Answer:
C- Impair the ability to consider the consequences of acting impulsively
Explanation:
Alcohol consumption leads to an increase in the level of dopamine released in the brain, thus increasing pleasure. This increase in levels of dopamine can lead to impairment in reasoning and minor memory loss. With these factors, impulsive actions are more likely to occur. Aggressive behavior might eventually settle in, when euphoria eventually becomes depression.
Answer:
B. Both move across the sky from east to west.
C. Both change positions in the sky due to Earth's revolution.
E. Both appear in different positions in the sky due to Earth's rotation.
Explanation:
Sun and stars doesn't move in the sky. We see sun and stars move from east to west, it is due to the rotation of earth, not the movement of sun and stars.
Sun and stars are luminous objects, so only sun is visible at daytime and starts are not because sun is more luminous than stars.
<h3>Producers</h3>
Explanation:
Producers are autotrophic organisms capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis ( using light energy) or through chemosythesis (using chemical energy).
Examples are green plants, small scrubs, phytoplankton, algae
Answer:
- light positioning: c. Extrinsic muscles; d. Pupil
- sensory processing: a. Photoreceptors; b. Occipital cortex; e. Bipolar cells
Explanation:
Extrinsic (extraocular) muscles are muscles that modulate both eye movement and position, whereas intrinsic (intraocular) muscles are muscles that focus the eye and control how much light enters into the eye. The pupil is the black center of the eye within the iris through which light passes before being focused onto the retina. Photoreceptors are specialized neurons located in the retina that respond to light, converting it into electrical signals that can stimulate biological processes. Photoreceptors in the retina are divided into two categories 1-rods (responsible for vision at low light levels), and 2-cones (active at higher light). Bipolar cells are neurons that transmit signals from the photoreceptors to the ganglion cells, thereby processing light signals received from rods and cones. The occipital cortex is a brain region that represents the visual processing center and contains most of the anatomical region of the visual cortex.
Answer:
B. The smaller DNA pieces travel farthest towards the positive end of the box
Explanation:
Gel-electrophoresis technique is a technique which is used to separate the fragments of DNA based on their size. The technique is employed in the DNA fingerprint analysis.
The DNA samples are loaded on one side of the gel and when an electric current is applied, the DNA moves from the wells towards the electrodes.
The DNA is a negatively charged molecule which travels through pores in the gel and reaches towards the electrode with positive charge.
The smaller the size of the DNA fragment, the faster it moves.
Thus, Option-B is correct.
