disadvantage of organic fertilizer
Answers
Answer:
See below.
Explanation:
Organic fertilizer is more environmentally friendly and economical, but it comes at a different cost. These fertilizers are both harder to obtain and take more effort to formulate. Furthermore, these products are not created equally, meaning some of them may not work as well and have inconsistencies. Correspondingly, they are also lower in nutrients, meaning crops that rely on fertilizer will not grow as effectively and risk dying.

If I have 8 DNA nucleotides, how manyDNAbases do I have?How many base pairs? a. 4 bases 8 base pairs b. 8 bases 8 base pairs c.8 bases 4 base pairs. d. 4 bases 4 base pairs
Answers
If you have 8 DNA nucleotides then, you would have 8 bases 8 base pairs. In a DNA double helix, the nitrogenous bases on one strand pair with specific bases on the other strand
DNA is made up of nucleotides, which are the basic building blocks of DNA. Each nucleotide is made up of a sugar molecule, a phosphate group, and one of four types of nitrogenous bases: adenine (A), thymine (T), guanine (G), and cytosine (C). These bases are the "letters" of the genetic code, and the order in which they appear in the DNA sequence determines the genetic information.
When the two strands of a DNA double helix come together, the bases on one strand pair with specific bases on the other strand. Adenine (A) pairs with thymine (T) through two hydrogen bonds, and cytosine (C) pairs with guanine (G) through three hydrogen bonds. This is known as base pairing.
So, if you have 8 DNA nucleotides, you would have 8 bases (A, T, C, G) and 8 base pairs( A-T and C-G).

The correct answer is Option C. If 8 DNA nucleotides are present then there should be 8 DNA bases and 4 base pairs.
Nucleobases are those which are usually nitrogenous bases or often simply bases, are nitrogen-containing organic compounds that form nucleosides that in turn, are components of nucleotides. The 4 DNA bases are Adenine(A), Cytosine(C), Guanine(G), Thymine(T).
Nucleic acids consists of fundamental units called base pairs. They consists of two nucleobases bound to each other by hydrogen bonds.
Now nucleotides can be defined as organic molecules that consist of a nucleoside and phosphates. Therefore if we have 8 nucleotides then we will have the same number of DNA bases that is 8 DNA bases and will be half the number of bases of DNA that is 4 DNA base pairs.

A book is sliding along a desktop. Because the book is in motion, you know that the forces acting on the book are ______? What is the force acting against the book?
Answers
Answer:
Normal force, gravity and Friction.
Explanation:
The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table.

Answers
The plasma proteins are molecules that circulate in the bloodstream and have various important roles. They are responsible for transporting molecules throughout the body, maintaining osmotic pressure, and activating enzymes.
Most of the plasma proteins are produced by the liver and include albumin, immunoglobulins, and fibrinogen. The blank tube in a colorimetric assay is usually a reagent blank that contains all of the reagents of the assay, except for the sample being tested. This is done to ensure that any absorbance differences between samples are due to the sample and not from other components of the assay.

The statement "Replica plating uses media on which the mutant will not grow but the parental type will and is useful for identifying auxotrophs." is true.
Replica plating involves transferring colonies from one plate to another in order to identify mutants that require specific nutrients for growth. The technique is useful for identifying auxotrophs, which are mutants that cannot synthesize certain essential molecules and require them to be provided in the growth medium.
By using media on which the mutant will not grow but the parental type will, replica plating allows for the identification of these auxotrophic mutants.

Answers
The age range (include ±) during which the first adult (permanent) teeth erupt is 6 to 7 years old.
Why do teeth erupt?A child's tooth will usually start to loosen when their adult teeth grow beneath it. The adult tooth pushes the baby tooth out as it erupts. When the root of a tooth begins to break down, it becomes loose. As a result, it will simply fall out and be replaced by an adult tooth. The primary teeth are lost as the child grows, and they are replaced by the permanent teeth.
The roots of the primary teeth are resorbed by the body as the permanent teeth form, causing the primary teeth to loosen and ultimately fall out. The adult teeth then take their place. The first adult teeth to emerge are usually the molars.
The first adult teeth to erupt are the first molars, which are typically found in the back of the mouth. The second molars follow shortly after the first ones. The incisors and canines emerge in the front of the mouth after the molars. In conclusion, the age range (include ±) during which the first adult (permanent) teeth erupt is 6 to 7 years old.

Why do think predatory animals like owls are often threatened in habitats that have been exposed to those chemicals?
Answers
Answer:
At each higher level of consumption, the amount of toxin is magnified.
Explanation:
Those predators all eat smaller secondary consumers, and those secondary consumers eat the primary consumers, which a lot of the times are exposed to DDT. For example bugs are often the primary target for DDT, once those bugs are exposed to the DDT they carry it in/with them. When a fish eats the bug, that fish is now exposed to the DDT. When the fish is caught and eaten by an eagle that eagle and its young are now being exposed to DDT. The DDT might not effect the full grown eagle for its lifetime but it does effect its young.
Predatory animals like owls are often threatened in habitats that have a more complex chemical composition due to the biomagnification and bioaccumulation of toxic substances in their bodies.
What is biomagnification?There are producers, consumers ,and decomposers are present in the food chain. The food chain starts with the producers, such as terrestrial plants, phytoplankton, herbs, etc.
The producer makes the food by photosynthesis, and this food is taken by the consumer. From the primary consumer/ herbivore, the energy and nutrients pass to the secondary consumer, and then to the tertiary consumer. After the deaths of the producer and consumer, they are decomposed by the decomposer.
If in an ecosystem there are chemicals present, then the chemicals attach to the plants' leaves and are consumed by the herbivores. The carnivores feed on herbivores, and the toxic material present in the herbivores is passed down to the carnivores. As a result, the toxic chemicals in the carnivores accumulate over time. This is called biomagnification. The owl is a carnivore that feeds upon the insect, so the magnification is seen.
Hence, the owl is threatened due to biomagnification.

A box has 400 J of gravitational potential energy and weighs 100 N how many meters above the ground is it
Answers
Answer:
4 meters
Explanation:
The formula for gravitational potential energy is mgh, where m is the mass of the object in kilograms, g is the gravity, and h is the height in meters. You can use this to set up the following equation:
400=100 * h
h=4 meters
Hope this helps!
The gravitational potential energy is 400J of the box whose weight is 100N. Therefore, the height for which box is above the ground is 4 meters.
What is Gravitational Potential energy?
Gravitational potential energy is the energy which an object possesses because of its position above the ground level in a gravitational field such as the gravitational field of the Earth. The gravitational acceleration of the Earth can be assumed to be constant at about 9.8 m/s².
The gravitational potential energy can be calculated by the formula:
G.P.E = m × g × h
where, G.P.E = Gravitational Potential Energy,
m = mass of an object,
g = acceleration due to gravity = 9.8 m/s²,
h = height which the box attains
G.P.E = w × h (Since, w = m × g)
h = G.P.E. / w
h = 400J / 100N
h = 4 meters
Therefore, the height of the object is 4 meters.
