How do lipids differ from one another in function?

Biology

Answer:

The three fatty acids can be different from one another. Since the hydrocarbon chains are very non-polar, fats do no dissolve in water; instead, fat molecules tend to coalesce with one another. Since a fat molecule has 3 fatty acids connected to a glycerol molecule, they are also called triglycerides.

The two main types of fermentation are alcoholic fermentation and lactic acid fermentation. In an alcoholic fermentation, the main product of this process is ethyl alcohol. Lactic acid on the other hand has lactic acid as its main product. When muscle cells run out of oxygen, lactic acid fermentation would commonly take place.

Answer:

The options

A. Personal mortality

B. Inevitability

C. Purposefulness

D. Organicity

The CORRECT ANSWER IS A.

A. Personal mortality

Explanation:

Universality

It as to do with the fact that all living things must gradually or at some point die. It sees Death as an all-inclusive, inevitable, and unavoidable.

A. personal mortality✔✔✔

It is the concept that death applies to oneself, that not only do all living things die but each and every living thing will surely die.

B. Inevitability❌

It is the concept that all living things must one way or the other encounter death.

C. Purposefulness❌

It has to do with death and it's purpose.

D. Organicity❌

It is the probable etiology of the inadequacy of full eyelid closure at death.

Explanation:

Plant cells: (1,3,5,6)

Plant cells differ from animal cells in several ways.

Cell wall: One of the most defining one is plant cells have cell walls. These cell walls are rigid and they cover the plasma membrane of the plant cell. Cell walls have 3 layers and the outermost one is called the middle lamella, which is the cell cement. It acts like a cement because it is what holds one plant cell and the adjacent cells together. The middle lamella is made up of pectin.

The cell wall also has layers made up of cellulose, which happens to be a macromolecule as is the most abundant of its kind on Earth. They form bundles called microfibrils.

Chlorophyll: Chlorophyll are molecules found in plant cells that play a role in food production in plants. Chlorophyll absorbs sunlight which is used in the process of food making called photosynthesis, along with other elements like water and carbon dioxide. Also chlorophyll gives the green pigmentation of plants.

Chloroplast: Chlorophyll are encased in an organelle called chloroplast. Chloroplasts are where photosynthesis takes place. They are found in the leaves of plants. Because they use chlorophyll, the are also green.

Other parts of a cell: (4, 9,11.15, 16, 17)

Both plant and animal cells also have similar organelles.

Endoplasmic Reticulum (ER): There are two types: smooth endoplasmic reticulum(SER); and rough endoplasmic reticulum(RER). The SER acts like a storage unit for lipids and steroids. They also help in the production as well. RER is a pckaging and synthesis area. It is rough because they have ribosomes on them.

Ribosomes: Ribosomes are small organelles in the cell that are partly made up of rRNA or ribosomal RNA. They play an important role in protein synthesis. They help translate the DNA code that the mRNA transcribed to determine what type of protein will be formed.

Golgi Apparatus: Also known as the golgi complex, is an organelle in the cell that serves as a sorting and packaging area. It collects simple molecules and packages them into more complex molecules which would be stored if the cell would need it, or it will be sent out of the cell. These complex molecules are packed into vesicles. A transition vesicle is made from the protein in the ER is transported to the golgi apparatus, which then processes its contents. It then releases a secretory vesicle, that is then brought to the cell membrane.

Centrioles: Centrioles are small, cylinder-shaped organelles that aid in cell division. They are made up of the protein, tubulin. These centrioles produce spindles or spindle fibers that pull on the chromosomes during cell division and split them up.

White blood cells, part of the ___________ system, work closely with the ___________ system to protect us from infection and dis

tresset_1 [31]

Answer: The correct answer for the fill in the blank is A) Circulatory, immune.

Circulatory system also called cardiovascular system is a vast network of organs and vessels that allow the circulation of blood so as to transport nutrients, oxygen, other gases, and hormones to different parts of the body.

Blood contains different cells like white blood cells, red blood cells, platelets.

White blood cells ( also called leukocytes) work closely with immune system. They provide defense against pathogen ( disease causing organisms) through various ways ( like ingesting foreign material, producing antibodies to clear the antigens). By doing so, they protect us from infection and disease.
