Which image models the action of the enzyme helicase in the DNA replication process? A. a sewing machine B. a zipper C. a glue stick D. a copy machine
Answer:
the answer is a zipper
The replication of DNA is a zipper process. An enzyme called helicase is utilized to divide the two DNA strands that are present before DNA replication begins. Thus, option B is correct.
What is the zipper action of the enzyme helicase?Single-stranded DNA is created as a result of this energy-intensive unwinding reaction, which is needed as a template or reaction intermediate in DNA replication, repair, and recombination.
It splits the two DNA strands by unwinding the double helix. Helicase prepares the DNA strands for replication by separating and untwisting them.
It splits the two DNA strands by unwinding the double helix. Helicase prepares the DNA strands for replication by separating and untwisting them.
Therefore, DNA helicases accelerate the breaking of the hydrogen bonds that bind the double-stranded DNA's two strands together.

source of energy (2)
materials used by each process (2)
location of each process in the cell (2)
when each process occurs in plants and animals (2)
Answer:
Explanation:
Photosynthesis Vs. Respiration
1) Photosynthesis gets it's energy from sunlight, and uses the sunlight to change water and CO2 into energy. Cellular respiration gets it's energy from glucose molecules and oxygen.
2) Photosynthesis uses energy, CO2, and water to make energy and releases oxygen. Cellular respiration uses glucose molecules and oxygen to make energy, and releases CO2 and water.
3) Cellular respiration takes place in the mitochondria, and photosynthesis takes place in chloroplasts.
The energy from photosynthesis is gotten from sunlight and uses the sunlight to change water and carbon dioxide into energy.
Photosynthesis refers to the process through which green plants transfer light to chemical energy. Respiration refers to the biochemical process where the cells of an organism get energy through the combination of glucose and oxygen.
Photosynthesis uses energy, carbon dioxide, and water to make energy and release oxygen. Cellular respiration gets its energy from glucose molecules and oxygen. Cellular respiration uses glucose molecules and oxygen to make energy and releases water and carbon dioxide. Lastly, cellular respiration takes place in the mitochondria while photosynthesis takes place in the chloroplasts.

Suggest ONE reason why some plants have no dispersing seeds
Answer:
Some plants don't use seeds to grow.
Explanation:
For example bananas grown from bulb or rhizome. They are the result of a genetic selection.
Answer:
Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds.

hopefully this helps you
An autotroph is a type of organism who can produce its own food. Therefore, Producer is the best option.
What is autotroph?An autotroph is a type of organism that can produce its own food using inorganic substances or obtaining energy from the sun. Producers, such as plants or algae are able to prepare their own food by performing photosynthesis where they can convert sunlight into energy, thereby, playing a very important role in the food chain.
Plants perform photosynthesis which involves the use of sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar, such as glucose, thereby preparing their own food, but also serves as a source of food for other living organisms as well.
However, consumers, such as herbivores and carnivores are dependent on other organisms to obtain energy, while decomposers feed on dead organisms to obtain energy and return nutrients to the soil.
Therefore, producers are the organisms that prepare their own food, and hence called autotroph.

hurricanes come from
Answer:
Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the large storms that form over the Atlantic Ocean or eastern Pacific Ocean. ... As the wind passes over the ocean's surface, water evaporates (turns into water vapor) and rises.
Answer:
Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form.

The nervous system interacts with the endocrine system by.
A. sending neurotransmitters to endocrine target cells
B. sending neurotransmitters to neuroendocrine cells
C. receiving messages from hormones
D. translating messages from endocrine cells.
Answer:
c. receiving messages from hormones.
Explanation:
a primary function of the sympathetic and parasympathetic nervous systems is to interact with the endocrine system to elicit chemicals that provide another system for influencing our feelings and behaviours.
A gland in the endocrine system is made up of groups of cells that function to secrete hormones. A hormone is a chemical that moves throughout the body to help regulate emotions and behaviours. When the hormones released by one gland arrive at receptor tissues or other glands, these receiving receptors may trigger the release of other hormones, resulting in a series of complex chemical chain reactions. The endocrine system works together with the nervous system to influence many aspects of human behaviour, including growth, reproduction, and metabolism. And the endocrine system plays a vital role in emotions. Because the glands in men and women differ, hormones also help explain some of the observed behavioural differences between men and women.
Which of these is an organ of the endocrine system?
