In a DNA strand, 80% of the strand is made up of adenine and thymine. How much adenine, thymine, cytosine, and guanine is made up in the strand
Answer: The perecentage of guanine is 30%
Explanation:
According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.

Where did the energy for the grain explosion come from?
Answer:
Grain dust is the main source of fuel for explosions in grain handling. Grain dust is highly combustible and can burn or explode if enough becomes airborne or accumulates on a surface and finds an ignition source (such as hot bearing, overheated motor, misaligned conveyor belt, welding, cutting, and brazing).

What traits would make this species more “fit”??
Answer:

a squirrel dropped an acorn from a branch of an oak tree. which of these will change as the acorn falls from the tree to the ground? the mass of the acorn the density of the acorn the force of the acorn the velocity of the acorn
As an acorn is dropped form a branch of an oak tree, the force applied on the acorn changes which results in the dropping off of acorn seed. Thus, the correct option is C.
What is Force?A force is a push or a pull which changes the motion of an object. The fundamental forces are of four types such as: Gravity, Electromagnetism, Strong interaction, and Weak interactions.
Here, Gravitational force or gravity is applied during the dropping of an acorn seed form the oak tree. In some plants, seeds simply drop off on their own. However, some plants rely on the gravity to disperse off their seeds for pollination and other purposes. Seeds from the poppy plant emerge from their fruit such as a pepper drops from a shaker which allows a plant to form the colony around it.
Therefore, the correct option is C.

A student wants to find the benefit of a certain structural trait in mice. What is the first step the student should follow?
A. Design a classroom experiment.
B. Generate a graph of the results of this experiment.
C. Breed me with and without the trait together.
D. Observe the survival rate of mice with the trait in nature.
Help ASAP please
The answer is A. Design a classroom experiment as a first setup starts with an experiment.
Design of experiments, also known as randomized experiments, is characterized by two distinctive features: (i) the deliberate manipulation of treatment, or more generally, the independent variables of interest to the researcher, and (ii). Random assignment of units to treatment and control groups.
What is a mice trait experiment?Studies in mice allow mothers to pass traits to their offspring via bacterial DNA. Summary: A new study in mice has shown that the DNA of bacteria inhabiting the body can pass traits to offspring in a manner similar to that of the parents themselves.
Hence concluded that mice trait is to be performed first.

What are some water pollution management strategies, what do you think is the best one and why?
Answer:
There are plenty of things that we as individuals can do to slow down the amount of pollution going into the ocean, these could include not flushing anything down the toilet that won't disintegrate (because no matter where you live, all toilet pipes lead to the ocean), converting plastic use to reusable materials; this could include using reusable straws, water bottles, shopping bags, etc. and of course, when you need to throw plastic out, always recycle. :)
Explanation:
I believe the best way an individual can help the oceans is by converting plastics to reusable or at least eco-friendly products. If everyone made a conscious effort to do this, the oceans would be MUCH clearer.
Hope this helps!

urinary bladder, kidney, ureter, urethra
O kidney, urethra, urinary bladder, ureter
O urinary bladder, ureter, kidney, urethra
O kidney, ureter, urinary bladder, urethra
Answer:
Kidney, ureter, urinary bladder, urethra
Explanation:
Kidney, ureter, urinary bladder, urethra is the correct sequence of the urine's pathway as it is formed and exited from the body. Therefore, option (D) is correct.
What is Urinary tract?Urine, which contains wastes and extra fluid, is expelled from the body through the urinary tract, which serves as the body's drainage system. Urine is removed through the urinary tract. In order for normal urination to take place, it is necessary for all of the body parts that make up the urinary tract to cooperate with one another and do so in the appropriate sequence. The component of the body that processes urine and consists of two kidneys, two ureters, a bladder, and a urethra.
Infections can also occur in the urinary tract, and these infections are caused by microorganisms, most commonly bacteria, that enter the urethra and the bladder. These microorganisms are what cause inflammation and infection in the urinary tract. Even though a urinary tract infection (UTI) most frequently takes place in the bladder and the urethra, bacteria are able to travel up the ureters and infect your kidneys if they have the chance.
