Red squirrels and gray squirrels have been the native species on an island for many years. A few years ago, black squirrels ente

red this island. The black squirrel is an invasive species. Invasive species aren’t native to the ecosystem. They move into an ecosystem because of natural changes or human intervention. Red squirrels and black squirrels have identical food requirements, but gray squirrels have a different diet. What THREE effects will these events have on the island’s squirrel population?
-The food availability of red squirrels may increase.
-The red and black squirrels will have to compete for nutrition.
-The food availability for gray squirrels will not be affected.
-The food availability for red squirrels may decrease.
-The food availability for gray squirrels will be affected.

The THREE effects on the island's squirrel will be The red and black squirrels will have to compete for nutrition:

  • The red and black squirrels will have to compete for nutrition: As the invasive specie will also require food for its survival so there will be competition for nutrition.
  • The food availability for red squirrels may decrease: As red and black squirrels have identical food requirements so because of competition there will be less availability of food for red squirrels
  • The food availability for gray squirrels will not be affected: The gray squirrel have different diet, there is no competition of food for them

I would say the food availability for gray squirrels will be affected because we do not know their diet. It also say that the red squirrels and the black squirrels have the same diets meaning less food on the Island for the grey squirrel( depending on what he eats. )

The muscular system is made up of Multiple choice question. all the muscles plus the nerves attached to them. all the muscles, l
umka2103 [35]

Answer:

all the muscles.

Explanation:

The muscular system is composed of all muscles in the body. The main function of the muscles is to produce movement in different parts, voluntary or involuntary, creating equilibrium. Muscles are made of myocytes. There are three types of muscles: smooth muscle,  skeletal muscle, and myocardium.

  • The smooth muscle is formed by fusiform cells, mononucleated, and no transversal striations. There is a protein contraction system, but not as organized as the one of the skeletal muscle.  

Smooth-muscle can be found in organs, vessels, veins, and arteries. It provides sustained contractions, slow and rhythmical, but not voluntary.  

  • Skeletal muscle is the most abundant muscle in vertebrates, constituting the somatic musculature. It proportionates motion to extremities and digits and is responsible for the position and posture of the individual. It is also involved in eye movements, respiration, mastication, deglutition, and phonation. It moves the tongue, the superior esophagus, and the pharynx.  

The skeletal muscle is innervated by axons of the motor neurons coming from the CNS. The contraction of the skeletal muscle is voluntary and fast.  

Cells composing the striated muscle are significantly long and multinucleated. They arrange in bundles, where cells are parallel to each other.  

  • Myocardium tissue is more similar to the striated tissue than to the smooth one. However, there are some differences between them. Cardiac cells are cylindrical and smaller, with ramifications. Cardiac cells only have one nucleus, and occasionally there can be two. Actin and myosin filaments are arranged just as the skeletal ones, and the contraction of cardiac cells is molecularly very similar to the skeletal

Why algae in the ocean can have a very high NPP and a very low amount of stored biomass
USPshnik [31]
The algae in the ocean have a very high Net Primary Productivity (NPP) and a very low amount of store biomass. This is because THE GROWTH RATE OF ALGAE IN THE OCEAN IS HIGH. The store biomass is low because THE PRIMARY CONSUMERS FEED ON THESE ALGAE THUS LOWERING THE BIOMASS AMOUNT. The production of biomass is related to the NPP.
