Answer:
Ducks have no preference for white or wheat bread
Explanation:
The null hypothesis is the statement of no change (default). It proposes no relationship between the variables of the phenomenon under investigation. This hypothesis is usually considered to be true until proven otherwise by the experiment. It is designated as H0 and, if proven wrong, the alternative hypothesis (HA), is adopted.
That would be (d) most of the energy that drives metabolism supplied by ATP
Blood dries over time. How quickly this happens depends on the surface on which the blood landed, how much blood the spatter contains, and the heat and humidity at the crime scene, but as a rule the outer edges of the stain dry first. Consequently, after the interior portion flakes off or is smeared by an object, a dry blood spatter can skeletonize, that is, leave behind a ring similar in appearance (if not color) to a water ring on a coffee table. Patterns of drying help analysts determine how long an assault went on, detect whether it took place all at once or in stages, and nail down possible crime scene contamination. Clotting patterns in blood provide similar information and can help nail down the time factor if analysts arrive at the scene before blood can dry. Clotting begins within 3 to 15 minutes, but actual times vary by amount, surface type and environment. Mixed levels of clotting can indicate that multiple blows or gunshots occurred over time
Answer:
C) the facial nerve (VII)
Explanation:
The facial nerve (VII) is a cranial nerve. The cranial nerves are those nerves which arise from the brain. Most of the cranial nerves contain both motor and sensory neurons. Cranial nerves are connect to the various organs. Cranial nerves are associated with parasympathetic nervous system.
The facial nerve supplies nerve to many glands of the head and neck including lacrimal glands.
Thus, the facial nerve (VII) provided the stimulus to the lacrimal gland that cause tear while chopping oninons.
Answer:
Cells are membrane-bound groups of organelles that work together to allow it to function. Some of the major organelles include the nucleus, mitochondria, lysosomes, the endoplasmic reticulum, and the Golgi apparatus. Plant cells also include chloroplasts, which are responsible for photosynthesis.
