Answer:
Your answer is chlorine.
Explanation:
Valence electrons help in predicting chemical reactions. For example, since hydrogen (H) is in group 1, it has 1 electron in its outer energy level. Chlorine (Cl), which is in group 17, has 7 electrons in its outer energy level and is one electron short of having a "full" outermost energy level.

Wildlife can be scarce in many large, densely populated cities. A few plants and animals can be found in theseareas. For example, rats, mice, pigeons, cockroaches, and other insects are common in cities. Trees can grow by sidewalks or in local parks. Some cities even have small populations of coyotes within city limits.
Do you think these cities meet the definition of an ecosystem? Explain your reasoning.
Answer:
Yes
Explanation:
Considering that other lifeforms, more than one species, is able to live in those cities, mean that its abiotic factors can sustain life. An ecosystem is a community with biotic (living organisms) and abiotic factors (environment).

Composed primarily of pyramidal-shaped zymogenic cells that produce enzymes. What is the primary enzyme produced here, and what substance does it break down
The pyramidal-shaped zymogenic chief cells produce pepsinogens which act on proteins molecules.
What are chief cells?Chief cells are cells are located at the base of the gastric glands found also in the body and fundus of the stomach.
Chief cells are pyramidal-shaped zymogenic cells that produce enzymes such as pesinogen 1 and 11.
The pepsinogens are proenzymes or zymogens and are converted to the active enzymes person 1 and person 11.
Pepsin 1 and 11 are proteolytic enzymes and act on proteins to break them down.
Therefore, chief cells produce pepsinogens which act on proteins molecules.

Which statement is true about cellular respiration?
a. It produces glucose, which provides energy for the cell.
b. It produces carbon dioxide, which combines with hydrogen to form sugar
c. It produces ATP, which stores energy that is used by the cell.
d. It produces oxygen, which combines with hydrogen to prevent cell poisoning.
Answer:
I think b.
Explanation:
Cellular respiration uses glucose and oxygen to form co2.
It produces glucose, which provides energy for the cell.
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.What is cellular respiration?It is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.There are four stages:- glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation.To know more about cellular respiration here

Biomass and fossil fuels similarities
Answer: Biomass and Fossil fuels are similar to coal with an oxygen atom added.
Natural gas is the best fossil fuel in terms of energy output per unit carbon dioxide emitted. While Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel.
Explanation: Fossil fuels and biofuels are similar in that they are both formed from once living matter and both emit carbon dioxide when burned for energy.

how do muscle cells produce energy through aerobic and anaerobic respiration
Answer:
Cellular respiration is the process by which cells make ATP by breaking down organic compounds from food. Muscle cells are able to produce ATP with oxygen, which is called aerobic respiration, or without oxygen, an anaerobic process called anaerobic glycolysis or fermentation.

A six-year-old Caucasian boy was seen by a maxillofacial surgeon to be evaluated for surgical repair of severe jaw misalignment. The boy was deemed an appropriate candidate for surgery at this time, with a second surgery planned during his teen years to complete the correction. The boy was adopted, and no family history was available. He had no personal history of excessive bleeding or bruising. The pre-surgical CBC results including platelet count were within reference ranges. Pre-surgical hemostasis testing is as follows: Ryan L. Reference RangePT 10.5 9-12 secondsAPTT 40 32-46 secondsBleeding time 7 1-9 minutesRequired:Describe the principle and reagents for the PT and APTT.
Answer: The PT and APTT are valuable blood clotting time determination principles.
Explanation:
The principle of PT or prothrombin test determines the time required for the clot formation when additional calcium factor is added.
The principle of APTT or activated partial thromboplastin time is a test which determines the time required for the formation of the blood clot after the adding the calcium and phospholipid factors. This process activates the different blood clotting factors in the blood responsible for clotting of blood.

3. Which of the following best describes a marsh?
deep ocean water miles from a river's mouth
a rocky, coastal area with very high tides
a shallow, sheltered area near an estuary
a sunny, open area with lots of sand dunes
I NEED HELPPPP HURRRYYYY
Answer: a rocky, coastal area with very high tidesa shallow, sheltered area near an estuary
Explanation: because it’s an area low-lying land which is flooded in wet seasons or at high tide, and typically remains waterlogged at all times.
Answer:
C) a shallow, sheltered area near an estuary
Explanation:
A marsh is a shallow, sheltered area generally found near an estuary. They are often between aquatic and terrestrial ecosystems. Like other marine ecosystems, some marshes experience tides. Therefore, these tidal marshes are exposed during low tide and underwater at high tide. Marshes that are not as close to the coast are called nontidal marshes.
----------------------------------------------------------------------------------------------------------
More information on marshes:
The producers that thrive in marshes are herbaceous, meaning they do not have woody stems. Just like estuaries, marshes are rich in nutrients and are home to an abundance of wildlife.
Neurons have special proteins in their
cell membranes that allow them to generate
electrical current. Are these proteins most
likely produced by ribosomes on the rough ER
or ribosomes suspended in the cytoplasm?
Explain your answer.
Answer:
The ribosomes on the rough endoplasmic reticulum (RER) most likely produces neuronal special proteins.
Explanation:
Conduction of electrical impulses by action potentials of neurons takes place through controlled flow of charged ions through neuronal membranes. This ion transfer is controlled by specialized neuronal channel proteins which are present in the neuronal cell membrane.
These channel proteins allow for hydrophillic passage of ions and water molecules across the neuronal membranes.
Ribosomes that are attached to the RER are involved in protein synthesis. They carry the code for proteins carried by the mRNA and translate into respective protein.
The RER along with some free ribosomes cluster together as Nissl bodies and are mainly involved in neuronal specialized proteins.
