1. How much force accelerate a bicycle and rider with mass 60 kg at 1.5 m/s?

NISA [10]

Answer:

Force, F = 90 N

Explanation:

Given that,

Mass of the bicycle and rider, m = 60 kg

Acceleration of the bicycle and rider, a = 1.5 m/s²

We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :

F = ma

F = 60 kg × 1.5 m/s²

F = 90 N

So, the force acting on the bicycle and rider is 90 N.

The trp and lac operons are regulated in various ways. How do bacteria regulate transcription of these operons? Sort the stateme

OLEGan [10]

Answer:

Operon is not transcribed:

-lac operon: lactose absent

-trp operon: tryptophan present

Operon is transcribed, but not sped up through positive control:

-lac operon: lactose and glucose present

-trp operon: tryptophan absent

Operon is transcribed quickly through positive control:

-lac operon: lactose present, glucose not

Explanation:

The trp operon is controlled via negative control only.

Presence of tryptophan will inhibit the transcription of the operon genes

The lac operon is controlled via negative control and positive control.

●Negative control:

--Transcription is turned off due to

active Repressor protein and absence of lactose

--Transcription is turned on due to

Inactive Repressor protein and presence of lactose

●Positive control:

--Transcription rate is higher due to absence of transcription and presence of lactose as a regulatory protein (CAP) adhere to the lac operon promoter

What can be said about the diversity of life in the high tide zone compared to that of the low tide zone?

Airida [17]

Answer:

B. There is less biodiversity in the high tide zone because the tidal changes make survival difficult.

Explanation:

The high tide and low tide zones are located on the seashore as the ocean water merges with land.

High tide zones are usually covered with water during high ocean tide while low tide zones are always submerged in water.

There is low biodiversity in the high tide zone because the tide here changes rapidly and organisms find it difficult to adapt. Organisms that inhabit here must be welll adapted to withstand peroids of high tides.
