Describe the movement of oxygen molecules if there were more oxygen molecules
outside the cell

Answers

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.

Transcribe the following DNA strand. Then translate the tRNA strand you wrote.

Answers

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).

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

Answers

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.

Recall the Jagendorf experiment (pasted below) was conducted wholly in the dark. Hypothesize what would happen if you were to mimic the experiment, but rather than alter pH, you place your thylakoids in a beaker with a solution that mimics the chloroplast stroma in direct sunlight. What would be the result?

Answers

Answer:

ATP production.

Explanation:

The result will be the production of ATP molecules if we place thylakoids in a beaker with a solution that mimics the chloroplast stroma in direct sunlight. The thylakoids are able to formed ATP in the dark because H+ gradient is required for ATP synthesis. The scientists find out that the light reactions were not necessary to establish the H+ gradient required for ATP synthesis by ATP synthase.

Answers

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.

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

Answers

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.

A is the answer, because animal cells separate with no assistance, but in plant cells they must form a cell brocade that later turns into a cell wall for the newly formed cell.

What happens in the postsynaptic neuron when excitatory neurotransmitters bind to receptors?

Answers

Answer:

it causes the depolarization of the target cell

Explanation:

Glutamate is an excitatory amino acid neurotransmitter that binds to specific receptors on the surface of target cells and thus causes its depolarization. During glutamate-mediated depolarization, the difference in charge inside and outside the cell is lost due to the entry of sodium and calcium positive ions into the postsynaptic cell (neuron) through specific ion channels. Moreover, glutamate binding also leads to the exit of potassium ions from the cell, thereby resulting in excitation. Through this mechanism, glutamate regulates many signaling pathways, such as those involved in memory, learning, emotions, cognition, motor control, etc.
