A Light Year is a mesurement of 5.879e+12 miles Compressed into one unit of mesurement or a "Light Year"

Light Years are used in the measurement of the universe because, to put it simply, SPACE IS BIG! The use of Light Years (5.879e+12 miles) Breaks the observable universe down into manageable chunks for astrologists.

What is the best way to get information concerning an athlete's psychological strengths and weaknesses
Marrrta [24]

Answer:

oral interview and psychological inventories

Explanation:

Through degree training, psychology professionals are acquiring a set of tools, techniques, procedures and methods, from different theoretical schools, which are used to evaluate and intervene with the people they work with. Some call these people "patients", but in the field of sport, it is preferable to speak of "athletes" or simply "individuals", since the word patient, from the biomedical paradigm, refers to "passivity", to someone who suffers pain and expects the professional to "take it away." The individual with whom the sports psychologist works (the athlete or the team, the coach, the referee or any other “actor” in the field of sport) could say, is a worker, that is, that is not waiting for solutions provided by the psychologist, but works helped by him to improve his psychological skills for training and competition, without neglecting his health and personal well-being.

    The objective of this work is to present the psychological interview as a tool widely used by professionals who work in this field, but little studied, in relation to its objectives, how to carry it out and its scope.

In pea plants, purple flowers are dominant to white flowers. Suppose two heterozygous purple-flowered plants (Tt) are crossed. W
iris [78.8K]

Answer:

75%

Explanation:

This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (T) is dominant over the allele for white flowers (t).

According to the question, two heterozygous purple-flowered plants (Tt) are crossed i.e. Tt × Tt. The following gametes will be produced by each parent; T and t. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

TT, Tt, Tt, and tt.  

Since purple allele (T) is dominant, offsprings TT, Tt, and Tt will be phenotypically purple-flowered. Hence, ¾ × 100 = 75% of offsprings will have purple flowers.
