Answer: if a common plant is in an ecosystem becomes diseased the ecosystem may become unbalanced.
Explanation:
Answer:
A species of lizard is found on the eastern and western sides of part of a mountain range. On both sides, individual populations are small. On the western side, individual populations are relatively close together and males move extensively among populations to breed. On the eastern side, however, populations are farther apart and males seldom move among more than one or two adjacent populations to breed. If you were to study the genetic diversity of western and eastern populations, which pattern would you expect to find?
Each western population would be genetically diverse, although the allele frequencies might differ from one population to the next. Eastern populations would be less diverse, and some populations will have only a limited number of the total alleles available in the species.
Explanation:
Vascular tissue consists of xylem and phloem.
Explanation:
Vascular tissue could be a advanced conducting tissue, shaped of over one cell kind, found in vascular plants. the first parts of plant tissue are the vascular tissue and vascular tissue. These 2 tissues transport fluid and nutrients internally. The cells in plant tissue are generally long and slender
Phloem make up the vascular tissue. It helps in the transportation of the food prepared by the leaves of the plant.
Further Explanation:
Phloem is made up of vascular or livingtissue. It uses the turgor pressure that helps in the transportation of sugar to each part of the plants. It also supports the transportation of proteins and m RNA (messenger ribonucleic acid) to each region of the plants.
Phloem is composed of certain specialized cellssuch as sieve tubes, phloem fibers, companion cells and parenchyma cells. The phloem is divided into two types namely; primary phloem and secondary phloem. The primary phloem consists of the apical meristem. It is a region of new cell formation. It lies on the tip of root and shoot. It is further divided into two types; protophloem or metaphloem. The cell of Protophloem mature before elongation, whereas metaphloem mature after cell elongation. Secondary phloem resides in the plant that have a cambium.

Answer:
It means the way genes are expressed is the same in most organisms.
Explanation:
All living organisms use the same DNA or RNA as their genetic material. The manner in which the information in these genes are encoded or expressed is known as the GENETIC CODE. Genetic code comprises of all the codons that specifies amino acids in all living organisms. Only 20 amino acids in different sequential pattern makes up all proteins.
Nearly all living organisms use the same genetic code, as a codon does not specify a different amino acid in another organism. It is universal in all organisms that AUG codon specifies Methionine. Only slight differences to this pattern of genetic expression has been discovered, hence, the genetic code is said to be NEARLY UNIVERSAL.
The idea of a nearly universal genetic code refers to the common genetic 'language' shared by nearly all organisms. This means that, across an extraordinarily diverse array of species, the same sequences of DNA and RNA (the genetic code) translate to the same amino acids, which, in turn, build the same proteins. The universality of this code strongly suggests that all life shares a common origin.
The nearly universal genetic code refers to the fact that virtually all living organisms use the same codons, or sequences of DNA and RNA, to code for specific amino acids, which are the building blocks of proteins. This conservation of codons is seen across a vast array of species, with minor exceptions. For instance, if the mRNA encoding the globin protein in horses is transferred to a tulip cell, the tulip would synthesize the same protein, suggesting a common origin of all life on Earth.
The 64 possible combinations of triplet codons coding for 20 amino acids and with the occurrence of only one genetic code demonstrates the idea of degeneracy in the genetic code. This means that more than one codon can specify the same amino acid. For instance, unusual amino acids such as selenocysteine and pyrrolysine have been found in archaea and bacteria, which use unique codons.
Ultimately, the universality and degeneracy of the genetic code highlight the homologous characteristic shared by all species suggesting they share a common ancestor. This is powerful evidence for the shared biochemistry in all forms of life.

how do organisms with many cell types develop from a single cell
Answer:
A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs.During development, cells use both intrinsic, or inherited, information and extrinsic signals from neighbors to "decide on" their behavior and identity.
