slava [35]3 years ago

Answer: The ampullae of Lorenzini are special sensing organs called electroreceptors, forming a network of jelly-filled pores. ... The ampullae pores are plainly visible as dark spots in the skin. They provide fish with an additional sense capable of detecting electric and magnetic fields as well as temperature gradients. The skate, a cartilaginous fish related to sharks and rays, possesses a unique electrosensitive sensory organ known as the ampullae of Lorenzini (AoL). This organ is responsible for the detection of weak electric field changes caused by the muscle contractions of their prey. brainliest

How many chromosomes does a child inherit from his or her parents
pochemuha

Ans.

In humans, there are total of 46 chromosomes in each cell that show 23 pairs of chromosome. During reproduction, meiosis occurs in germ cells that leads to formation of daughter cells or gametes that contain half of the chromosomes as present in parent cells. Thus, each gamete (either male or female) contains 23 chromosome.

During fertilization, fusion of male gamete or sperm(with 23 chromosomes) and female gamete or ovum(with 23 chromosomes) to form zygote that develops into multi-cellular offspring with 46 chromosomes.

Thus, 'a child inherit 46 chromosomes from his or her parent (23 chromosomes from each parent).'

<h3>What is the role of the oral dentist?</h3>

Tooth extractions are carried out by dental and oral specialists for various reasons. A painful tooth or a tooth that has been significantly affected by decay may be the problem. Sometimes a dentist will extract a tooth to make room for dental prostheses or other devices.

When the situation becomes increasingly complicated, an oral expert rather than a dental professional may need to extract a tooth. They typically remove wisdom teeth or third molars.

The dental professional or specialist will initially numb the tooth to gradually relax the patient. Even though tooth extraction may still be distressing, it may be essential for relieving dental pain and preventing further problems.

Arrange the following steps for contraction in the correct sequence.
Kryger [21]

Answer:

Explanation:

Muscle contraction is stimulated by the movement of an action potential moving along a nerve fiber to the muscles. This event follow some series of process before being stimulated.

1. The impulse arrives at the synapse and travels through the transverse tubules.

2. The muscle impulse reaches the sarcoplasmic reticulum and calcium is released.

3. Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.

4. Tropomyosin molecules bind to exposed active sites, linking actin and myosin.

5. Thin filaments are pulled over the thick filaments.

6. The muscle fiber shortens and contracts.
