Answer:
Nabuo at nagbago.
Paliwanag:
Ang bawat indibidwal ay dapat na binuo at ang mga pagbabago ay nangyayari sa kanyang hugis at istraktura sa pagdaan ng oras. Sa katawan ng organismo, ang mga cell ay patuloy na nahahati na responsable para sa pagtaas ng laki ng isang indibidwal. Sa ilang mga punto ang laki ng hihinto at ang mga bahagi ng reproductive parehong lalaki at babae indibidwal ay matured at gumana sa buong kakayahan at gumagawa ng isa pang organismo dahil sa pagsasanib ng kanilang mga sex cell.
They respire and give off c0^2
I would say estuary, because that's where a fresh water river and an ocean meet, and that leads to a transition between salt to fresh water.
Answer:
- 25 tall individuals, TT
- 50 medium individuals, Tt
- 25 short individuals, tt
Explanation:
<u>Available data</u>:
- The size of this species was determined by a single gene
- TT- Tall
- Tt- Medium
- tt- Short
- Total number of individuals in the progeny, N = 100
There are three phenotypes and only one gene, so it seems that this is an example of incomplete dominance, where the medium-size is the intermediate form between tall-size and short-size.
Cross: between two medium Gazorps
Parentals) Tt x Tt
Gametes) T t T t
Punnett square) T t
T TT Tt
t tT tt
F1) 1/4 = 25% TT, tall
2/4 = 1/2 = 50% Tt, medium
1/4 = 25% tt, short
100% of the progeny ------------ 100 individuals
25% Tall, TT ------------------------X = 25 individuals
50% Medium, Tt -------------------X = 50 individuals
25% Short, tt ------------------------X = 25 individuals
<span>In asexual organisms variation can occur from a variety of sources - mutations, homologous recombination and plasmid transfer. Mutations occur at a rate of roughly one base per million, meaning you would get between 0.1 and 10 in bacteria due to the size of their genomes.
In sexually reproducing organisms there are mutations and the crossing of gametes. The mutations occur in a near identical way to in asexual reproducing organisms as long as they occur in germline cells.
Asexually reproducing organisms reproduce much, much faster and so variation can occur more rapidly. For example the variation in the HIV viral propulation in an individual after 5 years is an immense diversity, higher than all the diversity that the human population has managed in thousands of years.</span>
