I REALLY NEED HELP. I DO NOT GET THIS AT ALL. PLEASE HELP ME. IT WILL BE GREATLY APPRECIATED.
kati45 [8]

Answer:

The test cross is shown below

      T         T

t      Tt         Tt

t       Tt         Tt

The alleles shown in the vertical side (tt) are recessive and come from the male parent. The alleles TT are dominant and come from the female parent.

For the variety of offsprings to be 100% tall, the recessive parent had to be crossed with a homozygous dominant parent.  If the female was heterozygous with which the cross was done,then there would be small tomato plants in the offspring generation.

1. A normal mammalian cell will shrink if it is placed into_________. (Assume all solutes are non-penetrating) A. pure water B.
GrogVix [38]

Answer:

B. 50 mM glucose; E. 300 mM glucose

Explanation:

In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.

The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.

The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.

Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as monohybr
Mademuasel [1]
Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as true-breeding. In this process the parents will pass down specific phenotypic trait of their offspring.  True bred organisms will have pure genotype (genetic make up of an organism) and will therefore produce certain phenotype.
