The eardrum part of the middle ear vibrates in response to incoming sound waves, and three small bones in the middle ear receive these vibrations. The names of these bones are malleus, incus, and stapes.
Which component of the ear moves sound with the ossicles when it vibrates?The ossicles were set in motion by the eardrum's vibrations. In reality, the ossicles are the tiniest bones in the human body.
What component of the ear is vibrating and transmitting the vibration to the three small bones?Eardrum vibrations occur. The three little bones in the middle ear known as the ossicles are thus exposed to the vibrations. The ossicles make the sound louder.

bicoid is a gene that produces a porphogen. what results when there is a high concentration of the bicoid protein in a devlopoing [mebryo
A high concentration of bicoid protein at the opposite ends of a developing Drosophila embryo would result in the development of a two-headed fly.
Bicoid acts as a morphogen during Drosophila development. Thus, BCD mRNA is maternally located at the anterior pole of the embryo and Bcd forms an anterior/posterior gradient that functions in a concentration-dependent manner. Both functions require a homeodomain that recognizes.
DNA motifs on target gene enhancers and specific sequence spacing of her 3 untranslated regions of the tail mRNA. Female embryos with the bicoid mutation lack the head and thorax replaced by a posterior telson. Embryos lacking both maternal and zygotic hb show reduced and anterior shifts of ems and btd expression at the blastoderm stage.

What makes up the sides of the backbone of DNA?
and
What makes up the inside or the steps of a DNA molecule?
Answer:
The sides of the backbone of DNA are made up of alternating sugar (deoxyribose) and phosphate groups. The inside of the DNA molecule, or the "steps" as you put it, consists of the bases: adenine, guanine, cytosine, and thymine. These bases pair up with each other in specific ways: adenine always pairs with thymine, and guanine always pairs with cytosine. This is what gives DNA its unique double-helical structure and allows it to store genetic information.
Answer:
The backbone of a DNA molecule consists of the phosphate groups and the deoxyribose sugars, whereas the base of the DNA molecule consists of nitrogenous bases, therefore, the backbone of DNA is made up of phosphate groups and pentose sugars. Adenine is a part of the base of the molecule.
which statement is false about the skeletal alterations caused by chronic renal failure? when the glomerular filtration rate (gfr) declines to 25% of normal
A adequate amount of parathyroid hormone can no longer be secreted by the parathyroid gland .
GFR declines when the macula densa notices an increase in the concentration of NaCl in the renal filtrate.By monitoring filtrate osmolarity, the macula densa controls the body's blood pressure. If it falls too low, it causes the kidney's afferent arterioles to constrict, increasing pressure at the glomerulus and increasing glomerular filtration rate.Increased sodium chloride supply to the macula densa causes the production of adenosine, which causes vasoconstriction when it binds to the afferent arteriole. GFR is reduced as a result of the vasoconstriction.It is thought that the distal tubule fluid's sodium content and maybe the speed at which the fluid passes through them cause the macula to react.

. why do you think four molecules of catecholamine neurotransmitters are generally bound to each molecule of atp?
In four neurotransmitter molecules the catecholamine is bound to each molecule of ATP because the synaptic vesicles and synaptic granules on the neurotransmitter contain adenosine triphosphate with a molar ratio of catecholamine to ATP of approximately 4:1.
Hormones that play a role in the nervous system are catecholamines in the form of epinephrine (adrenaline) and norepinephrine (noradrenaline). The adrenal medulla contains chromaffin granules (organelles in cells) which function for the biosynthesis, absorption, storage, and secretion of catecholamines.
Other compounds contained in these granules are ATPMg2+, Ca2+, Dopamine-β-hydroxylase (DBH), and the protein chromogranin. Catecholamines enter the granules by a transport mechanism with an ATP-dependent ratio of catecholamines : ATP = 4 : 1. Norepinephrine is stored in the granules, can leave and undergo methylation of the N-terminal end of the protein to form norepinephrine and then enter new granules.
