An organism in which the two copies of the gene are identical that is, have the same allele is called homozygous for that gene
Answer:
Supraspinatus.
Explanation:
Supraspinatus is the small muscle that lies that lies on the upper back region of the body. This muscle runs to the superior portion of the scapula into the humerus through the greater tubercle.
The supraspinatus muscles are mainly involved in the arm aduction and pulling of the head of the humerus. The builders shoe arm flexion. The biceps brachii muscle is involved in the arm flexion. The least that involved in the arm flexion is supraspinatus muscle.
Thus, the answer is supraspinatus.
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.
Parthenogenesis is a form of asexual reproduction that results in a viable egg. A good example of this would be the Mexican Whiptail Lizard. The answer would be the last choice, an egg develops without being fertilized.
Answer and Explanation:
Cell: Molecules get grouped in alive cellular units that have auto replication capabilities. It is the smallest structural unit capable of functioning by itself. A cell is capable of communicating with other cells, their membranes delimitate them and protect them, constituting a selectively permeable barrier, receives signals from the exterior and responds in different ways to the different signals. There are different cells with different sizes, shapes, and forms.
Tissue: A tissue is the organization and association of the same type of cells. Each tissue performs different functions. These tissues can be epithelial, adipose, nervous, muscular, and etcetera.
Organ: An organ is composed of different tissues that work together in a more complex function. Tissues form structures such as the heart, lung, kidney, brain, and etcetera. Each organ has its function.
Organ systems: When different organs get associated and work together, they become a system. Working together in a stable way organs maintain homeostasis.
