In every ecosystem, there are different organisms that interact with each other in a particular environment.  

The components of an ecosystem interact and interrelate with the ones that form part of another. Every ecosystem is related to another one.  

For example, in a food chain, a bird eats a fish, both animals belong to different ecosystems, but they are connected with each other.

In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted po
kifflom [539]

Answer:

The phenotypes are as follows

Purple, full- 9

Purple, constricted- 3

White, full- 3

White, constricted- 1

Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.

Explanation:

This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).

In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1

Purple color, full pod- 9

Purple color, constricted pod- 3

White flower, full pod- 3

White flower, constricted pod- 1

There are some structures that are common to all prokaryotic cells, and others that are only found in some bacterial species or
puteri [66]

Answer: Nucleiod, Ribosomes, flagella, fimbriae, plasma membrane

Explanation: A typical bacteria cell possess these structures mentioned above. nucleiod is a chromosome , a nucleic acid which can be DNA or RNA, It is the genetic material of cell which every bacteria cell must have. Flagella ensures swimming movement of all bacterial cell. Ribosome of bacteria cells ensures protein synthesis. Since all bacteria cells meet, plasma membrane is permeability barrier, location of enzyme and transports solutes. Fimbriae enables bacterial cells attachment to surfaces
