Answer:
I think due to absence of ATP but I'm not sure.. Actin and myosin return to their unbound state causing the muscle to relax. Alternatively relaxation (failure) will also occur when ATP is no longer available.
Myosin heads are ready to bind with the actin filament they are not able to bind due to the absence of ATP.
How two myofilaments involved in muscle contraction?Muscle contraction results from an intercommunication between the actin and myosin filaments which generate movement relative to one another.
What happens to the actin and myosin filaments when a muscle contracts?Myosin movement appear to be a kind of molecular hop. The myosin reaches forward, binds to actin, contracts, releases actin, and then reaches forward again to bind actin in a new cycle.
What happens to actin and myosin during muscle relaxation?Relaxation occurs when nerve stimulation stops. Calcium gets moved back into the sarcoplasmic reticulum shattering the link between actin and myosin. Actin and myosin then return to their unbound state causing the muscle to relax.

You are concerned with surveying the protozoa in the arboretum soil. While most commonly thought to live exclusively in aquatic environments, protozoa can play an important role in the nutrient cycling that takes place in soil. In addition, protozoa can help maintain the proper balance of bacterial populations within soil, as bacteria are a primary source of food for protozoa. Protozoa are extremely diverse. However, there are three characteristics common to all organisms called protozoa. What are these three characteristics
Answer:
eukaryotic, unicellular, without a cell wall
Explanation:
Protozoans are single-celled eukaryotes that generally move through cilia, flagella, or amoeboid motion. After their discovery, protozoans were considered as single-cell animals due to their animal behavior (including predation and motility), and because they don't have a cell wall, as observed in algae and plants. Some examples of protozoans include Paramecium, Amoeba, and Trypanosoma. Nowadays, the term 'protozoans' is still used to describe unicellular eukaryotic organisms from the Protista kingdom that are heterotrophs, i.e., unicellular microorganisms that acquire energy and nutrients from other organic sources, especially plant and animal matter.

Which consequence is a direct result of human population growth
Answer:
One of the largest environmental effects of human population growth is the problem of Global warming.
Economic development, urbanization, energy consumption, transportation/motorization due to rapid population growth are major driving forces of air pollution in large cities.
In order to support the growing population, forests are being destroyed at an alarming rate. Deforestation occurs when humans clear forests to use the land either for agriculture or for habitation. This leads to soil erosion and the extinction of plant species. Land animals also decline in numbers and even face extinction due to human expansion that encroaches on their natural habitat and limits their ability to spread geographically.
Humans also continue to put a great demand on the natural resources of our planet. Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy. Many parts of the world also suffer from a shortage of food and water.
The growth of the population puts larger demands on our already limited resources. The environment on earth is suffering from the growth of the global population. The depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious problems.

sorry it is so long but here u go plz leave a like and a rating and brainliest
The direct result of human population growth include consequences such
as pollution.
Increase in human population has led to an increase in industries and
use of automobiles which emits different gases which are harmful. They

Preparing Informative Presentations
There are a variety of reasons a person presents a speech. Perhaps the most common reason is to present timely or useful information to an audience.
Such speeches are called expository speeches, and they rely on the effective transfer of information to listeners. An expository speech could be a definition speech, which explains an object, person, or event. It could also be a demonstration speech, which explains to the audience how to complete a process or task. A successful informative presentation depends on a few key steps that will help you prepare, inform, engage, and educate.
Based on the tips in the article, come up with a topic of your own that would make an interesting demonstration speech?

Jaguars are a keystone species in the Amazon. Describe how they can be so essential to the ecosystem despite
being significantly less abundant than many other species.
Answer:
jaguars are keystone species because they feed herbivorous species that might decimate the plants of the ecosystem
Explanation:
Keynote species are species that help to maintain the homeostasis of the ecosystem so if they lack then the ecosystem would change drastically. Moreover, a top predator is a predator that occupies the highest trophic level in the food chain. Jaguars are both keystone species and top predators that feed herbivorous species, maintaining the health of the food chain by eliminating the excess of primary consumers that otherwise would feed too many plants (i.e., primary producers) which produce and store energy at the bottom of the food chain.

Recall in class the example of incorporating heavy or light nitrogen labels into DNA to investigate how DNA is replicated. Imagine if, instead of labeling DNA, the experiment used heavy labeled RNA bases. What would be the outcome if you examined the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases?
Answer: You would not notice any difference or any labeled base, because RNA is not used to make DNA.
Explanation:
DNA is a molecule that contains the genetic information in all living things. The molecule consists of two strands that wind around each other to form a double helix structure where the strands are joined by hydrogen bonds. It is a nucleotide polymer where each nucleotide consists of a sugar called deoxyribose, a nitrogenous base (which can be adenine, thymine, cytosine or guanine) and a phosphate group (derived from phosphoric acid). What distinguishes one polynucleotide from another, is the nitrogenous base and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information.
Consider that DNA replication is semi-conservative, which means that each strand of the DNA double helix functions as a template for the synthesis of a new complementary strand. This process leads from one starting molecule to two "daughter" molecules, in which each new double helix contains one new and one old strand. Then, if nitrogen tags are incorporated into the DNA, they will register on the old strand of the new DNA molecule.
On the other hand, RNA (ribonucleic acid) is a molecule similar to DNA but has only one strand and consists of a sugar (ribose) and alternating phosphate groups. Attached to each sugar is one of the four bases adenine, uracil, cytosine or guanine. The process of RNA synthesis, called transcription, consists of making a complementary copy of a piece of DNA. During this process, an enzyme called ARN polymerase, adds nucleotides that are complementary to the DNA strand. Then, this new RNA strand has new nucleotides. Thereby, if you examine the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases, you would not notice any difference or any labeled base, because RNA is not used to make DNA.
