Is the answer to this question.
A) The sperm cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.
B) The egg and sperm cells contribute equal amounts of mitochondrial DNA to the zygote.
C) The egg cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.
D) The sperm cell donates most of the DNA in the nucleus to the zygote, including mitochondrial DNA.
Answer:
The answer should be C
Explanation:
The egg contributes all the cytoplasm and organelles to the zygote. The sperm only contributes one set of chromosomes.
The typical sperm midpiece contains approximately 50-75 mitochondria with one copy of mtDNA in each. This represents an 8- to 10-fold decline in copy number during spermiogenesis.
Answer:
Excessive consumption is understood as an uncritical purchase. Thus, people who buy compulsively do not analyze the social and personal consequences of the purchase.
Explanation:
The warning about the risks of overpopulation has been the subject of books and discussions for many decades. Today the imbalance caused by overconsumption generates international debates, conferences, targets for reducing greenhouse gases, water consumption, installation of clean energy, among other internationally announced commitments.
This is because excessive consumption is made at the expense of natural resources. The more industrialized products are manufactured, the more natural resources are consumed. The more we buy these products, the more they are manufactured.
In view of the improvement in the quality of life and the higher gains, the population consumes a lot and directly interferes in the extraction of resources. In the consumption level data between rich and poor countries, the disparity in which the former vastly outweighs the latter is clear. Not to mention that rich countries encourage the extraction of resources in underdeveloped countries to meet their needs, since their resources have been depleted for a long time.

O the G2 phase.
mitosis.
The G2 phase of the cell cycle is when rapid cell growth in preparation for cell division occurs. This is after DNA replication and before mitosis.
Rapid cell growth in preparation for cell division occurs during the G2 phase of the cell cycle. The cell cycle is a four-stage process consisting of the G1 phase (gap 1), the S phase (synthesis), the G2 phase (gap 2), and mitosis. During the G1 phase, cells grow and prepare for DNA replication which happens in the S phase. In the G2 phase, the cell experiences rapid growth in preparation for cell division, cell size increases dramatically, and proteins necessary for cell division are synthesised.

b. Phospholipids
c. Glycogen
d. Glucagon
Answer:
C. Glycogen
Explanation:
When the food made of carbohydrates is broken in the organism, it creates glucose, which is a type of sugar that the body uses as a form of energy. The amount that is not used gets stored in various tissues of the body, but the places where the glycogen is stored in larger amounts are the liver and skeletal muscle.
Answer:
Glycogen
Explanation:
Glucose is used primarily as a source of energy and as such it has to go inside the cell. Excess glucose that is not immediately needed as a source of energy is combined into long strands of clucose units called glycogen and it is stored in the liver and skeletal muscle tissue. Glycogen is later broken dowin into its constituent glucose units and used as a source of energy when needed.
