How dose observed pattern of magnetic reversals supports the theory of sea floor spreading

Biology

attashe74 [19]2 years ago

Answer:

When the Earth's magnetic field reverses, a new stripe, with the new polarity, begins. Such magnetic patterns led to recognition of the occurrence of sea-floor spreading, and they remain some of the strongest evidence for the theory of plate tectonics.

When watering her plants, Stela adds enough water to the soil to completely wet it. How will this help in plant growth?

1pt Place the following steps in the correct order:
Hoochie [10]

Answer:

The delivery of the paternal genome to the egg is a primary goal of fertilization. In preparation for this step, the nucleus of the developing spermatozoon undergoes extensive morphological and biochemical transformations during spermatogenesis to yield a tightly compacted sperm nucleus. These modifications are essentially reversed during fertilization. As a result, the incorporated sperm nucleus undergoes many steps in the egg cytoplasm as it develops into a male pronucleus. The sperm nucleus (1) loses its nuclear envelope, (2) undergoes nucleoprotein remodeling, (3) decondenses and increases in size, (4) becomes more spherical, (5) acquires a new nuclear envelope, and (6) becomes functionally competent to synthesize DNA and RNA. These changes are coordinate with meiotic processing of the maternal chromatin, and often result in behaviors asynchronous with the maternal chromatin. For example, in eggs fertilized during meiosis, the sperm nucleus decondenses while the maternal chromatin remains condensed. A model is presented that suggests some reasons why this puzzling behavior exists. Defects in any of the processes attending male pronuclear development often result in infertility. New assisted reproductive technologies have been developed that ensure delivery of the sperm nucleus to the egg cytoplasm so that a healthy embryo is produced. An emerging challenge is to further characterize the molecular mechanisms that control sperm nuclear transformations and link these to causes of human infertility. Further understanding of this basic process promises to revolutionize our understanding of the mystery of the beginning of new life.

Progressive degeneration of the retina that affects night and peripheral vision is known as?
natka813 [3]

Progressive degeneration of the retina that affects night and peripheral vision is known as retinitis pigmentosa.

<h3>What is retinitis pigmentosa?</h3>
  • A collection of uncommon eye conditions known as retinitis pigmentosa affect the retina.
  • Retinitis pigmentosa causes the retinal cells to gradually deteriorate over time, resulting in visual loss.
  • RP is a hereditary condition that affects people at birth.
  • The term "retinitis pigmentosa" (RP) refers to a group of illnesses that affect the retina's light-sensitive cells and impair vision.
  • There is currently no medication to stop the course of the disease, nor is there a cure.
  • Night blindness and tunnel vision are symptoms.
  • Retinitis pigmentosa has no specific treatment.
  • However, using UV sunglasses to protect the retina in your eyes may help postpone the onset of symptoms.
  • For people with very advanced disease and severe visual loss, a retinal prosthesis (artificial retina) has been developed.
