What was the result of using drainage blocks to keep water in the field level during the growing season?
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).

What were the ancestors of mitochondria according to the endosymbiotic theory?
20 points
A. Aerobic eukaryotes
B. Aerobic bacteria
C. Anaerobic bacteria
D. Chloroplasts
Answer:
d is your answer
Explanation:
Ancestors of Mitochondria were aerobic bacteria, according to endosymbiotic theory.
What is endosymbiotic theory ?According to Lynn Margulis' endosymbiotic theory, mitochondria in eukaryotes are thought to have originated via an endosymbiotic connection with purple photosynthetic bacteria around 1.5 109 years ago. The endosymbiont, which had been captured, was subsequently transformed into a useful organelle bound by two membranes. Supporting data for the endosymbiont theory.
Prokaryotic cells and mitochondria are the same size. The DNA found in mitochondria is structurally identical to bacterial DNA. Similar to bacteria, mitochondria are self-replicating cells divide by binary fission Two membranes enclose mitochondria, and the inner membrane is structurally very similar to that of bacteria.
Therefore, aerobic bacteria are the ancestors of mitochondria.

Explanation:
What happens to the actin and myosin during a muscle contraction?
Answer:
Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.

High tide is occurring on the sides of the Earth that are_______.
A. -experiencing sunrise and sunset.
B. -closest to and farthest from the Sun.
C. -halfway between the Sun and the Moon.
D. -closest to and farthest from the Moon.
High tide is occurring on the sides of the Earth that are closest to and farthest from the Moon. The correct option is D.
What is high tide?When the sea or a river reaches its greatest level and moves the farthest up the beach or the bank, it is said to be at high tide.
The gravitational forces that try to pull the water away from the moon are resisted by the water that is travelling away from the moon.
On the far side of the Earth, where the moon's gravitational pull is weaker, inertia triumphs, the ocean swells, and high tide happens.
The rise and fall of the sea's surface on a regular basis is what tides, which start in the oceans, appear as as they move toward the coastlines.
High tide is when the wave's highest portion, or crest, reaches a specific area; low tide is when the wave's lowest portion, or trough, happens.
Thus, the correct option is D.
