Congenital hyperinsulinism is a rare condition in which infants experience frequent episodes of hypoglycemia. Based on the functions of the two main hormones that control blood sugar homeostasis, which of the following would be effective at treating the hyperinsulinemia?
A. Glucagon
B. Glucocorticoids
C. Preventing insulin release or production
D. All of the choices are correct.

Answers

Answer 1

Answer:

Any  treatment which involves reduction in the levels of insulin to curb excessive influx of glucose into the cells from the blood  will be an ideal treatments.

Glucagon, which converts excess glucose to glycogen. Glucocorticoids induces insulin resistance thus raises glucose levels.

suppressing insulin release will be another option.

Therefore all options are correct.

Drag the tiles to the boxes to form correct pairs match the type of water with the location in which it is found

Answers

The correct answers are water vapor- atmosphere; surface water -river; ice- glacier; and groundwater -well

Explanation:

Water is an abundant substance on Earth that exists in all states in it. This includes liquid water, which can be found on the Earth surface in water bodies such as rivers, oceans, lakes, ponds, etc. This implies the word that matches surface water is rivers. Additionally, this type of water is usually the ecosystem for many organisms. Besides this, liquid water can be found under the surface, which is known as groundwater, this is located under rocks and soil, despite this, it can be extracted and used for consumption, and one way to do this is through wells. Thus, the word that matches groundwater is well.

On the other hand, water can be found in a gaseous state as this evaporates from the surface of Earth, then raises to the atmosphere, and forms clouds. Thus, the main source of water vapor is the atmosphere. Also, this changes its states as it condensates and falls in the form of rain. Finally, water can be found in solid-state in ice, which is abundant in glaciers, the poles of the Earth, and at high elevations, because ice is the result of water being exposed to low temperatures. Thus, the word that matches ice is glacier.

Answer:

Ice: glacier

Groundwater: A Well

Water Vapor: Atmosphere

Surface Water: The river

Which is a factor that determines whether a molecule can cross a cell membrane?

Answers

Answer:

 if a molecule is too large it cannot pass. also it depends on the concentration of a specific substance inside the cell. similarly, if a molecule is polar it cannot penetrate the phospholipid bilayer. 

there are proteins that work as channels and pumps that allow these molecules to pass

Explanation:

The polarity of the molecule determines whether a molecule can cross a cell membrane. The correct option is D.

What is polarity?

The asymmetric establishment of several cellular components, such as the plasma membrane, cytoskeleton, or organelles, is alluded to as cell polarity.

The polarity of the molecule determines whether a molecule can cross a cell membrane as the cell membrane is composed of phospholipids which are polar in nature.

Assume that plant weight is determined by a pair of alleles at each of two independently assorting loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 4 g to weight and that each allele represented by a lowercase letter contributes 1 g to weight. If a plant with genotype AA BB is crossed with a plant with genotype aa bb, what weights are expected in the F_a progeny?
A. 1 g
B. 4 g
C. 8 g
D. 10 g

Answers

Answer: choice D. 10g

Explanation:

The cross is AABB x aabb so the F1 progeny would have AaBb genotype.

The question states that dominant alleles(uppercase letters) contribute 4g and recessive ones contribute 1g to the weight of the plant.

so for AaBb we would have 4+1+4+1=10g.

A variety of factors influence enzyme activity. Substances that bind to the enzyme and interfere with substrate binding or catalysis are inhibitors. Identify the type of inhibition associated with each of the descriptions and examples by classifying each statement as irreversible, competitive, or mixed inhibition.

Answers

Answer:

Explanation:

Irreversible inhibitors are inhibitors whose action are not reversible. They function by modifying enzyme in a covalent way leading to the formation of new functional group.

Irreversible inhibitors are specific to certain enzymes. Examples is inhibitor that are suicidal they makes inhibitor reactive.

Competitive inhibition are Inhibitor that are competitive in nature they resemble one of the substrate of the enzyme and are been bind to by mistake. Example is an inhibitor that resemble folate an enzyme substrate. Enzyme therefore binds to the inhibitor assuming its folate because they are identical.

Describe the typical principles used to identify topogenic sequences within proteins and how these principles can be used to develop computer algorithms. How does the identification of topogenic sequences lead to prediction of the membrane arrangement of a multipass protein

Answers

Answer:

Topogenic sequences share a series of structural features, and thereby computational algorithms can be used to predict these protein-membrane segments  

Explanation:

Topogenic sequences are protein segments formed by alpha-helical transmembrane domains, which are required for the insertion of membrane proteins. These domains share a series of well-defined features: they are composed of segments of about 20 hydrophobic amino-acid residues. In consequence, computational algorithms can be designed to identify protein patterns that fulfill these structural requirements (i.e. segments with a length of 20 residues, hydrophobic level, etc). The models assign a similarity threshold (threshold value) that predict if the similarity level of the protein pattern is good enough to detect a topogenic segment.

Answers

Answer:

the structure: microfilaments or actin filamentsthe main type of cell: eukaryotic

Explanation:

In eukaryotic cells, the cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a polymer of proteinic subunits united by weak, not covalent connections.

The microfilaments are the thinnest of the three structures. They have a diameter of 7 nanometers and are composed of many proteinic monomers united. This monomeric protein is called actin. Many monomers get combined to form a structure that assembles a double helix.

Due to the fact that these microfilaments are made of actin monomers, they are also known as actin filaments.

Actin filaments have directionality which means that their extremes have different structures.  

Microfilaments interact with myosin filaments. These are associated with transmembrane proteins that have one domain in the cytosol and another in the cell exterior, therefore they participate in the processes of cell mobility.

______ is the process responsible for the situation above. This process can cause DNA to change in many ways. Three such ways are ______, _____, and _____.

Answers

Answer:

Explanation:

Mutation can cause a change in DNA to change in many ways.

Mutation is the sudden change in the genome of an organism that can be heritable from parent by their offspring.

Missense mutation - This occur when a base pair is substituted for by another leading to the formation of an entirely new amino acid.

Nonsense mutation - This occurs when a base pair is substituted for by another leading to the formation of a new amino acid. The new amino acid form therefore send a stop signal to the sequence of amino acid been built.

Insertion or deletion - Insertion mutation inserts new base pair into the sequence changing the number of the DNA base while deletion deletes a base pair changing the number of DNA base from the amino acid sequence.

Does specific heat also mean the amount of energy needed for cooling, or is it only energy for heating?

Answers

Answer:

yes it does

here is a more clearer explanation

Explanation:

The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

Some other examples of specific heat capacities are:

Material Specific heat capacity (J/kg/°C)

Brick 840

Copper 385

Lead 129

Lead will warm up and cool down fastest because it doesn’t take much energy to change its temperature. Brick will take much longer to heat up and cool down. This is why bricks are sometimes used in storage heaters as they stay warm for a long time. Most heaters are filled with oil (1,800 J/kg°C) or water (4,200 J/kg°C) as these emit a lot of energy as they cool down and, therefore, stay warm for a long time.

The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C).

Yes it also means the amount of energy needed for cooling

Which of these statements are accurate? Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. The conformational shift that occurs when glucose, but not water, enters the active site prevents water from hydrolyzing ATP. Hexokinase consists of two domains, or lobes, that come together when glucose and the MgATP2–MgATP2– complex are bound. Most kinases require the presence of a monovalent metal ion cofactor to prevent ATP hydrolysis. Hexokinase is found in the mitochondrial membrane.

Answers

Answer:

A. The conformational shift that occurs when glucose, but not water, enters the active site prevents water from hydrolyzing ATP. True

B. Hexokinase consists of two domains, or lobes, that come together when glucose and the MgATP2–MgATP2– complex are bound. True  

C. Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. True

Explanation:

A. Hexokinase suffers and conformational changes by binding glucose in a reaction that prevents ATP hydrolysis.

B. Hexokinase is an enzyme with two domains that function by binding to the substrate (i.e., glucose). The region linking both protein domains is responsible for the catalytic activity.

C. Hexokinase is a type of transferase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. During the first stage of glycolysis, the hexokinase transfers one phosphorous group from magnesium-ATP (Mg-ATP) to one hexose molecule, such as fructose, mannose or glucose.

 

False statements:

- Most kinases require the presence of a monovalent metal ion cofactor to prevent ATP hydrolysis. False: In canonical kinases, conserved amino acids bind to divalent metal ions before the transference of the phosphate group to their substrates.

- Hexokinase is found in the mitochondrial membrane. False: Hexokinase is found in the cytosol.
