Answer:
The words that complete the sentences are:
- EUKARYOTIC
- MULTIPLE
- CIRCULAR
Explanation:
Replication is the process whereby genetic material is duplicated into two identical copies. It is a key process that must occur prior to any cellular division (mitosis or meiosis). However, DNA replication occurs slightly different in eukaryote and prokaryote.
- Eukaryotic cells are cells that possess a membrane bound nucleus to house their NUMEROUS/MULTIPLE LINEAR chromosomes. On the other hand, prokaryotic cells do not have a membrane bound nucleus to house their SINGLE CIRCULAR chromosome.
- Due to the fact that linear chromosomes of eukaryotes are multiple in number, their replication occurs in MULTIPLE LOCATIONS but that of prokaryotic cells take place in a SINGLE LOCATION.
The immune system protects the body against foreign substances and disease-causing organisms. The immune system is made up of many different types of special cells, tissues, and organs.
Which of the organs pictured above plays a major role in the immune system?
A.
gall bladder
B.
kidney
C.
spleen
D.
pancreas
The right response is C. spleen. The immune system heavily depends on the spleen. It is an organ that is in charge of filtering blood and getting rid of faulty red blood cells, and it is situated in the upper left part of the abdomen.
What are lymphocytes ?Lymphocytes are specialised immune cells found in the spleen that aid in the defence against infections and other foreign substances. White blood cells, which are crucial for fending off infections and illnesses, are also stored in the spleen.
The gall bladder, kidney, and pancreas are the other organs shown but have minor functions in the immune system. Bile is stored in the gall bladder and aids in the body's fat digestion.
The kidneys aid in filtering waste from the circulation and preserving equilibrium.of bodily liquids. Enzymes that are produced by the pancreas aid in the digestion of meals.
As a result of filtering blood, storing white blood cells, and creating specific immune cells to aid in the defence against illnesses and foreign substances, the spleen contributes significantly to the immune system. The gall bladder, kidney, and pancreas are the other organs shown but have minor functions in the immune system.

Plzz help will give brainiest. What pair of chromosomes do not go through crossover
Answer:
The Y chromosome do not go through crossover
Explanation:
Typically, genes from the mother and father are shuffled -- or, "cross over" -- to produce a genetic combination unique to each offspring. But the Y chromosome does not undergo crossing over, and, as a result, its genes tend to degenerate, while repetitive DNA sequences accumulate. Each chromosome is made up of DNA.
Answer:
it is the y chromosomes that do not go through crossover.

1. What are the three stages of the cellular respiration pathway, listed in the order in which they occur?
The three stages of the cellular respiration pathway are glycolysis, pyruvate oxidation, and the citric acid cycle.
What is cellular respiration?Food molecules are broken down into energy, water, and carbon dioxide during cellular respiration. In the presence of oxygen, cells respire. Multiple chemical cycles are involved in cell respiration. The Krebs cycle, phosphorylation cycle, and citric acid cycle are the cycles.
Glycolysis, the citric acid cycle, and the electron transport chain are three distinct metabolic pathways that come together to form cellular respiration. The process known as pyruvate oxidation is required in order to convert pyruvate molecules is a product.
Therefore, the citric acid cycle, pyruvate oxidation, and glycolysis are the three steps in the cellular respiration pathway.

2. What is a feature of transcription? * 1 point Both strands of a DNA molecule act as a template for mRNA. Nucleoside triphosphates become nucleotides by losing three phosphates. RNA polymerase binds to the promoter region. The sense strand acts as a template for mRNA.
Answer:
The correct answer is ''RNA polymerase binds to the promoter region. ''
Explanation:
The process of DNA transcription is the first step towards the formation of proteins from DNA. DNA transcription is the synthesis of mRNA (messenger RNA) from DNA that will later be translated to form proteins. RNA polymerase must recognize the starting point of synthesis. This area of DNA, described as a promoter, consists of two short sequences of bases located 10 and 35 base pairs from the initial point of synthesis. By convention, to describe the region of DNA where the gene to be transcribed is located, the number +1 is given to the base pair (DNA) where RNA synthesis begins, up to + n, which will be the last base pair where synthesis ends. RNA polymerase is the enzyme that transcribes the sense strand of DNA into a messenger RNA molecule. This enzyme forms the phosphodiester bond in growing RNA by nucleophilic attack on the incoming nucleotide. It does not need a primer and synthesizes in the 5′-3 ′ direction.

In a pedigree, what is a carrier?
A - A person who has the trait.
B - A person who carries the gene for a trait, but doesn't display it.
C - A person who carries the gene for the trait and does display it.
Answer:
C
Explanation:
Pedigrees can show someone is a carrier for diseases by determining which parent, if not both, is either dominant or recessive. Each child must have a letter from their parent then that will determine if someone gets a disease or not then it goes on from generation to generation.
Answer:
the answer is C
Explanation:
A hereditary carrier (genetic carrier or just carrier), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but usually does not display that trait or show symptoms of the disease.
If one or none of the parents has the trait and it skips a generation, then the pedigree is...
A .Dominant
B. Recessive
C. Sex-Linked
Explanation:
your answer is recessive recessive usually Skips a generation .
Seeds can be dispersed through human beings and animals. Explain
Answer:
When animals take fruits or seeds for food, they act as willing transporters of the plant's seeds. Animals can disperse seeds by excreting or burying them

Explanation:
Answer:Some fruits,like cocklebur,have books or sticky structures and stick to an Animal's fur.
Explanation:
Humans also play a role as disperse by moving fruits to new to new places and discarding the inedible portions containing Seeds.
