Answer:
Scientists did not know how traits were inherited
Explanation:
Scientist before did not know how the trait is passed on not until Griffith's experiment.
Since enzymes function as organic catalysts, a cell would not be able achieve homeostasis if the required enzymes were not present.
The type of front that is represented by this cross section is the occluded
<h3>What kind of front is an occluded front?</h3>
A warm air mass pushes on a cooler air mass (the warm front) and then another cold air mass pushes on the warmer air mass (the cold front). As cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front.
With this information, we can conclude that the type of front that is represented by this cross section is the occluded.

Answer:
This question lacks options, the options are:
A. Halved
B. Doubled (x2)
C. Quadrupled (x4)
D. Octupled (x8)
The answer is B.
Explanation:
Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).
However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
The colors for the stars are red, white, blue-white, white, and blue, and their temperature are 3,910 K, 3,500 K, 25,200 K, 22,400K, 5,780K, 9,600 K.
<h3>What is a star?</h3>
A star is a type of celestial body that can be set apart from others because it shines due to inner radiation. Moreover, stars are classified by:
- Color
- Size
- Location
- Temperature
- Age
Now, let's identify the color and temperature of the stars:
- Aldebaran: This star has a temperature of 3,910 K and its color is red.
- Betelgeuse: This star has a temperature of 3,500 K and its color is red.
- Sirius B: This star has a temperature of 25,200 K and its color is white.
- Spica: This star has a temperature of 22,400K and it is a blue-white star.
- The Sun: This star has a temperature of 5,780K and its color is white.
- Vega: This star has a temperature of 9,600 K and it is a blue star.
