Answer: This means that the further away the galaxies are, the faster they are moving. ... Red-shift data provides evidence that the Universe, including space itself, is expanding. Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. ... When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer.

F. release of fresh water into ocean water as icebergs melt
G. decomposition of organic matter at the bottom of oceans
H. release of large amounts of salt from icebergs into the ocean
Answer:
f
Explanation:
Evaporation of water from oceans at the equator is an example of an interaction between the cryosphere and hydrosphere. So, the correct option is (E).
What are Hydrosphere and Cryosphere?The cryosphere is define as the part of Earth's climate system which includes solid precipitation, snow, sea ice, lake and river ice, icebergs, glaciers and ice caps, ice sheets, ice shelves, and seasonally frozen ground. The word is derived from the Greek word 'kryos' which means frost or icy cold.
The hydrosphere is defined as the sum of the Earth's water such as seas, land, surface, and air. About 71 percent of the Earth's surface is covered by water where only three percent is fresh water. Even less can be used as drinking water. They both interact at equator in the form of Evaporation.
Thus, Evaporation of water from oceans at the equator is an example of an interaction between the cryosphere and hydrosphere. So, the correct option is (E).

Question 1 After evaluating your MyPlate recommendations, make a prediction. Do you think your diet will meet these daily recommendations? Are there any recommendations you don't think your diet will meet?
Answer and Explanation:
I don't think MyPlate's recommendations will meet my daily recommendations because those recommendations are focusing too much on the amount of carbohydrates and are not meeting the need for other types of elements, such as healthy fats, for example. In that case, an extremely high carbohydrate diet will get me into trouble and make my body need it. Ideally, I should look for recommendations from a nutritionist who can, in fact, help me establish a healthy and complete diet.

How do introduced species become established in a new ecosystem
explain how the population of octopuses and seaweed in this ecosystem might be affected if a disease reduced the crab population
Answer:
Seaweed might start to grow out of control withough crabs eating it, octopuses on the other hand would struggle to find food and start to die off because they relie on crabs to be their food source.
Without crabs to consume it, seaweed would start to grow out of control; octopuses, on the other hand, might struggle to find food and begin to disappear because they depend on crabs as a food supply.
What is the role of seaweed and octopus in ecosystem?
Seaweeds are important components of marine ecosystems. They serve as the primary source of nutrients and energy for marine organisms.
Either directly when fronds are consumed or indirectly when decomposing sections break down into small particles that are ingested by filter-feeding species.
No other creature has a predatory function as significant as that played by octopuses in forming communities.
Therefore, the population of octopuses and seaweed in this ecosystem might be affected if a disease reduced the crab population.

If an air mass is sinking, it must be
A. cold and less dense
B. warm and more dense
C. cold and more dense
D. warm and less dense
Answer:
The awnser to your question is C.
Explanation:
The colder matter is the atoms get closer therefore making the matter more dense. A. is half correct but if the matter is cold it wouldn't be more dense because when something is less dense it goes above whatever is around it. Take for example water and oil. They seperate into different layers due to density. Hope this helps. :)
The airmass is a large homogenous mass of air over a region that could be for many days.
The volume of air is defined by the temperature and water vapor content. Airmass may spread from hundreds to miles and are classified according to latitude and altitude. There are 4 types of air mass artic, tropical equatorial, and polar. The airmass that is light is warm and has a low pressure always lifts upwards. The cold and cool airmass always settles as it's dense and heavy. Hence the option C is correct.Learn more about the air mass is sinking, it must be.

Imagine that the cell is exposed to some kind of stressor such as extremes of temperature, exposure to toxins, or mechanical damage. The chain reactions will be
Disruption or the formation of cell membrane blebsAlteration of protein synthesis and accumulation of altered proteins in the ERAlteration of the chromatin of the chromosomes inside the nucleus and DNA damageAlteration of the permeability of organelles such as mitochondria with consequent alterations in metabolismDecrease in ATP levels and increase in cytoplasmic calcium levelThe combination of all this can lead the cell to death but it can respond in various ways:
the cell can decrease protein synthesis and induce the transcription of specific stress-sensitive chromosomal genes that correct altered proteinsIt can respond to DNA damage by stopping replication and trying to repair it If it cannot survive it can commit suifcide so as not to harm other cellsWhen a sperm and egg combine, it is called _______________________________

In cattle, a single gene with two alleles determines fur color. The fur can be red, white, or roan. Roan fur has both red and white hair. Which of the following is true about alleles for fur color in cattle?
The allele for roan fur color is dominant over red and white fur color.
The allele for red fur color is dominant over white and roan fur color.
The roan and white alleles are expressed independently of the other.
The red and white alleles are expressed independently of the other.
Answer:
D
Explanation:
D the red and white alleles are expressed independently of each other. You know this because roan is when both red and white are present. So therefore, because of this, the cow can be red, white, or both depending on what alleles are present.
What are some freshwater systems and what do they all share in common?
Answer:
There are three main types of freshwater biomes: ponds and lakes, streams and rivers, and wetlands. We'll go into the details of each below. Ponds and lakes are often called lentic ecosystems. This means that they have still or standing waters, not moving like rivers or streams.
Explanation:
Water is broadly classified as fresh and salt water. Examples of fresh water systems I know are;
Ponds, rivers, lakes, and reservoirs.Similarities among all these sources of water are the fact that;
They are all small bodies and have a low amount of salt. They are also shallow and not dense.Fresh water makes up about 1 percent of the world's surface area whereas salt water which is found in large bodies of water takes more than 95% of the earth's surface area.
Smaller bodies of water are mainly freshwater. These are shallow, have low salt content, and are not quite dense. Large bodies like oceans and seas are known to have high salt content.

In guinea pigs, short fur (S) is dominant to long fur (s). Two heterozygous guinea pigs
(Ss) mate. Complete the Punnett square and then list the percentages of the
expected genotypes for their offspring.
Explanation:
A way I like to remember heterozygous is by remembering that the other word for heterozygous because brainly wont let me say it apparently. The same gender liking each other, so (word) is same, hetero is different.
each square would have 25% each because 100%÷4=25.
Dominant one is like mixing black and blue together,the black is gonna give a dark effect to blue so black is dominant.
Blue is recessive.
The percentage of the Ss is 75% while the percentage of the ss is only 25%.
Performing a crossGiven that we have the genotypes of the both parents as Ss. The Ss imples that the gene for short fur is dominant over the gene for long fur.
Now, when we perform te cross for the first generation, we will discover that we have the offspring; Ss, Ss, Ss and ss. The percentage of the Ss is 75% while the percentage of the ss is only 25%.

In patients infected with nonresistant strains of the tuberculosis bacterium, antibiotics can relieve symptoms in a few weeks. However, it takes much longer to halt the infection, and patients may discontinue treatment while bacteria are still present. How could this result in the evolution of drug-resistant pathogens?
The bacteria are still present and may obtain antibiotic resistance to spread to other species by horizontal gene transfer.
Antibiotics have become diluted and weak because of a limited supply.
Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.
Resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.
