<span>The question asks us ""Which of the following does not accurately depict a scientific theory?" and first let's thing about theories- they are the best fit to the data, but can be changed if new data is found - they are not absolute facts, but out best explanation for the facts. They need to be constantly tested and in fact this is what scientists are doing as their job! So the correct answer is
D. Theories are absolute truths.</span>
Answer:
fills with blood during arousal and causes an erection.
Explanation:
The corpus spongiosum is a mass of tissue present in the under part of the penis (male sexual structure) that is actively responsible for erection of the penis. The corpus spongiosum, in conjunction with the corpus carvernosa works to maintain erection of the penis in males.
During sexual arousal, the corpus spongiosum, which surrounds the urethra (passage for urine and semen) helps keep the urethra open for semen to be released while the carvernosa becomes filled with blood. This constant flow of blood into the carvernosa makes the penis enlarge and assume an erect position.
When you are exposed to bright light, cells in the retina detect the stimulus and send it to the brain for processing. The brain commands the iris to constrict and decrease pupil size.
The structure that serves as a receptor in this system is Retina
<h3>How can we see the object?</h3>
Organisms adapted and evolved the eyes to see the surrounding environment. This ability to see begins when the visible wavelength of light enters the eye through a transparent covering called Cornea. The light enters the cornea and enters the inner of the eye through a round hole known as the pupil.
The light rays then enter the convex-shaped lens in the eye which focuses the beam of light on the back of the eye in the region of the tissue called the retina. The retina contains the photoreceptor cells-rods and cones in which the cone cells have the ability to detect three wavelengths of light especially blue, green and red which help us see various versions of the colour.
These cells convert light energy to chemical energy in the form of the action potential which gets transmitted to the part of the brain associated with the vision. This completes the pathway of the vision.
Thus, Retina is the answer.

Answer:
F1) 1/4 = 25% de la porgenie será AB, IAIB
1/4 = 25% de la progenie será heterocigota para el tipo A, IAi
1/4 = 25% de la progenie será heterocigota para el gruo B, IBi
1/4 = 25% de la progenie será homocigota recesiva, ii
Explanation:
- El gen I determina el tipo de sangre de una persona. Es un gen dialelico que muestra alelo dominante I y recesivo I.
- En personas de tipo A, los alelos son IA dominante, i recesivo.
- En personas de tipo B, los alelos son IB dominante, i recesivo
- IA e IB son codomiantes entre si, lo que signofica que hay un tercer fenotypo IAIB, expresando ambos tipos de sangre juntos.
- El alelo i es recesivo siempre.
Genotipo A:
- IAIA, Homocigota dominante
- IAi, Heterocigota
- ii homocigota recesivo
Genotipo B:
- IBIB, Homocigota dominante
- IBi, Heterocigota
- ii homocigota recesivo
Genotipo AB:
- IAIB, Homocigota dominante
