Answer:
A. Heritable
C. Affected by the MC1R gene
D. Polygenic trait
Has evolved due to evolutionary processes such as natural selection.
Explanation:
Human skin color is a polygenic trait as it is regulated by more than one gene. Each allele of these genes has an additive effect on the overall skin color of an individual. Therefore, the trait is a continuous trait, not a discrete one. The genes for human skin color are transmitted from parents to progeny which in turn makes it a heritable trait.
The gene MC1R codes for melanocortin 1 receptor and thereby, regulate the skin color of humans since melanocyte-stimulating hormone binds to the receptor to trigger the synthesis of melanin from melanocytes. Evolution of various skin color in human beings is regulated by natural selection which in turn favors the skin tone best suited under the prevailing climatic conditions of a particular human population
Anterior Pituitary or adenohypophysis has two parts: pars distalis and pars intermedia..though they are kinda joined in humans.
•Pars distalis (actuallyknown as the anterior pituitary) secretes hormones like Growth Hormone or Somatotrophin, Prolactin, TSH, ACTH,LH,FSH.
•Pars intermedia secretes only one hormone MSH (Melanocyte Stimulating Hormone)
•Posterior pituitary or Neurohypophysis stores two hormones (originally secreted by the hypothalamus) which are Oxytocin and Vasopressin or ADH.
Cheers..dont forget to deem this answer as a brainy answer :)
Answer:
Research
Explanation:
Research is a deliberate attempt to find answer or solution to a problem along with help of observation, study, survey, comparison, literature review and experimentation.
It is in other way a search for knowledge through systematic way of finding solutions to a problem.
The research methodology comprises of following stages –
Stage I – Observing a problem
Stage II – Formulating a hypothesis
Stage III – Collecting the data
Stage IV – Analysis of facts and data
Stage V – Finding a solution or reaching a conclusion
Four abiotic factors in a prairie ecosystem would be soil, climate/temperature, water, and oxygen. Hope this helps!
