An unidentified plant produces spores, has many cells, but does not have true leaves. What plant is it?

A. liverwort
В. fern
C. gymnosperm
D. angiosperm

Answers

Fern is the correct answer

An unidentified plant produces spores, has many cells, but does not have true leaves. It is a fern or the angiosperms. Thus, option C is correct.

What are angiosperms?

Angiosperms, that are also known as flowering plants, have “seeds” that are sealed off within an “ovary”, while gymnosperms do not have fruits or flowers and have uncovered seeds on the surface of leaves. Seeds of gymnosperms are often arranged as “cones”.

The features and characteristics that distinguish angiosperms from gymnosperms are fruits, flowers, and “endosperm” in the seeds. Examples of “Angiosperms” are “monocots” like orchids, lilies, agaves, grasses and dicots like, peas, roses, sunflowers, maples and oaks. “Gymnosperm” examples include “non-flowering evergreen” trees like pine, fir and spruce.

Therefore,An unidentified plant produces spores, has many cells, but does not have true leaves. It is a fern or the angiosperms. Thus, option C is correct.

An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.

Answers

Answer:

C.

Explanation:

thats just his first law of motion

Answer:

C. An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.

Explanation:

In essence, Newton's first law of motion states that an object at rest won't move unless an outside force causes it to move. Similarly, an object moving at a constant speed will continue moving at that same speed indefinitely, unless an outside force causes it to change speed.

Which of these is the direct result of an error in the transcription of a DNA nucleotide
Amino acids do not bond to tRNA.
The nuclear membrane is ruptured.
A codon sequence is incorrect.
Transportation of mRNA does not occur.

Answers

The direct result of an error in the transcription of a DNA nucleotide is that a codon sequence will be incorrect. So the correct option is C.

What is transcription?

The first step in the expression of a genetic code is called transcription. During gene expression, the information stored in the DNA is expressed in the form of proteins.

In transcription, DNA is utilized to produce RNA. The RNA molecule is the copy of the DNA's genetic sequence. The RNA copy produced by the process of transcription is called an RNA transcript.

This transcript has the required information for the construction of a polypeptide chain. But before the formation of proteins, a eukaryotic RNA transcript requires processing to be converted into mRNA.

The mRNA thus produced has codons for the formation of proteins. Each amino acid is a result of the translation of three codons.

Therefore, if there is an error in the transcription of DNA nucleotides, the codon sequence will be incorrect. The correct option is C.

Products enter a reaction and reactants come out of a reaction true or false?

Answers

Answer:

[tex]\boxed {\boxed {\sf False }}[/tex]

Explanation:

In a chemical reaction, the products are produced. The reactants are the substances that react.

In a chemical reaction equation (with the arrow pointing right) the reactants are on the left and the products on the right.

[tex]reactants \rightarrow products[/tex]

The reactants enter and the products come out.

So, the statement given - products enter a reaction and reactants come out - is false and it is actually the other way around.

Which of the following is true regarding glycolysis ?
Choose 1 answer.
A.) It requires glucose as a reactant.
B.) It produces 36 ATP.
C.) It occurs in the mitochondria.
D.) It is an aerobic process. ​

Answers

Answer:

I would have to say A

Explanation:

Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. So we already know that it uses glucose because thats what its breaking down. Glycosis produces 2 ATP so B is wrong. Glycolysis happens in the cytoplasm so C is wrong. Finnaly aerobic is using free oxygen in the process of the reaction. However glycolysis uses no oxygen and is  anaerobic.

Glycolysis requires glucose as a reactant.  

Glycolysis refers to a cytoplasmic pathway that dissociates glucose into the three-carbon compound and produces energy in the form of ATP.  

• The process of glycolysis takes place in the cytoplasm.  

• In the process, the net production of 2 ATPs takes place.  

• It can be both anaerobic and aerobic process.  

• The process of glycolysis completes in 10 steps, five of which are in the preparatory phase and the rest 5 are in the pay-off phase.  

• The process of glycolysis is used by all the cells of the body to produce energy, and the final product of glycolysis is pyruvate.  

Thus, correct answer is option A, that is, it requires glucose as a reactant.
