"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."

SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.

Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

Answer:

The organelle that is not surrounded by a membrane but sits in the nucleus is called the nucleolus.

Explanation:

The organelle that is not surrounded by a membrane but sits in the nucleus is called the nucleolus. It is a small, dense structure that is responsible for producing ribosomes, which are essential for protein synthesis. Despite not being surrounded by a membrane, the nucleolus is separated from the rest of the nucleus by a distinct boundary, known as the nucleolus organizer region. This region contains specific genes that are involved in the production of ribosomal RNA, which is a key component of the ribosomes. The nucleolus also plays a role in regulating cell growth and proliferation.

Feedback interactions with the human body are essential because they play a crucial role in maintaining homeostasis, which refers to the body's ability to maintain a stable internal environment despite external changes.

These feedback mechanisms allow the body to detect and respond to deviations from normal conditions, ensuring that physiological processes remain balanced.

In the human body, feedback interactions typically involve a control system consisting of a sensor, a control center, and an effector. The sensor detects changes in the body's internal environment, such as temperature or hormone levels. The control center receives and processes the information from the sensor, determining the appropriate response. The effector then carries out the response, restoring or adjusting the body's conditions back to the desired set point.

Through feedback interactions, the body can regulate various processes, including body temperature, blood glucose levels, pH balance, heart rate, and hormone secretion, among others. These mechanisms enable the body to respond to internal and external stimuli, ensuring optimal functioning and promoting health.

Without feedback interactions, the body would be unable to detect and correct deviations, leading to imbalances and potentially harmful consequences. Feedback mechanisms are vital for maintaining the stability and overall well-being of the human body.

Explanation:

Organisms are classified based on their evolutionary history, genetic relatedness, and physical characteristics. While some organisms may share physical similarities, they may not be closely related genetically or have a common evolutionary history.

For example, the marsupial mole and African golden mole both have similar physical characteristics, such as a streamlined body and long snout, which help them to burrow underground. However, they are classified separately because they have different evolutionary histories and genetic makeup.

Marsupial moles are marsupials that are endemic to Australia, while African golden moles are placental mammals that are found in sub-Saharan Africa. They evolved independently in different parts of the world, and their similarities in physical appearance are likely the result of convergent evolution, where unrelated organisms evolve similar adaptations to similar environments.

Therefore, even though the marsupial mole and African golden mole share physical similarities, they are classified separately based on their evolutionary histories and genetic relatedness.

In recent years, the United States has experienced an increase in its consumption of natural gas.

Factors contributing to this rise include the abundance of domestic natural gas resources, advancements in extraction techniques such as hydraulic fracturing (fracking), and the transition from coal to natural gas in power generation. Natural gas is utilized for a variety of purposes, including residential and commercial heating, electricity generation, industrial processes, and as a feedstock in the petrochemical industry.

The cleaner-burning nature of natural gas compared to coal has also played a role in its increased use as the country aims to reduce greenhouse gas emissions and transition towards cleaner energy sources.

c. Prophase, 456 minutes

Explanation:

According to this question, there are a total of 60 onion cells in different stages of mitosis. Of those 60, 19 are in prophase, 14 in metaphase, 12 in anaphase, and 15 in telophase. A full cell cycle lasts for 24 hours equivalent to 1440 minutes.

To calculate the amount of time spent in each stage of the mitotic process and discover which is the longest, we divide the number of cells in each state by the total number of cells and multiply by the total time in mins.

For prophase: 19/60 × 1440

= 456 minutes

For metaphase: 14/60 × 1440

= 336 minutes

For anaphase: 12/60 × 1440

= 288 minutes

For Telophase: 15/60 × 1440

= 360 minutes

Based on the calculation above, it can be realized that PROPHASE stage has the longest duration with a length of 456 minutes.

Using the ratio principle, the longest stage is Prophase with a duration of 456 minutes

The amount of time spent in each stage of Mitosis can be calculated thus :

Time spent per stage :

Anaphase :

Prophase :

Metaphase :

Telophase :

Therefore, the stage with the longest duration is the Prophase stage and the duration is 456 minutes

Answer:

Photosynthesis

Explanation:

Oxygen is exchanged between the atmosphere and life through the processes of photosynthesis and respiration. Photosynthesis produces oxygen when carbon dioxide and water are chemically converted into glucose with the help of sunlight. Respiration is a the opposite process of photosynthesis.

Most of the oxygen gas present in the atmosphere is produced as a result of photosynthesis. Most of the photosynthesis is contributed by aquatic algae.

Photosynthesis is a process in which plants use carbon dioxide and water to prepare glucose and oxygen in the presence of sunlight. Photosynthesis is carried out by green plants that possess the chlorophyll pigment.

Oxygen makes up 21% of the atmospheric gases. Oxygen is useful for living organisms such as animals and plants. All living organisms require oxygen for various metabolic and cellular reactions. In the presence of oxygen, eukaryotic cells can produce most of the energy.

Most of the photosynthesis is carried out by aquatic plants such as phytoplankton and seaweeds. One third of the earth is covered by water. As a result, aquatic algae contribute the most to photosynthesis. As a result, most oxygen is released by them.

Hence, most of the oxygen gas present in the atmosphere is produced by photosynthesis.
