Knee joint - femur and tibia.

Hip joint - pelvis and femur.

Shoulder joint - scapula and humerus

Elbow joint - humerus, radius and ulna

Sacroiliac joint - sacrum and ilium.

<h3><u>Explanation:</u></h3>

The joints are defined as the connection between two adjacent bones which makes different structures. Joints are of different types - some are movable, while some are immobile.

The knee joint is a hinge joint which is a movable joint between the femur and tibia. This joint has synovial capsule, as well as synovial fluid to help in the movement. Knee joints are movable only in one axis.

Hip joint is also a mobile joint, between the femur and the acetabulum cavity of pelvis. This joint is a ball and socket joint, movable in all axis.

Shoulder joint is very similar to hip joint, being synovial joint. This joint is between the facet of scapula and humerus. This joint is the most movable joint of a human body, being able to rotate a complete of 360°.

Elbow joint is very similar to knee joint, which is also a movable joint between the humerus and radius- ulna. It's also a hinge joint, movable in one plane.

Sacroiliac joint is an immovable joint between the sacrum and ilium, which joins the pelvis with the vertebral column. This joint isn't a synovial joint.

Identify the role of DNA polymerase, Ligase, RNA Polymerase, DNA Helicase

likoan [24]

After another enzyme (a DNA helicase) has seperated two orginal strands of DNA, the polymerase moves along the template strand and polymerizes free nucleotides into a new antiparallel strand. ... DNA ligase joins pieces of DNA together, mainly joins Okazaki fragments with the main DNA piece.

Elephants are considered K-strategists because they give birth to only one calf at a time and most have five years in between ha

kicyunya [14]

Answer:

Type I curve

Explanation:

The K-strategist are species characterized by relatively stable populations that fluctuate at the carrying capacity of the habitat or niche in which organisms reside. Elephants are considered as K-strategists because they have a low population growth rate and relatively stable populations. There are three different types of survivorship curves. The Type I curve (also referred to as A curve) is characteristic of k-strategist organisms. Humans and elephants exhibit a Type I survivorship curve in which organisms tend to die when they become elderly. These species have a small number of offspring and provide parental care to ensure their survival. In a Type II survivorship curve, species produce many offspring and only some offspring survive (e.g., birds), while in Type III survivorship curve organisms produce many more offspring and most do not survive (i.e., r-strategists such as frogs or insects).

What is the major function of a leaf

ANEK [815]

Answer:

Photosynthesis

Explanation:

The leaf (from Latin fŏlĭum, fŏlĭi) is the vegetative and generally flattened organ of vascular plants, specialized mainly to perform photosynthesis. The morphology and anatomy of stems and leaves are closely related and, together, both organs constitute the stem of the plant.

Typical leaves - also called nomophiles - are not the only ones that develop during the life cycle of a plant. From the germination, different types of leaves follow each other - coiled, primordial leaves, prophilic, bracts and antophiles in flowers - with very different forms and functions.

A nomophile usually consists of a flattened sheet, a short stem - the petiole - that joins the sheet to the stem and, at its base, a pair of appendages - the stipules. The presence or absence of these elements and the extreme diversity of forms of each of them has generated a rich vocabulary to categorize the multiplicity of types of leaves presented by vascular plants, whose description is called foliar morphology.
