Answer:

Mutations

Explanation:

The term "mutation" describes a change that occurs in the DNA sequence of an organism. This change can be attributed to a great variety of reasons, such as mistakes when the DNA is copied, or due to environmental factors. This change contributes to the evolutionary process, and allows an organism to modify its structure and attributes.

You are studying a disorder that is based on the genetic composition at three loci. Assume that a dominant allele at any locus a
kramer

Answer:

28 units

Explanation:

This disorder follows quantitative inheritance. It is controlled by three genes which do not show the usual dominant-recessive relationship . The six alleles individually contribute to the effect which add up to produce the cumulative phenotype. Dominant allele contributes 6 units of risk whereas recessive allele contributes 2 units of risk.

Individual with genotype AABbCc has four dominant alleles (AABC) and two recessive alleles (bc). So their total risk units =

(6*4) + (2*2) = 24 + 4

= 28 units

DESCRIBE the internal anatomy of skeletal muscle, using each of the following terms: ACTIN, MYOSIN, THIN FILAMENT, THICK FILAMEN
jasenka [17]

INTERNAL ANATOMY OF SKELETAL MUSCLE : SKELETAL MUSCLE IS OTHERWISE CALLED AS STRIATED OR VOLUNTARY MUSCLE. THEIR ACTIVITIES ARE UNDER THE VOLUNTARY CONTROL OF NERVOUS SYSTEM. THEREFORE, THEY ARE KNOWN AS VOLUNTARY MUSCLES. PRIMARY FUNCTION OF THIS MUSCLE IS LOCOMOTION AND CHANGES IN BODY POSTURE.

EACH MUSCLE IS MADE UP OF NUMBER OF MUSCLE BUNDLES OR <u>FASCICLES</u>. THESE FASCICLES ARE HELD TOGETHER BY A COMMON COLLAGENOUS CONNECTIVE TISSUE LAYER CALLED FASCIA.

EACH MUSCLE IS COMPOSED OF NUMEROUS MUSCLE FIBRES AND IT IS MULTINUCLEATED, CROSS STRIATED CYLINDRICAL CELLS. IT IS MADE UP OF SARCOLEMMA OR CELL MEMBRANE ENCLOSING SARCOPLASM (CYTOPLASM) . NUMBER OF EVENLY DISTRIBUTED LONGITUDINAL THREADS CALLED <u>MYOFIBRILS</u> ARE PRESENT IN THE SARCOPLASM.

MUSCLE-FASCICULE-FIBRE-MYOFIBRILS-MYOFILAMENTS

EACH MUSCLE IS AN INDIVIDUAL CELL AND CONSISTS OF FOLLOWING PARTS.

SARCOLEMMA,  SARCOPLASM, NUCLEI,  MYOFIBRILS, MYOFILAMENTS, MITOCHONDRIA, SARCOPLASMIC RETICULUM.

SARCOLEMMA IS CELL MEMBRANE OF MUSCLE FIBRES AND SARCOPLASM IS SEMIFLUID CYTOPLASM OF MUSCLE.

NUCLEI ARE MULTIPLE IN NUMBER AND OVAL IN SHAPE, PERIPHERAL IN DISTRIBUTION BENEATH THE SARCOLEMMA.

<u>MYOFIBRILS</u> ARE CONTRACTILE UNBRANCHED THREADS SITUATED ALONG THE MUSCLE FIBRE.  IT CONSIST OF ALTERNATE A-BAND

AND I-BAND. EACH MYOFIBRILS CONSISTS OF LONGITUDINALLY ARRANGED PROTEIN FILAMENTS SUCH AS <u>THIN FILAMENT</u> CONSISTS OF <u>ACTIN,</u> TROPOMYOSIN, TROPONIN WHEREAS<u> THICK FILAMENT</u> CONSISTS OF<u> MYOSIN</u> . THESE ARE CALLED MYOFILAMENTS.

MITOCHONDRIA PROVIDES ENERGY FOR THE WORK OF  MUSCLE FIBRE.

BESIDES THE ABOVE COMPONENTS THERE ARE THREE TYPES OF SUPPORTING TISSUES WHICH HELPS IN ORGANIZATION OF SKELETAL MUSCLES. THESE ARE.

<u>ENDOMYSIUM</u> : IT IS A DELICATE SHEATH OF CONNECTIVE TISSUE WHICH COVERS EACH MUSCLE FIBRE OUTSIDE THE SARCOLEMMA.

<u>PERIMYSIUM</u> : THE MUSCLE FIBRES ARE GROUPED INTO FASCICULI EACH FASCICULUS IS COVERED BY A CONNECTIVE TISSUE SHEATH CALLED PERIMYSIUM.

<u>EPIMYSIUM</u> : THE ENTIRE MUSCLE IS COVERED BY A SHEATH OF CONNECTIVE TISSUE KNOWN AS THE EPIMYSIUM.

Explain went experiment​
Leya [2.2K]

When Went placed the agar block on one side of the decapitated shoot, the shoot curved away from the agar as it grew. This demonstrated that some kind of hormonal signal had diffused into the agar from the coleoptile tips. ... Went's experiment represented the first time that anyone had isolated a hormone from plants.
