Low birth weight.
One of the most consistent and best documented effects of cigarette smoking during pregnancy is low birth weight.
Explanation;
Smoking during pregnancy has various effects on the fetus, causing a baby to be born early or to have low birth weight which makes it more likely for the baby to get sick and stay in the hospital longer.
Additionally; smoking during and after pregnancy is a risk factor of Sudden Infant Death Syndrome.
Diffraction occurs when a wave moves through an opening in a barrier. This causes the wave to change direction and spread out.
Waves can behave in three different ways depending on the obstacles they encounter. They can reflect, refract or diffract. In diffraction, waves such as sound, light or water either bend around small objects that obstruct their passage or spread out as they travel through a gap in the barrier.
The degree of diffraction forms a direct relationship with wavelength. It generally increases as wavelength increases. Conversely, the amount of bending lessens as wavelength decreases. However, if the opening of the barrier is smaller than the wavelength, the effect of diffraction is not easily observed. Hope this helps.
The answer is C because it’s something that can be caused by speciation, not can cause it
Answer:
Explanation:
A convex lens acts a lot like a concave mirror. Both converge parallel rays to a focal point, have positive focal lengths, and form images with similar characteristics. A concave lens acts a lot like a convex mirror.
