Heat detection is needed for breeding.There is a system called timed breeding or the appointment breeding which is made so that the onset of heat and ovulation are induced for an animal to be inseminated at the right time. These then will help the breeder as well as the owner.
Answer:
Pansy 1 Genotype: TtRr
Pansy 2 Genotype: ttrr
Pansy 1 Gametes: TR, Tr, tR, tr
Pansy 2 Gametes: All tr
Phenotypic ratio of offspring: 1:1:1:1 (1 Tall red: 1 Tall white: 1 Short Red: 1 short white)
Explanation:
This is a cross involving two different genes; one coding for height and the other for colour in pansies. The allele for Tallness (T) is dominant over the allele for shortness (t) in the first gene while the allele for red color (R) is dominant over the allele for white color (r) in the second gene.
According to the question, a pansy
that is heterozygous for both traits will have a genotype: TtRr while a pansy that is homozygous recessive for both traits will have a genotype: ttrr
In a cross between a TtRr and ttrr, the following allelic combinations of gametes will be produced by each pansy;
TtRr- TR, Tr, tR and tr
ttrr- tr, tr, tr, tr
Using these gametes in a punnet square (see attached image), a phenotypic ratio 1:1:1:1 consisting of (4 Tall red: 4 Tall white: 4 Short Red: 4 short white) offsprings will be produced.
DISPOSAL is the act of safely removing or discarding of harmful chemicals form the lab.
Disposal is defined as the systematic destruction or orderly displacement or arrangement of garbage that will minimize its negative effects on its surroundings.
Thermal energy is transferred during heating.
What is thermal energy?
- Thermal energy refers to the ability to do work. As such thermal energy can also be defined as the ability of something to do work as a result of the movement of its particles.
- In other words, thermal energy is the energy possessed by an object or body by virtue of the movement of its constituent particles.
- It is the total internal kinetic energy of an object due to the random motion of its atoms and molecules.
- Thermal energy is a type of kinetic energy owing to the fact that it results from the movement of particles. Kinetic energy is the energy possessed by an object due to its motion.
- Thermal energy forms the foundation of the study of heat energy and thermodynamics. It is one of the oldest forms of energy utilized by mankind.
- Its usage existed even before petroleum and nuclear power sources were discovered.
