Why can only somatic cells go through mitosis? Why are somatic cells diploid? Why do gametes undergo meiosis? Why does meiosis start with a diploid cell? Why do somatic cells divide by mitosis? Why must DNA be packaged into chromosomes before mitosis or meiosis can occur? Why does meios...
Why is it important that cells produced after meiosis be diverse?Question:Why is it important that cells produced after meiosis be diverse?Genetic Variation and Natural Selection:In order for Darwin's theory of natural selection to occur, the population must contain a diverse set of genetic t...
Sexual reproduction ensuresthat there is high degree of variation within populations. The parent organisms give rise to reproductive cells called gametes. These are formed by a special type of cell division called meiosis. The cells produced in this way has half the normal amount of genetic materia...
To earn this badge, learners must complete Module 6, scoring a B or better (85%) on the module test. This badge demonstrates proficiency in these learning objectives: Describe how cells get energy describe the structure of ATP and its role in the cell energy cycle (ATP cycle) ...
one genome from each of the parental species, and this may mess up the normal process of meiosis that forms sperm and eggs. If it gets messed up in hybrids that, without fertilization, eggs can go on to develop into adults (and these eggs must still have two genomes), we have parthenog...
For most of these critters you’d have to carefully explain basic stuff like “what goes up must come down”, “the sky is blue”, “fire is hot”, “water is wet”, etc. It’s no coincidence that minds are great at handling the environment they find ...
One of the reasons cancer is so difficult to treat is because the disease evolves through natural selection to grow more resistant to treatments. Sexual Selection Natural selection doesn’t just apply to climate, food, and predators. Members of a species that sexually reproduce must compete with ...
Answer to: For fertilization to take place, why must sexual intercourse take place in the period that starts two days before and ends one day after...
All living things must reproduce to carry on their species. There are two main ways organisms can do this, sexual or asexual reproduction. In sexual reproduction, organisms combine gametes, or sperm and egg cells, to create a new organism. In asexual reproduction, one organism divides and ...
Why must DNA be packed into chromosomes before mitosis can occur? Why does synapsis occur in meiosis and not mitosis? Why do somatic cells divide by mitosis? Why can only somatic cells go through mitosis? Why do chromosomes condense during prophase?
