1. What atoms have you learned about that are involved in biomolecules? 2. How is a monomer different from a polymer?
Answer:
Most biomolecules are organic compounds, and just four elements—oxygen, carbon, hydrogen, and nitrogen—make up 96% of the human body's mass. But many other elements, such as the various biometals, are present in small amounts. Sometimes polymers are also known as macromolecules or large-sized molecules. Usually, polymers are organic (but not necessarily). A monomer is a molecule that is able to bond in long chains.

A "U-shaped" distribution for a trait, with high frequencies of individuals who exhibit extreme values for a trait (and few individuals with medium values), is most likely to be caused by ______ selection
Answer:
Disruptive Selection.
Explanation:
Disruptive selection, also known as selection diversification, explains shifts in population genetics that prefer extreme values for a trait over intermediate values. In this case, trait variation increases, and the population is split into two different classes. So, in the given case where A "U-shaped" distribution for a trait, with high frequencies of individuals who exhibit extreme values for a trait (and few individuals with medium values), is most likely to be caused by Disruptive selection.

Explain why the surface of water in a container is not flat but curved?
Answer:
it is due to high surface tension of water
Explanation:
However, for small amounts of water (like in water droplets), surface tension forces become dominant, making the water surface assume a curved, rather than flat shape. In free fall conditions (like in a spacecraft) surface tension causes even larger amounts of water to assume a spherical shape.
When the molecules of the liquid are drawn to the molecules of the container, a concave meniscus forms, which is what you generally witness. A glass tube and water cause this to happen. When molecules, like those of mercury and glass, are more attracted to one another than to the container, a convex meniscus is created.
Why is the surface of water curved?
The nature of the glass and water molecules themselves is to blame, I suppose. Polar molecules, which have positively and negatively charged ends, make up water. Due to the law of attraction between opposites, positive and negative sides of molecules are drawn to one another.

1. Write a hypothesis describing what you believe
may be causing the heavy growth of algae in the
pond. Base your hypothesis on your observations
of the two ponds.
Answer:
The hypothesis is ''the higher population of algae in a pond has a direct relation on the higher concentration of nutrients in the pond''
Explanation:
''The higher population of algae in a pond has a direct relation on the higher concentration of nutrients in the pond''. The population of algae increases vigorously when there is high concentration of nutrients such as nitrogen and phosphorus in the pond. So if there are two ponds having different concentration of nutrients so the population of algae will be higher in that pond where nutrients are present in high amount.
My hypothesis about the heavy growth of algae in the pond is "The growth of algae in the pond is caused by fertilizers and urban runoff entering the pond"
A hypothesis is a plausible explanation of some question of the real world that can be tested (either confirmed or rejected) by using the scientific method.The scientific method is a process that involves making experiments and/or observations to compile data capable of supporting the working hypothesis.In this case, it is possible to test my working hypothesis by measuring the concentration of nutrients (i.e., compounds rich in nitrogenous and phosphorous) associated with fertilizers and urban runoff in the pond that underwent a significant growth of algae and then statistically compare the nutrient level with those observed in ponds free of fertilizers and urban runoff.
In conclusion, a plausible explanation (i.e., a hypothesis) about the heavy growth of algae in the pond may be "The growth of algae in the pond is caused by fertilizers and urban runoff entering the pond"

Explanation:
When the blood ca+ concentration falls below the standard of 4.4-4.5mg/dL,that is below 4.4mg/dL the clinical condition is called hypocalcemia. It is caused by hypothyroidism,due to malfunction of the parathyroid gland.
Generally, Ca+ is needed for contraction of muscles by causing the fusion of the vesicles containing neurotransmitters to the presynaptic membrane for the passage of neuro transmitters to fuse with the receptors on the sarcolemma to initiate muscular contractions by opening of ligand gated Na+. It also interact with the ligand gated sodium ion channels
Generally,Ca+ inhibits depolarization of ligand gated Na+ channels. Thus blocks the opening of these channels and therefore the rate of excitability.Therefore, If the is low serum levels of Ca+,There is increased in the threshold of depolarization because more ligand gated Na+ channels are opened,Thus their is increased excitability of nerves and muscles fibres therefore in the clinical manifestations listed above.
It can be treated with infusion of Ca+ into the blood.

The synthesis of calcitriol, a steroid hormone secreted by the kidney, is dependent on the availability of a related steroid called cholecalciferol (vitamin D3), which may be synthesized in the skin or absorbed from the diet.
a. True
b. False
Answer:
True.
Explanation:
Vitamin D is a fat soluble vitamin that is responsible for fostering the absorption of calcium, magnesium and phosphate in the body.
The synthesis of calciferol is dependent on the availability of a related steroid called cholecalciferol (vitamin D3), which may be synthesized in the skin or absorbed from the diet because keratinocytes of the epidermis and fibroblasts of the skin is response for producing vitamin D3(calciferol) by absorbing it from ultraviolet light when during exposure to UV B photons which protolyses provitamin D3 to pre vitamin D3 in the human body.
It can also be gotten from food sources like milk, cheese, cereals, liver,meat e.t.c.

Answer:
Liver-lung migration
Explanation:
Ascaris lumbricoides is also known as round worm and humans get transmitted through contaminated food and water.
When they are ingested, the hatched larvae then penetrate into the intestinal mucosa and are carried to the liver through the portal venules and are then moved to the lungs . When they are in the lungs they rupture which results in them being coughed up and swallowed. After which they mature, mate and deposit eggs which are excreted and the cycle goes on when humans ingest food contaminated with the eggs.
They cause abdominal pain, nausea and anemia and are treated through drugs such as mebendazole.

these organisms obtain energy through chemosynthesis rather than photosynthesis
Answer:
Autotrophs
Explanation:
Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis. Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen.
The organisms obtain energy through chemosynthesis rather than photosynthesis are called as autotrophs.
What are autotrophs ?The autotrophs are the organisms that produce their own food material by self by using energy from sunlight or a chemical source to drive the process. Plant are the most familiar autotrophs, but there are many autotrophs are present.
An autotroph is an organism that can produce its own food material by using carbon dioxide, light, water or other chemicals. They are also called as producers.
Autotrophs that perform chemosynthesis that they do not use energy coming from the sun to produce food. Instead of this they make food by using energy from chemical reactions.

is there only one way to conduct a scientific experiment why or why not
Answer:
there is more than one mode to conduct an experiment in order to obtain the same results
Explanation:
The scientific method is a methodology used to minimize the bias in the experimentation procedure in order to test a given hypothesis. The scientific method has several steps:1- to raise a hypothesis, 2-to design the experiment, 3- to perform the experiment, 4-to collect data and 5-to analyze results (conclusions). The main aim of the experiment is to obtain data that can be used to confirm (or reject) the hypothesis, which must be testable and falsifiable to be valid. In consequence, the scientific method can be cataloged as an iterative method because different experiments can lead to the same results.
A scientific experiment can be conducted in different ways, with the aim of trying to check the theories and hypotheses, to observe the results of the same.
An experiment is defined as that process by which one or more independent variables are intentionally manipulated to verify or correct the postulates of the hypotheses that have been created. Its goal is to accumulate reliable information.
Scientific experimentation collects the different methods / ways used by researchers to test their theories and assumptions regarding their objects of study, through the repetition of certain phenomena observed in nature, in the controlled environment of the laboratory.
For a scientific experiment to be valid, however, it must comply with the steps of what is contemplated in the scientific method: a series of logical connections and steps to follow to study a phenomenon objectively and verifiably.
Therefore, we can conclude that there are more than one way to conduct a scientific experiment for the verification of the hypothetical knowledge of the researchers following the steps in the scientific method.

A healthy, balanced ecosystem has _______. a. fewer producers than consumers b. more quaternary consumers than primary consumers c. more producers than consumers d. fewer primary consumers than tertiary consumers Please select the best answer from the choices provided A B C D
Answer:more producers than consumers
The ecosystem has been defined as the level of organization of the biosphere that comprises the community. A healthy, balanced ecosystem has more producers than consumers. Thus, option c is correct.
What is an ecosystem?An ecosystem has been comprised of biotic and abiotic factors and establishes the interdependence of the living to the non-living. It comprises the ecological food pyramid and food chain that involves the flow of energy.
The producers of the food chain are the autotrophs that are more in number than the consumers as they are the primary source of the food and energy in the ecosystem.
The consumers are heterotrophs and depend on the producers for the food and energy and are lesser in number. This allows the ecosystem to be in balance as the requirements are fulfilled.
