In 1944, 29 reindeer were introduced onto St. Matthew Island, Alaska. The reindeer experienced exponential population growth, reaching 6000 individuals in 19 years. What would the shape of the curve be of such exponential growth?
Brought to Alaska's St. Matthew Island were reindeer.
-The population grew from 29 in the beginning to 6000 at its peak until finally crashing at 44.
-Many food sources dried up, and the heavy snowfall that year resulted in the deaths of 40000 reindeer. (Lichens are also removed)
-A little more than 50 reindeer per square mile.
Unquestionably, the reindeer's big size in 1957 was the result of their recent installation on a very favorable range, and unquestionably, the decline in body weight and skeletal size in 1963 was the effect of worse nutrition as a result of rising population pressure.The United States Coast Guard brought 29 reindeer to the island in 1944 to serve as a source of food in an emergency. A few years later, the reindeer were left on the island after the Coast Guard left. The number of reindeer then increased to almost 6,000 by 1963 before declining to 42 animals in the next two years.However, the number of reindeer, also known as caribou, in the area around the North Pole has been drastically falling recently. The size of the reindeer and caribou herds has decreased by 56 percent since the mid-1990s. That represents a loss of 2.6 million animals from an expected 4.7 million to 2.1 million.

BRO SOMEONE PLEASE HELP ! I NEED TO KNOW WHAT CELLS IN PANDAS (THE ANIMAL) MAKE THEM BLACK AND WHITE. WHAT GIVES THEM THE COLOR. MY BIO TEACHER KEPT SAYING WE SHOULD INCLUDE THAT BUT I COULDNT FIND AN ANSWER ANYWHERE! MY ALEXA WAS GIVING ME SOLAR PANEL STUFF. I WILL DO ANYTHING
Answer:
So, I don't actually know what cells do this but if you want to think about like traits, scientists believe that it stems from their poor diet of just bamboo and lack of diversity in vegetation. Also, they don't hibernate and they move through different regions throughout the year. Because of this, they have adapted to be camouflaged in those environments at once (and all year round). Studies have shown that other than camouflage, their coloration also helps with communication. It is believed that the black on their ears is a warning to predators and their eye patches are for recognition or possibly aggressive signals.
As the concentration of a solution increases, what happens to its osmotic pressure and to the tendency for water to move into it?
Answer:
Explanation: the tendency of water to move into it increases because the water in the environment will exceed in amount than the solution's. And the osmotic pressure will increase since we need more pressure to limit the inside flow of water than the 'solution before concentration increase'

What would be the advantages of using “natural regeneration” over stem cell transplants?
What problems still exist in using “natural regeneration”?
The advantages of natural regeneration is that it is very cheap and risk free, while problem with it is that it's growth is really slow.
Briefing :Advantages :
The cost of natural regeneration is less than that of stem cell transplant.Natural regeneration is risk-free and does not involve the worry about long-term, unknown effects that stem cell transplants do.The body of the patient cannot reject naturally grown cells, but it is possible for the body to reject transplanted stem cells.Problems with natural regeneration :
Economic and governmental restrictions on the regrowth of natural forests. Major global barriers to natural regeneration include harsh climates, low levels of nearby natural forest cover, and soil degradation (often brought on by intensive and long-term land use).
What are the factors affecting natural regeneration?The most important abiotic factors for the density and diversity of natural regeneration were found to be average annual rainfall, ecosystem complexity, density, species richness, and diversity (overstory).

Postharvest Losses of Fruits and Vegetables in South africa
Postharvest loss covers food lost along the entire food supply chain, from the time a crop is harvested until it is consumed.
Generally speaking, the losses can be divided into five categories:
weight loss from spoiling, quality loss, nutritional loss, seed viability loss, and commercial lossRotting, mechanical damage, poor handling, inappropriate control of temperature and relative humidity, and hygiene issues during handling are primarily what leads to post-harvest losses during retailing.What magnitude is Africa's post-harvest loss issue?
The Food and Agriculture Organization of the United Nations estimates that along the supply chain, 30% of the food produced for human use is lost or wasted annually.
This amounts to a staggering 1.3 billion metric tons of food that are never consumed.
Consumers in wealthy nations throw away nearly as much food each year (222 million tonnes) as is produced neatly in Sub-Saharan Africa (230 million tonnes).

In Labrador retrievers, a chocolate (C) coat color is dominant to black (c) coat color. A male black Labrador retriever mates with a heterozygous female Labrador retriever.
What are the genotypes of the first generation?
Cross a heterozygous individual from the first generation with another heterozygous individual.
Assuming a diallelic gene that expresses complete dominance, the genotypes from the first cross Cc x cc are 1/2 Cc and 1/2 cc. The genotypes from the second cross Cc x Cc are 1/4 CC, 1/2 Cc, and 1/4 cc.
What si complete dominance?When the dominant allele completely masks the recessive allele, we talk about complete dominance.
This is the case of heterozygous individuals that express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
When you cross an individual who is homozygous dominant with an individual who is homozygous recessive, the whole progeny among the first generation -F1- will express the dominant phenotype since they are heterozygous for this trait.
However, if you let individuals from the F1 cross with each other, the second generation -F2- will be composed of individuals expressing the dominant and the recessive phenotypes. This is because some individuals are homozygous recessive and can express the recessive trait.
We will assume this is an example of complete dominance, in which, as the statement says,

how does the structure of fatty acids relate to the way they interact with other molecules?
The structure of fatty acids relate to the way they interact with other molecules because they are hydrophobic and hence interact accordingly to several molecules.
Fatty acids are a part of the lipids. These are long chains of carbon that may be saturated or unsaturated. The saturated fatty acids are straight chains whereas kinks can be observed in the unsaturated fatty acids due to double bonds. This kink is essential to provide the fluidity to the membranes.
The fatty acids are hydrophobic because the bonds between the carbon and hydrogen are non-polar. The non-polar nature is responsible for hydrophobicity and thus the fatty acid remains away from the water molecules.

El Niño events are indicated by sea surface temperature increases of more than 0.9° Fahrenheit for at least five successive three-month seasons. The intensity of El Niño events varies from weak temperature increases (about 4–5° F) with only moderate local effects on weather and climate to very strong increases (14–18° F) associated with worldwide climatic changes.
What is the El Niño-Southern Oscillation ENSO in a nutshell?The El Niño-Southern Oscillation (ENSO) is a recurring climate pattern involving changes in the temperature of waters in the central and eastern tropical Pacific Ocean.
Whit this information we can conclude that An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.
