hi <3
there would be 2 electrons. each atom shares an electron each so in a single covalent bond, there would be 2 electrons
hope this helps :)
There are two electrons in a covalent bond.
Deeper meaning:-A covalent bond can be meant of as a 'shared pair' of electrons, so there are 2 electrons in each bond. This means that a double bond will have 4 electrons in the space between the bonded nuclei, and a triple bond will have 6.

what is semi conduction
Explanation:
Semi-conductive describes a component which conducts electricity less well than a good conductor but better than an insulator.
The hose should be semi-conductive, with a resistance high enough to insulate a stray current but conductive enough to get rid of static charge build-up.
Carbon black can be used to lower the resistivity of plastics, imparting antistatic, semi-conductive, or conductive properties.
Semi-conductive describes a component which conducts electricity less well than a good conductor but better than an insulator.

What are two characteristics of each of Earth’s four major systems?
Answer:
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air)
Describe the digestion of fats.
You should include reference to the following in your answer.
- Named regions of the alimentary canal and associated organs.
- Named chemicals, including the end producys of fat digestion.
Answer:
The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins. Your liver produces bile that helps you digest fats and certain vitamins.
Answer:
Triglycerides are large molecules, and unlike carbohydrates and proteins, they're not water-soluble. The digestive process has to break those large droplets of fat into smaller droplets and then enzymatically digest lipid molecules using enzymes called lipases. Digestion of fats mainly take place from fat enzymes produced in liver.

Which of the following mechanisms of change in genefrequencies is responsible for the antibiotic resistance of E. coli in this experiment?
A. founder effect
B. natural selection
C. population bottleneck
D. genetic drift
Natural selection is the mechanism responsible for the antibiotic resistance of E. coli.
Natural selection is a mechanism that favors the adaptation of organisms to survive in their environment, thrive and reproduce.
In the context of antibiotic resistance, antimicrobial substances exert selective pressure on microbes that encourages the evolution of resistance.
Those capable of resisting the effects of antibiotics survive and reproduce, while the vulnerable either die or have their growth inhibited.
The excessive and inappropriate use of antibiotics favors selection for antibiotic resistance in bacteria.
E. coli is characterized by having Gram negative bacilli, it represents the greatest risks of zoonotic transfer of resistance.
In general, and when a treatment is short, there is an elimination of sensitive saprophytic strains of E. Coli and an enormous predominance of resistant strains.
Bacteria also acquire antimicrobial resistance through vertical or horizontal transfer of genetic information.
Therefore, we can conclude that resistance to antibiotics in E. coli is due to the process of natural selection since it evolves to resist the action of an antimicrobial agent.

Match each part of a cell with the body part that has a similar function.
Nucleus
Cell membrane
Mitochondria
Cytoplasm
Answer:
Nucleus: blood
Cell Membrane: skin layer
Mitochondria; stomach
Cytoplasm: brain like structure
I'm not really sure of my answers.
Explanation:
The function of nucleus matches with that of brain and the function of cell membrane with that of Golgi bodies. Similarly, the function mitochondria is similar with that of liver and the function of cytoplasm is similar to that of skin.
What is a cell?
Cell is the basic unit of living bodies. A cell contains a nucleus, cell membrane, lysosomes, Golgi bodies etc.
Nucleus regulates all the functions of a cell as brain do in our body. Cell membrane helps to transport ions inside the cell as Golgi bodied do.
Mitochondria provide the energy and produce the chemicals needed for all chemical processes in the cell as liver do in our body.
Therefore, nucleus and brain matches in function and cell membrane and Golgi bodies matches in function. Similarly mitochondria and liver marches as well as cytoplasm and skin matches in functions.

A person lives on the Tropic of Capricorn. What is the altitude of Polaris?
O 23 1/2"
O 90°
O 66° 33"
O 15°
O 30°
O 45°
The correct answer as to what the altitude of Polaris would be for a person that lives on the Tropic of Capricon is 23° 1/2".
Polaris is a star and the altitude of any star is its height above the horizonThe Polaris is otherwise known as the North star as an indication that it is directly located overhead the north pole. Thus, it may not be visible once one moves South of the equator. The tropic of Capricon is located approximately 23° 1/2" South of the equator. In other words, the latitude of the Tropic of cancer is approximately 23° 1/2".Hence, the altitude of the Polaris at an altitude of 23° 1/2" will also be 23° 1/2", although it will most likely remain invisible.A person that lives on the Tropic of Capricon is approximately on latitude 23° 1/2". Since the altitude of a star is its height above the horizon, the altitude of Polaris from the Tropic of Capricon would, therefore, be 23° 1/2"

Due to the partial charges on atoms in a water molecule, ____ in water molecules are attracted to oxygen atoms in other water molecules.
Hydrogen bond in water molecules are attracted to oxygen atoms in other water molecules.
A hydrogen bond is a strong dipole-dipole attraction which occurs between:
the hydrogen atom attached to a strongly electronegative atom (for example oxygen in water molecules)another strongly electronegative atom with a lone pair of electronsHydrogen bonding occurs in the following compounds which include water, hydrogen fluoride and ammonia.
When an electronegative atom such as oxygen is bonded to hydrogen, a dipole develops causing the hydrogen to be partially positive while the other atom is partially negative.
Thus, this accounts for high boiling point in compounds that contains hydrogen bonds.

Viruses and bacteria can infect human cells. Bacteria are living organisms, while viruses are not. How do you think the treatment for viral and bacterial illnesses differ? How do you think they affect healthy body cells? Explain your response.
Answer:
hope it helps
Explanation:
1) antibiotic drugs can kill bacteria however, they are not effective against viruses
2) some bacteria's help to digest foods and speed up enzyme reactions. Some bacteria cells destroy disease causing cells
The treatment for viral and bacterial illnesses differs primarily due to the fundamental differences in their nature and characteristics. Bacteria are living organisms that can be targeted by antibiotics, whereas antiviral medications are used to treat viral infections.
Both bacteria and viruses can affect healthy body cells, with bacteria directly invading cells and causing damage, while viruses rely on host cells for replication and can induce damage during the process.
Bacteria and viruses can both cause damage to host cells. Bacteria can directly invade and damage cells through mechanisms such as releasing toxins or inducing inflammation.
Viruses require host cells to reproduce. They invade host cells, hijack cellular machinery to replicate themselves, and subsequently cause damage to the infected cells during the process.

Why do some scientists believe that RNA, rather than DNA, was the first genetic material?
RNA can replicate more accurately than DNA.
RNA contains uracil in place of thymine.
All of the protocells on early Earth contained RNA.
RNA has both information storage and catalytic properties.
The correct answer as to why some scientists believe that RNA, rather than DNA, was the first genetic material would be that RNA has both information storage and catalytic properties.
Other options are cannot be correct because:
RNA cannot replicate itself unless it is in a living host.RNA containing Uracil instead of Thymine has no effect on being the first genetic material or otherwise.There is no clear evidence to show that all of the protocells on early Earth contained RNAThe fact that RNA has the capacity to store information as well as catalyze important biological processes made it a plausible candidate as the first genetic material. DNA has the capacity to store information but lacks catalytic properties, unlike RNA.
