Which best describes oogenesis and spermatogenesis? A. During oogenesis, the cells become haploid after meiosis I, while in spermatogenesis, the cells become haploid after meiosis II.
B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.
C. In both oogenesis and spermatogenesis, the cells become haploid after meiosis II.
D. During spermatogenesis, the cells become haploid after meiosis I, while in oogenesis, the cells become haploid after meiosis II.

Answers

Answer 1

Answer: The answer is B. In both oogenesis and spermatogenesis, the cells become haploid after meiosis I.

Gametogenesis is a process in which gametes are produced. Oogenesis is a process in which egg cells are produced and spermatogenesis is a process in which sperm cells are produced. Both processes include meiosis.
Original diploid cell (primary oocyte or spermatogonium) has 46 chromosomes. After meiosis I, there are two haploid cells. After meiosis II, there are 4 haploid cells because meiosis II is similar to mitosis. The difference between spermatogenesis and oogenesis is that those 4 cells after meiosis II in spermatogenesis are all sperm cells, and in oogenesis only one of them is egg cell.

The United States' __________ was patterned after Germany's autobahn.a. flight network
b. streetcar system
c. cargo and mail transport
d. Interstate Highway System

Answers

The answer is D. Interstate Highway System. The United States envisioned a highway system that would allow for controlled access to the road with no stop lights and a higher speed limit. This would allow for a faster means of transportation for goods and people throughout the country. In modeling this highway system, the United States looked to the autobahn in Germany after seeing how successful it was.

the answer is d interstate highway system

Succession occurs when environmental factors affecting an ecosystem change. True or False

Answers

Answer: True

Succession is the phenomena in which changes in the biotic and abiotic factors of the environment leads to change in the ecosystem. A succession is a process in which a biological community is replaced by another biological community until a mature ecosystem is formed this process is influence by environmental factors. Primary succession is the primitive environment where no biotic community previously existed it is followed by secondary and subsequent succession were life forms develop and form an ecosystem. Some of the environmental factors are:

Topographical : These are the change in the region or habitat were succession occurs. Landslides, volcanic eruption, glacier melting etc. are the examples , as these topographical changes can bring reformation of the landscape. The disturbance caused by these topographical changes will allow the disturbance tolerant species to repopulate the habitat. This can be a transition from primary to secondary succession.

Soil : It is an abiotic factor.The growth of the plants requires suitable soil conditions. The type of soil will affect which species will inhabit the area. The soil moisture and pH greatly affect the number of plant species in an area.

Climate : It can influence the direction of succession. Climatic factors includes rain, wind etc. For example a region lacking proper rainfall the species will be tolerant to dry and drought conditions. The region with heavy rainfall, the species will be more tolerant to moisture. Wind being a climatic factor can cause wind erosion affect the soil quality. Wind can lead to heavy forest fires can therefore, wiped out community.

Succession takes place when environmental factors affecting an ecosystem change. Therefore, the given statement is true.

Succession refers to the process of ecological change over time in a particular area or habitat. It involves the progressive and predictable sequence of changes in species composition and community structure, leading to the development of a stable and mature ecosystem.

It can occur in both terrestrial and aquatic ecosystems. It is typically categorized into two main types: primary succession and secondary succession. It is a dynamic process.

Ben was training for a cross-country bicycle race. During his practice run, Ben's tire went flat and he fell off of his bike, cutting both knees. He was worried that he would not be able to compete in the race being held in two weeks, but his father told him not to worry: His knees would be healed by then. What process is responsible for new tissue growth and the healing of Ben's knees?a. mitosis
b. meiosis
c. duplication
d. transcription

Answers

The answer is (a.) Mitosis

Ben's cut on his knees will be healed because of mitosis. Mitosis is responsible for the new tissue growth for the healing of Ben's cut. Mitosis is referred as the fundamental process if life. In Mitosis, a single cell will grow and reproduce to two identical cells.
