1. Compare gaseous biogeochemical cycle and sedimentary biogeochemical cycle.
Answer:
Gaseous cycles include those of nitrogen, oxygen, carbon, and water; sedimentary cycles include those of iron, calcium, phosphorus, and other more earthbound elements. In a sedimentary cycle elements move from land to water to sediment. Main reservoirs are the soil and sedimentary rocks.
A pair of butterflies reproduces and has one thousand offspring. All one thousand of the offspring have the alleles Aa. What is the most likely combination of alleles (genotype) for each parent? Explain your answer.
Answer:
It is expected that each parent is homo-zygous for each trait (i.e., one parent has genotype AA and the other parent has genotype aa)
Explanation:
An F1 hybrid is the first filial generation of the progeny of distinctly different parental types. In this case, it is expected that each parent is homo-zygous for each trait, thereby 100% of all offspring will have genotype Aa (i.e., parental cross: AA x aa >> F1 = 100% Aa). On the other hand, in a cross where one parent is heterozygous for the trait (Aa) and the other parent is homo-zygous (either AA or aa), only 50% of all offspring will have genotype Aa.
How is the three-dimensional structure of type two collagen fibrils well-suited to their function during bone growth and development?
Answer:
Collagen is a hard, insoluble, and fibrous protein that makes up one-third of the protein in the human body. In most collagens, the molecules are packed together to form long, thin fibrils. These act as supporting structures and anchor cells to each other. They give the skin strength and elasticity.

Which of the following functions at the same organizational level as the kidney in the human excretory system?
A. skeleton
B. epithelial tissue
C. urinary bladder
D. a squamous cell
Answer:
urinary bladder
Explanation:
In biology, there are five levels of organization namely: cell, tissue, organ, system, and organism. A collection of one forms the other, starting from the smallest CELLS. The human excretory system consists of organs that make it up.
Kidney is one of the organs that make up the excretory system. According to this question, the urinary bladder is also an ORGAN, which means that the kidney and bladder as ORGANS are functioning at the same level of organization in the excretory system.
Which statement best explains how sewage systems help fight the spread of disease?A.They carry antibiotics that kill pathogens in the air.B.They add chlorine to drinking water before it is transported to homes.C.They kill the animals that spread pathogenic bacteria.D.They carry human waste to treatment facilities away from cities.
Answer:
D.They carry human waste to treatment facilities away from cities.
Explanation:
Sewage system is a collection of systems that carries sewage (human waste) from the point it was produced to a place where it'll be treated or recycled.
Since sewage is moved via the use of sewage system, it helps to fight the spread of disease by carrying human waste (sewage) to treatment facilities away from cities.

CLAY PARTICLES DO NOT SETTLE DOWN EASILY DURING THE PROCESS OF SEDIMENTATION. CAN YOU SUGGEST ONE METHOD TO MAKE THEM HEAVIER AND THUS HELP IN SEDIMENTATION? Name the method and the chemical
Answer:
Coagulation by additionmof chemicals such as aluminium sulfate also known as alum will help in sedimentation of clay particles.
Explanation:
Clay particles are very small particles found suspended water obtained from streams and rivers for township supply. They have weak electrical negative charges on their surfaces which when they approach one another, they repel each other thus making it almost impossible for clay particles to settle out of suspension.
Because of this, prior to the sedimentation step, a chemical process known as coagulation is required. In this process, certain chemicals called coagulants, are added to the water to bring the difficult-to-settle suspended particles such as clay particles together into larger, heavier masses of solids called flocs. They do these by interfering with the repulsive forces between the particles, thus allowing them to clump together into flocs. The most commonly used coagulant used for water purification is aluminium sulfate or alum. Other chemicals that are also employed in coagulation include ferric sulfate and sodium aluminate.

Which is an endocrine function?
Answer:
Explanation:
The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. The study of the endocrine system and its disorders is known as endocrinology.
where does reabsorbtion of glucose take place?
glomerulus
bowman's capsule
2nd coiled tubule
1st coiled tubule
Answer:
proximal tubule
Explanation:
Glucose reabsorption takes place in the proximal tubule of the nephron, a tube leading out of Bowman's capsule. The cells that line the proximal tubule recapture valuable molecules, including glucose.Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule.

Metabolic rate is _____. See Concept 40.4 (Page) View Available Hint(s) Metabolic rate is _____. See Concept 40.4 (Page) determined when the organism is vigorously exercising after consuming a fatty meal the total amount of energy an animal uses in a unit of time typically higher in an ectothermic animal than in an endothermic one the amount of heat gained by an animal in a unit of time directly proportional to body size
Answer:
The correct answer is ''the total amount of energy an animal uses in a unit of time''
Explanation:
The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.

Cierto.
Explicación:
Todas las células no tenían pared celular. Sabemos que la célula animal es un tipo de célula que solo tiene membrana celular. Las células procariotas se originaron hace aproximadamente 3,5 mil millones de años. Los centríolos son orgánulos cilíndricos, formados por proteínas, que contribuyen en la división celular. El ADN determina las características de un organismo porque el ADN tiene toda la información sobre los organismos. La digestión celular no ocurrió en las mitocondrias. El lugar de la digestión celular son los lisosomas. En la definición de celda, la palabra estructural, se refiere a la composición y forma de la celda. La palabra eucariota significa "núcleo verdadero" y núcleo verdadero significa que la membrana rodea al núcleo.

Select three examples of resistance to antibiotics that is due to an altered cellular target of the drug. Multiple select question. The activity of beta-lactamase Addition of acetyl-CoA to chloramphenicol Alteration of an enzyme involved in folic acid synthesis A change in the structure of 23S rRNA The terminal D-alanine of pentapeptide mutates to D-serine
Answer:
- Alteration of an enzyme involved in folic acid synthesis
- A change in the structure of 23S rRNA
- The terminal D-alanine of pentapeptide mutates to D-serine
Explanation:
Antibiotic resistance is the phenomenon by which microorganisms naturally have, acquire, or develop the ability to defeat the drugs designed to eliminate them. For example, trimethoprim is able to bind with the enzyme dihydrofolate reductase (DHFR) in order to inhibit the folic acid synthesis pathway. Sulfonamides (sulfa drugs) competitively inhibit the incorporation of para-aminobenzoic acid (PABA) into folic acid and thus also prevent the synthesis of folic acid. Ribosomes are organelles where proteins are synthesized. The 23S rRNA is a component of the large subunit (50S) of bacteria and archaea ribosomes. In consequence, it is expected that a modification in the structure of 23S rRNA alters protein synthesis. Finally, vancomycin acts by binding the terminal D-Ala-D-Ala residues of the polymeric lipid-PP-disaccharide-pentapeptides and thus inhibits cell wall synthesis in Gram-positive bacteria. In consequence, it is expected that a mutation at the terminal D-alanine that modifies this sequence alters the vancomycin binding site and thus also confers antibiotic resistance.

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.
=============================================
For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.
Recall that
distance = rate*time
we can rearrange things to say
rate = distance/time
So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.
----------
So,
rate = distance/time
rate = (260 meters)/(180 seconds)
rate = (260/180) meters per second
rate = 1.44 meters per second, which is approximate
I'm rounding to 3 sig figs.
