How are chordates further divided into three subphyla?
A. By their habitats
B. By the presence or absence of a notochord
C. By how they obtain food
D. By their body structures
Answer: D. By their body structures
Explanation:
They are divided into three subphyla which would be Vertebrate.
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 happens when an organism genome (genetic code) is incorrectly copied or changed?
Answer:
When there is a mistake in the copying of the genetic message that is permanent, a mutation has occurred. Two of the bases in DNA (Cytosine and Thymine) are the most vulnerable, and when this happens, they may pair with each other or themselves and the message is changed.

Which of the following is correct about classifying organisms in science?
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.
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.

1. What idea you had for inveting the telephone?
- "I basiclly used a battery to provide current on the phone line and to control its strength by using carbon to vary the resistance".
2.Did you once wanted to give up while creating an artwork?
My only answer and quote im giving is this: “I have not failed 10,000 times – I've successfully found 10,000 ways that will not work.”
3.What inspired you?
-"I got my intrest by The Civil War it got me interested in invention."
4.How did you came up with the materials for making with your inventions?
"One night, after absent-mindedly rolling between my fingers a piece of lampblack, the material he used in his telephone receiver, I got the idea for switching to a carbonized filament".
5. So, Last question. Why you have to fail to succeed?
"Failure makes you better."
You have to find a way to find success through failure, and so you open yourself up to new ideas and new solutions to the same old problems. It may be difficult to cope with the setback at first, but eventually, mistakes will excite you.

Which of these is not a principle of natural selection?
A. Over time, the offspring of individuals with helpful variations make up more of a population and eventually become a separate species
B. Variations are passed to offspring
C. Differences, or variations, occur among individuals of a species
D. Adaptations happen in a start stop fashion
Answer:
D
Explanation:
adaptations are passed down in natural selection but it’s not in start stop fashion
Answer:
D
Explanation:
Adaptations occur, but they don't just stop. In virtually every population, you will have variation, and therefore, adaptations. They aren't going anywhere.

Construct an explanation that describes how matter moves through your body during cellular respiration.
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.

What blocks the society from becoming universal?
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.
