Please Answer this one MCQ. I am in trouble please help ..​

Answer:

The lightest chemical element is Hydrogen and the heaviest is Hassium. The unity for atomic mass is gram per mol. ... There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals.

Explanation:

The difference of the atomic masses of the Uranium which is the heaviest and hydrogen which is the lightest element in the table is 237.

The lightest element in the periodic table is hydrogen having atomic mass of 1 amu whereas Uranium is the heaviest element present in the periodic table having atomic mass of 238 amu. The difference between atomic masses of the heaviest i.e. uranium and lightest element i.e. hydrogen in the table is 237. In hydrogen, there are only one proton and no neutron is present inside the nucleus while on the other hand, in uranium there is 92 protons and 146 neutrons are present in the nucleus which make it heaviest element.

Answer:

During every moment of an organism's life, sensory information is being taken in by sensory receptors and processed by the nervous system. Sensory information is stored in sensory memory just long enough to be transferred to short-term memory. Humans have five traditional senses: sight, hearing, taste, smell, touch

Explanation:

If the purple flower is heterozygous:

                Pp    x    pp

            Pp   Pp   pp   pp

the expected ratio of purple flower offspring to yellow flower offspring would be 50:50.

Chi square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = expected frequency.

phenotype            O              E                 Chi square

purple                   87             73                [tex]\frac{(80-73)^2}{73}[/tex] = 0.67

yellow                   59             73                [tex]\frac{(59-73)^2}{73}[/tex] = 2.68

Total = 0.67 + 2.68 = 3.35 to the nearest tenth = 3.4

Degree of freedom = 2 - 1 = 1

Critical Chi square value (alpha = 0.05) = 3.84  

SInce the critical Chi square value is greater than the calculated value, the null hypothesis is accepted.

Answer: It will move to a warmer spot.

Explanation:

An ectotherm will move to a warmer spot if they found themselves in cold temperatures because they are not tolerating good cold temperatures. If they do not have any other options they will run toward the stimulus which means that they will try to bury themselves and hide from cold temperatures and in that way they will have to remain in the cold environment.

Answer:

Seed bearing plants produce spores is not a correct statement.

Explanation:

The plants have different mechanisms of reproduction. The more primitive plants, for example, tend to reproduce through spores that are dispersed over a wide area by the wind. The plants that evolved later in history tend to produce seeds through which they reproduce, and the seeds can be dispersed in numerous different ways.

Some of the plants that bear seeds produce flowers, some fruits or vegetables, while some cones. The reason why they produce such things is to be more attractive for animals because by eating or getting near them the animals manage to disperse the seeds over a wide area. The plants of this type that have the smallest seeds don't really need animals though, as the wind is able to easily pick up and move their seeds around with ease.

Answer: best guess: A. The wind and animals can plant the seed in different locations.

Answer:

It is important for the cell to be able to bring necessary nutrients immedriately where it needs to and to be able to dispose of harmful byproducts of the cell process. It is equally important to be able to regulate water concentration.

Answer:

For the first question, you have to first understand how cells work. Cells transport nutrients and water through their cell membrane, and it's their only way of transporting things they need in and out of their interior. Hence, a larger surface area would be best for cells to survive.

You might ask, but then why wouldn't it be better for cells to be bigger if a larger cell membrane is beneficial to their survival? After all, as the cell gets bigger, their cell membrane gets bigger too!

Unfortunately, you'd be forgetting one thing: the insides of the cell, otherwise known as the volume of the cell, grows too. So, it becomes a mathematical question at this point: imagine a cube. If you doubled it's side length, your surface area would grow by 4 times ([tex]2x \cdot 2x = 4x^{2}[/tex]), and your volume would grow by 8 times! ([tex]2x \cdot 2x \cdot 2x = 8x^{3}[/tex])

Hence, if the cell got bigger, it's volume would grow faster than the surface area, and the cell would start to build up carbon dioxide and other waste materials.

This is the main reason why being small helps cells survive. Of course, there are many other reasons, like compactness, efficiency and survivability, but this is the main reason.

Of course, if you're smart, you'd have already discovered one thing: this is exactly the reason for your second question as well. Since a large organism being made of one or few large cells would greatly decrease surface area-to-volume ratio, the efficiency would plummet and the large organism would die. Hence, many small cells would help large organisms maintain homeostasis.

Erosion is the process of destroying and destroying existing forms in relief.

Erosion is the destruction of the existing structural connections of the rock mass due to the action of exogenous forces and the change of its shape.

The term erosion in the elementary sense should mean changes in the surface layer of the soil relief, which occur as a result of rain, snow, frost, temperature differences, wind, and running water, or due to the work of anthropogenic factors.

Answer:

Barrier islands form in three ways. They can form from spits, from drowned dune ridges or from sand bars. Longshore drift is the movement of sand parallel to the shore caused by the angle of the waves breaking on the beach. When a storm such as a hurricane digs an inlet through the spit a barrier island is formed. Barrier islands are a specific type of island that lie parallel to the coastline of a larger mainland. They are separated from shore by a bay, lagoon or sound and because of where they are situated, they protect the coast from being directly impacted by storm waves or winds.
