During a routine physical examination on an older female client, a nurse notes that the client is 5 feet, 3/8 inches (1.6 m) tal

l. The client states, "How is that possible? I was always 5 feet and 1/2? (1.7 m) tall." Which statement is the best response by the nurse?
a) "The posture begins to stoop after middle age."b) "After menopause, the body's bone density declines, resulting in a gradual loss of height."c) "After age 40, height may show a gradual decrease as a result of spinal compression"d) "There may be some slight discrepancy between the measuring tools used."

In order for fsh to directly affect sertoli cell function, what is the first thing that happens when an fsh molecule is near a s
TiliK225 [7]

A Sertoli cell (a kind of sustentacular cell) is a "nurse" cell of the testicles that is part of a seminiferous tubule and helps in the process of spermatogenesis; that is, the production of sperm.

It is activated by follicle-stimulating hormone (FSH) secreted by the adenohypophysis, and has FSH receptor on its membranes. It is specifically located in the convoluted seminiferous tubules (since this is the only place in the testes where the spermatozoa are produced). Development of Sertoli cells is directed by the testis-determining factor protein.

These vertebrae attach to your hip bones. Select one: a. lumbar b. sacral c. thoracic d. coccygeal e. cervical
N76 [4]

Answer:

The answer is option b. sacral bones.

Explanation:

The sacral bones are a shaped like a triangle and found below the fifth (5th) lumbar vertebrae and in between the hip bones. The joint formed with the hip bones is called the sacroiliac joint.

A muscle fiber will respond to a stimulus when that stimulus reaches the __________ level. recruitment resting rigor mortis thre
saveliy_v [14]

When an external stimulus crosses the threshold, a muscle fibre will respond.

<h3>The level of the threshold</h3>
  • For the identification of the electrical activity carried out by the active muscles, the threshold level is a crucial consideration.
  • A portion of the electrical activity carried out by the target muscles may be excluded if the chosen threshold level is higher than the overall activity.
<h3>What is the stimulus threshold for muscle contraction?</h3>
  • A certain stimulus magnitude is necessary for muscle contraction.
  • The threshold stimulus is the smallest amount of force needed for a stimulus to cause a muscle to contract in response.
  • If the stimulus intensity is less than this threshold value, there is no response.

4. What is meant by the fact that water is a "polar" molecule?
Ksju [112]

Hello!

A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.

Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.

Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.

Hope this helps!

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.
