The correct answer is C. -Cardiovascular System, -Digestive System, -Respiratory System.
These three body systems work together to provide the body with the necessary nutrients and oxygen, as well as to remove waste products. Here's how they function in a coordinated manner:
- The Digestive System breaks down food into nutrients that the body can absorb. It processes the food we eat into energy and basic nutrients, which are then absorbed into the bloodstream.
- The Cardiovascular System transports the nutrients absorbed by the digestive system to all the cells in the body. It also carries oxygen from the lungs to the cells and removes carbon dioxide and other waste products from the cells to be expelled from the body.
- The Respiratory System works closely with the cardiovascular system to oxygenate the blood. It brings oxygen into the body and removes carbon dioxide when we exhale. The oxygen is then picked up by the red blood cells and transported by the cardiovascular system to the tissues.
Together, these systems ensure that the body's cells receive the oxygen and nutrients they need to function and that waste products are removed efficiently. The other options listed do not represent systems with as closely related functions as the cardiovascular, digestive, and respiratory systems.

What the central idea of against all odds Earths fragile pioneers
Answer:
The central idea of "Against all odds: Earths fragile pioneers" is how Hawaii which is the most isolated island group on earth slowly was colonized by plants and animals.
Explanation:
Despite Hawaii's seclusion from the world, life got there through three means: wind,wings and water.Insects and seeds travel on birds that migrate or flee storms.Jet stream causes wind to move from Asia to Hawaii carrying seeds.And sometimes insects like cricket, and various seeds like hala reached Hawaii floating on the ocean.All these organisms faced harsh conditions, adapted and and now colonize Hawaii.Answer:
he Hala seeds can float in the ocean for so long because they have a blanket of spongy material, which help is Hala seeds float. I know this because in the text it says “How do its seeds survive the salty ocean? They are snuggled in a blanket of spongy material, which can float in the sea for months or even years. A species of Hawaiian crickets rafted in on pieces of floating wood. This supports the central idea because it shows how difficult it is for the colonize to get to Hawaii.

how are genes expressed for a particular trait.
Answer:
how are genes expressed for a particular trait?
Genes are expressed in two ways which could be either genotype or phenotype
genotype reflects the dominancy or recessives of a particular trait over another while phenotype entails the physical expression of such trait which could be height, color of skin among others
e.g
If P is purple while p is white
PP x Pp= PP, Pp, PP. Pp these are the genotype produced from the crossing of two parents which results into 2 homozygous gene and 2 heterozygous gene without any recessive gene
while the phenotype shows that all the offspring are Purple
Explanation:
Asthma is a condition in which a person’s airway becomes inflamed and produces extra mucus. One of the symptoms of an asthma attack is hyperventilation, or rapid breathing. Review the image and explain why asthma would cause this symptom.
the reason why asthma could cause this symptom is because the asthmatic bronchiole is much narrower than the normal bronchiole, and it's filled with mucus. If there isnt a sufficient amount of air getting through the lungs for gas exchange, the person will need to have heavier breaths to compensate.
Answer:
The asthmatic bronchiole is much narrower than the normal bronchiole, and it’s filled with mucus. If enough air does not get to the lungs for gas exchange, the person will need to breathe heavily to compensate.

which is the best procedure of separating a mixture of maize bean and sugar
Answer:
here are several methods of separating mixtures. The common ones are:
1. Winnowing
The wind is used to separate wharves (chaff), small sticks, and dry leaves, from grains or seeds by blowing the chaff away.
Chaff is usually lighter than the grains.2. Sieving
a sieve is used to separate mixtures of particles of different sizes. For example stones from flour.
The larger particles remain on the sieve while the finer ones pass through.
3. Picking
Here the large particles are separated from smaller ones by observing them and using the hands to remove the unwanted ones.
For example, stones are separated from rice or beans in this way.
4. Filtering
This method is used to separate a liquid from particles that cannot dissolve in it.
For example, separating sand from water using filter paper or piece of cloth.5. Decanting
This is when a liquid is separated from large particles of solids by pouring the liquid out gently.
For example, pouring off kerosene that has mixed with tiny ball bearings.
Explanation:
The best procedure for separating a mixture of maize, bean, and sugar involves physical and chemical separation techniques such as hand picking, sieving, magnetism, dissolving, filtering, evaporating, and density gradient.
Explanation:The best procedure for separating a mixture of maize, bean, and sugar is using a combination of physical and chemical separation techniques. Here is a step-by-step process:
Separate the large particles by hand picking or using a sieve to remove any visible pieces of maize, bean, and sugar. Use a magnet to separate any iron filings that may be present in the mixture. Add water to the mixture to dissolve the sugar. The sugar will separate from the maize and bean. Filter the mixture to remove the liquid portion, which will contain the dissolved sugar. Evaporate the water from the filtrate to obtain pure sugar crystals. Separately, use a density gradient technique to separate the maize particles from the bean particles. The maize will settle at the bottom, while the bean will float on top. Remove the floating bean particles and collect the settled maize particles.

For plants and other organisms to develop differences among their respective species the alleles of their genes must contain variations. What is the original source of these variations?
A) Mutation
B) Crossing over
C) Random fertilization
D) Independent assortment
A) Mutation is the original source of variations for plants and other organisms which develops differences among their respective species
Explanation:
Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.
A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.
Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.

Answer:
fungus
Explanation:
Among the options provided, a fungus is the decomposer.
In nature, decomposers play a critical role in recycling nutrients. They break down the remains of dead organisms and organic waste. Among the given options:
A whale is not a decomposer; it is a consumer.A dog is also not a decomposer; it is another type of consumer.A vulture is a scavenger, not a decomposer. While it eats dead organisms, it does not break down organic matter into simpler molecules.A fungus, however, is a true decomposer. It secretes digestive enzymes to break down dead organic matter externally, allowing it to absorb nutrients. For example, fungi can decompose tough materials like wood fibers, recycling nutrients back into the ecosystem.Therefore, the correct answer is fungus.

definition of binomial nomenclature
Answer:
the system of nomenclature in which two terms are used to denote a species of living organism, the first one indicating the genus and the second the specific epithet.
Explanation:
Final answer:
Binomial nomenclature is a system of naming species with a two-part Latin name consisting of the genus name and species identifier. Developed by Carolus Linnaeus, it provides a unique and universally recognized name for each species, avoiding the confusion of common names and facilitating clear communication among scientists worldwide.
Explanation:
Binomial nomenclature is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. This two-part name is called a binomial (meaning "two names" in Latin). The first part of the name identifies the genus to which the organism belongs, while the second part identifies the species within the genus. For example, the scientific name for humans is Homo sapiens, where Homo is the genus and sapiens is the species identifier.
The Swedish naturalist Carolus Linnaeus is credited with developing binomial nomenclature in the 18th century, which revolutionized the way scientists named and classified organisms. It enabled clearer and more consistent communication among scientists from different regions and languages. When printed, the genus name is always capitalized and the species name is always lowercase, and both are italicized, for example, Felis catus for the domestic cat.
The convention of binomial nomenclature not only mitigates the confusion caused by local and common names but also provides each species with a unique and universally recognized name. This universal nomenclature facilitates accurate communication and information sharing among biologists and researchers across the globe.

A grown tiger began its life as a single fertilized egg. Which explains why a tiger
looks so much different as an adult than it did as a single fertilized egg.
All the genes are expressed.
Different genes are expressed at different times
Different cells have different genes.
As a tiger grows his genes change.
Answer:
As a tiger grows his genes change
Explanation:
Development from a fertilized egg to a mature organism depends on the expression of different genes at different times. In addition, gene expression can occur in different parts of the body at different times during development. As the fertilized egg begins to divide, different genes are either turned on or off. The activation of specific genes is the most important step in cell differentiation. As the tiger grows and develops, different genes are either turned on or off in the tiger’s various cells. This regulation is a key part of development and differentiation.
what’s the difference between a dominant allele and a recessive allele
Answer:
key difference between dominant and recessive alleles is that dominant alleles are the alleles that give the phenotype, masking over the other phenotype, while recessive alleles are the alleles that are suppressed by the dominant allele.
Explanation:
Final answer:
A dominant allele is expressed in an organism's phenotype even if only one copy is present, while a recessive allele is only expressed if two copies are present. This expression pattern determines the visible traits, with dominant alleles masking recessive ones in heterozygous individuals.
Explanation:
Difference Between Dominant and Recessive Alleles
The main difference between a dominant allele and a recessive allele lies in their expression in an organism's phenotype. A dominant allele is always expressed in the phenotype even if just one copy is inherited. In contrast, a recessive allele can only be expressed in the phenotype if two copies are present. This means that in a heterozygous individual (one who has different alleles at a particular gene locus, such as 'Aa'), the dominant allele (A) will mask the expression of the recessive allele (a).
As an example, if we consider the ABO blood group system, an individual inheriting one allele for blood type A and one for blood type O will have the blood type A because A is dominant over O. Meanwhile, for a person to have blood type O, a recessive trait, they must inherit two O alleles.
It is important to understand that dominance does not imply superiority or higher frequency in the population but simply reflects the mechanism of inheritance and expression of certain characteristics. Indeed, the same allele can be dominant in relation to one allele and recessive to another, illustrating the context-dependent nature of these terms.

Read the passage and answer the following question.
Antibiotics are drugs used to treat bacterial infections. This class of drug was first developed in the 1920s. At that time, infectious diseases were the leading cause of death worldwide. Within two decades of the introduction of antibiotics, almost every major bacterial disease could be effectively cured with an antibiotic. In the late 1960s, Surgeon General William Stewart reported to Congress that infectious diseases would soon be a thing of the past. Little did he know that the process of natural selection would soon prove his words false.
As antibiotics were dispensed for practically every ailment, some bacteria developed mutations that allowed them to become resistant to specific antibiotics. Through natural selection, these bacteria rapidly multiplied and spread, effectively neutralizing the effectiveness of one antibiotic after another. Today, strains of bacteria that cause tuberculosis, staph infections, and other infectious diseases are almost completely untreatable with antibiotics. Experts predict that the problem will continue to grow and can only be held in check by the discovery of new drugs.
Using evidence from this passage explain how bacteria provided an example of natural selection.
The bacteria which had mutation became resistant to the antibiotic and survived and keeps on increasing, promoting natural selection.
Explanation:
The bacteria rapidly divide, the chances of mutation in the gene increases manifold.
The strains of bacteria causing tuberculosis and staph infection got mutated at DNA level such that they became resistant to antibiotics when tested those susceptible did not survive. These mutations were not harmful to bacteria and the resultant bacteria survived.
These bacteria which survived and proliferated as the environment was in their favour.
Thus, Darwin's Theory of Natural Selection is acceptable here as it says if a mutation is occurring towards the increase in population, they will be selected ones.

What is the product of a DNA synthesis reaction?
Answer:
The product of the DNA synthesis reaction is that, from a DNA molecule, two identical molecules of this nucleic acid are obtained.
Explanation:
The DNA replication process involves a series of events that result in obtaining two DNA molecules with the same sequence of nitrogen bases relative to the original. This must occur previous to the process of cell division, so that each cell daughter possesses the same genetic information.
For this process to occur the double DNA chain must be unrolled and, from each of the simple chains a complementary chain is formed, by adding complementary nitrogen bases: adenine with thymine and cytosine with guanine. DNA synthesis is facilitated by the action of the enzyme DNA polymerase.
DNA synthesis is called semi-conservative, as each molecule obtained in the process has a simple chain, coming from the original molecule, and a new synthesized chain.

https://brainly.com/question/793801
Final answer:
The product of DNA synthesis is two identical DNA molecules, comprised of one original strand and one new strand. This replication process ensures genetic information is preserved.
Explanation:
The product of a DNA synthesis reaction is two identical DNA molecules, each consisting of one original and one newly synthesized strand. This process, known as replication, occurs within the nucleus of a cell during the S phase of the cell cycle. Enzymes such as DNA polymerase play a pivotal role in this process, 'unzipping' the original double helix to use as templates for synthesis. Free deoxynucleoside triphosphates (dNTPs) are aligned opposite their complementary bases on each template strand, and DNA polymerase catalyzes the addition of these nucleotides to the 3' end of the growing chain. Thus, each daughter DNA molecule is an accurate copy of the parent DNA, ensuring genetic information is preserved during cell division.
What two types of cells contain chloroplasts?
Answer:
The two types of cells those contain chloroplasts are plant cells and algae.
Explanation:
Chloroplasts are double membrane bound cell organelles of plant cell which has envelope, stroma and lamellar system. It is found in green plants and algae as a photosynthetic apparatus. It contains chlorophyll which is a photosynthetic pigment that receives the energy from sunlight to converts it into the energy molecules called ATP. The shape of chloroplast is variable ; most common is discoid.Final answer:
Plant cells and algal cells are the two types of cells that contain chloroplasts, which are organelles responsible for photosynthesis.
Explanation:
Two types of cells that contain chloroplasts are plant cells and algal cells. Chloroplasts are special organelles where the process of photosynthesis takes place, using chlorophyll to convert solar energy into chemical energy in the form of glucose, which serves as food for the plant. In addition to plant cells, some groups of eukaryotes called algae also contain cells equipped with chloroplasts. Like plant cells, algal cells can have one or more chloroplasts, which are important for their photosynthetic activities.
Photosynthetic cells in plants are typically found in the mesophyll, the middle layer of cells in leaves. In aquatic environments, algae harness light energy with the help of chloroplasts as well. The presence of chloroplasts is fundamental to these organisms, as it allows them to produce their own food through photosynthesis, defining their role as autotrophs within ecosystems.
