Answer:
Oxygen
Explanation:
The formula for cellular respiration is oxygen + glucose -> water, carbon dioxide, energy. You can already cross out A and D because they aren't in the formula, so you have two left, water and oxygen. The reason why it is oxygen and not water is because without oxygen you can't even have water. also, I just got this right on my test :-)
<span>An organism with a cell wall would most likely be unable to take in materials through phagocytosis. This is a process where phagocytes and amoeboid protozoans ingest bacteria and other material. The cell has to bind to the things that it wants to ingest on the cell surface and draw it inward while engulfing around it. It can’t happen unless the cell is within physical contact of the particle it wants to ingest.</span>

Heterozygous Red- Rr
Homozygous Red-- RR
Homozygous white-- rr
Monohybrid cross- Rr
Recessive allele- homozygous white i.e rr
Explanation:
Heterozygous have 2 different alleles of a gene as both Red and white alleles are present in the example Rr.
Homozygous: If the 2 alleles at a locus is same then they are homozygous, it can be dominant as RR or recessive as rr.
Recessive gene are the ones that can be masked by the dominant genes as red is dominant on white.
Monohybrid cross is the result of cross between the individual having either homologous dominant or recessive genes or genotype. The result is generally masking the recessive allele resulting in dominant phenotypic trait but the genotype changes.
From the example given in question:
A cross between dominant red as RR
and a cross between recessive white as rr
The punnet square shows:
r r
R Rr Rr
R Rr Rr
it can be seen that all progeny are red but genotype changed to heterozygous red as Rr
The answer is True. These species do well in stable environment. They have a long life span and produce few offsprings in their lifetime. Their offspring are large and more energy is invested in the individual rather than the numbers. Individuals can reproduce more than once in their lifetime unlike r-selected species that reproduce once.
