Answer:
The second time the daughters cells divided haploid cells form and then migrate to other haploid cells in the process of fertilization.
Explanation:
Daughter cells divide a second time In meiosis because it creates cells that are destined to become gametes.
What is Meiosis?This is the type of cell division common in reproduction and gamete production and produces four unique daughter cells.
The daughter cells divide twice because it creates cells that are destined to become gametes as its union during fertilization would result in offspring with twice the normal number of chromosomes.

One challenge to understanding Earth's geologic history is
Most ancient ocean plates have been destroyed by subduction
Plate tectonics causes uplifting
Continents collide and destroy fossil evidence
There are few continental plates older than 200 million years old
Answer:
Continents collide and destroy fossil evidence
Explanation:
One main challenge in understanding earth's geologic history is that continents collide and destroy fossil evidence.
Fossils are the preserved remains of dead organisms found in rocks. They are very good and useful indicators of the life of an organism. By studying the progression of their evolution, a vivid understanding of the earth's geologic history can be constructed.The earth revolves ____ around the sun each year when viewed from above the North Pole

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.
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.

4. Which is a factor that keeps Earth in orbit around
the Sun?
A. the gravitational pull of the Sun
B. the orbital path of the moon
C. the continuous motion of the universe
D. Earth's changing speed and direction
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.

Which of the following anatomical directions are opposites?
A. Anterior and posterior
B. Posterior and superior
C. Anterior and superior
D. Posterior and inferior
The anatomical directions that are opposites of each other are: Option D. Posterior and inferior . Anatomical directions refer to a standard frame of reference used to describe the locations and orientation of body structures.
The following anatomical directions are opposites of each other:Anterior (front) and posterior (back): These are opposites and refer to the front and back sides of the body. The front side of the body is the anterior side, whereas the back side of the body is the posterior side.
Superior (upper) and inferior (lower): These are opposites and refer to the upper and lower portions of the body. The upper side of the body is the superior side, whereas the lower side of the body is the inferior side. Medial (towards the midline) and lateral (away from the midline):
These are opposites and refer to the sides of the body. The side of the body that is closer to the midline is the medial side, whereas the side of the body that is further away from the midline is the lateral side. Proximal (closer to the trunk) and distal (further away from the trunk):
These are opposites and refer to the position of limbs or body parts relative to the trunk. The part of the limb or body that is closer to the trunk is the proximal part, whereas the part of the limb or body that is further away from the trunk is the distal part. Option D is correct.

Read the information for transcription and then answer the question.
Protein Synthesis
Explain the process of transcription
Answer:
Protein synthesis is the process which synthesizes proteins by the information coded in the DNA molecule with the help of two distinct process takes place in order namely transcription and translation.
Transcription is the first process of the central dogma or the protein synthesis that produces mRNA molecule that carries all the information stored in the DNA molecule out of the nucleus (in eukaryotes only) to the ribosome where the second process Translation takes place.
Untwists then unzips of DNA molecule is catalyzed by RNA polymerase result in the Hydrogen-bonds between the strands break .
Creates complementary base pairs with bases of the DNA strand with help of free RNA nucleotides
weak hydrogen bonds and sugar-phosphate bonds form between base pairs and RNA nucleotides respectively
mRNA strand is synthesized and peels off the DNA and transported or pass from the nucleus to cytoplasm

2. Which blood type would you have if antibodies A and B were made during your first year of life?
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.
