Answer:

A. outside plasma membrane:

1. cell wall 6. flagella

B. outside of the cell

4. fimbriae 5. pilus

C. in cytoplasm

2. nucleoid 3. ribosome

Explanation:

Bacteria is one of the three domains of cellular organisms. Bacteria are prokaryotes, cells that lack a true nucleus and membrane-bound organelle.

The plasma membrane is the outer membrane that enclosed the cytoplasm and cytoplasmic substance. The cell wall is covering the present out of the cell membrane or plasma membrane. Flagella are attached to the plasma membrane but it is present outside of the plasma membrane.

Fimbriae and pilus are the structure present outside of the cell wall and help to attach it to other cells or any surface. Nucleoid and ribosomes are present in the cytoplasm of the bacterial cell.

) When predicting the phenotype of the offspring from a dihybrid cross, why is it so important that each gene is located in a di

Bond [772]

Answer:

a) The genes present on separate chromosomes exhibit indepedent assortment.

b) The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

Explanation:

a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.

b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.

The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

Answer:

number 1 answer is 3.

number 2 energy is flowing upwards. ex grasshopper eats the grass, rat or whatever that is eats the grasshopper, and the hawk eats the rat. energy is going up each trophic level.

number 3. if the grass became polluted, then animals would get pollution in their bodies and at some point would die. eventually the grass would die too. primary consumers such as mouse, rabbit, grasshopper/snails would accumulate the most pollution because they directly eat the grass. whatever that is in the grass goes straight into their bodies.
