The correct answer is; <span>You conduct a dihybrid cross. a 12:1:1:4 ratio would make you suspect that the genes are linked. This is the expected phenotypic ratio for the dihybrid cross that would cause the genetic linkage i.e. formation of DNA sequences during the process of sexual reproduction. </span>
It's called a nutrient.
Nutrients are well, something that all humans need to survive. A certain amount of nutrients keep humans alive and healthy, yet a lack of nutrients will cause them to become sick and slowly die.
Thus, making it so nutrients is a chemical substance that organisms require to live.
Hope this helps!
1) - The coracobrachialis and pectoralis major muscles connect the humerus anteriorly to the scapula and ribs, flexing and adducting the arm toward the front of the body when you reach forward to grab an object.
- On the posterior side of the arm the teres major and latissimus dorsi extend and adduct the arm towards the scapula and vertebra when you pull an object down off of a shelf above your head.
- The deltoid and supraspinatus muscles run superiorly between the scapula and humerus to abduct as well as flex and extend the arm.
These muscles allow us to raise our arm in the air or swing the arm as in throwing a ball underhand.
2) cariac muscle makes up the heart, its involuntary, striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.
3) Smooth muscles are composed of elongated, spindle shaped cells and are commonly involved in involuntary motions. Skeletal muscles allow movement by being attached to bones in the body. Skeletal muscles control voluntary movements which can be consciously controlled.
4) Calcium is a crucial part of muscle contraction. The ionic element is released from muscles during contraction and relaxation. The release of calcium helps propagate the muscle contraction and relaxation stages. An adenosine triphosphate molecule stores energy that is released and used by energy-consuming reactions, such as muscle contraction, transmission of nerve impulses and formation of other molecules. ATP is found in cells and is made from the breakdown of food. It is composed of oxygen, hydrogen, phosphorus and carbon atoms. The energy in an ATP molecule is locked within phosphate bonds, which hold its phosphate groups together.
5) The muscle would neither contract nor relax if ATP was'nt there. It would stay in the same state because ATP is required for contraction as well relaxation of muscle. That is why dead bodies become very stiff.
Answer:
When food is plentiful, many Hydra reproduce asexually by budding. The buds form from the body wall, grow into miniature adults and break away when mature. so (A) budding is correct i believes
