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:
Because oxygen is circulated throughout the body via the bloodsteam, there is a strong connection between the cardiovascular system and the ________________ system.
Group of answer choices
respiratory
digestive
endocrine
nervous
Answer:
Because oxygen is circulated throughout the body via the bloodstream, there is a strong connection between the cardiovascular system and the respiratory system.
Explanation:
The cardiovascular system is responsible for the transport of oxygen to all tissues of the body, in addition to the removal of carbon dioxide, which depends on the close interaction with the respiratory system.
A summary of the strong connection between the cardiovascular and respiratory systems is :
Blood contains red blood cells, which are responsible for transporting O₂ and CO₂ by binding to the hemoglobin molecule, present in these structures. The respiratory system is responsible for providing air with O₂ and removing CO₂, a process that depends on gas exchange at the level of the pulmonary alveolus.

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
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.
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.
When large masses of magma solidify far below Earth’s surface, they form igneous rocks that have a _____.
Answer:
coarse-grained texture
Explanation:
Igneous rocks come from magma of volcanos and they cool and end up becoming hard. A perfect example of this is granite, which contains a lot of minerals such as quartz and feldspar. Igneous rocks contain a lot of minerals hence why they have a coarse-grained texture.

Explanation:
Pickling has been used to preserve foods for over 4000 years. Research how foods are pickled and relate your experimental results to this preservation technique.
Answer:
by increasing food acidity, thereby microorganisms cannot survive.
Explanation:
Pickling can be defined as the techniques used to preserve and extend food shelf life of food by increasing acidity, which is achieved by using vinegar or by brine fermentation, i.e., by bacteria that increase acidity when they produce acid lactic. In consequence, foods that serve as a microhabitat for microorganisms that affect their shelf life cannot survive and grow. The foods treated by pickling may take a different coloration, taste, texture, etc. The time of this process varies depending on the applied technique from hours to many days (or longer).

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.
If the frequency of the disorder in the population is 0.0070, what is the percentage of heterozygous carriers
Answer:
15.322 %
Explanation:
Supposing that this is a recessive disorder and the population is in Hardy-Weinberg equilibrium:
p² + 2pq + q² = 1, where
1- the genotypic frequency of the homo-zygous dominant allele is p²,
2- the genotypic frequency homo-zygous recessive allele is q², and
3- the genotypic frequency heterozygous allele is 2pq
Therefore:
q² = 0.007 >> q = √ 0.007 = 0,0836
p = 1 - q = 1 - 0,0836 = 0.9164
2pq = 2 x 0.9164 x 0,0836 = 0.15322 (or 15.322 %)
A population has 1000 individuals. A PCR analysis of the genotypes of a gene associated with Lactase persistence are: LL = 450 Ll = 250 ll = 300. What are the allelic frequencies of the L and l alleles?
Answer:
L allele: 0.575 (or 57.5%)
l allele: 0.425 (or 42.5 %)
Explanation:
Homo-zygous individuals have two copies of the same allele (i.e., either L alelle or l allele), while heterozygous individuals carry both alleles at a time (i.e., one L allele and one l allele). In consequence:
- Frequency of the L allele: [(450 x 2) + 250] / 2000 = 0.575
- Frequency of the l allele: [(300 x 2) + 250] / 2000 = 0.425
