How did Newton map the orbits of the planets?
Answer:
Newton developed a mathematical formulation of gravity that explained both the motion of a falling apple and that of the planets. He showed that the gravitational force between any two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them
Explanation:
What conclusion can be drawn concerning an inhibitor if the Km is the same in the presence and absence of the inhibitor
Answer: The inhibitor has a structure that is not similar to the substrate.
Explanation:
Enzymes are molecules that act as catalysts of chemical reactions, accelerating the reaction rate without affecting the equilibrium of the reaction, as long as it is energetically possible. They act on molecules called substrates, which are converted into different molecules called products.
Enzymes are very selective with their substrates and are also susceptible to inhibitors which are molecules that regulate enzyme activity, inhibiting its activity. Inhibitors can be classified as reversible and irreversible. Irreversible inhibitors bind covalently to the enzyme with no possibility of reversing the modification they make, while reversible inhibitors bind reversibly to the enzyme and can reverse the modification.
A reaction occurring under the control of an enzyme reaches equilibrium much faster than the corresponding uncatalyzed reaction. The reaction, i.e. the production of products, can reach a saturation point if the substrate concentration increases too much, decreasing the concentration of free enzyme, which becomes the form with bound substrate. At the maximum rate (Vmax) of the enzyme, all active sites of the enzyme have substrate bound, and the amount of complexes is equal to the total amount of enzyme. The amount of substrate required to obtain a given reaction rate is also important and this parameter is given by the Michaelis-Menten constant (Km), which is the concentration of substrate required for an enzyme to reach half its maximum velocity. Each enzyme has a characteristic Km value for a given substrate, which can tell us how close the binding between the substrate and the enzyme is. Then, inhibitors bind to the substrate and increase the Km value as it interferes with the binding between substrate and enzyme. In this case, the Km value of the enzyme is the same in the presence and absence of the inhibitor, this means that there is no change, because the inhibitor has a different structure to the substrate, it does not bind and does not change the Km value.

One student made the incomplete diagram shown below to represent the relationship between magma igneous rocks and metamorphic rocks.
Which of these is the correct next step to complete the diagram?
A. Put an arrow labeled cools and crystallizes pointing from igneous rocks to metamorphic rocks
B. Put an arrow labeled cools and crystallizes pointing for metamorphic rocks to igneous rocks
C. Put an arrow labeled heat and pressure points in from igneous rocks to metamorphic rocks
D. Put an arrow labeled heat and pressure pointing from metamorphic rocks to igneous rocks
Answer:
C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks
Explanation:
Metamorphic rocks are changed rocks that are formed from pre-existing rocks that were once sedimentary or igneous rocks. Heat and pressure majorly act on igneous rock, which over time change these rocks into a different rock entirely, known as metamorphic rocks.
Therefore, the next step to complete the diagram will be:
"C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks."

Scientists have noted patterns in the Earth's seafloor structures. For example, volcanic ridges are typically located in the center of the oceans, and trenches are typically located along the edges of continents. In addition, seafloor rocks found at the trenches are usually older than seafloor rocks found at the volcanic ridges. Which explanation of the past movement of the Earth's plates is best supported by this information? A. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges. B. The continents were separated when new crust that formed at the edges of the continents pushed older crust towards the center of the ocean. C. The formation of new crust at the trenches widened the seafloor and pushed the edges of the continents away from one another. D. The Earth's crust formed at the trenches and moved towards the volcanic ridges to make room for newer crust, pushing the continents apart.
Answer:
A. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges.
Explanation:
The crust is divided into many plates that move over the mantle. Nowadays, there are six different bigger plates and twelve that are smaller. These plates are limited by three types of ridges or borders that differ in the movement they produce.
Boundaries types:
I. Divergent
II. Convergent
III. Transforming
In divergent boundaries, a new crust is created by the rising molten materials coming from the mantle. Two plates separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom. As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.

What would most likely occur over time if new technologies gave us information that challenged what scientists currently understand about natural selection
Question options:
A new scientific law would be established and proven by the findings. A new scientific theory would be established and proven by the findings. A current scientific law would be revised based on the new findings. A current scientific theory would be revised based on the new findings.
Answer:
A current scientific theory would be revised based on the new findings.
Explanation:
If new findings came about and challenged the current theory of natural selection so that Darwin's theory didn't look like it was true at all, the initial theory(darwin's theory of natural selection) would not be entirely discarded but revised according to these new findings and then form a sort of backbone to this new theory which would be based on findings of many independent researchers and not just one. Example: how some of Sigmund Freud's theories or Aristotle's may not be entirely valid today but still works as a fundamental for understanding other theories.

Answer:
Population Density
Explanation:
I had the same answer and it was correct
Make me brainliest pls
The term that is used to describe the number of deer in a square kilometer of forest is population density.
What is population density?
Population density is a measure of how crowded or dispersed a population is in a particular area. It is calculated as the number of individuals of a particular species per unit of area, such as square kilometer or square mile. This measure helps to understand the concentration of individuals of a species in a given area. A high population density means there are more individuals of a species per unit area, whereas a low population density indicates fewer individuals in a given area.
Population density plays a crucial role in understanding and predicting the effects of population growth on the environment. High population density can lead to increased competition for resources such as food, water, and shelter, which can cause stress on the ecosystem. It can also lead to an increased risk of diseases and higher rates of pollution. In contrast, low population densities can lead to the extinction of species due to lack of genetic diversity and inbreeding. Understanding population density is important for conservation biology, urban planning, and resource management, among others.

Describe the thickness of the uterus lining during
menstruation process.
Answer:
As the cycle progresses and moves towards ovulation, the endometrium grows thicker, up to about 11 mm. About 14 days into a person's cycle, hormones trigger the release of an egg. During this secretory phase, endometrial thickness is at its greatest and can reach 16 mm.
Explanation:
Answer:
During this timeframe, the uterus is in the proliferative phase. Estrogen induces growth of the functional layer of the endometrial lining, which enables it to grow from about 1-3 mm post cycle to 6-8 mm approximately. Days 12-16 of the menstrual cycle At this point, the endometrial layer is about 6-8 mm thick.

Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changingA) chemical energy into kinetic energy.B) chemical energy into potential energy.C) kinetic energy into potential energy.D) kinetic energy into chemical energy.E) kinetic energy into thermal energy.
Answer:
A
Explanation:
The correct answer would be that the sperms are changing chemical energy to kinetic energy.
In order to power the movement of the sperm cells, chemicals in the form of glucose molecules are hydrolyzed and the resulting energy from the reaction is used to power the movement of the sperm cells. Moving sperm cells possess kinetic energy. Thus, we can say that the chemical energy in the glucose molecules is converted to kinetic energy in the sperm cells.
