In the given case, falling of earplugs while visiting a loud factory could result in the damage to the middle ear.
How the middle ear can damage?Rupture in the eardrum, that is, a thin tissue, which separates the ear canal from the middle ear can cause damage in the middle ear. The middle ear damage can lead to hearing loss. Rupture in the eardrum can also make the middle ear susceptible to infections.
Middle ear damage can result due to:
Otitis media or middle ear infectionStress imparted on the eardrum Sudden loud sound or blast from a very loud factory or gunshotSevere head traumaTherefore, in the given case, due to fall-out of earplugs of Kelli while visiting a very loud factory could result in damage to the middle ear.

You want to determine if black coat color (B) and long tail length (T) are linked in a new breed of dog (white coat and short tails are recessive). Design a two-point test cross to determine if this is indeed the case. What results would you expect if the genes were linked
Answer:
If the genes were linked, the phenotypic and genotypic ratios would be different from 1:1:1:1. The observed proportions in the F1 would be different than the expected ones if genes would assort independently.

how is mitosis different in plants and animals
answers
A. in animals, the cell membrane pinches together.
B. in plants, the dna is one circular chromosome
C. in plants, there are no sister chromatids.
D. in animals, a new cell wall forms
Answer:
a
Explanation:
In animal cells, the cell can simply split apart and the membrane will form on its own while with plant cells in order to split it must first form a cell plate that will later become a cell wall.

which is a reason cells divide?
A. to prevent tumor formation
B. to have a smaller surface area
C. to reproduce
D. to stop binary fission
Answer:
C. to reproduce
Explanation:
All living cells undergo division to produce more identical or different cells. The major types of cell divisions that cells undergo are; mitosis and meiosis. Mitosis results in two identical daughter cells being produced from a single cell while meiosis results in four daughter cells being produced.
The primary aim of any form of cell division is to REPRODUCE or PROCREATE the number of cells. For example, mitosis produces two (2) cells from 1 and so on....

Carbon-14 is a radioactive isotope of carbon that has a half-life of about 5,730
years. You have discovered a fossil and want to know how old the fossil is. You count
the parent and daughter atoms and calculate that you have about 6.25% of the
parent atom (carbon-14) left. How old is the fossil? (Provide units (years) for your
final answer. You must show your work.
2 points for showing work
1 point for final answer with units
Answer:
22,920 years
Explanation:
When the fossil first started to decay, it must have had 100% of its parent carbon-14 atoms. Every 5,730 years, that amount gets cut in half. Let's travel back a ways, to the very beginning, 0 years into the decay. We'll keep track of the time elapsed, the number of half-lifes, and the percent of carbon-14 remaining:
0 years (0 half-lives) - 100%5,730 years (1 half-life) - 50%11,460 years (2 half-lives) - 25%17,190 years (3 half-lives) - 11.5%22,920 years (4 half-lives) - 6.25%That last one represents our situation, so the fossil is 22,920 years old.

B) One scientist carries out the same experiment performed by another scientist to validate the results.
Explanation:
repetition definition is basically B.
One scientist carries out the same experiment performed by another scientist to validate the results. Therefore, option (B) is correct.
What is repetition?Repetition in science is the process of repeating an experiment or study to verify or validate the results. This is done to ensure that the results are accurate and reliable, and not due to chance or experimental error.
An example of repetition in science is when one scientist carries out the same experiment performed by another scientist in order to validate the results and confirm that they are accurate and consistent. This process helps to build confidence in the results and increases the credibility of the scientific findings.

Transcribe the following DNA strand. Then translate the tRNA strand you wrote.
Answer:
Transcription into mRNA strand will produce: ACU CAG CUG ACC GAC UGG CAU CUG
Translation into amino acid sequence will yield: Threonine- Glutamine- Leucine- Threonine- Aspartic acid- Tryptophan- Histidine- Leucine
Explanation:
- Transcription is the process by which DNA template is used to synthesize a mRNA molecule in the nucleus (eukaryotes). The transcription, which is carried out by an enzyme called RNA polymerase, follows the complementary base pairing rule i.e. A-T, G-C. Note that Uracil replaces Thymine in the RNA molecule.
Based on this question in which a DNA strand was given as follows: TGA GTC GAC TGG CTG ACC GTA GAC
The mRNA strand that will result from transcribing this DNA will be: ACU CAG CUG ACC GAC UGG CAU CUG
- Translation is the process by which mRNA strand is used to synthesize amino acid sequence (protein) in the ribosomes. In the mRNA sequence, nucleotides are read in a group of three called CODONS. Each codon specifies an amino acid. Based on the mRNA sequence as follows: ACU CAG CUG ACC GAC UGG CAU CUG, the amino acid sequence that will result after using the genetic code will be: Threonine (Thr)- Glutamine (Gln)- Leucine (Leu)- Threonine (Thr)- Aspartic acid (Asp)- Tryptophan (Try)- Histidine (His)- Leucine (Leu).

Describe the movement of oxygen molecules if there were more oxygen molecules
outside the cell
Explanation:
Because there's a higher concentration of oxygen molecules outside the cell compared to the cell's cytoplasm, you'll see that oxygen diffuses into the cell along this concentration gradient. ... Because the molecules are moving at random, some will move out of the cell, but most will be moving in in this case.
Transporation is the mechanism by which the molecules and enzymes move in and out of the cell. When more oxygen is present outside the cell diffusion will occur along the concentration gradient.
What is diffusion?Diffusion is a transportation mechanism that involves the movement of the ions and the molecules from the high concentration area towards the low concentration region.
The high amount of oxygen present outside the cell will diffuse through the cell membrane inside the cell along the concentration gradient so that the concentration inside and the outside achieves equilibrium.
Therefore, the movement of the oxygen molecules from high concentration to low is diffusion.

F. Oxytocin
G. Antidiuretic hormone (ADH) or vasopressin
H. Follicle-stimulating hormone (FSH)
I. Thyroxine (T1)
J. Calcitonin
Answer:
A. Growth hormone- anterior pituitary
Prolactin - anterior pituitary
Adrenocorticotropic hormone- anterior pituitary
Thyrotropic hormone- anterior pituitary
Luteinizing hormone - anterior pituitary
Oxytocin - hypothalamus
Antidiuretic hormone - hypothalamus
Follicle-stimulating hormone- anterior pituitary
Thyroxine (T1) - thyroid gland
Calcitonin - thyroid gland
Explanation:
The growth hormone is released from the anterior pituitary gland. The hormone acts on many parts of the body and promotes growth especially in children.
The hormone prolactin is produced in the anterior pituitary gland during pregnancy in order to develop breast tissues and prepare for milk production.
Adrenocorticotropic hormone (ACTH) helps the body to respond to stress conditions. It stimulates the production of cortisol from the adrenal gland.
TSH is produced by the pituitary gland and controls the production of the thyroid hormones.
Luteinizing hormone is one of the hormones produced by the pituitary gland.
Oxytocin is produced in the hypothalamus and is secreted into the bloodstream directly. It is important in female reproduction and is produced in large amount during labor. It is also released when the nipples are stimulated.
Antidiuretic hormone controls of the amount of water lost via urine. It is produced in the hypothalamus.
Follicle-stimulating hormone is another hormone produced by the pituitary gland. It plays an important role in sexual development especially in women where it controls the menstrual cycle and assists in the growth of eggs.
The thyroid gland produces many thyroid hormones including T1,T2,T3 and T4.
The thyroid gland also produces calcitonin, a hormone secreted by the thyroid gland and regulates the amount of calcium in the blood.
