Most of the joints in the appendicular skeleton are __________ joints.
Semmy [17]

Most of the joints in the appendicular skeleton are synovial joints.

So, the correct option is (c).

  • A joint, sometimes referred to as an articulation, is where two or more bones come together. The names of two bones are included in each articulation.
  •  Immobile joints are ones that do not permit movement at the joint sites .These joints don't have a joint cavity; instead, dense fibrous connective tissue, typically collagen, holds the bones physically together.
  • A synovial membrane-lined joint capsule that produces synovial fluid surrounds and protects the two of them.
  • Specialized joints known as cartilaginous joints can be identified by their structural characteristics.
  • In fibrous joints, white connective tissue  fibres that travel from one articulating portion to the next separate the articulating parts.

Oliga [24]

Answer:

A. They were part of the control group

Explanation:

In a scientific experiment, the CONTROL GROUP as opposed to the experimental group is the group that does not receive the experimental treatment. This acts as a standard for comparison.

In this question, the EXPERIMENTAL VACCINE is the experimental treatment or independent variable that was added. The five animal test subjects that was injected with this vaccine are called the EXPERIMENTAL GROUP while the other five test subjects that were rather injected with a PLACEBO are called CONTROL GROUPS.

If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?
Afina-wow [57]

The complete question is:

If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?

  • Producers
  • Carnivore
  • Herbivores
  • Top predators

Answer: Top predators

Explanation:

The top predators get the least energy because according to the 10 per cent law the energy transfer only 10 energy is transferred to the next successive level.

The next level of the organism receives only 10 of the total energy that the previous level has.

Hence, the top predators have the least amount of energy in it as the energy is transferred through various levels before reaching top predators.

In humans, blue eyes are caused by a recessive allele ("b") that dilutes pigment production. BB and Bb individuals have brown ey
saveliy_v [14]

Answer:

Probability that the son will be:

color-blind = 1/2

blue eyed = 1/8

blue eyed and color-blind = 1/16

Explanation:

Mother : BbXcX

Father : BbXY

Colorblindness is X linked recessive trait hence will be caused when the son has XcY genotype.

XcX   X    XY :

     Xc    X

X  XcX  XX

Y   XcY  XY

Half of the sons will have normal vision and other half will be colorblind hence, there is 1/2 probability that the son will be colorblind.

Eye color is autosomal trait and blue color will be produced when the child has bb genotype.

Bb     X    Bb  :

   B    b

B  BB  Bb

b  Bb   bb

1/4 of the children will have blue eyes. Since half of the children are expected to be males, 1/4 * 1/2 = 1/8 sons are expected to have blue eyes.

Probability of a son being blue eyed and color blind will be :

1/8 * 1/2 = 1/16
