1. How does the number of vascular bundles in the root compare to the number of vascular bundles in the stem? 4. In which region of the root would you expect to find the specialized cells of vascular tissue? 5. In which region of the root are the cells genetically identical? Explain why.

Answers

In terms of vascular plants, they help maintain the water cycle. The property of these plants enables them to carry out this function is their well-developed vascular system. These type of plants are more evolved and developed than nonvascular plants because of its specialized characteristics like xylem, which is a tissue that is responsible for its framework and not only that, it is also has a greater mechanism for water transference.

Which of the following is an example of a uniaxial joint? A. the saddle joint between the thumb and trapezium of the wrist
B. the hinge joint of the elbow
C. the joint between a metacarpal and the proximal phalanx
D. the ball-and-socket joint between the scapula and humerus
E. the plane joints between the carpal bones (wrist)

Answers

Answer:

B . The hinge joint of the elbow.

Explanation:

Uniaxial joint allows for motion in a single phase.

Final answer:

The uniaxial joint example from the given options is the joint of the elbow. A uniaxial joint allows for motion in one plane or axis only, like the joint of the elbow which allows primarily for flexion and extension.

Explanation:

The correct answer is option B: the joint of the elbow. A uniaxial joint is a type of synovial joint that allows for motion in one plane or axis only. Examples of uniaxial joints include joints, like the elbow or knee, and pivot joints, like the proximal radioulnar joint in the forearm. The elbow joint specifically is a joint because it allows movement primarily in one direction, that is, bending (flexion) or straightening (extension).

Clues to what ancient climates were like come from all of the following EXCEPT a. fossil trees. b. very old weather records. c. fossil tree rings. d. ancient plant pollen. make sure you know what u talking about too

Answers

The answer is b. very old weather records.

Fossils represent remains of organism from the past. Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue. Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.
Fossil tree rings, fossil trees, and fossil plant pollen are usually well preserved and can represent ancient climates. By knowing what kind of trees had lived in some past period and how they had pollinated can explain what climate were in that period.

Clues to what ancient climates were like come from all of the following (fossil trees, fossil tree rings, and ancient plant pollen) except b) very old weather records.
