If you push down an effort distance of 1.5m using an effort force of 60N, the box will rise distance of 0.9m.
To lift a 100N box onto a shelf. If we push an effort distance of 1.5m using an effort of 60N. The 100N box will rise up by a distance H.
This distance d can be calculated,
Using law of conservation of energy,
As there is no external force on the body the concept of conservation of energy can be used here,
It means that the applied energy will be equal to the output energy in the ideal conditions.
So, we can write,
Energy(applied) = Energy(Output)
mgh = MgH
Where,
mg is the effort force of 60N,
Mg weight of the box to be lift which is 100N,
h is the effort distance of 1.5 meters and,
H is height by which the box will rise.
Putting all the values,
60×1.5 = 100 × H
H = 90/100
H = 0.9m
The 100N box will rise upto a distance of 0.9 meters.

Explanation:
consider the bacterium thiomargarita namibiensis. imagine you are comparing two individuals that are the same size. individual 1 has a vacuole that is twice as large as the other, individual 2. which of the two would you expect to have a higher surface area-to-volume ratio for its membrane relative to its cytoplasm?
When the vacuole size for individual 1 is twice as large as individual 2, individual 1 will have higher surface area-to-volume ratio for its membrane relative to its cytoplasm.
Vacuole is the membrane bound cell organelle more prominent in plant cells. The vacuole is known to increase the surface area-to-volume ratio of the cell. Therefore larger the vacuole, larger is the surface area-to-volume ratio of that cell.
Membrane is the outer layer of the cell and cell organelles. It is made up of the lipid bilayer. It is very essential to separate the components of the cell from each other. Membrane is selectively permeable.

Mammals have a large amount of parental care, where one or both parents assist with the nurture of the newly-born offspring. Female wolves nurse and protect their pups for months. Chimpanzee offspring are cared for by the parents for several years. Although mammals have fewer offspring per reproductive event than fish, reptiles, and amphibians, their survival throughout their juvenile period is much higher. However, there are a few species of tropical frogs that lay eggs, but both parents tend to care for the offspring after they hatch. The male frog guards the eggs while the female frog assists in feeding the larvae after they hatch. Based on the passage, what makes a researcher infer that the survival rates are higher for tropical frogs than other frog species in general?
Answer:
Biparental care allows the energetic demands to be shared between both parents, which can improve the number of surviving offspring
Explanation:
when a molecule of oxygen moves from outside of a eukaryotic cell to eventually be reduced by complex iv of the electron transport chain, how many phospholipid bilayers does it need to cross?
Answer: You, like many other organisms, need oxygen to live. As you know if you’ve ever tried to hold your breath for too long, lack of oxygen can make you feel dizzy or even black out, and prolonged lack of oxygen can even cause death. But have you ever wondered why that’s the case, or what exactly your body does with all that oxygen?
As it turns out, the reason you need oxygen is so your cells can use this molecule during oxidative phosphorylation, the final stage of cellular respiration. Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
So, where does oxygen fit into this picture? Oxygen sits at the end of the electron transport chain, where it accepts electrons and picks up protons to form water. If oxygen isn’t there to accept electrons (for instance, because a person is not breathing in enough oxygen), the electron transport chain will stop running, and ATP will no longer be produced by chemiosmosis. Without enough ATP, cells can’t carry out the reactions they need to function, and, after a long enough period of time, may even die.
In this article, we'll examine oxidative phosphorylation in depth, seeing how it provides most of the ready chemical energy (ATP) used by the cells in your body.
Overview: oxidative phosphorylation
Simple diagram of the electron transport chain. The electron transport chain is a series of proteins embedded in the inner mitochondrial membrane. In the matrix, NADH and FADH2 deposit their electrons in the chain (at the first and second complexes of the chain, respectively). The energetically "downhill" movement of electrons through the chain causes pumping of protons into the intermembrane space by the first, third, and fourth complexes. Finally, the electrons are passed to oxygen, which accepts them along with protons to form water. The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

3. What is the rarest hair color?
4. Why?
Answer:
1. Lighter in Color
2. Less Melanin
3. Red
4. Recessive genetic trait = necessary for both parents to carry the gene, whether or not they themselves are redheaded
Explanation:
Hope this helps.
Answer:
Explanation:
1. Lighter colored eyes like blue, hazel and green
2. Lighter colored eyes like blue, hazel and green have less of a pigment called 'melanin' than brown eyes do. Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.
3. Natural red hair
4. Natural red hair is the rarest hair color in the world, only occurring in 1 to 2% of the global population. Since red hair is a recessive genetic trait, it is necessary for both parents to carry the gene, whether or not they themselves are redheaded. Due to this there are more people who carry the redhead gene, than there are people with red hair.

The correct answer is option D: ribosomes translate DNA code to RNA code.
During protein synthesis, ribosomes translate DNA code to RNA code.
Universally, ribosomes are responsible for the synthesis of proteins through the translation of genetic information with the help of mRNA as they code particular amino acids which are the key units of protein synthesis.
These are manufactured as a result of the processing of genetic code into messenger RNA i.e. mRNA through triplet RNA basis known as codons.
Moreover, ribosomes also function as catalysts to accelerate the process of protein formation by continuously supplying amino acids to the polypeptide chain.
During this reaction, transfer RNA i.e. tRNA server as a carrier of amino acids to ribosomal sites where translation of DNA code to RNA code occurs for protein synthesis.

How many cells are there are each of the beginning of the cell cycle?
There is just one cell at the start of cell division or the cell cycle.
A mother cell divides twice, once through mitosis to produce two daughter cells and once through meiosis to produce four daughter cells.
What are cell division and cell cycle?The cycle of a cell's growth and division entails a variety of processes. A cell spends the majority of its time, known as interphase, developing, duplicating its chromosomes, and preparing to divide. The cell continues its division process through mitosis after exiting interphase. Each of the freshly produced cells, known as daughter cells, enters its own interphase and initiates a new cycle of the cell.
The two different cell division processes are meiosis and mitosis.
During the mitotic cell cycle phase, which is also known as division, replicated chromosomes are split into two new nuclei. Cell division known as mitosis creates genetically identical cells with a conserved chromosome number.
In sexually reproducing mammals, meiosis is a special type of germ cell division that produces gametes, such as sperm or egg cells. After two rounds of division, four cells with a single copy of each chromosome are created.
