Please read the following scenario to answer the following question. While working with cultured mouse cells, a researcher unknowingly treated the cells with a mutagen that causes the deletion or insertion of individual nucleotides in DNA. Subsequently, the researcher isolated and cultured a single cell from this group and noticed that the progeny of this cell were not producing a certain protein, and that this affected their survival. The mutation would be most harmful to the cells if it resulted in ________
Answer:
deletion or insertion of nucleotide from or in any coding sequence of the DNA
Explanation:
The mutation would be most harmful to the cells if it resulted in the deletion or insertion of nucleotide from or in any coding sequence of the DNA.
Deletion or insertion of a nucleotide from/into the coding sequence of DNA results in a frameshift mutation away from the original protein. Deletion/insertion of a nucleotide from/to the coding sequence of a DNA can cause a totally different protein to be synthesized from such DNA or, worse still, results in a nonfunctional protein. Both results could be grossly harmful to the cells.
What causes the earths tides; describe the conditions for the largest tides?
Answer:
Earth's rotation and the gravitational pull of the sun and moon create tides on our planet. Because the sun is so much larger than the moon (27 million times more masssive), it has a much bigger graviational pull on Earth.

What would you look for under a microscope on a slide with meiotic cells if you wanted to identify metaphase I
Answer:
This question lacks options, options are: A) A visible nuclear envelope B) Separated sister chromatids at each pole of the cell C) Tetrads lined up at the center of the cell D) A synaptonemal complex E) A cleavage furrow. The correct answer is C.
Explanation:
During Metaphase I, the chromosomes line up at the midpoint or equator between the poles of the cell and are found at their thickest and shortest structure, that is, the tetrads line up at the equator of the cell. They are identified as two double longitudinal sister chromatids. In animals and plants, the chromatids are connected (at their centromeres) to the fusiform apparatus, which has formed between the two centrioles located at the poles of the cell. In many plants, the centrioles are absent. However, the spindle is still present and the plant chromosomes are attached similarly to the microtubule fibers of the spindle.

What gametes are produced by the following organisms:_______.
a. Genotype YyRr, if Y and R are on different chromosomes
b. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over
c. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over
d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
Answer:
The correct answer would be -
1- YR, Yr, yR and yr.
2. Yr, yR
3. YR, yr
4. YR, Yr, yR & yr
Explanation:
A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.
The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.
1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.
2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.
3). if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.
4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.

What do we still need to know in order to determine why the two rock formations have such similar minerals?
Answer and Explanation:
Rock is defined as the collection of one or more minerals. Granite, sedimentary rock, igneous rock, metamorphic rock and limestone are the types of rock. Granite is the most common type of rock. Granite is made up of four minerals such as hornblende, feldspar, quartz and mica. Granite breaks down to form sedimentary rocks. Igneous rock begins as magma. The lava and magma harden to form igneous rock. Metamorphic rocks are made from pressure. Rocks are made of one or more minerals, which are cooled and melted together, cemented together, or heated and squeezed together. The mineral occurs naturally and is made of crystals. The earth’s crust is made of rocks. Most rocks are covered by soil. Soil contains the small pieces of rocks. The two rocks have similar composition but different texture. Rocks are formed in different ways. The rocks can be changed from one form to another.
What kinds of characters can you use to create a data matrix for estimating phylogenetic trees?
a. any heritable trait.
b. any morphological trait.
c. any molecular trait.
d. any measurable trait.
Answer: The correct option is A
any heritable trait
Explanation:

Answer:
no
Explanation:
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).
You are a glucose molecule in a disaccharide found in a drink that was sipped by an athlete who is about to begin running a 1600m (1 mile) race. Put the words in the list below in the appropriate order to describe the process of your journey from the mouth and ultimately to the muscle cells for energy.
a. electron transport system
b. active transport
c. stomach
d. pyruvate
e. brush border disaccharidases
f. carbon dioxide and water
g. mouth
h. citric acid cycle
i. glucose transporters
j. duodenum
k. glycolysis
l. jejunum
m. blood
n. esophagus
Answer:
Mouth -Esophagus-- Stomach -Duodenum -Jejunum -Brush border disaccharidases--Glucose transporters--Active transport--Blood-Glycolysis-Pyruvate--Citric acid cycle - Carbon dioxide and water : )
Explanation:
The journey of a glucose molecule from the mouth and ultimately to the muscle cells for energy in the correct order is:
Mouth > Esophagus > Stomach > Duodenum > Jejunum > Brush Border Disaccharidases > Blood > Glucose Transporters > Glycolysis > Pyruvate > Citric Acid Cycle > CO2 and Water > Active Transport > Electron Transport System.
The drink rich with disaccharides starts its journey from the mouth cavity and moves through the esophagus to the stomach. The disaccharide digestion takes place when it reaches the jejunum through the duodenum of the small intestine by enzyme maltase that also presents in Brush Border Disaccharidases to glucose.
Glucose moves o blood and through a glucose transporter for cellular respiration that starts with glycolysis that converts glucose to pyruvate and enters in TCA cycle and releases CO2 and water as byproducts that ultimately moves to the ETS system to provide energy to the muscles.
Thus, the correct answer is - given above in the correct order.

when you move your hand up and down while holding on a jump rope, you make a wave. What is the medium
Answer:
The medium of the wave is the Rope.
Explanation:
This is because it is transverse wave and transverse wave need a medium to transfer energy and this is because in transverse wave,particles of the medium move in a direction that is perpendicular to the direction of the transverse wave. From the question, when you move you hand up and down, you make a wave and the direction of the wave is also up and down which is perpendicular to the direction of the wave.
