Why do roots always grow in a downward direction, no matter which way you turn the seed or seedling?
because roots weigh more than any other plant part
because the plant’s stem begins to grow, and it pushes the roots downward
because that is the direction that roots find necessary water and nutrients
because the root contains hormones that make it grow away from the sun

Respiration begins when air enters the mouth and nose. As air goes down the trachea, or windpipe, tiny hairs called cilia gently wave to keep dirt and mucus out. At the bottom of the trachea are two tubes called bronchi. One bronchus goes into the left lung, and the other goes into the right lung. When you inhale, the diaphragm muscle between the lungs and abdomen contracts, making room for the lungs to expand.
Which of these best describes how the lungs and diaphragm affect each other?
A
As the lungs expand, the diaphragm expands.
B
As the lungs expand, the diaphragm contracts.
C
As the lungs contract, the diaphragm contracts.
D
The lungs and diaphragm have no relationship.

What is Mineral composition?A mineral in a geological sense is not the same as the phrase "minerals" as used on nutrition labels and pharmaceutical items. The traditional definition of a mineral in geology is one that has the following criteria: 1) naturally occurring, 2) inorganic, 3) solid at room temperature, 4) regular crystal structure, and 5) specified chemical composition.
Although they technically shouldn't be classified minerals, several natural substances are. Mercury and water, for instance, are both liquid at ambient temperature.
Because both were categorized prior to the room-temperature rule being acknowledged as a component of the definition, they are both regarded as minerals.

Construct an explanation that describes how matter moves through your body during cellular respiration.
Answers
Cellular Respiration: The process by which organisms break down glucose into a form that the cell can use as energy.
Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body's cells. Initially ... Cellular respiration can be described as the reverse or opposite of photosynthesis.
Cellular respiration is a set of chemical reactions cells use to change the food we eat, the water we drink, and oxygen from the air we breathe into forms the cell can use as energy. In the process, matter is transformed from one type to another; that is, atoms from these materials are arranged into new forms.
In this exercise we have to use our knowledge of biology to describe how cellular respiration occurs, so we can say that:
We can say that the respiratory process uses energy and oxygen to have the ability to move through the body.
How does cellular respiration take place?Cellular respiration is a process by which organisms obtain energy to perform the most diverse activities. Cellular respiration occurs in mitochondria, in the presence of oxygen, and is divided into three steps: glycolysis, the citric acid cycle (or Krebs cycle) and oxidative phosphorylation.
What are the steps of cellular respiration?Cellular respiration is a process that involves 3 steps:
Glycolysis, which takes place in the cytosol. Citric acid cycle, which occurs in the mitochondrial matrix. Oxidative phosphorylation, which occurs in the inner mitochondrial membrane.Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body's cells.

A
They are classified in a hierarchical system, with the largest group sharing only a few characteristics at the top, and the smallest group sharing the most characteristics at the bottom.
B
They are classified in a numerical system, where the top tier classifies organisms with the largest populations, and the lowest tier classifies organisms with the smallest populations.
C
They are classified in a chronological system, starting with the first organisms discovered by people and through to the most recently discovered organisms.
D
They are classified in a geographical system, where the organisms are listed alphabetically by country, and the countries are ordered by number of organisms they possess.
Answers
It aids in both the identification of living things and the comprehension of their diversity. We may learn about the characteristics, similarities, and differences of many plant and animal species thanks to classification. Thus, option C is correct.
What classifying organisms in science?The study of relationships among living things is known as taxonomy, and the formal classification of species into groups based on those supposed relationships is known as taxonomy. The similarities and differences between organisms are used to classify them.
Scientists classify things using a branching method. The domain is the largest category. Kingdoms are the next level of division within each domain, followed by phyla, classes, orders, families, genus, and species. It helps us comprehend how more sophisticated organisms develop from less complicated ones.
Therefore, They are classified in a chronological system, starting with the first organisms discovered by people and through to the most recently discovered organisms.

What blocks the society from becoming universal?
Answers
Answer:
Some of Robert Owen's ideas were confirmed by personal experience as a philanthropic employer who strongly emphasised the importance of environment, education and, ultimately, cooperation in improving social conditions. Owen was closely involved with the factory movement (for the improvement of working conditions), Poor Law reform, public education, economic regeneration in post-Napoleonic War Britain, the relief of distress in Ireland, creating what he called ‘communities of equality’ in Britain and America, and, after 1830, trade unionism and cooperation. He supported religious toleration. He advocated sexual equality, marriage and divorce law reform, and alluded to birth control as a means of regulating population. He thus gained fame, even notoriety, as a social and educational reformer, and long after his death continued to inspire others, notably through the ideas presented in his most important and famous work, the essays in A New View of Society.
Explanation:
The things which block the society from becoming universal include the crime, poverty, and the misery in the society.
What is a Universal society?Cultural universals can be best described as the concepts, social constructs, or the patterns of behavior which are common to all the human cultures. This means that every society in existence in the nature generally exhibits some form of the universal.
Society may be formed so as to exist without any crime, without poverty, with the health greatly improved, with little, if any kind of misery, and with intelligence and happiness which are increased a hundredfold and also with no obstacle whatsoever intervenes at this moment of time except the ignorance to prevent such a state of society from becoming universal.
