When you examine fluid that you have drawn from a blood vessel in someone's arm, you find that it is relatively high in carbon dioxide and waste products. Assuming that the fluid comes from a healthy individual, you conclude that the blood vessel from which you have drawn blood could have been ______.

Answers

Answer 1

Answer:

The given blank can be filled with a venule.

Explanation:

A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.  

The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.

A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible. Cost is the only consideration in selecting a model organism, since all living things are made of cells anything found will apply to humans. The best choice will must be the very closely related to humans, such as chimps, since anything found in other species will not apply to humans. The most important consideration in selecting a model organism is how the public will feel about doing experiments on that species, so the best choice would generally be a very simple organism like bacteria that people don't care very much about.

Answer:

A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible.

Explanation:

The attributes that should be looked for in the selection of good model organism for investigating the impact of toxins in humans include:

Easy maintenance: The easier the maintenance of the organism, the better for both the research and the researcher. More can be achieved with less effort as opposed to high maintenance animals.Fast generation time: They should be able to grow and reproduce quickly so as not to prolong the experiment for too long. The lower the regeneration time, the shorter the time required to obtain adequate data for the research.Genetical similarity to humans: A good model organism for humans related study must share some similarities with humans at the genetic level. The more the genetic similarity, the more applicable the outcome of the research on humans.

Hence, a good model organism should be able to be easily maintained in the laboratory, be fast-growing with a fast generation time, and be as closely related to humans as possible.

When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? Two diverged populations are capable of mating and producing viable and fertile offspring. Hybrid individuals may have reduced fitness and thus be strongly selected against. Hybrid individuals are always allopolyploid and are thus unable to mate with either of the original species. One species has a selective advantage, so as hybridization continues, the other species will go extinct.

Answers

Answer:

Two diverged populations are capable of mating and producing viable and fertile offspring.

Explanation:

Although the biological concept of species says that two different species can not mate and produce viable fertile descendants, the hybrid zones are characterized for being an area where two different genetically groups meet and reproduce. These groups might be the same or different species.

This is a frequent phenomenon in nature, and widely common geographically and among taxonomic groups. It is not rear that different sympatric populations, with a short time of divergence and similar reproductive strategies, can hybridize and even generate new populations that get reproductively isolated from their parentals.

When talking about sympatry we refer to two similar species that coincide in part or their whole distribution area.  

These new populations are even morphologically different from the parental forms, which allow them to colonize new habitats and niches, promoting diversification.

Hibridation zones are very important to conserve, just because they are points of genetic diversity generation and diversification areas.

When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals can form. This is possible because hybrid individuals are always allopolyploid and therefore are unable to mate with any of the original species, to understand more we need to know that......

Hybrid animals

Hybridization, that is, the process through which different species reproduce, generating an offspring, is not considered a very common phenomenon in nature. This is because, in general, species have a distinct number of chromosomes, the cell structures that contain genes. These differences in the number of chromosomes can make the development of the embryo unfeasible, as the alignment of equivalent chromosomes from the female and the male are necessary for the division of the fertilized cell to occur. When this alignment does not occur, the cell does not reproduce and dies. However, in some cases, even with the lack of chromosome pairs, reproduction between different species is successful, generating the hybrid. However, the birth of the individual does not mean that its survival is guaranteed. Often, the hybrid generated is weaker than its parents and does not survive; in other cases, the hybrid can adapt better to the environment than the species that conceived it.

With this information, we can conclude that hybrid animals are a cross between two different species, but this hybrid can have several complications for its survival.

Find the weight of a pine tree that has a circumference of 14 inches and a height of 120 feet. Use the equation: W = b0 + b1(D2H)

Answers

Answer:

The answer is below

Explanation:

The weight of trees is calculated using the equation:

[tex]W=b_o+b_1(D^2H)[/tex]

W is the tree weight in tons, D is the diameter of the tree in inches, H is the height of the tree in feet and [tex]b_o \ and\ b_1[/tex] are constants.

The circumference is given by:

Circumference = 2πr

Where r is the radius and 2r is the diameter

Therefore:

14 = 2(22/7)× r

14 = (22/7)×2r

2r= 14 × 7 / 22

Diameter = 2r = 4.455 inches

[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381.643b_1\\Let\ us\ assume\ b_o = -35,b_1=1.9.\\Therefore\\W = -35+2381.643(1.9)\\W=4490 \ tons[/tex]

Exceptions to the Central Dogma of Molecular Biology"" What is biggest revolution? Violation of Central dogma--- How &Why?

Answers

Answer:

reverse transcription  

Explanation:

The central dogma of molecular biology states that the flow of the genetic information is unidirectional: DNA to RNA to protein. Thus, the central dogma indicates that a gene is always transcribed into a messenger RNA (mRNA) molecule, and then this mRNA is used as a template for protein synthesis during translation. Reverse transcription is an event that contradicts the central dogma since in this case there are enzymes known as reverse transcriptases that are capable of synthesizing DNA by using RNA as template. In eukaryotic cells, reverse transcription may occur naturally during the insertion of certain Transposable Elements (retrotransposons).

What characteristic of sexual reproduction did Mendel investigate that resulted in offspring expressing characteristics that differed from their parents?

Answers

Explanation:

Mendel crossed two unlike parents to get offspring with characterestics that differ that of the parents

Mendel used the characteristic of sexual reproduction in which the genes from the two parents combine to form the offspring. This results in offspring expressing the characteristics that differed from their parents.

What is Sexual reproduction?

Sexual reproduction is a type of reproduction in which the production of new organisms occur by the combination of genetic information of the two parents or individuals of different sexes. In most of the species, the genetic information is carried on the chromosomes in the nucleus of reproductive cells called gametes, which fuse to form a diploid zygote in the organism which matures to form a complete organism.

Mendel called the material which is responsible for the characteristics as "factors", and he proposed that during sexual reproduction, each of the parent contributed a form of this factor to the resulting offspring. This combination of the parental factors then determined which form of a trait will be visible in the offspring.

After school, Kai feels hungry and tired. He finds some sugar cookies in the cabinet and finishes the whole package.
Which statements best describe the role of glucagon and insulin in this scenario?

was secreted after he ate the cookies because his blood glucose was high.
O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. Glucagon
was secreted after he ate the cookies because his blood glucose was high.
O Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he
ate, insulin from the cookies increased his blood sugar levels.
O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he ate,
glucagon from the cookies increased his blood sugar levels.

Answers

Answer: Option A) Glucagon was secreted by his pancreas before he ate the cookies because blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.

Explanation:When Kai was hungry and his blood glucose level was decreasing, glucagon is the hormone which was secreted by the islets of pancreas to increase the blood sugar levels in his body. Glucagon forces the liver to release the stored glucose in it, which increases the blood glucose level in the body. When Kai ate the sugar cookies there was enough of blood glucose available for his body, also it exceeded the requirement and went high. Insulin was then secreted to control this excess glucose from the islets of pancreas. As it helps the body cells to absorb the glucose and lowers the amount of glucose in the blood. It makes the cell available with the glucose to produce energy and perform their activities.

In short, glucagon and insulin both are secreted by the same organ which is islets of pancreas. But they differ in their function, glucagon increases the blood glucose when the body needs it, whereas insulin helps to absorb the excessive glucose and stores that in the body. Both are the hormones which help in regulating the body glucose levels.

During  process of digestion which takes place in digestive tract statement which describes role of glucagon and insulin is glucagon was secreted by  pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate cookies because his blood glucose was high.

what is the difference between your town's minimum temperatures yesterday? In your answer, list one explanation for why temperature changes during the day.

Answers

Answer:

Maximum temperature was 40 Celsius at daytime while temperature at night was 31 Celsius.

Explanation:

Yesterday maximum temperature was 40 Celsius at daytime while temperature at night was 31 Celsius because during daytime the intensity of sunlight increases the temperature of the particles present in the atmosphere.  So at daytime, temperature increases while at night decrease occurs in the temperature. There is a lot of fluctuation in temperature at daytime due to increasing and lowering the intensity of light.

Answer:

The difference between the high and low temperatures in New York City was 12 degrees. One reason for the temperature difference is Earth’s rotation. Temperatures are generally warmer during the day because that side of the planet is heated by the Sun. At night, that side faces away from the Sun. So, temperatures will be cooler.

3: A device that uses radioactive fluid to determine the active areas of the brain

Explanation:

A positron emission tomography (PET) scan is an imaging test that helps reveal how your tissues and organs are functioning. A PET scan uses a radioactive drug (tracer) to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests.

Depending on the type of exam, the radiotracer is injected, swallowed or inhaled as a gas. It eventually accumulates in the area of the body under examination. A special camera or imaging device detects radioactive emissions from the radiotracer. The camera or device produces pictures and provides molecular information.
