Answer:
cell walls, vacuoles, chloroplasts, centriole
Explanation:
Plant cells have cell walls, one large vacuole per cell, and chloroplasts, while animal cells will have a cell membrane only and several smaller vacuoles. Animal cells also have a centriole, which is not found in most plant cells.
Answer:
D)
Explanation:
Color is determined by a sex-linked gene, X gene, so, in order to that, the gene is maternally inherited. When one gene is related to the X chromosome, and one of the alleles is recesive and the other, logically dominant, the first generation will be of a single color, and the second generation will be of the other single color.
<h2>Answer:</h2>
The correct answer is option D which is bones provide structure and support to the body, while muscles move the bones.
<h3>
Explanation:</h3>
- The muscles are composed of muscle cells, 3 layers of connective tissues are also associated with muscles.
- Muscles are soft tissues of body which have ability to contract and relax.
- Bones are hard tissues composed of collagen fibers and inorganic minerals. Muscles are attached with bones. Due to hard structure, bones provides support and structure to body. While muscles are attached with bones, and their contraction and relaxation is the cause of movement
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.
