The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Meiosis is a cell division which results in the reduction of chromosome number by half (from diploid to haploid) in daughter cells. It consists of meiosis I and meiosis II.
In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicates which are present as pairs of sister chromatids. When comes to separation, homologous chromosomes separates only, but not sister chromatids. Homologous chromosomes are present only in meiosis I.
In anaphase II, since the cell is haploid, there are 23 chromosomes in duplicates, which are present as sister chromatids. So, in this phase, sister chromatids are those who separates.
Answer:
Regions of the digestive system can be divided into two main parts: the alimentary tract and accessory organs.
Explanation:
Answer:
The correct answer is a. anaerobic metabolism.
Explanation:
Anaerobic metabolism refers to a high intensity of exercise in which the absence of oxygen limits performance due to the accumulation of metabolites and the corresponding metabolic and physiological dysregulation.Predominantly anaerobic exercises are characterized by: high intensity and short duration, energy is obtained from immediate sources such as muscle ATP, phosphocreatine (PC) and glucose and does not need oxygen for this. For very explosive or high intensity movements it is necessary to obtain a powerful and fast energy, this is obtained by anaerobic systems. The anaerobic metabolism is able to respond immediately to the energy demands of physical exercise and can provide energy for very high intensity exercises (strength and / or power). But this system has a limited capacity, it is short-lived, so if the exercise continues, either you have to stop due to fatigue or reduce its intensity (the power developed) to a level where energy can be obtained through the aerobic metabolism.

Explanation:
Answer:
Hairy skin which helps kakapo's ancestors to live in harsh climate of New Zealand.
Explanation:
New Zealand's early ecology greatly affected the population of kakapo's ancestors because the environmental conditions for kakapo's ancestors are favourable and there is no invasive species which reduces the population of kakapo's ancestors near to extinction. The traits that were selected for the kakapo's ancestors provides ability to live and survive in the temperate and subtropical climates of New Zealand. The flightless trait in this bird is also responsible for its extinction because this bird can't run away from their predators.
