The order the organisms will appear during primary succession would be lichens -->mosses-->grasses and annual flowers--->bushes and shrubs-->trees.
What is succession?Succession refers to the gradual changes to the community of organisms in an ecosystem until a stable community is reached.
Succession can be primary or secondary.
Primary succession happens when a community that has never held any life before gets newly colonized by life.
Secondary succession happens when a community that already holds life experiences a major disturbance and needs to start adjusting itself to resume changes again.
The colonizers in primary successions are called pioneer species. Due to limited nutrients and soils, pioneer species must have low requirements.
Thus, the order of appearance during primary succession would be the order or increase in growth requirements.
lichens -->mosses-->grasses and annual flowers--->bushes and shrubs-->trees.

(copper has the most thermal conductivity with 400. and copper once again has the most electrical conductivity with 5.9x107S/m)
Conductivity is the measure of the ease at which an electric charge or heat can pass through a material. A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy.
What is thermal conductivity examples?The physical property how much a body can be sized for thermal conductivity. Good thermal conductors have a high value of thermal conductivity, while insulators have low thermal conductivity. Another factor that depends on thermal conductivity is the thermal sensation.
Thermal conduction, also called thermal diffusion, is a type of heat propagation that takes place in a material medium due to the agitation of molecules. As the temperature of a solid body increases (either through heating or contact with another), the kinetic energy also increases.

A) explosive with a pyroclastic flow B) non-explosive with a pyroclastic flow C) explosive with pyroclastic and lava flows D) non-explosive with a lava flow
PLEASE HELP GIVING BRAINLIEST TO FIRST CORRECT ANSWER
A cinder cone volcano easily erodes because it is made of ash and other volcanic debris. This indicates that its eruption is primarily explosive with a pyroclastic flow.
Volcanoes with cinder cones are the most basic. They are made of lava chunks and blobs that were ejected from a single vent.
A single vent is surrounded by a conical formation of ash, tephra, and solidified lava called a cinder cone. After being ejected into the air from the vent, volcanic debris breaks apart and falls to the ground, forming the cone. As the ash and lava cool and solidify, they form a cone around the vent.
The height of a cinder cone can range from 10 to hundreds of meters, and its summit frequently features a bowl-shaped crater. They differ from spatter cones, which are made of agglomerated volcanic bombs, in that they are made of loose pyroclastic material (cinder or scoria) and hence eruption is primarily explosive with a pyroclastic flow.

Chromosomes line up differently in meiosis compared to mitosis as they line up with the duplicated chromosome one on top of the other. Therefore, the correct option is C.
During mitosis the chromosomes align differently than during meiosis. Homologous chromosomes pair up and join during the first stage of meiosis, known as prophase I. Two sister chromatids, which are identical copies made by DNA replication, make up each homologous chromosome. A quadrivalent or bivalent is the name of the structure formed by these paired homologous chromosomes.

Carbapenems are b lactam antibiotics, as are penicillins and cephalosporins, which work by inhibiting cell wall biosynthesis in bacteria. In recent years, more cases, mostly in patients who have been hospitalized for a long period of time, of bacteria showing resistance to Carbapenems have been reported. In these patients, this drug could no long control bacterial infections. Check ALL the statements that are correct:
Question 1 options: Bacteria that are resistant to Carbapenems did not exist before these drugs were used.
Carbapenems are the selecting agent Bacteria become resistant only after they come into contact with Carbapenems
This development of drug resistance by bacteria is an example of evolution
Non-resistant bacteria become resistant strains via mutation
The rate of mutation (to resistant strains) is always increased by the use of Carbapenems
The rate of survival among resistant bacteria is always increased by the use of Carbapenems
The change from non-resistant to resistant bacterial strains are not due to changes in genes.
Cabapenem-resistant bacteria may come into existence if Carbapenems are not used.
Only once bacteria come into touch with carbapenems do they develop resistance. This bacterial drug resistance is an illustration of how non-resistant bacteria can mutate into resistant strains.
The original "carbapenem," thienamycin, would become the parent or model compound for all subsequent carbapenems. Recent research demonstrates unequivocally that carbapenem resistance is growing globally. In particular when porin losses occur, excessive synthesis of weak carbapenemases as CMY-10 and PDC Beta-lactamases might result in carbapenem resistance. Gram-positive bacteria develop resistance to carbapenems and other beta-lactam antibiotics through mutation-derived modifications to their PBPs, whereas Gram-negative bacteria frequently enlist the help of additional defense mechanisms to combat the effects of these drugs.

Examine the data shown in Figures 2 and 3. Carefully compare the DNA methylation profiles from the 3-year-old twins versus the 50-year-old twins and summarize your observations. Which set of twins (3-year-old or 50-year-old) have the most similar DNA methylation profiles? Provide a brief explanation of your observations.
A DNA base is altered biochemically during DNA methylation, which typically takes place during gametogenesis and after fertilization.
The DNA methyltransferases DNMT1, DNMT3A, and DNMT3B keep methylation marks in tact after each cell division. Although the majority of methylation marks are stable, there is typically 10% to 20% variation over time. Ly cytosine undergoes enzymatic 5-carbon methylation. DNA methylation represents the best characterized form of epigenetic modification. DNA methylation is written onto the genome by two methyltransferases, known as Dnmt3a and Dnmt3b.These enzymes catalyze the addition . Aging is often marked by the establishment of global hypomethylation and regions of CpG island hypermethylation. These changes in the epigenetic landscape may contribute to aging by adversely affecting genomic stability and gene regulation. Thus, DNA methylation has its affect on aging and thus should be observed carefully.Learn more about DNA here:

1. What is the change in volume from 22 degrees Celsius to 23 degrees Celsius?
Answer:
According to Charles' Law.
Volume is directly proportional to Temperature.
So if temperature increases from 22degree Celsius to 23degree Celsius, then Volume will increase from its initial.
The change in volume from 22 degrees Celsius to 23 degrees Celsius is seen because the change in temperature is directly proportional to the change in volume and the volume increases.
What is the role of temperature?The role of temperature is important as the low temperature changes the state that is from the liquid to the solid while the high temperature changes the state of matter that is from the liquid to the gas. The temperature of the earth is continuously increasing, so that the polar ice is melting and the water level on the earth is increasing. The increase of one degree is significant in the earth as the ice melts into the water, and that harms the animals and plants present in the different habitats.
Hence, the change in volume from 22 degrees Celsius to 23 degrees Celsius is seen because the change in temperature is directly proportional to the change in volume and the volume increases.
