Why is the ulna less movable than the radius?

Biology
1 answer:

Ulna is less moveable than radius because it has a hinge joint with the humerus in the process of olecranon. This joint only enable you to extend or flex the lower hand but not rotation. This cause it becomes more stable and less prone to subluxation. Radius joint with the metacarpophalangeal bones in the hand is also a loose one that allows rotation movement.

Will give brainliest plz help <br> Answer 12 plz
Ivan

Answer:

Abiotic factors, such as temperature, water, sunlight amounts, and regional terrain, directly effect biotic factors. Biotic factors are the living components of an ecosystem which include primary producers, consumers, and dexomposers.

Abiotic factors can effect organisms in many ways. Hey can effect primary producers negatively if there is too little sun, water, or nutrients in the soil. However, if there is too much of any one of these, they can still be negatively effected. With primary producers, it’s all about balance.

while consumers do not directly require the above conditions, they do rely on the plants and animals that feed on said plants to survive. If the plants do not have correct nutrients, they will not either. As far as terrain goes, they adapt to better cope with the environment. If they live in an aquatic enviromment for example, they acquire ways to more efficiently move through the water to look for food.

Decomposers rely on the remains of dead plants and animals in order to survive. They feed off of dead matter and the waste gets deposited into the soil. This in turn helps to give the soil its nutrients, and so the cycle continues.

Everything in nature is reliant on each other. This delicate balancing act is both beautiful and so very fragile. If one organism is removed, the entire ecosystem could suffer. This is why it is so critical to protect the environment we share with every other living creature on this earth.

cual es la diferencia netre los cloroplastos y la cianobacteria si ambos son bacterias fotosinteticas???
Anna35 [415]

Answer:

Encontré esto en un texto de microbiología, tal vez sea útil.

Explanation:

"Las cianobacterias y los cloroplastos de las plantas tienen ambos fotosistemas, mientras que las bacterias fotosintéticas anoxigénicas sólo utilizan uno de los fotosistemas. Ambos fotosistemas son excitados simultáneamente por la energía luminosa. Si la célula requiere tanto ATP como NADPH para la biosíntesis, entonces llevará a cabo una fotofosforilación no cíclica".

Si estoy equivocado, pido disculpas. También lo he sacado de un traductor así que si suena mal también me disculpo por ello.
