List three conditions that would alter the activity of an enzyme. be specific with your explanation.

Three conditions (or inhibitors) will stop the enzyme's reaction from taking place. If another substance attaches to the site first the the reaction will not take place because the substrate can no longer attach to the active site. Conditions within the cell like temperature and acidity will also inhibit the reaction because it will change the shape of the active site which is very specific for the substrate that needs to attach to it. The enzyme will then become ineffective.

Every year a rice farmer collects his crops and burns the soil when he is done once the soil is enriched with debris he replants
brilliants [131]

Every year the farmer was taking care of his ice field, keep it clean and clear of all the unnecessary shrubs and then reuse the debris to fertile the soil again and then grow rice again. But since he fell sick, there is no one to take care of his rice field which will leads to the growth of unnecessary plants and weeds in it.

There will grow wild plants and shrubs which will contaminate the rice field.

A food shows many food chains within a community and how they overlap.
3241004551 [841]

Answer:

The food chain describes who eats whom in the wild. Every living thing—from one-celled algaeto giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.

For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.

Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.

Contrast the genetic content and the origin of sister versus nonsister chromatids during their earliest appearance in prophase I
Bogdan [553]

Answer:

<u>Sister chromatids are identical  forms of chromatids  of a chromosomes. They are mostly  formed by semi-conservative replication of DNA molecule of a single  chromosome.Thus they  are  like  </u><u>'photocopies' </u><u> of  original parent  chromosomes; joined together at the Centromere</u>.

They are exactly similar in all ramification; with the same gene and allele compositions..

<u>However; slight differences  arise between the two identical sisters due to  </u><u>mutation</u><u> from</u><u> errors </u><u>at replication;and also in  the  length of telomere repeats.</u>

Non-sister chromatids are dissimilar forms of  chromatids of a chromosomes formed  when each half of  a chromosome  at fertilisation from separate   haploid sex-cells, of each parent. fused.They contain different genetic composition;because  they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.

<u>However, they are genetically  similar in composition; if they  are contained in homologous chromosomes</u>. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by  chromosomal crossing-over between the non-sister chromatids  on the chromosomes ; therefore identical genetic characteristics are shared .
