Coevolution of plants and insects occur by : a.)either beneficial or antagonistic interactions that result in evolutionary change of both species.
How does coevolution of plants and insects occur?Many animals such as insects have adapted to feeding only on plants with particular defensive chemistry. If the plants have evolved secondary chemistry to avoid insects and insects evolved to handle the plant's chemistry then plant and insect coevolution has occurred
Many cases of coevolution has been found between plants and the insects. The process of reciprocal evolutionary change that occur between pairs of species or among groups of species as they interact with one another is known as Coevolution.

which of the statements describes the alimentary canal? the gastrointestinal tract and the organs of the digestive system the section of the digestive tract that is involved with absorption of nutrients the path that food travels from the stomach to the beginning of the large intestine the tubular passage through which food enters, is digested, and unused waste is excreted
The alimentary canal, commonly known as the digestive tract, as well as other organs like the pancreas and liver make up the digestive system.
The systems that food and fluids pass through on their way to being ingested, broken down, absorbed, and expelled as feces. The mouth, throat (throat), esophagus, stomachs, intestine, gastrointestinal tract, rectum, and anus are among these organs. The digestive system's four essential processes are motility, digesting, absorption, and secretion. From the mouth to the anus, the digestive system is known as the alimentary canal. The portion of it that consists of the gastrointestinal tract is known as the GI tract. Digestion and absorption are the two functions of the digestive system. Food is broken down into tiny molecules during digestion, and these molecules are subsequently absorbed by the body.

Explanation:
Gas cloud 1 is likely to form a star. Gas cloud 2 is not. Based on this information, match the given conditions with each cloud.
Its temperature stays well
below 14 million Kelvin.
Its volume shrinks and density
increases due to gravity.
It is spread out, with a greater volume and
lesser concentration of elements.
Its hydrogen atoms retain their electrons.
Its temperature surpasses
14 million Kelvin.
Its hydrogen atoms shed their electrons.
Gas cloud 1: It spreads with a larger area and a lower elemental concentration. Its temperature never rises above 14 million Kelvin. It has hydrogen atoms with electrons retained.
Gas cloud 2: As a result of gravity, its volume decreases and density rises. Its temperature is consistently above 14 million kelvin. The electrons in hydrogen atoms are lost.
As you are undoubtedly aware, stars develop amid gaseous clouds. Interstellar gases, primarily made of dust and hydrogen, are present in these clouds. Low temperatures cause gases to react, mix, and form molecules, which then produce clouds and continue to react until they eventually form stars.
Since Cloud 1 spreads with a higher volume and a smaller concentration of components, its temperature maintains far below 14 million Kelvin, and it contains hydrogen atoms that retain their electrons, these traits indicate that Cloud 1 will eventually create a star.
Given that cloud 2 won't produce stars, we can state the following about it: Due to gravity, its volume decreases and density rises, but its temperature remains above 14 million kelvin.

Explain the role of living things in the nitrogen cycle.
- 7th grade science
The role of Living Organisms is to convert the dead and decaying matter to ammonia(NH₃) in the nitrogen cycle.
Plants require nitrogen to make proteins DNA, RNA, ATP, etc. The nitrogen cycle is a process in which plants convert nitrogen into nitrates. This can be done by volcanic action, lightning, industrial activity, and by some bacteria.
These bacteria are the living organisms that use the plant as a carbohydrate source of energy and shelter and in turn, the plant uses the nitrate the bacteria produces for nitrogen fixation. The nitrates are then converted into plant and animal proteins, DNA and RNA.

One of the geological concepts that geologists employ to establish the relative ages of rock strata or layers, is the rule of superposition. According to this concept, layers of rock are overlaid or put down one on top of another. The oldest rock layers will be at the bottom, followed by the youngest.
Alternatively, the superposition rule is a fundamental concept of stratigraphy that states that within a succession of sedimentary rock layers, the oldest layer is at the bottom and the layers get increasingly younger with ascending order in the sequence.

In the cold temperature, when energy is less saturated phospholipids are organised in a compacted manner. On the contrary, the curved structures of the unsaturated fatty acid makes it difficult for them to come close to each other.
The phospholipid bilayer with unsaturated fatty acid has more flexibility and liquidity due to the existence of curves in the carbon chain.
The fatty acid design of the saturated phospholipid is straight whereas the unsaturated fatty acid is curved at distinct places in the carbon chain.

By laying eggs to reproduce, sea turtles are considered to be Oviparous.
An oviparous creature is one that produces eggs, and the youthful hatch after being ousted from the body. Whereas fertilization of the egg can happen inside or remotely, oviparous creatures continuously hatch the youthful outside of their body. Numerous creatures of land and water, winged creatures, fish, and reptiles are oviparous and regularly make homes to secure their eggs. This could be differentiated from ovoviviparous creatures, which hatch eggs interior of their bodies, at that point remove live young. This will be seen in a few sharks, snakes, and other animals. Being oviparous is a developmental procedure for generations. In this strategy, one or numerous eggs can be delivered. Each egg could be a gamete that has the female’s commitment to the hereditary material.
