All cells are produced from existing cells statement is a part of the cell theory.
What is cell theory?In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
A component of the cell theory is that all living things are composed of one or more cells. A component of the cell theory is that the cell is the basic unit of life. A component of the cell theory is that all new cells arise from existing cells.
All known living things are made up of cells. The cell is structural & functional unit of all living things. All cells come from pre-existing cells by division.

ATGCCATGGCATTGA --> ATGCCATGCATTGA
Answer:
Deletion
Explanation:
ATGCCATGGCATTGA
-->
ATGCCATGCATTGA
Comparing the two sequences, you can see that one G nucleotide is missing in the new sequence compared to the original.
This is a single nucleotide deletion, where one nucleotide is lost from the sequence. Otherwise, the sequence is entirely unchanged.
What did Gould and Eldridge infer about the pace and timing of evolutionary change? (5 points)
a
Evolutionary change occurred gradually and constantly throughout time.
b
The pace of evolutionary change has slowed down over time and it only rarely occurs now.
c
Periods during which evolution occurred were always preceded by a catastrophe.
d
Long periods of stability were punctuated with periods of evolutionary change.
Answer:
d. Long periods of stability were punctuated with periods of evolutionary change.
Explanation:
Gould and Eldridge inferred that evolution occurred because of the sudden existence of new factors that force a certain type of species to adapt to the new situation. (Things such as sudden change in the environment, sudden change of the species' genetic composition that passed over during natural selection ,etc)
They believe this is why periods of evolutionary change happened in considerably shorter period of time right in the middle of periods of stability.
The answer is D.
Explanation:
Long periods of stability were punctuated with periods of evolutionary change.

Explanation:

Transfer RNA acts as a link (also called an adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that comprise a protein. Therefore, option (C) is correct.
What is the function of tRNA?Transfer RNA is an adapter molecule that is made of RNA and normally ranges in length from 76 to 90 nucleotides. Its primary function is to act as the physical link between the amino acid sequence of proteins and the mRNA that encodes them. Transfer RNA achieves this goal by transporting an amino acid to the ribosome, which is the component of a cell that is responsible for the synthesis of proteins.
The tRNA molecule is characterized by its characteristic folded structure, which consists of three hairpin loops that are arranged in the manner of a clover with three leaves. A sequence known as the anticodon is contained within one of these hairpin loops. This anticodon has the ability to detect and decode mRNA codons. Each transfer RNA (tRNA) has the amino acid that corresponds to it connected to the very end of it.

Answer:

Explanation:
I just took the test 100 percent, you can trust me.
In A Quiz Competition, You Are Asked A Question Where You Have To Choose The Statement Which Is/ Are Incorrect? (1 Point) [A]. Squamous epithelium is made up of thin, flat, irregular shaped cells which fit together like floor tiles to form a compact tissue. [B]. The cuboidal epithelium is found in kidney tubules, thyroid vesicles and in glands. [C]. The main function of columnar epithelium includes absorption and secretion. [D]. None of the above
Answer:
[D]. None of the above
Explanation:
Epithelium are one of the type of four tissues found in living systems. They possess a variety of functions and are found to line/cover the surfaces of most organs. Epithelial tissues are classified based on the number of cell layers (simple and stratified) and shape (squamous, columnar, and cuboidal).
Based on their shape;
- Squamous epithelium are made up of scale-like flat cells that line the surfaces of alveoli of the lungs etc. They are of thin, flat, irregular shaped cells which fit together like floor tiles to form a compact tissue as stated in this question.
- Cuboidal epithelium contains cells whose shape are similar to that of a cuboid i.e. close width and height. They are located in the kidney tubules, thyroid vesicles and in glands like pancreas.
- Columnar epithelium are relatively thin and elongated in shape, hence, they are found in organs and surfaces whose function mainly is absorption and secretion.
Hence, NONE of the mentioned statements are UNTRUE

What do you think of dystopian societies?
Answer:
I am assuming you want my personal opinion.
theyre quite terrifying to think about. Like the fall of humanity is scary. to think the offspring i have created or the people i have known have gone from decent people to incredibly corrupt. In "1984" by george orwell, the dystopian society he has created horrfies me. The idea that even your thoughts are monitered disrupts your self expression and how you interact with the world. To live in a world where you cannot do anything but basic busy work seems tactful. I bvelieve people should be happy and never fear a hugher authority or a "system". Dystopian societies are exciting to read about but to really think deeply and complexly about them is horrifying.

Why can’t two pyrimidines be paired with one anothr ?
Answer:
There are two reasons for this. The first reason is that the distance between the two strands of DNA is constant. Two purines together would be too big to fit in that distance, and two pyrimidines together would be too small. The second reason is that the bonding between purines and pyrimidines is very specific.

Explanation:
Padma is having a baby. The best description of how her body will keep her in the homeostasis is a positive feedback mechanism increases the release of oxytocin to promote further contractions. Thus, the correct option is A.
What is the effect of oxytocin?Oxytocin is a natural hormone which manages the key aspects of the female and male reproductive systems in humans, including the labor, delivery, and lactation in females, as well as other aspects of the human behavior.
Oxytocin can induce the anti-stress-like effects such as reduction of the blood pressure and cortisol levels in humans. Oxytocin increases pain thresholds, exerts an anxiolytic-like effect and also stimulates various types of positive social interactions in individuals. In addition, it is also responsible for promoting growth and healing process.
Therefore, the correct option is A.
