Answer:
a. a plant cell undergoing cytokinesis
Explanation:
Cytokinesis is the process where the cytoplasm divides after mitosis to form two different daughter cells from the parent cell. Animal cell divides by just a cleavage formation. Plant cells have an additional step of formation of cell plate because they have cell wall.
At the end of anaphase and beginning of telophase when the two new daughter nuclei have just formed, cell plat formation begins. Secretory vesicles from golgi body come at equator of the dividing parent cell. These vesicles release all the materials required for cell wall formation. The materials start to form the cell plate which moves outwards till it reaches the division site of parent cell wall. Slowly cell wall arises from cell plate and cytokinesis occurs giving rise to new plant cells.
Answer:
flexion - depression
extension - elevation
adduction - medial rotation
abduction - lateral rotation
Explanation:
Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.
Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.
Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.
Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.
Answer:
The Adenosine triphosphate (ATP) molecule is the nucleotide known in biochemistry as the "molecular currency" of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells. Energy is released by hydrolysis of the third phosphate group. ...
Explanation:
ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
The answer is true.............
DNA is a negatively charged component so the amino acids most probably to combine with the DNA are going to exhibit a positive charge at pH 7. Thus, the likely amino acids would be Arginine, Histidine, and Lysine.
There are three amino acids, which possess basic side chains at neutral pH. These are lysine, arginine, and histidine. Their side chains comprise nitrogen and bear a resemblance to ammonia that is a base. Their pKa values are high enough that they seem to combine with protons, thus, attaining a positive charge in the process.
