Describe the function of the following
organelles:
a. Nucleus-
b. Cell membrane-
c. Chloroplasts-
d. Cell Wall-
e. Cytoplasm-
Answer:
Explanation:
The nucleus is the part of the cell that controls all other functions of the cell and the organelles. It also contains DNA.
The cell membrane acts as a semipermeable barrier between the cell and the outside environment to facilitate active and passive diffusion, and to maintain the concentration of solutes inside the cytoplasm. It also has receptors on its outer surface to communicate with other cells.
Chloroplasts use energy from photons of light from the sun to undergo photosynthesis, which helps the cells create glucose, or in other words, make its own food (in plants).
The cell wall protects plant cells from antigens and, due to its boxy shape, also helps the plant have a more rigid structure so that plants can stand upright.
The cytoplasm of a cell is the fluid within the cell membrane through which organelles in the cell move around. It is also the location where glycolysis typically takes place. The cytoplasm is mostly water with salts dissolved into it.

Potatoes can be genetically modified so that they are _________ to plant-eating beetle?
A. Toxic
B. Tacky
C. Tasty
D. None of these
Answer:
A or D
Explanation:
You would want to genetically modify the plant so that the beetles wouldn't want to eat it. If it is toxic, the bugs would stay away from it. However, you could also just modify the plant so that it doesn't taste good for the bugs, in which case you should pick D. Choose whichever answer you think is best.
Why are plants and animals able to survive in the tundra?
The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.
What is tundra region?Snow covers tundra lands for the majority of the year, but summer provides bursts of wildflowers.
The small plants of the tundra employ dormant strategies, producing seeds only occasionally, turning with the sun to absorb energy, and growing protective coverings.
The ability to build subterranean insulated tunnels as well as heavy winter coats, seasonal color-changing camouflage, and efficient body shapes have all been developed by animals that live in the Arctic tundra.
Therefore, The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.

Answer: Plants and animals are able to survive in the tundra because they have adaptations that allow them to thrive in the harsh conditions of the Arctic and sub-Arctic regions. These adaptations include thick fur or feathers to insulate against the cold, small body size to minimize heat loss, and the ability to store food and nutrients during the short growing season. Additionally, many tundra plants have shallow roots that can absorb nutrients quickly when they are available, and some have developed the ability to photosynthesize at low temperatures and with minimal sunlight.

The children in a middle school classroom are all exposed to chicken pox one week. Among these students are John, who had chicken pox when he was much younger, and Sara, who has never had chicken pox. Which student do you expect would be less likely to become ill with chicken pox following this exposure and why? (5 points) John: he has naturally acquired active immunity to chicken pox from his previous exposure. Sara: she has naturally acquired passive immunity to chicken pox from exposure to other students. John: the pathogens that cause chicken pox will no longer be able to enter his body. Sara: since she has not suffered from chicken pox, her immune system is probably stronger than Johns.
Answer:
John: he has naturally acquired active immunity to chicken pox from previous exposure.
Explanation:
Your body naturally has some immunity to things that aren't you, but when you get sick with a specific pathogen, your body begins to make antibodies that specifically recognize that pathogen. Each antibody only recognizes one pathogen, and it floats around waiting to find it again so it can tell your body to kill it before you get sick again. This is why we become immune to chicken pox; after the first time you beat it, your body has the labeled antibodies and it can quickly destroy the pathogen before you get sick again.
Answer:
John: he has naturally acquired active immunity to chicken pox from his previous exposure.
Explanation:
Ok, I know this is incredibly late and doesn't matter anymore, but I just wanna say that the person before me was correct. I just took the test and this was the correct answer.

What is base pairing? (and Chargaff's rule)?
Answer:
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G).
Explanation:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

Can you use mass alone to predict whether an object will sink or float? Explain.
Answer:
No, you need both mass and volume to determine its desity to see if it can float.
Explanation:
Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.

Explanation:
which two body systems interact to expel the waste product carbon dioxide
a urinary system
b nervous system
c excretory system
d circulatory system
Answer:
excretory system and circulatory system
Explanation:
Blood is part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.
