Atoms can be seen with the naked eye. C. All atoms are the same. D. Atoms make up every substance around you.
Answer:
Atoms make up every substance around you.
You cannot see single atoms without a special microscope. But every substance around you is made of atoms.
Explanation:
Atoms make up every substance around you is the true statement. Therefore, option (D) is correct.
What are atoms?An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids.
Moreover, at the most basic level, all organisms are made of a combination of elements. They contain atoms that combine together to form molecules. In multicellular organisms, such as animals, molecules can interact to form cells that combine to form tissues, which make up organs.
Every day, our bodies take in new atoms from the air we breathe, the food we eat, and the liquids we drink. These atoms are incorporated into our cells and fuel the chemical processes that keep us alive.

Our solar system is made up of the Sun and the astronomical bodies that orbit it. But you may be surprised to learn
that all the planets and nearly every asteroid in the solar system orbit the Sun in the same plane and in the same
direction. They all move counterclockwise, if viewed from above Earth's North Pole. What do you think caused this
phenomenon?
Answer:
Hey there!
This can be explained using the conservation of angular momentum, which the planets get attracted to the sun because of its large size, and massive gravitational pull.
Let me know if this helps, or if you need a further explanation :)
The cause of the phenomenon leading to the clockwise movement of the planets in the same direction would be:
- 'Conservation of Angular Momentum'
Solar SystemThe various planets and asteroids present in the solar system function in the same path and direction.
The key reason behind this is the 'angular momentum' which leads them to rotate in a linear manner.
The conservation of this constant angular momentum allows these bodies to conserve the very same path along with direction due to their size and gravitational energy.

Explanation:
What are the key features of life? Select all that apply. Organisms acquire energy and nutrients through consumption of other organisms. Organisms sense and respond to changes in their environment. Organisms are composed of one or more cells. Life is sustained by inputs of energy and nutrients. Genetic information in the form of DNA is passed to offspring.
Answer:
Organisms sense and respond to changes in their environment.
Organisms are composed of one or more cells.
Life is sustained by inputs of energy and nutrients.
Genetic information in the form of DNA is passed to offspring.
Explanation:
Not all organisms acquire energy by consuming other organisms. Most green plants, for example, are able to produce their own food by photosynthesis.
Organisms are able to sense and respond to changes in their environment. Without these, survival would be limited. Plants are able to sense and respond to light, water, gravity, etc. while animals are able to sense dangers and run away from them.
According to the cell theory, all living organisms are made up of cells. The simplest organism must contain, at least, a cell, while more complex organisms are made up of several cells.
Life is generally sustained by the input of energy from the sun and that of nutrients from reservoirs such as soil. Plants are able to manufacture their foods by using the energy from the sun and other animals either depend directly or indirectly on plants for their own energy. Important nutrients are cycled from their reservoirs to living organisms and vice versa.
Genetic information in the form of DNA is passed from one generation to another during reproduction. Reproduction is an important attribute of living organisms and it remains the only way life is sustained on the planet.
explain the 1st and 2nd law of thermodynamics in terms of food chain, energy flow, pyramid of number and pyramid of energy
Answer:
First law of thermodynamics is the conservation of energy states that energy is not created and not destroyed but only can be stored.
Thermodynamics second law states that total entropy of a system increases from lower to higher system and some of the energy is always wasted during the work done.
In the food chain plants are the producers which accept light energy and stored in the form of chemical energy and energy flow to the herbivores and higher trophic levels in the chemical form only and no new energy is created in between the chain (Fisrt law of thermodynamics). Heat is generated during respiration by plants and animals (wasted energy) and entropy also increases with the increase in level of the pyramid of energy (Second law of thermodynamics).

What are the characteristics of a scientific question
Answer:
A scientific question is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation. Asking a scientific question is a part of the scientific method (which includes making an observation, asking the question, forming a hypothesis, testing it and accepting/rejecting/modifying the hypothesis). A good scientific question has certain characteristics. It should have some answers (real answers), should be testable (i.e. can be tested by someone through an experiment or measurements), leads to a hypothesis that is falsifiable (means it should generate a hypothesis that can be shown to fail), etc. For example, an observation that a passing car makes a lot of noise can prompt someone to ask "if there is some correlation between the speed of the car and the noise it generates", which can result in a hypothesis that at higher speeds more noise is generated. This can be tested by driving a car and measuring the noise level and these results can help us accept or reject or modify the hypothesis.
Explanation:
Which stage is repeated as many times as necessary? * 5 points research analyze and conlcude observe and ask questions test your hypothesis
Answer:
the analyze and conclude stage
Explanation:
In research, this stage involves carefulness. The researcher needs to perform analyze the results of his experiment to see whether they agree with his initial hypothesis. If necessary, that is, if the results are not in agreement with the hypothesis they will have to create a new hypothesis and then perform another analysis and conclusion.
A blow to the cheek is most likely to break which superficial bone or bone part? (a) superciliary arches, (b) mastoid process, (c) zygomatic arch, (d) ramus of the mandible
Answer:
The correct answer is option c, that is, zygomatic arch.
Explanation:
In anatomy, a section of the skull produced by the temporal bone’s zygomatic process and the zygomatic bone’s temporal process is known as the cheekbone or the zygomatic arch. Temporal bone refers to a bone, which protrudes frontward from the skull side, that is, over the opening of the ear, while the zygomatic bone is the lateral to the cheekbone.
When a blow takes place to the cheek then the superficial bone or the part of the bone that breaks most likely is the zygomatic arch.

Water molecules are polar. Explain the distribution of charge in a molecule of water.
Answer:
Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge (Delta-) near the oxygen atom due the unshared pairs of electrons, and partial positive charges (Delta-) near the hydrogen atom.Water molecules are polar because it determines the bent shape of the molecule in which the partial negatively charged atoms are covalently bounded to the partial positively charged hydrogen atoms.
What are the other characteristics of water molecules?The other characteristics of water molecules are as follows:
It acts as a universal solvent.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.The distribution of charge is determined by the fact that the oxygen atom attracts electrons a bit more strongly than the hydrogen atom. This is due to the unequal sharing of electrons between the two different atoms.
This unequal sharing of electrons is responsible for obtaining a slight negative charge near the oxygen atom, while a slight positive charge near the hydrogen atom.
Therefore, it is well described above.

correct. The scientist is unhappy, but studies the new evidence anyway. The scientist is showing which
scientific attitude?
a creativity
b. curiosity
open-mindedness
d. skepticism
Answer:
C- open-mindedness
Explanation:
I say open-mindedness because an open minded type of person will accept advice although they may not agree and looks over to see maybe if there is something they may have missed. A curious person doesn't really fit his description in my opinion. Neither does a creativity type of attitude. Last, skepticism means you just basically are not about to even consider doubting yourself and you just know your right without a doubt.

DNA Ligase is responsible for: A. adding the new bases. B. keeping the strands separated during replication. C. linking the short sections of the lagging side. D. unwinding and separating the DNA strands.
☯️ The DNA ligase is responsible for :
Linking the short sections of the lagging side.Explanation:-The ligase is a enzyme responsible for the linking or joining of short sections or strands. It connects the strands by forming a bond between the phosphate group of one DNA strand with deoxyribose group of other.
It is also used in Okazaki fragments connection which are formed in the lagging side during DNA replication. So, We can say that DNA ligase is a specific enzyme which helps in the linking and connecting the DNA strands or fragments by the formation of phospodiester bond[tex].[/tex]
