What is the difference between active transport across a cell membrane and diffusion across a cell membrane?

Answers

Answer 1
Diffusion is the net movement of particles from a region of high concentration to a region of low concentration. Down a concentration gradient.

Active transport is the net movement of substances against concentration gradient using energy from respiration.

The hormones that can be taken orally because they are lipid-soluble and diffuse across the digestive system wall include Prednisone, Testosterone, Thyroid hormone and Cortisone.

Steroid hormones are liposoluble hormones that can translocate through cell membranes.

Prednisone is a synthetic hormone similar to cortisone.

Cortisone is a corticosteroid hormone secreted by the adrenal glands.

Thyroid hormones are liposoluble hormones secreted by the thyroid gland.

Testosterone is a steroid hormone produced by the testicles in males and by the ovaries in females.

Diploid somatic cells
Haploid gametes
Diploid gametes

Answers

Answer:

Explanation:

Haploid somatic cells

Answer:

Haploid because during meiosis one cell divides twice to for four daughter cells.

Explanation:

You are performing an experiment with Primase, using a specific DNA template. In this experiment, you provide NTPs (ATP, UTP, CTP, GTP) which contained only one radioactive phosphate group, in the alpha-phosphate position (the alpha- phosphate is the one attached to the sugar. the other phosphates are beta and gamma). After RNA synthesis occurs, you separate the resultant RNA strand any of the NTPs that have not been incorporated into the RNA, and measure the radioactivity of the newly synthesized RNA.A) In this experiment, would you expect the newly synthesized RNA be radioactive? Explain why.B) If you forgot to add CTP when you did the experiment, would the resulting RNA be radioactive?C) If you did the experiment, with all the NTPs provided, but only the beta phosphate was radioactive for each of the NTPs, would radioactivity be found in the RNA? Explain why.D) If you did the experiment, with all the required NTPs, but only the ATP was radiolabelled Would radioactivity be found in the RNA? Explain why.

Answers

Answer:

(a). Yes.

(b). RNA becomes Radioactive.

(c). No.

(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.

Explanation:

So, let us do right into the explanation behind the answers to the questions asked.

(a). The answer to this part of the question is "Yes" because in creating or in the formation of the glycosidic bond, all the alpha phosphate group were taken into consideration that is they were all used, thus making the newly synthesized RNA to be radioactive.

(b). The RNA becomes Radioactive is the answer to this part of this question because CTP is needed in the experiment.

(c). The answer to this part (c) of this question is ''No'' because the only thing that takes part in bonding is the alpha phosphate.

(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.

The fungus Melampsora lini causes a disease known as flax rust. Different strains of M. lini cause varying degrees of the rust disease. Conversely, different strains of flax are resistant or sensitive to the various varieties of rust. The Bombay variety of flax is resistant to M. lini-strain 22 but sensitive to M. lini-strain 24. A strain of flax called 770B is just the opposite; it is resistant to strain 24 but sensitive to strain 22. When 770B was crossed to Bombay, all F1 individuals were resistant to both strain 22 and strain 24. When F1 individuals were self-fertilized, the following data were obtained:

43 resistant to strain 22 but sensitive to strain 24
9 sensitive to strain 22 and strain 24
32 sensitive to strain 22 but resistant to strain 24
110 resistant to strain 22 and strain 24

Required:
Explain the inheritance pattern for flax resistance and sensitivity to M. lini strains.

Answers

Answer:

Explanation:

Using the Mendelian approach to solve this question, we will understand that the mendelian approach has a pattern for inherited traits.

From the data set given, the total number of the population is:

43+9+32+110 = 194

However, their ratio are being calculated as follows:

43/194 = 0.22

9/194 = 0.05

32/194 = 0.16

110/194 = 0.57

After comparison with the Mendelian's approach, we realize that these results seem to be similar to the 9:3:3:1 ratio.

i.e.  

3/16 = 0.18

1/16 = 0.06

3/16 = 0.18

9/16 = 0.56

The inheritance pattern obviously dictates that the flax experiment proceeds in the pattern found in the Mendelian's Approach and the resistance of the two different strains were arbitrated by two traits.

Calculate the rate of photosynthesis (mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 3 mm from the initial level in 20 min, and when measuring cellular respiration it took 15 minutes for the water level to move down 1 mm.

Answers

Answer:

The rate of photosynthesis is 13 mm/hr

Explanation:

The rate of net photosynthesis is given by;

rate of net photosynthesis = 3 mm / 20 min = 1.5 mm/ 10 min

The rate of  cellular respiration is given by;

rate of cellular respiration = 1 mm / 15 min = 0.667 mm / 10 min

The rate of photosynthesis is given by;

rate of photosynthesis = rate of net photosynthesis + rate of cellular respiration

rate of photosynthesis = 1.5 mm/ 10 min + 0.667 mm / 10 min

rate of photosynthesis =2.167 mm/ 10 min

[tex]rate \ of \ photosynthesis \ in \ mm/hr = \frac{2.167 \ mm}{10 \ min} *\frac{60 \ min}{1 \ hr} = 13 \ mm/hr[/tex]

Therefore, the rate of photosynthesis is 13 mm/hr

I NEED HELP ASAP Sensors on a spider's legs feel the vibrations of a trapped insect and relay the information to the spider's brain through nerve electrical signals. For nerve cells to maintain these electrical potentials, sodium must be removed from the cell and potassium must be moved into the cell. Describe why this process is a form of active transport and what is required for active transport to occur?

Answers

Answer:

Please find the explanation below

- Energy (ATP) is needed for active transport to occur

Explanation:

According to this question, sensor's on a spider's legs relay information via nerve electrical signals to the brain when the vibrations of a trapped insect is felt. However, for nerve cells to maintain this electric potential, ACTIVE TRANSPORT must be carried out by removing sodium from the cell and potassium must be moved into the cell.

This is a form of ACTIVE TRANSPORT because pottasium ions are moved into the cell against concentration gradient i.e. from a region where it is in low concentration to where it is in high concentration. This active transport process is usually accompanied by the use of energy in form of ATP.

And above all I would suggest we plant lots and lots of trees that could be a good help because trees consumes the bad gas and release the good gases into our atmosphere which does not burn the ozone layer and climate change won't be a national issue.

First of all, humans must demand and call out large fossil-fuel/oil companies to transition into the renewable energy industries. Fossil-fuels account for over 75% of the world’s greenhouse-gas (GHG) emissions, and unless rapid action is taken, the wildfires will continue to burn, the ice caps will continue to melt, and more and more species will become extinct. If awareness is spread, and worldwide politicians de-politicize this issue, humanity will take action. However, if we, as a society, continue as we do—as if there is no problem at hand—humanity will take action when it is too late. This is largely attributed that most people do not welcome drastic change, and wish for life to remain as normal. Some also do not welcome the scientific findings, as it provides a harrowing, bleak prediction if little change is made. Overall, humanity must act swiftly and united on the issue to ensure the wellbeing of our posterity.

Answers

Answer/Explanation:

The endosymbiotic theory is the idea that eukaryotic cells evolved from the fusion of two prokaryotic cells that formed a symbiotic relationship, with one living inside the other.

An endosymbiont is one organism that lives inside another one.

The existence of mitochondria and chloroplasts, which contain their own DNA and ribosomes, supports this theory. Mitochondria are chloroplasts were once free-living organisms,  they were prokaryotes that ended up inside of other cells.

Mitochondria and chloroplasts have genes that are very similar to the genes of prokaryotes. Their membranes look like the prokaryotic cell membrane, and they divide  in similar ways.
