A.
Muscle cells have a large volume of cytoplasm so that the cell can easily change shape.

B.
Muscle cells contain a large number of mitochondria in order to provide more energy.

C.
Muscle cells do not have nuclei because they do not need to produce proteins.

D.
Muscle cells are surrounded by cell walls so that they are strong enough to move bones.

Answers

Answer:

is B

Explanation:

it isnt C or D so let's look at A and B so the answer is more likely going to be B because A your muscles cant change shape and C your muscles are protien and D humans and animals do not have cell walls that only have cell membrane

Answer:

No B. is incorrect, the REAL answer is actually C.

Explanation:

The main function of muscles is to move body parts by contracting, which requires a lot of energy. so C. is the only answer that concludes with this. The cell structure that produces energy is the mitochondrion.

Therefore, the best prediction is that muscle cells contain a large number of mitochondria in order to provide more energy.

So that means B. would be an assumable answer.

Identify the number of valence electrons in each atom:
a. Calcium
b. Carbon
c. Sulfur

Answers

Answer:

-Sulfur is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S₈. Elemental sulfur is a bright yellow, crystalline solid at room temperature.

(Atomic number: 16

Electron configuration: [Ne] 3s²3p⁴

Electrons per shell: 2,8,6

Electronegativity: 2.58)

-Calcium is the 20th element, with 20 protons. Since a stable atom has a net charge of 0, we must have 20 electrons.

-Carbon is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust.

(Symbol: C

Atomic mass: 12.0107 u

Atomic number: 6

Electrons per shell: 2, 4

Electron configuration: [He] 2s22p2

Electronegativity: 2.55)

According to the electronic configuration, number of valence electrons in each atom of calcium,carbon and sulfur is 2, 4 and 6 respectively.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

() pls help meeeeeeeeeee if right i will give brainiest i promise You are a financial advisor helping a young family create a college fund to provide for their daughter Marys education. Mary just turned 5. Her parents expect that she will go to Harvard University, starting school on her 18th birthday. She will only take four years to complete her degree. Currently, tuition and housing costs total $65,000 per year, which are paid at the beginning of each school year. These expenses are expected to increase at the rate of inflation which will run 4% annually for the next 25 years. In each year until Mary enters Harvard University, Marys parents will make a deposit into the college fund to exactly provide for all of the costs of her education when she enters college (the first deposit will be made one year from today). Since her parents expect their income to grow at the rate of 2% annually, they would like the amount that they put each year into the fund to increase in nominal terms at the rate of 2% annually. Marys parents can earn a rate of 10% annually on their investments and they face a 30% tax rate. A. What do you expect tuition and housing to cost during Marys first year at Harvard University?B. How much must be in the savings account on Marys 18th birthday after the last deposit has been made but before the first payment to Harvard University?C.
