valkas [14]

Explanation:

This is an example of relating structure to function.

Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns cells within the human body can generally be placed into four groups:

epithelial which refers to sheets of cells covering exterior surfaces and internal organs;
connective tissue which functions to bind cells and organs together while protecting, supporting and integrating different regions.
muscle tissue which responds to simulation, allowing for movement and locomotion;
nervous tissue which responds to electrical impulses, allowing for communication between different regions of the body

Connective tissue are usually spread out in a formation called a matrix. The matrix contains lots of extracellular components which are made by cells within connective tissue; it mainly consists of a fluid ground substance which interwoven with fibers of protein. Connective tissues mainly contain cells, the ground substance and protein fibers; each of these are present in varying amounts related to the structure and function of the tissue

It is further classified in to loose and dense tissue types which exists in multiple variations; in the loose tissue, fibers are aggregated loosely without a regular arrangement and often contains large spaces. Additionally connected tissue also contains cell types like fibroblasts. The loose tissue types, like adipose act as shock-absorbers and allow water, nutrients and salts to diffuse throughout the tissue to nearby tissue and cells.

Lipid droplets found in lipocytes, are organelles made up of a core of hydrophobic lipids. This is encased in a single layer of phospholipids which arrange themselves tightly and efficiently in a ball, with their hydrophilic heads facing outwards; while their hydrophobic tails face inwards. The phospholipid monolayer may also contain embedded proteins that at as special signals for recognition.

In lipocytes, one of these droplets may take up the intracellular space (white adipose) with the nucleus pushed to one side of the spherical cell- the cell takes the shape of the droplet, which allows storage maximization. They make up a type of loosely aggregated connective tissue, called adipose tissue,which function in cell signalling, as energy storage, and insulation.

State five qualities of good draught animals. State four precautions to be observed when using draught animals

lesya692 [45]

Answer:

1. Conformation

Conformation refers to the form or shape of an animal. An animal with good conformation has a shape which shows the normal characteristics of its species and breed.

An animal used for draft must have a build well suited for pulling. It should be low to the ground, have powerful shoulders and legs, and have a broad frontal dimension that will accommodate the placement of a harness. It must be big enough to deliver, alone or in a pair, the power needed to pull equipment for an extended period of time. It must also be able to exert the concentrated or "instantaneous" effort needed to overcome temporary increases in the draft requirement caused by roots, rocks, hard soil, or inclines.

While some animals are bred to produce good draft abilities, within any breed individual animals vary greatly in these qualities, and care must be taken to choose those with the most potential. A thin but well-balanced animal can be strengthened with a good diet, health care, and work. However, an animal with a swayback, bad legs or impaired vision will be a constant source of trouble.

Selection is a process of matching ideal qualities against those seen or latent in a given animal. Good draft animals, regardless of species or breed, will have the following qualities:

• head well proportioned; squarish, sculptured look

• balanced vision and hearing; head carriage high and straight

• normal mouth; good teeth and jaw structure

• body should have depth and width; short, full neck, full shoulders, broad chest, and straight, broad beck

• wide, thick hindquarters, lowset and evenly-fleshed

• short legs, straight and square to the body; ample bone

• clean, well-developed joints; no swelling or unusual boniness; no turning in or out of knees or hoofs; free movement of limbs

• feet straight, hard; normal angulation of hoof.

Temperament

Temperament refers to the nature or disposition of an animal. Part of its temperament is determined genetically, both by breed and parentage; some of it is learned-a response to the treatment it receives from other animals or the people who raise and handle it.

Temperament is reflected in an animal's behavior, the way it moves and acts, and the way it reacts to the things around it. It is difficult to know much about temperament from the quick evaluation that usually precedes the purchase of a draft animal. The buyer must guess, from what is observable, whether or not an animal will accept new routines or maintenance and training, behave well in a pair, and prove to be a spirited yet steady-paced and manageable worker. Sometimes, what is observable is not typical of the animal's behavior. A basically lethargic bull, for example, may become very alert or nervous at the approach of a stranger, exhibiting a fierceness that could be misinterpreted as a strong yet controllable spirit. A donkey that is mishandled and mismanaged might kick or butt at its owner, or at any adult, but be led away quite easily by a child. The buyer must be aware of such possibilities and at the same time drew some basic conclusions about the animal's temperament.

The following are signs of good temperament:

• Good overall conformation and health. The animal has no physical handicaps that require it to compensate with aggressive or stubborn behavior. An animal with bad vision or hearing, an unsound leg or joint, or with a chronic respiratory or muscular weakness, protects itself by balking, spooking, shying, refusing to be harnessed or lying down during work. Its temperament is affected or shaped by its physical condition.

• The animal accepts the handling of the owner. The owner can pick up the animal's foot, open its mouth, lead it with a rope without having to use force or harsh measures.

• It does not shy or kick at other animals. The buyer should try to be present when it is being turned out with a herd or put into a corral with other animals. If an animal is unusually aggressive or cowardly, it may not work well in a pair. Aggressive animals force their work-mates to shy or lean out of the yoke or harness, while cowardly animals may refuse to step evenly with their mates, lagging behind.

When an animal is taken from its herd or original owner and staked out or corralled in a new place, it may experience shock. The animal may show signs of aggression, withdrawal, stubbornness, fear, or general anxiety. None of these reactions is unnatural during the adjustment period, and should not be taken as a sign of an unsuitable disposition. An animal's character becomes clear later, during training and preseason work. At that time the farmer can judge the ability of the animal to work as part of a pair or team. Buying an animal early in the offseason allows the owner time to seek a replacement should a problem arise.

The relationship between the frog and the insects is a

gtnhenbr [62]

Answer:

The relationship between the frog and the insects is a predator-prey relationship. If the number of frogs in the ecosystem decreased because of human activity, there's a possibly that the number of insects might increase.

Explanation:

In this controlled ecosystem, frogs naturally prey on insects. If there were to be less frogs in the ecosystem, the number of insects might increase because there are fewer frogs to hunt them.
