did all the least complex organisms die off

Answers

Answer 1

Answer:

It's generally thought that the evolution of complex life was a rare, once-in-4.5-billion-years event. But new research suggests that conditions were right for complex cells to evolve and die off at least once - or perhaps several times - before our lineage even got started.

Are there certain food groups that you eat very little of? Which ones are they and why do you eat a lot of foods from those food groups?

ANSWER.​

Answers

Answer:

Starch, Dairy and grain foods.

Explanation:

Much of the food i eat are snacks , like chips, which are starch and crackers which are grain depending on what kind. I also eat dairy a lot like ice cream, milk, yogurt, and cheese. I eat more of this because i prefer snacks instead of meals bu am working to get back into eating meals.

Answer:

I don't eat any dairy, but thats because I'm lactose intolerant so it's not like I can control whether I have dairy or not.

On the other hand, I tend to eat a lot of fruits and vegetables because I like them. I don't think it's a problem since they're good for you. But everything is in moderation I guess.

If you are making a formal observation, you should:
Engage with the children
O Join in teaching and play activities
O Talk to the teachers about the children
O Sit quietly in a low, out of the way chair
O Record the children

Answers

Answer:

Talk to the teachers about the children

Explanation:

Because teachers know their children well in the lower school. Also, I feel like not engaging with the children, and sitting quietly in a low, out of the way chair, gets you nowhere because I've had experience with someone observing our class, and everyone was dead quiet, which is how keeping a low profile and keeping out of the way gets you nowhere when we already know your there and your watching us.

Which of the following is NOT true of the diaphragm?
It is considered to be the prime mover for inhalation,
Its action is to flatten during inspiration.
When it contracts, it compresses the thorax and decreases its volume.
All of these are true of the diaphragm.

Answers

Answer:

The correct answer is - When it contracts, it compresses the thorax and decreases its volume.

Explanation:

The diaphragm is a skin muscle that separates the stomach and chest and fits at the base of the chest and covers the lungs and thoracic cavity. The prime mover is the diaphragm as it is responsible for the major muscle during inhalation.

It flattens during inspiration by contracts and increases the chest cavity or thoracic cavity and increases the volume of the thorax and diminishes the pressure inside the lungs and air gets in the lungs.

PLSSS HELP a force of 3 × 104N exerted on an object with a mass of 15 tons. what magnitude of acceleration will the object undergo as a result of this force​

Answers

Answer:

Acceleration = 2 m/s²

Explanation:

Given the following data;

Mass = 15 tons to kilograms = 15 * 1000 = 15000 kilograms

Force = 3 * 10⁴ Newton

To find the magnitude of acceleration;

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

[tex] Acceleration = \frac {Force}{mass} [/tex]

Substituting into the formula, we have;

[tex] Acceleration = \frac {30000}{15000} [/tex]

Acceleration = 2 m/s²
