<span>Natural selection is when species learn to adapt to
their environment. They could (1) differential reproduction, that is, not all
organisms are able to reproduce to their fullest capacity because nature cannot
simply sustain it and (2) acquire genes, that is heredity. Certain
characteristics of organisms tend to survive if it continues to strive. If it
survives, this trait is passed down to the next generations forgetting the
other traits but only the one who could survive the environment. Therefore it
is true that <span>natural
selection is when ‘organisms inherit advantageous traits, and tend to reproduce
more successfully than other organisms’. One best example is the extinction of
other animals and some with the same species retains.</span></span>
Answer:
D. the homologous chromosomes are paired AND the spindle is formed
Explanation:
Meiosis is the type of cell division that results in four daughter cells with each having a reduced number of chromosomes (by half). Both meiosis and mitosis occur in different stages including prophase, metaphase, anaphase etc but meiosis occurs in two series of division processes called meiosis I and meiosis II.
In prophase I of meiosis, homologous chromosomes, which are similar but non-identical chromosomes from male and female parents pair to form tetrad or bivalent. This pairing of homologous chromosome is unique and peculiar to MEIOSIS but never mitosis.
Your missing some function/description.
Answer/Explanation:
Cytoplasm: [H] Jelly-like substance within the plasma membrane
Lysosome: [E] Sac filled with digestive chemicals
Mitochondria: [F] Structures that converts nutrients to energy
Centriole: [A} Structure that organizes motion of chromosomes
Endoplasmic reticulum: [G] passageways where chemicals are made
Vacuole: Sacs that store water, nutrients, or waste products
Cell membrane: [D] Membrane that surrounds and protects the cell
Nucleus: [J] Structure that contain DNA and regulates genes
Cytoskeleton: framework of protein fibers that guides organelle movement in the cell and help shapes the cell
Ribosome:[I] Structures that manufactures ribosomes
Nuclear membrane: [C] Membrane that protects the Nucleus
Golgi apparatus: [B] Stack of membranes that packages chemicals
Vesicle: [K] Package created by Golgi appaaratus
Nucleolus:[L] Small structure that synthesizes proteins
[RevyBreeze]
They create competition with some certain niche
The study of human interaction with the natural world over time is environmental history, emphasizing the active role that nature plays in influencing human affairs and vice versa. ... The first, nature itself and its change over time, includes human physical impact on the land, water, atmosphere, and biosphere of the Earth.
