Consider the nest to be (0,0)
The bird first flew 40 km (20x2) up and then 45km (15x3) left
So the final coordinates would be (40, -45)

Ulleksa [173]

Answer:

smooth endoplasmic reticulum

Explanation:

Smooth endoplasmic reticulum differs from the rough endoplasmic reticulum in not having ribosomes on its surface. The smooth endoplasmic reticulum (SER) extends from the rough ER and forms a network of membrane tubules. The function of the smooth ER is to serve as a site for the synthesis of lipids, fatty acids, and steroids such as estrogens and testosterone.

Enzymes for the synthesis of these diverse biomolecules are present in smooth ER. The smooth ER present in the muscle cells is called the sarcoplasmic reticulum. It stores the calcium ions which are released into the sarcoplasm of muscle cells during muscle contraction.

Intermediate photographs should show the relation of evidence to other parts of the crime scene. A. True B. False​
hichkok12 [17]

Answer:

True.

Explanation:

<em>"adjective </em>

<em>adjective: intermediate </em>

<em>coming between two things in time, place, order, character, etc."</em>

Pictures correlating to the crime scene are like puzzles to find out the other meanings or cause of another picture.

For example:

A opened jug of milk sits on a table.

There's a blurred figure of a hand hitting the jug.

The jug is now laying on the table, dripping everywhere.

-

If we take out the middle picture "There's a blurred figure of a hand hitting the jug.", then we would not know what hit it over. Did someone bump into the table? Did a cat climb onto the table and release its almighty strength onto it? All we would know that it was once standing upright.

TLDR; Without intermediate pictures, it would be hard to grasp what happened on the scene. Intermediate pictures all have something in common with each other to help interpret what occurred to the viewer.

lawyer [7]

Answer:

The age of the cell

Explanation:

Assuming your question was meant to be "Which of the following is NOT a difference between Prokaryotic and Eukaryotic cells?", everything except the age is different.

Prokaryotes are simple cells that have no nucleus and are generally small. Eukaryotes are complex cells that have a nucleus, organelles, and are much bigger than prokaryotes.

What are histones, and how are they arranged in nucleosomes? Drag the terms on the left to the appropriate blanks on the right t
Eva8 [605]

Answer:

1) c. five

2) a. lysine and arginine

3) g. two

4) d. four

Explanation:

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 then condense it to chromatin.

Histones include five main classes of relatively small basic proteins containing relatively large amounts of lysine and arginine. Nucleosomes are made of two each of four types of histones.
