Biology
1 answer:
grigory [225]3 years ago
4 0

Answer: Dark energy and dark matter describe proposed solutions to as yet unresolved gravitational phenomena. So far as we know, the two are distinct. Dark matter originates from our efforts to explain the observed mismatch between the gravitational mass and the luminous mass of galaxies and clusters of galaxies.

Which phase of the cell cycle is the least common process of mitosis and what could be the reason?
AveGali [126]

Answer:

In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes. In telophase, 2 daughter nuclei form. The nuclear envelope beings to reappear.

All of the following protect the skin and mucous membranes from infection except
leva [86]

The question is incomplete. Th ecomplete question is as following:

All of the following protect the skin and mucous membranes from infection EXCEPT  

A) multiple layers of cells.

B) tears.

C) saliva.

D) HCl.

E) the "ciliary escalator."

Answer: D) HCl.

Explanation:

  • The epidermis, the outer layer of the skin provides waterproofing and serves as a barrier to infection and other laers also sustain any type of injury.  
  • Tears wash out foreign bodies which enter the eye. In addition, tears contain a substance called lysozyme which has an antibacterial function and works to prevent microbial invasion and infection.  
  • Saliva protects against infection, especially via the innate immune system. This mechanism is an important first-line protection against bacterial and viral infection
  • The mucociliar escalator is within the conducting airways and is composed of mucus and cilia that transfer the mucus up and out of the lungs where it can be removed by coughing or swallowing,

Whereas HCL helps in the digestion process.

Hence, the correct option is D.

Suppose scientists determine that a set of genes is significantly more prevalent in murderers than in the population at large. W
forsale [732]

Answer:

No

Explanation:

<u>That a gene is common to all murderers in the population does not mean that murderers are not at fault for their crimes. </u>

<em>Having a gene that correlates with murder just gives one a genetic tendency but the environment and personal choice still have to influence the decision to commit the crime. In other words, one might have the genetic tendency to commit murder but still has to be environmentally enabled and the ability to choose to either do it or otherwise. Nature, nurture, and personal choice would have to synergistically work together for the phenotypic expression of such a gene. </em>
