Flauer [41]2 years ago
4 0

Answer:

Totipotent Stem Cells - They can differentiate into any type of human body cell or the placenta.

Example: Fertilized egg cells.

Pluripotent Stem Cells are from totipotent cells and can differentiate into any cell in the human body; however, not many are in the placenta.

Example: Blastocyst cells.

Multipotent Stem Cells - They can only differentiate into closely related cells.

Example: Blood stem cell

Unipotent Stem Cells - They can only produce their type of cell.

Example: Skin stem cells (which can only become a new skin stem cell).

An object with a kinetic energy of 200 J and Potential energy of 300 J, has a mechanical energy of what?
True [87]

Answer:

500 J

Explanation:

Emechanical=U+K,i.e., the mechanical energy Emechanical is the sum of the potential energy U and kinetic energy K.

So, the object has a mechanical energy of 200+300=500 J.

What group of organisms are responsible for capturing energy within ecosystems
Marina86 [1]

The type of organisms that take energy by eating up other organisms in an ecosystem are called 'CONSUMERS'. Now these consumers are further divided into three major classes:

1. Primary consumers: this type of consumers feed directly from the producers (plants) and they only eat grass, leaves, vegetables, etc. Such animals are also called herbivores. Example: rabbit

2. Secondary consumers: these are the animals that eat up primary consumers (animals that feed only on plants). These animals are called carnivores. Example: snake

3. Tertiary consumers: animals that eat carnivores which eats a herbivore are called tertiary consumers. They can be completely carnivore or omnivore (who feed on animals and plants both). Example: humans (they feed on animals and plants both)

Given a force of 56 n and an acceleration of 7 m\s2, what is the mass
nirvana33 [79]
<span>56 n/ 7 m/s^2 = 8kg

Example:
To solve this given word problem we can first identify the given and the apt formula to use in this phenomenon: Given: Force = 4, 500 N = 4, 500 kg-m/s^2 Acceleration = 5 m/s^2   </span>
<span>Formula: f=ma </span>
<span>Derivation: m = f/a </span>
<span>Solution: </span><span><span>
1.    </span>M = f/a</span> <span><span>
2.    </span>M = 4,500 kg-m/s^2 / 5 m/s^2</span> <span><span>
3.    </span>M = 900 kg  </span> 

<span>Hence, the object’s mass is </span>900 kg.<span>
