Answer 1

Answer:

Explanation:

There are five columns here; electronic configuration (electron distribution), number of shells, valence electrons (number of electrons on the outermost shell that can participate in bond formation), period number (on the periodic table) and group number (on the periodic table).

Aluminium-13 (₁₃Al)

This means Aluminium has 13 electrons and thus will have the properties below

Electronic configuration: 1s²2s²2p⁶3s²3s¹

Number of shells: From the electronic configuration written above, Aluminium-13 has 3 shells.

Valence electrons: The number of valence electrons (as seen in the electronic configuration - for the third shell) is 3.

Period number: Aluminium is found in period 3 because it has 3 electron shells

Group number: Aluminium is found in group IIIA because it has 3 electrons in it's outermost shell.

Calcium-20 (₂₀Ca)

This calcium atom has 20 electrons and thus have the following properties.

Electronic configuration: 1s²2s²2p⁶3s²3p⁶4s²

Number of shells: As seen in the electronic configuration above, calcium-20 has 4 electron shells.

Valence electrons: As seen in the electronic configuration also, the total number of electrons/valence electrons in the outermost shell is 2.

Period number: Calcium-20 is found in period 4 of the periodic table because it has four electron shells.

Group number: Calcium-20 is found in Group IIA of the periodic table because it has 2 electrons in it's outermost shell

Tin-50 (₅₀Sn)

This tin atom has 50 electrons and hence have the following properties

Electronic configuration: [Kr] 4d¹⁰5s²5p²

Where [Kr] is the electronic configuration of krypton atom

Number of electron shell: From the electronic configuration above, Tin-50 has 5 electron shells

Number of valence electrons: From the electronic configuration also, it has 4 valence electrons.

Period number: It is found in period 5 because it has 5 electron shells

Group number It is found in Group IVA because it has 4 electrons in it's outermost shell

Barium-56 (₅₆Ba)

Electronic configuration: [Xe] 6s²

Number of shells: 6

Number of valence electrons: 2

Period number: Period 6

Group number: Group IIA

Selenium-34 (₃₄Se)

Electronic configuration: [Ar] 3d¹⁰4s²4p⁴

Number of shells: 4

Number of valence electrons: 6

Period number: Period 4

Group number: Group VIA

A student designs an experiment to see if detergent affects the growth of seeds. He sets up 10 seed pots. Five of the seed pots will receive a small amount of detergent in the soil and will be placed in the shade. The other five seed pots will not receive detergent and will be placed in the sun. All 10 seed pots will receive the same amount of water, the same number of seeds, and the same type of seeds. He allows the seeds to grow for two months and charts their growth every two days. What is wrong with his experiment

What causes the Pacific Ring of Fire to have so many volcanoes?

Answers

The abundance of volcanoes and earthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area. Along much of the Ring of Fire, plates overlap at convergent boundaries called subduction zones. That is, the plate that is underneath is pushed down, or subducted, by the plate above. As rock is subducted, it melts and becomes magma. The abundance of magma so near to Earth’s surface gives rise to conditions ripe for volcanic activity. A significant exception is the border between the Pacific and North American Plates. This stretch of the Ring of Fire is a transform boundary, where plates move sideways past one another. This type of boundary generates a large number of earthquakes as tension in Earth’s crust builds up and is released.

Two different species mate and produce a zygote. As it starts to develop, it dies due to the genetic differences. What would this be called

Answers

Answer:

Postzygotic barrier

Explanation:

The reason why the species died due to genetic difference or genetic variation after the species produced zygote and begins to develop was because of what is called POSTZYGOTIC BARRIER.

POSTZYGOTIC BARRIER is a barrier or otherwise obstacles that does not allow offspring that are fertile and capable of producing a specie to form by preventing the formation after the species has begin to develop which is the development stage thereby making the already formed species to die.

Explain the role of a hypothesis in a scientific investigation.
Answer:

Short answer please quick

Answers

Answer:

A hypothesis is a testable proposition

used to explain scientific phenomena. It

may be based on previous observations

(a sort of educated guess) or it may

simply be a hunch. Most scientific

hypotheses are combinations of

observation and intuition. The important

thing is that the hypothesis be testable.

If the hypothesis is disproved through

testing, then it is discarded and a new

hypothesis is proposed. If the hypothesis

stands up to rigorous testing, then our

faith in the hypothesis is increased.

This system of careful, rigorous, and

unbiased testing of a hypothesis is what

characterizes the scientific method.

This evolutionary tree shows the influence of speciation and extinction on the diversity of life. After 2 million years, lineage A had a(n) ________ rate of extinction and ________ speciation rates compared to lineage B.

Answers

Answer:

Lower; higher

Explanation: Speciation is a term used to describe the formation of new, distinct and diverse set of characters and organism as evolution occurs in lineages of an organism.

The higher the number of lineages the higher the number of diverse characters and features. That is what makes the speciation to be lower in the chances of extinction to be higher as the lineages Increase from lineage 1 to lineage 2.

Answers

Answer:

Mitochondria.

Reactants of cellular respiration are glucose and oxygen.

Explanation:

Mitochondria is the location of cellular respiration where glucose is broken down in the presence of oxygen into energy in the form of ATP. When a glucose molecule is broken down with the help of oxygen, it produces energy, carbondioxide gas which is a waste material and water. There are three products of cellular respiration such as energy, carbondioxide and water. Energy is used by the organism in different activities while carbondioxide gas and water are removed from body through breathing. Using of glucose by mitochondria and converted into energy in the form of ATP is the energy flow.

Division of prokaryotes is not called mitosis .why?

Answers

Answer:

gagvd

Explanation:

fuurryou

shhyuhgf

Answer:

The DNA of prokaryotes is not enclosed within a membrane, and is instead localized to a region called the nucleoid. This DNA acts as the prokaryote’s only chromosome, so the process of DNA replication is much quicker. After DNA replication, the original chromosome and its copy seperate. A cleavage furrow forms between the cell, the cell eventually pinches in half, and two identical daughter cells, each with an identical chromosome, are formed.

Provide a scientific explanation on how a mutation to the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein.

Answers

Answer:

Change in DNA leads to change in the structure of the cell.

Explanation:

Mutation in the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein because mutation is the sudden change that occur in the genes of a cell which change the genetic makeup of the cell. So when change occur in the DNA, a sickle cell is formed instead of normal hemoglobin. Normal hemoglobin only formed when the no change occur in the nitrogen base of DNA.
