Se efectúa un experimento en el que a la planta 1 se le suministra CO2 normal pero agua que contiene átomos de oxígeno radiactivos. A la planta 2 se le suministra agua normal pero CO2 que contiene átomos radiactivos de oxígeno. Se permite que ambas plantas efectúen fotosíntesis y se mide la radiactividad del oxígeno gaseoso y los azúcares producidos. Qué planta esperarías que produzca azúcares radiactivos y cuál oxígeno radiactivo, por qué?
Answers
Answer:
The Oxygen liberated in photosynthesis comes from photolysis of water.
The CHO formed from Calvin Cycle during photosynthesis comes from reduction of CO2 with H+ of photolysis of water.
Therefore,since Plant 1 contains labeled Oxygen(from water) it will give radioactive Oxygen as the byproduct of its photosynthesis. It CHO is normal.
However,Plant 2, will contain radioactive CHO,because its radioactive CO2 will be reduced by H+ from photolysis of water to form radioactive labeled carbohydrate(CHO)

How are viruswa different from bacteria ?
Answer: a .viruses are not alive .
Answers
Answer:
Viruses are tinier than bacteria. In fact, the largest virus is smaller than the smallest bacterium. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host.
So life itself is an emergent, complex state, but it is made from the same fundamental, physical building blocks that constitute a virus. Approached from this perspective, viruses, though not fully alive, may be thought of as being more than inert matter: they verge on life.
Explanation:
If the surface soil is saturated and precipitation increases, there will be
a. a decrease in the surface elevation of the lake
b. a decrease in the amount of groundwater
c. an increase in the rate of capillarity
d. an increase in the amount of runoff
Answers
The correct answer is D. An increase in the amount of runoff
Explanation:
Surface soil is considered to be "saturated" if soil cannot absorb more water as all pores in it are already filled. This can occur when there has been a lot of precipitation, or the retention of soil is low. Additionally, when soil is saturated and it is in contact with more water (for example, if precipitation increases) the water will not be absorbed by the soil but will flow to other areas, which is known as runoff. Thus, if the surface soil is saturated and there is precipitation, there will be an increase in the amount of runoff.

Which is not a product of photosynthesis?
water
oxygen
glucose
nitrogen
Answers
Answer:
nitrogen
Explanation:
Plants use photosynthesis by taking in water and carbon dioxide and releasing oxygen while consuming food (glucose) for itself. Therefore, your answer is nitrogen. No nitrogen is created during this process
Answer:
Nitrogen
Explanation:
Photosynthesis is a process used by autotrophs and producers, like plants, algae, and some bacteria. In this process, water, carbon dioxide and light energy from the sun are turned into glucose and oxygen. The glucose becomes food for the organism, and the oxygen becomes the waste product.
There is no nitrogen involved in photosynthesis. It is not created, and therefore is not a product. The best answer choice is nitrogen

Intracellular transport, changes in cell shape, cell motility and animal locomotion depend on the microtubules, microfilaments, motor proteins and their accessory proteins. You should be able to explain how each of these four movement functionsabove are achieved by microtubules and microfilaments. Make sure you understand the role of the different motor proteins involved that are specific to microtubule movement vs. microfilament movement. Microtubules and microfilaments also have important roles in the cytoskeleton.
Answers
Answer:
Intracellular transport is taking place with the help of microfilaments and microtubules. The plays the role of a highway for motor proteins such as dynein, kinesin, and myosin, which acts as the car of this highway that helps in transport.
Motor proteins help in changing the ATP to ADP by binding to it and attach or detach to the other parts of the cytoskeleton for transporting the vesicles as these proteins move.
Kinesin and dynein both are microtubule motor proteins. Kinesin transports full vesicles away from the nucleus, Dynein transports empty vesicles back towards the nucleus and myosin is a microfilament motor protein that transports both vesicles along microfilament.

Which of the following is NOT a reason bacteria are good for genetic engineering? A. Their DNA accepts new genes more easily than Eukaryotes. B. DNA is easy to access and modify. C. They replicate very quickly. D. Plasmids can be engineered easily to produce proteins.
Answers
Answer:
D
Explanation:
"Scientists insert genes into loops of DNA called plasmids using natural processes and technological innovations. They can then introduce plasmids into bacteria or other cells, which replicate the inserted genes or induce the cells to produce such valuable proteins as human insulin and growth hormone."
The following is not a valid reason that indicates bacteria are good for genetic engineering:
Plasmids can be engineered easily to produce proteins.Thus, the correct option is D.
What is Genetic engineering?Genetic engineering may be defined as a methodology that utilizes laboratory-based technologies and equipment that support in the alteration of the DNA makeup of an organism.
A plasmid is a genetic structure that mediates the translocation of the genetic material of one organism to another for the purpose of modification.
Examples include insulin production, hormone synthesis, increase productivity in plants, etc.
The Plasmid is inserted into bacterial cells when the genetic material of the experimental organism is successfully employed. This process does not deal with the reason that bacteria are good for genetic engineering.
Therefore, the correct option is D.

Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.
Answers
I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster.

What is the potential problem for robotic rovers on Mars?
Answers
Answer:
The limited autonomy of the robotic rovers on Mars posed a big problem.
Explanation:
Missions are very costly, and can lead the project to fail with the simplest errors. If the rover was permanently trapped on a rock or destroyed, it would have a catastrophic impact on the exploration. Thus on-board technologies would still be more traditional than what a laboratory environment has sought. The autonomous rovers will considerably increase the productivity of crew. Responsibility for their own well-being is also useful for the rovers: to prevent getting hurt, to recognize and correct recoverable hardware and software faults.
What types of enzymes play a catalytic role in the regulation pathway of ubiquitination?
Answers
Answer:
ubiquitin activating enzyme ( E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin ligase (E3).
Explanation:
In ubiquitination, ubiquitin (regulatory protein) attach to a protein to inactivate it and targets a protein for degradation via the proteasome.
There are three enzymes sequentially catalyse the process of ubiquitination that includes ubiquitin activating enzyme ( E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin ligase (E3).
The E1 activates ubiquitin by forming a thiol ester bond between the C terminus of ubiquitin and the active cysteine of the E1 which is an ATP dependent step.
The activated ubiquitin then tranferred to cysteine of E2 which along with E3 transfers the ubiquitin to a lysine residue in the target protein.
Hence, all three ubiquitin activating enzyme ( E1), a ubiquitin conjugating enzyme (E2), and a ubiquitin ligase (E3) enzymes sequentially catalyse the process of ubiquitination.
