the critical factor that determines gender during development is ________.

Answers

Answer 1

Answer:

the SRY gene.

Explanation:

The SRY gene was found within the minimum region of Y-specific DNA required for male development. Confirmation of its role was found by the analysis of XY female patients with mutations within this gene. A mouse has been an important working model to study the process of mammalian sex determination.

b. Which types of reproduction are followed in sugar cane plant and in mango tree?

Answers

Sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.

Sugar cane is usually reproduce by using asexual reproduction i.e. by the use of pieces of stem of sugar cane called setts that contain at least one node. It is necessary that these cuttings contain a node because when they are placed and covered in the ground, primary roots arise from these nodes.

While on the other hand, the mango trees can be propagated both by sexual and asexual reproduction. Sexual reproduction involves the fusion of male and female sex cells during flowering stage. Grafting, Cutting, Layering and Budding are the asexual means for the propagation of mango tree.

Among these the grafting technique is considered as the most suitable method of vegetative propagation of mango so we can conclude that sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.

Frequent earthquakes in an area may indicate

Answers

Earthquakes occur along fault lines, cracks in Earth's crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose

Frequent earthquakes in an area indicates that there are tectonic plates boundaries and there is sudden regression of underground rocks. Through the areas when there is sudden movement and dynamic stress along with the sudden triggering.

What are tectonic plates ?

Tectonic plates are larger pieces of earth's crust  and uppermost mantle. Tectonic plates movement cause the earthquakes to occur.

The other types of earthquakes are that of volcanic earthquakes, induced earthquakes and collapse earthquakes.

Therefore, earthquakes are mainly due to various conditions and other environmental activities that are not under control.

Answer:

A true understanding of the physiology of these bacteria and their roles in ecology, host health, and natural product production requires their cultivation in the laboratory. Recent advances in growing these species include coculture with other bacteria, recreating the environment in the laboratory, and combining these approaches with microcultivation technology to increase throughput and access rare species. These studies are unraveling the molecular mechanisms of unculturability and are identifying growth factors that promote the growth of previously unculturable organisms. This minireview summarizes the recent discoveries in this area and discusses the potential future of the field.

Answers

Answer:

Asthma and COPD are both chronic lung diseases. COPD is mainly due to damage caused by smoking, while asthma is due to an inflammatory reaction. COPD is a progressive disease, while allergic reactions of asthma can be reversible.With asthma, the swelling is often triggered by something you're allergic to, like pollen or mold, or by physical activity. COPD is the name given to a group of lung diseases that include emphysema and chronic bronchitis. Emphysema happens when the tiny sacs in your lungs (called alveoli) are damaged.

Answer:

Agriculture gave people the opportunity to create civilizations, fight hunger and work to combat challenges in population growth and climate change.

Explanation:

Another positive development in farming is the rapid expansion of farmers markets. Farmers markets allow small farmers to interact directly with consumers.
