The exoskeleton of an insect provides a stiff, protective armor. Despite the protection, How might an exoskeleton be a disadvantage for growth and movement?
Answer:
They can’t expand or stretch with out a synthesize a new exoskeleton underneath the old one and then sheds or molt the original covering.
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
thus exoskeleton may provide protection to the insect but ristricts the growth of arthropod.

explain how transport across the plasma membrane is related to the homeostasis of the cell.
Transport across the plasma membrane is fundamental for maintaining an equilibrium state in the cell.
The cells need to carry out different metabolic processes such as reproduction, growth, differentiation, etc.Many of these processes require the presence of certain substances as well as concentration gradients to be performed.Moreover, the cells also need to eliminate waste products that otherwise would be toxic for them.In conclusion, transport across the plasma membrane is fundamental for maintaining an equilibrium state in the cell.

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.

Answer:
The outgroups can usually be identified by locating the terminal taxa that branch off nearest the base of a phylogenetic tree. On this tree, the outgroup is the fairy shrimp � a group of crustaceans that are closely related to the insects.
Explanation:
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?
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!

which type of medium supports the growth of the widest range of bacteria
The medium that supports the growth of the widest range of bacteria is the enriched medium.
Agar plate mediums are used to promote the growth of certain bacterias needed for studies. Some bacteria respond well to one medium, but will not grow in another. For this reason, many kinds of mediums exist, including:
MinimalEnriched Selectivedifferentialand many others.
The Enriched medium supports the growth of the widest range of bacteria by containing a wide variety or nutrients and lacking in inhibitors like that of the enrichment medium which would not allow certain bacteria to grow.

The reactants for a biochemical reaction are C6H12O6 + 6O2. What will be the products for this reaction, and where does the reaction take place?
Answer:
Glucose ( 6 carbon atoms) is split into 2 molecules of pyruvic acid (3 carbons each). This produces 2 ATP and 2 NADH. Glycolysis takes place in the cytoplasm. This breaks down the pyruvic acid to carbon dioxide.\
It takes place both in plants and animals.

Researchers have identified and sequenced the genes encoding proteins associated with nuclear pores in both yeast and vertebrates. They have used these data to determine the amino acid sequences of these proteins and have applied molecular modeling techniques to predict the three-dimensional structures of the proteins. All contain nearly identical folding regions that may serve to hold lipid membranes in sharp curves. Because this finding has been demonstrated in both yeast and vertebrates (representing organisms that diverged long ago in evolutionary history), it provides evidence of a possible mechanism for the evolution of a subcellular structure. Which subcellular structure is this

What are the products of the light reactions used for during in the dark reactions of photosynthesis?
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.
