What do the following two equations represent?<br> 5x +y = 3<br> . 10x + 2y = -6
cupoosta [38]

Answer:

Choose distinct parallel lines.

Explanation:

They represent two parallel lines. The slopes are going to be the same in each line . Put the x value on the opposite side of the equal sign.

y = - 5x + 3           The slope is - 5

10x + 2y = - 6        Subtract 10x from both sides

2y = - 10x - 6         Divide by 2

y = -10x/2 - 6/2

y =-5x - 3

That minus three is the problem. You have 2 different y intercepts. That means that you have 2 parallel lines.

Describe the neural and renal mechanisms that control blood pressure.
Andrei [34K]

Answer:

The autonomic nervous system is the main neural regulator of circulation and blood pressure in the short term and beat by beat and exerts its function through various reflexes that regulate vasomotor tone, heart rate and cardiac output. At the renal level, the renin–angiotensin–aldosterone system is possibly the most important in the maintenance of arterial homeostasis.

Explanation:

Blood pressure is regulated by a series of interrelated autonomic systems and humoral reflexes, which continually adjust the determining elements of the system (heart rate, stroke volume, total peripheral resistance and circulating volume).The effective circulating volume is controlled by a series of reflex systems, which obtain information about the perfusion pressure (baroreceptors in the carotid bulb and aortic arch), plasma osmolarity (hypothalamus) and urinary sodium (distal tubule).The kidney has its own self-regulatory mechanisms. The reduction in renal blood flow is detected at the level of the mesangial cells of the juxtaglomerular apparatus, starting the renin-angiotensin system. The increase in angiotensin II produces on the one hand local vasoconstriction, and on the other hand stimulates the production of aldosterone by the adrenal cortex with the consequent tubular reabsorption of sodium and water.Antidiuretic hormone or vasopressin (released from the hypothalamus by stimulation of arterial baroreceptors and also by stimulation of angiotensin II) also acts at the renal level, which acts as a powerful and water-saving vasoconstrictor in the distal tubule.

Now, assume the individuals with the filled symbols in the kindred have the O blood type, whereas all the individuals with the o
jek_recluse [69]

Answer:

When we talk about the inheritance of traits, or the passage of traits from parents to future generations down the line, we are not just talking about the visual (phenotypical) expression of those traits, but also, their underlying explanation, which is the genotype. A genotype is basically how the genes of the parents combine in such a way that the children inherit a set of traits from the parents, and express them phenotypically, or not.

In the case of blood types, we have four phenotypic groups: A, B and O. Each one of these types is characterized by the underlying set of genes that are responsible for what is expressed. While the O blood type presents a genotype ii, which is recessive, the A and B types will have the following genetic patterns: Ia Ia, or, Ia i (characteristic of the O genetic material) for the A type and: Ib Ib, or Ib i, for the B type. When there is a genetic conjugation from parents genetic material, regarding blood type, we would have these sets of genes combining. In most of the possible combinations genetically speaking, we have the recessive i gene appearing, including in the A and B dominant blood types. This means that when crossed, there will always be a chance of at least one offspring presenting the O blood type, even if one of the parents is dominant A, or B.

In answer: it is the fact that all three types present the recessive allele i, typical of the O blood type, that when pairings of genes happen between parents, the genetic characteristic of the O type may present itself in a dominant fashion, instead of the usual recessive pattern.
