Answer:
D. Stem cells are often extracted from human embryos.
Explanation:
This is a major point of ethical concern and is also a root for many abortion conspiracy theories. The reason it is an ethical concern is because harvesting stem cells often times kills the embryo.

Bacteria convert the nitrogen in the atmosphere into
a.Usable nitrogen
b.Non-usable nitrogen
Answer:
b. Usable nitrogen
Explanation:
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.

What will most likely occur if population density increases in a population that is density dependent?
Birthrate will decrease.
Carrying capacity will increase.
Death rate will decrease.
Immigration will increase.
Answer:
D
Explanation:
Population density is the number of individuals in a unit square area. As if population density increases in a population that is density-dependent, will increase immigration, i.e., option D.
What is immigration?Immigration is a process by which individuals become residents of another country permanently.
The process of immigration is of great importance for social, economic, and culture of states.
As population density increases in a population that is density-dependent immigration will also increase.
Thus, the correct option is D.

For this assignment, you will ask questions about the factors that have caused a rise in global
temperatures over the past century. Then, you will conduct research to answer your questions. You will
also graph provided information, analyze the graphs, and make conclusions based on the graphs. Finally,
you will write a paper describing the conclusions of your research and graphs.
Background Information
Global temperature change is a gradual increase in the overall temperature of the Earth's atmosphere.
Both human activity and natural processes have contributed to this temperature increase. Examples of
human activities include the burning of fossil fuels, cement production, and agricultural activity. Examples
of natural processes include changes in incoming solar radiation and volcanic activity.
Scientists present evidence for the rise in global temperature in the form of tables, graphs, maps, and
models. For example, scientists build climate models (computer simulations of climate systems) to
explore the causes and effects of global temperature change and to predict future trends. These models
predict that the Earth’s average surface temperature will rise as greenhouse gas concentrations continue
to rise. Based on these models, scientists predict that average surface temperatures could rise by
between 2°C and 6°C by the end of the 21st century.

On a warm day near the ocean, a breeze or wind often blows from the water to the land. Explain why this happens
Answer:
It occurs because of the difference in temperature between the ocean and the land.
This happens because the land heats up faster than the water, causing the air to rise above the land and allowing cooler air from the ocean to move in and take its place.
What is sea breeze?Because land and water have different capacities for holding heat, the land will heat up more quickly than the water on a hot day near the ocean. As a direct consequence of this, the air that floats above land tends to become warmer and less dense than the air that floats above water. Because of this, a region of low pressure is created over the land, while a region of high pressure is created over the water. In order to maintain a natural equilibrium, air will always move from areas of higher pressure to areas of lower pressure.
A breeze or wind that blows from the water to the land is caused by the air that is cooler and denser over the water moving towards the air that is warmer and less dense over the land. This phenomenon, which is referred to as a sea breeze, can assist in moderating temperatures on land, thereby making it feel more bearable and pleasant to be there.

it is to do with something called angular moment. Gravity is the central force in the Universe, because it is the only one which has a significant pull over large distances.
5:Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. ... These forces of inertia and gravity have to be perfectly balanced for an orbit to happen.
6;Gravity is the force that keeps planets in orbit around the Sun.

Scientists sink concrete blocks in oceans to create artificial coral reefs. Which successive event most likely occurs first on this type of coral reef
Answer:P
Explanation:got it right
Coral polyps attach themselves to the surface to grow is the event most likely occurs first on this type of coral reef.
What is Coral reef?Coral reefs are significant ocean habitats that make a strong argument for the dangers of climate change. Reefs are a significant contributor to the biodiversity of the planet; they have been referred to as "the rain forests of the seas." One of the most diverse environments on earth, coral reefs are home to 25 percent of all marine species, according to scientists.
According to Paulo Maurin, coordinator of education and fellowships for NOAA's Coral Reef Conservation Program, the reefs are essential to the biodiversity of our world.
Many fish species use them as fruitful nurseries, giving the young fish a place to live and an opportunity to develop, according to him. "The diversity of coral reefs is so great that we don't have a firm count of all the species that live there,"
Therefore, Coral polyps attach themselves to the surface to grow is the event most likely occurs first on this type of coral reef.

A cladogram is shown below. What is a derived characteristic that distinguishes the salamander from the perch? lungs claws or nails fur jaws
About the question:
You will a cladogram in the attached files.
Answer:
lungs
Explanation:
A Cladogram is a tree-type graph based on cladistic analysis. It represents the common ancestral relationships among the involved groups.
• The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.
• The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes. It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.
• The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.
So the cladogram represents the relationship between groups according to a derived character.
The derived character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.
A cladogram provides an image of how new species keep characters that were inherited from older species.
In the attached cladogram, you can see that the lungs are the derived character that distinguishes the salamander from the perch.
Claws or nails separate salamander from lizards.
Fur separates birds and reptiles from mammals.
Jaws separate hagfish from perch.
Mutations occurred in evolution producing new traits, and these traits also appear in posterior groups. So, after the hagfishes emerged the jaws, and all the animals that followed the hagfishes have jaws.
Lungs appeared after the perch and before salamander, so salamander, and all the posterior animals, have lungs. And so on.

The idea that the brain of an infant is like a blank slate is known as: ____
a- tabula rasa
b-dry cup
c-cogito ergo sum
d-the empty brain
Answer:
a
Explanation:
The idea that the brain of an infant is like a blank slate is known as Tabula rasa. It is given in Locke's philosophy. Thus, the correct option is A.
What is Tabula rasa?Tabula rasa is the theory which describes that individuals are born without a built-in mental content, and therefore all the knowledge comes from experience or perception in life. The epistemological proponents of the tabula rasa disagree with the doctrine of innatism, that holds the fact that the mind is born already in possession of certain knowledge eithout experience.
In Locke's philosophy, tabula rasa was the theory that at birth the infant mind is a blank slate without rules for processing data, and the data is added and rules for processing are formed solely by one's sensory experiences in life.
Therefore, the correct option is A.
