The ability of a specific tissue or organ to respond to the presence of a hormone is dependent on ________.

1 answer:

7 0

The correct answer is "<span>the presence of the appropriate receptors on the cells of the target tissue or organ".

Hormones are chemical messengers that work to modify the target cell's actions. Hormones work by attaching to its appropriate receptor, then the receptor will be activated and signal transduction will take place. Signal transduction mechanisms will eventually activate a protein kinase which will phosphorylate a certain protein (usually a promoter for transcription) which will then start the production of a certain protein with a specific function.

For instance, insulin is a hormone. Insulin will then bind to muscle and adipose cells which will activate signal transduction mechanisms that will eventually lead to the translation of the glucose receptor and channel proteins which will increase the uptake of glucose in the blood stream and lower the blood glucose levels.</span>

Maurinko [17]

The correct answer should be A. spores

Ferns don't have seeds and they reproduce using spores. Cones have seeds in them and seeds fall out. Pollen enters a flower and then the flower becomes a fruit. This is sexual reproduction of plants. Since ferns don't have this, they have to reproduce with spores.

A good example of homeostasis would be: darkening a room makes it easier to sleep. ingesting too much alcohol leads to vomiting.

solmaris [256]

Homeostasis is a self-regulating technique by which systems in the body maintain stability and tend to adjust to optimal conditions which are essential for survival. Thereby, the role of homeostasis is to help the body maintain constant internal environment. A good example of homeostasis would be ‘drinking excess alcohol causes vomiting’.

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

zhannawk [14.2K]

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.
