Answer: When the oxygen-rich blood gets to the cells, the cells receive the oxygen and release the carbon dioxide. The blood with less oxygen and a lot of carbon dioxide returns to the heart. Then the heart returns this blood to the lungs where carbon dioxide is released and oxygen is received.

Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.

<h3>
Qu'est-ce que l'ADN ?</h3>
L'ADN (acide désoxyribonucléique) est un type d'acide nucléique qui se distingue par le stockage de l'information génétique de la grande majorité des êtres vivants. Cette molécule est formée de nucléotides et a généralement la forme d'une double hélice.
Il est nécessaire de prélever des échantillons de certains fluides corporels qui peuvent être du sang, de la salive, des ongles, des cheveux ou du sperme. À l'aide de techniques de laboratoire sophistiquées, l'ADN des échantillons est isolé, puis une cartographie est effectuée, ce qui est fait par des équipements appelés "Séquenceurs d'ADN".
Pour le prouver, normalement le rapport d'un examen ADN apporte quels gènes et chromosomes ont été étudiés et l'analyse du généticien à leur sujet. Les résultats sont présentés dans des rapports simples et clairs. Dans les examens de paternité, le résultat est toujours comparatif.

Answer:
MRCORRECT has answered the question
Explanation:
After atmospheric carbon dioxide dissolves into the ocean, the aqueous carbon dioxidereacts with seawater to form carbonic acid. As carbonic acid continues to interact with water molecules, carbonate is formed, which increases the concentration of hydrogen ions in the ocean and consequently reducesocean pH.
Answer:
The term "disease" refers to conditions that impair normal tissue function. For example, cystic fibrosis, atherosclerosis, and measles are all considered diseases. However, there are fundamentally different causes for each of these diseases. Cystic fibrosis (CF) is due to a specific genotype that results in impaired transport of chloride ions across cell membranes, leading to the production of abnormally thick mucus. Thus, CF is most accurately called a genetic or metabolic disease. Atherosclerosis, which can lead to heart attacks and strokes, may be considered a disease of aging, because it typically becomes a problem later in life after plaques of cholesterol have built up and partially blocked arteries. In contrast, measles is an infectious disease because it occurs when an individual contracts an outside agent, the measles virus. An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
