what is a sedimentary rock

Answers

Answer:

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. 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. Sedimentation is the collective name for processes that cause these particles to settle in place. Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified – turned to rock. Sedimentary rocks can be formed in deserts, lakes, rivers and seas .

A frog that is dominant for its light green color mates with a brown frog and produces one small brown frog. How is this possible if the green color is dominate?

Answers

Answer:

The dominant (light green) parent was heterozygote for the trait

Explanation:

According to Gregor Mendel in his law of dominance, an allele is said to be DOMINANT if it masks the phenotypic expression of another allele in a gene. The allele being masked is called RECESSIVE allele. In this case of a frog whose allele for light green color is dominant over the allele for brown color, the light green color allele (G) is dominant while the brown color allele (g) is recessive.

However, in a cross between that have light green frog and a brown frog, a small brown frog is produced. This is possible despite the green color being dominant because the genotype of the light green dominant parent is HETEROZYGOUS i.e. it contains both light green (dominant) allele and brown (recessive) allele.

Hence, when a gamete with recessive allele (g) is produced by the heterozygous light green frog (Gg), it mates with a recessive allele from the brown frog (gg) to produce a brown offspring (gg).

please HELP me i cant fail this class What are the two forces of gravity that contribute to tectonic plate movement at mid-ocean ridges?

Ridge subduction and slab flight


Ridge slip and slab slide


Ridge push and slab pull


Gravity does not pull them

Answers

Answer:

"Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones."

Explanation:

Does this help?

It is because of ridge slip and slab slide i the divergent plate boundaries, where tectonic plates movement creates mid ocean ridges.

What is divergent boundary?

Divergent plate boundaries are the regions where the tectonic plates are diverging from one another, this is known as a divergent plate boundary. Above upward convection currents, this happens.

The lithosphere's base is pushed upward by the rising current, which lifts it off the ground and flows lateral currents beneath it. When an oceanic lithosphere border diverges, the rising convection current beneath raises the lithosphere, creating a mid-ocean ridge.

The plate material above is dragged along in the flow direction by this lateral flow. The overlaying plate is thinned out, fractures, and pulls apart at the peak of the uplift.

Hence, in fact it is not by the gravitational pull but by the ridge slip.

When they were living, all the Glossopteris were located together on land, but now the Glossopteris fossils are separated by an ocean. What could explain how these fossils got so far apart?

Answers

Answer:

Due to splitting of lands.

Explanation:

These Glossopteris fossils got so far apart from each other because of the splitting of super continent about 175 million years ago. Before 175 million years, India and Australia are attached to each other and these Glossopteris plants are present on these lands but with the passage of time, the lands of India and Australia split and go far away from each other so due to splitting of lands, these fossils got so far apart from each other.

O Air that is unsaturated with water vapor comes into contact with the surface of the water
O Air that is cooler than the water comes into contact with the surface of the water
O Air that is warmer than water comes into contact with the surface of the water
O Air that is supersaturated with water vapor comes into contact with the surface of the water in

Answers

the answer is the first one

Evaporation occurs when air that is warmer than water comes into contact with the water's surface, hence option A is correct.

What is evaporation?

As a liquid transforms into a gas, evaporation, a sort of vaporization, occurs on the liquid's surface. For instance, a high concentration of the evaporating substance in the surrounding gas significantly slows down evaporation when humidity affects the rate of evaporation of water.

It takes in moisture from garden soil as well as the biggest lakes and seas, and the level of the water will decrease when it is heated by the sun.

Therefore, solar energy, or heat from the sun, is what causes the evaporation process to occur, hence option A is correct.

Who is to blame climate change?
Scientists have measured global temperatures for over a hundred years and see that the Earth is getting hotter. Ice core data suggests the Earth should actually be cooling if it were following its natural cycles. The trend can be best visualized by comparing each year’s average temperature with the long- term average. Figure 1 shows observations of the world’s annual average temperature made by the National Oceanic and Atmospheric Administration (NOAA). In recent decades, the years have always been hotter.
Over geologic time, the Earth’s average temperature has changed as a result of the sun’s output, the tilt and position of the Earth in its orbit, and the concentration of greenhouse gases. Scientists have developed a good understanding of the natural variations in these factors by examining different data sources in order to estimate ancient temperatures. Observations tell us that these natural factors have not been changing over the last hundred years or so in a way that would explain the observed temperature increases.
In contrast, greenhouse gases have been changing in a way that can explain the observed temperature increases. Figure 2 shows the change in atmospheric CO2 concentration over the last thousand years. At the Scripps Institute of Oceanography in Hawaii researchers have been sampling pristine mountaintop air every month since 1958. Their observations show that both the concentration and isotopic composition of CO2 is changing, and is consistent with manmade sources, including the carbon emissions from burning fossil fuels. The industrial revolution marked a drastic increase in CO2 concentrations in the atmosphere when humans began using fossil fuels on a large scale.
Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. CO2 along with other gases are known as greenhouse gases. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric CO2. In its Fifth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 95 percent probability that human activities over the past 50 years have warmed our planet.

1. What are the 2 major functions of proteins?
2. Describe the structure of proteins.

Answers

Answer:

1.  It helps repair and build your body's tissues and it also provides your body with a structural framework.

2.  Protein structure is the three-dimensional arrangement of atoms in an amino acid-chain molecule.

Explanation:

Answer:

1-Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.

2-The overall structure of the protein includes both alpha helices (green) and beta sheets (red). The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape.

Photon, light dependent reaction of photosynthesis

Explanation:

Photosynthesis is the process by which green plants make their own food in the presence of sunlight and water.

There are two steps of Photosynthesis that include light dependent reaction and light-independent reaction.

In light dependent reaction, a photon from the sun is absorbed by the green pigment in leaves called chlorophyll that allow the electron to excite from ground energy level to high energy level. It converts the solar energy into chemical energy and called light dependent reaction of photosynthesis.

Hence, the correct answer is "Photon, light dependent reaction of photosynthesis".
