Answer:
The correct answer is - 25%
Explanation:
A cross between true tall pea plant and heterozygous tall pea plant is the cross of tall allele whic is TT and heterozygous which is Tt, so the gametes will be formed would be - T and T by true tall plant and T, and t allele by heterozygous plant.
The Punnett square of this cross is attached with the answer, where 2 heterozygous offspring and two tall offspring produced. In which there is only two recessive short allele formed in this generation out of 8 alleles.
So the probability of short allele would be:
= (2/8) *100
= (1/4) *100
= 25%
Answer:
B. The model will include all planets of the solar system.
Explanation:
Plants provide us with oxygen, food, fuel and fiber. Among other reasons, scientists study plants to improve and secure the food supply for an increasing world population, identify new sources of bioactive compounds and medicines, improve fiber production and identify sources of biofuels and biorenewable resources.
Answer:
This is known as Population.
Explanation:
A population is made up of organisms of the same kind living together in the same habitat. Characteristics of a population include the population size, frequency, density, percentage cover and distribution.
Factors that dominantly affect a population comes up especially in size and distribution. These factors include; migration of organisms to other habitats, invasion or colonization by new species, increase or decrease in birth and death rates etc
Burning is a chemical process by which two atoms or molecules will combine with each other. In burning, the two atoms or molecules will combine and release energy. ... When the molecules combine and release energy, it is released in the form of heat and often light.
In the case of burning wood, stored potential energy (in the form of chemical energy) in the log is released due to heating by other excited atoms. This chemical reaction is called combustion and requires oxygen. Combustion changes the potential chemical energy into kinetic energy in the form of heat.
Energy is used to break bonds in reactants, and energy is released when new bonds form in products. ... The law of conservation of energy states that matter cannot be created or destroyed. Whether a chemical reaction absorbs or releases energy, there is no overall change in the amount of energy during the reaction.
