In some cases, people who test positive for genetic testing can receive preventive treatments. For example people who test positive for the breast cancer genes BRCA1 and BRCA2 can have a preventive mastectomy (breast removal surgery) before they develop the disease. In other cases, no preventive treatments are available, but frequent monitoring can help detect a disease earlier, when it's more easily treated.
What ethical or professional concerns does a health-care professional need to address when he or she has a patient who wants to prematurely treat a genetic disease? Do you think genetic testing should be part of normal preventive healthcare? Why or why not.
Answer:
Yes because genetic testing will provide enough evidice for the genetic disease. If you do so you can find diseases before they have long lasting effects on the hosts body

Determine which of the following statements is true about energy in ecosystems A. Consumers pass on 20% of the energy they get from a lower trophic level. OB. Primary consumers lose 60% of the energy they absorb from producers as urine and feces. C. 10% of the energy Primary consumers absorb is lost as heat. Ons Primary producers lose 20% of the energy they absorb as urine and feces.
Answer: C. 10% of the energy Primary consumers absorb is lost as heat.
Explanation:
According to the ten percent law of energy flow only 10 percent energy is transferred from one trophic level to the next trophic level and rest of the energy is used to develop the biomass and lost as heat. As the loss of heat is an essential exothermic reaction after the digestion and assimilation of food the energy is lost as heat from the body of the primary consumers is 10%. Primary consumers are animals that are dependent on plants for their food requirements for example deer, goat and others.
A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Saritha paid ₹27 for a book kept for seven days, while Susy paid ₹21 for the book she kept for five days. Find the fixed charge and the charge for each extra day.
Answer:
See the attachment.
Hope u understand
In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.
A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.
Let the fixed charge for the first three days be x and the charge for each extra day be y.
From the given information, we can set up two equations:
For Saritha: [tex]\rm 3x + 4y = 27 -----(equation 1)[/tex]
For Susy: [tex]\rm 3x + 2y = 21 -----(equation 2)[/tex]
We can solve for x and y by using elimination or substitution:
Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:
[tex]\rm 3x + 4y = 27[/tex]
[tex]\rm - (6x + 4y = 42)[/tex]
Solving above equations, we get:
[tex]\rm -3x = -15[/tex]
[tex]\rm x = 5[/tex]
Substituting x = 5 into one of the equations, we can solve for y:
[tex]\rm 3(5) + 4y = 27[/tex]
[tex]\rm 15 + 4y = 27[/tex]
[tex]\rm 4y = 12[/tex]
[tex]\rm y = 3[/tex]
Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

What happens if Rainsford refuses to play the game?
A.
he is set free
B.
he must swim to a passing boat
C.
Ivan gets him
D.
he lives with Zaroff forever
Answer:
C. Ivan gets him.
Explanation:
Richard Connell's "The Most Dangerous Game" is about Sanger Rainsford, a famous hunter who cared less about his prey. But then the tables turned and he became hunted instead of being the hunter, thereby presenting the theme of civilization and savagery, conscience, etc.
After Rainsford reached "Ship Trap Island", he discovered that there lived someone, Colonel Zaroff. But soon, he became aware of the "game" that the colonel likes to hunt. Refusing to be a part of the hunt, he was offered to be either the prey (which leaves him a choice of being free if he survives 3 days being hunted) or be killed anyway by Ivan, the Cossack.
Thus, the correct answer is option C.

Why do you think scientists track the genes of other organisms such as rats or mice in the database? Do you think rat genes are important to human gene research?
Scientists study and track other animals' genes in an effort to understand how non-human creatures' genes work and operate. They do this to understand genetic risk factors in illnesses in the human population. This comes primarily from research on the genes of mice because mice are incredibly genetically close to humans --- there are literally thousands of genes in mice and rats that are phenomenally similar to humans. Manipulating their genes is extremely simple, such as adding or deleting genes to better understand their bodily functions --- also known as genetic engineering. The majority of mice and rats used in genetic research and medical studies are inbred and genetically similar, which makes the medical trial outcomes more consistent. This helps us find an understanding in whatever it is that we're trying to find.
Scientists track the genes of other organisms like rats and mice in databases because these organisms share evolutionary similarities with humans, allowing researchers to study biological processes, diseases, and potential treatments that can apply to humans.
Rat genes are important to human gene research due to their similarities and potential for modeling human diseases and drug responses.
Scientists track the genes of various organisms, including rats and mice, in databases because these organisms serve as valuable model systems for studying biological processes, genetics, diseases, and potential treatments that are relevant to humans. Despite the differences in size and appearance, many biological functions and genetic pathways are conserved across species due to evolutionary relationships.
Rats and mice share a significant portion of their genes with humans and have similar anatomical and physiological characteristics. This similarity allows researchers to study fundamental biological mechanisms and disease processes in these animals and extrapolate the findings to humans. By tracking the genes of these organisms in databases, scientists can access a wealth of information about their genetic makeup, which aids in designing experiments and conducting comparative studies.
Rat genes, in particular, are important to human gene research because rats have a similar genomic organization and share many orthologous genes with humans. Rats are used extensively in medical and scientific research as model organisms to study human diseases such as cancer, cardiovascular disorders, diabetes, neurological conditions, and more. Their genetic and physiological similarities enable researchers to mimic disease processes and test potential therapeutic interventions in rats before moving to human clinical trials.
In summary, tracking the genes of organisms like rats and mice in databases is essential for advancing our understanding of genetics, diseases, and treatments that apply to humans. Rat genes are valuable in human gene research due to their evolutionary relationship with humans and their potential for modeling human diseases and drug responses, ultimately contributing to the development of medical treatments and therapies.

while obtaining the vitals during the seconary assessment, the EMT will assess the respirations. what woul dbe included about the respirations during the primary vitals assessment
Answer:
Rate and tidal volume
Explanation:
Tidal volume is the volume of air moved in or out of the lungs with each normal breath. A normal tidal volume is around 500 to 600 mL per inspiration and/or 6 to 7 mL per kilogram of body mass. An Emergency Medical Technician (EMT) should assess the respiratory rate (as well as rhythm and quality), having into account that a normal respiratory rate in an adult is 12 to 18 breaths per minute (BPM). Moreover, an appropriate tidal volume is also fundamental in assisting individuals in respiratory distress and arrest.
Leaf is modified into thorn where water availability is low.....give reason?
Answer:
To help conserve water or prevent loss via transpiration from the leaves
Explanation:
Some plants are found growing in habitats with little or no moisture content as annual rainfall is very low. These plants are called xerophytic plants. However, despite the low water condition, these plants are adapted to the environment and still survive.
One of their adaptation (structural) is that their leaves are reduced to thorns. Ideally, plants tend to lose water via the stomata on the leaves in a process called TRANSPIRATION. Hence, the leaves of plants adapted to a xerophytic habitat is modified to thorns in order to prevent water loss from the leaves and conserve the water.

You are examining the data from two time points taken in an experiment. At time 1 there was an extracellular concentration of Na of 115 mM outside the cell and 8mM inside the cell. An amino acid, lycine, is at 20mM outside and 40mM inside. At the second time measured Na is 100mM outside the cell and 23 mM inside the cell. Lycine is 15 mM outside the cell and 45mM inside. What is the best explanation
Answer:
See the answer below
Explanation:
The best explanation would be that both Na and the amino acid lycine are simultaneously diffusing (in bound form) from the outside to the inside of the cell.
Considering the Na alone, one would see that the concentration outside the cell decreased in equal amount (15 mM) as the increase in the intracellular concentration of the same molecule.
Also considering the amino acid alone, the extracellular concentration increased by the same magnitude (5 mM) as the decrease in the intracellular concentration of the same molecule.
Hence, it could only be that both molecules bind together and diffused from the region of higher concentration (outside of the cell) to the region of lower concentration (inside).

Is the cell an open or closed system? Explain your
answer using at least one example of a cell
organelle and its function
· In an open system matter and energy can be transferred
· In a closed system only energy can be exchanged
· In an isolated system neither matter nor energy can be exchanged
· The cell has to be an open system because it needs to exchange matter and energy and the only way to do so is through an open system
· As an open system the cell allows nutrients to enter the cell and waste products to exit the cell
· The cell does this through the use of a semi-permeable membrane
· It needs nutrients in the forms of glucose, ions and many other molecules.
· The nutrients can come into the cell through either passive or active transport
· In passive transport the nutrients naturally move from a higher concentration gradient to a concentration gradient.
· During active transport the particle need to move against the concentration gradient. To do this the cell needs energy to transport the materials. The energy comes in the form of ATP.

Transfer RNA has __________ bases attached to one end of the molecule and an amino acid to the other.
Answer:
Nitrogenous
Explanation:
Transfer RNA, also known as tRNA, is one of the three types of RNA. It is involved in the translation process. The shape of the tRNA allows it to be a very important component of the translation process.
The morphological structure of the tRNA is in such a way that a sequence of nitrogenous bases called ANTICODON attach to one of its ends while an amino acid is attached to the other end. This way the tRNA molecule is able to read the mRNA codon using its anticodons and carry the corresponding amino acids.
N.B; the anticodons are composed of three nitrogenous bases just like codons. Codons are complementary to anticodons.

does the gut flora affect digestion?
Answer:
Yes.
Explanation:
Our bodies need different organs to regulate our bodily functions, and the gut is no different. The gut flora helps us digest and break down the food we eat, along with producing various enzymes that help to break down carbohydrates. Also, after the carbohydrates are broken down, they can pass through the gut wall into the blood (just a little fun fact). The gut also helps to benefit our immune system. One last bit of information is that an imbalance of bacteria and microbes in our bodies may lead to weight gain, high blood sugar, high cholesterol, and many other terrible issues.

Which of the following adaptations enables deciduous trees to produce more food?
a.
broad leaves
b.
thick bark
c.
leaf loss
d.
color change
The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food. Broad leaves have the benefit of increasing the photosynthetic rate, resulting in more food production.
What is the role of the leaves?Leaves are of many types, such as the neddle-shaped leaf and flat leaves, and all these leaves are adapted to different climatic conditions. The plants that are present in the tropical area have comparatively flat leaves compared to those that are present in the cold areas in order to control transpiration and heat.
Leafy plants that are green in color have chloroplasts and chlorophyll pigments that help in the photosynthesis process. Because the photosynthesis process produces food, if the leaf is green, it has more chloroplasts and thus produces more food.
Hence, The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food.

Which does not provide for enhanced genetic mixing?
A.Mix-matching
B.Random segregation
C.Crossing over
D.Fertilization that occurs through sexual reproduction
Answer:
A. Mix-matching
Explanation:
Sexual reproduction increases genetic variation in offspring by three main mechanisms: 1-random assortment of chromosomes during meiosis 2-genetic recombination, and 3-random fusion of gametes from different parents. In the first place, the pairs of homologous chromosomes are randomly oriented in metaphase I before they separate in Anaphase I. In consequence, daughter gamete cells receive different combinations of chromosomes. Second, recombination (also called crossing over) refers to the interchange of genetic material between non-sister chromatids during prophase I, thereby also increasing genetic variation in daughter cells. Third, the fusion of two haploid cells (i.e., gametes) in diploid organisms results in the formation of a single zygote cell that develops into a new organism, thereby the process of random fertilization between any two gametes generates different diploid zygotes, increasing thus genetic diversity.
Why dont plant cells have microvilli?
Answer: They don’t have microvili because they don’t need it.
Explanation:
Animal cells have this because it increase surface area and helps absorb food and water molecules.
Plant cells do not have microvilli because they do not require the same type of surface area enlargement as animal cells.
Microvilli are small, finger-like projections that extend from the surface of animal cells. They help to increase the surface area of the cell, which is important for functions such as absorption and secretion.
Whereas plant cells have a rigid cell wall that provides structural support and protection. They have evolved unique structures to meet their specific needs, such as chloroplasts for photosynthesis and a cell wall for support and protection.
So, the absence of microvilli in plant cells is not a disadvantage since they do not require the same surface area enlargement as animal cells.
Therefore, the absence of microvilli in plant cells is due to their unique structural and functional needs.
