Fraternal twins (dizygotic) result from the fertilization of two separate eggs (ovum).

Fraternal twins, also known as dizygotic twins, occur when two separate eggs are fertilized by two different sperm. Each egg is released from the ovaries and is independently fertilized, resulting in the development of two distinct embryos.

In the process of ovulation, typically, a single egg is released from one ovary during each menstrual cycle. However, in the case of fraternal twins, two eggs are released and fertilized by two different sperm, leading to the development of two embryos. These embryos can develop simultaneously in the womb and may or may not share the same placenta or amniotic sac.

Unlike identical twins (monozygotic), who develop from a single fertilized egg that splits into two embryos, fraternal twins are genetically similar to siblings born at different times. Each twin in a fraternal twin pair shares, on average, 50% of their genetic material, just like any other siblings.

Overall, fraternal twins result from the fertilization of two separate eggs, leading to the development of two genetically distinct individuals.

Explanation:

Option D the active genes in the cell determines the function of a specialized cell.

The relationship between cell specialization and gene expression is that the expression of specific genes is what enables a cell to become specialized. Cell specialization is the result of the expression of certain genes that control the development, function, and maintenance of the cell's specialized characteristics.

Therefore, with this data, we can see that gene expression in a cell will determine its specialization such as for example, a muscle cell will have a different gene expression profile than a skin cell.

Answer:substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.

Explanation:Enzymes and substrates share specificity in that an enzyme will only react with a specific substrate • This is because the active site is complementary in both shape and charge to a given substrate • The model by which this is known is ‘lock and key’ as the substrate is a precise structural fit for the enzyme, much like a lock and key • When the enzyme and substrate bind, they form an enzyme-substrate complex, before the substrate is catalytically converted into a product

If we trigger activity in the lateral hypothalamus of a rat by stimulating it electronically, it will typically result in increased food intake and drinking.

The lateral hypothalamus is a region of the brain that plays a critical role in regulating feeding behavior and fluid balance. Electrical stimulation of the lateral hypothalamus has been shown to trigger a cascade of neural and hormonal signals that increase appetite and thirst in animals. This area of the brain is also associated with other important functions, such as the regulation of sleep-wake cycles, stress response, and reward processing. Dysfunction of the lateral hypothalamus has been linked to various neurological and psychiatric disorders, including obesity, narcolepsy, and addiction.

The correct answer to the question is c) Carbon dioxide uptake is reduced by the stomata closing to prevent excessive water loss. During a hot and dry summer, plants tend to lose a lot of water through transpiration, which is the process of water evaporating from the leaves.

In order to conserve water, plants close their stomata, which are small openings on the leaves that allow for gas exchange. When stomata are closed, the amount of carbon dioxide that enters the plant is reduced, which can limit the plant's ability to carry out photosynthesis and produce energy.

This reduction in photosynthesis can result in lower crop yields. While it is true that stomata can also stay open to help cool the leaves, this is not the main reason for reduced crop yields during a hot and dry summer. It is also not true that too much carbon dioxide enters the plants when stomata are wide open or that oxygen uptake is reduced by the stomata closing to prevent excessive water loss. Hence, c is the correct option.

Explanation:

Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA

depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity

Schizophrenia is a serious mental disorder that affects how a person thinks, feels, and behaves. It is characterized by a combination of psychotic symptoms, including delusions, hallucinations, disordered thinking, and abnormal behaviors. These symptoms can be chronic or episodic, and can vary in severity and duration. Schizophrenia typically emerges in early adulthood, and is more common in men than in women.

The exact causes of schizophrenia are not fully understood, but research suggests that a combination of genetic, environmental, and neurochemical factors may contribute to its development. Diagnosis of schizophrenia is based on clinical assessment of symptoms, and treatment typically involves a combination of antipsychotic medications and psychosocial interventions, such as cognitive-behavioral therapy and family therapy. With appropriate treatment, many individuals with schizophrenia can manage their symptoms and lead fulfilling lives, but the disorder can be challenging to treat, and some individuals may require ongoing support and care.

Fertilizer runoff is rich in nutrients such as nitrogen and phosphorus, which causes an increase in the dissolved nutrient levels in aquatic ecosystems which causes an increase in the amount of phytoplankton.

Thus, these nutrients act as a fertilizer, which results in the rapid growth of phytoplankton, and their population size gets doubled. This leads to an increase in the population of primary consumers such as zooplankton and small fish that feed on them in aquatic ecosystems.

However, if the phytoplankton population grows too large, algae and other aquatic plants also increase in aquatic ecosystems, which leads to oxygen depletion and harmful algal blooms, thereby, disrupting the entire ecosystem.

The energetic cost of converting lactate back to glucose per molecule of glucose generated is 6 ATPs.

Lactate is produced by anaerobic respiration in muscles when oxygen demand exceeds supply, causing fatigue. The liver converts the lactate back to glucose, which muscles can utilize for further energy production. There are two main pathways that produce ATP in human cells: aerobic respiration (requiring oxygen) and anaerobic respiration (not requiring oxygen).

During anaerobic respiration, energy is obtained from glucose without the use of oxygen. As a result of anaerobic metabolism, red blood cells generate lactate. Red blood cells are the only mammalian cells that lack mitochondria and consequently depend solely on anaerobic metabolism for energy production. This reliance on anaerobic metabolism has significant consequences, with lactate being continually produced as a byproduct.

The liver is responsible for converting lactate back to glucose in a process known as gluconeogenesis. It is an ATP-intensive process that consumes 6 ATP molecules per molecule of glucose generated, according to research.

Certain human do impact estuaries

The flow of water through an estuary can be affected by several factors, including:

Tidal cycles: Estuaries are affected by tidal cycles, which can cause significant fluctuations in water levels and flow rates. The ebb and flow of the tides can cause strong currents and create turbulence in the water.

River discharge: The amount of water flowing into the estuary from upstream rivers can have a significant impact on the flow of water in the estuary. During periods of heavy rainfall or snowmelt, river discharge can increase, causing a surge of freshwater to flow into the estuary and push back the seawater. Conversely, during periods of low rainfall, river discharge may decrease, leading to a lower flow of freshwater into the estuary.

Wind: Strong winds can cause surface currents and waves, which can affect the flow of water in the estuary. Wind can also influence the distribution of sediment and nutrients in the water.

Salinity gradients: Estuaries are characterized by gradients in salinity, with seawater at the mouth of the estuary and freshwater from upstream rivers at the head of the estuary. These gradients can influence the flow of water, as freshwater will tend to flow downstream toward the seawater.

Topography: The topography of the estuary, including its shape, depth, and width, can influence the flow of water. Narrow channels and deep channels can create stronger currents, while shallow areas can cause turbulence and slow the flow of water.
