Answer:
An object's <u>mass</u> will remain constant throughout the universe, but it's <u>weight </u>can change from planet to planet. If you increase the mass of a planet, what happens to its gravity? <u>Strength of Gravity increases.</u> If the gravity on a planet decreases, what happens to the weight of an object on that planet? <u>Weight Decreases</u>
Explanation:
Answer:
The statement that is correct is that all cells have the same genes, but different genes are active in different cells.
Explanation:
Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.
Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.
All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. <u>There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation</u>.
The other choices are wrong because:
- <em>The eyes look different from the liver, because they have the same genes, but only some are expressed.
</em>
- <em>Differentiated cells and tissues do not lose their genes.
</em>
- <em>All cells have DNA.</em>
Answer:
1) Accommodation is the process of changing the shape of the lens to focus on near or distant objects.
- <em>To focus on a near object</em> – the lens becomes thicker, this allows the light rays to refract (bend) more strongly.
- <em>To focus on a distant object </em>– the lens is pulled thin, this allows the light rays to refract slightly.
2) - i don't know. im so sorry -
