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.
7. What are the three parts of Chargaff's Rule?
plz help!!
Answer:
Chargaff rule: The rule that in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine.)
Explanation:
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.
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.

Which of the following is an example of selective permeability?
a magnet
a window screen
a milk jug
a bottle rocket
A window screen is an example of selective permeability.
• Selective permeability is a characteristic and function of the cell membrane, which plays an important role in sustaining homeostasis by monitoring the passage of certain substances while inhibiting others from invading the cell.
• Of the given options, a window screen is an example of selective permeability.
• A window screen is also known as the bug screen, insect screen, wire mesh, or fly screen is created to cover the window opening.
• It is generally a mesh formed of fiberglass, metal, pieces of plastics, plastic wire, and pieces of metal or wood.
• It functions to prevent the entry of bugs, birds, debris, and other animals into the building, however, it does not prevent the entry of fresh air.
Thus, a window screen is an example of selective permeability.

Explicación:
El ciclo cardíaco consta de dos períodos i. mi. La diástole es aquella durante la cual el músculo cardíaco se relaja y se llena de sangre, mientras que la sístole es un período de contracción y bombeo de sangre. La diástole ventricular es el momento en el que las dos cámaras inferiores del corazón conocidas como ventrículos se relajan para permitir que la sangre fluya hacia adentro. La diástole auricular es el momento en que las dos cámaras superiores del corazón llamadas aurículas se relajan y permiten que la sangre fluya en.

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.

#SPJ6
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.

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.
