There are several different types of cells in our body including bone, cartilage, blood, muscle, and nerve cells. Regardless of the type of cell they all have the same ___ [ Select ] ___ but different ___ [ Select ] ___
Answer:
This question is incomplete
Explanation:
This question is incomplete and hence makes it difficult to be accurate because of the absence of options. However, for the first blank space, what human cells have in common (with each other in the same body) is the genetic composition thus it can be said that regardless of the the type of cells, almost all of them have the same DNA or genes. However, presence of the same DNA does not mean they carry out the same function. This is as a result of a process known as differentiation.

What name is given to a factor which is preventing any increase in photosynthesis?
Answer: A limiting factor
Explanation: A limiting factor is simply anything in short supply that prevents photosynthesis occurring at its maximum rate. Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.
Any factor that prevents any increase in photosynthesis is known as a LIMITING FACTOR.
In photosynthesis, a limiting factor is defined as a factor/agent that constrains photosynthetic activity.The most important factors capable of limiting the rate of photosynthesis include light, carbon dioxide (CO2) level and temperature.For example, photosynthesis cannot take place without light, which is absorbed by chlorophyll pigment molecules to start photosynthesis.In conclusion, any factor that prevents any increase in photosynthesis is known as a LIMITING FACTOR.

What best explains how they should complete the table?
with “Inside the nucleus,” because the particle is a proton
with “Inside the nucleus,” because the particle is a neutron
with “Outside the nucleus,” because the particle is a proton
with “Outside the nucleus,” because the particle is an electron
Explanation:
Protons and neutrons are subatomic particles found in the atom of any substance.
These particles collectively determines the mass number of the atom.
Protons are positively charged particles found in the nucleus of an atom. Neutrons do not carry any charges and are also found in the nucleus. Electrons are negatively charged particles.Electrons occupy the extranuclear space of an atom.
Answer:
Depends, you have to give us a table, let me explain how to answer this.
Explanation:
“Inside the nucleus,” because the particle is a proton
For this to be true, it has to have a mass (amu) of 1 and it has to have a positive charge
“Inside the nucleus,” because the particle is a neutron
For this to be true, it has to have a mass (amu) of 1 and it has to have a neutral charge
“Outside the nucleus,” because the particle is a proton
This is instantly wrong because protons are located in the nucleus
“Outside the nucleus,” because the particle is an electron
For this to be true, it has to have a mass (amu) of 1/2000 and it has to have a negative charge
Greenhouse gases are measured by their ability to trap outgoing solar radiation and convert it to heat, warming the atmosphere.
Global warming potential is defined as the ability of an atmospheric gas to contribute to increasing global temperatures and
anthropogenic climate change. Carbon dioxide is used as a baseline for global warming potential, with a GWP of 1. What best
explains why CFCs (chlorofluorocarbons) have a GWP
nearly 5000?
Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.
This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.
Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

1.
Helium
Hydrogen
Nitrogen
2.
Hydrogen
Lithium
Helium
3.
Copper
Silver
Iron
Answer:
1: hydrogen
2: helium
3: iron
Explanation:
In medium-sized stars such as the Sun, nuclear fusion almost always means the fusing of hydrogen nuclei to form helium, but larger stars can produce elements as heavy as iron. The correct options are B, C, and C.
What is Nuclear fusion?The primary distinction between these two processes is that fission is the splitting of an atom into two or more smaller ones whereas fusion is the fusing of two or more smaller atoms into a larger one.
In nature, fission reactions are uncommon. Many highly radioactive particles are created during fission.
The Sun and other stars are powered by nuclear fusion reactions. In a fusion reaction, two light nuclei fuse to form a single heavy nucleus. The process releases energy because the overall mass of the resulting single nucleus is less than the mass of the two initial nuclei.
Therefore, the correct options for 1, 2, and 3 are B, C, and C, respectively.

Which equation best represents conservation of matter? (1 point)
3H2O + 3CO2 → C6H12O6 + 602
6H2O + 6CO2 + C3H603 + 302
6H2O + 6CO2 → CH12O6 + 602
6H2O + 10CO2 → C5H12O6 + 402
i’m so sorry for asking so many questions!
Conservation of matter is the law that states the amount of matter involved and produced. The reaction, 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂ follows the law. Thus, option C is correct.
What is conservation of matter?Conservation of matter has been the law used in science that defines the amount or the mass of the matter to remain the same even after undergoing a chemical reaction where the reactant yield product.
In some cases, the matter seems to be lost but in reality, it is due to the change in the phase of matter. So, the mass in a system is a constant that is neither added nor removed.
The equation, 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂ best represents the law of conservation as there are 12 hydrogens, 6 carbon, and 18 oxygen on both sides of the reaction.
Therefore, option C. 6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂ follows the law of conservation of mass.

Why are plants important to the carbon water and nitrogen cycles?
Answer:
The carbon and water cycle I know, but I can't help with the nitrogen cycle. Sorry.
Explanation:
Carbon cycle - The role that plants play in the carbon cycle is that they take in our carbon dioxide and put out oxygen, which we breathe. So we give the plant air and they give us air.
Water cycle - The role that plants play in the water cycle is when it rains, the plants absorb some of the water in their roots, thus making them strong and therefore helping the ground not become a mud hole.
Sorry that I can't help with the nitrogen cycle. But I hope what I was able to help you with helps!

Explanation:
Universe kept expanding is an inaccurate statement on the diagram.
What is big bang theory?The most popular theory for how the universe came into being is called the Big Bang Theory. Simply expressed, it states that the universe as we now understand it originated from an unimaginably hot and dense single point and expanded over the course of 13.7 billion years, initially at unfathomable speeds and subsequently at a more palpable pace.
The universe's expansion, cosmic microwave background radiation, abundances of the lightest chemical elements, age of the earliest known stars, and abundances of these elements are some of the major evidences for the big bang idea.
