Answer:
1. homologous.
2. Meiosis
3. Human sex cells do have 23 chromosomes, but not these 23. ... None, egg cells don't have chromosomes. No, sex cells do have chromosomes. Meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes one homolog of each pair. This is the haploid number.
Well the endoplasmic reticulum has both smooth and rough bodies. Smooth is the synthesis of fats and detoxifies harmful bodies. Mostly in the liver. And the rough mainly synthesize proteins which are basic components of life. Proteins are sent all over the body and are used for many functions. The golgi is used to package those proteins and send those proteins through the body. Mitochondria creates energy and is the power house of the cell. And the plasma membrane is like the gate keeper. Decides what can enter it exit the cell and prevents harmful things from coming in. Allows proteins to leave.
Answer:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
Your answers are D increase in deforestation, F rising sea levels, and E increasing use of fossil fuels.
Cytoplasm!
hope this helps! :)
