Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

Part 2: Name a process that could release this compound into the air.
Part 3: Explain how the elements that form it are conserved during the carbon cycle. Use complete sentences to explain your answer.
Justify how this compound was created from a recycling of carbon in the carbon cycle. Use complete sentences to explain your answer.
Answer:
Part 1 is carbon.
Part 2 is organisms decay.
Part 3 So, at the time of chemical procedures in the carbon cycle, the atoms of carbon are never destructed, however, they get rearrange and modify into distinct molecules. The mentioned cycle is essential for maintaining life on Earth.

While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)
Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).

Explanation:
Given the choice of 4 bases and the number of bases needed to make up a codon, how many possible codons are there? 16 23 64 128
Answer:
64
Explanation:
A codon is a group of three nucleotide sequence in a mRNA that specifies a particular amino acid acid. There are only four nucleotides composed of the four nitrogenous bases viz: Adenine, Guanine, Cytosine and Thymine/Uracil.
A codon is composed of only three of these nucleotide bases at a time. Hence, considering the number of nucleotide bases that can make up one codon and the 4 nucleotide bases, there can only be 4^3 = 64 combinations of the four nucleotides. This means that there are 64 possible codons.
A slug, frog, heron, bird, and grass plant are all part of the same food chain.

This pyramid, "the castle," is just one part of a large archaeological site that was a major city almost fifteen hundred years ago. It is believed that two groups of people, the Mayans and the Toltecs, called this city their home. The city included a marketplace, a plaza, a church, and an observatory, as well as a ball court, a temple for sacrifices, and a sinkhole which provided water for the people. The pyramid has four sides, each with ninety-one stairs; the four sets of stairs combine with the platform at the top to equal 365 three hundred sixty-five stairs-one for each day of the year. In addition, at sunrise and sunset on the spring and autumn equinoxes, the sun casts the shadow of a serpent moving down the pyramid toward the sinkhole. The observatory, used to study the sun, moon, and stars, provides further evidence of the Mayans' and Toltecs' interest in astronomy. Today this former city is one of the most popular in this south of the border country, seeing almost three million visitors each year.

write a paragraph explaining the flow of energy through a food web.
write a paragraph explaining the flow of matter through a food web.
Answer:
#1 = The living organisms of an ecosystem are related through food chains, which gives rise to trophic levels in an ecosystem. There is a flow of energy from one trophic level to the other in a food chain. Producers bring energy from the sun into the community. Primary consumers eat the producers, which makes them herbivores in most communities. Secondary consumers eat the primary consumers, which makes them carnivores. Tertiary consumers eat the secondary consumers. A final link in the food chain are decomposers, which break down the organic matter of the tertiary consumers (or whichever consumer is at the top of the chain) and release nutrients into the soil. Thus, there is flow of energy from Sun ------> Producer ------> Herbivore -------> Carnivore ------> Decomposers.
#2 = The flow of matter is connecting to all of the subjects involved. Several animals benefit off of the plants, then their predators benefit off of them, and so on. If even one of the factors of this food web were to go extinct, the entire thing would be messed up.
