Do chromosome mutations occur during nuclear division

Biology
1 answer:
Yuliya22 [10]4 years ago
4 0
 <span>In general mutations often occur during nuclear division because each chromosome has to replicate before division (mitosis). During replication your 3 billion nucleotides make copies of themselves leaving one copy in the original cell and another in the sister cell after division. This as you can imagine makes mutations most likely to occur here.

Shtirlitz [24]
When Barney was giving his speech and discussing each slide he was only giving definitions, symptoms, risks associated with the animal-borne diseases and treatment. This was not an effective strategy for Barney or for his class/listeners. Barney should have given pictures along with the slides so that everyone could see what the diseases looked like. Pictures also help people to have a better understanding of what they are learning/hearing.

Cell wall - supports the cell by giving it strength and shape made of cellulose

Golgi body -  processes and bundles macromolecules like proteins and lipids as they are synthesized within the cell

er  - a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins

Answer:

The correct answer is -

1.1 A. herbivore - greenfly

b. producer - rose

1.2. 1 kJ/m2/year

1.3 rose plants will increase, ladybirds will decrease, blackbirds will decrease.

Explanation:

In this food chain,

Rose >>Greenfly >>Ladybird >>Blackbird

Rose plants are the producers as they generate their food and energy and does not depend on other organisms where as greenfly are the primary consumer or herbivore as they depend on the rose plant for their food and energy only, however, ladybird as secondary consumer and blackbird as tertiary consumer depend on greenfly and ladybird respectively.

If rose plants have 1000 kJ/m2 /year of energy and as it is known that only 10% moves to the next tropic level then blackbird would have:

rose = 1000

greenfly = 1000*10/100= 100 kJ

ladybird = 100*10/100 = 10kJ

blackbird = 10*10/100 = 1 kJ

If greenfly removes from here the rose plant will increase as these depends and eat rose plants and lady bird will decrease as these are the primary source of food for lady bird and if ladybird decrease blackbird also decrease.
