Answer:
electrochemical proton gradient
Explanation:
The electrochemical proton gradient is defined as the difference in the proton concentration or hydrogen ions (H+) concentration across a inner mitochondrial membrane during the electron transport chain.
The electrochemical proton gradient is build due to the active transport of ions across the cell membrane which is useful for ATP synthesis during the electron transport chain by the coupling of the electrochemical gradient across the membrane.
Hence, the term used is electrochemical proton gradient.

Why the rainforest in Costa Rica is not rich with plants? Remember to use scientific language
Answer:
Deforestation is the major problem causing lack of rich species in Costa Rica. This is due to over grazing by cattle.This may lead to flooding which affect fertility of the soil.These animals graze on the plants without regulations,and cause erosion as their hoofs percolate the soil, further reducing soil fertility.
In addition to sustain the beef production, trees were fell to for cattle ranching.This ultimately contributed to loss of the forest species.
Banana plantation is an additional factor.Forest were cleared to cultivate banana, which affects forest population.

The Eocene period exists in Earth’s history around 34 MYA. What could a scientist do to determine what era the Eocene period belongs to on the geologic time scale?
Answer:
To understand what era the Eocene period belongs to on the geologic time scale, the scientist would have to examine the Cenozoic era to understand all information related to it.
Explanation:
First, let's start with an explanation of terms.
MYA simply means Millions of Years Ago Time Scale is a sequence or organisation of events which is used as a yardstick to measure the duration of history or how long the earth has existed. Eocene Period refers to the geological epoch that lasted from about fifty-six to approximately forty MYA. It is also defined as the second epoch of the Paleogene Period within the modern Cenozoic Era.
Given the definition of the Eocene Period, to understand what era an Eocene period belongs to, the person must carefully study the Cenozoic era.

What types of enzymes play a catalytic role in the regulation pathway of ubiquitination?
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.

Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.
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. Hope this helps.

Which is not a product of photosynthesis?
water
oxygen
glucose
nitrogen
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
Name the ionic compound PbCO3
Answer:
lead carbonate
Explanation:
The ionic compound PbCO3 is called lead(II) carbonate.
Let's break down the name to understand it better:
1. The symbol "Pb" represents the element lead.
2. "CO3" is the chemical formula for carbonate, which is a polyatomic ion consisting of one carbon atom and three oxygen atoms.
To name the compound, we use the Stock system for naming compounds containing transition metals like lead.
1. The Roman numeral "(II)" indicates the charge of the lead ion in the compound. In this case, lead has a +2 charge. The Roman numeral helps differentiate between different possible charges of the metal ion.
2. The word "carbonate" represents the polyatomic ion CO3.
Therefore, the name of the ionic compound PbCO3 is lead(II) carbonate.

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.
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.

What is the potential problem for robotic rovers on Mars?
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.

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
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.
