I believe it is they are reactants because they’re present before the reaction. O2 and glucose are reactants in the cellular respiration process. The product is ATP
Answer:
Breathing out the carbon dioxide
Explanation:
Blood is the medium through which carbon dioxide is transported to the lungs from where it is exhaled out.
The Carbon dioxide produced in cells after respiration diffuses into the blood in exchange of oxygen delivered to the cells for further respiration. Blood while flowing through the lungs passes carbon dioxide to its alveoli which is then exhaled out and oxygen is inhaled from outside.
Hence, cell keep the carbon dioxide from building up in the cytoplasm and poisoning the cell by exhaling CO2.
Answer:
Option A, Acquisition
Explanation:
The first stage of learning is known as acquisition. It causes establishment of responses by pairing of Neutral stimulus, conditioning and un-conditioning stimulus. Once the association between a neutral stimulus and conditioned stimulus is established, the responses are acquired.
For example – If a bird is trained to pick a key whenever there is a sound of a bell, then after certain period of time an association will be established between the “ringing of bell” and “picking up of key” activity. Therefore, whenever the bird will hear the ringing sound it will search for key to be picked.
Thus, option A is correct.
Answer:
<em>C. The bird population moved into and adapted to many different environments on the Hawaiian Islands.</em>
Why:
<em>When a species </em><em>adapts</em><em> itself to new environments certain features will change, such as beak size, wing use, and even height, these are all changed depending on what the species does and needs to survive. These birds all changed food sources which made them have to adapt their beaks over time to new sources, and natural color to over generations camouflage themselves better from predators.</em>
<em>(Hope this was a good explanation.)</em>
Answer:
The question lacks options, the options are:
parents?
A.100% red/white-feather chickens.
B.50% white-feather chickens and 50% red/white-feather chickens.
C.33% white-feather chickens, 33% red-feather chickens, and 33% red/white-feather chickens.
D.25% white-feather chickens, 25% red-feather chickens, and 50% red/white-feather chickens
The Correct answer is D
Explanation:
According to the question, the hybrid chicken has a mixture of red and white feather phenotypes expressed at the same time. This tells us that the red and white alleles are CODOMINANT in the chicken i.e. none is dominant or recessive over the other.
Let's assume that (R) allele is the red feather colour while (r) allele is for white feather colour. Therefore, the red/white feathered chicken will have a Rr genotype. In a cross between two red/white feathered chicken (Rr), the following offsprings will be produced RR, Rr, Rr and rr
RR- Homozygous red feather d chicken (1/4 × 100=25%)
Rr- Hybrid Red/White feathered chicken (2/4 × 100=50%)
rr- Homozygous white feathered chicken (1/4 × 100=25%)
