Nymphaeaceae /ˌnɪmfiːˈeɪsiː/ is a family of flowering plants, commonly called water lilies. They live as rhizomatous aquatic herbs in temperate and tropical climates around the world. The family contains five genera with about 70 known species.[2] Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or emergent from the surface. Leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria and Euryale. It is the national flower of Bangladesh.[citation needed]

Water lilies are a well studied clade of plants because their large flowers with multiple unspecialized parts were initially considered to represent the floral pattern of the earliest flowering plants, and later genetic studies confirmed their evolutionary position as basal angiosperms. Analyses of floral morphology and molecular characteristics and comparisons with a sister taxon, the family Cabombaceae, indicate, however, that the flowers of extant water lilies with the most floral parts are more derived than the genera with fewer floral parts.[clarification needed] Genera with more floral parts, Nuphar, Nymphaea, Victoria, have a beetle pollination syndrome, while genera with fewer parts are pollinated by flies or bees, or are self- or wind-pollinated.[3] Thus, the large number of relatively unspecialized floral organs in theNymphaeaceae is not an ancestral condition for the clade.

Final answer:

The Lily Pad got its name from its round, flat leaves that resemble a pad or cushion. The word 'cat' has its origins in Old English and refers to the domesticated feline species.

Explanation:

The Lily Pad: The name 'lily pad' originated from the physical appearance of these aquatic plants. Their round, flat leaves resemble the shape of a pad or cushion, which is why they are called 'lily pads'. These plants are typically found in still or slow-moving water, such as ponds or lakes.

The Cat: The name 'cat' comes from the Old English word 'catt', which dates back to the late 8th century. It is believed to be derived from the Late Latin word 'cattus' and the African wildcat 'felis lybica'. 'Cat' refers to the domesticated feline species, commonly kept as pets.

In a dictionary, the word 'mark' would not be present on a page with the guide words 'manage' and 'massive' as it does not fit alphabetically between the two.

The guide words on a dictionary page give you the first and last word on that page. Therefore, any word that fits alphabetically between the two guide words should be on that page. Looking at the guide words 'manage' and 'massive', all words beginning with 'ma-' and alphabetical order between 'manage' and 'massive' will be included. Thus, the word that will NOT be on the page is 'mark'.

Tropical rainforests are found in the world’s hottest and wettest areas, namely those closest to the equator. The world’s largest tropical rainforests are in Amazon basin in South America, lowland regions in Africa, and the islands off of Southeast Asia. While they are found in abundant in Sumatra and New Guinea, small areas are also found in Central America and parts of Australia.

Answer:

The process of photosynthesis is considered as a bridge between the non living and living world because the substrate which is used in this process is non living and the plants that convert this into useful product is a living thing.

The carbohydrates that is produced by the plants body is used by the plants and animals which is also living thing.

The oxygen which is produced as a by-product is also used by the plant and animals and they are also living components of life.

Hence, it acts as a bridge between the living and non living components of life.

The presence of children in a married couple's life can be indicated by societal norms and changes in the couple's lives. In ancient Rome, not having children could lead to divorce, whereas in modern society, stress and changes after the birth of the first child can affect the marriage. In the United States, the presence of children is often considered a key aspect of a family.

The presence of children in a married couple's life can be determined through various factors and societal norms. For example, in ancient Rome, having children was considered important for being a good citizen. If a couple was unable to have children, they would sometimes have others step in to father the child for them. In modern society, the presence of children can be indicated by the stress and changes that occur after the birth of the first child, as well as by the decline in marital satisfaction over time. Additionally, in the United States, the presence of children is often seen as a key indicator of a family.

Rosalind Franklin, through her work with X-ray diffraction images, significantly contributed to the understanding of DNA structure. Watson and Crick used her data in their discovery, receiving a Nobel Prize which Franklin, already deceased, did not share.

British chemist Rosalind Franklin made significant contributions to the discovery of the structure of DNA. Her work in measuring X-ray diffraction images of DNA provided crucial information, specifically the concept of 'A' and 'B' forms of DNA. However, the recognition she deserved was largely taken by James Watson and Francis Crick, who used her data to confirm that DNA forms a double helix.

James Watson, Francis Crick, and Maurice Wilkins were awarded the Nobel Prize in Physiology or Medicine in 1962 for this discovery. Unfortunately, Rosalind Franklin had died by then, and Nobel prizes were not awarded posthumously. Despite this, her contribution to the discovery remains invaluable and fundamental to our understanding of DNA structure.

Answer:

Earthquaques

Explanation:

Crustal plates are extremely heavy and thus impose tremendous pressure on adjacent plates, however they don't immediately slide past each other. Rather, tension is built up as time progresses and the pressure continues, until it is released and the plates slide rather abruptly to find their new position. The process starts over again because the plates do not stop moving. The internal heat in the core of the planet fuels their movement.

B, Field study. This is because she wants to find a number in a certain location that cannot be replicated. She needs to observe the amount of species so an Experiment does not work. A survey is a questionnaire and wouldn't help because she needs to see it herself. A lab study wouldn't replicate the rocky shores she needs to investigate.

Grace should perform a field study to observe and record the different organisms living in natural tide pools. This observational study is the best method for understanding the biodiversity of such ecosystems without altering their natural state, option B is correct.

Grace is interested in finding out how many kinds of organisms live in tide pools on a certain rocky shore. Conducting a field study would be the most appropriate method for her to investigate the biodiversity of tide pools. This method involves observing organisms in their natural environment, which allows for real-world interactions and behaviors to be recorded and is best suited for studying ecosystems.

Option B, a field study, provides an observational study approach that would enable Grace to gather data on different organisms directly from the site. A survey could also be utilized as part of the field study to systematically record the presence and variety of organisms. This hands-on approach is more effective for ecological research than controlled experiments or laboratory studies because it does not manipulate variables but observes them as they occur naturally.

Other methods such as experiments or lab studies are less suitable because they often involve controlled conditions that do not accurately reflect the complex and dynamic interactions found in a tide pool ecosystem.
