Explanation:
please mark me brainliest
DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand. Therefore, it is true.
What is DNA replication?The process of duplicating the parent DNA helix into two identical daughter helices is known as DNA replication. One parent strand is passed down to each daughter strand in this semi-conservative procedure.
In prokaryotic cells, DNA replication takes place in the nucleoid area, whereas it happens in the nucleus in eukaryotic cells. Prior to cell division, DNA replication takes place in the S phase of the cell cycle.
Replication fork pairs that form at the origins of replication and then move in opposition to one another carryout genome duplication. When convergent replication forks meet, DNA replication is complete. Hence, it is true.

In otters, the allele for brown fur (B) is dominant over the allele for silver fur (b). Two brown otters mated and a silver pup (baby otter) was born. What were the genotypes of the parents?
Answer:
Bb, Bb
Explanation:
since silver was recessive, both parents had to carry the gene to affect the nest generation but since they were both brown they also needed to have the brown gene present.
The genotype of the parents who produce a silver pup will be heterozygous dominant i.e., Bb. The ratio of the offspring produced from this cross will be 3:1.
What is Genotype?
The genotype of an organism is the complete set of genetic material which is present in the nucleus of the cell. Genotype can also be used to refer to the alleles an individual carries in a particular gene or genetic location in the genome.
In otters, the allele for brown fur (B) is dominant over the allele for silver fur (b). When the two brown fur otters were mated, a silver pup was born.
In this case, brown fur phenotype can be expressed in two cases, homozygous (BB) and heterozygous (Bb).
When both the parents are heterozygous for the character i.e., Bb. Then, the offspring produced will be in the phenotypic ratio of 3:1 i.e., three offspring will have brown fur and one will have silver fur.

2. food bolts chyme
DIFFERENCES
the substance which The semi hard the soup like substance
is eaten by a person. substance
it is semi digested in it leaves oral cavity it leaves stomach and went to
oral cavity. and move to stomach small intestine
SIMILARITIES
They all are nutrients containing meterials which are to be digested. they all contain carbohydrates,protiens ,fats and vitamins (somehow if the food is taken from plant source) and they all are about to be absorbed.
3.DIGESTIVE SYSTEM:
the process in which food substance is broken into pieces and is converted into the simpler substances which can be assimilate by body cells. Different glands scretes digestive juices which digest fats,protiens ,carbohydrates etc e.g gastrin,bile,pancreatic juice and intestinal juice. and at the end all the product remain is excreted out after assimilation.
ORGANS INVOLVED: oral cavity,oesophagous,stomach small intestine ,large intestine.
4. salivary glands are damaged:
if salivary glands are destroyed or damaged then no saliva will produce to protect the walls of gut and the gut walls will be damaged by the acidic or basic juices of gut which will causes severe ulcer of oesophagous, stomach or intestinal.
5.CONSTIPATION:
when too much water is absorbed by the walls of large intestine so the end product which is to be excreted will become so hard that it is dificult to excrete 0it out of body.
CAUSES: it may be caused by hormonal disturbance ,water deficiency and may be by silliness of a person that he use to be silly to go to the bathroom at time.
6. INGESTION: Taking of food from the outside of the body from different means which contain nutrients essential for body growth.
DIGESTION: Breakdown of food into simpler substance which can be easily taken by body cells .
ABSORPTION:Large intestine and smaal intestine absorbs the certain amount of nutrients and water from the digested substance to fullfil the body deficiencies. These nutrients are then assimilated into the body.
EXCETION:the substance which remain after absorption is excreted out of the body from exterior opening called anus is called excretion.

what is energy releasing equation ?
Answer:
I hope this helps you
Explanation:
ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.
The energy releasing equation, also called enthalpy is calculated using the formula: ΔH = Hfinal - Hinitial
What is enthalpy?Enthalpy refers to the heat content of a system combining the energy of the system with the product of its pressure and volume. When a chemical reaction or physical process occurs energy is emitted in the form of heat.
The equation used to determine the amount of heat released by a system during a reaction or physical process is known as the energy release equation.

What are the possible blood types of a baby with a mom who is heterozygous for blood type A and a dad with type O?
Answer:
A & O group
Explanation:
Dad will be having io io allele and mom will be having ia io
The possible blood types for the baby are either A or O, with equal likelihood of 50% for each.
What is blood type?A classification system called blood type explains whether or not specific antigens are present on the surface of red blood cells. Each of the four major blood types—A, B, AB, and O—has distinct antigen markers.
A and O are the two possible blood types for a child whose mother is heterozygous for blood type A (genotype AO) and whose father has type O (genotype OO).
A baby has a 50% chance of acquiring the A allele from the mother and a 50% chance of inheriting the O allele from the father because each parent gives one of their two blood type genes to their offspring.
Baby with blood type A inherits the A allele from the mother and the O allele from the father (genotype AO).
The child will have blood type O if both parents carry the O allele (genotype OO).
Therefore, the possible blood types for the baby are either A or O, with equal likelihood of 50% for each.

If a DNA strand has 32 % guanine before semi conservative replication occurs, what
percent thymine will each new strand have after replication?
Answer:I believe that the answer would be 18
Explanation:
32 divided by 2 is 18
If a DNA strand has 32% Guanine before semi-conservative replication occurs, then the percent Thymine will each new strand have after replication will be 18%.
The deoxyribonucleic acid (DNA) is a double helix molecule composed of four types of nucleotides: Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).In DNA, Adenine (A) always pairs with Thymine (T), whereas Cytosine (C) always pairs with Guanine (G). The replication of DNA is semi-conservative because after replication each DNA molecule contains one original DNA strand and one newly-synthesized DNA strand.If a DNA molecule contains 32% of Guanine, then the content of G + C is equal to 64%, so the content of T + A is equal to 36% (64 + 36 = 100) and T content is 18% (18 + 18 = 36).In conclusion, if a DNA strand has 32% of Guanine before replication, then the percent of Thymine after replication will be 18%.

The trend shows that the Enzyme Pepsin is active and prefers the pH level of 2. While Trypsin Is much active at pH 8 and prefers that pH level.
Explanation:
You can tell by seeing the enzyme activity compared to the pH range. Enzymes are simply proteins which work around your body so pepsin since it is active in acidic levels (pH 2) is probably an enzyme found in the stomach.
The trend shows that the Enzyme Pep sin is active and prefers the pH level of 2. While Trypsin Is much active at pH 8 and prefers that pH level.
What are the functions of enzyme pepsin?Pepsin is an endo peptidase that breaks down proteins into smaller peptides. It is produced in the gastric cells of the stomach lining and is one of the main digestive enzymes in the digestive systems.
Pep sin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pep sin as an in active zymogen called pepsinogen.
In the digestive tract pepsin effects only partial degradation of proteins into smaller units called peptides, which then either are absorbed from the intestine into the bloodstream.

What do you mean by cell division?Cell division is the process by which a parent cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.
