The trial natriuretic peptide(ANP) is a hormones that will not stimulate changes that lead to an increase in arterial blood pressure.
<h3>What is a arterial blood pressure?</h3>
This refers to the force that is exerted by the blood on the arterial wall.
Hence, the hormones that will stimulate changes that lead to an increase in arterial blood pressure includes the Antidiuretic hormone (ADH), Aldosterone, Angiotensin and Epinephrine
Therefore, the Option A is correct.

The internet connection types that is being used is DSL (Digital Subscriber Line).
<h3>What is
DSL (Digital Subscriber Line)?</h3>
DSL is a type of broadband internet service that uses existing copper telephone wires to transmit data. DSL can provide high-speed internet access, typically ranging from 1 Mbps to 100 Mbps, depending on the distance from the service provider and the quality of the wiring. DSL can also allow users to make analog phone calls over the same line at the same time, because DSL uses a different frequency band than voice signals. DSL requires a special modem that can separate the data and voice signals and connect to the computer and the phone.
Some advantages of DSL are:
- It is always-on, meaning there is no need to dial up or wait for a connection.
- It is relatively inexpensive and widely available in urban and suburban areas.
- It does not interfere with the normal use of the telephone line.
Some disadvantages of DSL are:
- It is not available in some rural or remote areas, where the distance from the service provider is too far or the wiring is too old or damaged.
- It can be affected by environmental factors, such as noise, weather, or electrical interference.
- It can have variable speeds and performance, depending on the traffic and congestion on the network."

Balance the combustion reaction:
a C₂H₂ + b O₂ → c CO₂ + d H₂O
Count the atoms on both sides of the reaction:
• C : 2a = c
• H : 2a = 2d
• O : 2b = 2c + d
Let a = 1; then c = 2 and d = 1, and it follows that
2b = 2•2 + 1 = 5
so that b = 5/2, and the balanced reaction is
1 C₂H₂ + 5/2 O₂ → 2 CO₂ + 1 H₂O
or, with integer coefficients,
2 C₂H₂ + 5 O₂ → 4 CO₂ + 2 H₂O
C₂H₂ has a molar mass of about 26.038 g/mol, so we have a starting amount of
(64.0 g) (1/26.038 mol/g) ≈ 2.46 mol C₂H₂
According to the reaction, we produce H₂O in a 1-to-1 ratio with the C₂H₂ that is burned up, so we end up with about 2.46 mol H₂O.
