Mycorrhizae, specialized symbiotic associations between the roots of plants and fungi, are characteristic of:_________
pogonyaev

Mycorrhizae, specialized symbiotic associations between the roots of plants and fungi, are characteristic of about 90% of all plants.

Mycorrhizal fungi are a symbiotic combination of fungi and plants. The term mycorrhiza refers to the role of fungi in a plant's rhizome, its root system. Mycorrhizae play an important role in plant nutrition, soil biology, and soil chemistry.

In mycorrhizal organization, the fungus resides in the root tissues of the host plant, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in extrinsic fungi.

The association is sometimes reciprocal. In some species or in specific cases, mycorrhizal fungi may have a parasitic association with the host plant.

Mycorrhizae are generally divided into ectomycorrhizae and endomycorrhizae. These two types are distinguished by the fact that mycelium of mycorrhizal fungi does not penetrate individual root cells while mycelium of endophytic fungi penetrates the cell wall and penetrates the cell membrane.

In 2016, Sub-Saharan Africa had a doubling time of 23.3 years.
Masja [62]

The correct answer is Option B: 3%.

In 2016, Sub-Saharan Africa, doubling time is 23.3 years, thus Growth rate is 3%.

<h3>What is doubling time?</h3>
  • The doubling time is the time taken by a population to double in its size.
  • This concept is applied to population growth, inflation, resource extraction, consumption of goods, the volume of malignant tumors, and many other things that tend to grow over time.
  • There is an important relationship between the percent growth rate and its doubling time known as “the rule of 70”: to estimate the doubling time for a steadily growing quantity, simply divide the number 70 by the percentage growth rate.
  • Therefore, Growth rate is 70 divided by doubling time (70/ doubling time).
  • Here, Doubling time= 23.3 years.
  • Growth rate= 70/23.3= 3%

As hominids evolved, their eyes increased in size and became more forward facing. Which of the following can be inferred from th
lisabon 2012 [21]
 The answer is Hominids became more dependent on vision over time and less so on their other senses.  <span>This statement is related to the general decrease in the importance of smell and the increasingly significant use of vision. The stereoscopic (three-dimensional) vision and the appropriate perception of the resulting depth enabled the development of visual acuity over time.</span>
