Explain what TWO forces cause Earth’s water to bulge?
Answer:
Gravity and inertia act in opposition on the Earth's oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge.

why did the dialysis tubing lose water ? describe why using the terms such as hypertonic and hypotonic.
If a dialysis tubing lost water, it is likely because it was placed in a hypertonic solution, where the concentration of solutes outside the tubing was higher than inside.
What is Dialysis tubing?Dialysis tubing is a semi-permeable membrane that allows the passage of small molecules but prevents the passage of larger ones. When placed in a solution, the movement of water and other molecules across the membrane depends on the concentration of solutes on either side of the membrane.
If the concentration of solutes outside the tubing is higher than inside, the solution is hypertonic to the inside of the tubing. In this case, water will move out of the tubing through osmosis, causing the tubing to lose water and shrink.
On the other hand, if the concentration of solutes outside the tubing is lower than inside, the solution is hypotonic to the inside of the tubing. In this case, water will move into the tubing through osmosis, causing the tubing to gain water and expand.
Therefore, if the dialysis tubing lost water, it is likely because it was placed in a hypertonic solution, where the concentration of solutes outside the tubing was higher than inside. This caused water to move out of the tubing and into the solution, leading to a decrease in the volume of the tubing.

Refer to B-cells and T-cells in your answer. Discuss how and why science would need to find a way to discourage thymus atrophy if human life is ever to expand beyond around 120 years.
Answer:
1. why: to protect the organism against pathogenic infections
2. how: by using genome engineering techniques. For example, by using the CRISPR/Cas9 genome editing system in order to enlarge telomeres and thus avoid the negative effects of aging (i.e., tissue/organ atrophy).
Explanation:
The thymus plays a central role in immunity since in this organ thymus cell lymphocytes (T cells) mature into immunocompetent T-cells that initiate immune responses against pathogenic infections. Moreover, a particular type of B lymphocytes known as thymic B cells also resides at the thymus. It has been proposed that thymic B cells might be involved in the negative selection of T cells. Thus, the thymus plays a critical role in protecting the organism from infections, thereby it would be imperative to avoid thymus atrophy if human life is expanded. Nowadays, we know that telomere length shortens with age, thereby it is expected that genome engineering techniques capable of restoring telomere length might eventually avoid age effects such as, in this case, thymus atrophy. In this regard, the CRISPR-Cas 9 system is a versatile low-cost genome engineering tool that might be used for the addition of nucleotides at telomere ends.

- The seed plants makes pollen to be distributed in the environment;
- Ferns are small plants that need to be closer to water sources since they are more susceptible to dehydration.
Forested floodplain wetlands benefit from periodic flooding from rivers. When floodwaters spill into the wetland, they bring water and nutrients and leave both behind. But humans have often cut off floodplains from rivers by building roads, levees, berms, etc. Think about what would happen if a river could no longer flood into these areas. How would the resulting increased amount of water and nutrients in the river affect soils, hydrology, and life downstream?
The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.
If a river can no longer flood into forested floodplain wetlands due to human interventions, it would have significant consequences for the downstream areas in terms of soils, hydrology, and life.Without periodic flooding, the increased amount of water and nutrients in the river would not be able to disperse and be deposited in the floodplain wetlands. As a result, downstream soils would experience a decrease in nutrient inputs, leading to decreased fertility and altered composition. The absence of regular flooding would disrupt the natural hydrological cycle, reducing the recharge of groundwater and altering the flow patterns in the river system. This could result in decreased water availability, increased erosion, and changes in the overall ecosystem dynamics downstream.The disruption of nutrient flows and hydrological patterns would also have a significant impact on the life forms downstream. Aquatic plants, fish, and other organisms that depend on floodplain wetlands for breeding, feeding, and shelter would face habitat loss and reduced food availability. This, in turn, could disrupt the food chain and impact the abundance and diversity of aquatic and terrestrial species in the downstream areas.The absence of flooding from rivers into forested floodplain wetlands would lead to adverse effects on soils, hydrology, and the overall biodiversity downstream, emphasizing the importance of maintaining the natural connection between rivers and floodplains for the health and functioning of these ecosystems.For more such questions on flooding

Why do darter species that produce larger eggs have lower gene flow among their subpopulations within a stream
Answer: There is a distinction between large and small darter species.
Explanation:
The large size darters can produce small eggs and the small size darter can produce some large eggs so the large sized larvae get hatched and emerged out from the large sized eggs and they get dispersed to the short distances in the stream. Hence, the population of large and small sized darters get genetically isolated from each others as they are incompatible for mating and producing offsprings.

An organism has 18 chromosomes in its body cells. Its sex cells have 9 chromosomes.
Which statement correctly explains this?
For an organism that has 18 chromosomes in its body cells and its sex cells have 9 chromosomes, the correct statement is C, Its sex cells are haploid and a result of meiosis.
What are haploids?Haploid cells have half the number of chromosomes as diploid cells. Mitosis is a type of cell division that produces two identical daughter cells. Meiosis is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell.
In the organism described, the body cells are diploid (18 chromosomes) and the sex cells are haploid (9 chromosomes). This is because the sex cells are produced by meiosis, which is a type of cell division that reduces the number of chromosomes by half. This allows the sex cells to combine with each other to form a new diploid cell, which is the beginning of a new organism.

In humans and other mammals, X-inactivation takes place:
Question 12 options:
a) late in development, with each new cell inheriting the same inactivated X chromosome as its parent cell.
b)early in development, with each new cell inheriting the same inactivated X chromosome as its parent cell.
c) throughout the lifetime of an organism with each new cell division, both X chromosomes are activated, and one is then inactivated in each new cell.
d) early in development, with all maternal X chromosomes being inactivated and cells maintaining active copies of only the paternal X chromosome.
e) early in development, with all paternal X chromosomes being inactivated and cells maintaining active copies of only the maternal X chromosome.
The right response is d) early in development, when cells only have active copies of the paternal X chromosome and all maternal X chromosomes are inactivated.
One of the two X chromosomes is inactivated during the early stages of embryonic development, a process known as X-inactivation that affects female animals. This procedure makes sure that the proportion of X-linked genes in males and females is equal. In humans and the majority of other animals, X-inactivation starts early in development, with cells keeping only active copies of the paternal X chromosome and inactivating all maternal X chromosomes. The X-inactive specific transcript (XIST) gene, when expressed, wraps the maternal X chromosome in RNA, inactivating it. This achieves the desired result. The disruption of X-inactivation, a critical process for guaranteeing appropriate gene dosage in females, can result in illnesses and developmental problems.

Plants are autotrophic organisms, because they make their own food. Therefore, option (B) is correct.
What are autotrophic organisms?An autotrophic organism is an organism that is able to produce its own food using energy from an external source, such as sunlight or inorganic chemical reactions. Autotrophic organisms are able to sustain themselves without relying on organic matter from other sources, and they play a vital role in many ecosystems as producers.
There are two main types of autotrophic organisms: photosynthesizers and chemosynthesizers. Photosynthesizers, such as plants and algae, use sunlight as an energy source to convert carbon dioxide and water into glucose through the process of photosynthesis. Chemosynthesizers, such as certain bacteria and archaea, use inorganic chemical reactions, such as the oxidation of sulfur or methane, as an energy source to produce organic compounds.
Autotrophic organisms are important because they form the base of many food chains, providing energy and nutrients for other organisms. They also play a key role in regulating the levels of carbon dioxide and oxygen in the atmosphere.
