Answer:
prophase 1 and metaphase
Explanation:
:)
Crossing over of chromosomes takes place in the Prophase I phase of meiosis. This process, crucial for genetic diversity, involves the exchange of genetic material between paired homologous chromosomes.
Crossing over of chromosomes occurs during the Prophase I phase of meiosis. This process is critical for the generation of genetic diversity as it allows the exchange of genetic material between homologous chromosomes. During crossing over, homologous chromosomes pair up and exchange segments of their DNA. This results in chromosomes that have a mix of genes from both parents, producing unique combinations of traits in offspring.

B: invasive species
C: climate change
D: pollution
Answer:
D - growth, repair, and reproduction of cells
Explanation:
An Overview of the Cell Cycle. The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. These processes define the two major phases of the cell cycle.
Factors Affecting Enzyme Activity. ... Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

Linked genes are those that are found on the same chromosome and are typically inherited together due to their close proximity. This concept is crucial to understanding how certain traits are passed from parents to offspring.
Genes that are linked together are generally found on a particular chromosome. The term 'linked' refers to the propensity of genes to be inherited together because of their location on the same chromosome.
For instance, the genes for eye color and hair color may be linked on the same chromosome. Therefore, variants of these characteristics are often inherited together, dictating that offspring may have a combination of traits from one parent.
It's important to note that some genes may also recombine during the process of meiosis, which can result in offspring with variations of traits. However, linked genes are less likely to be separated during this process due to their physical proximity on the chromosome.
