Explanation:
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.

How do wetlands reduce flooding and erosion? (Site 1)
Answer:
by absorbing water and then releasing it slowly.
Explanation:
Answer:
Wetlands function as natural sponges that trap and slowly release surface water, rain, snowmelt, groundwater and flood waters. Trees, root mats and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain. This combined water storage and braking action lowers flood heights and reduces erosion.
Why are wetlands referred to as "biological supermarkets"? pt.2 for edn2020
Wetlands within and downstream of urban areas are particularly valuable, counteracting the greatly increased rate and volume of surface- water runoff from pavement and buildings. The holding capacity of wetlands helps control floods and prevents water logging of crops. Preserving and restoring wetlands together with other water retention can often provide the level of flood control otherwise provided by expensive dredge operations and levees. The bottomland hardwood- riparian wetlands along the Mississippi River once stored at least 60 days of floodwater. Now they store only 12 days because most have been filled or drained.

Describe the effect succession has on genetic diversity
Answer:
Dispersal fundamentally influences spatial population dynamics but little is known about dispersal variation in landscapes where spatial heterogeneity is generated predominantly by disturbance and succession. We tested the hypothesis that habitat succession following fire inhibits dispersal, leading to declines over time in genetic diversity in the early successional gecko Nephrurus stellatus.
Explanation:
Answer:
There are five main elements to ecological succession: primary succession, secondary succession, pioneer and niche species, climax communities and sub-climax communities.
Primary Succession. ...
Secondary Succession. ...
Pioneer and Niche Species. ...
Climax Communities. ...
Sub-climax Communities. while Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. Genetic diversity serves as a way for populations to adapt to changing environments.

This disease is one of the main causes of death all over the world. It the primary cause of Coronary Artery Disease (CAD). This leads to further complications, like blood pressure and heart attack. Smoking, high fat diet, physical inactivity and stress can cause this disease. Which of these cardiovascular diseases is being described?
Answer:
Hypertension, obesity
Explanation:
A coronary artery disease, CAD, can be described as a disease that affect the arteries that carries blood from the heart to other parts of the body.
In this case, the disease is known to cause the blockage of the artery which is through the deposition of excess fats in the body.

Scientists have incorporated a barley gene into a type of rice and produced rice plants that have much lower methane emissions. It is most likely that the scientists incorporated the barley gene into the rice, producing a new variety, using the process of ___________.
Answer:
The correct answer is "genetic engineering".
Explanation:
The missing options of this question are:
(1) selective breeding
(2) meiosis, followed by recombination
(3) genetic engineering
(4) sexual reproduction, followed by mitosis
The correct answer is option (3) "genetic engineering".
Genetic engineering is a modern technology that uses a DNA recombinant approach to alter the genetic material of an organism. In this case the genetic material of rice was modified by incorporating a new gene that is originated from barley. The transference of a gene from an organism to another is most easily achieved by genetic engineering technology.

Answer:
Im really confused
Explanation:
Select one of the organisms to go 'extinct' or become 'endangered' from the food web shown in the diagram. Tell how the change or loss of the organism will likely affect other organisms and the environment of the ecosystem.
Please help
Answer and Explanation:
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes the food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
When one of the links disappears, it affects the superior links as they will not have their food source. The immediately anterior link will be beneficiated, as it will not be eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link.
In the exposed example, if salmon gets extinct, the krill population will increase because they won´t be eaten by salmon. As the krill population goes up, phytoplankton will decrease, because more krill will be eating these organisms.
As salmon disappears, the cephalopod population will be affected, because salmon was one of its food sources. As cephalopods are also eaten by the puffins, these last animals will also be affected. The decrease in puffins population means that the rats' population will decrease too, as rats feed on the puffin´s eggs of puffins. Finally, foxes will be affected too, because rat´s population went down.
This is only one path affected by the extinction of the salmon. But all the animals in the trophic chain will be affected.
Answer:
Phytoplanktons.
Explanation:
This is the primary producers in this ecosystem.Its extinction will affect photosynthesis, and therefore oxygen and carbon availability for the survival of other organisms in the ecosystem.
Besides this, it is the primary producers for zooplanktons, sandlance, and krills of the food web.Therefore, its extinction affects the survival and the population of these consumers.
Consequently, Salmon, puffin, and Cepahlopods which depended on the above three primary consumers fizzled out of the foodweb.
Eventually,rats,kitiwake,,gull auklet population disappear with consequent reduction in the numbers of Fox.

Why is it necessary to convert carbohydrates into sugars? So they can be absorbed by the body Because sugars taste better than carbohydrates The body cannot get sugars from other sources Chemical energy is only found in sugars
Answer:
So that they can be absorbed by the body.
Explanation:
Carbohydrates are complex and sugars are simple form of carbohydrates. Since carbohydrates is complex and not easily absorbed it is converted to sugars which the body can absorbed easily during digestion and it is converted to energy to drive the cells. Examples of sugars are sucrose,glucose.

Why would losing just a few dozen aquatic species lead to the end of life in the ocean as we know it?
I NEED THE ANSWER BEFORE 11:59!!!!
First one gets brainiest
Answer: It would unbalance the ecosystem.
Due to the fact that if some species die off, the other species that rely on those species for food or protection would loose that food/ protection which may lead to their extinction and their extinction would lead to another extinction and so on.
There are developmental differences in the amount of gray matter in children. For example, around the ages of _____, the volume of gray matter in the caudate, a part of the basal ganglia involved in control of movement and muscle tone, peaks.
Answer:
7 in girls and age 10 in boys
Explanation:
Around the ages of 7 in girls and age 10 in boys, the volume of gray matter in the caudate, a part of the basal ganglia involved in control of movement and muscle tone, peaks. This is one of the reasons as to why girls are more athletic and flexible earlier when compared to boys who develop more muscle tone later on in life.
