Answer:

A food chain is a linear flow of energy and nutrients from one organisim to another .

A food web can be termed as the combination of many different food chains and the relationship that exists between each organisim

For instance :

Answer:

An aponeurosis is functionally similar to a tendon because, like a tendon, it is connective tissue that attaches muscles to bones.

Explanation:

It is a process by which the plants prepare glucose by using sunlight

Answer: First, gravity is the force that pulls us to the surface of the Earth, keeps the planets in orbit around the Sun and causes the formation of planets, stars and galaxies. ... The Strong Nuclear Force binds the nucleus of an atom together.

This is because mitochondria produce ATP during aerobic respiration and ATP is needed for muscle to contract. Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.

Answer:

The water cycle shows the continuous movement of water within the Earth and atmosphere. ... Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).

Answer:

Hello! Today I will tell you somethings about water hyacinth, we will start with what does it do? Well,

Water hyacinth has a variety of negative impacts once introduced into a freshwater environment. it forms dense, impenetrable mats which clog waterways, making boating, fishing and almost all other water activities, impossible. It also reduces biodiversity by crowding out native plants at the water's surface and below.

Well that makes it seem bad is it?

Answer:

Photosynthesis occurs in plants;cellular respiration occurs in animals

Answer:

Internal forces are those forces which exert on each other when the bodies are part of the system. The forces acting between the atoms of molecules that keep them together are example of internal force.

Explanation:

Answer:

C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.

Explanation:

Answer:

Mitosis:

A single division occurs, separating sister chromatids

End result is two diploid cells that are genetically identical to each other and the parent cell

Meiosis:

The first division separates homologous pairs; the second division separates sister chromatids

Homologous chromosomes pair up and form chiasmata

Homologous pairs of chromosomes line up on the metaphase plate

Daughter cells contain recombinant chromosomes

End result is four haploid cells that are genetically different from each other and the parent cell  

Mitosis and Meiosis:

Chromosomes duplicate during interphase

Process starts with a diploid cell

Duplicated chromosomes line up Individually on the metaphase plate in a diploid cell

Explanation:

Mitosis is the division of vegetative cells while meiosis involves the division of sex cells. Both divisions start with diploid parental cells but while the daughter cells in mitosis are also diploid, those of meiosis are haploid. This is why mitosis is referred to as equational division while meiosis is known as reductional division.

A cell that will undergo mitosis or meiosis would first have its genetic materials duplicated during interphase in addition to the synthesis of other important biochemicals such as proteins. Mitosis involves just a single division of the sister chromatids with two genetically identical daughter cells who are also clones of the parent cells resulting.  

Meiosis, on the other hand, involves two divisions - the first one happens to separate homologous chromosome pairs while the second division separates sister chromatids just like in mitosis.  During the early stage of meiosis, homologous chromosomes synapsed through the formation of a synaptonemal complex to form tetrads. Thereafter, synapsed chromosomes exchange chromosomal segments at a point known as chiasmata. All these happen at the prophase stage of meiosis I. The paired homologous chromosomes are then lined up at metaphase where they are engaged by the spindle fibers.

Meiosis II and mitosis are more or less the same with the chromosomes condensing at the prophase and the formation of metaphase plates at the metaphase. Sister chromatids are pulled apart and they migrate to the opposite poles at the anaphase and telophase.Explanation:

Answer: Glucose (and also oxygen)

Explanation: Photosynthesis is the process of turning CO2 and H2O in Glucose and oxygen where the chloroplasts use the energy from the sun to rip apart the molecules and rearrange them into glucose, a useable form of energy, and oxygen, a bi product that gets released into the atmosphere.

Answer:

Taiga ,temperate grassland

Temperate grasslands are important biomes characterized by their fertility.  The correct option is C. Temperate grassland are flat inland areas, rich and fertile due to the constant replenishing of nutrients from decomposing grasses.

Answer:

Dew is atmospheric moisture condensing on colder surfaces, and is pure water. Guttation is moisture secreted from within the plant itself, and contains xylem sap. Guttation allows for secretion through the edges of the plant.

Answer:

1. Air plants are part of the Bromeliad family, air plants are epiphytes — plants that attach themselves to other plants for support, without relying on the host to thrive.

2. They absorb moisture and nutrients through their leaves, not their roots, which they use only to anchor themselves to other plants or objects. Since air plants don't absorb their nutrients through their roots, they can't be planted in the soil.

3. The internal structure and anatomy of Tillandsia have adapted to survive on varied hosts both alive and not. Their leaves are able to pull moisture from the air more efficiently while some have developed a camel-like ability to store water and survive in areas prone to drought. Being up in trees or on rocky cliffs protects these plants from damage done by foraging animals, flooding or erosion on the ground.

Explanation:

Epiphytic plants can be used to determine the elemental composition of the air and soil in which they grow, cycle nitrogen, affect water retention within the rainforest, and house many resources for various plants and animals.

Through the analysis of epiphytes, biologists can determine changes in air and soil composition over time. Air pollution in the rainforest can be monitored by the use of air plants.  By monitoring how mosses and lichens respond to different air pollutants, especially heavy metals, the effect that the toxins have on the environment can be determined In the rainforest, epiphytes can be placed in areas where there is ecological damage to determine if nearby pollutants are affecting the health of the forest and additionally play a role in nitrogen cycling.

Answer:

Although 3 and 4 are great answers, I honestly think the answer is C. Because you can simply define the cell wall as a semi-rigid thick protective structure that surrounds the cell membrane of some types of cells for protection and defining the shape of the cell. The cell membrane alone cannot provide the required rigidity or strength. All living organisms are composed of cells. Cell walls contain only little amount of protein in the cell wall.

Explanation:

Not all cells have a cell wall; the cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Cell walls are found in both prokaryotes and eukaryotes, although not all cells have cell walls. Animal cells does not have a cell wall; Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food.
