Answer:

Explanation:

Firstly; the missing figure is attached in the diagram below.

Ligand A and ligand B can cause identical cellular responses in a cell due to the fact that there are cross-linkages in the various enzymatic activities taking place in the receptor proteins located in the plasma membrane.

This implies that a particular compound in the cell signaling in eukayortes can be triggered by some mechanism. For example as we can see right in the diagram; The ligands can trigger the G-protein in the plasma membrane which result into increase in cAMP.

In addition to that; IP3/DAG pathway can signal and trigger the calcium influx moving into the cytoplasm from the endoplasmic reticulum

Which feature is

Yanka [14]

Answer:

C. Coupled reactions establish an electrochemical gradient across a membrane.

Explanation:

During cellular respiration in mitochondria, and during photosynthesis in chloroplasts, the electron transport chain requires a proton gradient to pump protons across the membrane by active transport.
Protons flow back across the membrane by facilitated diffusion through ATP synthase, which utilizes them to phosphorylate ADP to ATP.
This process of ATP synthesis by harnessing the elctrochemicaal gradient geenrated by the diffusion of protons across the biological membrane through ATP synthase is called chemiosmosis.

What is the volume of the can? Area of top=40cm2 height = 12cm

Ilia_Sergeevich [38]

The volume of a can can be determined by the equation

Volume = Area x Height

Volume = 40cm^2 x 12cm = 480cm^3

To my esteemed Biology colleagues: 10/15/19 I am National Park Ranger, Imani. I am writing you as my park is in desperate need o

Zanzabum

Answer:

See explanation below.

Explanation:

1. Explain the difference in the roles of producers, consumers, and decomposers in the Everglades.

In the Everglades, producers would be all species of organisms that are autotrophs such as different species of plants. Consumers are categorized into three: primary, secondary and terciary consumers. Primary consumers feed on plants (e.g. insects), secondary consumers eat the primary consumers (e.g. mice or rats), while tertiary consumers are higher predators that eat the secondary consumers (e.g. racoons). Finally, decomposers are bacteria, archaeans, fungi, or worms that live in soil which decompose organic matter.

2. Based on your knowledge of how to classify living organisms, in what domain and kingdom do the producers, consumers, and decomposers belong?

In Biology, the three domains are Archaea, Bacteria, and Eukarya; while there are six kingdoms: Archaebacteria, Eubacteria (true bacteria), Protista, Fungi, Plantae, and Animalia.

Producers, that is plants, belong to the Domain Eukarya and the Kingdom Plantae.
Primary, secondary, and tertiary consumers also belong to the Domain Eukarya and to the Kingdom Animalia as they are all animals and eukaryotes.
Decomposers are classified into the three domains: Archaea, Bacteria, and Eukarya. Bacteria belong to the domain Bacteria, archaeans belong to the domain Archaea, and worms and fungi belong to the domain Eukarya. On the other hand, decomposers are classified into Archaebacteria, Eubacteria, Protista (oomycetes), Fungi, and Animalia (worms).

3. How did energy travel in the Everglades BEFORE the alligators were removed?

Aquatic plants (producers) <-- bass <-- bluegill <-- gar <-- alligator

Aquatic plants (producers) <-- zooplankton <-- bass/bluegill <-- wood stork <-- alligator

Plants (producers) <-- cattle <-- alligator

Plants (producers) <-- insects <-- rats <-- racoons <-- alligator

4. How did removing the alligators from the food web change how energy flowed in the Everglades?

Once the alligators were removed from the food web, the populations that were once in decline began to recover because of the lack of predators. Consequently, the lack of alligators led to the uncontrollable growth of racoons, wood stork, and gar, which could also cause an alteration as they consume ecologically and economically important fish species such as the bass and bluegill.

5. How did the problem begin, and what action(s) should Ranger Imani take to solve this issue?

The problem began when the populations of alligator, an apex predator that sits at the top of the food chain, grew at an accelerated pace. This led to the uncontrolled predation of other organisms that are also fundamental to maintain an ecological balance. Therefore, Ranger Imani decided to humanely euthanize the alligators, which were preying upon them. This led to a huge increase in wood stork, gar, and racoon populations.

Alligators should not be completely removed because they help to maintain an ecological balance. Instead, Ranger Imani should work on controlling populations by implementing Wildlife Population Management strategies, such as sustainable fishing, to prevent a certain species population from reaching a high number of individuals in order to keep a healthy ecosystem where all populations are stable because removing all apex predators is not the appropriate strategy as it significantly alters the ecosystem.

Fossils are found in _______.

Sergio [31]

Answer:

Sedimentary rocks

Explanation: Where are fossils found? Fossils are found almost exclusively in sedimentary rocks—rocks that form when sand, silt, mud, and organic material settle out of water or air to form layers that are then compacted into rock. So the answer will be Sedimentary rocks.
