Answer:
Respiratory and circulatory
Explanation:
The Circulatory System Works in Tandem with the Respiratory System. The circulatory and respiratory systems work together to sustain the body with oxygen and to remove carbon dioxide. Pulmonary circulation facilitates the process of external respiration: Deoxygenated blood flows into the lungs.
The two systems which are most directly involved in this process are respiratory and circulatory systems.
What do you mean by oxygen-rich blood?In the lungs, oxygen is put into the blood, and carbon dioxide is taken out of the blood during the process of breathing. After the blood gets oxygen in the lungs, it is called oxygen-rich blood.
During the whole process of breathing, the respiratory and circulatory systems play a major role in the separation of oxygen-rich and oxygen-poor blood.
Therefore, the two systems which are most directly involved in this process are the the respiratory and the circulatory systems.

12. Traits are determined by the proteins that are synthesized according to instructions coded in DNA. Which sequence of biomolecules is responsible for the coded instructions?
A enzymes
B nucleotides
C glycoproteins
D carbohydrates
Answer:
B. nucleotides
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
In conclusion, the proteins which are mainly synthesized based on the genetic instruction codes in deoxyribonucleic acid (DNA) determines the trait of living organisms. A sequence of biomolecules which are responsible for this coded genetic instructions in all living organisms is known as nucleotides.

Examine the following mutation: ACGGGCAAACGATTG →
ACGGGCAACGATTG. The mutations is
Answer: a frame shift mutation
Explanation:
ACGGGCAAACGATTG to ACGGGCAACGATTG, and the mutation is a deletion mutation, as there is a deletion of the adenine base out of three adenines. as there is a deletion of a single base, ,so it is called a deletion mutation.
What is mutation?This change can have various effects on the resulting protein, depending on the specific location of the mutation within the gene and the role of the affected amino acid in the protein's function. For instance, in a non-coding region of the gene, such a mutation might have no effect at all on the protein, as it would not affect the sequence of the mRNA that is transcribed from the gene. However, if the mutation occurs in a coding region of the gene, it can lead to a change in the resulting protein.
Hence, ACGGGCAAACGATTG to ACGGGCAACGATTG, and the mutation is a deletion mutation, as there is a deletion of the adenine base out of three adenines.

Anoles are a family of IIzards found throughout the Americas. Green anoles, Anolis carolinensis, are native to i specific area of Florida. In this
area, the primary territory of green anoles was once along the ground and in low-level branches. However, the Introduction of brown anoles,
Anolis sagrei, from Cuba forced green anoles to shift o their territory to the tops of trees. The branches at the treetops are smoother and thinner
than those close to the ground. Over time, the toe pads of the green anoles have become larger and stickler.
What is the best explanation for the change In green anoles' toe pads?
Some individuals In the green anole population had mutations that helped them survive and reproduce In the new conditions,
so thelr genes were passed on to the next generation.

if two chromosome have equal length and size , and different in gene number would severity of chromosomal abnormalities in this two chromosome are equal?
Answer:
Unequal.
Explanation:
The severity of chromosomal abnormalities in these two chromosome are unequal that are equal in length and size but unequal in gene number are because the gene number are different from one another. If the size of gene increase or decrease from the normal range then it will leads to chromosomal abnormalities in the cell so the cells that has normal gene number has normal chromosome as compared to those cells where abnormal gene is present so the chromosomes are abnormal.

What is the genetic make-up of an organism?
Answer:
Explanation:
In a broad sense,genetic makeup of an organism can be regarded as the
"genotype" . It gives description about
complete set of genes an organism.
If we narrow it, it can be reffered to as "alleles" , this is is variant forms of a gene which is been carried by an organism. For instance, Humans can be regarded as diploid organisms, i.e there are two alleles at their each genetic position along with one allele which is been inherited from each parent. genotype of a specific gene is been represented by "Each pair of alleles". Instance of this is of "sweet pea plants" the gene responsible for flowering color posses two alleles, One of the alleles is responsible for coding purple flowers, symbolized with
uppercase letter F, the other allele is responsible for coding of white flowers
symbolized with Lowercase letter" f "
There are three possible genotypes which could be featured for Different population of a sweet pea, which are
✓FF
✓Ff
✓ ff.
Genotype of each plant have some contribution to the phenotype, by saying this, we mean outward appearance of its flowers.

What is the biggest error, methodologically, in the following scientific study? "The goal of the study was to determine whether the ebola virus is as deadly in rhesus monkeys as it is in gorillas. I took a sample of four healthy rhesus monkeys and four healthy gorillas. The animals were a random mixture of sexes and ages. I arranged eight cages so that each animal would be in a separate cage, and I made sure there would be no contact among the cages that would allow transmission of the virus. Then I obtained a sample of the ebola virus from the National Institute of Infectious Diseases and injected all the monkeys and gorillas with the same size dose. At the end of four days, I noticed that all the gorillas were dead but only one of the monkeys was dead. An autopsy revealed that three of the four gorillas had died of ebola fever but that the fourth, nicknamed Curious George, had died of internal bleeding after swallowing the small pair of scissors that were left within reach of its cage. The dead monkey had died of ebola fever. At the end of two months there were no more deaths. I concluded that my dosage of the ebola virus is three times as likely to be deadly to gorillas as it is to rhesus monkeys, but I recommended repeating the study to see if the percentages of deaths due to ebola fever remained steady over a wide range of dosages of the virus."
Answer:
The sample obtained for the study is not enough. Also, a control group is not established thus making the study erroneous.
Explanation:
The total sample size of 4 specimens from each of the two groups does not qualify as an appropriate sample size for the generalization of the results. Furthermore, the mixing of different ages and genders is not suitable for this kind of sample.
Also, the control group is not established where healthy specimens are kept in a similar environment to factor out the effects of the environment and other components on the health/death of the animals.
