Answer: With my knowledge about the molecular structure of water which states that water is made up of two (2) molecules of hydrogen one (1) molecule of oxygen, ice forms on the top of a lake through a distinct means.
When an Ice forms,the hydrogen atom of one water molecule will then form a weak hydrogen bond with the top of the oxygen atoms of two (2) other of the water molecules.
Thereafter, lining up the water molecules in this designated pattern takes up more space than having them randomly in a jumbled manner just as in the case of water in liquid form.
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.
Explanation:
Understand?
Answer:
Explanation:
1.carbon and hydrogen with nitrogen, oxygen, sulphur, and phosphorus.
2.a polymer is a collection of a large number of molecules whereas monomer is a single molecule

What causes cystic fibrosis?
Answer:
Cystic fibrosis is caused by a change, or mutation, in a gene called CFTR (cystic fibrosis transmembrane conductance regulator). This gene controls the flow of salt and fluids in and out of your cells. If the CFTR gene doesn't work the way it should, a sticky mucus builds up in your body.

Assume in otters short hair (L) is dominant to long hair (l) and black hair (B) is dominant to brown (b). If you found a black short-haired otter, you could determine its genotype by crossing it to another otter with a genotype of:
Answer:
llbb
Explanation:
The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be llbb.
Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.
If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.

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.
Thus, Some autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.

Which is a malignant disorder of mature antibody-secreting B lymphocytes or plasma cells? Multiple myeloma Hairy cell leukemia Acute lymphoid leukemia (ALL) Chronic myeloid leukemia (CML)
Answer:
The correct answer is Multiple myeloma.
Explanation:
Multiple myeloma is a type of bone marrow cancer caused by a malignant degeneration of plasma cells. Normal plasma cells are part of the immune or immune system, responsible for dealing with infections and diseases of external origin. Plasma cells are normally found in the bone marrow, mixed with other cells of the immune system and with the cell-producing cells of the blood. When there is an infection, the B lymphocytes respond, become plasma cells or plasma cells and produce antibodies (also called immunoglobulins) that help the body fight infection. T lymphocytes respond with various transformations that allow them to directly attack infectious agents or help other types of cells defend the body.

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.
Which statement describes one feature of Rutherford’s model of the atom? The atom is mostly empty space. The atom cannot be divided into smaller particles. Electron clouds are regions where electrons are likely to be found. The electrons are located within the positive material of the nucleus.
Answer: The atom is mostly empty space.
Explanation:
Before to Rutherford, the accepted model for the atom was Thomson's model:
The atoms were a positive sphere, with electrons occupying space in it".
This was called the "plum pudding model".
Then came Ernest Rutherford, and he created a model where the atoms are mostly empty space (void) with a positive charged nucleus (really compressed in the center), and the electrons were orbiting around it.
Then the correct option is that the atom is mostly empty space.
Answer:
The atom is mostly empty space

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"

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.

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.

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.
Therefore, option c. more producers than consumers are the correct blank.
