Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

Nuclear envelope forms at each pole spindle dissolves chromosomes uncoil. True or False
Doss [256]

Answer:

True.

Explanation:

There are four phases which occur during karyokinesis, these are -

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase

Telophase is the last phase of karyokinesis. The main events that occur during telophase are-

  • Uncoiling of chromosome occurs
  • Chromatin is formed
  • Spindle breaks down
  • Nuclear membrane or nuclear envelope if reformed

Thus it is clear that the events that are mentioned in the question denote truly about the Telophase.

How Neurons Work (1 of 3): Neuron Structure and Resting Potential (BioFlix tutorial)?
fiasKO [112]

 A neuron is nerve cells that transfer information within the body, chemically over short distances, using electrical signals over long ones.

   As it turns out, most resting neurons are permeable to Na+ and CL- as well as K+. K+ will try to drag the membrane potential toward its (positive) equilibrium potential, while NA+ try to drag the membrane potential to its negative equilibrium potential.

The real membrane potential will be between NA+ and K+ of equilibrium potential<span>. However, it will be closer to the equilibrium potential of the ion type with higher permeability.</span>

The most important adaptive advantage associated with the filamentous nature of fungal mycelia is
MAVERICK [17]

Answer:

d. an extensive surface area well suited for invasive growth and absorptive nutrition.

Explanation:

Fungi have an extracellular nutrition. These means enzymes are released to environment to start degrading macromolecules which can be later be absorbed (absorptive nutrition) through cell membranes. Having multiple spots (bigger surface area) through which it can nurture speeds up the rate at which it can grow leading to a faster growth and higher competition over resources.

Can we drink too much water?
Dennis_Churaev [7]

Answer:

Although uncommon, it's possible to drink too much water. When your kidneys can't excrete the excess water, the sodium content of your blood is diluted (hyponatremia) — which can be life-threatening.
