Answer:

The primary spermatocyte of prophase 1 contain double amount of DNA (3.57×2= 7.14pg) as it is diploid in nature.

Explanation:

Most DNA in mature human sperm is bound to protamine, as somatic histones are replaced during spermiogenesis. However, biochemical analyses of human sperm proteins indicate retention of some histones resulting in a nuclear protein composition that is about 90% protamine and 10% histone.

Primary spermatocyte produces four spermatids. During spermatogenesis there are two cellular divisions, but only one replication of DNA so that each spermatid has 23 chromosomes (haploid), one from each pair in the original primary spermatocyte. It begins with a diploid spermatogonium in the seminiferous tubules, which divides mitotically to produce two diploid primary spermatocytes.

Explanation:

The brain function that is likely to be affected is the facial recognition.

Stroke is defined as a medical emergency that affects the cerebrovascular system whereby a blood vessel in the brain is blocked thereby reducing the blood flow to that particular part of the brain.

The right temporal lobe of the brain is responsible for learning and memorizing non-verbal information, recognizing information, and determining facial expressions.

Therefore, a stroke that affects the right temporal lobe of the brain is likely to affect the ability of the individual to be able to facially recognise another person.

The high-energy phosphate bonds present in ATP contribute to its ability to act as an energy currency.

The structure that contributes to the ability to act as energy currency is the presence of phosphate bonds. The full form of ATP is Adenosine Triphosphate. As the name suggests, this molecule contains three phosphate groups.

The other component of ATP is adenosine, which is a nitrogenous base. It forms a bond with phosphate groups and sugar to give ATP.

The structure of ATP is shown in the adjoining image.

The bond formed between the phosphate groups is known as the phosphodiester bond. This bond is very strong and produces a large amount of energy when broken.

Whenever the cell needs the energy to do any work, these bonds are readily broken to release a large amount of energy.

Thus, the high-energy phosphate bonds present in ATP contribute to its ability to act as an energy currency.

For energy to be released from ATP,  a phosphate group is broken from the molecule to form ADP.  Therefore option (D) is the correct answer.

Adenosine triphosphate, also known as ATP ,the primary energy currency of cells.

ATP is an RNA nucleotide with a chain of three phosphates, according to its structural makeup. Adenine, a nitrogenous base, a chain of three phosphates, and ribose, a five-carbon sugar, are all joined together in the heart of the molecule.

The three phosphate groups are identified as alpha, beta, and gamma, according on how close to the ribose sugar they are. Phosphonhydride bonds, often known as "high-energy" bonds, are the bonds that connect the phosphate groups.

In  hydrolysis (water-mediated breakdown) reaction, one of these bonds is broken, releasing a sizable quantity of energy.

Answer: Primary producer > primary consumer > secondary consumer > tertionary consumer.

Explanation: Primary producers(plants) get their energy from the sun then when a primary consumer (organism that eats plants; herbivores) eats the primary producer it collects that energy with it. Then when the primary producer is eaten by the secondary producer( carnivores that eat smaller animals; such as wolves,crow,hawks etc.). The tertionary consumer eats the secondary consumer.(tertionary consumers are larger carnivores) therefore energy gets passed down the line all the way to the tertionary consumer.

Answer: The energy flow is unidirectional in nature.

Explanation: When these herbivores are ingested by carnivores of the first order (secondary consumers) further degradation will occur. Finally, when tertiary consumers consume the carnivores, energy will again be degraded. Moreover, in a food chain, the energy flow follows the 10 percent law.

The benefit that oil never wear out is that it can be used again and again.

The term oil refers to that which could be used to prevent wear and tear. We know that friction is the force that opposes the motion of one surface on another. Thus anytime that two surfaces are in contact, we notice that the force of friction comes into play. The phenomenon of friction is the reason behind the wear and tear that is experienced when we are using the various parts of a machine that involves the movement of one part of the machine on top of another.

Having said all these, oil is the substances that is most commonly used to prevent the phenomenon of friction. We could be able to use the oil again and again.

Answer:

The global economy recycles less than 10 percent of materials; about 50 percent of processed materials are used to provide energy and are thus not available for recycling. It is simple: economic growth is not compatible with environmental sustainability.

Explanation:

Sustainability Is Not Only Compatible With Growth, It Requires It – But Only With Targeted Innovation. Opinions expressed by Forbes Contributors are their own.

Economic growth is closely linked to increasing production, consumption and resource use, which has negative effects on nature, climate and human health. Moreover, current research suggests that it is unlikely that economic growth can be completely detached from its environmental impacts, the EEA briefing notes.

Economic growth will be undermined without adequate environmental safeguards, and environmental protection will fail without economic growth. The earth's natural resources place limits on economic growth. These limits vary with the extent of resource substitution, technical progress, and structural changes.

True. On one side of the membrane, carrier proteins bind to molecules or ions and release them on the opposite side.

Channel proteins are found in membranes surrounding cells or organelles. Cells use many different molecules that need to cross the membrane for internal use or be exported to the extracellular space. Some small, non-polar molecules can cross membranes directly, whereas larger or charged molecules must use specialized proteins or endo/exocytosis to enter and exit.

Channel proteins allow these molecules to enter and exit cells, usually without expending energy. Examples include aquaporins, which allow polar water molecules to penetrate. Another example plays an important role in cell communication. Ligand-gated ion channel. In order for these channel proteins to open, they need a binding ligand (ligands are molecules that act as the "key" for the channel protein). The presence of a ligand signals the protein to open, making it easier for molecules to pass through.

The mechanisms of metastasizing breast cancer are complex. the goal was to identify tumor-induced stromal modifications that affect metastatic cell behavior, and function as better marks for therapy.

Dual-species gene expression analysis was performed to  identify stromal changes in cancer-bearing tissue for three different metastatic Breast cancer  xenografts. In pre-clinical models of Breast cancer, the systemic need for S100A8+ myeloid cells-including myeloid-derived suppressor cells (MDSCs)-was stimulated by tumor-derived factors.The need for S100A8+ myeloid cells was reduced by inhibition of tumor-derived factors leading to fewer metastases and fewer primary tumors. Those myeloid-derived suppressor cells possess the ability to suppress T cell accumulation upon co-culture.

The release of macrophage inhibitory factors activates the need for S100A8+ myeloid cells systemically. Inhibition of MIF leads to delays in lower metastatic burden and tumor growth. In enhancing cancer progression independent of their suppressive activity on T cells,  there is the recruitment of S100A8+ myeloid cells to secondary sites in xenograft models and primary tumors of Breast cancer.

The discussion of pharmacokinetics of exogenous melatonin in relation to formulation, and effects on sleep: a systematic review is given in the paragraph below:

Evidence on the clinical effectiveness of exogenous melatonin for the treatment of sleep disorders is inconclusive. This might be as a result of variations in the melatonin formulations' pharmacokinetic (PK) properties that were employed in clinical trials.

This systematic review's goal was to comprehend the connection between melatonin formulations and PK parameters as well as, to the extent possible, the effects on sleep outcomes. We conducted a systematic review to achieve this goal, and 19 papers were included. Three melatonin transdermal formulations, thirteen oral formulations, one topical, two buccal, two intravenous, and two nasogastric formulations were all included in the research. Six of the seven studies that looked at how the melatonin formulation affected sleep revealed a significant improvement in one or more sleep metrics.

The possibility of a more effective controlled release formulation that postpones maximum concentration (Cmax) was found. Different formulations and doses have an impact on melatonin PK, which raises the possibility that therapy effectiveness may be impacted. Based on the available data, we are unable to propose particular melatonin formulations and PK values for particular sleep disorders. Future research should methodically examine the effects of various melatonin formulation PK parameters on the effectiveness of treating sleep disorders and circadian disorders.

Natural substances like melatonin are present in both plants and animals. It is mostly recognized in animals as a hormone secreted at night by the pineal gland in the brain, and it has long been linked to the regulation of the sleep-wake cycle.
