Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.
The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.
With an individual of F1 crosses with another individual of F1, the Punnet Square will be:
FfRrTt x FfRrTt
1) Dividing each characteristics, for simplicity:
F f
F FF Ff
f Ff ff
R r
R RR Rr
r Rr rr
T t
T TT Tt
t Tt tt
Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.
A conversational plan with two habitat preserves, measuring a total of 20 square kilometers combined will preserve more species because this cause segregation of species based on their adaptability towards a safer and secure environment. For example if a lion and deer try to live in the same conservation area, then it’s obvious that the life of deer is always at risk. But in cases of segregated preserved areas both herbivorous and carnivorous animals can live separately. Also if there is special inclination of one species towards other then also these two species can live separately.
Segregation also enhances the diversity in the sense that it could lead to a new ecosystem with a new ecological balance within it. Conservation biologists focus on these areas as they claim that where the greatest number of unique species can be found and protected with in the large number of reserve areas with the least amount of effort
Answer:
A) Formulate question,conduct research,propose hypothesis,test hypothesis
Explanation:
The scientific method is pertinent to the success of a scientific experiment. The scientific method is a sequential steps of processes involved in an experimentation. The correct order of steps that determines the process when following the scientific method are:
1) Formulate question: Asking a question about what has been previously observed is the key to starting a scientific method.
2) Conduct research: Research is done based on a previous observation that has been made by in order to gather necessary information.
3) Propose hypothesis: A hypothesis is a predictive statement or explanation to an asked question about the experiment that can be tested. It usually goes in an IF, THEN format.
4) Test hypothesis: As stated in the previous step, a hypothesis must be testable, which is done by conducting an experiment. The outcome of the experiment proves or disproves the hypothesis.
Answer:
Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.
