Answer:

Chritsy must remove option A i.e "Is a transition metal"

Explanation:

Sodium is not a transition metal. It is a group  element. Transition metal have very high density and boiling temperature like chromium which is a transition metal. Sodium do not have high density and boiling temperature.

Hence the correct option to be removed is option A i.e "Is a transition metal"

Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, along  electromagnetic spectrum, wavelength increases, frequency decreases.

Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.

There is a relation between energy of wave. frequency of wave, and wavelength of wave

Mathematically,

E=hc/λ

where,

E = energy of electromagnetic wave

h is planks constant having value 6.67×10⁻³⁴js

c is speed of light that is 3×10⁸m/s

λ is the wavelength of electromagnetic wave

Wavelength is inversely proportional to frequency of wave. From left to right in electromagnetic spectrum, wavelength increases.

Therefore, along  electromagnetic spectrum, wavelength increases, frequency decreases.

Answer:

because of similar organs

Answer:

Photosynthesis is the process in which plants and autotrphs get their food and energy from. This process occurs in the choloplast, starting off when the plant recieves energy from the sun, carbon dioxide and nutrients and water from the soil. All this goes up to the leaves where the plant cells are. Here the choloplast process all the nutrients with the cholophyll (what gives plants their green color) and ir produces glucose (sugar) that is their main source of energy and oxygen. Plants use the glucose as a fuel and get rid of oxygen.

Answer:

"dog owners selectively bred dogs for desirable traits"

Answer:

Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind

The two common ways in which seeds are dispersed are through the wind and through animals such as insects. It is important for the seeds to be spread in different places and environment to produce more and more number of plants.

Seed dispersal is the mechanism through which seeds of the plant are transported to the new sites for germination and the establishment of new individual plants. Animals commonly mediate this process of seed dispersal, and consequently, the ultimate fate of seeds depends on their effectiveness as that of seed dispersers.

Because, many plants cannot walk around on their own and take their seeds to other places of the environment, they have developed other methods to disperse off their seeds. The most common methods of seed dispersal include wind, water, animals, explosion and fire.

Answer:

limited resources

Explanation:

Resources like infrastructure, land, water, food etc are essential to stay in any area. With limited infrastructure services the living quality of an area degrades. Like wise non availability of resources like water, land (or very costly land due to high demand) also degraded the living condition in any urban area.

Answer:

Chloroplasts and Mitochondria both evolved in primitive microorganisms as

they were able to make more use of available energy.

Explanation:

Endosymbiosis involved the engulfing of smaller microorganisms by a larger one. These engulfed organisms and their hosts both had distinct genetic lineages. Mitochondria and Chloroplasts generate large amounts of energy in the form of high-energy ATP or adenosine triphosphate through several steps, the electron transport chains, Krebs and Calvin cycles.

On average, the net gain of ATP from mitochondrial respiration surpasses the energetic gain from the ATP made via glycolysis.

Answer:

By measuring temperature and looking at the motion of the water in the cup, one can collect evidence to determine whether this system is at equilibrium

Explanation:

For any system to be in equilibrium there must be no transfer of heat and energy or motion between the system and the surrounding environment. If there is no change in the temperature and energy or motion of the cup of water, then it can be said that the system is in equilibrium.

Answer:

The most widely used method of calculating an average is the 'mean'. When the term 'average' is used in a mathematical sense, it usually refers to the mean, especially when no other information is given. Add the numbers together and divide by the number of numbers. (The sum of values divided by the number of values).

Explanation:

Arithmetic Mean by Direct Method - formula

∑i=1nf= Sum of all the frequencies. This is also denoted by N. ∑i=1nfixi= Sum of the product of frequencies and corresponding observations.
