Why does ice become less dense than water?

Answers

Answer 1
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

The geological time scale/species scale is divided into different units of time depending on changes in the rocks and fossils. So the statement is true.

What is the geological time scale?

The lengthy period of time that the Earth's geologic history has taken up is known as geologic time. Starting at the beginning of the Archean Eon (4.0 to 2.5 billion years ago), formal geologic time runs to the present.

The Hadean Eon, an informal time period that runs from around 4.6 billion years ago (corresponding to Earth's first creation) to 4.0 billion years ago, is also frequently included in modern geologic time scales. The period of Earth's history that is reflected by and preserved in the planet's rock layers is known as geologic time.

Events throughout Earth's history are "calendared" according to the geologic time scale. It divides all of the time into named units of abstract time known as eons, eras, periods, epochs, and ages, in declining order of duration. Those geologic time units are counted according to stratigraphy, the correlation, and the categorization of rock layers.

Therefore, the geological time scale is used for dividing different units of time according to changes in rocks and fossils. Hence the statement is true.

John is completing an internship in biology at the Clearwater Marine Aquarium. While interning there, he monitors an outdoor phytoplankton exhibit to observe how populations of phytoplankton change when exposed to light. It is observed that each year the phytoplankton population within the exhibit increases when it was exposed to high amounts of sunlight. A new apartment complex that overlooks the aquarium is being built. The phytoplankton that were receiving 8-12 hours of sunlight each day will now have between 2-5 hours of sunlight. How will the phytoplankton be affected by the new apartment building?

Write a paragraph describing the function of the endomembrane system? Include these terms: DNA, RNA, Ribosome, Endoplasmic Reticulum, Golgi Apparatus, plasma membrane, secretory vesicle, free ribosome, bound ribosome, protein.

Answers

Answer:

Please find the function of the endomembrane system below.

Explanation:

The endomembrane system is a system of membranous organelles in eukaryotic cells which plays the collective role of synthesis, modification, packaging and transportation of lipids and proteins within the cell. The organelles involved are endoplasmic reticulum, Golgi apparatus, vesicles and plasma membrane.

DNA, which is the genetic material in living cells encodes genetic information. The information in DNA is transcribed in the nucleus into a RNA molecule, which is then translated in the ribosomes (organelle for protein synthesis) into PROTEINS. Ribosomes can either be free or membrane-bound depending on whether it produces proteins that are used in the cell or are exported out of the cell respectively. However, ribosomes are attached to the surfaces of endoplasmic reticulum making them called ROUGH ENDOPLASMIC RETICULUM. This makes rough endoplasmic reticulum associated with protein production/synthesis.

The synthesized proteins is then packaged and modified in the GOLGI APPARATUS, after which it is transported by SECRETORY VESICLES that transports it to the PLASMA MEMBRANE for exocytosis.

How can a shortage of nutrients harm organisms in an ecosystem? How can an excess of nutrients harm organisms in an ecosystem? Give an example of each scenario to support your answers.

Answers

Answer:

Explanation:

Shortage of nutrients in an ecosstem can harm an organism because when nutrients are scarse or very limited for organism and did not meet up with the organism requirements, there will be reduced metabolism and this can cause malfunction. Shortage of nutrients can lead to decline in growth and can lead to spring up of some diseases in the organism because enough nutrients us not available for good metabolic processes and fight diseases.

For example when an organism is deficient in vitamins and carbohydrates, the organism will not have energy to power metabolic processes and for it's activities and vitamins deficient will make the organism not to have the ability to fight against disease.

Too much of nutrients also affect organisms negatively. When there is much build up of nutrients, it can be harmful to the organisms and restrict metabolic processes.

For example too much of nutriwnts like too much of fat can block blood artieries and veins and thus can lead to inability of blood to flow .

B. The native snail species will move to another area allowing the ecosystem to remain stable.

C. The native snail species will share their food with the invasive species stabilizing the ecosystem.

D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem ​

Answers

Answer:

D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem ​

Explanation:

In Ecology, an invasive species refers to a species of organism that is foreign i.e. non-native to a particular habitat or environment. They are characterized by the ability to proliferate in growth and compete for space and nutrients with the native species in the habitat they are introduced to.

In this case, the giant african land snail, which is an invasive species, if introduced into a stable ecosystem will compete for resources with the native species of that ecosystem leading to the destabilization of the ecosystem.

When fungi and bacteria decompose organic matter, they return ____ to the environment.

Answers

Answer:

Carbon and nitrogen.

probably

Hope that helped :)

Fungi and bacteria decompose organic matter, contributing to the formation of soil organic matter since they return nitrogen and carbon to the environment.

How is the decomposition of organic matter?

Fungi and bacteria break down residues and organic matter, excess nutrients (nitrogen, phosphorus and carbon) are released into the soil in forms that can be used by plants (nutrient availability).

The nitrogen released by these microorganisms is in the form of ammonium (NH4+) and thus readily available to the roots of plants and other organisms.

By decomposing residues and storing carbon within their own biomass, soil biota play a very important role in nutrient recycling processes.

Therefore, we can conclude that the most important function of fungi and bacteria microorganisms is the breakdown of organic materials.

30 POINTS!! Type one to two paragraphs describing the full water cycle. Be sure to use full sentences and proper grammar.

Answers

Answer:

      The water cycle is the way that all water chases after as it moves Earth in various states. Fluid water is found in seas, streams, lakes—and even underground. Strong ice is found in icy masses, day off, at the North and South Poles. Water fume—a gas—is found in Earth's air.

        The water cycle, otherwise called the hydrologic cycle or the hydrological cycle, depicts the constant development of water on, above and underneath the outside of the Earth. There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).

Predict the two possible outcomes if temperature or pH were changed within the molecular control system of cell division.

I'm pretty sure it's that the cells would divide more or divide less, right? Because the temp or pH change would cause some enzymes to denature, and then, depending on which ones denature, the regulation of cell division would be messed up and they would either divide too much or not enough?

Answers

Answer:

Yes, pH and temperature affects the cell division.

Explanation:

If the temperature falls between the range of 3 °C to 25 °C, the mitosis process increases but when the temperature lowers from 3 °C and exceeds from 25 °C so it decreases the rate of mitosis process because the enzymes which is responsible for the process of mitosis denatures and does not work properly. same is the case with pH, the rate of the process will increase when the pH is neutral but decreases when the pH goes lower or higher.
