There is no correlation between number of chromosomes and size, nor is there a correlation between number chromosomes or genes and complexity. More chromosomes or genes aren't needed to maintain a larger animal because there is a copy of the genome within each cell.

What organ beats faster if you are smaller?

The heart beats faster in smaller organisms because they have a higher metabolic rate and need more oxygen and nutrients to sustain their bodies compared to larger organisms. This results in a faster heart rate to circulate blood efficiently.


What is one benefit to an organism of being large?

It takes less cells to do the job. If you cut yourself, then your body can send less cells to heal the wound compared to when the cells are smaller. You need more cells when you are smaller then when you have the larger cells.


How do organisms add more cells to their bodies?

Adding more cells


Why do gametes have half the number of chromosomes as somatic cells?

Since you need 46 chromosomes total to function properly, and each of your parents have 46 chromosomes, you need to get 23 chromosomes from each of your parents in order to have the correct number of 46 chromosomes. You get 22 somatic chromosomes (autosomes) and 1 sex chromosome from each parent. Of course, during oogenesis or spermatogenesis, there could be nondisjunction, resulting in you receiving more or less chromosomes than you should. An example of this is Down Syndrome, where you receive an extra copy of Chromosome 21 from either parent. However, generally you will only receive 23 chromosomes from each parent (through their gametes) so that when they combine, you will have the correct 46 chromosomes. That is why gametes (haploid) have half the number of chromosomes as somatic cells (diploid).


What role did cyanbacteria play in the evolution of life on earth?

The role of raising atmospheric oxygen to so high a level that multicellular and complex organisms could evolve. Oxidative phosphorylation generates the energy through ATP that larger and more complex organisms need.

Why do reproductive cells need to have half the normal number of chromosomes?

Humans and other organisms that reproduce sexually need to have half the normal number of chromosomes to make sure their offspring have the same number of chromosomes as they do - the father and mother each contribute half of their chromosomes (sperm and egg).


Do more complex organisms need more energy than simpler organisms?

Yes, generally more complex organisms require more energy to support their increased metabolic demands. This is because complex organisms have more specialized cells and tissues, perform more complex functions, and require larger and more efficient organ systems to sustain their body functions.


Will a population grow larger if it has a large supply of food?

no it will not because it depends on how many males and females there are in that group


Why has bacteria only one chromosome but amoeba has several?

Because amoebas are more advanced in their design then bacteria, therefore they need the chromosomes to encode that information. Examples are like how amoebas have membrane bound nucleus and many organelles, in contrast bacteria lack these things. Also amoebas are much larger in size. However amoebas have many very small chromosomes, while bacteria have one larger one. So the amount of information on each chromosome is also in large contast

Why do larger organisms need a circulatory system and amoeba do not?

We are eukaryote which means are cells are more advanced than there's. And since we have more cells than a amoeba. Our cells carry oxygen to the brain and other organs in the body. A amoeba dose not have a brain. So it doesn't need a circulatory system.


Are all organs multicellular?

(; No, there's some things that are unicells. Humans, and larger types of organisms are multicellular. Small organisms are unicells because their body ain't large enough and they don't need alot of cells like us. ;)


Do larger seeds need more room to grow?

usually


What might happen if you go on buying more and more cars?

You will need a larger garage.


Why does respiration rate decrease with increased mass?

As an organism's mass increases, its metabolic rate typically decreases because larger organisms have a lower surface area-to-volume ratio, resulting in less heat loss per unit mass. This leads to a reduced need for oxygen, resulting in a slower respiration rate. Additionally, larger organisms tend to have more efficient respiratory systems that can adequately supply oxygen to the body without the need for rapid breathing.


Why do organisms need to be able to reproduce?

They don't HAVE to but if most don't, there will no more left.


How it effect the organisms if the pollution continues?

The organism will either have to adapt or die. For most larger, more complex life forms it is difficult to adapt. They are actually quite fragile and need a specific environment. It is usually the humbler forms that adapt.
