Answer:
A) Reaction X used a catalyst
Explanation:
Reaction X has a lower activation energy and the most likely cause of this would be a catalyst.
Answer:
Together these reactions allow cells to make and store energy and help regulate atmospheric concentrations of carbon dioxide and oxygen.
Explanation:
Photosynthesis and cellular respiration are complementary biochemical reactions. Photosynthesis requires the products of respiration, while respiration requires the products of photosynthesis. Together these reactions allow cells to make and store energy and help regulate atmospheric concentrations of carbon dioxide and oxygen.
Through meiosis, diploid parents produce haploid cells called gametes. The gametes, through sexual reproduction, then meet and join into one cell called a zygote that is diploid.
The zygote then develops into a diploid organism with genetic traits from both parents.
Answer:
1. b. Crista is s constituent part of mitochondrion.
2. c. Gobi complex and nucleus are separate structures with no particular relationship to each other.
Explanation:
The crista is an integral part of the mitochondria. As you already know, mitochondria is a cytoplasmic organelle. it has two members that delimit it, the outer membrane is completely smooth, however the inner membrane is composed of numerous folds, that are called crista, and that spread through the interior of the mitochondria. These crista have as main function to increase the surface of the inner membrane.
The Golgi complex is a cytoplasmic organelle, as is mitochondria. The nucleus, however, is a cell structure, it is totally separated from the golgi complex and there is no particular relationship between these two structures.
The golgi complex participates in the storage and distribution of substances in the cell, while the nucleus is responsible for housing and protecting genetic information.
