Cytoplasm contains the cytosol, microfilaments and other support structures in the cytoskeleton; it holds parts of the cell together.
What is cell wall?Cell wall is the rigid outer layer of the cell; this forms a protective wall made mostly of cellulose, a structural carbohydrate. It maintains the shape of the cell by preventing water loss. Vacuole a phospholipid membrane bound organelle plays a structural role in the cell; supports the cell membrane by exerting turgor pressure.
Arranged in a phospholipid bilayer, the cell membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.
The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.
Therefore, Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins.

You are a scientist and would like to know if a new fertilizer will help plants grow faster. What would the control group be?
A)The group that gets only water, no fertilizer
B)The group that gets water and fertilizer
Answer: The group that gets only water no fertilizer
Explanation:
The control group does not have an additive
The control group will be the group that gets only water, no fertilizer. Thus, option A is correct.
What is function of fertilizer ?
An additional organic or inorganic substances which is added to soil or plants to increase the crop productivity is called as fertilizer.
It contain plant growth promoting nutrients like nitrogen, potassium, and phosphorus; For example, urea, anhydrous ammonia, etc.
The organic fertilizer is derived naturally from plants and animals. It enriches the soil nutrient level, encourage microbial reproduction.
Organic fertilizers are Agricultural Waste, Manure, municipal sludge etc.
Inorganic fertilizers generated chemically contain inorganic nutrients for crop growth; It can be up two types.
Nitrogen fertilizers where nitrogen is the primary element as it is constituent of chlorophyll, maintain the process of photosynthesis, thus improve the crop production.
Phosphorus fertilizer, increases the plant root growth as the protoplasm of the cell contains phosphorus, important for cell growth and proliferation.
Thus, option A is correct.

Most functions of a prokaryotic cell are controlled by the cell's nucleus. True or false?
Answer:
False.
Explanation:
A prokaryotic cell doesn't even have a nucleus.
A student examining an unknown cell under a microscope notes it has a cell wall, cytoplasm, and genetic information contained within a nuclear membrane. Which inference would be correct?
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
Answer:
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic
Explanation:
Since the cell possesses a cell wall and genetic information, it has to be an animal cell.
-this is a plant cell because of the cell wall
Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.
-prokaryotes don't have DNA contained in a nuclear membrane
Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.
- DNA contained in a nuclear membrane --> eukaryototic
- cell wall --> plant cells, which are eukaryotic
Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell
-DNA is contained in a membrane should not lead to the conclusion that it's a plant cell, as it could be an animal cell too

A company wants to build a new store. After reviewing the piece of land it is determined that a threatened woodpecker nests in that area .If the company is granted permission to build , what is the most environmentally responsible action by the company
Answer:
Explanation:
If the piece of land is forested or covered with many trees, the company can decide not to bring down all the trees (leaving some trees standing) and move as many as possible nests to the available trees within it's land. This will prevent emigration of the woodpeckers and can ultimately help conserve the woodpeckers in that land and indeed the area in which the land is situated.
This is most environmentally friendly because killing or scaring away of the birds by destroying there homes could lead to imbalance in the environment and even cause gradual extinction of the birds in the environment/area.

The Earth's biodiversity is determined by the variety of all living organisms on Earth. In recent years, ecologists and other scientists have encouraged the preservation of global biodiversity through the protection and management of natural ecosystems. Preserving the biodiversity of the Earth is important because
Answer:
The Earth and its Biodiversity is a living laboratory
Explanation:
The importance of preserving Earth's Biodiversity remains on the idea that every single living organism that existed here on Earth is an example of how Nature can express itself. This means that we as humans can learn with every mechanism that has been developed through millions of years and apply to our self been.
Answer:
all of these
Explanation:
The preservation of the biodiversity of the Earth is important for many ecological, economic, and cultural reasons.
Biodiversity increases ecosystem stability for a given type of ecosystem because greater species diversity ensures natural sustainability of all life forms within the ecosystem. Ecosystems are also highly interconnected and the removal of even a few species can cause ecosystem disruption.
The organisms of Earth's ecosystems provide services that humans cannot replicate. These ecosystem services include the generation of soil that is typically done by microbial and animal species, the maintenance of air quality that is done by plants, the decomposition of wastes that is done by the Earth's decomposers, and the maintenance of water quality that is done by wetland ecosystems.

Which of the following is not a key ingredient in cloud formation?
particles. drizzle. water vaper. drop in air pressure
Answer:Drizzle
Explanation:
Clouds require water vapor, particles the vapor can condense around, and a drop in air pressure to form.
Cloud formation is a process that begins with a drop in air pressure. An ingredient that is not key in the formation of clouds is;
A. DrizzleDrizzle is not an important factor in the formation of clouds. Clouds are formed when water and ice are suspended in the air.
The process of cloud formation begins when the terrain is heated up by the sun.
Wind blows more around the areas of low pressure thus causing the rising of warm air which holds up water.
After some time, this air becomes condensed and falls down as rain.
Summarily, Drizzling is not an important part of cloud formation.
