hi i need your help guys! Using the periodic table, fill in the following table with the number of electrons in each energy level of the element given.
n = 1 level n = 2 level n = 3 level n = 4 level
Element (maximum 2) (maximum 8) (maximum 18) -----------
Carbon- ________ ________ ________ _______
Answers
i think its
carbon- 2 (there are two in the n=1 level) 4 (there are four in the n=2 level)
i might be wrong, but hope this helps :)
Electrons in atoms are arranged in energy levels. The electrons in the energy levels of carbon are;
n= 1 ------ 2 electrons
n = 2 ----- 4 electrons
n =3 ----- 0 electrons
n = 4 ----- 0 electrons
Carbon has the electronic configuration; 1s2 2s2 2p2.
This means that there are only two electrons in the n-1 level and there are four electrons in the n=2 level.
This makes a total of six electrons in carbon as shown.

Answers
Answer:
Prophase I, metaphase I, anaphase I and telophase I.
Explanation:
Prophase I is the phase of meiosis I in which DNA condenses to form chromosomes whereas in metaphase I, each pair of chromosomes lines up in the center of the cell. In anaphase I, each pair of chromosomes is separated from one another which is pulled by the spindle to opposite poles of the cell. In telophase I, the duplicated genetic material is separated that leads to two identical daughter cells.
How do autotrophs and heterotrophs benefit one another within an ecosystem?
A. Autotrophs produce oxygen and carbon dioxide for heterotrophs, which produce chemical energy for autotrophs.
B. Autotrophs synthesize ATP and other nutrients for heterotrophs, which produce oxygen for autotrophs.
C. Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.
D. Autotrophs transform chemical energy into radiant energy for heterotrophs, which fix carbon for autotrophs.
Answers
Answer: The answer is A,
Explanation:
Answer:
C. Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.
Explanation:
Autotrophs are organisms that conduct photosynthesis. One of the products of photosynthesis is oxygen, which is released into the air. Heterotrophs then take in this oxygen and give out carbon, which then the plants take in and use. This cycle goes endlessly on and on.

The strangler fig is a vine that starts out as a seed in the tree canopy of the rain forest. It drops its roots down from the canopy to the forest floor. By sprouting in the rain-forest canopy, the strangler fig seedling is exposed to more-
The strangler fig plant shows an aggressive growth habit as an adaptation that allowed its growth. It drops to the forest floor and develops its seeds by exposure to sunlight. Thus, option A is correct.
What are adaptations?Adaptations are a crucial part of the evolutionary process that allows the organism to fit and survive in altered environmental conditions. It has been due to the process of natural selection that gets inherited.
The aggressive growth habit of the strangler fig vine is to ensure its survival in the rainforest covered in canopies. The seed of the plants uses sunlight and nutrients to grow at a faster rate and hangs their roots on the first floor. The sunlight increases its rate of germination.
Therefore, option A. sunlight is used for germinating the fig seeds.

Cellulase enzyme is needed for the breakdown of cellulose molecule.
The bacteria present in the digestive system of cow produces cellulase which is a very important enzyme responsible for the breakdown of cellulose. This cellulase enzyme attached to the cellulose molecules and speed up the breakdown which results in the production of glucose molecules.
This glucose is further used by the cell for the generation of energy which is used in different activities. Glucose is the monomer from which cellulose is formed. The cellulase enzyme detached from the cellulose molecule after the completion of the chemical reaction so we can conclude that cellulase enzyme is needed for the breakdown of cellulose molecule.

What is the central nervous system?The brain and spinal cord make up the central nervous system. The brain directs our thoughts, memories, movements, and emotions. Between the brain and the nerves that run throughout the body, the spinal cord relays messages.
It regulates cognition, personality, memory, emotion, speech, and the capacity to feel and move. The corpus callosum, a band of nerve fibers in the middle of the brain, connects the left and right hemispheres of the brain.
Thus, the central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.

During the third trimester of pregnancy, the fetus grows in size and weight. So option B is correct.
What features of the baby develop during the third trimester?During the first trimester, the zygote develops into a moving fetus which has working organs such as eyes and ears. In the second trimester, the features of the baby are developed and the movement of the baby can be felt. In the third trimester, the fetus grows in size and weight.
The third trimester starts from the 27th week and continues until the end of the pregnancy. The lungs of the baby are still developing. At the end of the third trimester, the length of the fetus is 19-21 inches and the weight is about 6-9 pounds. In the end, the baby will gain more weight and is prepared for delivery.

A strong acid has a pH approaching:

A strong acid has a pH of 0.
This is because strong acids generally have a pH of 0-3, and if you check the pH scale the higher you go up the scale, the less the pH will be, therefore less acidic. 7 is generally the neutral mark and anything past that is a weak alkali.
