How are pathogens spread by contaminated objects

How do scientists use seismic waves to determine the interior structure of Earth?

Rom4ik [11]

<span>Much of our understanding of the basic structure and composition of Earth and the other planets in our solar system is not strenuously debated. We can infer a surprising amount of information from the size, mass and moment of inertia of the planets, all of which can be determined from routine astronomical observations. Measurements of surface chemical composition, either by direct sampling (as has been done on Earth, the moon, and Mars) or through spectroscopic observations, can be used to estimate elemental abundances and the degree of chemical differentiation that occurred as the planets condensed from the solar nebula. Remote observations of the gravitational field can be used to understand how a planet's mass is distributed, whereas the strength and shape of the magnetic field provides some constraint on the structure of a metallic core. The specifics of structure and composition, however, are much more debatable. And it is these details that tell us a much more extensive and ultimately more interesting story about the internal dynamics of the planets and their evolution. As a result, trying to determine them is frontier research in almost all fields of earth and planetary science.

Nancy is reading the doctor's orders for Ms. Brighton, a 72-year-old with COPD, congestive heart failure, Type 2 diabetes, high

MatroZZZ [7]

Answer:

Question the order and explain the potential problems

Explanation:

It should be understood that COPD means Chronic Obstructive Pulmonary Disease, which can be described or known to be a common disease of the lung. And it always make it hard to breath.

Now, what Nancy needed to do in such situation is to ask question as to why the drug or medication should be taken by Ms Brighton. At the course of doing this, Nancy should let them know the potential problem the patient will have if she took the medication.

In this case, Nancy should make sure that necessary correction was made.

How many atp equivalents are consumed in the conversion of each of the following to a glucosyl residue in glycogen?

Nina [5.8K]

<h3><u>Answer;</u></h3>

Dihydroxyacetone phosphate - 1

Fructose-1,6-bisphosphate - 1

Pyruvate - 13

G-6-P - 1

<h3><u>Explanation;</u></h3>

1) Dihydroxyacetone phosphate = 1

G1P + GTP --> UDPG + PPi two P is equivalent to 2 ATP --->2 ADP + Pi) Therefore, two ATP equivalents - but UDP is the product and only one P needed

2 DHAP --> F1,6-BP -->F6P --> G6P -->G1P -->UDPG --> glucosyl residue

2) Fructose 1,6-bisphosphate = 1

3) Pyruvate = 13

2 pyr + 2 ATP --> 2 OAA

2 OAA + 2 GTP --> 2 PEP

2 PEP --> 2 2PG --> 2 3PG

2 3PG + 2 ATP --> 2 1,3 BPG

2 1,3 BPG + 2 NADH --> 2 G3P

2 NADH = 6 ATP

2 G3P --> DHP + G3P --> FDP -- > F6P + P

F6P --> G6P --> G1P

G1P + UTP --> UDPG + PP

4) Glucose-6-phosphate = 1

G6P -->G1P G1P + UTP --> UDP-GLC + 2 Pi

UDP-Glc + glycogen --> glycogen+ 1 Glc

Tillage can release pollutants in the soil and

Snezhnost [94]

Tillage can release pollutants in the soil and increase erosion by the acceleration of the soil and wind speed.

<h3>How doesTillage can increase erosion ?</h3>

Tillage can split soil structure, pace the decomposition and lack of natural matter, boom the hazard of erosion, break the habitat of useful organisms and reason compaction.

Each of those capability effects negatively effect soil fine. A soil's overall performance is immediately associated with a soil's fine or health. Since tillage breaks the soil, it disrupts soil structure, accelerating floor runoff and soil erosion. Tillage additionally reduces crop residue, which assist cushion the pressure of pounding raindrops.
