1. What
events take place during the cell cycle?
2. How does the structure of DNA
help account for the way in which DNA copies itself?
Answers
Answer:
What happens during each stage of the cell cycle?
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

How are genetic code and gene expression similar?
Answers
Answer: Gene expression is the process the cell uses to produce the molecule it needs by reading the genetic code written in the DNA. To do this, the cell interprets the genetic code, and for each group of three letters it adds one of the 20 different amino acids that are the basic units needed to build proteins.

Non-protein-coding genes (genes that specify functional RNAs) are still transcribed to produce an RNA, but this RNA is not translated into a polypeptide. For either type of gene, the process of going from DNA to a functional product is known as gene expression

You place two fish in different sized tanks, after a month, you measure the length of the fish.
What is the manipulated variable and the responding variable?
Answers
Answer:
The manipulated variable is how many fish you put in the tank. The responding variable is how much the fish have grown.
Explanation:
A manipulative variable is the independent variable in an experiment or equation. It's called “manipulated” because it's the one you can change in the problem. A responding variable is something that “responds” to changes you make in an experiment. Hope this helps!

c. water fleas, diving beetles
d. heron, perch
e. one thing that could happen if all frogs suddenly died is that there would be an overpopulation of slugs, insects, and beetles. another thing that could happen would be that foxes would only rely on getting slugs for food so the slugs would soon go extinct and the plants would possibly over populate.

a. Producer: Land plants and tiny water plants.
a. Three consumers: Slug, insect, and newt.
b. Food chain with six levels: Land plants, insects, diving beetle, small, perch, and heron.
c. Small fish eat diving beetle and water fleas.
d. Heron and perch each small fish.
e. Food will decrease for foxes and herons in the food web.
a. Within the given food web, land plants and tiny water plants serve as the primary producers. They capture energy from the sun and convert it into usable energy through photosynthesis.
b. Moving along the food chain, the insects, such as caterpillars or grasshoppers, serve as a food source for other organisms.
c. The land plants provide energy to the insects, which in turn provide energy to the diving beetle. The diving beetle sustains the small perch, which is then consumed by the heron.
d. Heron and perch each small fish in the given food web. Perch and Heron are consumers of small fishes.
e. In the given food web, if there were a decrease in the population of small fish such as perch and water fleas, which are part of the diet of herons and small fish respectively, the herons and foxes would experience a decrease in their food supply. This would likely have an impact on the population dynamics and interactions within the food web, potentially leading to changes in the abundance and distribution of the organisms involved.

An Exoskeleton be a disadvantage for growth and movement because exoskeleton Restricts the growth of the organism due to its rigidity.
what is an Exoskeleton?In contrast to the interior skeleton of a human, an exoskeleton is the external skeleton that supports and protects an animal's body. Some of the larger exoskeletons are referred to as "shells" in common language.
what are the advantages of Exoskeleton?Having a hard covering on the outside in the form of an exoskeleton is a great defense against predatorsit helps to support the body and it's like wearing a portable raincoat that keeps the creature from getting wet or drying outIt also protects the fragile interior organs and muscles of the animal from harmwhat are the disadvantages of Exoskeleton?An exoskeleton provides a significant restriction on growth. Arthropods must exfoliate, shedding their old shell and growing a new one, because their exoskeletons do not grow with them

Answers
Answer: Glucose and Oxygen
Explanation: The two products of the light dependent reactions in photosynthesis are glucose and oxygen and are produced through the reconstruction of water and CO2 in the air. The light independent reactions also known as cellular respiration is a process identical to the human cellular respiration where glucose is broken down and rearranged with oxygen to create mechanical energy leaving CO2 and H2O left over.
