What is the most commonly used method for discovering exoplanets?
Radial Velocity (AKA Doppler Shift)
What are the nerves that pass the elbow?
Radial Nerve, Ulanar Nerve, and Musculocutaneal Nerve. The ulnar nerve is more commonly known as the "funny bone".
How are snail eggs formed?
Spiral holoblastic cleavage is characteristic of several animal groups, including annelid worms, some flatworms, and most mollusc's. It differs from radial cleavage in numerous ways. First, the cleavage planes are not parallel or perpendicular to the animal-vegetal axis of the egg; rather, cleavage is at oblique angles, forming a "spiral" arrangement of daughter blastomeres. Second, the cells touch one another at more places than do those of radially cleaving embryos. In fact, they assume the most thermodynamically stable packing orientation, much like that of adjacent soap bubbles. Third, spirally cleaving embryos usually undergo fewer divisions before they begin gastrulation, making it possible to follow the fate of each cell of the blastula. When the fates of the individual blastomeres from annelid, flatworm, and mollusc embryos were compared, many of the same cells were seen in the same places, and their general fates were identical Blastulae produced by radial cleavage have no blastocoel and are called stereoblastulae._______________________________________________________________________P.S.

What nerve is particularly vulnerable to injury in a shoulder dislocation human anatomy?
All nerves forming the brachial plexus are vulerable to injuries. Most commonly affected are axillary nerve, suprascapular nerve and the radial nerve. The axillary nerve is injured in 37% making it the most commonly injured structure with this type of injury.Suprascapular nerve at 29%, and the radial nerve (22%).
Do diatoms have a radial or radial and bilateral symmetry?
Both!
What is radial cleavage?
Radial Cleavage is a type of Holoblastic Cleavage. You can get Isolecithal, Radial Cleavage which gives you equal yolk distribution between blastomeres. And you can get Mesolecithal, Radial Cleavage which gives moderate yolk distribution but it tends to have some asymmetrical distribution of the yolk which causes some blastomeres to be slightly smaller. (At least this is what it seems to be to me...) Previous Answer: i think it means giant boobs. don't really know sorry
Which phyla are classified in the deuterostomia?
The phyla classified in Deuterostomia are Echinodermata and Chordata. These phyla exhibit a unique pattern of embryonic development where the blastopore becomes the anus, and radial cleavage occurs during cell division.
Among coelomates in which of these does development occur by radial cleavage and the anus forms before the mouth?
Protostomes
Are all deuterostomes coelomates?
Coelomates are either deutermostomes or protostomes. A protostomes have spiral cleavage lie mollusks, annelids, and arthropods. A deutermostomes has radial cleavage such as echinoderms, and chordates.
What are the five key evolutionary changes in the animal body plan?
The evolution of symmetry, tissues, a body cavity, patterns of embryonic development, and segmentation (repeated body units). Symmetry is found as radial symmetry (halves of the body mirror each other) and bilateral symmetry (symmetric in every direction). Cells differentiate into tissues which allows for specialized structures and functions. The evolution of body cavities allowed for the evolution of organ systems. There are 2 patterns of embryonic development in bilateraly symmetrical animals: protostomes and deuterostomes. Other embryonic development classifications are cleavage patterns (spiral and radial), determinate or indeterminate development, and coelom formation. With segmented animals, each segment has a set of organ systems. This is advantageous because if one segment is damaged, the animal will not die. Segmentation also allows animals to move more effectively since the segments can move fairly independently.

Is jellyfish symmetry radial or bilateal?
A box jellyfish is considered to have radial symmetry. The box jellyfish belong to the animalia kingdom and the Cnidaria phylum. it is radial because it is formed from the central point Jellyfish often have tetramerous radial symmetry, which is symmetric across two axes. (Four symmetrical sections.)
What is the pulse in your arm called?
There's actually two pulses in your wrist. The most commonly used and easiest to find is your radial pulse. The radial pulse can be found by starting at your thumb and moving down to your wrist. Your ulnar pulse is harder to find and is found on the opposite side by tracing down your pinkie finger.
What nerve supplies the muscle on the radial side of the hand?
Of the muscles within the hand, the median nerve (C8, T1) commonly supplies two radial lumbricals, opponens pollicis, adductor pollicis brevis and flexor pollicis brevis. These all lie on the radial side. All other muscles of the hand are supplied by the ulnar nerve (C8,T1).

Radial Nerve, Ulanar Nerve, and Musculocutaneal Nerve. The ulnar nerve is more commonly known as the "funny bone".
Which artery runs in the radial groove with radial nerve?
radial artery
