Answer:
you agree with Al
Explanation:
Al's answer is most accurate because plants have chlorophyll, which they use to trap rays of sunlight to make their own food (photosynthesize) and Plants have mitochondria and can perform cellular respiration.
Answer:
d. 1/2
Explanation:
According to this question, PKU (Phenylketonuria) is a recessive condition in humans. A normal human must possess at least a dominant allele in the gene.
In a situation where two normal parents produce a child with PKU. This means that both parents are heterozygous for the condition i.e Pp × Pp. Hence, the heterozygous male (Pp) will produce gametes in the following proportion: P (1/2) and p (1/2).
This means that the probability that a sperm from the father will contain the PKU allele (p) is 1/2 or 50%
A. The sun, because there has been theory’s of the sun being able to heat earth from there being a lot of iron in the middle of earth.
Producers are organisms (usually plants) that utilize photosynthesis to produce their own food supply.
Photosynthesis is a process that uses photons from the sunlight to turn glucose and oxygen into carbon dioxide and energy. It basically is a process that uses light energy to make a usable food source, and it takes place in the cells of a chloroplast.
Chlorophyll is a green pigment found inside of plants' chloroplasts that absorbs light photons, allowing photosynthesis to take place.
Answer:
The sequence is b, a, d, c.
Explanation:
Pulmonary ventilation may be defined as be defined as the simple process of intake of oxygen and exhale of carbon dioxide known as breathing. Diaphragm contracts during inspiration and relax during exhalation.
The pulomonary ventilation occurs when the skeletal muscle contraction occur by the stimulation from the brainstem nuclei. This leads to the changes in the volume of the thoracic cavity. The thorax changes its shape by contraction and relaxation, this leads to the pressure change. Then air flows down the pressure gradient.
Thus, the correct sequence is b, a, d, c.
