Arrange these groups in order from most inclusive (most general) to least inclusive (most specific).
LUCKY_DIMON [66]

These groups are arranged in order from most inclusive (most general) to least inclusive (most specific) is gnathostomes, osteichthyans, lobe-fins, tetrapods, amphibians.

<h3>What is gnathostomes?</h3>

The jawed vertebrates are called gnathostomata. The phrase comes from the Greek words "jaw" and "mouth." Approximately 60,000 species make up the diversity of the gnathostome, which represents 99% of all vertebrates still alive today.

<h3>What is osteichthyans?</h3>

A broad taxonomic group of fish called osteichthyes, also known as the "bony fish," has skeletons that are predominantly made of bone tissue.

<h3>What is lobe-fins?</h3>

The taxon Sarcopterygii, also known as Crossopterygii, is made up of bony fishes noted for having lobe-finned fishes as its members.

<h3>What is tetrapods?</h3>

Four-legged vertebrates that make up the superclass Tetrapoda are known as tetrapods, which derives from the Ancient Greek (tetra-) "four" and "foot." It consists of synapsids, dinosaurs, and extinct as well as living amphibians, reptiles, and dinosaur-related birds (including mammals).

¿Qué moléculas conforman las cadenas de nucleótidos?
yaroslaw [1]

Answer:

English:

RNA and DNA are polymers made up of long chains of nucleotides . A nucleotide is made up of a sugar molecule (ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).

Spanish:

El ARN y el ADN son polímeros formados por largas cadenas de nucleótidos. Un nucleótido está formado por una molécula de azúcar (ribosa en el ARN o desoxirribosa en el ADN) unido a un grupo fosfato y una base nitrogenada. Las bases utilizadas en el ADN son la adenina (A), citosina (C), guanina (G) y timina (T).

In plants and microorganisms, amino acid biosynthesis is a matter of synthesizing the appropriate ____ followed by transaminatio
Stella [2.4K]

Answer:

α-ketoacid; glutamate.

Explanation:

The amino acid synthesis is important for all the living organism. Different organism uses different strategy for the synthesis of amino acid.

The α-ketoacid is generally used in the synthesis of amino acid especially in microorganisms and plants. The transamination of glutamate results results in the formation of particular alpha-keto acid.

Thus, the correct answer is option (b).

Imagine you are the nucleus of a plant or animal cell and have been asked to mentor an organelle that is new to the cell. Take y
Ivan

Hi,

I am Nucleus of the cell. I am the most important part of the cell and i have genetic material that is transferred to the offspring upon reproduction. I also supervise many important processes of cell like synthesis of proteins.

I will take you on the trip of our whole cell where you will be able to meet different organelles and know a little about their roles in cell. Let us meet them one by one:

1) Nucleolus: It is a darkish and roundish structure that resides inside me. Its role is in the synthesis of an important type of RNA called ribosomal RNA.

2) Nuclear membrane: This membrane surrounds me and is contains small pores for the movement of ribosomal RNA and proteins. Due to this surrounding DNA stays inside me and donot leaves me.

3) Golgi Complex: This is like a packaging and storing organelle of cell that processes and packs the proteins and exports them outsise or inside the cell. Their secretions include digestive glands, saliva, oils etc.

4) Rough Endoplasmic Reticulum: It consists of several long canals that form a series running throughout the cell and contains ribosomes attached with them. They are the organelles which transport proteins to the golgi complex for their packaging.  

5) Smooth Endoplasmic Reticulum: It has an important role in the detoxification process converting toxic substances into less toxic forms. They are in structure similar to rough endoplasmic reticulum except that they donot have ribosomes attached to them.

6: Centrioles: They are important in the process of cell division and are present in animal cells only.

7:Mitochondria: This is called as power house of the cell because all the processes that convert food into energy take place in this part. You can see it has two membranes outer is smototh while inner forms foldings.

8: Ribosomes and Free Ribosomes- They are freely floating in the cell or attached with endoplasmic reticulum, They have role in protein synthesis.

9: Lysosomes: They have an important function because they remove worn out and old organelles by digesting them. Therefore, they contain good digestive enzymes.

Hope it helps!

One of your fellow systematists has asked you to help her group organisms into a valid phylogenetic tree. At present, she has gr
kipiarov [429]

Answer and explanation:

Monophyletic species are the species whose lineage belongs to the common recent phylogenetic ancestor. As mentioned in the question, the girl has 3 species namely G, H, and K. Because there is no other criteria given, we assume that the closeness of alphabets would reflect the closeness of species. Thus, G and H are closer relative than K. Therefore, if she adds <u>I, and J species</u> in the list, all of them will be closer relatives and we can say that they are monophyletic now.
