Define element and explain element

Answers

Answer 1

Explanation:

An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds.A compound consists of two or more types of elements held together by covalent or ionic bonds.

What is the first aid for choking?​

Answers

respiration is when you breath and cellular respiration involves taking the cells from when you breathe and turning it into chemical energy.

partial blockage can be cause by cancer within the bowel area or inflammation within the bowel area. obstruction blockage is caused by tissue compressed in the gut.

Can someone give me an explanation of what coevolution is?

Answers

Answer: In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution.

Explanation:

In a small population of alpine foxes, you observe increased ear length over a 10-year period. Can you conclude that increase in ear length is advantageous in this population

Answers

Answer:

No, I can't conclude that because there are several factors that influence the expression of a trait (for example, gene drift)

Explanation:

There are several factors that affect the genetic variation of a phenotypic trait in populations with small sizes. Genetic drift is an important evolutionary mechanism by which allele frequencies change in populations, and it is well known that the effects of genetic drift are most pronounced in small populations. Moreover, gene flow -or migration- is an evolutionary factor (stronger in small populations) that is also potentially capable of changing allele frequencies and thus contribute to the overall genetic variation of a phenotypic trait. Finally, environmental factors (for example, abiotic and biotic stresses) may also be associated with the variation of a quantitative trait such as, in this case, ear length.

During the Devonian period of Gondwanaland what were the two organisms that thrived?
A) algae and Trilobites
B) land invertebrates and dinosaurs
C) conifers and early mammals
D) angiosperms and humans
E) marine invertebrates and land plants
PLS HELP ASAP

Answers

Answer:

about the Trilobites is =Trilobites ( /ˈtraɪləˌbaɪt, ˈtrɪ-, -loʊ-/;[4][5] meaning "three lobes") are a group of extinct marine artiopodan arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 300 million years.[6] . and about the algae is =Algae (/ˈældʒi, ˈælɡi/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts.

Describe how ATP synthase produces ATP.

Answers

Answer:

so it spins the hydrogen molecules to make the ATP

Explanation:

it occurs in the inner membrane of the mitochondria. The electrons drop off the energy and the hydrogen atoms are moving through the Protein channels/pumps. after that the NADH turns into nad+ and the fadh2 turns into fad. these then go back to the citric acid cycle to get the electrons back. (known as electron carriers) the hydrogen molecules get pumped up to the inner membrane space which would be active transport since we are going from low to high concentrations. the hydrogen molecules go down the atp synthase which spins to make the atp. this would be passive transport since its moving from high to low concentrations.

How does cellular respiration happen?

Answer in a minumum of 5 complete sentences

Answers

Answer:

Definition : "Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products."

Simplified : Cellular respiration is used to take in food, then is used to create ATP. ATP is a chemical the cell uses for energy. This process is called aerobic respiration. The process uses oxygen, and has four stages known as  Link reaction, glycolysis, the Krebs cycle, and the electron transport chain.

Why are leaves necessary for a plant?​

Answers

Answer:

PLEASE MARK AS BRAINLIEST!!

Explanation:

Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen.

Leaves are the primary way plants interact with the atmosphere and take care of their basic needs. a plant can only survive for a few days without leaves. If the plants doesn't have any leaves than the plants wouldn't exist in the earth because leaves prepare food for the plants through the process of photosynthesis. and provides air to help a plant grow. leaves help the plants breath, and also helps in releasing water vapor through pores called stomata.

What are the four possible gametes of an organism has the genotype KkMm?

Answers

Answer:

KM, Km, kM, km

Explanation:

Gametes, which are only produced during sexual reproduction, are formed as a result of meiosis. According to Gregor Mendel in his law of Segregation, alleles of a gene will separate into gametes in such a way that only one form of a gene (allele) will be present in each gamete.

In this question involving a dihybrid with genotype: KkMm, the allele combinations of the gametes that will be produced after meiosis are KM, Km, kM, km.

Carbon credits are used to a. rehabilitate tropical rainforests b. reduce the emission of volatile organic compounds (VOC's) c. regulate how much carbon dioxide a country can emit d. coordinate carbon sequestration activities​

Answers

Answer:

C. Regulate how much carbon dioxide a country can emit

Carbon credits regulate the maximum quantity of carbon dioxide that a country may emit. Thus, C is the best choice.

How do carbon credits work?

A marketable certificate or permit known as a "carbon credit" attests to the authorization of a specific amount of carbon dioxide emissions or the equal amount of another greenhouse gas.

Carbon credits are also called as the carbon offsets, which are licenses that allow the owner to emit a particular quantity of carbon dioxide or other greenhouse gases where the Carbon dioxide emissions or the some another greenhouse gas are allowed under one credit. The carbon credit is a part of the so-called cap-and-trade system.

A few typical examples of initiatives are garbage management, the development of renewable energy, the use of farming techniques that store carbon, and reforestation.

Therefore, the correct option is C.
