A single fundamental similarity and or unity among all living organisms, is that all living organisms are composed of the basic units is life known as cells.
Answer:
The "reproductive handicap" in sexual reproduction can refers to that only half of the offspring will be female.
It means that a female undergoing asexual reproduction will have offspring with 100% of her DNA, while a female with sexual reproduction usually only transfers 50% of her genetic material to her offspring.
Answer:
ecological dominants
Explanation:
In an ecosystem, organisms of same and different species are usually found. However, some organisms appear too commonly than others in that particular ecosystem. These commonly observed organisms (plants and animals) due to their large numbers are called DOMINANT species. An ecological dominant species is that which numerically outshines its competitors in an ecosystem.
A species may be dominant because it is better adapted to certain processes than Its competitors e.g. getting resources, disease resistance etc. or even deters its competitors. Hence, they appear large in number. This is the case of the abundance of pinyon pine and juniper trees along the desert slope of the sierra nevada mountains in california. In that ecosystem, these two plants dominate, hence, will be referred to as ecological dominants.
Answer:
At what rate do the mitochondria of the cell need to convert glucose to usable
energy molecules to meet the high energy needs of the cell?
Explanation:
Organelles are organ-like structures found in cells. The are responsible for the specific actions carried out by each cell. Each organelle has its own specific role to play. However, missing or damaged organelles can have effects on the cells.
Mitochondria are organelles found in cells of all eukaryotic living organisms e.g animal, plants as they are responsible for the synthesis of energy in form of ATP. Since the cells being investigated in this question is a MUSCLE CELL, which is only found in animals, then an appropriate organelle must be investigated.
The appropriate to be asked to know if muscles cells are functioning properly is: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?.
Note that, other options are incorrect because muscle cells do not have chloroplast and cell wall, while ribosomes are not site for glucose production.
Endotherms can use metabolic heat to regulate body temperature; the temperature is high and stable, even with external fluctuations
