Explanation:
It includes features from all cell types. A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.
Answer:
Photosynthesis converts light energy to chemical energy in plants and cellular respiration converts biochemical energy from nutrients in organisms.
Explanation:
- Photosynthesis is a process that occurs in green plant that synthesizes food for plants from the use of sunlight and series of chemical reactions.
- Similarly cellular respiration also does the same but it uses nutrients consumed from the body to produce energy for different cellular activities.
- Cellular respiration converts energy into ATP form in organisms.
- Photosynthesis uses sunlight where as cellular respiration needs oxygen to prepare food and energy.
DNA testing utilized particular regions in our DNA that are unique to every individual. These regoins are tested using tehcnques such as RFLPs (Random Fragments Length polymorphisms), SNP (Single Nucleotide Polymorphism), STR (Short Tandem Repeats), Y chromosome (for males) and mitochondria DNA analysis (for females).
Answer:
scientific laws are descriptions of specific relationships under given conditions in the natural world
Cross of true breeding dominant and recessive tomato plants will have:
Phenotype ratio in F1 generation is 4:0
genotype ratio in F1 generation is 4:0.
Explanation:
Data given:
Tall vine = dominant TT
dwarf vine = recessive tt
red fruit dominant RR
yellow fruit recessive rr
true breeding tall tomato plant bearing red fruit is TTRR
true breeding dwarf tomato plant bearing yellow fruit = ttrr
the cross is shown in punnet square:
TR TR
tr TtRr TtRr
tr TtRr TtRr
the phenotype ratio- 4:0
the genotype ratio - 4:0
The phenotype is tall vine with red fruit
Genotype is all the progeny are heterozygous dominant.
