5. What muscle is below the deltoid and is attached to the ulnar process? How many heads does this muscle have?
Answer:
What muscle is below the deltoid and is attached to the ulnar process? How many heads does this muscle have?
Explanation:
Triceps is the muscle that is responsible for the extension of elbow joint and also contribute to extension of shoulder joint. This muscle have three origin, that's why the name triceps. The triceps muscle has three heads which are:
A. The long head originates from the infraglenoid tubercle of scapula.
B. The lateral head originates from above the radial Grove in humerus.
C. The medial head originates form below the radial Grove in humerus.
These heads meet to form the body of triceps which gets inserted as triceps tendon in the olecranon process of ulna just behind the elbow. The contraction of this muscle causes the extension of the elbow joint.
Deltoid muscles are in your shoulder, which is the ball-and-socket joint that connects your arm to the trunk of your body. Deltoid muscles help you move your arms in different directions.
What is Deltoid muscle?The muscle known as the triceps is in charge of extending the elbow joint and helping to extend the shoulder joint. The name triceps refers to the fact that this muscle has three origins.
The scapula's infraglenoid tubercle is the source of the long head. In the humerus, the lateral head develops from above the radial Grove. In the humerus, the medial head develops from below the radial grove.
The triceps body is formed when these heads come together, and it is placed as the triceps tendon in the ulna's olecranon process, right beyond the elbow. The elbow joint extends as a result of this muscle contracting.
Therefore, Deltoid muscles are in your shoulder, which is the ball-and-socket joint that connects your arm to the trunk of your body. Deltoid muscles help you move your arms in different directions.

Answer:
It explains facts and allows people to make predictions.
Explanation:
In everyday life, the word theory often means an untested hunch, or a guess without supporting evidence. A theory not only explains known facts but also allows scientists to make predictions of what they should observe if a theory is true.
In science, the term theory is applied only to ideas that are supported by a vast, diverse array of evidence. The term is also used in everyday life based on personal beliefs which does not support any strong evidence.
What is scientific theory?In science, a theory is a term applied to a well-explanation of an aspect of the natural world on the basis of empirical evidence that has undergone rigorous testing and evaluation. The process involves collecting and analyzing data and observations and hypotheses are based on the data obtained which form the basis of scientific theory. Therefore, scientific theory is an explanation that has been verified by scientific researchers.
However, the term theory is casually used in everyday language without any scientific proof. For example, someone may say "I have a theory that the universe fake". This fact is casually spoken by a person which is not based on any scientific fact.
Scientific theories are based on evidence supported by rigorous testing, while everyday theories are based on personal beliefs without any strong evidence.

what is the last structure of the air passageway in your lungs
Answer:
Bronchioles
Explanation:
You inhale through your nose and the air is filtered. It goes down the pharynx. It goes through the larynx. A "door" called the epiglottis opens during breathing. Then it enters the trachea. (windpipe) It goes through the bronchus. The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air. Air ends its pathway in the ________. (I bet you can guess because you're so smart!) They're surrounded by capillaries that connect the pulmonary arteries and veins. This enables the transfer of oxygen and carbon dioxide.

The statements about meiosis that are false include the following:
C. During meiosis II, paired homologous chromosomes move up to the equator of the cell.
G. In meiosis II, ploidy is reduced.
H. During anaphase I, sister chromatids separate.
Meiosis can be defined as a type of cell division or duplication that occurs in all body cells found in living organisms, through which a single cell divides twice to produce four (4) haploid cells (gamete).
During cell division, deoxyribonucleic acid (DNA) must be replicated before meiosis can take place in any body cell found in living organisms.
Generally, the phases or steps that occur during meiosis include:
Prophase I.Metaphase I.Anaphase I.Telophase I.Prophase II.Metaphase II.Anaphase II.Telophase II.Furthermore, the statements about meiosis that are false include the following:
1. During meiosis II, paired homologous chromosomes move up to the equator of the cell.
The movement of paired homologous chromosomes to the equator of the cell takes place during prophase II.2. In meiosis II, ploidy is reduced.

A group of scientists is studying a certain species of mouse. Previous genetic analysis has shown that fur color in this species is controlled by a single gene that has two alleles: a dominant allele (FF) that is associated with dark fur, and a recessive allele (ff) that is associated with light fur. The scientists collected data about a population of these mice to help determine the population's fur color allele frequencies. They found that out of 952 mice in the population, 238 mice had light fur.

how does oxygen have a direct effect on sea urchins
Answer:
When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through its body (through the canals). Carbon dioxide (waste/not good stuff) is released through the anus. The Purple Sea Urchin obtains oxygen through diffusion only (the diffusion of oxygen into the organism).
Explanation:
Brainliest please
Sea urchins breathe through their feet tubes because of nonavailability of lungs and gills in them. When the oxygen level is low at that time, the sea urchins pump fluids through their anus.
How are sea urchins able to survive sea ?Sea urchins are able to survive in sea because of the tiny hair called spines present on their body as water currents are created because of the hair and waste gets washed away with the water currents created.
When the carbon dioxide level gets increased in the sea at that time the skeletal structures of the marine animals are also affected.
The shells made up of calcium also gets affected because of the increasing acidity in the water. Carbon dioxide not so good is released through the anus and this totally affects the normal regulation of the creature.
