Answer:
Explanation:
(A) Heterotrimeric G-proteins are composed of three distinct subunits (α, β, and γ). Receptor activation causes the binding of the G-protein and the α subunit to exchange GDP for GTP, leading (more...) The second class of GTP-binding proteins are monomeric G-proteins (also called small G-proteins).
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.

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.

A group of students discusses what they
believe will be the outcome of an experiment
they are about to conduct. Each student
records a statement that will either be
proven or disproven by the experiment.
Each member of the group carefully watches
as the experiment proceeds. One group
member writes down the comments of the
group as they call out what they see.
After the experiment is complete, the group
discusses their observations. They review their
notes and create a graph that shows the
results of the experiment. The group
discusses what these findings might mean.
Now that the group has decided on a
hypothesis, they are ready to proceed with
the experiment. As they work, the group is
cautious to test only one variable at a time
and to follow all directions carefully.

The group reviews their notes and the data
they have collected. After a short discussion,
they decide whether or not the original
hypothesis is correct.
A science group begins a discussion related to
