For what purpose do lipids accumulate in connective tissue?
Answer:
the lipids accumulate in connective tissue is used for complex cleaning purpose
Lipid accumulation product (LAP) is an index, which combines waist circumference (WC) and triglyceride (TG) reflecting lipid accumulation. Lipids are available to the body from three sources. They can be ingested in the diet, stored in the adipose tissue of the body, or synthesized in the liver. Lipid storage (especially sphingolipid and unesterified cholesterol) is found in liver and spleen. In the brain, glycolipid storage predominates, often with some decrease in myelin white matter. The condition is inherited as an autosomal recessive trait.
Hope that this can help in some form or fashion :)

What is volume?
Describe the standard units of liquid volume.
What is mass (weight)?
Describe the standard units of mass.
Answer:
Explanation:
1. "Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre. "
2. "In the CCSS, the unit of liquid volume introduced in Grade 3 is liter (L), which is a standard unit in the metric (or SI) system. Another commonly used unit of liquid volume is milliliter (mL), where 1000 mL = 1 L. Many soda bottles are 500 mL, 1L or 2L."
3. "The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it."
4. "The standard International System of Units (SI) unit of mass is the kilogram (kg). The kilogram is 1000 grams (g), first defined in 1795 as one cubic decimeter of water at the melting point of ice."

which cell organelles are known as secretary vesicles
Answer:
the membrane
Explanation:
Secretory vesicles are tiny little packages in which certain cell secretions can be transported. The vesicles are membrane bound and produced by the golgi apparatus or endoplasmic reticulum. Most vesicles will have specialized functions and specific materials which they transport. In addition to transportation, secretory vesicles can store or digest certain secreted molecules. Synaptic vesicles store neurotransmitters, hormones are stored in secretory vesicles for release into the blood stream, and enzymes are also stored in secretory vesicles to be used when needed to make cell walls in certain plants, fungi, and bacteria. The release of the substances inside of the secretory vesicle can be stimulated by a neural or hormonal signal. The membrane of the vesicle can then fuse with the membrane of the target cell and essentially spill its contents. The vesicle then adds its membrane to that of the target cell. This is typically temporary until another vesicle is created when certain components are then removed from the cell.
Have you ever sat around a campfire or watched flames flicker in a fireplace? The burning of wood is a chemical reaction. A chemical reaction always involves changes in chemical bonds that join atoms in compounds. The elements or compounds that enter into a chemical reaction are called reactants. The elements or molecules produced by a chemical reaction are called products. As wood burns, molecules of cellulose are broken down and combine with oxygen to form carbon dioxide and water vapor, and energy is released. What are the reactants when wood burns? What are the products when wood burns?
Answer:
The correct answer is -
Reactants - oxygen and cellulose.
Products - carbon dioxide and water (carbon residues sometimes)
Explanation:
Burning wood is a chemical reaction that involves a reaction between reactants and produces products with energy. In this chemical reaction, the reactants that take part are oxygen present in the atmosphere and cellulose (wood made up of cellulose).
In this reaction a lot of energy or heat loss takes place and at the end of the reaction carbon dioxide and water produces. however, sometimes other substances also present.

How are detritovores different from decomposers?
a. Detritovores eat the detritus, decomposers break down dead material into detritus
b. Both detritovores and decomposers do the same thing, they are not different.
c. Decomposers eat detritus that the detritovores make.
d. Decomposers always eat dead material and detritovores sometimes use photosynthesis to get energy.
Answer:
I think it's option B
Explanation:
Decomposers like bacteria and fungi don't eat their food, they decompose it externally. Also, decomposers consume nutrients on a molecular level while detritivores eat large amount of decaying material and excrete nutrients.

(c) Many bacterial diseases can no longer be treated with antibiotics. Outline how
antibiotic-resistant strains of bacteria can develop.
Antibiotics kill or inhibit the growth of susceptible bacteria. Sometimes one of the bacteria survives because it has the ability to neutralize or escape the effect of the antibiotic; that one bacterium can then multiply and replace all the bacteria that were killed off. Exposure to antibiotics therefore provides selective pressure, which makes the surviving bacteria more likely to be resistant.

Part A of the cell membrane is composed of which of the following?
Choose 1 answer:
Choose 1 answer:
(Choice A)
A
The hydrophobic tails of the phospholipid molecules.
(Choice B)
B
Proteins attached to the heads of the phospholipid molecules.
(Choice C)
C
Both the heads and the tails of the phospholipid molecules, arranged randomly.
(Choice D)
D
The hydrophilic heads of the phospholipid molecules.
Answer: A: The hydrophobic tails of the phospholipid molecules.
Explanation: The hydrophobic, or ''water-fearing,'' fatty acid tails face inward, trying to get away from the aqueous solution found on either side of the cell membrane. Hope this helped have a nice day. :)
The cell membrane is composed of the hydrophobic tails of the phospholipid molecules. Therefore, option (A) is correct.
What are the functions of cell membrane?The identification, communication, regulation of solute exchange through the membrane, and isolation of the cytoplasm from the external environment are the four primary functions of the plasma membrane.
Membranes in biology serve three primary purposes: they prevent harmful substances from entering the cell; they have receptors and channels that make it possible for specific molecules, like ions, nutrients, wastes, metabolic products, and toxins, that mediate cellular and extracellular activities.
The substance's entry and exit from the cell are controlled by the membrane, which is selectively permeable. Protection from the external environment is one of the functions.

Answer:
The fluid mosaic model
Explanation:
The fluid mosaic model describes the structure plasma membrane as a flexible barrier that contains various different components (a mosaic). These components include the phospholipid bilayer, as well as the proteins and other lipids and carbohydrates that are embedded in it. These different components give the membrane its fluid characteristics.

48 cm
You may use scratch paper or you Windows calculator.
1 = 46 cm
w20 cm
Answer:
44160
Explanation:
Volume = Length X width X height.
Therefore, 46 X 20 X 48 = 44160 cm3
What is volume of a substance?Volume of a substance is defined as the space it occupies. Length, width and height of a substance are taken into consideration for measuring volume. Thus, volume is a three dimensional quantity.
It is the product of length, width and height of a substance. Volume is expressed as unit per cube. The SI unit for volume is m3.
It is possible to calculate the density of matter, if the volume and mass of the substance is known.
Here, to find out volume of a computer; the product of length (46cm), width (20 cm) and height (48 cm) is taken.
Therefore, the answer is 44160 cm3.
