Modifications of genes in sex cells
Answer:
the sun shines on earth, which through photosynthesis in a humble blade of grass turns into food and energy for the grass. now a small mouse hops along, stomach growling. it eats our blade of grass now itself getting energy. the naive, full mouse hops through the field before it squeaks in horror. a snake slinks towards it. the mouse is too slow. and the mouse breathes his last breath. the snake swallows it whole. stomach content now digesting its new energy sleeps. before it has the chance to react a hawk snatches it up in her claws. killing it she eats. this snake is poisonous, the next time our hawk flies, she stumbles, then falls. vanquished by poison her lifeless body lies in the dirt. her nutrients go into the soil, thanks to decomposers like worms. her nutrients help new grass blades grow, and the cycle continues.
I hope this helps u!
Pls give brainliest(had 40 down to 2 for no reason and worked long) and a thx ;)
I will thank u via profile thanks and comments
Enzymes are catalysts that can be used more than once. If a substance needs to get broken down then it can use the corresponding enzyme to attach itself and break it down into simpler substances. After this is gone, the next substance might come up and attach itself to the enzyme like a lock-and-key model.
Therefore the answer is A) Enzymes accelerate chemical reactions without getting used up in the process.
Answer:
The correct answer is given below:
Explanation:
1. A cleavage furrow or cell plate forms, separating the nuclei - Cytokinesis. During cell division, after division of nucleus, cytoplasm divides by furrow in an animal cells and by cell plate formation in the plant cells.
2. Chromosomes line up at the equator and chromatids are attached to spindle fibres—Metaphase. During metaphase all the chromosomes get arranged on the equatorial plane or the central plane
3. Nuclear membrane and nucleolus reappear- Telophase. The nuclear membrane starts to form around each of the daughter chromosomes and nucleolus also reappears in the daughter nuclei.
4. Genetic material replicates and is joined at the centromere- S-phase of the interphase. Duplication or copying of the DNA occurs in this phase
5. Centromeres divide and single-stranded chromosomes move to the poles- Anaphase. During anaphase, the sister chromatids of each chromosome gets separated and move to the opposite poles.
