"The sun rises in the east and sets in the west" d. it is an observation which cannot be challenged.

This phenomenon occurs due to Earth's rotation on its axis. As Earth rotates from west to east, the sun appears to move across the sky from east to west, creating the illusion of the sun rising and setting. This consistent pattern has been observed and documented throughout human history, making it a reliable and well-understood aspect of nature.

While there are variations in the sun's exact path in the sky depending on the observer's location and the time of year, the fundamental principle of the sun rising in the east and setting in the west remains constant. The consistency of this natural occurrence makes it an observation that cannot be challenged, as it has been proven through countless observations and our understanding of Earth's rotation.

Plants eliminate waste products generated during photosynthesis through a process called transpiration. The primary waste product of photosynthesis is oxygen, and it is removed from the leaf through small openings called stomata.

During photosynthesis, plants absorb carbon dioxide and release oxygen as a byproduct. Oxygen molecules diffuse out of the leaf cells and accumulate in the intercellular spaces within the leaf.

From there, oxygen moves into the stomata, which are tiny pores on the surface of leaves. Stomata are open and close to regulate gas exchange and water loss. When the stomata are open, oxygen is released into the surrounding atmosphere through diffusion, effectively removing it as a waste product.

Transpiration, the process by which water vapor evaporates from the leaf's surface, also helps in the removal of waste products. As water evaporates from the leaf through the stomata, it carries away any dissolved gases, including oxygen.

This process ensures that waste products of photosynthesis are efficiently eliminated from the leaf and allows for the exchange of gases necessary for plant respiration.

Answer:

5.7 m/s     

Explanation:

The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:

1) The Physical principle: conservation of momentum.

If there is no net external force operating on a system, so the system's total momentum is conserved

The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:

P = mv.

2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.

Based on this, the calculation is as follows

Momentum before the collision:

       \(P_1 = (mass\ of\ Sheila + mass\ of\ the\ bike) \times velocity\)

       \(P_1 = (60kg + m) \times v_1\)

= 340 kg m/s

Now Momentum after the collision:

      \(P_2 = mass\ of\ sheila \times velocity\ of\ Sheila + mass\ of\ the\ bike \times velocity\ of\ the\ bike\)

\(P_2 = 60kg \times v_2 + m \times 0 = 60kg \times v_2\)

\(P_1 = P_2\)

\(= (60kg + m) \times v_1\)

\(= 60kg \times v_2\)

\(= 340 kg .\ m/s\)

\(= 60kg \times v_2\)

\(v_2 = \frac{340\ kg .\ m/s }{60\ kg}\)

= 5.7 m/s     

The velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

The given parameters;

The velocity of Sheila immediately after she is thrown from the bike is calculated as follows;

P = mv

where;

v is the velocity Sheila

\(v = \frac{P}{m} \\\\v = \frac{340}{60} \\\\v = 5.67 \ m/s\)

Thus, the velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

The DNA of telomeres has been found to be highly conserved throughout the evolution of eukaryotes reflecting that the critical function of telomeres must be maintained.

Genome protection from nucleolytic degradation, unnecessary recombination, repair, and interchromosomal fusion are provided by the specific DNA–protein structures known as telomeres. They are found at both ends of each chromosome. As a result, telomeres are crucial to the preservation of our genome's information.

With age, telomere length decreases. Somatic cells undergo senescence, apoptosis, or oncogenic transformation as a result of telomere shortening over time, which has an impact on a person's health and lifespan. Shorter telomeres have been linked to lower survival rates and an increased risk of disease. Lifestyle choices can either speed up or slow down the rate of telomere shortening.

Explanation:

The statements which is true about kinesins  is that the Kinesins move from the minus end to the plus end on microtubules.

Kinesins are microtubule-based motors localized in the mitotic spindle in order to ensure the correct segregation of the chromosomes during cellular division. These proteins are classified regarding their sequences at the core motor domains which determine their motility. Kinesins can move along microtubules in opposite directions, walking toward the plus end (i.e., the end that grows more rapidly) or moving toward the minus end.

Recently, it has been shown that opposite forces between kinesin-5 (plus-end-directed) and kinesin-14 (minus-end-directed) microtubule-based motors regulate the length of the spindle during cellular division. Kinesin-14 is a minus-end-directed motor protein that walks along microtubules from plus- to minus-end, while kinesin-5 is a plus-end-directed motor protein that walks along microtubules from minus- to plus-end, and thereby they work to shorten and lengthen the mitotic spindle, respectively.

Kinesins  are essential to all eukaryotic cells and can be found in all eukaryotic organisms. They are involved in a variety of cellular functions like the dynamics and morphogenesis of microtubules, chromosome segregation, spindle formation and elongation, and organelle transport.

Symbiotic archaea that live inside tubeworms can use two different methods to metabolize hydrogen sulfide and can switch back and forth to accommodate fast-changing environmental conditions.

Symbiotic archaea that live inside tubeworms (specifically, deep-sea tubeworms) are known as sulfur-oxidizing bacteria. These bacteria have the ability to metabolize hydrogen sulfide, which is abundant in the deep-sea hydrothermal vent environments where the tubeworms reside. Hydrogen sulfide serves as an energy source for these bacteria, allowing them to generate the necessary nutrients for their survival.

The hydrothermal vent environments are highly dynamic, with fluctuating levels of hydrogen sulfide due to the venting of volcanic gases. To adapt to these fast-changing environmental conditions, the symbiotic archaea can switch between two different methods of metabolizing hydrogen sulfide. They can either use the sulfide oxidation pathway or the sulfur oxidation pathway, depending on the availability of hydrogen sulfide and other factors in their immediate environment.

This metabolic flexibility enables the symbiotic archaea to efficiently utilize the available resources and survive in the extreme and ever-changing conditions of deep-sea hydrothermal vents.

Answer:

A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.

F. Two of A, B, C, and D are false. A is false because bacteria can be found in all four groups: heterotrophs, autotrophs, decomposers, and lithotrophic bacteria.

Autotrophs are organisms that are able to produce their own food. They use energy from sources such as the sun, chemical reactions, and inorganic compounds to synthesize organic materials, such as carbohydrates and fats, which they use for energy. Autotrophs can be found in both aquatic and terrestrial environments and have a variety of strategies for obtaining energy. These strategies include photosynthesis, chemosynthesis, and lithotrophy. Photosynthetic autotrophs use energy from sunlight to convert carbon dioxide and water into energy-rich molecules, such as glucose. Meanwhile, chemosynthetic autotrophs use energy from chemical reactions to produce organic compounds. Finally, lithotrophic autotrophs use energy from inorganic compounds, such as sulfur and iron, to synthesize organic molecules.

B is false because autotrophs can also include those that use chemical energy (such as chemosynthesis) rather than light energy.

C is true because carbon dioxide cycles between the various groups as heterotrophs produce it and autotrophs use it.
