Phenyl acetic acid is not a type of fatty acid (option D
What is a fatty acid?A fatty acid is a long-chain carboxylic acid. It consists of a hydrocarbon chain with a carboxyl group at one end. Fatty acids are found in animal and plant fats, and they are an important part of the human diet.
Phenyl acetic acid is not a fatty acid because it does not have a long carbon chain. It is a short-chain carboxylic acid with only six carbon atoms. Short-chain carboxylic acids are not considered to be fatty acids.

The diagram shows a simplified version of how the blood moves around the body of an animal. Is the blood at point D oxygenated or deoxygenated?
Answer:
oxygenated
hope u got your answer
In the given diagram, point D is oxygenated blood, as it carries oxygen from heart to cells.
What is heart?The main organ of your cardiovascular system, a network of blood vessels that pumps blood throughout your body, is your heart.
It also collaborates with other bodily systems to regulate your heart rate and blood pressure. Your family history, personal health history, and lifestyle all have an impact on how well your heart functions.
The heart is located between the two lungs, slightly to the left of center, behind the breastbone in humans. It is supported by the diaphragm, the muscular wall that separates the chest from the abdominal cavity.
It's the muscle at the heart of your circulatory system that pumps blood throughout your body as your heart beats. This blood transports oxygen and nutrients to all parts of your body while removing waste and carbon dioxide.
Here, the red vessels are arteries while blue vessel is vein, arteries always carries oxygenated blood and vein carries deoxygenated blood.
Thus, the point D carries oxygenated blood.

so A should be the answer
Explanation:
Briefly explain how the volume in your thoracic cavity changes during inhalation and exhalation. Be sure your answer includes how those changes in volume lead to air moving in and out. Include which gas, oxygen or darbon dioxide regulates respiration rate.
Answer:
Both inhalation and exhalation depend on pressure gradients between the lungs and atmosphere, as well as the muscles in the thoracic cavity.
Explanation:
The thoracic cavity, or chest cavity, always has a slight, negative pressure which aids in keeping the airways of the lungs open. During the process of inhalation, the lung volume expands as a result of the contraction of the diaphragm and intercostal muscles (the muscles that are connected to the rib cage), thus expanding the thoracic cavity. Due to this increase in volume, the pressure is decreased, based on the principles of Boyle’s Law. This decrease of pressure in the thoracic cavity relative to the environment makes the cavity pressure less than the atmospheric pressure. This pressure gradient between the atmosphere and the thoracic cavity allows air to rush into the lungs; inhalation occurs. The resulting increase in volume is largely attributed to an increase in alveolar space because the bronchioles and bronchi are stiff structures that do not change in size.During this process, the chest wall expands out and away from the lungs. The lungs are elastic; therefore, when air fills the lungs, the elastic recoil within the tissues of the lung exerts pressure back toward the interior of the lungs. These outward and inward forces compete to inflate and deflate the lung with every breath. Upon exhalation, the lungs recoil to force the air out of the lungs. The intercostal muscles relax, returning the chest wall to its original position. During exhalation, the diaphragm also relaxes, moving higher into the thoracic cavity. This increases the pressure within the thoracic cavity relative to the environment. Air rushes out of the lungs due to the pressure gradient between the thoracic cavity and the atmosphere. This movement of air out of the lungs is classified as a passive event since there are no muscles contracting to expel the air.

Describe the general temperature of ocean currents near the equator and the poles.
Answer:
Currents flowing away from the Equator are generally warm.
Explanation:
That is because the Equatorial regions is the source of warm air and water. Ocean currents flowing from the Equator thus carry this warm water with them. The most prominent example is the Gulf Stream in the Atlantic Ocean, which runs most of the way to the North Pole and brings mild winter climates in its wake to adjacent coastal areas. In the Pacific Ocean the Alaska Current likewise carries warm water northward making Anchorage, Alaska much milder in winter than inland areas with the same latitude.

Why does the pectoral girdle need to be flexible while the pelvic girdle needs to be rigid?
Answer:
Flexibility: pectoral girdle is more flexible-less ligaments, ball and socket joint is shallower
Security: pelvic girdle is more secure, deeper socket. there are more dislocated shoulders than dislocated hips
ability to bear weight: pelvic girdle can bear more weight-the pelvic girdle has bones that are fused (os coxa) and a joint with the sacrum. the pectoral girdle has a little bone called the clavicle connecting it to the body wall.
Explanation:
The pelvic gridle is rigid to protect internal organs and support body weight whereas pectoral gridle require to provide movement to upper limbs.
The girdles are part of the appendicular skeleton which is attached to upper limbs and lower limbs, The upper limbs attach to pectoral gridles and lower limbs attached to pelvic gridles.
1. The pectoral gridle:
connects your upper limbs to the bones along the axis of your body.The pectoral girdle has two bones clavicle, or collarbone and scapula, or shoulder blade.it has ball and socket joint that provide movement to the upper limb.2. The pelvic gridle:
made up of left and right coxal bones and sacrumattached to legs or lower limbs therefore, called hipbonessupports body weight and protect internal organsit is rigid needed to support the weight of the body.Thus, the correct answer is - The pelvic gridle is rigid to protect internal organs and support body weight whereas pectoral gridle require to provide movement to upper limbs.
