The benefit of using a model is that : ( B ) provides a visual guide for abstract concepts

<h3>Definition of model</h3>

Models helps with the visualization of concepts or objects which cannot be easily seen or felt, It helps with the communication of ideas and predictions by scientists. Models represents abstract concepts which cannot be explicitly explained without the aid of a model.

Hence we can conclude that the benefit of using a model is that it provides a visual guide for abstract concepts.

14. natural selection; genetic drift

15. genetic makeup

16. a meerkat protects the offspring of its sister from an attack by hawks

17. the species will become extinct since it cannot adapt to the changes fast enough

18. the population must have genetic variation that leads to differential survival and reproduction

19. medium ground finches with small beaks survived multiple droughts.

Typically, acetylation of histone tails leads to ________. Typically, acetylation of histone tails leads to ________. relaxed pa

Answer:

relaxed packaging of the chromatin and increased transcription.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.

Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

#1. Which of the following structures would you expect to find in a single-celled organism? A. internal organs B. legs and feet

qwelly [4]

1. outer covering - none of the other answers can occur due to the absorbed solutions inability to reach the centre of the organism, smaller cells in greater numbers are more efficient as they can group together yet all absorb the right amounts of nutrients for its need. multi cellular organisms, such as humans can have the other answers in them as cells group together to make skin, muscles and organs. it also gives the organism to grow larger.

2. bacteria are single celled. bacteria reproduce through mitosis (cell division). bacteria break down decaying matter to obtain energy. every organism requires energy to live. Bacteria can move in order to reach their nutrient source.

The data table above includes the distance each planet is from the sun. Students in an Earth science class were asked to explain

Serga [27]

Student 4

Explanation:

The sun has less gravitational pull on Neptune because it is farther away. Gravity is the force by which a planet or other body draws objects towards its center.
Gravity keeps all the planets in its position and allows it to move in its orbit.
The force of gravity is inversely proportional to the distance between two objects.

So when the distance increases, the force weakens. Since Neptune approximately 4.8 billion kilometers away from the sun, its gravitational force is very less.
