Answer:
i think it should be monerans e.g blue-green algae
Answer:
Guard cells prevents this from happening
Answer:
- fibrous joint between radius and ulna: C. syndesmosis
- fibrous joint that unites bones of the skull: H. suture
- articulation between teeth and bone: J. gomphosis
- joint with a cavity between bones: E. synovial
- the epiphyseal plate: F. synchondrosis
- articulation between two pubic bones: A. symphysis
- permits opposition and reposition: B. saddle
- fibrocartilagenous fluid filled sacs outside the joint cavity: G. meniscus
- most common degenerative joint disease: D. osteoarthritis
- movement of the sole laterally: I. eversion
Explanation:
The syndesmosis can be defined as a fibrous joint held together by ligaments. Sutures are fibrous joints of tissue that link the cranial bones of the skull. A gomphosis is a mobile fibrous that binds the teeth into sockets in the mandible and maxilla. Synovial joints are joints found between bones that move against each other (e.g., shoulder bones). They (synovial joints) are the most common class of joints found in the body. A symphysis is a cartilaginous, slightly movable, joint between two bones. A saddle is a synovial joint whose opposing surfaces are concave and convex, respectively. Osteoarthritis is the most common type of arthritis, this condition occurs when the protective cartilage surrounding the bones wears away over time. Finally, eversion refers to a type of movement of the foot which occurs in the auctioneering joint.
Answer:
Option (3).
Explanation:
Mark recapture method is used for the estimation of population size of an area. The individuals are identified by some mark on them. The formula of mark recapture method is
N = M * C/ R
Here, N is the number of the individuals, M is the individuals are marked and captured, C is the individual captured again with mark or non mark and R is recaptured marked individual.
The individual with 200 population, 20 are marked for the first time represent the large population size.
Thus, the correct answer is option (3).
Answer: Brain stem
Explanation:
The brainstem can be defined as a structure which is present in between the midbrain and the cerebrum. This controls the flow of information from the brain and the rest of the body. It also controls the functions like breathing, heart rate, consciousness, sleep and wake cycle and blood pressure. The brain stem consists of pons, midbrain and medulla oblongata.
