Which of the following statements is true regarding anabolism?
Choose 1 answer:
А) Energy is released during anabolic reactions.
B) In anabolism, larger molecules are made from smaller molecules.
C) Anabolism is the sum of all the chemical reactions in a cell.
D) Anabolism uses the process of hydrolysis to join molecules together.
Answer:
B) In anabolism, larger molecules are made from smaller molecules.
Explanation:
Anabolism is a metabolic process that uses up energy that is produced to build up complex and larger molecules from smaller ones. It is part of the chemical process that takes place in a cell.
For example, photosynthesis is an anabolic process, in which the cell forms larger molecules such as glucose from smaller molecules like water and carbon dioxide, with the use of solar energy.
Option B is true regarding anabolism.

Answer:
OA
Explanation:
Chemical energy refers to the energy that is released with reactions involving chemicals. Cellular respiration takes glucose(a five carbon sugar) and breaks it down using glycolysis, then makes ATP(adenisine-triphosphate)(an essential chemical to the energy of life) using the krebs cycle and the electron transport train. This is all to get a surplus ATP, which is a useable CHEMICAL ENERGY source. This energy can be diverted to any system in the body, including the muscular system. Then, the muscles are used MECHANICALLY(look at the types of muscle levers in anatomy) to acheive work, thanks to the CHEMICAL ENERGY produced in cellular respiration. Thus, the answer in OA.

Name the mandibular motion resulting from the following combinations of muscle contractions: ________
a) B Masseter, B Temporalis, B Medial Pterygoid
b) L Lateral Pterygoid, R Masseter
c) B Lateral Pterygoid, B Medial Pterygoid
d) B Lateral Pterygoid, B Digastric
Answer:
c) B Lateral Pterygoid, B Medial Pterygoid
Mandibular motion is by combinations of B Lateral Pterygoid, and B Medial Pterygoid contraction which controls the mandible's closure, hence option c is correct.
What are muscle contractions?There are several of these, including the masseter and temporalis muscles, which control the mandible's closure; the medial pterygoid muscle, which controls the mandible's closure and lateral movements.
The lateral pterygoid muscle, controls the mandible's opening, deviation to either side, and anterior movement.
The lateral pterygoid muscles on the side that is contralateral to the excursion are contracted to move the jaw to one side (laterotrusion), with the help of the posterior temporalis muscle on the same side (ipsilateral).
Therefore the combination of B Lateral Pterygoid, and B Medial Pterygoid creates mandibular motion, hence option c is correct.

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
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.

arrow
Fill in the blank to complete the statement about the
plate boundary
This boundary is between the African Plate and the
Plate
Answer:
Its Eurasian
Explanation:
This boundary is between the African Plate and the Eurasian Plate.
This boundary is known as a convergent plate boundary. Convergent plate boundaries occur when two tectonic plates move toward each other.
In the case of the African Plate and the Eurasian Plate, they are colliding, and one plate is being forced beneath the other in a process called subduction.
As the plates converge, the intense pressure and friction cause seismic activity, leading to earthquakes and volcanic eruptions in the region.
These collisions also result in the formation of mountain ranges, such as the Himalayas, as the crust is pushed upward and folded.
Studying this convergent plate boundary is essential for understanding the geological processes shaping our planet's surface and the associated hazards like earthquakes and volcanoes.

Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation allow for the change of gene pools over time
OPTIONS:
A) biogeographic isolation affects the random changes that take place within gene pools
B) biogeographic isolation affects the changes in gene pools that result from which organisms are breeding
C) biogeographic isolation determines who will win competition for mates
D) biogeographic isolation determines the time that populations will breed
Answer:
A) biogeographic isolation affects the random changes that take place within gene pools
Explanation:
Organisms can become splitted and isolated from each other by biogeographical factors, thereby preventing the isolated population of species from interbreeding with each other. When this occurs, the isolated population, over time, evolve separately and later become distinct from each other leading to a change in the original gene pool.
Biogeographical factors uch as habitat isolation can cause a change in the original gene of a species population which have now become isolated geographically, and thus, evolve separately.

Predict which one of the following organisms will have the highest percentage of unsaturated fatty acid chains in their membranes: Group of answer choices thermophilic bacteria desert iguana humans antarctic fish
Answer:
Humans
Explanation:
Humans are bigger than most beings and some people are extremely obese.
The organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.
Unsaturated fatty acid chains have one or more double bonds, while saturated fatty acid chains do not contain any double bonds.When the temperature decreases, the composition of the phospholipids bilayer membrane becomes more unsaturated to be able to maintain different properties such as homeoviscosity.In consequence, membrane lipids exhibit the highest percentage of unsaturated fatty acid chains during cold acclimation.In conclusion, the organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.

Phosphorus is a critical constituent of cellular fluids because of its role: a.as a sodium ion transporter in body cells b.in the synthesis of amino acids c.in the synthesis of phospholipids to transport fats through the blood d.in binding with calcium in the muscle tissues e.as a buffer in maintaining the optimum body pH
Answer:
e is correct
Explanation :
Phosphorus is critical because this element is required for enzymatic activities that take place during glycolysis, in the metabolism of glutamine to form ammonia (ammoniagenesis) and also in oxidative phosphorylation, where the cells produce energy from the generation of ATP from ADP.
In serum (blood plasma), the inorganic phosphate is combined with oxygen (O2) to form diverse types of phosphates (PO4) molecules that play key functions in muscle activity, nervous system development, and bone growth.
Serum phosphate is a critical buffer that maintains the acid‐base balance in the urine. The serum phosphate level in an adult must be in the range of 2.5 to 4.5 mg/dl, being higher levels indicative of hyperphosphatemia. This inorganic phosphate has important functions during the ATP synthesis, cyclic AMP, post-translational modification (i.e., protein phosphorylation), and also as an intracellular buffer.

1. Summarize the six ways the loss of Arctic ice is affecting everyone.
six ways are temperature,coastal communities,food,shipping,wildlife,permafrost
Answer:
Explanation:
Artic Ice are melting due to change in the climatic system as a result of global warming. The active increase in human activity resulting in global warming will continually perpetuate the decrease in artic Ice.
Artic heat help to balance temperature or heat on the earth surface by reflecting heat back into the environment. When the artic Ice is reduced, the amount of heat reflected is also reduces.
Coastal community - a continuous rise in ocean level can lead to flooding which will affect the coastal community surrounding the ocean. An the ocean has been incredible gradually over the pass decades.
Food - Reduction in the artic Ice car Lea to increase heat affect crop growth through damage by heat stresses leading to an increase price rate of food.
Meltng of Ice increase the shipping routes causing more harm through ship wrek.
Melting of Ice can leave to loss of animals that depends on it for survival.
Permafrost occurs when the ground is permanently block or frozen leading to accumulation of methane gases that causes global warming.
