Explanation:
Write a few sentences about how being small helps cells survive, and being made of many small cells help large organisms maintain homeostasis?
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.

Explanation:
how are the human senses connected with memory
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
Energy can change in two different ways. It can undergo a transfer, or it can undergo a transformation. For each of these examples of how energy is changed, write the correct answer in the blank.
In photosynthesis, solar energy undergoes a _______ when it changes from light energy to chemical energy. When the sun warms Earth’s surface, thermal energy is ___________ to land and water.
Answer:
Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.
While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
Explanation:
In a certain species of flowering plant, the purple allele P is dominant to the
Yellow allele p.
A student performed a cross between a purple-flowered plant and a
yellow-flowered plant. When planted, the 146 seeds that were produced from the
cross matured into 87 plants with purple flowers and 59 plants with yellow
flowers.
Calculate the chi-square value for the null hypothesis that the purple-flowered
parent was heterozygous for the flower-color gene. Give your answer to the
nearest tenth.
Answer:
3.4
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.

what is the difference of the atomic masses of the heaviest and lightest elements in the table?
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.

how does the sodium atom bond to the chlorine atom ?
Explanation:
It is happening when a sodium atom loses an electron to a chlorine atom and because of that sodium atom is becoming a positive sodium ion and the sodium ions and chloride ions form an ionic lattice.
Sodium - Na
Chloride - Ch
Sodium and Chloride are both elements that cannot be found separately and free in nature but they are found as bonded together.

5. What is the response of an ectotherm, such as a lizard, when it encounters cold temperatures?
It will move to a warmer spot.
It will remain in the cold environment.
It will run toward the stimulus.
It will become hungry.
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.
Explain how autotrophs obtain their energy to make their own food, and list at least three examples of autotroph organisms.
Answer:
Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy.

What causes the sinking of water in the northern Atlantic Ocean, which helps to drive the Ocean Conveyor Belt?
a.) The high salinity from the south warms and becomes less dense.
b.) The high salinity from the south cools and becomes denser.
c.) The low salinity from the south gains salt and becomes denser.
d.) The low salinity from the south loses salt and becomes less dense.
Answer:
the answer
proberbaly C or B
Answer:it's B or C
Explanation:
In cold regions, such as the North Atlantic Ocean, ocean water loses heat to the atmosphere and becomes cold and dense. When ocean water freezes, forming sea ice, salt is left behind causing surrounding seawater to become saltier and denser. Dense-cold-salty water sinks to the ocean bottom.
Which of the following is not a true statement about seed bearing plants?
The wind and animals can plant the seed in different locations.
Some seed bearing plants produce flowers.
Seed bearing plants produce spores.
Some seed bearing plants produce cones.
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.
