A biotic factor can limit growth because for an example, if lions eat all of the zebras (for an example), what will other carnivores eat? There will be competition for food.
Answer:
The two structures used in membrane transport are 1 integral membrane protein 2 peripheral membrane protein.
Explanation:
The various protein present in the plasma membrane help the later to exhibit its function to transport various solute molecules and ions across the membrane.
Integral membrane protein such as Na+K+ATPase helps in the transport of Na+ ions inside the cell and K+ ions outside the cell against their concentration gradient.
Peripheral membrane proteins are present in water soluble region of either extracellular region or cytoplasmic region or both.Peripheral protein also helps in the transportation of various solute molecules .
Answer:
b) 25% is the right answer
Explanation:
A woman heterozygous for A blood group with genotype = Iᵃi
A man heterozygous for A with genotype = Iᵇi
so after cross between Iᵃ i x Iᵇ i
alleles man woman
Iᵃ i
Iᵇ IᵃIᵇ Iᵇi
i Iᵃi ii
so the offspring will be
25 % AB IᵃIᵇ 25 % A Iᵃi
25 % B Iᵇi 25 % O ii
Answer:
The population is decrasing
Explanation:
As we can see from the chart, the diversity of animals in Africa are being affected year after year. In 10 year gap 53,000 lions, 42,500 cheetahs and 12,500 zebras are dead and this is a dangerous sign.
Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun's energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. ... It's the green light reflecting that makes some leaves look green!
Also plants absorb energy from the sun by;
Photosynthesis is the process by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel. Here is how it works. The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun.
