Answer:
B
Explanation:
Atoms connected by covalent bonds share electrons. Therefore, the correct answer is option B.
Extremely high ionization energies prevent some elements from accepting electrons, and extremely low electron affinities prevent some elements from accepting them. These elements' atoms frequently share their electrons with those of other elements or with other atoms of the same element in order for both atoms to achieve stability by forming an octet configuration in their respective valence shells. Covalent bonds are those associations that involve sharing electron pairs between entities of different or similar kinds.
Therefore, a pair of electrons is shared between atoms connected by a covalent bond. The correct answer is option b i.e. pairs of electrons.

While studying bacterial cells, scientists measure the lengths of the cells in one colony. The chart shows their data. The scientists notice that one measurement stands out. How should the scientists best deal with this measurement? accept it as true and use 85 micrometers in the data when they find the average length accept it as true but say that it is the only cell that has ever been that long consider that there was an error during measuring and collect further data consider that it is possible but very unlikely for these bacterial cells to be so long
Answer:
C
Explanation:
consider that there was an error during measuring and collect further data
Answer:
C .consider that there was an error during measuring and collect further data.

Why is water necessary for living things?
Answer:
To survive
Explanation:
Without water, we wouldn't have organisms such as fish. We also need it to break down food molecules or generate energy during the respiration process.
How do producers use the sun to get their energy?
Answer:
the answer is photosynthesis
Explanation:
Answer: Producers make their own food by photosynthesis, which is a process where plants get their energy from the sun and can make their food using the sun and rain. I hope this helps in some way!

How does the acidity of acid rain compare to the acidity of natural rainwater
Answer:
The acidity level of water is measured by the pH scale. Pure water has a pH of 7, which is neutral. However, natural rainwater actually has a pH of 5.6 because it gets exposed to the gases in the atmosphere, making it a bit acidic. True acid rain will have a pH level measuring from 5.0-5.5.

Can someone help me with these questions?
Answer:
1.32°F
2.212°F
Explanation:
1.The melting point is the temperature at which a solid turns to a liquid. The melting point at which ice — a solid — turns to water — a liquid — is 32°F (0°C).
2.Water boils at 212°F at sea level, but only at sea level. Changes in atmospheric pressure will alter the temperature at which water boils. To use this calculator you will need your current pressure and elevation.
3.In other words, the water molecules within ice move faster. However, temperature doesn't change as heat is added during a phase change; for example, when the ice melts. During the phase change, the added heat doesn't make the molecules move faster, but rather further apart.
Can you help me with the question listed in the pictures below? Please and thank you. Will mark BRAINLIEST!!! Answer choices Decrease or Increase
Answer: Decrease
Explanation: Because their foot is being used more.
I think that's what it said.
Fennec foxes (desert foxes) have ears up to 15 cm long. Thousands of years ago there was huge
variety in the size of the ears. Over time, those with the biggest ears were able to better survive as
they can lose more heat in the hot summer months. What would you expect to happen to the length
of Fennec fox ears if the temperature in the desert increases?
Answer:
You would expect their ears to also increase in size.
Explanation:
As the question says the ones with the biggest ears survived the best, implying if the temperatures rose the length of the ears would as well so that they could give off body heat.
All proteins have amino acids as their building blocks. Even though there are only 20 amino acids, there are more than a million different proteins, and each works in a unique way. Which of the following conclusions about a protein's function is best supported by this information? (4 points)
Group of answer choices
The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.
The amino acids reproduce in different ways, and this allows them to form many different proteins, which in turn directs the protein's function.
The shape of a protein determines what amino acids it is made of and what types of reactions it can be used for, which in turn affects the protein's function.
The shape of a protein dictates when a protein will break apart into amino acids, which in turn affects the protein's function.
Answer:
The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.
Explanation:
There are many different combinations for amino acids to bind, and all of the different combinations have very different structures.
Additionally, the unique shapes of all proteins determine the exact function that they have.
These different shapes will also affect what molecules can bind to it.
Which feature of nuclear fission reactions allows these reactions to take place in a chain reaction?
Thermal energy is released and heats up the reactants.
More smaller atoms form that can undergo fission.
A larger atom is formed, which can then be split.
Neutrons start the reaction and are released during it.
Answer:
Neutrons start the reaction and are released during it
Explanation:
N
Neutrons start the reaction and are released during it is the correct answer.
What is responsible for chain reaction?Neutrons start the reaction and are released during it is the feature of nuclear fission reactions that allows these reactions to take place in a chain reaction because the neutron that is released hit the other atom which leads to the start of other reaction and so on.
so we can conclude that Neutrons start the reaction and are released during it is the correct answer.

What would happen to a plant cell if it placed in water?
Answer: It really depends on if the water solution is hypotonic, hypertonic, or isotonic. If it is hypotonic (water with less salt or other dissolvent in it than the cell), you can expect the cell to take in water and expand. If the water is isotonic (about the same amount of dissolvent in it as the cell) just about nothing will happen, or if the water is hypertonic (more dissolvent in the water than the cell) the water can seep out of the cell, and into the water.

Scientists have developed a new herbicide for dandelions that is specifically designed to prevent the conversion of stored energy. Which process does this herbicide affect?
Answer:
Ability to make ATP or the release of oxygen from chloroplasts.
Explanation:
Given that, ATP which is an acronym for Adenosine triphosphate, is where the energy is stored and produced in a plant and at the same time Herbicides affect plants in the area of photosynthesis specifically affecting the release of oxygen from chloroplasts, which in turn prevents the generation of energy required for plant growth.
Hence, in this case, the new herbicides affect the ability to make ATP in plants or the release of oxygen from chloroplasts.

how are elements related to why different materials are used to make different products
Answer:The atoms of different elements are held together in compounds by chemical bonds. ... The properties of a compound depend not only on which atoms the compound contains, but also on how the atoms are arranged. Atoms of carbon and hydrogen, for example, can combine to form many thousands of different compounds.
What is the difference between smooth and rough endoplasmic reticulum (ER)?
The difference is that the the smooth (ER) is not bound by ribosomes. The rough endoplasmic reticulum on the other hand is bound by ribosomes.

M phase is known as mitotic phase and cell division occurs in this phase . The re-formation of the nuclear envelope during M-phase of the cell cycle takes place during telophase . The nuclear membrane which disappears during propahse reappears in the telophase . But before it is reformed the nucleus gets reorganised by Decondensation from chromosomes and reassembly of the nuclear lamina .MORE INFO :-______________
⚡ At telophase stage, nuclear membrane vesicles associate with the surface of individual chromosomes and fuse to reform the nuclear membranes, which partially enclose clusters of chromosomes before coalescing to reform the complete nuclear envelope .
