Answer:
Our organ systems in the human body perform functions such as digesting food, breathing and transporting important nutrients for the human body to function properly. Thus, while the digestive system processes food, the respiratory system provides oxygen and the excretor eliminates waste, the circulatory system connects the different systems for the human body to function.
Explanation:
When we eat, we incorporate different nutrients that provide us with the substances and energy that our body needs to function properly. The digestive system allows us to obtain these nutrients, while the circulatory system is responsible for carrying them throughout the body. The nutrition function, which allows the use of nutrients, is carried out by the digestive, circulatory, respiratory and excretory systems. Food, once ingested, is subjected in the digestive system to crushing and chemical transformation (digestion) that results in obtaining simpler substances, converting them into soluble and assimilable substances (nutrients) that are incorporated into the circulatory system and are transported to each of the cells of the tissues. A proportion of the oxygen that is part of the inspired air and that has penetrated the lungs, enters the blood circulation in the pulmonary alveoli. In this way, oxygen enters the circulatory system to be transported to all cells in the body.

which statement correctly describes greenhouse gases in the atmosphere?
Answer: It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.
Explanation:
Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.

Two populations live in the same habitat and compete for food. The first group is larger and multiplies through asexual reproduction; the second reproduces sexually. What could happen to cause the second group to outnumber the first?
Answer:
an environmental change that causes the larger but unadaptable species to die off
Explanation:
Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.
What happen when the process of meiosis does not takes place?If there has no process of meiosis takes place chromosome number will be doubled disturbing the genetic make up of the organism. If no meiosis has been takes place then the resulting of the zygote will be of double the number of the chromosomes. The genetic makeup would change entirely. The process of the meiosis halves the number of chromosomes in haploid cell and maintain the serenity of organism.
The process of the meiosis due to crossing over, genetic variation occurs which let the offspring receive favourable alleles to survive in new conditions and in the diploid organisms first the gametes are formed, then fertilization occurs and the diploid cell has formed which gives rise to the organism having diploid cells.
Therefore, Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.

Fossils. Fossils provide solid evidence that organisms from the past are not the same as those found today, and fossils show a progression of evolution. Scientists determine the age of fossils and categorize them from all over the world to determine when the organisms lived relative to each other.
Explanation:
frank has type A blood (AA or AO) and margarita has type B (BB or BO) blood. They have a new baby. Vinnie, with type O blood. Is this possible or should frank accuse margarita of cheating?
Answer:
It is technically possible, if and only if, both parents have AO and BO blood.
Explanation:
the only way (most of the time) a child can get O blood is if both genes accepted by the parents are O. That would mean both parents would have to have O recessive genes.
Which of the following is the function of nucleic acids?
A. Breakdown chemical compounds
B. Carry heredity information
C. Structural support
D. Short-term energy storage
Answer:
B. Carry heredity information
Explanation:
Nucleic acids are one of the four types of biological molecules in nature. The other three being: proteins, carbohydrates, lipids. Nucleic acids consists of Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA).
DNA is a nucleic acid found in the NUCLEUS of eukaryotic cells or nucleoid region of prokaryotic cells where it functions to store or hold genetic information for the cell. On the other hand, RNA functions to carry the stored information in order to be expressed. Hence, according to this question, the nucleic acid functions to carry heredity information.
Which stage of the cell cycle lasts longest?
Answer: i think the Interphase because
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.
