if the values for both mass and volume double, the value of the density will be?

Answers

Answer:

Stays the same.

Explanation:

Density = mass/volume

So if :

M/V = D

And if we were to double mass(M) and volume (V)

2M/2V = D

It will stay the same because the 2 and 2 would cancel out and we'd get the same density as the original value.

Glucose is an organic compound produced during the process of photosynthesis. Select the word below that best describes glucose.

B. Nucleotide
A. Polypeptide
C. Monosaccharide
D. Steroid

Answers

Answer:

C. Monosaccharide

Explanation:

Glucose is an carbohydrate molecule with the chemical formula, C6H12O6. It is one of the simplest form of carbohydrates called MONOSACCHARIDE OR SIMPLE SUGAR. This means that it has a single ring in its chemical structure. Other monosaccharides are fructose, galactose etc.

As stated in this question, Glucose is produced as energy source during the process of photosynthesis in plants i.e. the combination of carbon dioxide (CO2) and water (H2O).

g Identify the statements that accurately describe how hydrogen ion concentration relates to energy production in oxidative phosphorylation. Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space. The pH in the mitochondrial matrix is lower than the pH in the intermembrane space. Energy is generated as a result of the difference in hydrogen ion concentration between the intermembrane space and the cytoplasm. Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain. Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.

Answers

Answer:

- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.  

- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.  

- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.

Explanation:

Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.

Potatoes are native to Monuntainous areas of Bolivia and Peru in South America, but are now grown widely around the world. What kinds or environmental conditions do you think areas must have in common for a crop to be successful around the world?

Answers

Answer:

Potatoes grew in the mountainous regiosn of Bolivia and Peru because they prefers such climates. Climates that are on the cold side but not so cold that the ground would be frosty. A temperature of between 60° to 70°F is considered ideal and anything above 80° F is considered too warm for them even though they have been known to adapt.

The soil should be very mildly acidic with a pH of between 5.0 to 5.5. Potatoes prefer to be grown in the full presence of the sun in well drained soils that are not compact or constantly wet.

The Environmental conditions are therefore;

Use a Punnett's squares to show a monohybrid cross between pure breeding parents of tall (T) and dwarf (t) pea plants.
The tall trait is dominant and thus is represented by the uppercase letter "T". The dwarf trait is recessive and is represented by
to lowercase letter "t".

Answers

Answer/Explanation:

True breeding means the parents have two copies of the same allele (two of the same letter)

That means the monohybrid cross is TT x tt

      T            T

t      Tt          Tt

t      Tt          Tt

All the offspring have one copy of each and are Tt. Tall is dominant to dwa rf. So all the offspring will be tall.

Valid Expressions are; t = ∛(d²/va), a = d/t², a = √(vd/t³), v = at

while the Invalid expressions are;  v = a/t and  d = at

Explanation:

Given expressions

1) v = a/t

2) t = ∛(d²/va)

3) d = at

4) a = d/t²

5) a = √(vd/t³)

6) v = at

First we get our units of parameters

V = m/s, t = sec, d = m, a = m/s²

so

1)

v = a/t

we substitute in our units of parameters

v = m/s² / s = m/s² × 1/s = m/s³

v ≠ m/s³

therefore it is false

2)

t = ∛(d²/va)

we substitute

t = ∛(m² / m/s × m/s²)

t = ∛(m² / m²/s³)

t = ∛(s³)

t = s

correct, the expression is true

3)

d = at

we substitute

d = m/s² × s

d = m/s² × s/1 =  ms/s² = m/s

d ≠ m/s (because d = m)

so expression is false

4)

a = d/t²

we substitute

a = m / s² = m/s²

correct

the expression is true

5)

a = √(vd/t³)

we substitute

a = √(m/s×m / s³) = √(m²/s / s³) = √(m²/s × 1/s³)  = √(m²/s⁴) = m/s²

so a = m/s²

correct

the expression is true

6)

v = at

we substitute in the units

v = m/s² × s = m/s² ×s/1 = ms/s² = m/s

v = m/s

correct

the expression is correctValid Expressions are; t = ∛(d²/va), a = d/t², a = √(vd/t³), v = at

t = ∛(m² / m²/s³)

t = ∛(s³)

t = s

correct, the expression is true

3)

d = at

we substitute

d = m/s² × s

d = m/s² × s/1 =  ms/s² = m/s

d ≠ m/s (because d = m)

so expression is false

Allen Dexter, a 19-year-old college student, was rock climbing when he fell 30 feet to the ground. Paramedics arriving at the scene found him lying in the supine position, unable to move any extremities and complaining of neck pain. He was alert and oriented to his current location and the details of his fall. He complained that he could not feel his arms and legs. His pupils were equal and reactive to light. His vital signs revealed a blood pressure of 110 / 72 and a heart rate of 82 beats per minute. Breathing was steady but shallow. The paramedics immobilized his neck and transported him to the trauma center. Upon examination Allen had some sensation in his arms, but could not localize touch or describe texture. He was able to raise his shoulders and tighten his biceps brachii slightly in each arm, but could not raise either arm against gravity. His lower extremities were flaccid, despite attempts to move them. Vital signs were taken again at the hospital and were as follows: blood pressure=94 / 55; heart rate=64; respiratory rate=24 (with shallow breathing). His oral temperature was 102.2 degrees F. His color was dusky and his skin was warm and dry to the touch.

X-rays taken upon arrival revealed a fractured vertebra at the C5 level. A chest X-ray showed a decreased lung expansion upon inhalation. Blood tests were normal, with the exception of a respiratory acidosis (blood pH = 7.25). The neurosurgeons immobilized his neck by inserting tongs into the skull above the ears to hold his neck in a position so that no further injury could occur. Allen was transferred to intensive care and his condition was stabilized.

A physical examination four days later revealed normal vital signs and no change in his arm strength or sensation, but also marked spasms and exaggerated stretch reflexes of the lower extremities. He also had urinary incontinence which required the placement of a Foley catheter connected to a urine collection bag.

Required:
a. Why did the paramedics apply a cervical collar, place him on a back board and immobilize his head?
b. How would the paramedics test Allen's pupils reaction to light and what would the anticipated normal response be when exposed to light?
c. List his vitals on the scene of the accident and compare them to his vitals at the hospital when he arrived and four days post surgery.
d. What did the x-rays reveal?
e. What did blood tests reveal?
f. Describe the surgical procedure that was performed?
g. What were the physical findings four days post op?

Answers

Answer:

Explanation:

A cervical collar was used to avoid movement and prevent further damage incase he has a fracture.

light is focused in one eye,the pupil will constrict as a respond to the light flashed. It is repeated Again and observed.

The vitals were normal until he had the accident as the patient reached hospital his vitals were abnormal he had achycardia, severe hypotension, increased temperature and shallow breathing which is an indicator of C5 injury. After the surgery and the patient was treated he stabilises and achieved his vitals normal ranges in day 4 of admission.

The X ray result shows he has fracture of the 5th cervical bone.

The blood test shows he has a decreased pH level and an alteration in

his breathing pattern shows he has respiratory acidosis

Cranial tongs was uses to immobilize the neck and prevent it from moving it also aid healing

After the operation it was revealed that he has a damage on both sides of of his 5th Cervical bone which has lead to loss of sensation and strength in his upper arms and lower .It leads to incontinence in urine.

You have learned that heat moves from warm areas to cooler ones. In solids, heat is transferred by the physical touching of molecules. This type of heat transfer is called conduction. Some materials, like metal, conduct heat better than other materials. In fluids (liquids and gases), heat is transferred by convection currents caused by differences in density.

MATERIALS

Answers

Pt. 1

In gases and liquids, heat is usually transferred by convection, in which the motion of the gas or liquid itself carries heat from one place to another. ... If you boil water in a kettle, the heat is transferred through convection from the fire to the pot.

Pt. 2

This motion of fluids is called convection. In the set of bottles where the hot water was above the cold water, the cold water was already on the bottom, so there was no convection.

Pt. 3

When the bottle was put into the cold water, the air in the bottle contracted, taking up a smaller space in the bottle. The sides of the bottle pushed in when the air inside controlled

Answers

It's D :) hope this helps <3

DNA is a nucleic acid that gets duplicated by replication. The single strand of DNA is made of nitrogenous bases attached to a sugar-phosphate backbone. Thus, option D is correct.

What is DNA?

DNA is the abbreviated form of deoxyribose nucleic acid that is the major molecule involved in inheritance and genetics. DNA undergoes a replication process where the two daughter strands, semiconservative in nature are produced.

The DNA is a polymer composed of the sugar (deoxyribose) - phosphate backbone along with nitrogen bases that include adenine, thymine, cytosine, and guanine. The phosphodiester bond, hydrogen bond, and glycosidic bonds are involved in interlinking the structural framework.

Therefore, option D. the sugar-phosphate backbone linked to the nitrogenous bases makes the structure of DNA molecule.
