The sodium and potassium ions are transported using a sodium potassium pump the process of moving sodium and potassium ions across the cell membrane.
Answer:
e
Explanation:
The correct answer would be that they <u>are more numerous than primary consumers.</u>
Secondary consumers are never more numerous than primary consumers. <em>This is primarily due to the fact that the higher we move up the food chain, the less efficient the amount of energy derived from food. Up to 90% of energy is sometimes lost at each trophic level as we up. Due to this inefficiency, the available food at top consumer levels can only support a few organisms. Hence, the higher we move up the food chain, the lesser the number of organisms the available food can support.</em>
The correct option is e.
To produce the recessive phenotype both parents must be heterozygous for the dominant phenotype!!
Answer:
Question 1. The steps occur in the following order:
INTERPHASE
1. G1
2. S
3. G2
MEIOSIS I
4. Prophase 1
5. Metaphase 1
6. Anaphase 1
7. Telophase 1
8. First Cytokinesis
MEIOSIS II
9. Prophase 2
10. Metaphase 2
11. Anaphase 2
12. Telophase 2
13. Second cytokinesis
Question 2
Sister chromatids are created here (interphase)
The 2 X chromosomes pair (prophase 1)
A cell exists with one X chromosome that has 2 attached sisters (prophase 1)
An X chromosome appears in which the 2 sisters have different alleles (prophase 1)
2 X chromosome sisters move in opposite directions on the spindle (anaphase1)
Explanation:
During interphase the cell prepares to divide. During meiosis 1 Homologous chromosomes are segregated and the ploidia is reduced from diploid to haploid in a reductive division where the sister chromatids are held together. Unlike meiosis I, meiosis II is an "equational" division analogous to mitosis where sister chromatids are secreted creating four haploid cells.
