1. They respond to events occurring inside a cell.
External Regulators Proteins:
External Regulators Proteins that respond to events outside the cell are called external regulators. External regulators direct cells to speed up or slow down the cell cycle.Growth factors are among the most important external regulators.They stimulate the growth and division of cells.The three types of external regulators proteins are Cyclins, cyclin-dependent kinases (Cdks), and the APC/C.Therefore, the statement that NOT describe external regulatory proteins is Statement 1.

Answer: the possible possibilities are 3 if u have an A and B type of antibodies.
Explanation:
it can be -- AO or AB or BO
plus factor will depend upon enzyme presence.
If a person is having both anti-A and anti-B antibodies in blood then the possible blood group of that individual can be O. However, Rh factor cannot be determined by this information.
What is Blood Group?Blood grouping is the system of classification of blood on the basis of antibodies and antigens in blood which are inherited substances present on the surface of the red blood cells.
Blood groups are classified into four types. These are A, B, AB and O. Blood group A has antigens A on the RBCs with anti-B antibodies present in the plasma. Blood group B has B antigens on RBCs with anti-A antibodies in the plasma. Blood group O has no antigens on the membrane of RBCs and antibodies of both types anti-A and anti-B antibodies in the plasma. Blood group AB has both A and B antigens, but no antibodies in the plasma.

D. Earth's changing speed and direction
Answers
Answer: A. the gravitational pull of the Sun
The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.

How can you tell the difference between alternate and opposite leaf arrangements?
They are based on based whether the leaf pinnate or palmate venation.
They are based on based whether the leaf has one or two leaves at the node.
They are based on based whether the leaf has a smooth or toothed margin.
They are based on whether the leaf is simple or compound.
Answers
Answer:
They are based on based whether the leaf has one or two leaves at the node.
Explanation:
Answer: They are based on based whether the leaf has one or two leaves at the node.
Explanation: You can tell the difference between alternate and opposite leaf arrangements based on whether the leaf has one or two leaves at the node. Alternate leaf arrangement is when a single leaf is attached at one location on the stem, the node, in an alternating pattern. On the other hand, the opposite leaf arrangement is when two leaves are attached to the same node on opposite sides of the stem.

Importance of mitosis, two reasons and 300 words.
Answers
Answer: Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
1. Development and growth
After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis. This growth continues throughout an organism’s life, in plants, animals, and fungi. In this way, the original chromosomal set is preserved.
2. Cell replacement
This occurs when the original cell is damaged or wounded. New cells are created to replace those that were damaged. Examples of this are the healing of a cut or a broken bone. When old cells die, new ones replace them to ensure continuing functionality.
3. Asexual reproduction
Single-celled organisms and certain multicellular organisms use mitosis for asexual reproduction. This includes reproduction by fragmentation, as in the case of planaria, and reproduction by budding, as in the case of sea anemones. Many plants reproduce using mitosis.
First, we need to understand what meiosis is. Meiosis is the replication of cells that results in each daughter nucleus containing half of the parent cell’s chromosomes. Meiosis is used primarily for the production of gametes, which are incorporated in sexual reproduction. Thus, the main difference between mitosis and meiosis is that mitosis produces somatic (body) cells, which can go on to become part of any bodily tissue, whereas meiosis only produces germ (sex) cells. Organisms which reproduce asexually cannot undergo meiosis, whereas all eukaryotic organisms undergo mitosis. Mitosis and meiosis are similar in that both can only occur in eukaryotic cells. This is because prokaryotic cells do not contain a nucleus within which to begin the processes of mitosis and meiosis. Instead, prokaryotes replicate themselves using binary fission. Both mitosis and meiosis begin with DNA replication in the parent cell to create four sets of chromosomes: in mitosis, these sets are split to form two diploid daughter cells, while in meiosis, these sets are split to form four haploid daughter cells. This is because cells undergo only one division in mitosis, whereas they undergo two divisions in meiosis.
