Differentiating cells delete the dna for genes they do not need.
a. True
b. False

Answers

Answer 1
The answer is false

When the cells are differentiating in the embryo, they retain the same genetic material. However, certain genes in the differentiating cells are silenced using protein complexes called histones. This makes the genes inaccessible to RNA. Therefore, the process of transcription required in the expression of genes is restricted.

Which abiotic factor is essential to all aquatic ecosystems except ocean hydrothermal vents and why?

Answers

The abiotic factor that is essential for all aquatic ecosystem with the exception of hydro thermal vent is SUNLIGHT, THIS IS BECAUSE IT PROVIDES A SOURCE OF ENERGY. 
Sunlight is very essential for aquatic ecosystems because it is the principal source of energy from which aquatic plants trap energy to make their food and provided mean of sustenance for themselves and other organisms in the water.
Final answer:

Sunlight is the essential abiotic factor in aquatic ecosystems as it facilitates photosynthesis, except in ocean hydrothermal vents where organisms rely on chemosynthesis.

Explanation:

The abiotic factor essential to all aquatic ecosystems, except ocean hydrothermal vents, is sunlight. This factor is crucial because it influences the process of photosynthesis, which is central to the communities of organisms found in both freshwater and marine ecosystems. Sunlight affects the productivity of aquatic biomes as it controls photosynthesis, which is essential for the sustenance of primary producers in these ecosystems. In most aquatic environments, light penetration dictates the distribution of organisms, as some zones receive ample sunlight (photic zones) while others receive none (aphotic zones). However, hydrothermal vent communities rely on chemosynthesis — a process by which certain microbes convert chemicals from the vents into energy — making sunlight unnecessary for their energy production.

Which shotgun choke is best for hunting a large, slow bird, such as a turkey? cylinder (unchoked)?

Answers

The best chokes to use for large birds such as turkeys are shotgun chokes that have an extra constriction and is extended. This is because a targeted shot is needed to be made on the bird to ensure that you hit it.

Final answer:

The full choke is considered the best shotgun choke for hunting large, slow birds like turkeys. This is because it constricts the pellets to a small area, improving accuracy and extending range, which is beneficial in hitting the target's vital areas.

Explanation:

When hunting a large, slow bird like a turkey, an ideal shotgun choke would be the full choke. This type of shotgun choke constricts the pellets to a small area, extending the range and improving accuracy. Unlike the cylinder (unchoked) that spreads the pellets quickly over a wider area, a full choke keeps the spread controlled and dense, which can be beneficial for turkey hunting as it increases the odds of hitting the target's vital areas. Because turkeys are typically larger and slower birds, the extra range and precision may prove more valuable compared to a cylinder or less constriction choke. In summary, the full choke would likely be the better option for this specific hunting scenario.

Approximately what percentage of roadside litter flies out of the back of pick-up trucks

Answers

Approximately 51% of roadside litter flies out of the back of pick up trucks.
According to the Texas department of Transportation, more than half of road side litters in Texas fly out of back of pick up trucks. The habit of putting litters at the back of the truck is considered to the same as throwing the litters out of the window and efforts are been made by the government to stop this type of littering.

Final answer:

The exact percentage of roadside litter that comes from pickup trucks is unspecified, but such littering contributes significantly to environmental pollution. Improper waste disposal, such as unsecured truck loads, exacerbates the issue of waste management and urban littering.

Explanation:

The percentage of roadside litter that flies out of the back of pickup trucks is not explicitly provided in the provided reference material. However, it is important to note that littering and improper disposal of waste contribute significantly to environmental pollution. Roadside litter, including plastic bags and fast food wrappers, often originates from various sources, and unsecured loads from vehicles are indeed a contributing factor.

According to a study from the Environmental Protection Agency (EPA), over 40 million tons of food waste were generated in 2017, indicating the scope of waste management issues. Also, much of the plastic waste that ends up in the ocean comes from riverine systems, with a significant percentage coming from just a few rivers mainly in Asia and Africa. Urban areas play a key role in plastic pollution due to the concentration of human activities and improper waste disposal practices, such as the littering of plastic bags referred to as 'roadside daisies' in South Africa.

While the question about pickup trucks is specific, the overall context of the environmental impact of polluting behaviors, such as littering and unsecured cargos, ties back to the broader themes of waste management, environmental conservation, and personal responsibility.

According to thelen (1986), which reflex may contribute to the birthing process? the stepping reflex the rooting reflex the grasping reflex. the startle reflex.

Answers

According to Thelen {1986}, THE STEPPING REFLEX may contribute to the birthing process.
Stepping reflex is one of the reflexes demonstrate by new born babies. When resistance is exerted on the feet of a new born baby, the baby will respond by placing one foot in front of the other, this is called stepping reflex and Thelen suggested that this reflex may help in the birthing process.

The correct reflex that may contribute to the birthing process according to Thelen (1986) is the stepping reflex.

Thelen (1986) discussed the role of neonatal reflexes in the context of development and their potential functions. Among these reflexes, the stepping reflex is particularly interesting because it can be observed when a newborn is held upright with their feet touching a solid surface; the baby will make stepping movements. This reflex is thought to be a vestige of our evolutionary past, where it might have helped the infant to crawl and find the nipple to suckle shortly after birth.

While the stepping reflex is not directly involved in the process of birth itself, it is a reflex that emerges immediately after birth and could theoretically aid the infant in moving towards the mother's breast for feeding, which is an important aspect of the postnatal period. The other reflexes mentioned serve different purposes:

- The rooting reflex helps the baby find the nipple when the cheek is stroked.

- The grasping reflex occurs when the palm is stroked, causing the baby to grasp firmly.

- The startle reflex, also known as the Moro reflex, is a response to loud noises or the sensation of falling, where the baby throws out their arms and then pulls them back in.

Tortoises with long necks were found to be abundant in regions that had vegetation on a higher level. A few years later, drought hit the region and the vegetation dried up. Over time, grasses were observed in the region. Shortly thereafter, an increase in short-necked tortoises was observed in the region. What does this change in the species of tortoises suggest?

Answers

Answer:

A.  

Changes in the environment give rise to evolution of species.

Explanation:

I just did this on PLATO and I got 100%

Final answer:

The change in the species of tortoises suggests natural selection, where tortoises with shorter necks became more abundant in a region with grasses after a drought.

Explanation:

This change in the species of tortoises suggests natural selection at play. In the given scenario, tortoises with long necks were more abundant in regions with higher-level vegetation. This is because their longer necks allowed them to reach and access more leaves for food. However, when a drought hit the region and the vegetation dried up, grasses started to grow. As a result, short-necked tortoises had an advantage as they could easily access the grasses. Over time, these short-necked tortoises became more prevalent in the region.
