Which characteristic of water makes it a universal solvent?
A. polarity
B. positive charge
C. bent shape
D. weak bonds

Answer:

In angiosperms, double fertilization takes place; one male gamete fuses with the egg cell to form the zygote and another male gamete fuses with the polar nuclei to form the endosperm. Various changes take place after fertilization. These include endosperm and embryo development, maturation of the ovules to form seeds and maturation of the ovary to give rise to a fruit. The zygote divides to give rise to two cells called as the terminal cell and basal cell.  The basal cell divides to form the suspensor which is a linear group of cells. The terminal cell divides to form the embryo. These embryo cells are further divided to form the different stages in the development phase. The first stage is the globular stage, followed by heart stage and finally the torpedo stage. This embryo develops and matures inside the seed.

Researchers can use this information to develop new therapies that target the specific genetic variation responsible for the disorder, potentially leading to more effective treatments and better outcomes for patients.

The causative variant refers to the specific genetic variation responsible for causing a particular trait or disorder.

In this case, the causative variant was linked to the c3 gene.

By combining the data from this family with studies of several other families, researchers were able to conclude that the c3 gene was associated with the development of a particular disorder.

The c3 gene is located on chromosome 19 and is responsible for encoding the complement component 3 protein.

This protein is part of the complement system, which is a complex series of proteins that play a crucial role in the immune system's defense against infection and disease.

The researchers identified a specific genetic variation within the c3 gene that was responsible for causing the disorder. This variation caused an alteration in the complement component 3 protein's structure and function, which in turn affected the immune system's ability to fight off infections and other diseases.

This conclusion was based on the analysis of genetic data from multiple families with similar disorders.

The identification of this causative variant has important implications for the diagnosis, treatment, and prevention of this disorder.

With this knowledge, healthcare providers can more accurately diagnose patients with this disorder and develop targeted treatment strategies.

Answer:

A good soil structure is important to allow air and water into the soil which are vital for healthy plant growth. It will improve drainage and reduce soil erosion caused by excess surface run-off. Without structure, soils will suffer from anaerobism, waterlogging and nutrient lock-up and, ultimately, plants will die!

Nectar is the adaptation of flowers resulting from the coevolution of plants and pollinators.

Nectar is a sweet liquid produced by flowers, which attracts pollinators, such as bees, butterflies, and hummingbirds. This is a prime example of coevolution, where plants and pollinators have developed a mutualistic relationship over time. The flowers provide the pollinators with nectar as a food source, while the pollinators assist the flowers in pollination, by transferring pollen from one flower to another.

Nectar plays a vital role in plant reproduction as it attracts pollinators, and as pollinators land on the flowers, pollen grains attach to their bodies, which are then transferred to other flowers as the pollinators move around. This helps in cross-pollination, which results in genetic diversity, and thus, healthier populations of plants.

The presence of nectar in flowers is an adaptation resulting from the coevolution of plants and pollinators, where the sweet liquid serves as an incentive for pollinators to visit the flowers, while ensuring the transfer of pollen between flowers.

In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.

A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.

Let the fixed charge for the first three days be x and the charge for each extra day be y.

From the given information, we can set up two equations:

For Saritha: \(\rm 3x + 4y = 27 -----(equation 1)\)  

For Susy: \(\rm 3x + 2y = 21 -----(equation 2)\)

We can solve for x and y by using elimination or substitution:

Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:

\(\rm 3x + 4y = 27\)

\(\rm - (6x + 4y = 42)\)

Solving above equations, we get:

\(\rm -3x = -15\)

\(\rm x = 5\)

Substituting x = 5 into one of the equations, we can solve for y:

\(\rm 3(5) + 4y = 27\)

\(\rm 15 + 4y = 27\)

\(\rm 4y = 12\)

\(\rm y = 3\)

Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

The recently discovered system that has been hypothesized to function as a bridge between the sensory and motor systems is called mirror neurons.

Mirror neurons are specialized neurons that are found in several regions of the brain, including the premotor cortex, the inferior parietal lobule, and the superior temporal sulcus. These neurons are activated both when an individual performs a particular action and when they observe another individual performing the same action.

The discovery of mirror neurons has led researchers to hypothesize that these neurons play a crucial role in social cognition and the ability to understand and empathize with others. Specifically, mirror neurons may allow individuals to simulate the actions and intentions of others, leading to the perception of others' emotions, intentions, and goals.

Mirror neurons have also been implicated in the development of language and speech, as well as in the ability to imitate and learn new behaviors. Dysfunction or damage to the mirror neuron system has been associated with a range of neurological and psychiatric disorders, such as autism spectrum disorders, schizophrenia, and depression.

Explanation:

organ system is two or more organs working together to perform a specialized function.

The correct option is C, A byproduct of breaking down glucose for energy that may cause burning in the muscle is lactic acid.

Lactic acid is a naturally occurring organic compound that plays a vital role in various biological processes. It is classified as an alpha hydroxy acid (AHA) due to its chemical structure. Lactic acid is produced through a process called anaerobic glycolysis, where glucose is metabolized without the presence of oxygen. This occurs in various organisms, including humans, during intense exercise when oxygen demand exceeds supply.

In the human body, lactic acid is primarily found in muscles and blood. It serves as an energy source and helps regulate the pH balance. During vigorous exercise, the production of lactic acid increases, leading to the familiar sensation of muscle fatigue and soreness. Lactic acid is also used in various industries. In the food industry, it acts as a preservative, flavoring agent, and pH regulator. It is a key ingredient in the production of sourdough bread, yogurt, and cheese.

The answer is that the reclassification of segmented worms and roundworms into two separate clades was based on molecular phylogenetics

A scientific approach that analyzes DNA and protein sequences to infer evolutionary relationships between organisms. Through this analysis, it was determined that segmented worms (annelids) and roundworms (nematodes) belong to different clades, despite their similar morphological characteristics. This reclassification helps to refine our understanding of the evolutionary relationships between different groups of animals.

Molecular phylogenetics is a technique that involves analyzing the genetic material (DNA or RNA sequences) of organisms to determine their evolutionary relationships. In the case of segmented worms (Annelida) and roundworms (Nematoda), scientists compared their genetic sequences and discovered significant differences that warranted their separation into two distinct clades. This reclassification was based on the genetic evidence rather than their morphological similarities, providing a more accurate representation of their evolutionary history.
