Answer:
The plus end for all actin filaments.(Ans. A)
Explanation:
All three types of muscles (cardiac, smooth, and skeletal) utilize actin filaments to generate force which leads to cell contraction. Actin filaments is organized into sarcomeres which function as the fundamental unit of contraction.
Sarcomeres are approx 2.4 micro meter in length, and they are bounded at both end with the help of Z-disks. Plus end of the Z-disks are oriented with actin filaments and their minus ends to the direction of center of the sarcomeres. Z-disk consist an actin capping protein, which is known as cap-Z. Cap-Z helps to bind plus end of the actin filaments.
Answer:
Al children would have a Tall head shape
Explanation:
Patrick is purebred for the dominant tall head shape so his genotype would be TT. Patti on the other hand is short headed, which is recessive, so the only possible genotype would be tt. If we put that in a Punnet, you can see the result:
TT x tt
T T
t Tt Tt
t Tt Tt
Since all the results are Tt, that means the tall head shape would be expressed because it is dominant and it will mask the recessive trait. So the answer would be:
All children would have a tall head shape.
The correct option is, B, that is, RADIAL SYMMETRY.
Symmetry refers to the balanced distribution of the duplicated body parts or shapes within the body of a living organism. There are different types of symmetry, we have bilateral, radial and asymmetrical symmetry.
Radial symmetry refers to the type of body plan in which the body parts are arranged around a central axis, that is, the body parts are arranged in a circle around an axis.<span />
Environmental science is a branch of biology focused on the study of the relationships of the natural world and the relationships between organisms and their environments. An example of environmental science is the study of the natural world and how it relates to recycling and mulching.
