Answer:
ACDFHope it helps youThe systems affected by cystic fibrosis are the respiratory, gastrointestinal, reproductive, and integumentary.
Cystic fibrosis is a condition that damages organs in the gastrointestinal system or digestive system and the respiratory system. It can lead to damages in:
The lungs (respiratory system)The pancreas (gastrointestinal system)This condition is caused by the accumulation of mucus on organs due to a defective gene. This accumulation leads to negative effects in these systems but also in other systems such as:
Frequent respiratory infection (respiratory system)Damage to the airways (respiratory system)Digestive problems such as diarrhea or constipation (digestive system)Infertility (Reproductive system)Yellowing of the skin (integumentary system)Thus, the systems affected are the respiratory, gastrointestinal, reproductive, and integumentary; while others such as the lymphatic or neurological are not affected.

Use complete sentences or list form in order to describe the steps of replication. You must
use the following words and underline them:
Nucleus Helicase
Complementary strand
DNA Polymerase Ligase
Okasaki Fragments 5’ to 3’ Leading strand
Lagging strand
Answer:
Please find the description of the steps involved in DNA replication below. The terms listed in the question are written in BOLD.
Explanation:
DNA replication is the process by which DNA molecule is duplicated in the genome to produce two identical copies. DNA replication, which must occur prior to any cell division, involves the following steps:
- An enzyme called DNA HELICASE unwinds the double strand of DNA into a Y-shaped replication fork.
- Another enzyme called DNA POLYMERASE attaches to the single strand of DNA to add nucleotides to the growing DNA molecule.
- An enzyme called DNA PRIMASE adds a short nucleotide sequence called PRIMER, which serves as foundation for DNA polymerase to act upon.
- The DNA polymerase adds nucleotides based on complementary base pairing rule i.e. A-T, G-C.
Nucleus Helicase
Complementary strand
DNA Polymerase Ligase
Okasaki Fragments 5’ to 3’ Leading strand

Describe: Fossil fuels are used in many ways. Using the Gizmo, describe the main use for each fuel.
Coal:
Petroleum:
Natural gas:
In each case, what is the end product of burning the fossil fuel, and where does it go?
Answer:
Coal:
Coal is primarily used as fuel to generate electric power
Petroleum:
heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials
Natural gas:
heating, cooking, and electricity generation.
it all end up in the atmosphere
Explanation:
The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.
petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.
Like oil, natural gas is a product of decomposed organic matter, typically from ancient marine microorganisms, deposited over the past 550 million years. This organic material mixed with mud, silt, and sand on the sea floor, gradually becoming buried over time.
Coal and natural gas are burned in power plants to boil water. Steam from boiling water converts turbines into electricity. Carbon dioxide from burning fuel is released into the atmosphere.
This is about description of fossil fuels which are simply fuels that are formed from natural processes.
The uses and end products of fossil fuels are talked about in the explanations below;
1) (I) The primary use of the fossil fuel named coal is to generate electricity.ii) When coal is burnt, it produces a very high heat. This heat is so high that it converts water into high-pressure steam. What drives a turbine is a high pressure steam and this drive makes the turbine to produce electricity.
2) I) Petroleum products are used to set vehicles in motion, for asphalt on roads, production of electricity and heating of buildings.II) when petroleum is burnt to create energy, it produces high amount of carbon dioxide and other toxic gases into the atmosphere that can cause greenhouse effect.
3) I) Natural gas is used primarily as a source of energy for cooking, generating heat and for providing electricity.II) When it undergoes combustion is produces large amount of carbon dioxide and nitrogen oxides into the atmosphere.

A Mismatch occurs when:
A. organisms that were well adapted to one environment cannot evolve rapidly enough to adapt to new circumstances.
B. when an organism is well adapted to its environment
C. when an organism inherits a mutation that decreases its reproductive success
D. when a mutation increases the reproductive success of an organism
Answer:
A
Explanation:
A mismatch occurs when organisms that were well adapted to one environment cannot evolve rapidly enough to adapt to new changes in the environment. Hence, a trait that once confers an adaptive advantage becomes inimical due to the changes in the environment.
In order words, a mismatch occurs when a once adaptive trait becomes maladaptive or no longer confers an adaptive advantage to organisms due to a change in the environment but still persists in organisms.
For example, an organism with a body adapted to aquatic habitat suddenly finds itself in a terrestrial habitat due to climate change. The body that use to be adaptive to the environment would suddenly become maladaptive to the new environment.
The correct option is, therefore, A.
For the animal you choose, briefly describe it (physical description, habitat, etc.). Then, list all the organ systems of the animal. From this list, choose one organ system to describe in detail. Describe how the whole system works and functions. Include the function of every organ involved in that organ system.
Answer:
he Axolotl, or the Ambystoma mexicanum, is located in the class amphibia and in the family of Ambystomatidae. They are a critically endangered species that resides in Mexico. More specifically, the walking fish is native only to Lake Xochimilco and Lake Chalco in central Mexico. These unique fish have many attributes that makes it different from other amphibians and fish found in lakes.
Axolotls are 9 inch "walking fish" that have the amazing ability to regenerate limbs. They can regenerate any lost limb, including their head. This salamander has a soft bodies with small "horns" sprouting from the sides of their head. These horns are actually gills, meaning that instead of having their gills located inside of their pharynx the frills are set on the sides of their head.
The spots commonly found on an axolotl are not unusual, it's part of an extremely advanced system called the lateral line system. This system consists of electroreceptive ampullary organs and mechanoreceptive neuromasts organized into lines across the creature's body. This system is connected to the nervous system, and it allows the axolotl to sense movement and vibrations in the water.
