If the food type changes in a given environment, then the amount of each type of bird beak will change as birds with beaks more suited to the available food will consume more successfully over time. The independent variable of the lab is the type of food that is available to the birds. The dependent variable of the lab is the frequency of each type-size and shape-of beaks. The conclusion will state that favourable traits place one species in a more optimal position to survive in a given envronment.

If the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

As the popliteal vein ascends the leg, it becomes the
olasank [31]

Answer:

D. Femoreal vein.

Explanation:

Close to the popliteal artery, the popliteal vein extends and transports blood from the knee (and also the muscles from the thigh and calf) once again up to the heart. This vein has its origin in the joint between both the anterior and posterior tibial veins, proximal to the knee.

Also, the popliteal vein starts its extension from the popliteal artery, which can be found behind the knee, and the drainage of the peroneal vein is performed by it prior to reaching the knee joint, where the popliteal vein becomes known as the femoral vein.

HELP PLEASE I HAVE A WEEK LEFT OF SCHOOL I DONT WANNA FAIL
Oksana_A [137]

Answer:

I am too lazy to do this, but I am assuming you were supposed to do this in class. I will give you ideas.

Why is soil important?  Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites.

What is soil erosion?  Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

what human activities are responsible for soil erosion happening at advance rates?     Ploughing, unsuitable agricultural practices, combined with deforestation and overgrazing, are the main causes of human-induced soil erosion

What are some effects on soil loss?  The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

What can be done to prevent soil erosion?   Maintaining a healthy, perennial plant cover.

Mulching.

Planting a cover crop – such as winter rye in vegetable gardens. ...

Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

Explanation:  Hope this helps and have a great day
