A nectar-eating bird has a slightly more curved beak than average for its species. This allows the bird to more easily access ne
ctar from plants. During the bird’s lifetime, it loses a toe on its left foot due to an accident. IT learns to compensate for this loss and is not greatly impacted. Which of this bird’s traits could it potentially spread through the species’ future population? Question 1 options: a. The slightly more curved beak because it is an acquired trait that would be beneficial to future offspring. b. The lack of a toe on the left foot because it is an acquired trait that would be beneficial to future offspring. c.The slightly more curved beak because it is a beneficial trait that is encoded in the bird’s genes. d. The lack of a toe on the left foot because it is a beneficial trait that is encoded into the bird’s genes.
Every change in a species is coded within the DNA. But the bird had lost a toe an accident. So the toe-loosing-option isn't true because not every bird looses his toe.
(Example: If a women gets bitten by a snake on the arm and gets the arm removed from her body and then in a year or so has a baby with her new husband. The baby won't be born with one arm because his/her mother lost her arm.) <span />
When homeostasis is not maintained, the body cannot function properly and illness may ensure. Homeostasis is the process in which the body's overall internal environment is kept constant in response to any external environmental changes. This involves maintaining stability in different body systems.
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles
The neuroendocrine system combines brain actions and and other bodily functions. In the brain, the hypothalamus maintains the balance (homoestasis) which affects other functions of the body such as metabolism, regulating reproduction, utilization of energy, drinking and eating behavior, blood pressure and osmolarity.
