Answer:
Deoxyribose
Explanation:
DNA stands for "deoxyribonucleic acid" because it has the sugar deoxyribose. It's named because it has one fewer oxygen than ribose. Be careful not to confuse the two sugars--ribose is in RNA, which stands for "ribonucleic acid."
Attached is a picture of the differences between the two sugars.
Answer:
Fungi are the eukaryotic, multicellular and heterotrophic organisms that are different from plant and animals.
The body of fungi consists of mycelium, fruiting body and spore. Mycelium is composed of threads like structure called hyphae. Fruiting body of fungi is the place where spore are produced. Spores are the reproductive elements of fungi through which new fungi is produced.
id help you but im in middle school not high
Answer:
Yes. You did it correctly.
Explanation:
The punnet square should be completed as follows:
T T
t Tt Tt
t Tt Tt
As the question says that the pollen carries the recessive alleles, hence the pollen should be carrying the alleles tt.
The question also says that all the offsprings produced are tall. Hence, the recessive male has to breed with a homozygous dominant female to get these results. The offsprings produced will be heterozygous dominant in this case.
Answer:
a. both oxygen and carbon dioxide
b. carbon dioxide only
c. carbon dioxide only
d. oxygen only
e. carbon dioxide only
f. oxygen only
g. oxygen only
h. oxygen only
Explanation:
This question is describing the gaseous exchange of carbon dioxide and oxygen that occurs during cellular respiration. The gaseous exchange occurs via a structure called ALVEOLI OR AIR SAC.
According to this question, the following statements in the question will be matched with whether it applies to oxygen only, carbon dioxide only, or both oxygen and carbon dioxide:
a. Both oxygen and carbon dioxide are diffused through the alveoli capillaries.
b. Carbon dioxide is the waste product of cellular respiration (excreted via the lungs).
c. Carbon dioxide have the ability to form carbonates (CO3²-) and are sometimes transported in that form.
d. Oxygen from the lungs diffuse into the alveoli during inhalation.
e. Carbon dioxide from the body tissues are carried by the blood into the alveoli in order to be transported out of the body.
f. Inhalation is the taking in of air (oxygen-containing). Hence, oxygen only enters alveoli during inhalation.
g. Oxygen is the necessary substance needed by cells in order to perform cellular respiration (aerobic).
h. Haemoglobin is an iron-based protein present in the blood cells. It possess affinity for oxygen and carries oxygen in the blood.
