Additional observations were made on day 21, and no yellow-leaved seedlings were found alive in either dish. This is most likely
olga55 [171]

Answer: Inability to convert the light energy into chemical energy.

Explanation:

The above question relates to the issue regarding photosynthesis. Plants contain chlorophyll and this helps them in the conversion of the light energy that they get from the sunlight into a chemical energy.

In the case that no yellow-leaved seedlings were found alive in either dish, the reason for this will mainly be because the plant was not able to convert the light energy into chemical energy.

a diver with a mass of 60 Kg is standing on the top of a 10 meter high platform. what is the mechanical energy
inna [77]

Answer:

M.E = 5880 J

Explanation:

Given data:

Mass = 60 Kg

Height = 10 m

Mechanical energy = ?

Solution:

Formula:

M.E = K.F + P.E

K.E = 1/2 × mv²

P.E = mgh

Diver is not moving so K.E will be zero.

M.E = mgh

M.E = 60 kg × 9.8 m/s² ×  10 m

M.E = 5880 J  ( j= kg m²/s²)

What is the role of DNA ligase in the replication of the lagging strand during DNA replication? A. it unwinds the parental doubl
IrinaVladis [17]

Answer:

The correct answer is C. it joins Okazaki fragments together

Explanation:

During the DNA replication, the DNA is replicated by DNA polymerase and both the strand act as template strand. One strand is continuously synthesized by the DNA polymerase called the leading strand and the other strand is synthesized in a discontinuous manner called lagging strand.

In lagging strand due to discontinuous replication, many short nucleotide fragments are created which are called Okazaki fragments. These Okazaki fragments are joined by an enzyme DNA ligase. By making a bond between two Okazaki fragments it connects all fragments and makes a single daughter strand.

So the correct answer is C. it joins Okazaki fragments together.
