Which of the following is NOT accurate concerning ionization?
O In the compound MgCl2, Cl gains an electron to become negative.
O In the compound NaCl, Na loses an electron to become positive.
When an atom loses an electron, it becomes negatively charged.
When one atom loses electrons, another must gain electrons.
O lonic bonds form between ionized atoms.

Answers

Answer 1

lonic bonds form between ionized atoms.

Ionic bonds, also known as electrovalent bonds, are a type of linkage created in a chemical molecule by the electrostatic attraction of ions with opposing charges. When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond of this kind is created. If an atom gains electrons, it becomes a negatively charged ion (cation), while if it loses them, it becomes a positively charged ion (cation) (anion). Following is a quick discussion on ionic bonds. Ionic or electrovalent compounds are produced via ionic bonding, and the compounds generated between nonmetals and alkali and alkaline-earth metals serve as the best examples of this type of compound.

They line up with the duplicated chromosome one on top of the other. D. They line up with the chromosome from the same parent.​

Answers

Is the C. They line up with the duplicated chromosome one on top of the other

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.

Therefore, the correct option is C.

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.

Answers

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.

Carbapenems are b lactam antibiotics, as are penicillins and cephalosporins, which work by inhibiting cell wall biosynthesis in bacteria.

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.

Answers

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.

What is the scale of the model?
A. 1:1
B. 1:25,000
C. 10:25
D. 2,500:1

Answers

Answer:

B

Explanation:

I guessed and I got it correct

The scale of the model is 1:25,000. So, the correct option is B.

Scale models are used to represent things or places at a smaller, more manageable size while maintaining proportionality. They are often employed in many different disciplines including geography, engineering and architecture.

By comparing the length of the model to the length of the actual river, one can estimate the scale of the model.

The scale can be determined by dividing the length of the actual river by the length of the model, where the model is 1 m long and the actual river is 25,000 m long:

Scale = Length of actual river / Length of model

Scale = 25,000 m / 1 m = 25,000

Therefore, the scale of the model is 1:25,000. So, the correct option is B.

A compound is a substance formed by chemical bonding of two or more elements in definite proportions by weight. This means that chemical elements combine chemically via bonds to form compounds.

However, the properties of compounds are different from the properties of the elements that form them because elements in a compound combine and become an entirely different substance with its own unique properties.

how does the cycle of matter and energy flow through ecosystems relate to interactions occurring in the ecosystem?​

Answers

Decomposers receive matter and energy from dead producers, consumers, and the waste they make. The matter is converted back into inorganic forms by decomposers so that it can be recycled into the ecosystem.

So, the energy that comes from sunlight entering an ecosystem eventually leaves the ecosystem as heat.

Energy and materials are transformed from one form to another in ecosystems.All of the objects in that environment, both living and nonliving, are referred to as matter. Decomposers then break down the nutrients and living matter that have been passed from producers to consumers. Energy is transported between organisms in food webs from producers to consumers as decomposers break down dead plant and animal debris.
