1. Why can you keep getting the common cold when you can get the mumps only once?
2. What are some things you can do to improve your immune system to help fight infections?
Answer:
Once a person has developed mumps they remain immune to that disease for the rest of their lives. Therefore if they come in contact with the virus again their immune system recognises the virus and eradicates it. To improve your immune system you can eat healthy and exercise often.

How does the use of fertilizer affect the nitrogen cycle?
God bless all and stay safe! :) :)
Answer:
Nitrogen from fertilizers sinks into soils, often creating conditions that favor the growth of weeds rather than native plants. Nitrogen then washes into waterways, causing a surplus of nutrients, a situation called eutrophication.

Mosquitoes can have bigger or smaller body sizes. Two parents that have medium-sized bodies have offspring. One of their offspring has a small body, and one has a large body. How did the offspring end up with traits that are different from the traits of their parents? How did the gene combinations result in these traits?
The mosquitoes exhibit differential phenotypes because they produce distinct proteins. Different allele combinations can produce different proteins.
Phenotype can be defined as a consequence of the action of genetic factors and environmental factors that act together to shape the features of an organism.The different variants of a gene called 'alleles' encode different proteins and therefore influence the phenotype of an organism.These alleles are randomly passed from parents to offspring during fertilization, thereby generating genetically unique organisms.In conclusion, the mosquitoes exhibit differential phenotypes because they produce distinct proteins. Different allele combinations can produce different proteins.

What are the two types of anaerobic respiration? Describe the two in one paragraph.
Answer:
The two main types of anaerobic respiration are alcoholic fermentation and lactic acid fermentation.These strategies of respiration occur while the amount of oxygen available is simply too low to guide cardio respiratory.Alcoholic fermentation converts glucose into ethanol. In alcoholic fermentation, glucose is broken down via glycolysis, and two ATP molecules are released in the method. The pyruvic acid molecules produced for the duration of glycolysis destroy down into ethanol and carbon dioxide. In animals, the technique of lactic acid fermentation, further, happens after the glycolysis process. Pyruvic acid is changed into lactic acid, and muscles is damaged down through lactic acid.
Explanation:
The two types of anaerobic respiration are alcoholic fermentation and lactic acid fermentation.
Explain anaerobic respiration
Some microbes, including yeast, can ferment alcohol. This procedure transforms glucose into ethanol and carbon dioxide. Through a sequence of biochemical processes, glucose is turned into pyruvate, which is then transformed into ethanol.
On the other hand, lactic acid fermentation takes place in different types of bacteria and human muscle cells. Lactic acid is produced during lactic acid fermentation from glucose. When there is a shortage of oxygen, such during vigorous exercise when muscle cells are unable to receive enough oxygen for aerobic respiration, this process takes place. Although lactic acid fermentation results in an accumulation of lactic acid, which can contribute to muscle discomfort and tiredness, it also helps renew the NAD+ molecules required for glycolysis to proceed.

The mesoderm in an embryo will become the organism’s muscles.
Why is this statement true or false?
True; specific body parts will develop from specific cells or groups of cells in an embryo.
False; any cell in a mature embryo can develop into any cell of the body.
False; specific body parts do not develop from specific cells or groups of cells in an embryo.
True; all cells in a mature embryo can develop into muscle.
Answer:
True; all cells in a mature embryo can develop into muscle.
Explanation:
True; all cells in a mature embryo can develop into muscle. Therefore, the mesoderm in an embryo will become the organism’s muscles.
What develops from mesoderm?The middle layer of the three germ layers, the mesoderm, forms during gastrulation in the very first stages of most animals' embryonic development. The ectoderm is the outer layer while the endoderm is the inner layer. mesoderm-derived tissues.
All other body tissues, such as the dermis of the skin, the heart, the muscular system, the urogenital system, the bones, and the bone marrow, are formed from mesoderm cells, which are found between the endoderm and the ectoderm (and therefore the blood). In this process of organogenesis, which is the formation of organs, the mesoderm interacts with the endoderm and the ectoderm to give rise to the organs.

How do individuals in a population get their traits?
Answer:
New traits can also come from transfer of genes between populations, as in migration, or between species, in horizontal gene transfer. Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift.

Which statement describes Hutton and Lyell’s work?
Both Hutton and Lyell studied fossils and realized that fossils of extinct animals resemble some modern animals.
Both Hutton and Lyell claimed that Earth was very old and changed very slowly over time.
Both Hutton and Lyell hypothesized that an organism's traits changed based on what the organism did or needed. The improved trait was then passed on to its offspring.
Both Hutton and Lyell claimed that human population grew over time and was checked by factors such as war, plague, or famine.
Answer:
The answer is the second: Both Hutton and Lyell claimed that the Earth was very old and changed very slowly over time.
Explanation:
During the 19th century, the common thought was that everything in heaven and on Earth was made by God and had biblical origins. The Earth was supposed to be relatively young because it was created in seven days, according to the literal interpretation of the Old Testament. Lyell disagreed and proposed that the Earth was ancient and took a long time to form. Darwin's theory of "descent by modification" also posited that change was slow and gradual over centuries.

Answer:
1. The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (usually 21 or 22 December) and in the Southern Hemisphere, this is the June solstice (usually 20 or 21 June).
2. The Sun lies directly over 23 1/2o south. Occurring during the astrological sign of Capricorn, 23 1/2o south latitude is called the Tropic of Capricorn. Continuing to March 21st (i.e. spring equinox) the Earth has positioned itself similar to that which occurs in September, only on the other side of the Sun.
3. June 21
The latitude of 23 ½ degrees north is known as the Tropic of Cancer, and it is the northern boundary of the tropics. Question: On June 21, the subsolar point is at about 23 1/2 degrees north.
4. In 2020, the Sun will cross the celestial equator from north to south on September 22, at 13:30 UTC. Because of time zone differences, the equinox will take place on September 23, 2020 at locations that are at least 10:30 hours ahead of UTC.
5. December 21st was the Winter Solstice in the northern hemisphere. That's the day when Earth's north pole was pointed completely away from the Sun. If you lived north of the Arctic Circle, like Santa Claus, you would have experienced 24 hours of darkness. It was the day Sun never rose.
6. The farthest south that the sun's rays shine directly is latitude 23 ½ degrees south, the Tropic of Capricorn. This is the southern boundary of the tropics. On this day, the area north of the Arctic Circle gets no sunlight, and the area south of the Antarctic Circle gets 24 hours of light.
7. Tropic of Capricorn, 23 1/2 degrees S. Tropic of Cancer, 23 1/2 degrees N. Arctic Circle, 66 1/2 degrees N. Antarctic Circle, 66 1/2 degrees S. North Pole, 90 ...
8. Tropic of Capricorn: 23.5 degrees south of equator. ... at midday on December 21 is 90-36-23.5 = 30.5 degrees; on March 21
9. equator
The equator is an imaginary line drawn right around Earth's middle, like a belt. It divides Earth into the Northern Hemisphere and the Southern Hemisphere. Another imaginary line drawn straight through Earth connecting the North Pole to the South Pole is Earth's axis of rotation.
10. A day is the amount of time it takes a planet to finish one rotation on its axis. It takes Earth approximately 365 days and 6 hours to orbit the Sun. It takes Earth approximately 24 hours — 1 day — to rotate on its axis. So, our year is not an exact number of days.
Explanation:
Answer:
Antarctic Circle - 23 ½ degrees north of the South Pole
solstice - Latin root word meaning sun stands still
June 21 - summer solstice
September 23 - fall equinox
Tropic of Capricorn - 23 ½ degrees south of the equator
Arctic Circle - 23 ½ degrees south of the North Pole
March 21 - spring equinox
Tropic of Cancer - 23 ½ degrees north of the equator
equinox - Latin root word meaning equal night
December 21 - winter solstice
Explanation: At this time, the sun's closest and most direct rays strike the earth along a line 23½ degrees south of the equator. This line is called the Tropic of Capricorn. As you can see in the diagram, an area around the North Pole will not receive sunlight at all. The imaginary line of the Arctic Circle encloses this area. The Arctic Circle is only 23½ degrees south of the North Pole.
Around the South Pole lies an area which has twenty-four hours of daylight on December 21. This area is bounded by the Antarctic Circle, which is 23½ degrees north of the South Pole.
The equator is now south of the most direct rays of the sun, and the sun shines straight down on the imaginary line called the Tropic of Cancer, which lies 23½ degrees north of the equator. Summer is the season in the Northern Hemisphere, when winter is the season south of the equator. People who live in the Southern Hemisphere have their longest night of the year of this date, and those in the north have their shortest night.
(The word solstice comes from the Latin root words which mean "sun" and "to make stand still.")
(The word equinox comes from the Latin root words which mean "equal," and nox, which means "night.")
