In the Table of Elements, which SUBATOMIC particle of an Atom affects the arrangement of elements? *



Science

Answers

Answer:

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.

Which of the following explains why an apple looks red? The apple reflects red light and absorbs all other visible wavelengths. The apple absorbs red light, and reflects all other colors of light.. The apple is absorbs all visible wavelengths, but absorbs red light better The apple is reflects all light that hits its surface.​

Answers

Answer:

The apple reflects red light and absorbs all other visible wavelengths

Explanation:

The apple is only reflecting the color red and is absorbing the other colors of light (wavelengths)

The correct explanation why an apple looks red is that the apple reflects red light and absorbs all the other visible wavelengths. Thus, the correct option is A.

What is Absorption and reflection of light?

Light absorption is the process in which the light ray is absorbed by the matter and converted into a form of energy. In an atom, the electrons vibrate at a specific frequency, then this is called as the natural frequency.

Reflection is a phenomenon of light. When a ray of light approaches a smooth polished surface such as metal and the light ray bounces back, it is called the reflection of light. The incident light ray which land on the surface is reflected off from the surface. The light ray that bounces back is called the reflected ray.

Therefore, the correct option is A.

if a child had O type blood and the mother had B type blood and the father had A type blood, could a blood test eliminate the father

Answers

Answer:

No, a blood test could not eliminate the father.

Explanation:

The mother had B type blood, so the possible genotypes are BB and BI.  The father had A type blood, so the possible genotypes are AA and AI.  The child had O type blood, so the only possible genotype is II.  If the mother has the genotype BI and the father has the genotype AI, then there is a 25% chance the child will have the blood type O, or II (I used a punnet square with the genotypes BI and AI to solve this.)

if you wanted to eliminate wind what would be the best way to do it

Answers

Answer:

The best way to eliminate the wind is to build barriers.

Explanation:

As you may already know, the wind is a large-scale flow of gases. This flow is palpable and can be prevented from entering certain places by building physical barriers that block the flow. In this case, the construction of barriers prevents the wind from advancing and reaches a certain region, because it causes the wind to crash against this barrier and be pushed back, prevented from advancing.

Answers

Answer: A scientific theory concerns nature and is supported by data collected through field observations and experiments.

Explanation:

Scientific theories are only established based on verified facts derived well organized research and experiments using data and other supporting evidences. Theories differ from hypothesis or philosophical sayings which lacks factual and reproducible evidences.

Mrs. Underwoods theory could best be deemed as an assertion because her theory lacks an established and reproducible evidence prepared from data or experimental research to back up or align with her theory.

how can patterns be used to identify common ancestry?

Answers

Answer:

5

Explanation:

4

......"...................."

By comparing and contrasting morphological or genetic traits of an organism, patterns can be used to determine its common ancestry. When species exhibit comparable traits, it shows that those traits were inherited from a common ancestor. On the other hand, when organisms exhibit different characteristics, it implies that they diverged from a common ancestor and evolved separately.

What are patterns used in common ancestry?

In genetics, common ancestry can be determined using patterns in DNA sequences or protein structures. A high degree of similarity between the DNA or protein sequences of two or more species indicates a tight relationship and a more recent common ancestor.

In contrast, different DNA or protein sequences within species indicate a more distant common ancestor and a more distant relationship between them. Scientists can reconstruct the evolutionary history of many animals and find patterns of common ancestry by comparing the DNA sequences of those organisms.

Therefore, by comparing and contrasting morphological or genetic traits of an organism, patterns can be used to determine its common ancestry.

What are the Amino acids of the mutated DNA sequence: TAC ATC TTG GCG ACG ACT

Answers

Answer:

Tyr Ile Leu Ala Thr Thr

Explanation:

In a DNA sequence, a pair of three bases form a codon that codes one particular amino acid in the protein. Proteins are consist of  20 amino acids and these amino acids are coded by a pair of three bases.  

There are four bases in a DNA - Thymine (T), Adenine(A), Guanine(G) and Cytosine(C).

The given mutated DNA sequence will also code for some amino acid, that is as follows:

TAC - Tyr (Tyrosine)

ATC - Ile (Isoleucine)

TTG -  Leu (Leucine)

GCG - Ala (Alanine)

ACG - Thr (Threonine)

ACT - Thr (Threonine)

Thus, The mutated DNA sequence  TAC ATC TTG GCG ACG ACT codes for Tyr Ile Leu Ala Thr Thr.
