Answer:
involuntary; voluntary
Explanation:
Involuntary behaviors in organisms are unlearned behaviors exhibited as a reflex response to a stimuli around their environment. They are usually unconscious behaviors. On the other hand, voluntary behaviors are deliberate behaviors exhibited by an organism consciously. They are actually under the control of the organism, and can be learned.
If Inez blinks her eyes because a gnat flies close to them, that's involuntary. But if she then swats at the gnat, that's voluntary.
Lets say that the genotypes are:
Male affected:XbY
Male unaffected: XaY
Female affected: XbXb
Female carrier: XaXb
Female unaffected:XaXa
P: XbY x XaXa
F1: XaXb XaXb XaY XaY The middle square is female carrier.
P:XbY x XaXb
F1: XaXb XbXb XaY XbY The left square is affected female.
P:XaY x XbXb
F1: XaXb XaXb XbY XbY The right square is affected male.
The Earth was first considered habitable when we discovered that it was Microbial organisms that started the process. I would go with D.
Answer:
Option A, by having a constant supply of blood
Explanation:
Blood that flows to the muscles bring oxygen from the atmosphere to the contracting muscles where it gets consumed. During large muscle exercise, two physiological needs arise – a) high and prolonged muscle blood flow and b) regulation of blood pressure so that there is adequate perfusion of pressure to all organs. In order to meet both the requirements, the blood flow increases so that the vasoligating muscles do not outstrip the cardiac output.
Hence, option A is correct
Answer:
Venus flytrap communicate with other organisms by secreting a sugary substance (nectar) in its leaf glands.
Explanation:
The Venus flytrap is a carnivorous plant that traps insects in a plant structure that closes when the small hairs on the inside of the structure are touched.
The leaf of this plant contains a watery fluid secreted by glands on its open traps. Organisms like flies are attracted to the secreted nectar and perches on it; only for the hairs of the flytrap to get shut due to that touch and cell expansion triggered.
