Why is food web more practical in nature than food chain
Answers
Answer:
Hey mate.....
Explanation:
This is ur answer....
A food web is a more realistic way of portraying an ecosystem than a food chain because food chains imply that organisms only eat one type of organism which is rarely true. In a food chain predators occupy higher levels than their prey. Food webs are more complicated diagrams that are not purely linear.

The potential organism was derived from plant cell, animal cell and fungal cell.
Cell nucleus
The cell nucleus is the largest organelle found in the cytoplasm and it is present only in eukaryotic cells. It is in the nucleus that the chromosomes carrying the genes responsible for controlling cellular activities are found.
Whit this information, we can conclude that the potential organism was derived from plant cell, animal cell and fungal cell.

The ancestors of modern-day fish were vertebrate chordates. Vertebrate chordates are believed to have evolved from invertebrate chordates, which were similar to modern-day tunicates.
What change must have occurred during the evolution from invertebrate chordates to vertebrate chordates?
A.
A backbone evolved to enclose the notochord, which develops from the spinal cord.
B.
An endoskeleton evolved to enclose the spinal cord, which develops from the notochord.
C.
An endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.
D.
A backbone evolved to enclose the spinal cord, which develops from the dorsal nerve cord.
Answers
Answer:
The correct answer is option B, that is, an endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.
Explanation:
It has been discovered that the ancestors of the modern-day fish were vertebrate chordates. The vertebrate chordates are considered to have evolved from the invertebrate chordates that are identical to the present day tunicates. It has been found that in vertebrates the endoskeleton has evolved to encompass the dorsal nerve cord that has been developed from the notochord (a characteristic of invertebrates).

how does the cell make proteins inside the ribosome?
Answers
Answer:When the cell needs to make a protein, mRNA is created in the nucleus. The mRNA is then sent out of the nucleus and to the ribosomes. When it is time to make the protein, the two subunits come together and combine with the mRNA. The subunits lock onto the mRNA and start the protein synthesis.
At a ribosome, an intercellular structure made of both RNA and protein, the process of making proteins occurs in a cell. The messenger RNA sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.
What are proteins?Proteins are defined as a macro- and large-scale biomolecules that contain one or more long chains of residues from the amino acid.
It is also defined as the results of the process of decoding, which begins with information in cellular DNA.
A protein is a biomolecule made up of peptide bonds that connect the amino acid residues in it.
There are seven types of proteins.

Which of the following sentences state a significant conclusion that Gregor Mendel drew from his experiments with pea plants? Traits are inherited in discrete units and are not the result of "blending." Genes are composed of DNA. Recessive genes occur more frequently in the F1 generation than do dominant ones. There is considerable genetic variation in garden peas.
Answers
Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."
------------------------
After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.
Mendel named dominant the expressed variant.
Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.
He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.
Mendel named recessive the second alternative variant.
Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.
These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors separated again during sex cells formation, producing two types of gametes, each with only one factor.Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.
He thought that alleles separate -segregate- during the process of gamete formation.
The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.

The cell in the diagram is a plant cell because it has chloroplasts and a cell wall.
There are two types of cells animal cells, which are the ones that humans and animals have, and plant cells, which are the ones that plants and trees have. They share some organelles, but they also have some that are specific to each type.
The plant cell parts in the picture are:
Rough Endoplasmic Reticulum: it is where the ribosomes are. The synthesis of proteins happens there.Chloroplast: it is an organelle-specific of plant cells. They are in charge of photosynthesis.Cell wall: it is only present in plant cells. It surrounds the membrane.Mitochondria: It is the place that generates the energy that the cell needs.Vacuole: they are bigger in cell plants than in animal plants. It has many functions, but one is to store water.Membrane: it draws the limits of the cell.Golgi Apparatus: it is the place where proteins go to be distributed.Nucleus: it contains DNA, and it has a membrane around it.The nucleolus: is the larger part of the nucleus. It is in contact with the endoplasmic reticulum.To sum up, the plant cell has a bigger vacuole than the animal cell; it also has chloroplasts and a cell wall, which are not present in the animal cell.

Describe the structure and bonding of gold
Answers
Answer:
structure
The arrangement of atoms in gold follows what's called a "face centred cubic" (fcc) structure. Put simply, the atoms in gold form cubes, with an atom at each of the corners, and another atom in the centre of each of the faces (you can see what this looks like in the image below).
bonding
Silver, iron, platinum, gold, and copper all form metallic bonds. Unlike covalent bonding, metallic bonding is non-directional. The strong bond consists of positively charged metal atoms in fixed positions, surrounded by delocalized electrons.
Explanation:
Gold's atoms are face-centered cubic (fcc) and has metallic bonding in it's structure.
What is the bonding and structure of gold?Because a cloud of electrons holds the atomic nuclei of gold together, gold is soft. Instead of having a set of electrons allocated to one nucleus, this cloud floats through the gold framework. Metallic bonds are the forces that exist between the nuclei and the electron cloud.
In gold, atoms are arranged in a configuration known as a "face-centered cubic" (fcc) structure. Simply put, the gold's atoms take the shape of cubes with one at each of their four corners and another in the middle of each of their six faces.
