which correctly shows the transfer of energy within an ecosystem?
A. producer, decomposer, herbivore omnivore
B.carnivore, herbivore, decomposer, omnivore
C. omnivore, carnivore, herbivore, primary consumer
D. producer, herbivore, carnivore, decomposer
producer, herbivore, carnivore, decomposer (option D).
The correct sequence showcasing the transfer of energy within an ecosystem is producer, herbivore, carnivore, decomposer. The cycle begins with producers who are eaten by herbivores. These herbivores in turn are eaten by carnivores. Lastly, decomposers break down all the dead or waste materials, returning nutrients back to the ecosystem.
Explanation:The correct order that shows the transfer of energy within an ecosystem is producer, herbivore, carnivore, decomposer (option D). The cycle initiates with producers like plants or phytoplankton, which convert light energy into useful forms via photosynthesis or chemosynthesis. These producers, forming the base of the ecosystem, are consumed by herbivores, termed as primary consumers. Secondary consumers, often carnivores, feed on these primary consumers. Lastly, decomposers, such as fungi and bacteria, break down all the dead organisms or waste materials from each trophic level, recycling nutrients back into the ecosystem.

The movement of tectonic plates in two locations is described below: 1) Location A Tectonic plates push together. 2) Tectonic plates pull apart. Which statement is most likely true? A) ocean basins May form in both locations. B) volcanic eruptions May occur in both locations. C) ocean basins May form in location A but not in location B. D) volcanic eruptions May occur in location B but not in location A.
Answer:
The answer is D.
Explanation:
Plates which pull apart are known as divergent plate boundaries, while plates which push together are known as convergent plate boundaries. At divergent plate boundaries, magma flows up from the inner parts of the earth and flows out. When it cools and turns to stone, types of volcanoes are left. Magma is stored inside the volcanoes.

A skeletal muscle is a composition of several components bundled one into the other. At which structural level in the muscle does contraction occur
to bring about contraction in the whole muscle?
Answer:
The correct answer will be- myofilamants-actin and myosin.
Explanation:
The skeletal muscle is made up of the muscle fibers which are cylindrical cells enclosed by layers. The muscle cell is divided into smaller units, the smallest of which is myofilaments.
The myofilaments are composed of the thin filaments called actin and thick filaments called myosin which together forms the functional unit of a muscle known as the sarcomere. The muscle contraction takes place due to the sliding of these actin and myosin over each other as a result of the signals arrived from the CNS.
Thus, myofilaments-actin and myosin is the correct answer.
Which atmospheric layer prevents meteoroids from reaching Earth's surface?
mesosphere
stratosphere
thermosphere
troposphere
Answer:
mesosphere layer - first choice
Answer: Option B. "Mesosphere"
Explanation:
Atmospheric layer that prevents meteoroids from reaching Earth's surface is mesosphere.
The mesosphere is the highest layer of the atmosphere and above the stratosphere. In the mesosphere layer, the air relatively mixed together in this layer and the temperature decreases along with the altitude and most of the meteors burn up in the mesosphere.
Thus the correct option is mesosphere.

At higher elevations, the boiling point of water decreases, due to the decrease in atmospheric pressure. As a result, what could be
said about hard boiling an egg?
a. At higher elevations, it would take less time to hard boil an egg, because there is less atmospheric
pressure.
b. At higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point,
the egg is boiling in water at a lower temperature.
c. At higher elevations, it would take less time to hard boil an egg, because there is a lower boiling point
Therefore it would take less time to achieve the boiling point.
d. At higher elevations, it would take longer to hard boil an egg, because it would take longer to achieve
the boiling point
b. At higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point, the egg is boiling in water at a lower temperature. The correct answer is that at higher elevations, it takes longer to hard boil an egg because the water boils at a lower temperature due to reduced atmospheric pressure.
At higher elevations, the boiling point of water decreases due to the decrease in atmospheric pressure. When hard boiling an egg, this means that the water will boil at a lower temperature, so the correct answer is: b. At higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point, the egg is boiling in water at a lower temperature.
The interaction between atmospheric pressure and boiling point is such that as pressure decreases, the boiling point also decreases. This means that at higher elevations where the pressure is lower, water does not reach as high a temperature when it boils compared to sea level, which implies that cooking an egg thoroughly will require more time as the temperature at which energy is transferred to the egg is lower.
Which best describes the outcome of DNA replication? The new DNA molecule consists of one strand of DNA. The new DNA molecule accumulates a new strand of DNA with each replication. The new DNA molecule consists of one new strand and one old strand of DNA. The new DNA molecule contains new DNA, and the old molecule keeps the old DNA.
Answer:
The new DNA molecule consists of one new strand and one old strand of DNA
Answer:
The correct answer is the third statement.
Explanation:
The replication of DNA refers to a biological phenomenon, which produces two similar molecules of DNA that are the replicas of the original molecule of DNA. The double-stranded DNA gets distinguished into two template strands. Each of the template strand functions as a guiding strand for generating a counterpart known as a complementary strand.
The complementary and the template strands attach with each other to produce a new double-stranded DNA. Thus, the new molecule of DNA comprises one new strand (complementary strand) and one old strand (template strand) of DNA.

Which would be an adaptation in a rain forest, but not in a desert?
A. Ability to store water for a long time
B. Better eyes for hunting prey
C. Skin that blends in with green plants
D. Very small leaves to trap water
ANSWER:
The correct option is C: Skin that blends with green plants. Most animals in rain forests are green so that they can camouflage and appear like plants.
EXPLANATION:
Adaptation is the way in which animals survive in different climatic conditions and different regions. In rain forests, to protect themselves and to find food, most animals are green in colour. This prevents the animals from being spotted easily and therefore they are protected from hunters and other animals that eat them. This way, the animals can also find their prey and catch it easily.Answer: c <3

Disturbances inside Earth’s core cause earthquakes. The starting point of the disturbance is called the epicenter. Why does the amplitude of a seismic wave usually decrease as the wave moves away from the epicenter?
Answer:
The energy released by the earthquake spreads throughout a larger volume of Earth.
Explanation:
At farther distances the amplitude of the seismic waves decreases as the energy released by the earthquake spreads throughout a larger volume of Earth. Also with increasing distance from the earthquake, the waves are separated apart in time and dispersed because P, S, and surface waves travel at different speeds.

Explanation:
This stage of bacteria causing disease is known as Lytic cycle ,in this cycle phage 1st binds to the receptor present on the surface of the bacterial cell. Then the phage injects its DNA into the host cell and then protein synthesis and DNA coping occurs. The capsid proteins are stuffed with DNA to make lots of new phages particles.
Figure 17-3 shows smaller and larger beaks in a population of finches. One group of birds has a short, parrot-like beak and another group has a long, narrow beak. What process has probably occurred?
Answer:
Natural selection has occured, and through evolution, the finches have evolved to adapt to their surroundings.
Answer:
disruptive selection
Explanation:
The question above shows a situation resulting from the disruptive selection process.
Disruptive selection is a type of natural selection that allows individuals with more extreme characteristics to be favored by the environment and end up having a better chance of surviving and generating descendants. Individuals with intermediate characteristics end up being disadvantaged and have less chance of survival.
In relation to the question above, we can say that the short-beaked birds will have greater facilities in breaking seeds and therefore will be favored. Long-billed birds will find it easier to reach worms for food. On the other hand, medium-billed birds (intermediate characteristics) will be less favored both in hunting worms and in breaking hard seeds.
