What is not characteristic of primitive mammals?

Biology
2 answers:
denis-greek [22]3 years ago
4 0

The correct answer is - B. feathered.

The primitive mammals were very small (with a couple of exceptions), rodent-like, also very often described as shrew-like. They were feeding with plants, as well as with insects and the occasional egg. Most of them were night creatures, and they were living in the shadow of the much bigger dinosaurs.

So, they were small, furry, rodent-like, night-dwellers, but there isn't a single evidence that any of the primitive mammals, or any mammal whatsoever, had feathers.

<h3>What is carbohydrate?</h3>

The carbohydrate is one of the six classes of food.  The six classes of food that we have are;  fat, carbohydrates, protein, vitamins, minerals and water. Carbohydrates are made up of glucose molecules as it is a macromolecule.

These molecules are eaten for the purpose of energy because they are broken down in the body to give glucose which is a source of energy in the body.

Thus, the food that is not a good source of complex carbohydrates is milk.

According the law of Inertia _____.
kobusy [5.1K]

Answer:

Law of inertia, also known as Newton’s first law of motion states that An object will continue to be in the state of rest or in a state of motion unless an external force acts on it. We have read about the Aristotle fallacy, as per which an external force is always required to keep a body in motion.

Explanation:

Galileo’s Free Fall Experiment

The most accepted theory of motion in Western philosophy, prior to the Renaissance, was the Aristotelian theory which stated that “In the absence of external power, all objects would come to rest that moving objects only continue to move so long as there is a power inducing them to do so. ” Despite its general acceptance, the Aristotelian theory was discredited by several notable philosophers. Later, Galileo refined the theory of inertia.

How did Galileo Explain Inertia?

Galileo hypothesized that a falling object gains an equal amount of velocity in equal intervals of time. This also means that the speed increases at a constant rate as it falls. But, there was a problem in testing this hypothesis: it was impossible for Galileo to observe the object’s free-falling motion and at the time, technology was unable to record such high speeds. As a result, Galileo attempted to decelerate its motion by replacing the falling object with a ball rolling down an inclined plane. Since free-falling is basically equivalent to a completely vertical ramp, he assumed that a ball rolling down a ramp would speed up in the exact same way as a falling ball would.

Using a water clock, Galileo measured the time it took for the rolling ball to reach a known distance down the inclined plane. After several trials, it was observed that the time it took for the ball to roll the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance. In short, if you were to double the amount of distance the ball traveled, it would travel four times as far. Through this experiment, Galileo concluded that

If an object is released from rest and gains speed at a steady rate (as it would in free-fall or when rolling down an inclined plane), then the total distance, s, traveled by the object is proportional to the time squared needed for that travel.

Three-carbon molecules of PGA are converted to G3P small sugar molecules by _____, which come from the light reaction.
anyanavicka [17]
<h3><u>Answer;</u></h3>

<em>ATP and NADPH</em>

<h3><u>Explanation;</u></h3>

Three-carbon molecules of PGA are converted to G3P small sugar molecules by <em><u>ATP and NADPH</u></em>, which come from the light reaction.

  • <em><u>Photosynthesis</u></em>, a process in which green plants use energy from the sun to make their own food, involves two types of reactions, light reactions in light stage and light independent reactions in dark stage.
  • During <em><u>the light reactions ATP and NADH are generated from the electron transport chains</u></em>, which are then taken to the second stage (light independent stage) of photosynthesis. During the Light independent stage the energy stored in ATP and NADH is <em><u>used to convert 3-carbon PGA to G3P</u></em>.
