imagine that astronomers found a galaxy that was 20 billion light years from the earth how would they have to revise the bug banf theory to account for such a discovery!!!!
Answers
Answer:
Not necessary.
Explanation:
No need for the revision of big band theory because this galaxy may be a product of big band event. At the start this galaxy is shorter and hot but with the passage of millions of years, this galaxy also expands and formation of stars and planets occurs. The stars and planets that are present in the galaxy occurs due to different events that is responsible for their current conditions. This formation of stars and planets needs millions of years.

what is osmoregulation
Answers
Answer:
Osmoregulation is a process that regulates the osmotic pressure of fluids and electrolytic balance in organisms. In animals, this process is brought about by osmoreceptors, which can detect changes in osmotic pressure. Humans and most other warm-blooded organisms have osmoreceptors in the hypothalamus. Besides the brain, osmoregulators are also found in the kidneys..

A scientist is trying to isolate a penicillin-resistant His- bacterial mutant from a mixed population. To isolate penicillin-resistant mutants, the scientist must inoculate the parent population on plates containing ______; this approach is ______ selection.
Answers
Answer:
Penicillin, direct
Explanation:
this scientist has to inoculate the parent population using plates that contains penicillin in them. we call this approach the direct selection.
In the direct selection, bacteria is grown on a material that has penicillin in it. the goal is to find mutants that have resistance to penicillin. only these resistant ones would grow and then a direct identification would be done.

1.Write the equation for light dependent reaction of photosynthesis
2.Write the Equation for light independent reaction of Calvin cycle?
Answers
Answer:
1. The overall chemical equation of the light-dependent reactions is given below:
12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP
2. The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :
3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi
Explanation:
1. The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH which are used light-independent reactions to drive the synthesis of sugar molecules from inorganic CO₂ and water. Light-dependent reactions takes place in photosystem I and II. Photosystem I and Photosystem II ( PS I and PS II) are the two biochemical systems, active in chloroplasts, that serve as sites of electron transfer reactions in photosynthesis. Energy from sunlight is used to split water which releases electrons and hydrogen atoms which are transferred to NADP+ to produce ATP and NADPH and oxygen is produced as a waste product.
The overall chemical equation of the light-dependent reactions is given below:
12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP. Note that Pi refers to inorganic phosphate
2. The Calvin cycle refers to the light-independent reactions in photosynthesis. It occurs in three stages.
Stage 1 (Carbon fixation): In this first stage of the Calvin cycle, light-independent CO₂ is fixed by enzyme called ribulose bisphosphate carboxylase (RuBisCO) to ribulose bisphosphate (RuBP) to form glyceraldehyde-3-phosphate.
Stage2: ATP and NADPH are used to reduce 3-phosphoglycerate (3-PGA) into glyceraldehyde--phosphate (G3P). ATP and NADPH are used up in the process and are converted to ADP and NADP+, respectively.
Third stage: RuBP is regenerated, which enables the system to prepare for more CO2 to be fixed.
The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :
3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi

1..Do you think Earth’s continents and oceans will look the same in the future as they do now? Why or why not? Use evidence from the activity to support your ideas..
2..Earth’s plates are constantly moving, yet Earth’s surface looks relatively the same each day. Why don’t we observe changes to Earth’s surface every day?..
Answers
Explanation:
1.No, due to global warming the rise in temperature will slowly vaporises the water from oceans.On the other hand, the tectonic plates and the decrease of water level from water resources leads to the unification of land in a fixed way.
2.As tectonic plates are much located inner the earth than we expected.And, the earth is huge so we can't see small changes occuring through natural phenomena
How can a poly genic trait be easily identified
Answers
Answer: The presence of the polygenic trait masks the other possible alleles involved. There are only two possible phenotypes for the trait. The graphing of the possible phenotypes results in a bell curve. Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall.
