Linked genes are genes that are likely to be inherited together because they are physically close to one another on the same chromosome. During meiosis, chromosomes are recombined, resulting in gene swaps between homologous chromosomes.
Answer:
Tropomysin, calcium
Explanation:
Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.
Muscle will only contract when they get a rush of calcium ions.
The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.
Answer:
Carbohydrates: pasta and rice, both very starchy
Lipids: beef and bacon, both have animal fat in themm which contains lipids
proteins: eggs and beef, lots of animal derived foods contain proteins since thy are the basis of life.
Explanation:
Answer:
The independent variable of Galileo Galilei experiment is
1) the speed of the ball
Explanation:
Galileo Galilei (1564- 1642) was one of the foremost scientist to carefully consider what was going on.
One of the key ideas is that everything depends on time (t) so it plays the role usually assigned to ' x ' in the Cartesian setup and is recorded horizontally .
Galileo experiment proves that objects fell with the same acceleration
Humans are diploid organisms that have 23
pairs of chromosomes (or 46 chromosomes) in
all somatic or body cells. These cells divide by
mitosis that forms daughter cells with same
number of chromosome pairs as present in
parent cell.
In humans, gametes (eggs and sperms) are
formed from the germ cells by the process of
meiosis that leads to reduction of chromosomes
in daughter cells (with half the number of
chromosomes as present in parent cell).
Thus, the correct options are:
-bone cell has 46 chromosomes, as bone is a
somatic cell.
-Skin cell has 23 chromosome pairs (46
chromosomes), as skin cell is somatic cell.
-gamete has half the chromosomes (23
chromosomes) of a red blood cell (46
chromosomes) as red blood cell is somatic cell.
