Social sciences are the disciplines that study human social behaviour or institutions and the functions of human society in a scientific manner. So the correct option is D.
What is the importance of social science?
A collection or a group of disciples related to academic disciplines focusing on the behaviours of the individuals within society is called social science. It is the explanation of the working of the society which explores various aspects from economy to psychology.
The study of social science is relatively new in the field of scientific study. It gained popularity in the 20th century. Advertising, economics, psychology, teaching, managing etc are only some of the fields relied on social science.
The people who study social science are called social scientists. They rely more on the interpretation of the information and qualitative aspects of the methodology of methodologies.
The study of social sciences is important as they help in understanding the behaviour and motivations of the people in the world around us. It also helps in self-awareness.
Therefore the correct option is D.

What type of antenna where Penzias and Wilson testing in 1962 that led to their discovery of one of the biggest piece
of evidence supporting the Big Bang Theory
In 1964, Bell Labs scientists Arno Penzias and Robert A. Wilson were conducting experiments with the Holmdel Horn Antenna, an extremely sensitive device originally used to detect radio waves that were bounced off Echo balloon satellites, and later Telstar, the first active communications satellite. These radio waves were so weak, that it became critical to eliminate all possible interference in order to detect them.
Despite taking all conceivable steps to eliminate interference, they continually detected a strange, buzzing noise that was coming from all parts of the sky at all times of day and night. They did a range of additional testing on the equipment, and even removed some pigeons that were nesting in the antenna and their associate detritus. Still, the sound persisted. They ultimately determined that the noise was coming from outside of our galaxy
Almost by chance, they later learned that researchers and astrophysicists Robert H. Dicke, Jim Peebles and David Wilkinson at nearby Princeton University were looking for a way to detect residual radiation that they believed would have resulted from the Big Bang. As it turned out, the radiation detected by Penzias and Wilson was a perfect match for what the Princeton researchers had predicted, and hence made history.
Arno Penzias (left), Robert Wilson (center) and Keith Jefferts (right) look through a model of the universe to the constellation Orion where, for the first time, they discovered carbon monoxide in outer space.
From the archives
An audio recording of the CMBR noise was captured and narrated by Robert A. Wilson. This discovery in 1964 by Penzias and Wilson, announced in a Bell Labs press release, earned the researchers a Nobel Prize in Physics and provided the basis for future astronomical discoveries.

When the level of sugar in the blood is too high the excess sugar is stored in the
muscle to be used later as needed. Which characteristic of life is described here?
A. Ability to evolve
B. Use of energy
C. Maintaining an internal balance
D. Response to environment
Why are answer choice B is incorrect? Include in your response an explanation or
example of the incorrect choices. *
Your answer
Answer:
B
Explanation:
The characteristic of life is described in order to make reference that the glucose is stored in the muscle to be used later is MAINTAINING an internal balance (Option C).
Homeostasis refers to the functions of the body that work to maintain internal environmental conditions relatively constant.Insulin and glucagon are fundamental hormones that help to control sugar levels in the blood and thus maintain this homeostatic state.In muscle, glucose (sugar) is stored as glycogen.Glycogen is a polysaccharide composed of many subunits (monomers) of glucose.
In conclusion, the characteristic of life is described in order to make reference that the glucose is stored in the muscle to be used later is MAINTAINING an internal balance (Option C).

Science rejects any hypothesis not supported by __________________________ and the results of ___________________________ experiments. what are the blanks?
Answer:
Observations; control.
Explanation:
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.
On the other hand, a control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Hence, science rejects any hypothesis not supported by observations and the results of control experiments.
This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

Answer:
The carbon dioxide breathed out is a by-product of the process of cell respiration, as is water. In this process, energy is produced in the mitochondria of cells. ... When that reacts with oxygen (O2) in the cells, it produces carbon dioxide (CO2) and water (H2O). C6H12O6 plus 6O2 gives 6CO2 plus 6H2O plus energy.

Researchers propose a model to explain variation in phytoplankton cell sizes in a marine
environment. They base their model on the idea that smaller cells absorb nutrients more
efficiently. The researchers predict that the mean diameter of phytoplankton cells will
change by 50 micrometers for every 5-kilometer increase in distance from the shore
because of a gradual decrease in nutrient availability. To test their model, the researchers
determine that the phytoplankton cells found closest to shore have a mean diameter of
900 micrometers.
Based on the model, what will be the mean diameter of the phytoplankton cells that are
found 25 kilometers from shore?
Answer:
650 micrometers

Describe the structure of atoms,including the masses, electrical charges, and locations of protons, neutrons and electrons.
Everything on earth is made up of a fundamental particles that is impossible to see with the naked eye this particle is called the atom. There a over a 100 atoms or more in science. At the center of the atom is the nucleus which contains protons and neutrons. Electrons can be found moving around the orbitals or energy levels , while most of the area outside the nucleus is empty space .
Most of the mass of an atom is concentrated at the center of the nucleus.
Atoms are made up of three subatomic particles called
1. Protons
2. Neurons
3. Electrons
protons - has positively charge particles with a charge
of +1
Neutrons- has no charge it is neutral, 0 charge.
Electrons- has a negative charge particles with an charge of -1.
Relative mass of a particle is the mass compared to the mass of a proton
Relative charge of a particle is the charge compared to the charge on a proton.
Atom is a basic unit of matter have proton and neutron containing nucleus at the center and surrounding electrons.
What do you mean by atom ?
Atoms are the smallest and basic units of matter.
A negatively charged electron which surround the nucleus of the atom moving around the orbitals or energy levels.
The nucleus does not change during chemical reactions, only in nuclear reactions it will change.
In nucleus equal number of protons and neutrons, atomic number is the number of protons and atomic mass is made of the sum of protons and neutrons.
Relative mass of a matter is the mass of a proton while Relative charge of a matter is the charge on a proton.

Question 2 (2 points)
Which of the following best explains why matter must travel through cycles?
a
There is an unlimited amount of matter in the universe, so it can take on any form at
any time.
b
There is a fixed amount of matter in the universe, so it must take on different forms
at different times.
Elements flows within ecosystem in various ways. It is important for matter to travel through cycle as there is a fixed amount of matter in the universe, so needed to be recycled.
What is cycling of matter?Matter cycling is movement of matter from one form to another or from one place to another on the Earth, inside its ecosystems.
Matter is constantly cycling from place to place, and this can have both positive or negative effects. Matter also cycles naturally, or can be due to human activity.
As there are only finite number of nutrients on the Earth, so, it is necessary for them to be recycled in order to ensure the continued existence of living organisms.
