I think the answer your looking for is smooth muscles and cardiac muscles. They only muscles that can be voluntarily controlled is skeletal muscles. Let me know if this is what you're looking for:)
<u>Answer:</u>
You try to pick up a shell in the water but it isn't where it appears to be is an example of diffraction
<u>Explanation:</u>
Diffraction refers to the light bending that happens as the light passes about the edge of some object. How much bending takes place is found by the size of wavelength of light relative to that of opening. If the opening is larger than the wavelength of light, then bending will not be noticeable.
Since, light gets diffracted due to water hence the shell kept inside the water appears to be at a different position than where it actually is
Answer:
(c) directional selection
Explanation:
Directional selection is a type of natural selection that occurs when members of a population of a species with a particular extreme phenotype is selected or favored against the other phenotypes when natural forces act on the population of a species. Individuals having the particular traits that are favored survive and become more common that others with traits that are less favored.
Directional selection may likely result in the species of butterflies in which darkly collared butterflies are not preyed upon, ensuring their survival, while the other butterflies with other colors will be phased out with time. Darkly colored butterfly will be selected for while the others will be selected against.
The response that is most accurate is that; with age, your arteries lose their elasticity and are replaced with collagen, which makes your arteries stiffer. Systolic hypertension or pressure is an elevated systolic blood pressure. If the systolic blood pressure is elevated (above 140) with a normal (<90) diastolic blood pressure, it is called the isolated systolic hypertension.
Why do melting ice caps make Earth warmer?
The correct answer is C. Albedo decreases.
When the albedo is lower, more radiation from the Sun gets absorbed by the planet resulting in rise of temperature. When the snow covered area warms up and melts, the albedo goes down and more sunlight is absorbed in that area and the temperatures increase.
