Identify the two gases exchanged between the body and the air during respiration explain how this gas exchange happens.
Answer:
The two gases involved in gas exchange are oxygen and carbon dioxide. Oxygen from the air is absorbed by the blood, and carbon dioxide is released. This gas exchange occurs in the alveoli.
Explanation:
This is what i did thank you have a nice day ☺️
The two gases exchanged between the body and the air during respiration are Carbon dioxide and oxygen.
What is respiration?Respiration is defined as a metabolic process wherein, the living cells of an organism obtains energy (in the form of ATP) by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.
The human body is designed to exchange gases with the external environment or atmosphere. The external environment consists of numerous gases and oxygen being a vital gas is an essential part of the body.
Thus the exchange of gases in the human body takes place through the lungs and exchange takes place between the oxygen which is taken in and carbon dioxide is given out.
Million of alveoli in the lungs work to make it happen. Hence these gases are Carbon dioxide and water.

how the structures of the different chambers and vessels of the heart relate to their functions.
Answer:
Explanation:
The heart can be found at the center of the chest, underneath the sternum in a thoracic compartment. It is made up of four chambers and several valves that regulate the normal flow of blood within the body.
Two chambers called atria are located in the upper portion of the heart and receive oxygen-free blood. The valves that separate these chambers are called atrioventricular valves which is composed of the tricuspid valve on the left and the mitral valve on the right.
On the other hand, ventricles are chambers found on the lower portion of the heart; they pump oxygen-enriched blood into all organs of the body, reaching even the smallest cells. Similar to the atria, the ventricular chambers are also separated by valves. Collectively-termed as semilunar valves, these are comprised of the pulmonary and aortic valve.
The heart also has a wall that is composed of three layers: the outer layer epicardium (thin layer), the middle layer myocardium (thick layer), and the innermost layer endocardium (thin layer). The myocardium is think because it is made up of cardiac muscle fibers.
The structure of the heart is made more complex because of the mechanisms that allow blood to be distributed throughout the body and to return into the heart. Facilitating this continuous process are two types of blood vessels: veins and arteries (16jacktwinwritters). The vessels that bring oxygen-free blood back into the heart are called veins; those that bring oxygen-rich blood away from the heart and to other body parts are called arteries. Functioning in the left ventricle, the largest artery is called aorta. The aorta is considered a main artery in the body. It further splits into two smaller arteries called common iliac arteries.
With regular functioning, the heart is continuously able to supply sufficient amount of oxygen to all parts of the body.

In a paramecium, the nucleus divides first and then the cytoplasm divides, forming two identical daughter cells. Which type of reproduction takes place in paramecia?
Answer:
This type of reproduction is called binary fission.
Explanation:
Binary fission is a type of reproduction in paramecium that involves producing two identical daughter cells from one mother cell. These daughter cells are called clones, and are not genetically distinct from their progenitor. No genetic exchange is involved and they are genetically indequingishable.
The resulting DNA is identical to the original copy and newly copied chromosomes separate into two identical daughter cells with the same chromosome number. All offspring remain identical.

Answer:
This question is incomplete
Explanation:
This question is incomplete but there are some general facts that can be made.
Firstly, mitosis only occurs in meristematic tissue of plants which includes apical and lateral meristems
There are 4 phases in a cell cycle
1) G1 (gap 1) phase: This is the first phase of the cell cycle that has to do with an increase in the size of the cell. Major cellular components duplicate in size here.
2) S-phase: DNA replication occurs here.
3) G2 (gap 2) phase: This is the gap phase that comes after the S-phase. The cell undergoes further growth here and the organelles of the cells are also prepared for cell division.
4) Mitotic phase: There are four stages here
i) prophase: Chromosome condenses and becomes visible at this stage. And there is the emergence of spindle fibre from centrosomes.
ii) metaphase: Spindle fibre develops and sister chromatids are attached to
separate spindle.
iii) anaphase: Cohesin, which holds two sister chromatids (of chromosomes) together, breaks down and are pulled towards opposite poles.
iv) telophase: Chromosomes begins to decondense at opposite poles and actual cell division starts as mitotic spindle breaks down.

Explanation:
Natural selection refers to all of the following EXCEPT
Answer:
Darwin proposed the theory of natural selection to explain the process of evolution. According to Darwin’s theory of natural selection, all organisms have the potential to reproduce limitlessly irrespective of the fact that each species maintain a constant density over time. However, the struggle for existence, i.e. the competition among individuals for available resources to survive and reproduce, put a check on species density (D) and maintains it at a constant level (B). Survival of fittest is unequal ability of individuals to survive and reproduce based on suitability of their inherited characters to prevailing environmental conditions (A). It imparts the reproductive advantage to certain organisms which account for major part of the gene pool of the species. Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition (E). Thus, the correct answer is option C.

If the gametes produced by a given organism contain 6 chromosomes, how many chromosomes are found in that organism's body cells? (4 points) 3 6 12 10
hi
gamete are reproduction cells. They carry only half of the DNA materials
for the merger with an other gamete celle from the opposite sex.
so if a gamete carries 6 chromosomes, normal load of other cells is 12
If the gametes of a given organism contain only 6 chromosomes then in that same organism's body cells, the number of chromosomes will be 12. Thus, the correct option is C.
What are Chromosomes?A chromosome is a long molecule of DNA with some part of it or all of the genetic material of an organism. Most of the eukaryotic chromosomes contain packaging proteins called histone proteins which are aided by chaperone proteins in the nucleus, that bind to and condense the DNA molecules present in the nucleus to maintain its integrity. The DNA molecule is a long thread which is several meters in length.
The chromosome content of gamete cells is half than the parent cell. It is because they are produced from meiosis. The male and female gametes combine in fertilization to form the zygote which is diploid (2n). Here, the chromosomal content of gametes is 6 i.e., haploid (n) thus the chromosomal content of body cells will be 12 (2n).
Therefore, the correct option is C.

List three types of fertilization with a description.
Answer:
oviparity, ovoviparity, and viviparity
Explanation:
oviparity- expulsion of undeveloped eggs rather than live young. The eggs may have been fertilized before release, as in birds and some reptiles, or are to be fertilized externally, as in amphibians and many lower forms.
ovoviparity-embryos develop inside eggs that remain in the mother's body until they are ready to hatch.
viviparity- , retention and growth of the fertilized egg within the maternal body until the young animal, as a larva or newborn, is capable of independent existence
Answer:
Oviparity- fertilized eggs are laid outside the females body and develop there.
ovoiparity- eggs that have been fertilized before being released.
viviparity- development of embroy inside the mother
