<h2>Disease </h2>

Explanation:

  • Pathogenicity is the ability to produce disease in a host organism
  • Microbes express their pathogenicity by means of their virulence, a term which refers to the degree of pathogenicity of the microbe
  • The relationship between a host and a pathogen is dynamic, since each modifies the activities and functions of the other
  • The outcome of such a relationship depends on the virulence of the pathogen and the relative degree of resistance or susceptibility of the host, due mainly to the effectiveness of the host defense mechanisms
  • Hence, general requirements for any organism to cause disease within a host are: evasion of host defenses , gaining access to the host via a portal of entry, adherence to host tissues

Through which tissue do sugars get transported to reach the leaves during growth and reproduction?
nika2105 [10]

The correct  answer is Phloem

Explanation:

Phloem is a transport tissue of vascular plants. It is used for transport of food and nutrients, so sugar is definitively brought by phloem.Other choices cannot be right because collenchyma and parenchyma are ground tissues, while xylem is the carrier tissue similar to phloem but worked for a conveyor of water and minerals.

The synaptonemal complex is Group of answer choices a network of microtubules that forms the spindle apparatus. a region of high
DerKrebs [107]

Answer:

a network of proteins that holds homologues together.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

The synaptonemal complex is a network of proteins that holds homologues (homologous chromosomes) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

Other factors being equal, which sensory stimulus is least likely to lead to sensory adaptation?
valentina_108 [34]
The correct answer is: the wail of a loud car alarm. 
Sensory adaptation is a term that refers to the changes that stimuli can trigger on the sensory receptors. The process involves changes in the receptors' sensitivity and it is believed that all of the senses exhibit this adaptation. In particular, the sense of touch can quickly adapt to hot and cold stimulation, but not when the stimulus is extremely intense (such as too hot or too cold). Also, our olfactory sense presents the characteristic of odour fatigue. A prolonged exposure to a specific smell leads to a temporary inability to sense this smell and this is a type of sensory adaptation. Finally,
our hearing undergoes a sensory adaptation as well, but not when it comes to sudden, unexpected and instantaneous loud noises. That is why the wail of a loud car alarm will be the least likely to cause sensory adaptation.
