Answer: C: rock climbing E: free diving  

F: hiking

Explanation:

Rock climbing is a sports activity in which the participants climb up the mountain or hill, or a rocky wall of a appreciable height. The goal of this sport is to reach the highest point or the endpoint in shortest time.

Free diving is the sport, in which the person dives inside the water by holding breath for long until the person reaches over the surface layer of the water body. This practice is different from scuba diving as no breathing apparatus is used in free diving.

Hiking is a sport in which the individuals walk for long to cover a long distance, without using any vehicle in the journey.

The above mentioned sports can only be performed by the participants who are healthy and fit. Their respiratory and cardiovascular system should be free from any disease or disorder so that they can complete their tasks in the sports without becoming weak. Their muscular and skeletal system should also be sound which can facilitate easy and flexible movements during the beginning of the sport.

Lynna [10]

Answer:

Malignant melanoma cells would have active telomerases that constantly replenish and lengthen telomeres.

Explanation:

Telomerase can be described as enzymes which add the repetitive sequences called telomeres at the end of a chromosome. Telomeres can be described as repetitive sequences at the end of the chromosome which are involved in protecting the chromosome from any damage.

In a normal skin cell, the telomeres will shorten with time. But in a malignant skin cell, the telomerase will add the repetitive sequence again and again. The telomers will not be able to shorten.

In a phospholipid bilayer, the __________.a. phosphate groups are hydrophobic. b. fatty acid tails are ionized. c. fatty acid ta
den301095 [7]

Answer:

Option-E

Explanation:

The phospholipid bilayer is the layer which forms the outer membrane of the cell.

The phospholipid layer is amphipathic as it contains both the hydrophilic and hydrophobic portions.

The phospholipid is composed of the glycerol attached to phosphate groups which form head or hydrophilic region and the 3 fatty acid tails which form the hydrophobic portion.

The head or hydrophilic portion is arranged in the layer facing the outer external portions and the inside of the cytoplasm as the lipid layer exist in the bilayer.

Thus, Option-E is correct.

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.
