Leaf-tailed geckos have long, flattened bodies with triangular heads and broad leaf-like tails. The giant leaf-tail gecko, or common flat-tail gecko, is one of the larger species. They have large marbled eyes with red concentric stripes around the pupil on a silver, brown, or gold background. These lizards have mottling that varies in color from tan and green to gray and tan depending on the species.
They also have the ability to camouflage themselves not only with the shape and vegetation of the forest in which they live, but also with the colors of their surroundings. The fringe lobes of the mandible and the sides of the body are flattened against the surface and delineated. The increased surface area reflects and refracts light, breaking the line between the perimeter of the body and the surface below. These adaptations allow leaf-tailed geckos to be almost completely camouflaged from dry leaves and tree bark. The giant leaftail gecko lives in moist, intact forests in the lowlands at an altitude of 800 meters (about 2,625 feet). During the day, branches, logs and fallen leaves provide areas of camouflage for geckos to roost away from the sight of predators. increase. They also inhabit the rainforests of Madagascar's east coast, but there are no confirmed reports of the species living further south than the mainland town of Vondrozzo.
Thus, leaf-tailed geckos have long, flattened bodies, triangular heads, and wide, leaf-like tails.

neurotransmitters bind to , which are protein structures on the surface of the neuron cell membrane. a. neural receptors b. cell bodies
neurotransmitters bind to protein structures on the surface of the neuron cell membrane called as neural receptors
A. neural receptors.
neurotransmitters are the chemicals that are secreted by the pre-synaptic cell into the synapses of the two neurons which binds with the post-synaptic cell to transmit the action potential into the cell.
The various that are used as neurotransmitter are acetylcholine, histamine, serotonin, dopamine, etc.
the neurotransmitters are synthesized and stored in the vessels of pre-synaptic neuron. When an action potential arrives, the vessel merge with the membrane and releases the neurotransmitters.
They bind with the neural receptors of the other cell to generate action potential.

If four different vntr alleles have frequencies of 1 in 10, 1 in 20, 1 in 50, and 1 in 500 in a population of 250 million, how many people would have all four alleles?.
Answer:
50
Explanation:
There are 50 persons in the population that have this pattern, with an occurrence frequency for the 4 alleles of 1 in (10x20x50x500) = 1 in 5,000,000.
Variable numbers tandem repeats, called VNTRs, are the repetitive sections of the DNA strand. The fundamental benefit of STR fingerprinting over VNTR fingerprinting is that it just needs a tiny quantity of pure DNA and a short DNA sequence to carry out its activities. The main purpose of STR fingerprinting is to precisely identify a given individual's genes fingerprint. Moreover, the variable number of tandem repeats (VNTR), are brief sequences (between 20 and 100 bp) whose repetition numbers vary at particular loci in the genome among several animals, notably humans. VNTR sequences differ in length across individuals within the same species or group, hence they are frequently employed as molecular identifiers to identify people, map QTLs (quantitative trait loci), establish evolutionary connections between people/cultivars/lines, etc.

True or false life changes whether they are positive ir negative can cause stress
Answer: True.
Explanation:
It is true that life changes, whether they are positive or negative, can cause stress, so this statement is a true statement. It is more commonly known for negative things to cause stress, but positive things can cause stress too. This type of stress is sometimes known as eustress. Examples of eustress, or "positive" life changes causing stress, can include attending large events, dates, waiting for something exciting, etc.

A tissue is viewed using a microscope. the presence of tightly packed cells with a free surface and a basement membrane allows this tissue to be quickly identified as ____________.
A microscope is used to examine the tissue. This tissue is easily recognized as epithelial tissue because it contains densely packed cells with something like a free surface and just a basement membrane.
What does epithelial tissue do, and why?There are numbers of epithelial tissues in the human body. They make up the majority of the tissue in glands, line body cavities as well as hollow organs, and cover all of the body's surfaces. Protection, secretion, absorption, excretion, filtration, diffusion, as well as sensory reception, are just a few of the many tasks they carry out.
What components make up epithelial tissue?These proteins, which are primarily formed of claudins and occluding, are placed in a row close to the same apical surface of the epithelial cells. The basement membrane is the support for epithelial tissue. This same basal lamina and even the connective tissue beneath it make up its two components.

which of the following prenatal blood or laboratory tests helps determine immunity to german measles?
The prenatal blood or laboratory test that helps to determine immunity to German measles is Rubella titer.
German measles is also known by the name Rubella. It is a disease caused by a virus and is contagious. The transmission of the disease can be via contact with an infected person or inhaling the virus containing droplets. The general symptoms of the disease are: fever. runny nose, headache, cough, sore joints, etc.
Rubella titer is a diagnostic test that tests for the presence and the amount of the antibodies formed in the body against Rubella virus. If the test is positive that depicts that the person is immune to the disease and a negative result indicates that the amount of Rubella virus antibodies are less and the person can become infected.
