Answer:

Ellipse

Explanation:

Earth's orbit (and the orbit of other planetary bodies) are not perfect circles - they are in fact elliptical.

Diffusion is an important process in animals and plants.
Paraphin [41]

Answer:

Diffusion helps animals in respiration. The cells in an animal's body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells. As cells use up the glucose and oxygen they produce waste chemicals and carbon dioxide.

Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. This helps the plants to photosynthesize and produce more food.

Example for animals: Animals using glucose and oxygen in diffusion.

Examples for plants: Plants using carbon dioxide to photosynthesize.

Succession occurs when environmental factors affecting an ecosystem change. True or False
zhannawk [14.2K]

Answer: True

Succession is the phenomena in which changes in the biotic and abiotic factors of the environment leads to change in the ecosystem. A succession is a process in which a biological community is replaced by another biological community until a mature ecosystem is formed this process is influence by environmental factors. Primary succession is the primitive environment where no biotic community previously existed it is followed by secondary and subsequent succession were life forms develop and form an ecosystem. Some of the environmental factors are:

Topographical : These are the change in the region or habitat were succession occurs. Landslides, volcanic eruption, glacier melting etc. are the examples , as these topographical changes can bring reformation of the landscape. The disturbance caused by these topographical changes will allow the disturbance tolerant species to repopulate the habitat.  This can be a transition from primary to secondary succession.

Soil : It is an abiotic factor.The growth of the plants requires suitable soil conditions. The type of soil will affect which species will inhabit the area. The soil moisture and pH greatly affect the number of plant species in an area.

Climate : It can influence the direction of succession. Climatic factors includes rain, wind etc. For example a region lacking proper rainfall the species will be tolerant to dry and drought conditions. The region with heavy rainfall, the species will be more tolerant to moisture. Wind being a climatic factor can cause wind erosion affect the soil quality. Wind can lead to heavy forest fires can therefore, wiped out community.

What is the correct way to analyze a term that means "softening of the cartilage"?
Ber [7]

Chondromalacia is the synonymous of the cartilage softening (chondro = cartilage, malacia = soft). It's a pathology of softening affecting the joints and more particularly those of the knee (kneecap and femur).

This anomaly can be observed in several circumstances:

• the first is that of direct trauma. It is the cartilaginous lesion occurring before the fracture (fissure) of the cartilage.

• the second is that of common osteoarthritis. It is highly likely that the first stage of osteoarthritis begins with edema (swelling of the cartilage or closed chondropathy) that makes the cartilage less resistant and more vulnerable; this soft cartilage can then crack on its surface (open chondropathy) and these cracks will be more difficult to heal.
