in which Domain & Kingdom would scientists classify an organism, whose cells contain a nucleus, has cell walls made of chitin, and does not have chloroplasts?

Answers

Answer:

The correct answer is -

Domain: eukarya

kingdom: fungi

Explanation:

A cell with a nucleus and cell wall made up of the chitin and does not have chloroplast, are all the characteristic features of an organism of kingdom fungi which is a group of eukaryotic organisms.

The cells with the nucleus are grouped in the domain eukarya while the prokaryotic organism does not carry a nucleus in their cell and divided into Archaea and bacteria. The chitinous cell wall without any chloroplast in the cell is one of determining features of the fungi kingdom.

Question 1/7 The Nile River carries sediments to the ocean. Over time, the sediments are compressed as more sediments are deposited on top of them. Which type of rock will be formed?​

Answers

Answer:

Sedimentary Rock

Explanation:

Sedimentary rocks are formed from pieces of sediments or other existing organic matter or rock.

The sedimentary rock formation process begins with weathering which involves the breakdown of the sediments into small fragments. The next process is erosion, where water like the Nile River carries them to other places -  in this case, the Ocean.

Over time, the sediments settle and become compressed as more sediments are deposited on top of them.

This leads to the formation of Sedimentary Rocks.

how does cell division help in growth and development of somatic cells and in gamete formation?

Answers

════════ ∘◦❁◦∘ ════════

[tex] \mathbb{CELL\:DIVISION\:(MITOSIS)} [/tex]

════════════════════

Well, im not sure what somatic cell is. But, the reason why cell division help in growth and development is because the main goal of cell division is to make more cells right? This is also why we keep growing (like taller/bigger) because more cells in our body because of that cell division.

#see pic of how cells in our body divide during mitosis

#sorry i borrow this ans for my latex experiment :v

════════════════════

Mitosis occurs in somatic cells this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

Some scientists seek answers in the depths of the sea. When Georg Steinhauser wanted answers, he looked within himself. Well, he looked within his bellybutton to be exact. The Austrian chemist spent three years researching the contents of his navel and the navels of others. He has solved one of life's greatest mysteries. We now know exactly what bellybutton lint contains!Steinhauser presented his findings in the online version of the journal Medical Hypotheses. The Vienna University scientist analyzed over 500 samples to determine the exact makeup of the lint. As suspected, most of the lint was made up of cotton from clothing. The fabric pieces are not alone, though. Steinhauser found that the average bellybutton also contained pieces of dead skin, sweat, dust, and fat.Steinhauser's notes also explained how lint accumulates. Stomach hairs tend to grow in a circular pattern around the bellybutton. The hairs act like small hooks, capturing and holding contents within. Shaving stomach hair can lead to a lint-free bellybutton, but don't act too hastily. Although the contents of your navel may be a nuisance, research suggests that lint has a purpose. It is nature's way of protecting your bellybutton from germs and unwanted objects. I REALLY NEED THIS! SOMEONE PLEASE HELP!
