Selective adaptation is when we view a stimulus with a specific property, and the neurons tune to that property fire, eventually becoming fatigued.

Neurons tune to a particular attribute fire when we see a stimulus with that property; over time, this firing fatigues the neurons or causes them to adapt. The neuron's firing rate drops due to this adaptation and fires less often when the same stimulus is provided to it again right away.

For instance, a page of plain black text on a white backdrop will undoubtedly capture your attention and make it easier for you to identify important information. However, if you keep viewing pages and pages of mainly neon pink highlights, you'll probably grow accustomed to them, and they will eventually stop drawing your attention.

Achondroplasia is an autosomal dominant genetic disorder in humans. If a man with Achondroplasia ( heterozygous) and a normal wo
tresset_1 [31]

Answer and Explanation:

Achondroplasia is a form of dwarfism that affects the formation of cartilage; early in development, most of the skeleton is comprised of cartilage. Cartilage is a type of flexible, tough tissue; in achondroplasia ossification (conversion of cartilage to bone) is affected. Symptoms include an enlarged head, shorter upper and lower limbs, and limited motion at the elbow.

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding.

For this cross...

Assuming Achondroplasia= dominant

Parent generation or P generation:

gametes: An → Achondroplasia dominant (A), No Achondroplasia recessive (n)

Heterozygousity describes the allelic makeup; these traits comprise two varying forms of a  gene. However, homozygous traits comprise identical forms of the gene.

Male: An  →  with Achondroplasia

Female: nn → without Achondroplasia

genotypes and phenotypes for parent and offspring...

Assuming heterozygousity of the male , for the cross

P generation:                         An × nn

                          Achondroplasia   × No Achondroplasia

F1 generation:

genotype:                      An × nn       ...(from punnet square)

phenotype:          2 with Achondroplasia ; 2 without

∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with Achondroplasia ; 2 without

increasing intracellular cAMP leads to smooth muscle relaxation by: Group of answer choices inhibiting IP3 channels, leading to
kirza4 [7]

Answer:

1. Inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction.  

2. Increasing the relative activity of MLCP, leading to a decrease in tension.

3. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry.

Explanation

In smooth muscle, cyclic AMP (cAMP) mediates relaxation because cAMP inhibits a specific kinase required for myosin light chain protein (MLCP) phosphorylation, thereby triggering contraction in the smooth muscles. It has been shown that cAMP inhibits 1,4,5-trisphosphate (IP3)-dependent calcium ions (Ca 2+) release by activation of the cGMP-dependent protein kinase (PKG). PKG proteins act to modulate Ca2+ oscillations by stimulating sarcoplasmic Ca2+-ATPase membrane proteins, increasing Ca2+ in the sarcoplasmic reticulum stores and Ca2+ efflux from the cells, and activate voltage-gated potassium (K) channels, thereby leading to membrane hyperpolarization and reducing Ca2+ entry through Ca2+ channels.

Which part of an individual villus forms part of the lymphatic system and absorbs fats from the lumen of the small intestine?
Lostsunrise [7]
I believe the answer is the lacteals. 
Lacteals are structures that are in the middle of each villi; they are lymphatic capillaries that absorbs dietary fats in the villi of the small intestines. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids and monoglycerides. The lacteals merge to form larger lymphatic vessels that transport chyle to the thoracic duct where it is emptied into the blood stream at the subclavian vein.
