ll of these are important functions of iron EXCEPT _______. a. aids in enzymatic activity for energy metabolism b. prevents anemia c. acts as a buffer d. transports oxygen in the blood
Answer:
c. acts as a buffer
Explanation:
As we know that the iron plays a vital role and the vital functions in our body. It is an important hemoglobin component. Due to this it help in transporting the oxygen and prevent anemia also it acts as a cofactor in form of glycolysis and metabolism of energy
Therefore as per the given statement, the option c is the correct one

Explanation:
The illustration shows one of the ways resources are removed from the deep sea. Describe what type of resources these are, including if they are renewable or non-renewable. Predict two consequences to the seafloor life if this process is not regulated.
Answer:
Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.
Explanation:
The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.
The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.
Two possible consequences of not regulating marine mining are:
Destruction of the habitat of life forms present on the sea floor, which endangers many species and even forces migration to more stable areas, with consequences on the food chains.Extinction of marine species that inhabit the seabed. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.
In the Southern Hemisphere, western boundary currents generally flow:
northward

Which statement best explains why different portions of the Moon are visible at different times of the month? *
1 point
As Earth moves along its orbit, it blocks different parts of the Moon.
As the Moon moves along its orbit, it passes through Earth's shadow.
As the Moon moves along its orbit, only a fraction of it is visible from Earth
As Earth moves along its orbit, its shadow falls on different parts of the Moon
Answer:As the Moon moves along its orbit, only a fraction of it is visible from Earth
Explanation:
The different portions of the Moon are visible at different times of the month as as the Moon moves along its orbit, only a fraction of it is visible from Earth.
What is moon orbit ?
The moon travels across the Earth in an elliptical orbit, a barely stretched-out circle. When the moon is closest to Earth, its rotation is slower than its adventure via space, permitting observers to look an extra eight tiers at the jap side.
Different quantities of the moon are seen at special instances of the month due to the location of the moon in its orbital path. From Earth, we're in reality viewing the sun's rays being pondered off diverse quantities of the moon's floor all through its orbit.

Large scale adaptations of the two-hybrid technique have allowed for determining many protein interactions at once using:______.a. systems biology.b. nuclear magnetic resonance imaging.c. mass spectrometry.d. protein microarrays.
Answer: systems biology
Explanation:
A two-hybrid technique is a technique that can be used to know the protein-protein interactions or the protein-DNA interactions. This is done through the test for physical interactions that exist between the two proteins or the proteins and their DNA molecules.
It should be noted that large scale adaptations of the two-hybrid technique have allowed for determining many protein interactions at once using systems biology. It should be noted that systems biology focuses on the complex interactions that are within the biological systems.
What are the advantages and disadvantages of anaerobic fermentation?
Answer:
- Advantages: doesn't need oxygen, it is faster than aerobic metabolism
- Disadvantages: less energy is produced for every molecule broken down
Explanation:
Anaerobic fermentation (also known as acid lactic fermentation) is a group of O2-independent metabolic reactions where glucose and other sugars are converted into energy (especially ATP, the energy currency of the cell) and lactic acid. This metabolic pathway occurs in types of bacteria and specific animal cells (for example, muscle cells). In contrast to aerobic respiration, the amount of energy produced by the anaerobic pathway is much smaller because it does not involve ATP production by the Krebs cycle or electron transport chain (the aerobic pathway generates up to 38 ATP molecules per glucose, while the anaerobic pathway produces only 2 ATP molecules per glucose). Moreover, anaerobic fermentation produces lactic acid that may be absorbed by the liver (too much lactic acid may have harmful effects). Finally, it is also important to note that the anaerobic pathway is faster than aerobic metabolism.
Which of the following shows a correct base pairing in DNA?
OA and G
OG andc
OCand A
OT andG
Answer:
the correct base pairing in DNA is G and C.
Explanation:
The pyrimidine cytosine(C) always pair with purine guanine(G)
The one that is showing correct base pairing in DNA is G and C. The correct option is B.
For DNA to be stable and maintain its integrity, the proper base pairing is essential. Adenine (A) pairs with thymine (T), and cytosine (C) couples with guanine (G), according to the base pairing laws.
As a result, the base pairing in DNA represented by G and C is correct. The two strands of the DNA double helix are kept together by the hydrogen bonds that form between the bases.
While cytosine and guanine make three hydrogen bonds, adenine and thymine only form two.
The correct replication and transcription of DNA as well as the generational transmission of genetic information are all made possible by this complimentary base pairing.
Thus, the correct option is B.

Which scientific discipline is correctly matched to a contribution to society?
The options are;
A) biology; theory of relativity
B) geology; theory of continental drift
C) ecology; discovering new elements
D) astronomy; developing quantum mechanics
Answer:
B) geology; theory of continental drift
Explanation:
Looking at the options;
-theory of relativity is a topic in physics originated by Einstein. Thus, it is matched to physics and not biology.
- theory of continental drifts are related to plate tectonics where it explains how continents shift position on Earth's surface. This is a branch of Geography and is thus correctly matched.
- discovering new elements is a topic under chemistry and not ecology. Thus, this is not matched correctly.
-developing quantum mechanics is a topic in physics that deals with the relationship between energy and matterwith respect to atomic and subatomic scale. Thus, it is not well matched.
Therefore correct answer is option B
Cofactors for some enzymes are not considered prosthetic groups because they are loosely held during the course of reaction.A. TrueB. False
Answer:
True
Explanation:
Cofactor is a biological term used in describing a form of a non-protein chemical compound. It is highly required in the biological operation. It is in two types, the Coenzymes and Prosthetic groups.
While the Prosthetic groups are well connected to an enzyme, the coenzymes on the other hand are conected to an enzyme loosely.
Hence, it is TRUE that Cofactors for some enzymes are not considered prosthetic groups because they are loosely held during the course of the action
Why do fishes die when they are taken out?
Answer:
Fishes take oxygen through their gills. Gills are richly supplied with blood capillaries and can readily absorb oxygen dissolved in water. Gills of fishes are not equipped to take in gaseous oxygen (oxygen from air). Hence, a fish when taken out of water is unable to inhale oxygen rich air and so, dies quickly.
