8 0

Answer:

335 million years ago

Explanation:

Pangaea or Pangea ( /pænˈdʒiːə/) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 335 million years ago, and began to break apart about 175 million years ago.

Drag the terms on the left to the appropriate blanks on the right to complete the sentences. resethelp biomass assimilated feces
yaroslaw [1]

1. The right answer is not assimilated

The assimilation designates in biology the process by which substances and materials external to the body are transformed into substances and materials interior to the body.

2.  The right answer is feces.

Feces correspond to the residue of digestion that the intestine could not absorb. They consist of 80% water and 20% dry matter (intestinal cell debris, bacteria, cellulose that comes from the non-absorbable part of plants).

3. The right answer is assimilated  

The opposite of the first one.

4. The right answer is cellular respiration.

Cellular respiration is the process of cellular metabolism that converts the chemical energy contained in nutrients into ATP (adenosine triphosphate).

5. The right answer is assimilated

"Assimilation" can be also used for energy.

6. The right answer is biomass

In the field of energy, biomass is the organic matter of plant origin (microalgae included), animal, bacterial or fungal (fungi), usable as a source of energy.

7. The right answer is biosynthesis.

Biosynthesis consists of a formation and production of a chemical compound body by a living organism, usually due to the catalysis of an enzyme. For example, protein synthesis is the synthesis of organic substances by an organism. Chemosynthesis and photosynthesis are biosynthesis.

8. The right answer is non assimilated.

Since it is lost, so it is not assimilated by the organism.

9. The right answer is biosynthesis.

In ecology, the trophic level is the rank occupied by a living being in a food web. It is measured in some way by the distance separating this being from the basic level which is that of the primary autotrophic production.

Above this basic level, each link (or stage) of a food chain corresponds to a trophic level.

Hormone is controlled by a
Marina CMI [18]

Answer:

Hormones are controlled by a

(negative)

feedback system between the glands that produce this hormone and the  concentration of blood calcium ions. If the level of ions is

(low)

,hormone secretion is increased. This causes  resorption by  cells called

which releases both calcium and phosphate ions into the blood stream.​

Explanation:

Negative Feedback a the process in your body that helps to maintain Homeostasis. If some variable changes a value in your body, like your ion levels,  your glands produce a hormone that causes resorption by  cells. This releases both calcium and phosphate ions into the blood stream and therefore your ion levels go back to normal.

Hope this helps!

7. What is the kinetic energy of a 3-kilogram ball that is rolling at 2 meters per second?
nydimaria [60]
Kinetic energy = 0.5*M*V^2 

 Q7-
 
0.5*3*(2^2)= 6J

Q8a- 

0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J 
the second ball has more kinetic energy.

Q8b-

at the max height, all the kinetic energy is converted to potential energy, 

gravitational potential energy is = M*g*h

that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:

First ball:
2kg*9.81(g)*10m = 196.2J

Second ball
4kg*9.81*10m= 392.4J

The second ball has more potential energy

When the plaintiff assumes responsibility for injury, or in other words, he or she agrees to participate when there is a chance
inysia [295]

Answer:

True

Explanation:

Assumption of risk is a defense in the rule of offences, which bars or decreases a plaintiff's right to retrieval in contradiction of a inattentive tort feasor if the offender can prove that the plaintiff willingly and meaningfully expected the hazards at subject inherent to the unsafe action in which the plaintiff was contributing. The most shared specimen is a waiver of obligation employed earlier contributing in a hazardous action. Frequently at matter in belongings where the respondent gifts an rapid statement of the danger defense is whether the plaintiff decided to assume the risk of the specific harm that happened.
