Answer 2

Answer:

The answer is Mouth

Explanation:

The digestive system is the set of organs responsible for the feeding process. The organs that make up the gastrointestinal tract are the mouth, the esophagus, the stomach, the liver, the pancreas, the gallbladder, the small intestine, the large intestine and the anus. The digestive system begins in the mouth where the food that enters, is chewed and the digestive juice known as saliva is added.

what conditions are required for a hurricane to form

Answers

- The storm must be developing over warm water. The water must be at least 80 degrees Fahrenheit. The warm water provides the energy for increased evaporation of water from the ocean surface. 

- The warm water must be at least 200 feet deep

- There should be very little wind shear in the area. Wind shear occurs when there is a difference in wind speed and direction over a short distance. Strong wind shear can stop the formation of hurricane eye walls.

how you can tell if the couple who is married had children?

Answers

Final answer:

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.

Explanation:

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.

Crustal plates scrape and slide past each other along faults at their boundaries. For example, the Pacific and North American Plates slide past each other along the San Andreas Fault in northern California.

What natural hazard usually results when crustal plates scrape and slide past one another?
A.
hurricanes
B.
tsunamis
C.
tornadoes
D.
earthquakes

Answers

the answer is earthquakes

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.

Which biological process involves the conversion of one type of chemical energy into another type of chemical energy? photosynthesis active transport cellular respiration transpiration

Answers

Why is photosynthesis considered a
bridge between the nonliving and living
worlds?

Answers

It converts light energy which is abiotic, to glucose, which is consumed by organisms for energy. (It transfers to the appropriate type of energy for biotic organisms)

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.

How does Rosalind franklin deal with Watson and crick taking the credit for the structure of DNA

Answers

She doesn't. Rosalind Franklin died shortly after, due to cancer from the radiation used in her x ray experiments with DNA.
Final answer:

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.

Explanation:

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.

Who named the Lily Pad and what does it mean?
Who named the cat and what does it mean?

Answers

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.

hope it helps sorry I do not know the cat one

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.
