Answer:

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation

The seven features that we can use to identify the depositional environment in which sedimentary rocks are formed are stratification, cross-beds, graded bedding, ripple marks, mud cracks, fossils, and concretions.

Sedimentary rocks are created by the materials being deposited at the Earth's surface and then being cemented at their positions by water bodies.

There are four ways that these rocks are created:

Examples of sedimentary rocks are:

They are used to making cement, glass, building stones and act as energy sources.

Females have XX sex chromosomes while males have XY sex chromosomes.

Answer:

Autotrophs

Explanation:

Autotrophs are organisms that use energy directly from the sun or from chemical bonds. Commonly called producers, they use the energy and simple inorganic compounds to produce organic molecules. Autotrophs are vital to all ecosystems because all organisms need organic molecules and only autotrophs can produce them from inorganic compounds. There are two basic types of autotrophs: photoautotrophs and chemoautotrophs.

Photoautotrophs

Photoautotrophs are autotrophs that use energy from sunlight to make organic compounds by photosynthesis. Photoautotrophs include plants, algae, and many bacteria, as shown in the figure below. They are the primary producers in the vast majority of ecosystems on Earth.

Chemoautotrophs

Chemoautotrophs use energy from chemical bonds to make organic compounds by chemosynthesis. Chemoautotrophs include certain bacteria and archaeans. They are the primary producers in ecosystems that form around hydrothermal vents and in hot springs.

Answer:

Autotrophs

Explanation:

Autotrophs are the only type of organism that produce energy for other organism.

However, there are different types of autotrophs that do 2 different things to produce their food.

First off, autotrophs are made up of fungi, algae, bacteria, and more commonly, plants.

They produce their own food two different ways,

The first way, and most commonly known, is photosythesis.

This is where a mix of carbon dioxide, water, and sunlight undergo 2 complex proccess to make glucose.

This is the energy that consumers, known as heterotrophs take from the autotrophs.

The second and less commonly known way of producing food is chemosythesis.

In chemosytrhesis, carbon dioxide or methane which is transformed into nutrients through the oxidization of things such as hydrogen gas and hydrogen sulfure, whihc are mainly found deep in the ocean in hydrothermal vents.

So, to answer your question:

Autrophs produce their own energy

Or more specific:

Plants, fungi, bacteria, and algae produce their own energy.

Answer:

The immune system is a host defence system that combines multiple mechanisms to protect an organism from several pathogens and the development of disease. The endocrine and immune system crosstalk and multiple immune processes are involved in endocrine diseases. Defects of immune tolerance associated with genetic and environmental factors result to the development of autoimmune diseases such as autoimmune thyroiditis and diabetes mellitus type 1. In addition, a mixture of immune cells and mediators is considered to be implicated in thyroid cancer development and progression. Multiple cytokines and the evolving inflammatory process are involved in the pathogenesis of insulin resistance and diabetes mellitus type 2 whereas immune mechanisms related to lymphocytes and cytokine circuits may play a role in the pathogenesis of osteoporosis. Several studies have recently been published regarding the therapeutic implications of immune system mechanisms on endocrine diseases. For complete coverage of all related areas

Answer:

I. When the temperature is 330K, the volume is 0.025 m³

II. When the volume is 0.0022 m³, the temperature is 300 K.

Explanation:

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

[tex] \frac {V}{T} = K[/tex]

[tex] \frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}[/tex]

Where;

V1 and V2 represents the initial and final volumes respectively.

T1 and T2 represents the initial and final temperatures respectively.

From the graph, we can deduce the following;

I. When the temperature is 330K, the volume is 0.025 m³

II. When the volume is 0.0022 m³, the temperature is 300 K.

Answer:

carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater. At least one-quarter of the carbon dioxide (CO2) released by burning coal, oil and gas doesn't stay in the air, but instead dissolves into the ocean. Since the beginning of the industrial era, the ocean has absorbed some 525 billion tons of CO2 from the atmosphere, presently around 22 million tons per day.

At first, scientists thought that this might be a good thing because it leaves less carbon dioxide in the air to warm the planet. But in the past decade, they’ve realized that this slowed warming has come at the cost of changing the ocean’s chemistry. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean’s pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact. In the past 200 years alone, ocean water has become 30 percent more acidic—faster than any known change in ocean chemistry in the last 50 million years.

Scientists formerly didn’t worry about this process because they always assumed that rivers carried enough dissolved chemicals from rocks to the ocean to keep the ocean’s pH stable. (Scientists call this stabilizing effect “buffering.”) But so much carbon dioxide is dissolving into the ocean so quickly that this natural buffering hasn’t been able to keep up, resulting in relatively rapidly dropping pH in surface waters. As those surface layers gradually mix into deep water, the entire ocean is affected.

Such a relatively quick change in ocean chemistry doesn’t give marine life, which evolved over millions of years in an ocean with a generally stable pH, much time to adapt. In fact, the shells of some animals are already dissolving in the more acidic seawater, and that’s just one way that acidification may affect ocean life. Overall, it's expected to have dramatic and mostly negative impacts on ocean ecosystems—although some species (especially those that live in estuaries) are finding ways to adapt to the changing conditions.

However, while the chemistry is predictable, the details of the biological impacts are not. Although scientists have been tracking ocean pH for more than 30 years, biological studies really only started in 2003, when the rapid shift caught their attention and the term "ocean acidification" was first coined. What we do know is that things are going to look different, and we can't predict in any detail how they will look. Some organisms will survive or even thrive under the more acidic conditions while others will struggle to adapt, and may even go extinct. Beyond lost biodiversity, acidification will affect fisheries and aquaculture, threatening food security for millions of people, as well as tourism and other sea-related economies.

True. The statement "In terms of plant life, this biome is extremely high in diversity, but there are very few animals that live here" accurately describes a tropical rainforest biome.

Tropical rainforest biome is known for its high level of plant biodiversity and relatively low number of animal species compared to other biomes. Tropical rainforests are home to a wide variety of plant species, including trees, shrubs, and epiphytes, but the dense vegetation and high rainfall make it difficult for many animal species to establish themselves.

However, the few species that are able to survive in the rainforest typically have specialized adaptations that allow them to thrive in this unique environment.

Answer:

A) predation is the dominant factor affecting prey population cycling

Explanation:

Predation is a type of interaction between species where one species called ‘predator’ uses another species, the ‘prey’, as a source of food. Within an ecosystem, the number of predators and prey may vary over time in cycles of time (in these cases, the population cycles of both species are closely linked). In consequence, predation is a density-dependent factor. In the case of the snowshoe hare and its predator, the lynx, when the number of predators is too high, the number of prey drastically decreases. Subsequently, this leads to the decrease of predators that leave their home range (they don’t have enough food to survive), thereby the snowshoe hare population increases again until the peak of the population cycle (carrying capacity), and so successively.

Answer:

Hello! Your answer would be, D) All of the above.

Explanation:

The energy that drives wind originates with the sun, which heats the Earth unevenly, creating warm spots and cool spots. Two simple examples of this are sea breezes and land breezes. Sea breezes occur when inland areas heat up on sunny afternoons. That warms the air, causing it to rise.
