<span>Nails are hard plates of tightly packed keratinized cells. They are clear and cover the dorsal surface of the last phalanges of fingers and toes. Nails protect the the ends of the fingers, allow us to scratch various parts of our body and help us grasping and manipulating small objects.
</span>The site of nail growth is the nail matrix<span> that is found beneath the nail root. The nail matrix is thick and is only composed of the deeper layer of the epidermis: the stratum basale (or germinativum). The keratinization of the cells of the nail matrix proceeds in the absence of a stratum granulosum and lucidum and this results into formation of a of a rigid and durable plate. As the nail matrix thus proliferates and differentiates, this hard plate is pushed forward onto the nail bed and the nail grows.</span>

How does the brain primarily interpet the strength of a stimulas in the nervous system
Valentin [98]

Answer:

The brain primarily interpret the strength of a stimulus in the nervous system based on the frequency of the action potential. This answer has been confirmed as correct and helpful.

the saclike shape of lipocytes allowing them to store more fat is an example of The following them in biology structure to the f
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.

Likurg_2 [28]
Interspecific competition
A type of competition in which organisms belong to different species compete with each others for same resources.
Example
Leopard and lion.
intraspecific competition
A type of competition in which organism belong to same species compete with each others for same resources.
Example
birds for breeding or shelter compete with each others
