Answer:
Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood. Common problems include allergies, diseases or infections The cells in our bodies need oxygen to stay alive. Carbon dioxide is made in our bodies as cells do their jobs. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is to move fresh air into your body while removing waste gases.The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.

A. the ability to reproduce asexually
B. the ability to make their own food
C. the need for a source of energy
D. the need for oxygen for respiration
Answer:
I am not sure but I believe it's c.the need for a source of energy
The characteristic is shared by all prokaryotic and eukaryotic organisms are that they need for a source of energy as to maintain the cell processes.
What is the difference between the prokaryotic and eukaryotic organisms?
The number one difference among those sorts of organisms is that eukaryotic cells have a membrane-certain nucleus and prokaryotic cells do not. The nucleus is wherein eukaryotes save their genetic information.
Mitochondria, for example, are organelles that offer eukaryotes with maximum in their power through generating power-wealthy molecules known as ATP. Prokaryotes lack mitochondria and as an alternative produce their ATP on their mobile floor membrane.Both eukaryotic and prokaryotic organisms get the power they want to develop and keep everyday cell characteristic thru cell respiratory. Cellular respiratory has 3 foremost stages: glycolysis, the citric acid cycle, and electron transport.

Select the correct answer.
In January, Earth is closest to the Sun in its orbit. Yet the Northern Hemisphere experiences winter. Which statement explains this phenomenon?
A.
Earth completes one precession cycle in January every year.
B.
The Northern Hemisphere is located at high latitudes.
C.
The Northern Hemisphere is tilted away from the Sun.
D.
The eccentricity of Earth’s orbit is high in January.
E.
The obliquity or tilt of Earth is greater than 23.5° in January.
Answer:
C. The Northern Hemisphere is tilted away from the sun
In January, Earth is closest to the Sun in its orbit, yet the Northern Hemisphere experiences winter because the Northern Hemisphere is tilted away from the Sun; this is option C.
What is Earth's axis tilt?The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to the plane of its orbit around the Sun. This tilt is the primary reason for the seasons on Earth. As the Earth orbits around the Sun, the orientation of its axis relative to the Sun changes, resulting in different parts of the planet receiving varying amounts of sunlight throughout the year. When the Northern Hemisphere is tilted away from the Sun, as it is in January, the Sun's rays hit the Earth at a lower angle, resulting in less direct and less intense heat and light. This means that the Northern Hemisphere receives less sunlight and experiences colder temperatures, resulting in winter.
Hence, in January, Earth is closest to the Sun in its orbit, yet the Northern Hemisphere experiences winter because the Northern Hemisphere is tilted away from the Sun, which is option C.

Answer:
it's carbon, sulfur, hydrogen, oxygen, and nitrogen (A, C, E, F, G)
Explanation:
The most essential elements for the survival of living organisms are carbon, hydrogen, oxygen, and nitrogen.
Why oxygen is an important element?Oxygen is important for respiration and the energy-producing process that drives most living things' metabolisms. This is considered an element that is important for the life.
All life forms on Earth require carbon. Carbon intake and outflow are a feature of every plant and animal life, whether they take in carbon to help build food or release carbon through respiration.
Therefore, Oxygen, carbon, hydrogen, and nitrogen are important elements as 96% of the human body will be made with them.

ANSWER: A NATURAL SELECTION.
EXPLANATION:
When allele has direct effects on the organism and the environment, it is termed natural selection. It either affects an organism positively by causing more DNA reproduction, leading to the increase in allele’s frequency, or negatively by decreasing it .
However, this shouldn't be mistakened for genetic drift, where allele increase or decrease is established in the random organisms that survived.
