Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Helicase is more active in the S phase of the cycle. Option A is the correct answer.
What are the events of the cell cycle?
The cell cycle consists of the interphase and the cell division phase, where the cell division takes a little time in comparison to the interphase. The parent cell spends the majority of its time in the cell cycle's interphase and less time in the cell division phase.
There are three phases in the cell cycle's interphase: G1, S, and G2. The cell grows in both the G1 and G2 phases, while the DNA replicates in the S phase.
Hence, helicase is an enzyme that is responsible for unraveling the double helix of DNA by breaking apart the hydrogen bonds between each base pair. Helicase is more active in the S phase of the cell cycle. Option A is the correct answer.

4. The stars at the edges of a galaxy are rotating around the galaxy’s center at the same speed as the stars in the middle of the galaxy. How does this provide evidence of dark matter?
Dark matter absorbs light from outside the galaxy, allowing the light of the stars in the galaxy to show the orbital speeds of the stars.
Dark matter emits the light that astronomers need to see the orbital speeds of the stars.
Dark matter subtracts gravity, which allows the stars to rotate at the same speed.
Dark matter provides the gravity that allows the stars to rotate at the same speed.
Answer:
Dark matter provides the gravity that allows the stars to rotate at the same speed.

Which of the following might make this ecosystem more sustainable?
A. if it supported more plant species, but fewer animal species
Answer:
Something that may make this sustainable is to remove food from there, or to add more animal species, particulary slightly invasive species that can eat the plants, and fast.
Oops didn't understand at first, yes this will make it more sustainable
Explanation:
To solve this we must be knowing each and every concept related to ecosystem. Therefore, an environment with a large variety of plant and animal species is the correct option.
What is ecosystem?An ecosystem is generated through the interaction of all life forms with each other as well as with the chemical and physical features of their surroundings, all of which are linked by the energy flow. It includes all of the living organisms in a given region in addition to their non - living things surroundings such as air, water, and sunshine.
Humans depend on ecosystems to meet their fundamental requirements. Ecosystems sustain us by providing safe drinking water as well as nutritious food. They supply raw materials for our clothes, housing, transportation, and energy needs. An environment with a large variety of plant and animal species is more sustainable ecosystem.
Therefore, an environment with a large variety of plant and animal species is the correct option.

Mecayla harvests oysters from the shallow waters of the marsh near her home. She eats the shellfish almost every day. Her brother Kendis dislikes oysters but eats local predator fish from the river three times a week. Recent water quality tests show moderate levels of heavy metals in the river and marsh. What is the most likely result of this pollutant on Mecayla and Kendis if they maintain the same diet?
Mecayla will get sick first because she eats oysters every day.
Kendis will get sick first because of less bioaccumulation.
Biomagnification will cause Kendis to become ill first.
Bioaccumulation will cause Mecayla to become ill first.
Answer: Biomagnification will cause Kendis to become ill first.
Explanation: This answer is correct because Kendis is eating the predator fish and Mecayla is only eating some oysters from the shallow water. Biomagnification causes the concentration of toxins, specifically in the predator fish, therefore Kendis will become ill first.
Mecayla harvests oysters from the shallow waters of the marsh near her home. Biomagnification will cause Kendis to become ill first.
What is the ocean?The existence of life on our planet is due to the oceans. Today, more than 230,000 marine species call the sea their home. Life began in the water.
Climate and temperature on Earth are governed by the oceans. They regulate temperatures and play a critical role in precipitation formation. The world's five oceans have a salinity that is around 3.5 percent on average.
The Mediterranean, the Atlantic, and the Bay of Bengal, on the other hand, have higher saline levels.
Therefore, Mecayla harvests oysters from the shallow waters of the marsh near her home. Biomagnification will cause Kendis to become ill first.

12.What is an invasive species?
A native species which are added to an area
A keystone species in an environment
A non-native species added to an area
Answer:
An invasive species is an introduced organism that becomes overpopulated and negatively alters its new environment. Although their spread can have beneficial aspects, invasive species adversely affect the invaded habitats and bioregions, causing ecological, environmental, and/or economic damage.
To be invasive, a species must adapt to the new area easily. It must reproduce quickly. It must harm property, the economy, or the native plants and animals of the region. Many invasive species are introduced into a new region accidentally
A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. ... Any organism, from plants to fungi, may be a keystone species; they are not always the largest or most abundant species in an ecosystem
An invasive species is an organism that is not indigenous, or native, to a particular area. Invasive species can cause great economic and environmental harm to the new area.
