After nuclear explosions animals and humans can continue to die due to ingestion of radioactive particles and nuclear ______________.

The distance from the sun to Neptune is about the same as the distance from Neptune to the next closest star, Proxima Centauri

Dragon Genetics and the Punnet Square.Dragon Genetics showing how the manipulation of alleles changed the dragon phenotype. Punnett square showing the traits of the fruitfly. Genetics is the study of biologicial  in heritance.

A Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.

The premotor cortex of the brain is responsible for this type of behavior.  Mirror neurons are activated during these times. The mirror neuron situated in the premotor cortex copies the behaviors or feelings observed, therefore, people watching exhibit the same behavior and feelings as the player itself when they lose a game.

The answers are as follows:
64. SKELETAL MUSCLES
Body location: it is usually attached to the bone or to the skin.
Microscopic anatomy: it is made up of very long, cylindrical multinucleated cells which are striated.
Regulation of contraction: the nervous system controls the voluntary contraction of the skeletal muscles.
Speed of contraction: the speed of contraction ranges from slow to fast.
Rhythmicity: the skeletal muscle is arrhythmic.
SMOOTH MUSCLES
Body location: found in the wall of hollow visceral organs [not including those of the heart].
Microscopic anatomy: made up of single fusiform, uninucleated cells that are without striation.
Regulation of contraction: smooth muscles undergo involuntary contractions which are controlled by the nervous system and hormones.
Speed of contraction: very slow. it is the slowest of the three muscles.
Rhythmicity: rhythmic.
CARDIAC MUSCLES
Body location: located in the wall of the heart.
Microscopic anatomy: it is composed of branching chains of cells, that are uninucleated; they are striated and posses intercalated discs.
Regulation of contraction: Undergo involuntary contractions, which are controlled by nervous system, heart pacemarker and hormones.
Speed of contraction: slow.
Rhythmicity: rhythmic.

65. Aging brings about gradual loss in muscle functions. As one grows older, there are usually age related alterations in the skeletal muscle functions. The factors that affect the rate of muscle loss are sex and level of muscle activity. Loss of muscle mass also occurs as one grows older.

66. The sliding filament theory states that, during contraction the thin filaments slide past the thick filaments and the sacomere shortens.
During contraction, the myosin head attaches to the myosin binding site on the actin filament. Using energy from ATP, the myosin head move toward the center of the sacomere, attaching and detaching several times. As a result of this, the thin actin filament is pulled toward the center of the sacomere. This leads to the shorten of the muscle cells.

The answers are as follows:
61. Deltoid muscle is the muscle that is located at the rounded contour of the shoulder. The muscle is made up of three different type of fibers, which are anterior, middle and posterior fibers. The anterior deltoid connects the collar bone to the humerus.
The primary function of the anterior fibers is flexion and medial rotation of the arm. The primary function of the middle fibers is abduction of arm and the primary function of the posterior fiber is the extension and lateral rotation of the arm. 

62. Adductor muscles are muscles that draw a part of the body towards its median line or towards the axis of an extremity. These muscles can be found in the thigh, foot and hand. The abductor muscles is made up of the following muscles:
a. Adductor brevis: its primary function is the adduction of thigh at the hip joint. It also assist in flexion and medial rotation of the femur at the hip joint.
b. Adductor longus: its primary function is the adduction of thigh at the hip joint. It assist also in flexion and medial rotation of the femur at the hip joint.
c. Adductor magnus: its primary function is the adduction of the thigh. It assists in lateral rotation of the thigh.
d. Gracillis muscle: its primary function is adduction of the thigh. It also assists in flexion of the knee and medial rotation of the flexed knee.
e. Pectineus muscle: Primary function is adduction of thigh. Assists in flexion of thigh.

63. Erector spinae muscles are bundles of paired muscles and tendons which extend through the thoracic, lumbar and the cervical region. These muscles are divided into three groups, which are:
a. Spinallis muscles: primary function is the extension of the head. Also rotate the head.
b. Longissimmus muscles: primary function is extension of the spine. Assist in lateral flexion of the spine.
c. Lliocostalis muscles: primary function is extension of the spine. Assist in lateral flexion of the spine.

64. Rectus abdomini is the paired muscle, which runs vertically on each side of the anterior wall of human abdomen. The muscle is made up of two parralle muscles which are separated by connective tissues. The primary function of the muscle is flexion of the vertebra column. Assists in compression of abdominal wall. 

Choice A, C, and D forms covalent bonds. Choice B is the only one hat has an ionic bond, making it the answer. I hope this helps.

The correct answer is B) One atom of calcium and two atoms of chlorine. I just had the same question on my 9th grade science test today. I hope I didn't give the answer to you too late and I hope it helps you out

 the orbital period is 5170 s

 During a charging by the friction process, the material that becomes negatively charged does so because it simply likes electrons more than the material with which it is rubbed.

Think about how friction functions when a car is trying to make a turn if the car is moving sufficiently slowly, then static friction between the car tire and the road cause's acceleration hope this helps 

I think it will be 100 kg
