About three billion years ago, single-celled organisms called cyanobacteria lived in Earth’s oceans. They thrived on the ocean’s abundance of carbon-di-oxide , which they used during the process of photosynthesis. Much later, this process allowed organisms, such as fish, to survive by extracting dissolved oxygen from ocean waters.

Explanation:

Cyanobacteria is the bacteria that is primitive form of bacteria that used to be first organisms even before the present day bacteria came into existence. They were able to do photosynthesis.

Cyanobacteria used the huge concentration of carbon dioxide that was mixed with the sea water. This carbon dioxide was picked up by millions of cyanobacteria that converted the carbon dioxide into useful glucose and other products and valuable oxygen. Thus oxygen came in earth and that was used by future organisms for respiration.  

Cyanobacteria thrived on carbon dioxide in the oceans and through photosynthesis, they released oxygen, which later life forms needed for survival. Therefore, the first blank in the statement should be filled with 'carbon dioxide', and the second one with 'oxygen'.

Answer:

Carbohydrates are hydrophilic  whereas Lipids are hydrophobic.

Explanation:

Carbohydrates can be most commonly understood as hydrates of carbons. They generally contain more than two carbon atoms and are easily soluble in water, thus giving them the characteristics of hydrophilic compounds. Sugar and glucose are some of the important examples of carbohydrates.

On the other hand, lipids comprise a polar region, which attracts water and a much larger non-polar region, which repels water. This non-polar region dominates the polar region of lipid molecules thus making it a hydrophobic compound. Oils, fatty substances, steroids, and waxes are some of the important examples of Lipid molecules.

Cellular respiration breaks down glucose to release energy, with carbon dioxide produced during the Krebs cycle.

Cellular respiration releases energy by breaking down glucose in the presence of oxygen. This complex process involves several stages: glycolysis, the Krebs cycle, and oxidative phosphorylation. The step in the oxidation of pyruvate that produces carbon dioxide is known as the Krebs cycle, also referred to as the citric acid cycle. During this cycle, each molecule of pyruvate (which is derived from glucose) is decarboxylated, releasing carbon dioxide as a byproduct.

The energy originally used to hold these molecules together is harnessed in the generation of ATP, which cells use for energy. In summary, cellular respiration converts the stored energy in glucose into a form that can be used by the cells, producing carbon dioxide and water as waste products.

Explanation:

A Triglyceride is a kind of lipid that can store energy for a long period of time.

Triglycerides are a type of lipid that can store energy for an extended duration. They consist of long chains of carbon and oxygen atoms bonded to a glycerol backbone structure. These molecules serve as the primary form of energy storage in the human body and many other organisms. Each triglyceride molecule contains three fatty acid chains attached to the glycerol backbone. The carbon-carbon and carbon-hydrogen bonds within these fatty acids store a significant amount of chemical energy, which the body can access when needed.

When an organism requires energy, enzymes break down triglycerides into their constituent fatty acids, releasing energy for cellular processes. Excess triglycerides can be stored in adipose tissue, contributing to body fat. While triglycerides are vital for energy storage, elevated levels in the bloodstream can be associated with health issues, such as obesity and heart disease.

The subcellular structure involved in the translation of genetic material in protein synthesis is the ribosome. Ribosomes are the site in the cells where protein synthesis occurs, which is the process where genetic information coded in mRNA is translated into proteins. This process has two main stages: transcription, in which the information from DNA is transferred to mRNA, and translation, in which the mRNA works with ribosomes to produce proteins. Proteins are crucial functional units within the cell and are involved in virtually all cell processes. Ribosomes are found within all living cells and are the place where genetic instruction in the mRNA are read to synthesize proteins in a process called translation.

The phase of mitosis shown in the diagram where chromatids separate from each other and are being pulled to the opposite ends of the cell is **anaphase.** The correct option is 1.

During anaphase, the centromere that holds sister chromatids together splits, allowing the chromatids to become individual chromosomes. These chromosomes are then pulled apart toward opposite ends (poles) of the cell by the contraction of spindle fibers. The movement of chromatids is facilitated by the shortening of microtubules within the spindle apparatus.

The key events of anaphase include:

1. **Separation of Sister Chromatids:** The chromatids, which are identical copies of each other, are separated as the centromere divides.

2. **Movement Towards Poles:** The separated chromatids, now individual chromosomes, are pulled towards the opposite poles of the cell by the spindle fibers. This ensures that each daughter cell will receive a complete set of chromosomes.

**Other Phases:**

- **Prophase:** This phase involves the condensation of chromatin into visible chromosomes, the breakdown of the nuclear envelope, and the formation of the mitotic spindle.

- **Metaphase:** During metaphase, the chromosomes align along the center of the cell, known as the metaphase plate. The spindle fibers attach to the centromeres of each chromosome.

- **Telophase:** In telophase, the separated chromatids (now chromosomes) arrive at the opposite poles and begin to decondense back into chromatin. The nuclear envelope starts to reform around each set of chromosomes, creating two distinct nuclei.

**Cytokinesis** follows mitosis and involves the division of the cell's cytoplasm and other organelles, ultimately producing two daughter cells.

In the diagram where chromatids are being pulled apart and moving towards the cell's opposite ends, it's indicative of **anaphase** of mitosis. This phase is crucial for ensuring that each daughter cell receives an identical set of genetic material.

Griffith performed an experiment on the mice to test two different strains of bacteria. One of them was virulent and the other was non virulent. The result depicted that the non virulent strain transformed into virulent strain through the process of transformation.

Explanation:

Different mice were injected with different combination of strains. One of the strain was a virulent one, III-S and the other one was II-R which was non virulent. Both the strains were taken from Streptococcus pneumoniae. The following observations were made:

1. In the first mice only simple III-S was introduced. The mouse died.

2. In the second one, heat killed III-S was injected. The mouse survived as the virulent portion was killed.

3. In this one II-R was introduced. Since it was an non virulent strain, the mice did not die.

4. In this he added both heat killed III-S and II-R. The mouse died and this perplexed Griffith. He wondered what had happened since the non virulent form and heat killed virulent form should have not harmed the mice.

Later he found out that the DNA of the Heat killed III-S was imbibed by the II-R form. The bacteria had 'transformed' and as a result the mice died.

Answer:

The effects of iron deficiency on cell culture growth, cell respiration, mitochondrial oxidative properties, and the electron transport chain were studied with suspension-cultured sycamore (Acer pseudoplatanus L.) cells. Iron deprivation considerably decreased the initial growth rates and limited the maximum density of the cells. Under these conditions, the cells remained swollen throughout their growth. The absence of iron led to a steady decline in the uncoupled rate of O2 consumption. When the uncoupled rate of O2 uptake closely approximated the respiratory rate, the cells began to collapse. At this stage, the level of all the cytochromes and electron paramagnetic resonance-detectable Fe-S clusters of the mitochondrial inner membrane were dramatically decreased. Nevertheless, it appeared from substrate oxidation measurements that this overall depletion in iron-containing components solely disturbed the functioning of complex II, whereas neither complexes I, III, or IV, nor the machinery involved in ATP synthesis, was apparently impaired in iron-deficient mitochondria. However, our results suggest that the impairment of complex II resulted in a strong reduction of the overall capacity of the mitochondrial electron transport chain, which was responsible for determining the rate of endogenous respiration in sycamore cells. Finally, this situation led to a depletion of various energy metabolites that could contribute to the premature cell death.

Explanation:

Iron levels are critical to the rate of cellular respiration due to their role in hemoglobin, myoglobin, and cytochromes, which are involved in oxygen transport and electron transfer. Abnormal iron metabolism, like anemia or iron overload, can lead to impaired cellular functioning and influence respiration efficiency. Maintaining proper iron levels supports optimal cellular respiration.

The effect of iron levels on the rate of cellular respiration is significant due to the role of iron in various biological processes. Iron is a critical component of hemoglobin, myoglobin, and cytochromes which are involved in oxygen transport and electron transfer within cells. Adequate iron levels are necessary for the efficient functioning of these proteins and hence, support optimal cellular respiration.

Abnormal iron metabolism, such as anemia or iron overload, can affect the cellular respiration rate. Low iron levels can lead to reduced oxygen transport to tissues, affecting ATP production during aerobic respiration. Conversely, iron overload can lead to oxidative stress and damage cellular components, impairing respiration efficiency. Moreover, in conditions like methemoglobinemia, where the iron in hemoglobin is oxidized from ferrous (Fe²⁺) to ferric (Fe³⁺), the oxygen-carrying capacity of hemoglobin is compromised, which can also impact cellular respiration.

Therefore, maintaining normal serum iron concentration and preventing abnormal deposition of iron in tissues are crucial for the proper function of cellular respiration pathways.

The similarly shaped bodies and fins of the shark and the dolphin are a result of convergent evolution and development of analogous structures.

Explanation:

The animals can differ a lot in their appearance, or look alike a lot, but very often the looks can be deceiving when it comes to determining their relations. In some cases, some animals differ greatly in their appearance, but they are much more closely related than some organisms that look very similar to one another. A nice example of animals that look alike a lot but are not closely related are the shark and the dolphin.

The shark and the dolphin have their common ancestors hundreds of millions of years ago, thus they are anything but closely related, with the shark being a fish, while the dolphin being a mammal. The resemblance in the appearance though has been a result of a convergent evolution, or rather trying to solve the same problems, in the same environment, in the same or similar manner. Because of it, analogous structures developed, making them look very similar.
