Answer:

Explanation:

Lets Tan seed be TT

Red seed be tt

A cross between TT ×tt will produce 4 Tt

TT× tt

!

F1 Tt Tt Tt Tt

a. Tan seed is dominant with an allele TT. It effect dominate that of red seed indicating it is a dominant traits while red seed is a recessive traits.

A dominant trait is a traits that is expressed in the phenotype of an organism the F1 generation are all Tan seeds this shows that the trait is dominant.

The genotype of the F1 melon is Tt in a dominant form

The F2 result follows the mendelian principle where segregation occur leading to a phenotypic ratio of 3:1

72Tan seeds:24red seeds

Where the 72 tan seed has the highest ratio and 24 red seeds has the smaller ratio.

Tt ×Tt

!

F2 TT Tt Tt tt

Phenotypic ratio 3:1

Which organisms synthesize carbohydrates, and in which cell organelle(s) does this synthesis occur?
ad-work [718]

Answer:

C

Explanation:

Green Plants are the main producers of starch as carbohydrate.In order to carry out this  special organelle Chloroplast are specially adapted  for this purpose,

Green plant are made up of Chlorophyll which are the green pigments that for trapping sunlight for the synthesis of starch to occur.

Photosynthesis is the process of synthesis of the starch.It involves the reaction of C02 with water  in the presence of sunlight  and enzymes to give oxygen as the byproduct, and Starch( carbohydrate) as the main product.

This process occur in two pathways the light dependent pathways and the light independent pathways,

Green plant and some organisms phytoplankons,algea are capable of producing starch  through photosynthesis because of the green pigment they possess.Therefore they are said to be Autothrophic.
