Which process led to the release of large amounts of carbon dioxide at the end of the Devonian period?

A. The breakup of Pangaea
B. The extinction of plant life
C. The melting of glaciers
D. The volcanic activity

Answers

Answer 1

It is c my friend hope this helps

Answer 2

Answer:

Option (D)

Explanation:

The Devonian period represents the fourth period of the Paleozoic era, ranging from about 420 million years to 360 million years back. This period represents the age of fishes because a variety of fish species were present and also during this time, the plants that colonized on the land areas started undergoing evolution giving rise to the formation of gymnosperms.

By the end of this period, about 360 million years ago, massive and rapid volcanic eruptions took place, that released an extensively large amount of carbon dioxide into the atmosphere. This eventually lead to a mass extinction event, eliminating nearly 80% of the total living species present on earth.

Thus, the correct answer is option (D).

Answers

Symplastic Pathway is the route by which water is transferred from cell to cell in the root section.

Option C                                           

Explanation:

This is cellular path that takes the water from one cell to other cell using the connections which is inter cellular path relationship. These intercellular connections are called as the plasmodesmata. plasmodesmata are the membrane connections between the adjacent cells. Whenever the water molecules are crossing through the cortex and it then tends to cross the endodermis. Endodermis is the internal structure of the plant where the water molecules get diffuses freely.

a couple is about to have a baby, the father is heterozygous for eye color and the mother is homozygous recessive for eye color. what is the probability the baby will have brown eyes (B=brown b=blue)​

Answers

The answer should be 75%

According to the information, the probability of the baby that will have brown eyes is found to be 75%.

What is the reference to having brown eyes?

The reference to having brown eyes is determined by the fact that Eye color is directly related to the amount of melanin in the front layers of the iris.

People with brown eyes have a large amount of melanin in the iris, while people with blue eyes have much less of this pigment. A particular region on chromosome 15 plays a major role in eye color.

According to the context of this question, brown eyes (B) are dominant over blue eyes (b). Due to this, the genotype of the father is Bb while the genotype of the mother is bb. When they are crossed, they produce offspring with the genotypes Bb, Bb, Bb, and bb. This means that 75% of the offspring possess brown eyes.

Therefore, according to the information, the probability of the baby that will have brown eyes is found to be 75%.

Compared to the old method of clear-cutting, the impact this new strategy will have on the environment is best described as what?

Answers

Positive, since it is a sustainable plan to use a renewable resource.

The local lumber business, with this move, is doing good both, to the business itself, and to the environment. Since the amount of trees that will be cut, is immediately replaced with saplings that are taken care of, the lumber business is creating a sustainable business for the future, and also it is creating a renewable resource. The environment will also benefit from this, because the lumber business will only use certain amount of wooded area because it will have new wood constantly on the same area it is using, thus they will not have the need to spread out on a larger area and destroy the environment.

Final answer:

The new strategy's impact on the environment is less damaging and more sustainable than clear-cutting. It aims to generate economic output whilst minimising environmental damage by using methods like selective logging and efficient farming.

Explanation:

Compared to the old method of clear-cutting, the new strategy's potential impact on the environment can best be described as more sustainable and less damaging. Clear-cutting or total deforestation, historically used by early settlers in places like New England, would involve removing old growth trees entirely which results in serious environmental degradation such as habitat loss, reduced biodiversity, and soil erosion.

On the contrary, new methods aim to achieve economical output (for example, growing corn in Sherwood's forest) without excessively harming environments. These strategies might include selective logging, preserving certain habitats, and using more efficient farming methods that minimize environmental degradation. Therefore, the new strategy is less destructive and more considerate of the environment than clear-cutting.

Horseshoe crab is an example of living fossil because there are fossil extinct of ancestors of horseshoe crabs, and the species still alive today. Horseshoe crab has been around for so long; it has survived mass extinction and it is still around.  

Further Explanation

Horseshoe crab is considered living fossils because they have existed unchanged for about 445 million years. They are usually not crab; they are not closely related to lobsters or crab. Horseshoe crab is very closely related to spiders and other arachnids.

Generally, there are four species of horseshoe crab that is living today but one out of the species, called Limulus polyphemus can be found in North America. It is found near the Atlantic and gulf coast: from Maine to Mexico.

Horseshoe crab looks is almost the same with their ancient relatives despite the fact that they have been around for so long.  Their body structure is tank-like, which is made of:

5 characteristics of seaweeds

Answers

1. Seaweeds, also known as macroalgae, comprise a diverse group of organisms representing various growth forms.

2. Seaweed comes in 3 colors green, brown, and red ( but colors within these groups vary)

3.  seaweeds lack the complex reproductive structure found in sea grass and land plants

4. Most seaweed attaches to hard surfaces such as rocks, shells or other algae, using a specialized basal structure called a holdfast; however, a few seaweed species survive over mud or sandy bottoms.

5. Seaweed is autotrophic, which means it produces its own food; using sunlight, macroalgae convert carbon dioxide and water into oxygen and sugar (photosynthesis).

I hope this helps you.

Final answer:

Seaweeds are multicellular organisms that can be green, red, or brown depending on their photosynthetic pigments. They lack true tissues or organs found in land plants and instead have leaf-like blades, stalks, and structures called holdfasts for attachment. Seaweeds are capable of photosynthesis and can be found in diverse habitats.

Explanation:

Seaweeds, also known as algae, carry distinct traits that differentiate them from terrestrial plants. Here are five characteristics:

Multicellular Structure: Seaweeds are multicellular as implied in the instance of brown algae (Phaeophyta).Colouration: Their color can be either green, red, or brown, determined by their photosynthetic pigments.Lack of True Tissues or Organs: Unlike land plants, seaweeds do not have true tissues or organs such as leaves, stems, or roots. They have leaf-like blades, stalks, and structures called holdfasts for attachment.Photosynthetic: Seaweeds have multiple photosynthetic pigments (chlorophyll a, chlorophyll c, B-carotene, and fucoxanthine), which enable them to perform photosynthesis.Diverse Habitat: Seaweeds thrive in a variety of habitats including seawater, brackish water, and even snow patches.

How is a class system different from a caste system?

Answers

Answer:

A class system is a more smooth system, caste is more of a system that changes consistently.

Explanation:

"Class system is typically more fluid than the caste system or the other types of stratification and the boundaries between classes are never clear-cut. Caste system is static whereas the class system is dynamic. ... In the caste system, individual mobility from one caste to another is impossible."

Final answer:

A class system is somewhat open and allows for social mobility based on individual accomplishments and social factors, while a caste system is a closed system where social standing is determined by birth and allows for little to no change in social position.

Explanation:

A class system is a way of stratifying society where people's positions are based on both social factors and individual accomplishments. This system is somewhat open and allows for vertical movement or social mobility based on factors like wealth, income, education, and occupation. A person in a class system, unlike in a caste system, can improve their position through personal choices and opportunities.

On the other hand, a caste system is a closed stratification system where social standing is determined by ascribed status or birth, meaning it allows little to no change in social position. This system regulates all aspects of an individual's life including occupations, housing, and even marriage partners. This system is entrenched in society, and individual interests and capabilities don't provide opportunities for improving their social standing.

The Hindu caste system in India, for example, is heavily based on religious beliefs about karma and reincarnation. Although caste-based discrimination is now illegal in India, the system is still deeply embedded, especially in rural areas. Today, India's cities and corporations offer more opportunities for career choices and merit-based hiring, gradually shifting societal expectations tied to the caste system.

Answer:

Boxwood shrubs are slow-growing plants with dark green glossy leaves. Some varieties have variegated leaves. Leaf shape depends on the variety; some are round while others are elliptical. They provide thick cover because the foliage begins close to the ground and is dense enough to block light.

Explanation:

English boxwoods are adaptive shrubs with ornamental features that can tolerate drought and poor soil. They have shallow root systems but can be vulnerable to diseases affecting the top of the shrub, requiring pruning of dead branches and sometimes removal if diseased. Other resilient ornamental shrubs can be used as replacements.

Boxwood shrubs can be found in a range of sizes and have a variety of adaptive features to survive in different environments. For example, they possess shallow, extensive root systems which allow them to thrive even in drought and poor soil conditions.

Problems with English boxwood can arise, often with severe damage to the top of the shrub appearing in the spring. It's recommended to prune out dead branches but to wait until June to confirm that the branches are indeed dead. In cases where disease is suspected, affected branches should be pruned out and samples should be submitted for laboratory analysis. Unfortunately, there are currently no effective disease management tactics, so removal of diseased boxwood may be necessary.

What are some Differences from bean roots?

Answers

Final answer:

Radish plants do not form nodules like bean roots. Although there are some similarities between radish and bean roots, there are also differences such as the size, thickness, and color of the roots.

Explanation:

Radish plants do not form nodules like bean roots do. Nodules are found on the roots of legume plants, such as beans and peas, and contain bacteria called Rhizobia that help fix atmospheric nitrogen into a usable form for the plant. Radishes, on the other hand, do not have this symbiotic relationship with nitrogen-fixing bacteria.

Despite the differences in nodules, there are some similarities between radish and bean roots. Both radish and bean roots have a primary root that grows vertically downward and numerous lateral roots that branch out horizontally. They also both have root hairs, which increase surface area for absorption of water and minerals from the soil.

However, there are also differences between radish and bean roots. For example, radish roots are typically shorter and thicker than bean roots. Radish roots also tend to be less fibrous compared to bean roots, which can be quite long and stringy. Additionally, radish roots are typically white or pink in color, while bean roots can range from white to brown.
