Why are the Kreb's cycle and ETC
considered aerobic processes?
Answer:
Without oxygen, the electron transport chain becomes jammed with electrons. Consequently, NAD cannot be produced, thereby causing glycolysis to produce lactic acid instead of pyruvate, which is a necessary component of the Krebs Cycle. Thus, the Krebs cycle is heavily dependent on oxygen, deeming it an aerobic process.

- Chromosomes are made of DNA that contain genes that control the production of ______ within the cell.
Chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.
What is the significance of DNA as a blueprint?The DNA acts as a blueprint in which all of the cell's information is stored, such as in the form of a gene, which is later expressed in the cell in the form of polypeptides, proteins, enzymes, and so on by the translation process, and controls and regulates the cell for various functions. DNA contains lots of genes, but not all of them are expressible.
Hence, chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.

Name and describe 3 ways objects can travel across a membrane. Include what types of objects (H2O, sugar, ect) are moving across the membrane for each way.
Answer:
Osmosis - water
Ions - diffusion
Large proteins - endocytosis
Explanation:
Ions and small molecules can cross the cell membrane by simple diffusion, where they move from a high concentration to a low concentration, down a concentration gradient.
Osmosis is the process whereby water travels across a semi-permeable membrane from a high concentration to a low concentration.
Larger cargo can cross the membrane through a process called endocytosis, where the membrane engulfs the particles and brings them inside the cell, encased in a vesicle.
What is one reason scientists are trying to culture meat in laboratories instead of simply hunting or raising animals?
Answer:
Many reasons - but a really good question.
Explanation:
Cruelty - eating meat poses ethical issues to some people. They dont eat meat because they dont believe animals should be harmed. Growing laboratory meat takes away the need for slaughter.
Land used - a big issue with producing meat is the amount of land we need to raise cattle and to grow the food to feed cattle. Rainforest, woodlands, moorland have to be destructed to make way for pasture land for cattle. The food that cattle or animal eats also needs to be grown, which requires more land. Laboratory grown meat doesnt require all the pasture space for raising or feeding animals.
Water use - the amount of water that goes into producing meat is very high when compared to amount of meat that you get back. Water availability is another global issue that may be able to be addressed by lab produced meat.
When animals are reared from meat, they may be killed in unethical ways thereby making it ethically irresponsible to raise animals for meat.
Animals are widely used as food. This food from animals or having animal origin is known as meat. The ethical issues are of key importance in raising meat for food.

do you think a hand-crank flashlight would be a good energy system for the rescue workers? Why or why not?
Answer:
No.
Explanation:
No, hand-crank flashlight would not be a good energy system for the rescue workers because the light turns on by applying muscle force on the hand-crank flashlight and after that, the device convert muscle force into electric energy and the light turns on and we know that the rescue worker have a tough job which requires both hands so this hand-crank flashlight is not useful to him.

What macromolecules can be found in animal cells
and
What macromolecules can be found in plant cells
Answer:
ANIMALS: There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass.
PLANTS: The three main classes of macromolecules found in plants are thus proteins, polysaccharides and nucleic acids. However, mixed polymers are also known. such as the glycoproteins, which contain both sugars and amino acids in covalent linkage.
The macromolecules found in animal cells are carbohydrates, proteins, lipids, nucleic acids, and water. Each of these macromolecules has specific functions in the body of kingdom Animalia.
What are Macromolecules?Macromolecules may be defined as a molecule that contains a very large number of atoms that are held together by specific bonds.
The macromolecules found in animal cells are polysaccharides, proteins, nucleic acids, water, and some types of mixed polymers.
All such macromolecules perform specific functions in the structure of kingdom Plantae and meet the need for metabolic activities.

This organelle modifies and labels proteins so they will be working properly and arrive at the correct destinations? so whats the answer?
Answer:
[tex]\boxed {\tt Golgi \ apparatus}[/tex]
Explanation:
After a protein is produced on a ribosome it is sent to the endoplasmic reticulum. Here, proteins fold and then are sent to the golgi apparatus.
In this organelle, proteins are modified and labeled. Sugar groups (modifications ) and tags/signals (labels) can be added. From the golgi apparatus they are sent to different destinations or secreted.
So, the correct answer is Golgi apparatus.
Golgi apparatus
The Golgi apparatus, which is usually situated near the nucleus, receives proteins and lipids from the ER, modifies them, and then dispatches them to other destinations in the cell. Transport from the ER to the Golgi apparatus—and the Golgi can either move onward through the Golgi stack or, if they contain an ER retention signal, be returned to the ER; proteins exiting from the Golgi are sorted according to whether they are destined for lysosomes (via endosomes) or for the cell surface.

Schwann would make Statement II and Schleiden would make Statement III. Schwann would make Statement III and Schleiden would make Statement II. Schwann would make Statement IV and Schleiden would make Statement I.
Answer:
Schwann would make statement II and Schleiden would make statement III
Explanation:
Schleiden, a German botanist and Schwann was a zoologist, both have found that the plants and animals are made up of cells, they both shared their research and observation with each other and made the conclusion that all living organisms are made up of cells.
As mentioned above Schleiden was a botanist so he must have concluded and described that all plant organs are made up of cells, similarly as zoologist he proposed that the cell must function properly in an organism.
Answer:
B- Schwann would make Statement II and Schleiden would make Statement III.

If you took a 20-foot tree and hammered a spike into it 3-feet above the ground, how high would that spike be 30 years later when the tree is 100 feet tall? and why?
Answer:
The spike will remain at 3-feet above the ground in 30 years time because the spike does not increase in height as the tree does.
Please find the explanation below
Explanation:
Living things including the trees stated in this question are capable of growth (in height and girth). According to this question, a spike is hammered into a tree base at 3-feet above the ground level. However, after 30 years, the tree grows to 100 feet but the spike will remain at 3-feet above the ground.
This is because the spike, which is naturally incapable of growth, will not grow alongside the tree. A plant (tree) undergoes growth at its apices or meristem i.e. the tree will elongate from the tip and not any other part. Hence, the tree will grow and leave the spike at its initial level.
