Answer:
A. 1.2
Explanation:
Normally, a human body cell contains 46 chromosomes - 23 inherited from the father and the same number from the mother.
Most of the human DNA, or human genes, are located in the chromosomes.
Each metaphase chromosome consists of:
two sister chromatids containing one DNA molecule each, and since they are formed by replication, these molecules are completely identical in gene content; that is why chromatids are called sister chromatids; two centromeres, one on each chromatid.
Answer:
c. Retrograde motion of the planets as they moved across the sky.
Explanation:
Ancient Greek philosophers were extremely intelligent people who propounded some ideas that have helped shape science to what it is today.
They had evidence for the spherical shape of the earth, the link between lunar phases and oceanic tides, and the existence of exoplanets, however, they did not have evidence for the retrograde motion of the planets as they moved across the sky because they believed that if the Earth moved around the Sun, then they would be able to see the stars from divergent points along Earth's orbit.
False. Genetic engineering involves genes and specific traits.
Answer:
Deoxyribonucleic Acid (DNA)
Explanation:
DNA is the chemical name for the molecule that carries genetic instructions in all living things.
It helps because say the hinge joint had a structure as one of a ball-and-socket joint the knee (where the hinge joint is located) wouldn't bend it would rotate/ spin like our shoulders. This is how classifying joints according to their structure and function can/ may help describe human movement.
