the blood speed in a normal segment of a horizontal artery is 0.15 m/s. An abnormal segment of the artery is narrowed by an arteriosclerotic plaque down to one fifth its normal cross sectional area. What is the difference in blood preassures between the normal and constricted segments of the artery. The density of the blood is 1060

Answers

Answer 1

Answer:

286.2  pa

Explanation:

Blood speed in a normal segment of a horizontal artery ( v2 ) = 0.15 m/s

Density of blood = 1060 kg/m^3

Normal sectional area = A2

constricted sectional area ( A1 )= 1/5 A2

Determine the difference in blood pressures between the normal and constricted segments

we will apply Equation of continuity     Av = constant

Δ p = 12 PV^2

     = 12 * 1060 * ( 0.15 )^2

     = 12720 * 0.0225  =  286.2  pa

attached below is a detailed solution of the Given problem

counted 10 waves passing by over a time
period of 1 second. What is the wave
frequency?

Answers

Answer:

it will be 10Hz ,because number of waves per second is 10 so we divide with 1second

The wave frequency of a wave which is passing by 10 waves over a time period of 1 second will be 10 Hertz (Hz).

What is Wave frequency?

Wave frequency can be defined as the number of waves which are passing through a fixed point in a given amount of time period. The SI unit for the wave frequency is the hertz (Hz), where 1 hertz is equal to 1 wave which is passing through a fixed point in the time period of 1 second. A higher-frequency wave has generally more energy than a lower-frequency wave with the same magnitude of amplitude.

The wave frequency of a wave which is counted to be 10 waves passing through a point in a time period of 1 second will be 10 Hertz (Hz).

In the citric acid cycle when an aldol addition occurs in a biological system, how do the amino acids contained in the Citrate Synthase enzyme help facilitate the reaction

Answers

Answer:

Citrate Synthase facilitates the formation of citrate by deprotonating Acetyl CoA and by protonating the carbonyl oxygen of oxaloacetate

Explanation:

Citrate synthase is a key enzyme in the citric acid cycle that functions to catalyze the formation of citrate from oxaloacetate and acetyl-CoA: acetyl-CoA + oxaloacetate + H2O >> citrate + CoA-SH (Coenzyme A ). This enzyme contains three amino acids at its active site that work together to catalyze the conversion of acetyl-CoA and oxaloacetate into citrate. This active site acts by abstracting (deprotonating) a proton from the alpha carbon of Acetyl CoA which serves as the nucleophile. Subsequently, the active site of the enzyme also protonates the carbonyl oxygen of oxaloacetate, which then suffers nucleophilic attack and thereby facilitating nucleophilic substitution reaction.

What is photosynthesis?

The sustainability of the significant number of life on Earth depends on photosynthesis. It is how almost all of the energy in the biosphere is made accessible to living beings.

All higher living forms on Earth consume photosynthetic organisms directly or indirectly since they are the primary producers that serve as the foundation of the planet's food webs.

Additionally, photosynthesis is responsible for producing virtually all of the oxygen in the atmosphere. The majority of creatures would vanish, there might soon be little food or other organic stuff on Earth, and the atmosphere would eventually be almost barren of gaseous oxygen if photosynthesis stopped.

Commonly used notation for photosynthesis is: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. This indicates that the reactants, six carbon dioxide molecules, and six water molecules, are transformed into a sugar molecule and six oxygen molecules, the products, by light energy being absorbed by chlorophyll (implied by the arrow).

The creature consumes the sugar, and as a byproduct, oxygen is produced.

Therefore, the energy source is light, reactants are carbon dioxide and water, the waste product is oxygen and the primary energy is glucose.

Answers

Answer:

Environmental change

Explanation:

A species that has little genetic variation cannot evolve (change) in response to variable environmental conditions because genetic variation is the raw material on which natural selection operates to select individuals. Adaptation to changing environmental conditions only can occur when there is variation (either genetic or phenotypic variation). In consequence, a species with low genetic variation is at a high risk of extinction, especially in challenging environments.

Marianne is conducting an experiment on homeostasis in paramecium, which is a type of single-felled organism. Which of these observations provides the strongest evidence of a paramecium maintaining homeostasis

Answers

Hello. You did not present the answer options, which makes it difficult for you to receive a specific answer. However, I will try to help you in the best possible way.

One of the most common evidences that a paramecium is maintaining homeostasis is the pumping of water from the vacuoles present in its body.

The paramecium is a protozoan that lives in aquatic environments, mainly those composed of fresh water. The problem with this environment is that water is able to enter the paramecium organism in large quantities and this can promote the disruption of the organism through lysis of the cell. In this case, homeostasis must act quickly and pump water out of the body, through the cell vacuole.

Homeostasis is a regulatory system of the organism, which must promote the balance of the organism, whenever any external or internal factor tries to harm this balance.

Search using the internet on how you can expand or enhance one's knowledge of animal/fish raising.​

Answers

Answer:

Fish farming involves raising a variety of aquatic animals, such as fish, mollusks and shrimps in an enclosure such as a tank or pond. With the surge in demand for healthy animal protein the  demand for fish and fish products is on the rise. Fish farms have the potential to produce fish for home consumption at about $0.90/lb which is a considerable saving when compared to supermarket prices of over $2.00/lb.

The first step for fish farming is to determine what you are going to do with your full-grown fish. You need to know the purpose, whether you are going to keep fish as a pet or for fish meat. This will decide a lot of things like the space requirements, equipment and capital requirements. If you intend to keep fish as a pet for showcase then a small tank or a backyard small fish farm is sufficient. If you intend to put a small fish farm with one or two ponds then also with a little business mindset you can market 1000 to 2000 lb of fish.  

This will also require you to set up a business entity and have a business mindset.The costs associated with raising different types of fish varies because different fish need certain temperature water to live. The type of fish also decides the requirement of equipment and the feed cost. There are lots of laws about raising fish and animals, and even more, stringent laws related to raising animals that are going to be consumed as food.

Before starting fish farms or fish hatchery of any size or type it is advisable to check local laws and the need of permits  to do so in your area.Normally you will get a license to operate your fish farm for a year which will be renewable. You need to submit the following documents to apply for the license:

Filled in application form

Sketch or aerial map of the facility layout, including dimensions

Copy of fish health certificate

Copy of stocking permit

Letter of a written permission from the landowner (in case if you are not the landowner)

The company wishes to determine what its Year 5 income and December 31, Year 5, stockholders' equity would be if it had used U.S. GAAP. Relevant information follows: o QualCore carries property that it uses for its own operations at revalued amounts. This property was last revalued upward by $350,000 on January 1, Year 3. At that time, it had a remaining useful life of 10 years. o QualCore held no investment properties at the start of Year 5. However, on January 1, it purchased an office facility for $1.2 million and immediately began leasing it to tenants. QualCore accounts for this investment property using the fair value method. An appraiser reported that the facility's fair value was $1.4 million on December 31, Year 5. If QualCore had used the cost method for the facility, it would have computed depreciation using a 20- year useful life with no residual value. o QualCore capitalized development costs related to a new product in Year 4 in the amount of $800,000. QualCore began selling the new product in January, Year 5, and expects the product to be marketable for a total of five years. Required: 1.
