Create a food chain. Choose the biotic factors from the list and move them onto the hotspots marked with circles. BIOTIC FACTORS Trout Algae Herons Minnows Mosquito larvae Regenerate Reset Check

Answers

Explanation:

algae(producer)>mosquito lavae>minnows >trout >herons

Algae, Mosquito larvae, Minnows, Trout, and Herons are arranged in the following pattern in a food chain.

What is a food chain?

A food chain is an arrangement of organisms where energy flows from through lower organism to higher organism. Each organism in the chain transfers energy to the other organism present at higher order and the flow of energy goes on. Biotic factors, algae, mosquito larvae, minnows, trout, and herons are arranged in the following sequence in the food chain.

Algae are the primary producers in aquatic ecosystems which are eaten by mosquito larvae, which are then eaten by minnows. Minnows are then eaten by trouts. Herons, being the largest predator feeds on the trout.

Each organism in the food chain obtains energy from the organisms present at lower trophic level. However, the energy flow decreases at each trophic level, therefore, the organism at higher trophic level receives the less amount of energy.

Therefore, the food chain is created in the following order: Algae, Mosquito larvae, Minnows, Trout, and Herons.

During which eon did Pangaea come together?

Archean

Hadean

Phanerozoic

Proterozoic

Answers

Phanerozoic is the answer

Pangaea came together during the Phanerozoic eon.

• The current geologic eon in the geologic time scale is the Phanerozoic eon. It is the one during which abundant plant and animal life prevailed.

• It is of the span of 541 million years to the present, and it started with the Cambrian period when animals initially developed hard shells.

• The Phanerozoic time span began with the sudden emergence of fossilized evidence of a number of animal phyla, the development and emergence of complex plants, and the evolution of fish, the emergence of tetrapods and insects, and the development of present time fauna.

• During the Phanerozoic eon, the tectonic forces moved the continents and gathered them into a single landmass called Pangaea, which later got separated into the present continental landmasses.

Thus, the correct answer is Phanerozoic eon.

DNA is in what form during interphase?

Answers

Answer:

During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).

DNA is in form during interphase During interphase, the cell DNA isn't condensed and is loosely distributed.

What happens during interphase?

A stain for heterochromatin (which shows the placement of chromosomes) indicates this large distribution of chromatin. The equal stain additionally indicates the organized, aligned shape of the chromosomes in the course of mitosis.

Nuclear DNA remains in a semi-condensed chromatin structure throughout the interphase. During the S phase, DNA replication results in the creation of identical pairs of DNA molecules, known as sister chromatids, which are tightly linked to the centromeric region.

During the S phase, the centrosome is duplicated.

Which process best explains how antibiotic resistance in bacteria can occur?

Answers

Answer:

Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

A cup is surrounded by air in room temperature
Describe the energy transfer between the water and air if the system is at equilibrium

A.Energy is transfers from air to the water

B. Energy transfers from water to the air

C. Energy transfers back and forth between air and water

D.None of the above

Answers

I think the answer is D. I’m bot sure though I learned about this last year so my memory on it isn’t the best

The energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy. So, the correct option is D.

What do you mean by Equilibrium state?

Equilibrium may be defined as a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.

When the system is at equilibrium, the energy transfer between water and air surrounding the cup does not take place. It will only take place when there is a difference between the concentration of two solutions or objects.

Therefore, the energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy.

The evolution of arthropods has led to

Answers

Answer:

Arthropods make up almost 80% of all animals; they are jointed legged animals that belong to the Animalia kingdom that include centipedes, millipedes, insects, and spiders. The success of arthropods can mainly be attributed by the following characteristics;

Presence of Exoskeleton.

The presence of exoskeleton that hardens due to the presence of chitin offers a protective cover for arthropods with different environment against advance conditions and also it protects against dehydration.

Varied habitats.

Arthropods can be found in all types of habitats from the soil, water, and land. This feature is the key to their survival since they are widely distributed hence increasing chances of survival.

Bilateral Symmetry.

Arthropods exhibit bilateral symmetry whereby a different portion of their bodies are mirror images, this form is exhibited in higher animals such as humans and dogs, and it facilitates advanced body functioning.

Jointed Legs.

Arthropods exhibit segmented legs that are jointed to allow the development of hard exoskeleton for protection. The jointed legs are specialized for grasping, jumping and running.

Short generation time.

Arthropods exhibit short generation time, which allows for faster adaptation to the environment and survival.

Reproduction strategy.

Arthropods have exhibited a sexual form of reproduction that is more successful in the growth and survival of offspring.

Segmented body.

Arthropods have a segmented body that allows for specialization of body organs and tissues, and this has promoted their success by specializing body organs to different functions.

Describe the advantage of broad-leaved trees losing their leaves as winter sets in and the advantage of needle-leaved trees keeping their leaves if they are in poor soil

Answers

Answer:

The advantage of shedding broad leaves in the winter is to conserve the energy that needs to expand in order to provide heat to each part of the plant including leaves as in winters it becomes very dry and cold. If they do not shed their leaves they have to spend more energy to spend energy on leaves.

Needles like leaves have a thick cuticle layer that prevents from losing water in dry conditions or conditions with a limited amount of water in the soil. These leaves also help in photosynthesis by capturing more sunlight as they have a larger surface area. These adaptions can live in poor soil, rain and snowy conditions.
