HELP FAST ! People donate bone marrow so that those in need can produce:
O bones and fat
O fat and muscles
O blood and fat
O bones
Answer:
blood and fat
Explanation:
if it's for the Connexus test, I just did it and the correct answer is blood and fat.
Through the bloodstream of the patient, these given cells travel to the bones. The new blood-forming cells will be created here using the donor cells. Thus, option C is correct.
What is bone morrow donation?The patient does not experience a lot of pain during the treatment. After the anesthetic goes off, the donor can feel pain. Painkillers can be required for the upcoming days.
Collagen, which is rich in bone marrow, helps to maintain and strengthen the skin and bones. The donor is infused into the patient's bloodstream during a transplant.
It is also high in glucosamine, a substance that prevents osteoarthritis, eases joint pain, and lowers joint inflammation.
Therefore, people donate bone marrow so that those in need can produce blood and fat.

The water level of Lake Michigan was once 18 meters higher than it is today. As the water level fell, land was exposed. Many small lakes or ponds were left behind where there were depressions in the land. Below are illustrations and descriptions of four ponds as they exist today.
Pond A: Cattails, bulrushes, and water lilies grow in the pond. These plants have their roots in the bottom of the pond, but they can reach above the surface of the water. This pond is an ideal habitat for the animals that must climb to the surface for oxygen. Aquatic insect larvae (food for larger insects, which in turn are food for crayfish, frogs, salamanders, and turtles) are abundant.
Pond B: Plankton growth is rich enough to support animals that entered when the pond was connected to the lake. Fish make nests on the sandy bottom. Mussels crawl over the bottom.
Pond C: Decayed bodies of plants and animals form a layer of humus over the bottom of the pond. Chara, branching green algae, covers the humus. Fish that build nests on the bare bottom have been replaced by those that lay their eggs on the Chara.
Pond D: The pond is so filled with vegetation that there are no longer any large areas of open water. Instead, the pond is filled with grasses. The water dries up during the summer months.
Questions:
Succession 1 – Drying of a Pond
1. Write the letters of the ponds in order from the youngest, to the oldest.
2. As the ponds undergo succession, what is happening to the type and number of organisms?
3. Black bass and bluegill make their nests on sandy bottoms. In which pond would you find them?
4. What will happen to the black bass and blue gill as the floor of the ponds fills with organic debris?
Answer:
1- BCAD
2- They grow and diversify
3-B

5- They will die
Within a plant leaf, most photosynthesis occurs in cells called ______ cells, which are often interspersed with air spaces to maximize gas exchange.
Answer:
The spongy mesophyll is the kind of cell described.
Explanation:
"Most of the interior of the leaf between the upper and lower layers of epidermis is a parenchyma(ground tissue) or chlorenchyma tissue called the mesophyll (Greek for "middle leaf"). This assimilation tissue is the primary location of photosynthesis in the plant."
The main layers of the leaf are the cuticle, which is the "skin," the palisade mesophyll (the second topmost layer of cells), the spongy mesophyll, which is lower, and the lower cuticle. The spongy mesophyll is so called because it consists of leaf cells interspersed with air, which maximises their access to oxygen.

how can you prove that arteries and veins in the heart function differently when compared to the rest of the body?
Answer:
Explanation:
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.
Answer:
Arteries are thicker and stretchier to be able to handle the higher pressure of blood moving through them. Veins are thinner and less stretchy. This structure helps veins move higher amounts of blood over a longer time than arteries.
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.

Describe the function of sensory neurons. What do sensory neurons do in your body?
Answer:
Answer in explanation.
Explanation:
Sensory neurons are nerve cells that are triggered by sensory input from your surroundings. Let's say you touch a hot object with your fingers. This causes sensory neurons to activate and transmit messages to the rest of the nervous system about what they've discovered (which is that the object is hot).

Circular dna not part of a bacterial genome is called a plasmid.
What is plasmid?
A plasmid is a small piece of extrachromosomal DNA that is contained within a cell. It is distinct from the DNA of the chromosomes and has the ability to multiply without help from the chromosomes. Plasmids are most frequently found in bacteria, where they take the form of small, circular, double-stranded DNA molecules. However, archaea and eukaryotic cells can also occasionally contain plasmids.
Plasmids are naturally found in the cells of bacteria, and they can also be found in the cells of some eukaryotic organisms. Plasmids are often responsible for conferring genetic benefits on bacteria, such as resistance to antibiotics, because the genes they carry.
Therefore,circular dna not part of a bacterial genome is called a plasmid.
