What advantages do flowers give angiosperms over gymnosperms?

Answers

Hey! Look what I found online.

In general, it makes the angiosperms more efficient in pollination and, therefore, in producing seeds. Most angiosperms have perfect or bisexual flowers, that is, both the male and female reproductive organs are borne on the same flower while these are separated in the gymnosperms. In the conifers which are gymnosperms, thousands of pollen grains will be needed to pollinate one female. The pollens are carried by the wind and having one pollen land exactly on the stamen is quite an impossibility. 

Many angiosperms have colorful petals. This attracts the insects and birds. As they move from one flower to another, they deposit the pollens on the stigma of another flower. The nectar that angiospermous flowers produce and the aroma emitted play the same role.


Based on water temperatures, currents, and the potential kelp forest locations, identify one location where upwelling is most likely to take place. Explain your reasoning

Answers

It is said that upwelling happens in the open oceans and along coastlines. Upwelling is a process wherein winds blowing across the ocean surface push the water away and the water beneath the surface goes up to replace the pushed water. 

The water that upwells is colder in temperature and has richer nutrient content which results to a high biological productivity of the surface waters.  

Kelp forests are abundant in areas where upwelling occurs. 

The most likely location for upwelling would be a coastal area with the right combination of wind patterns, ocean currents, bathymetry, and the presence of kelp forests, all of which point to the presence of nutrient-rich, cold water being upwelled to the surface.

Upwelling typically occurs at the coast where wind-driven currents move away from the land, allowing deeper, colder, and nutrient-rich water to rise up and replace the surface water. This phenomenon is common in areas with persistent winds that blow parallel to the coastline in a direction that causes the surface water to move offshore due to the Coriolis effect. The Coriolis effect is a force that acts on objects moving in a rotating system, such as the Earth, and it causes the water to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Kelp forests are often found in these areas because they thrive on the abundant nutrients brought to the surface by upwelling. The ideal location for upwelling would therefore be a coastal region with:

1. Persistent winds that blow parallel to the coastline and in the correct direction to push surface water offshore.

2. A steep continental shelf that allows deep water to be brought up closer to the surface.

3. Cooler sea surface temperatures, which can indicate the presence of upwelled water.

4. The presence of kelp forests, which are indicators of nutrient-rich waters.

By analysing these factors, one can determine the most likely location for upwelling. For example, if the potential kelp forest locations are found along a western coast of a continent in the Northern Hemisphere, and there is evidence of cooler sea surface temperatures and persistent northward winds, then this area would be a prime candidate for upwelling. The cold, nutrient-rich water rising to the surface would support the growth of kelp forests, and the presence of these forests would in turn help maintain the upwelling conditions by providing a physical structure that can dampen wave energy and reduce the mixing of the water column, allowing for more efficient nutrient utilization by the kelp.

Explain how a GIS can model the relationship between a natural resource and an observed change. Include an example of a change in the availability of a specific natural resource and a specific observation of nature.

Answers

Answer:

Water in a river can be traced through GIS

Explanation:

With the improvement in observational tool, GIS technique has proved exceptionally helpful in tracing the natural resources. The pixels number and color help us to trace the changes in quantity as well as quality.

For example -

Suppose,  a river and its channel is being traced through GIS.

In year 1991, the number of pixels covering a certain area and of sky blue color signifies large volume , area of water and its good quality respectively

However, after 10 years  image of same are may show a change in previous observation such as reduction in number of blue pixels and also change in color from blue to red signifying increase in pollution level.

GIS can be used in analyzing the data that are related to the place where a natural resource is gotten.

A geographic information system is important as it helps in the capturing, storage, and display of the data that are related to a particular position on the surface of the Earth.

When natural resources are found in an area, the geographic information system can be used in getting further information about the area. A geographic information system can also be used in the management of natural resources as they give spatial data which are necessary to know the disasters that have taken place in such an area before.

In conclusion, GIS is beneficial in natural resource management.

Because it controls the pituitary gland, the brain's _____ ultimately controls the endocrine system.

Answers

Because it ........................., the brain's HYPOTHALAMUS ultimately controls the endocrine system.
The hypothalamus is the part of the brain that controls the endocrine system, it does this by linking up the nervous and the endocrine system via the pituitary gland. Hypothalamus functions by releasing hormones which either inhibit or stimulate production of hormones in the anterior pituitray gland.

The brain's hypothalamus controls the endocrine system by regulating the pituitary gland, which is the master gland responsible for the secretion of hormones that affect other glands and bodily functions.

Because it controls the pituitary gland, the brain's hypothalamus ultimately controls the endocrine system. The hypothalamus is a critical part of the brain that provides a link between the nervous and endocrine systems by controlling the pituitary gland, also known as the "master gland".

This master gland secretes various hormones that influence other endocrine glands such as the thyroid gland and pancreas, which are responsible for essential physiological processes like growth, metabolism, sexual maturation, reproduction, body temperature, and blood pressure regulation. The pituitary gland produces several hormones, including growth hormone, endorphins for pain relief, and hormones that regulate fluid levels in the body, exemplifying its central role in the body's hormonal regulation.

The liver converts alcohol to __________, which in high levels causes permanent liver damage.

Answers

Carbon dioxide and water

The liver converts alcohol to acetaldehyde, a toxic substance that can cause a variety of liver diseases and potentially lead to permanent liver damage, particularly with heavy and chronic alcohol consumption.

The liver converts alcohol to acetaldehyde, which in high levels causes permanent liver damage. When alcohol is processed by the enzyme alcohol dehydrogenase (ADH), it is transformed into acetaldehyde, a toxic intermediate. With chronic heavy consumption of alcohol, this substance accumulates and can lead to a range of liver diseases, including fatty liver, inflammation (steatohepatitis), fibrosis, cirrhosis, and an increased risk of liver cancer. The liver's ability to function is significantly impaired as acetaldehyde contributes to the formation of fatty liver and can ultimately lead to cirrhosis, a severe liver damage where liver cells are replaced by scar tissue.

In addition to liver damage, acetaldehyde toxicity is associated with the development of other health problems, including pancreatic damage, increased blood pressure, heart diseases, stroke, and various forms of cancer. These health risks highlight the reasons why controlling alcohol intake is crucial to maintain overall well-being and prevent long-term damage to vital organs.

Answers

Observations..

Gokd luck ;)

Answer:

B. testing explanations

Explanation:

Aristotle defines science as "knowledge of causes by causes. It is demonstrative knowledge".

Science consists of three components: observation, experimentation and laws. It aims at the union between theoretical knowledge, practice and technique. It does not use assumptions, but verification after applying the scientific method.

In short, science is the knowledge that explains phenomena according to laws that have been verified by experimental methods. Accordingly, we can say that what differs science from other subjects such as arts and history is that science depends on testing explanations.

The process in which one species evolves into a variety of species is called apes

Answers

Final answer:

The process in which one species evolves into a variety of species is called adaptive radiation or divergent evolution. It involves speciation through branching events and common ancestry.

Explanation:

The process in which one species evolves into a variety of species is called adaptive radiation. It is a mechanism for speciation that occurs when a single species evolves into many new species to fill available niches. This process results in enormous variation in form and function, and is seen in various organisms including flowering plants and hominids.

Divergent evolution is another term used to describe when two species evolve in different directions from a common point. This can be observed in reproductive organs of flowering plants or in the evolution of different hominid species.

A crucial aspect of this process is the concept of common ancestry, which means that related species share a common ancestor. This principle is illustrated in Darwin's concept of branching evolution, where one species branches to form more than one new species over time.

Adaptive radiation is the process where one species evolves into multiple new species, each adapted to different environments or niches. It is a significant part of evolution, exemplified by Darwin's finches.

Adaptive Radiation in Evolution

The process in which one species evolves into a variety of species is called adaptive radiation. This occurs when a single ancestral species diversifies into multiple new forms, each adapted to a distinct niche or environment. This process is a significant aspect of evolution, the gradual change during which new species arise from older species and some species become extinct.For example, the finches on the Galápagos Islands, studied by Charles Darwin, are a classic example of adaptive radiation. These finches evolved from a common ancestor into various species with different beak shapes and sizes, each adapted to different food sources. This diversification helps species survive in different environments and reduces direct competition for resources.

Answer:

7.

Explanation:

pH may be defined as the negative logarithms of hydrogen ion concentration. The pH scale is used to determine the acidity and the basicity of the proteins on the pH scale.

Acids has the pH less than 7 whereas the base has the pH more than 7. Since, the cell contains large amount of water, its pH is 7. Water is a neutral molecule and neutral substances has pH nearly equal to 7 when measured on the pH scale.
