The polypeptide encoded by the glucose carrier gene has a signal sequence. As a result, the ribosome and the polypeptide that is beginning to be made will be transported to the _________ (a cellular compartment) where translation will continue. Then the newly made glucose carrier protein will travel through ______________ (another cellular compartment), and then finally be sent to the plasma membrane. Once there, it will allow glucose to enter the cell through _________________ (simple diffusion, facilitated diffusion or active transport).
Answer:
The correct words for the three blanks are as follows:
1. Endoplasmic reticulum. 2. Golgi apparatus. 3. Facilitated diffusion.
Explanation:
During the translation stage of protein synthesis, signal sequences are either attached or excluded from a synthesized protein in order to indicate the right location it should be sent to. Proteins that possess signal sequences are usually sent to the endoplasmic reticulum, where they will be folded into their right shapes. From the endoplasmic reticulum the proteins are then transported into Golgi apparatus via membrane vesicles. In the Golgi apparatus, proteins undergo their final modifications before they are transported to their final destinations. The final destination of glucose carrier proteins is the plasma membrane, where they help glucose molecules to enter the cell via facilitated diffusion.

Would the pi values of the animal insulins be the same as, greater than, or less than human insulin?
The pI values for animals and human insulin are the same, with the exception of duck and chicken insulin.
What is a pI value?The pI value is the isoelectric point of the protein or amino acid chain. The isoelectric point can be given as the pH value at which the net charge of the insulin molecule is zero.
The insulin molecule is composed of amino acids that are charged at a specific pH. With the change in the pH, charge transfer takes place and results in the net-zero pH at pI.
The changeable amino acids in animal insulin and human insulin are the same. Thus, the pI values for human and animal insulin are the same.
The exceptions to the condition are duck and chicken insulin.

https://brainly.com/question/6658031
Final answer:
Animal insulins such as bovine and porcine may have different isoelectric points (pI) compared to human insulin due to variations in amino acid sequences. Recombinant DNA technology enables the production of insulin identical to human insulin, which circumvents the immune response issues caused by animal-sourced insulin.
Explanation:
The isoelectric point (pI) of animal insulins such as those derived from pigs (bovine) and cows (porcine) may differ from that of human insulin due to their amino acid composition differences. Pig insulin differs from human insulin by one amino acid and beef insulin by three. These sequence differences can affect the pI of the insulin molecules because pI is determined by the overall charge of the protein, which in turn is influenced by the presence and position of charged amino acids within the sequence.
Insulin's functionality is also related to its similarity to human insulin. Although animal insulins were effective in treating diabetes, they were recognized by the immune system as foreign, which could lead to an antibody response and require higher doses of insulin for treatment. Furthermore, the animal-derived insulin had the potential to induce other immunological complications.
With the advent of recombinant DNA technology, it has become possible to produce insulin that is identical to human insulin in bacteria like E. coli. This insulin has the same sequence and therefore the same pI as naturally occurring human insulin, eliminating the immune response seen with animal-sourced insulins and allowing for a more consistent and safe treatment for diabetes.

Which stage of cellular respiration produces the most atp?
Answer:
Electron transport Chain (Oxidative phosphorylation)
Explanation:
Cellular respiration can be defined as the process that involves the breakdown of glucose molecules into CO2 and H2O to generate energy inform of Adenosine Triphosphate (ATP). Also, cellular respiration usually takes place in the cells of an organism by converting biochemical energy present nutrients into Adenosine Triphosphate. Furthermore, it takes place in three stages which includes: glycolysis, TCA cycle and Electron transport (Oxidative phosphorylation). Thus, oxidative phosphorylation is the final stage of aerobic cellular respiration that produces maximum ATPs.
The oxidative phosphorylation stage of cellular respiration produces the most ATP. This stage utilizes an electron transport system to create an electrochemical gradient, which facilitates the production of ATP. Although other stages also produce ATP, about 90% is made during oxidative phosphorylation.
Explanation:The stage of cellular respiration that produces the most ATP is the Oxidative Phosphorylation stage. During this stage, NADH and FADH2, made in glycolysis, the transition reaction, and the Krebs cycle, transfer their electrons to an electron transport system (ETS). This series of reactions is facilitated by protein complexes located in the inner membrane of a cell's mitochondria. The energy from the transferred electrons then creates an electrochemical gradient across the membrane, leading to the production of ATP through chemiosmosis, also known as oxidative phosphorylation.
It's important to note that while other phases such as glycolysis and the Krebs cycle also produce ATP, the bulk, about 90%, is generated during oxidative phosphorylation. This makes oxidative phosphorylation the most ATP-rich stage of cellular respiration.
For every oxidized NADH in the electron transport chain (ETC), approximately three ATP are produced, and around two ATP are produced for each oxidized FADH2. Consequently, one glucose molecule that enters the aerobic respiration process can net roughly 36 ATP in total.

How many amur leopards are left in the world 2019
Answer:
About 70
Explanation:
Amur leopard is a rare subspecies located at Russian Far East. They are solitary, nocturnal animals that are highly territorial. The number of individuals in the is very low, because Amur leopards are on the brink of extinction. This is because their main threat are humans-hunters who kill them for the fur, but also development of the cities and farm on leopards' habitat. Since their population is small, interbreeding is a huge problem.
As of 2019, there were about 100 Amur leopards left in the world. These critically endangered big cats are primarily found in the Russian Far East and Northeast China, and their survival depends heavily on ongoing conservation efforts.
Explanation:As of 2019, there were approximately 100 Amur leopards left in the world. The Amur leopard is a critically endangered species, and concerted conservation efforts are vital for their survival. The population estimates for these elusive big cats are based on camera trap studies and other types of research that monitor their presence in the wild.
The Amur leopard, also known as the Far Eastern leopard, inhabits the Russian Far East and Northeast China, and its small population size has placed it at extreme risk of extinction due to poaching, habitat loss, and inbreeding. Conservation programs, including anti-poaching measures and habitat preservation, are crucial to increase their numbers and ensure their future.

List the structures that make up the pathway of air through the respiratory system starting with the external nares.
Answer:
Nose: Air is inhaled through the nostrils (and sometimes through the mouth) where it is filtered by the hairs and cilia to remove dust particles and moistened. The nasal cavity also moderates the temperature of the inhaled air.
Pharynx: This is a common passage for food, water, and air. It leads from both the nose and the mouth and leads to both the trachea (windpipe) and the oesophagus (foodpipe).
Larynx: This is the voice box situated just over the trachea and has a flap called the epiglottis which closes during swallowing to prevent food from entering the trachea and opens during breathing.
Trachea: Air now enters the windpipe which is situated behind the sternum (breastbone) and between the two lungs.
Bronchus: From the trachea, two bronchi (one bronchus for each lung) enter the lungs and divide and subdivide into secondary and tertiary bronchi, getting narrower as they proceed into the lung.
Bronchioles: The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air.
Alveoli:. Air ends its pathway in the alveoli (sing. alveolus) which are tiny sacs with very fine singe-celled walls. These alveoli are surrounded by capillaries that connect the pulmonary arteries and veins and that enable transfer of oxygen and carbon dioxide.
The pathway of air through the respiratory system starting with the external nares includes the nose, mouth, larynx, pharynx, lungs, and diaphragm.
Explanation:The pathway of air through the respiratory system starting with the external nares includes the following structures:
Nose: The major entrance and exit for the respiratory system.Mouth: A secondary opening for the respiratory tract.Larynx: Also known as the voice box, it connects the pharynx to the trachea.Pharynx: It is composed of three major sections: the nasopharynx, oropharynx, and laryngopharynx. It connects the nasal cavity and oral cavity to the trachea and esophagus.Lungs: The main organs of the respiratory system where gas exchange takes place.Diaphragm: A dome-shaped muscle that separates the chest and abdominal cavities and plays a role in breathing.

On the Bahamian island of Andros, mosquitofish populations live in various, now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences. Which two of the following have operated to increase divergence between mosquitofish populations on Andros? improved gene flow bottleneck effect sexual selection founder effect natural selection
The increased divergence between mosquitofish populations on Andros is due to the bottleneck effect and natural selection.
Explanation:The two factors that have operated to increase divergence between mosquitofish populations on Andros are the bottleneck effect and natural selection. The bottleneck effect occurs when a population is drastically reduced, resulting in a loss of genetic variation. In this case, the isolation of the ponds from each other created smaller populations that were exposed to different selective pressures, leading to divergence. Natural selection then acts on these smaller populations, favoring traits that are advantageous in their specific pond environment.

Which best explains the importance of nitrogen in the cycling of energy and
matter?
A Nitrogen increases protein production in plants.
B Nitrogen decreases protein production in plants.
C Nitrogen decreases the effectiveness of photosynthesis.
D Nitrogen increases the effectiveness of photosynthesis.
Answer:
The correct option is A.
Explanation:
Nitrogen is a gas that is present in high quantity in the atmosphere. This gas contribute significantly to the growth and development of plants and that of animals. Nitrogen in the atmosphere usually get incorporated into the soil via lightening and it is typically fixed by nitrogen fixing bacteria. This nitrogen is then used as part of the nutrients that plants need to grow and develop and it is also used in the production of protein in plant parts. Animals use these plants as source of proteins in their diets. Ultimately the waste products derived from protein is return to the soil where they are broken down by decomposers to nitrogen forms that plants can use. Thus, nitrogen increases the production of proteins in plants.
Option A) Nitrogen increases protein production in plants, vital for growth and development, making it crucial in the cycling of energy.
The best explanation for the importance of nitrogen in the cycling of energy and matter is that nitrogen increases protein production in plants (Option A). Nitrogen is a critical macronutrient, essential for the synthesis of proteins, nucleic acids, and chlorophyll. Plants require these compounds for growth and development, and insufficient nitrogen can lead to stunted growth and chlorosis (yellowing of leaves). Atmospheric nitrogen (N₂) is abundant but not directly usable by plants; they rely on nitrogen fixation processes to convert it into biologically available forms like ammonia (NH3). Nitrogen is thus crucial for the primary productivity of plants and the overall health of ecosystems.
All else being equal, selection should more strongly favor reinforcement of reproductive isolation among related species in:peripatric populations over sympatric populations.peripatric populations over allopatric populations.allopatric populations over peripatric populations.allopatric populations over sympatric populations.sympatric populations over allopatric populations.
Answer:
sympatric populations over allopatric populations.
Explanation:
Allopatric speciation is a form of speciation (creation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations reach a high level of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
New populations evolve as result of mutation, genetic drift and natural selection.
Sympatric speciation is a form of speciation without geographic isolation, usually due to the reproductive isolation or changes in the chromosomes of the organism.

Final answer:
To ascertain if Barbara has lung problems, several vital signs including heart rate, breathing rate, blood oxygen level, and lung sounds are considered. Evidence of hypoxemia, crackling sounds, and abnormal chest radiograph indicators such as shadows or cavitation suggest lung issues like pneumonia.
Explanation:
Indicators of Lung Problems
To determine if Barbara is having a problem with her lungs, a healthcare professional would look at vital signs such as her heart rate, breathing rate, and blood pressure. Additionally, they would assess her blood oxygen level using a pulse oximeter, and listen for abnormal sounds in the lungs through auscultation. With Barbara presenting a slightly elevated heart rate, hypoxemia, and crackling sounds in her lungs during breathing, these observations point toward potential lung issues. The greenish sputum sample and shadow on the chest radiograph further suggest a lung infection, possibly pneumonia.
The presence of crepitation during auscultation can indicate increased resistance in the lungs, which might be a result of an obstruction or infection, causing difficulty in air passage and gas exchange. This scenario could manifest through a patient showing signs such as shortness of breath, a productive cough, and abnormal pulse oximeter readings, as in the cases described for Sacheen and Benjamin, where clogged airways or infection impact blood oxygen levels.
