Answer:
Part A: The process of sexual reproduction is important because by this process organisms with varied genetic characteristics can be formed. Crossing over and independent assortment allow individuals to be born which are not alike to another and their parents. As a result, genetic diversity is produced.
Part B:
The process 1 is meiosis. The process 3 is development by mitosis.
The reproductive organs form sperm and egg by the process of meiosis. During this process, the number of chromosomes is reduced so that the number of chromosomes of an individual can be maintained.
The zygote converts into an embryo in a process called germinal development. The zygote replicates by mitosis to form into an embryo.
Answer:
Two cell divisions after DNA replication
Explanation:
After the DNA is replicated, the cell undergoes two rounds of meiosis to produce 4 cells, each wIth 23 chromosomes. This is how the cell goes from a diploid to a haploid state.
Answer:
Nocturnal animals are important pollinators. What niche do they specifically fill? They eat the nectars of angiosperm flowers.
Explanation:
Answer:
Genome mapping is used to identify and record the location of genes and the distances between genes on a chromosome. Genome mapping provided a critical starting point for the Human Genome Project. Sequenced DNA fragments can be aligned to the genome map to aid with the assembly of the genome.
By inducing mutations, scientists have been able to increase genetic variation, which breeders depend on to produce crops with desirable traits, such as resistance to diseases and insects. ... Mutations can be induced in a variety of ways, such as by exposure to ultraviolet or ionizing radiation or chemical mutagens.
Explanation:
Answer:
There are several reasons why it might be a good idea to write down your ideas and discoveries when you perform initial research on a topic. First, when you begin your research, you might get a lot of questions and doubts because you are not familiar with the topic. If you write these down, you are more likely to seek answers to these questions later on and gain a better understanding of them. Second, your initial ideas might not be all good, but they might lead you towards a good thesis. Writing them down ensures that these are not lost. Finally, by writing down your ideas and thoughts you actively engage with the subject, leading you to a better understanding of it.
