A network of tubules that synthesize and transport materials needed for cellular growth and other functions is Smooth Endoplasmic Reticulum

Endocytic reticulum (ER)

Large and active, the endoplasmic reticulum (ER) plays a variety of functions in the cell, including calcium storage, protein synthesis, and lipid metabolism. Different domains, which are composed of tubules, sheets, and the nuclear envelope, carry out the various ER activities.

Many concerns remain regarding how the ER alters form in response to cellular signals, cell type, cell cycle state, and during organism development.

A number of proteins that contribute to the overall architecture and dynamics of the ER have been discovered. In this section, we go through what is known about the ER's dynamics, what is yet unknown, and how coordinated responses add to the levels of control in this dynamic organelle.

Answer:  1. Bear --> 2. Increase in cortisol --> 3. Increased heart rate --> 4. Slowing of digestion --> 5. Sweating --> 6. Bear is removed --> Body returns to normal

Hope this is of use to you!

Due to increase in hormones, Bear --> 2. Increase in cortisol --> 3. Increased heart rate --> 4. Slowing of digestion --> 5. Sweating --> 6. Bear is removed --> Body returns to normal.

Hormones are are the body's chemical messengers, sending signals into the bloodstream and tissues. Hormones work slowly, over time, and affect many different processes, including growth and development, metabolism – how your body gets energy from the foods you eat- sexual function, reproduction, and mood.

Hormones affect everything from blood sugar to blood pressure, growth and fertility, sex drive, metabolism, and even sleep. Their influence goes as far as changing the way we think and act day to day.

It's true that hormone imbalances can be associated with many problems, such as period problems, unwanted hair growth, fertility struggles, weight gain, and even difficulty sleeping. You should absolutely talk to your doctor about these things.

The unusual about organisms in the domain Archaea is that they live in extreme environmental conditions.

What is archaea?

Single-celled creatures fall under the realm of archaea (Singular archaeon). These microbes are prokaryotes because they lack cell nuclei. Although originally given the name archaebacteria (in the Archaebacteria kingdom), archaea were initially categorized as bacteria.

Prokaryotic organisms called archaea have evolved to exist in the most hostile circumstances where no other living thing can. Extremophiles are a group of archaea that have evolved to harsh settings like geysers, extreme cold, alkaline, and acidic temperatures.

Eukaryotic cells store their DNA in the form of linear chromosomes. This creates problems for the replication of DNA at the ends of the chromosomes because of the fact that DNA polymerase can only synthesize DNA in a 5' to 3' orientation.

The family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the basic building blocks of DNA, includes DNA polymerase. These enzymes, which are required for DNA replication, typically function in groups to divide an initial DNA duplex into two identical copies.

DNA polymerases' major function is to efficiently and properly replicate the genome in order to maintain the genetic code and ensure that it is faithfully passed down through the generations. While other DNA polymerases are primarily involved in DNA repair and translesion DNA synthesis, the third polymerase, Pol III, is responsible for duplicating the chromosomal DNA.

There are five DNA polymerases found in eukaryotic cells: and. The polymerase enzyme, which is found in mitochondria, is in charge of replicating mitochondrial DNA. The remaining four enzymes are thought to be involved in nuclear DNA replication because they are found in the nucleus.

The human population has changed since it first appeared on earth as The b. population has generally increased, and at rates that have varied over time.

Humans, as well as other populations, have changed since their appearance on earth. Some populations became extinct as they were not able to cope with the environmental changes whereas other became more adaptable and increased in number over time.

The human population has also increased with the passage of time. However, the increase in the rate of the human population was not a stable one. At some times in the past, the population number declined due to environmental factors such as the eruption of a disease etc.

However, with the passage of time, humans have managed to adapt themselves to the changing environmental conditions and their population is increasing rapidly.

Although a part of your question is missing, you might be referring to this question:

The human population has changed in ways that are similar to other populations. How has the human population changed since it first appeared on earth?

a. The population has generally increased at a relatively constant rate

b. the population has generally increased, and at rates that have varied over time

Membrane pores within a lipid bilayer are known as transmembrane channels. Protein complexes that traverse the membrane or peptides can generate the channels.

At the point where cells and the outside world meet, transmembrane proteins mediate the transmission of signals between them. They also carry out numerous crucial cellular biological processes.

Membrane transport proteins fall into two categories: carriers and channels.

The lipid bilayer is traversed by both of them in continuous protein routes.

Therefore, transmembrane membrane protein assists molecules in crossing the plasma membrane.
