Answer:

Bone

The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system.

Ligament

Ligaments connect the ends of bones together in order to form a joint. They also assist in holding organs in place. Tendon: A tough, flexible and inelastic band of fibrous connective tissue that connects muscles to bones.

Tendon

A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.

Cartilage

Cartilage: This smooth and flexible substance covers the tips of your bones where they meet. It enables bones to move without friction (rubbing against each other). When cartilage wears away, as in arthritis, it can be painful and cause movement problems.

Which shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the

iogann1982 [59]

Answer:

The correct answer is option d) "head-on".

Explanation:

In hunting, the head-on angle refers to a position at which the hunter and the prey are face to face. This shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the hunter as the animal is in front of the hunter. At the head-on angle it is harder for the hunter to kill an animal with the first shot and ruins a lot of meat because the animal produces hormones such as adrenaline result of the stress.

Different ratios occur in crosses with single gene pairs or two gene pairs. What types of ratios are likely to occur in crosses

likoan [24]

Answer:

Genotype ratio: 1, 1:1, 1:2:1

Phenotype ratio: 1, 3:1

Explanation:

Single gene pair cross is also known as monohybrid cross. This means that only one gene usually with two alleles is observed and it express one trait.

For example, if we name the gene for a certain trait with A, the possible genotypes are AA (dominant homozygous), aa (recessive homozygous) and Aa (heterozygous). Possible crosses are:

P: AA x AA

F1 : all of them are AA

The same is with aa x aa (all of the offspring are with aa genotype)

P: AA x Aa

F1: AA Aa AA Aa (genotype ratio 1:1) (phenotype ratio 3:1)

The same genotype ratio is in aa x Aa (offspring will have aa Aa aa Aa-(genotype ratio 1:1) (phenotype ratio 1:1)

P: Aa x Aa

F1: AA Aa Aa aa (genotype ratio 1:2:1) (phenotype ratio 3:1)

P: AA x aa

F1: Aa Aa Aa Aa (1)
