Based on the Scatter Plots a. For female cubs only, it appears to be more evidence that the more time a lion cub spends playing, the sooner the Cub is likely to begin hunting.
Since the researcher's guess is that the more extended the cubs play, the quicker their first hunt will happen, the graph ought to show a negative slope demonstrating that the higher the value on the y-axis, the Lower the qualities for the x-axis or the higher value on the x-axis, lower value on the y-axis.
This trend can only be seen in the case of female cubs, where cubs who played between 3.5 and 4 hours per day began hunting at 13 months, whereas those who played more than 4 hours per day began hunting at 12 months.
Male cubs, on the other hand, exhibit a more random distribution, with some cubs playing less than 3.8 hours per day and beginning hunting before 11 months, while others played more than 4.7 hours per day and began hunting after 13 months.

RNA stands for Ribonucleic Acid. There are 4 major types of RNA based on their size and function. The first one is mRNA. mRNA or messenger RNA that is translated into a polypeptide. It is responsible to carry information from the nucleus to the cytoplasm. It forms a template for protein synthesis.
The next type of RNA is tRNA, also called as transfer RNA. It binds to anticodon on one end and amino acid to another. They help in making the protein in the correct form. Then, rRNA, also called as ribosomal RNA is also involved in the process of making protein. The facilitate the coding of the amino acid coded by the mRNA.

The physiological reaction induced by nervous and hormonal signals that readies the heart, muscles, and other organs and systems in ways that promote survival is called fight or flight response.
An experience that is thought to be stressful or scary triggers the fight or flight response, an involuntary physiological response. An acute stress reaction that primes the body for battle or flight is triggered by the impression of threat, which stimulates the sympathetic nervous system. A physiological response called the fight-or-flight response takes place in the presence of an alleged dangerous occurrence. In order for us to move, muscles pull on the joints.

when a trait is sex-linked recessive, how does that affect the likelihood of the phenotype being expressed in a hemizygous individual versus an individual who is homozygous or heterozygous
In case of sex-linked recessive trait, the hemizygous individual will always show the phenotype and the trait is more common in hemizygous individuals i.e. males. In case of heterozygous individuals which can be females they carry the allele as a carrier and do not express any phenotype. The homozygous recessive females will always display the phenotype.
Sex-linked recessive is the trait where the gene for any mutation or disease is present on the X-chromosomes. It can only be expressed when both the X-chromosome contain the defective allele. However males being hemizygous can express the phenotype.
Heterozygous is the condition where the trait is present in any one of the homologous chromosomes. Any trait during heterozygous state will be expressed in dominant condition but not in recessive condition.
