Which of the following is NOT a statement from the cell theory?
O All cells come from pre-existing cells.
•All cells require water for survival.
•All living things are composed of cells.
•Cells are the basic unit of structure and function of living things.
Answer:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Therefore, B is the answer.
"All living cells require water for survival" is NOT a statement from the cell theory.
All cells require water for survival is not a statement from the cell theory.
What is cell theory?The cell theory is a fundamental principle in biology that states that all living organisms are composed of one or more cells and that the cell is the basic unit of life. The theory was first proposed by German scientists Matthias Schleiden and Theodor Schwann in 1839, and later refined by Rudolf Virchow in 1855. The three main principles of the cell theory are:
All living organisms are composed of one or more cells.The cell is the basic unit of life and structure for all living organisms.All cells come from pre-existing cells through the process of cell division.The cell theory is considered one of the most important and enduring concepts in biology, and it forms the foundation for understanding the structure and function of cells and the organization of life on Earth.

SIDANT
Answer:
[tex]\boxed {\boxed {\sf D. \ During \ the \ time \ labeled \ D, \ when \ the \ temperature \ stays \ the \ same}}[/tex]
Explanation:
Phase changes have to happen at a specific temperature. During a phase change, the energy is used to make the change happen, instead of raising the temperature.
On a graph, a constant slope, or in this case temperature, is a flat line. On this graph, the flat lines are at B and D.
There is no answer including B, but there is for D.
Choice D: During the time labeled D, when the temperature stays the same is correct.
Why are animal gametes haploid?
a. Gametes have two copies of each chromosome
b. Gametes are developing embryos that develop into haploid adults
c. Gametes have one copy of each chromosome to create a haploid individual
d. Haploid egg and sperm cells combine to create a diploid individual
Answer:
d. Haploid egg and sperm cells combine to create a diploid individual
Explanation:
Animals are diploid organisms (2n) and undergo sexual reproduction. This sexual reproduction causes them to produce gametes via a process called MEIOSIS. Meiosis is a division that reduced the number of chromosomes in the daughter cell (gamete) by half.
This means that meiotic division produces haploid gametes (n) from a diploid animal. This happens so that when the haploid sperm cell (male gametes) and haploid egg cell (female gametes) meet in a process called FERTILIZATION, a diploid individual is created.
Answer:
D. Haploid egg and sperm cells combine to create a diploid individual
Explanation:
Which statements accurately describe animals? Check all that apply.
1. Animals are eukaryotes.
2. Animals are single celled.
3. Animals have cells with a nucleus and organelles.
4. Animals make their own food.
5. Animals are capable of sexual reproduction.
Answer:
Option One
Option Five
Option Three
Explanation:
It's not the second option because not all animals are single celled, some are actually multicellular. It's not the fourth option because animals don't make their food, some eat other animals and some eat plants. Leaving options one, five, and three because for one animals are eukaryotes which are organisms that consist of cells, option three because every cell has a nucleus and if organisms have cells they have a nucleus. Then five because animals are capable of sexual reproduction.

A,c,d is correct
Explanation:
If the frequency of the black allele for the moth coloration gene in newly founded island population of moths in genetic draft lab simulation was 78% what was the frequency of the white allele in that same population at the same time?
Answer:
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution.[1][2] In 1978 Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."
The dark-coloured or melanic form of the peppered moth (var. carbonaria) was not known before 1811. After field collection in 1848 from Manchester, an industrial city in England, the frequency of the variety was found to have increased drastically. By the end of the 19th century it almost completely outnumbered the original light-coloured type (var. typica), with a record of 98% in 1895.[5] The evolutionary importance of the moth was only speculated upon during Darwin's lifetime. It was 14 years after Darwin's death, in 1896, that J.W. Tutt presented it as a case of natural selection.[6] Due to this, the idea widely spread, and more people believed in Darwin's theory.
Bernard Kettlewell was the first to investigate the evolutionary mechanism behind peppered moth adaptation, between 1953 and 1956. He found that a light-coloured body was an effective camouflage in a clean environment, such as in Dorset, while the dark colour was beneficial in a polluted environment like in Birmingham. This selective survival was due to birds which easily caught dark moths on clean trees, and white moths on trees darkened with soot. The story, supported by Kettlewell's experiment, became the canonical example of Darwinian evolution and evidence for natural selection used in standard textbooks.[7]
However, failure to replicate the experiment and criticism of Kettlewell's methods by Theodore David Sargent in the late 1960s led to general skepticism. When Judith Hooper's Of Moths and Men was published in 2002, Kettlewell's story was more sternly attacked, accused of fraud, and became widely disregarded. The criticism became a major argument for creationists. Michael Majerus was the principal defender. His seven-year experiment beginning in 2001, the most elaborate of its kind in population biology, the results of which were published posthumously in 2012, vindicated Kettlewell's work in great detail. This restored peppered moth evolution as "the most direct evidence", and "one of the clearest and most easily understood examples of Darwinian evolution in action".

Compare and contrast serine proteases and aspartic proteases. Not all answers will be used. Serine protease Both Aspartic protease
Answer: The main similarity between the serine protease and aspartic protease is that these enzymes catalyze the break down or hydrolysis of the peptide bonds.
Explanation:
Serine protease structure has a triad of histidine, serine, and aspartic acid that are joined with the hydrogen bonds. Aspartic protease has a structure which includes the two aspartic acid residues which attack the peptide bond.
Serine protease catalyzes the hydrolysis of the peptide bonds with the the help of two tetrahedral intermediates, whereas the aspartic protease abstracts the proton from water molecule it results in nucleophilic attack on the carbonyl atom of carbon resulting in breakage of peptide bond.
Why are stem cells harvested from early embryos useful in medicine?
Answer: Cell therapies would use stem cells, or cells grown from stem cells, to replace or rejuvenate damaged tissue. Scientists also want to use stem cells to understand disease and find drugs that might treat it.
