Enzymes (Catalysts) lower the required activation energy, allowing the reaction to happen more quickly.
Answer:
This question is asking to identify the directional relationship between the following organs. They are explained below.
Explanation:
1. The heart is MEDIAL to the lungs because it is located towards the middle in relation to the right and left lungs.
2. The knee is DISTAL to the hip because it is farther away from the point of attachment of the hip joint.
3. The wrist is PROXIMAL to the hand because the wrist is closest to the point of origin of the hand.
4. The mouth is INFERIOR to the nose because it is lower in direction to the nose.
5. The thorax is SUPERIOR to the abdomen because it is located above the abdomen.
6. The thumb is DISTAL to the ring finger because it is far away from the ring finger.
7. The sternum is ANTERIOR to the heart because it lies in front of the heart
8. The skull is SUPERFICIAL to the scalp because it is close to the body surface.
9. The ears are LATERAL to the nose because it is towards the middle line of the nose
10. Dorsal refers to the BACK of the human body, while ventral refers to the FRONT of the human body.
Answer:
B. Stress caused by forces that stretch an area of the crust made the rock to break
Explanation:
From the picture inserted to this problem, we see a unit that has been severely fractured.
Fracturing results from the brittle deformation of a rock under applied stress.
- Rock fracturing results in the formation of joints and faults.
- We can obviously see different sets of joint sets on the body of the rock in the picture attacked.
- Also, a prominent fault which resembles an extensional fault can also be seen.
- Therefore, the stress caused the stretch of the area which in turn makes the rock the rock to break.
Complete question:
Prophase of meiosis I has some important differences from prophase of mitosis. These differences include: ___________BLANK pair, and _________BLANK occurs.
A: chromatids; condensation
B.,chromosomes; separation
C. homologous chromosomes; crossing over
D. homologous chromatids; separation
Answer:
C. homologous chromosomes; crossing over
Explanation:
Prophase I of meiosis and prophase of mitosis are quite distinct with respect to the events occurring in the cells. Prophase-I of meiosis is a relatively long stage. The Zygotene stage of prophase-I includes the pairing of homologous chromosomes. This pairing is mediated by synaptonemal complex and the process is called synapsis. The paired chromosomes undergo the process of crossing over during the pachytene stage of prophase-I. In crossing over, the non-sister chromatids of the bivalents exchange some genetic material between them. The events of synapsis and crossing over do not occur during prophase of mitosis.
