Answer 1
Answer:

The excretory system is responsible for removing all of the following from the body excep t

A. Toxic Waste B. Gaseous Waste C. Dissolved molecules D. Cells

Answer:

D. Cells

Explanation:

The excretory system consists of organs that help the body to get rid of excess and waste materials from the body, and also helps in maintaining internal homeostasis in the body. These organs include the large intestine, skin, lungs, kidneys. Most of the wastes are products of metabolism. These waste materials that are no longer useful to the body could be in liquid or gaseous form. Examples of substances removed from the body by the excretory system are urine, feces, sweat etc.

Cells are not part of the substances removed by the excretory system.

The portion of the DNA molecule that can vary is its(A) sugar.
(B) base.
(C) deoxyribose.
(D) ribose.
(E) phosphate

Answers

Its' base can vary. The sugar (deoxyribose) stays the same. And the phosphate also stays the same. There are four different bases. The arrangement of the bases in threes are called condons. These code for amino acids. These make proteins which make us what we are. The codes are also called genes.

In grafting, the plant with the root system is called the scion rootstock cutting, and the portion of the plant with the buds is called the rootstock scion cutting.

Answers

In grafting, the plant with desired root system is called the rootstock, and the portion of the plant with the buds is called the scion.

The grafting is a horticultural technique in which parts from two or more plants are joined together to grow as a one single plant.
Rootstock is the plant selected for its roots because it can provide different properties, such as fruit size, or because it is resistant to drought or diseases. 
Scion is the plant selected for its leaves, flowers, fruits or stems.

A scientific model is easier to interpret and understand when it includes the main parts or processes, rather than every detail of every part or process. is this true or false

Answers

This is true, because extra detail and collateral information begets you to digress and eventually lead some people astray because they lose interest. You'd rather be straight to the point and give key facts about your model instead.

A codon is made up ofA. a two-nucleotide sequence.
B. a three-nucleotide sequence.
C. a four-nucleotide sequence.
D. a five-nucleotide sequence.

Answers

A three nucleotide sequence. On mRNA, once it enters the ribosomes codons, ie AGU (adenine, guanine and uracil) is a codon, and is then paired with an anticodon of complementary bases which create a link of amino acids to create a protein.
The first path is fromthe nucleus. DNA from the nucleus, assigns specific job for the organelles tofollow through mRNA. The mRNA goes out from the nucleus and enters thecytoplasm where ribosomes will attach to the mRNA. The ribosome-mRNAcombination binds to the endoplasmic reticulum and signals the tRNA to translatethe message from DNA. The rRNA contains codons that will be used for the translationof the messages by the tRNA. These codons has a three – nucleotide sequence. Avesicle that contains the enzyme grows out from the endoplasmc reticulum anstransport the enzyme to the Golgi body for further processing. The answer isletter B.

Which of the following are not true of exocytosis? A.it occurs at the cell membrane B.it does not require energy C.it needs a vesicle to move the matter D.it expells matter out of the cell

Answers

The statement which is not true is it needs a vesicle to move the matter. Thus, option C is correct.

What is cell?

Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.

Basically,cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.

The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.

Therefore,The statement which is not true is it needs a vesicle to move the matter. Thus, option C is correct.

perfect cosmological

Answers

The correct answer is Option C

The theory of perfect cosmology states the the whole universe is homogeneous and it is isotropic in the space and time. This is the reason the space looks the same everywhere. The space looks the same as it was and will look the same always. This theory works on the principle of steady state theory and emerges.
