Answer: High temperature and drying were both associated with greater per capita mortality rate. Smaller population sizes at high temperatures and drying regimes may result from increased desiccation of adults and thus higher mortality. These precipitation effects on adult production are absent at 22°C

Other than toxic metals, temperature rise and low resource availability are factors that are also known to stress populations. A rise in temperature generally accelerates metabolic rates and hence population growth rate

Which of the following BEST summarizes the soil progression from top to bottom?
There is a decline in the amount of nutrients and a decrease in solidification.
There is an incline in the amount of nutrients and an increase in solidification.
There is an incline in the amount of nutrients and a decrease in solidification.
There is a decline in the amount of nutrients and an increase in solidification.
Answer:
There is a decline in the amount of nutrients and an increase in solidification.
Explanation:
There are many layers that constitute the formation of the soil. The layers of the soil are termed as horizons. The upper layer or the topsoil is rich in organic matter. The dead and decaying matter are constituted in the upper layer. Below each layer the level of organic material decreases. The bottom layer is the bedrock. The soil becomes hard and tough from top to bottom.
Answer:
There is a decline in the amount of nutrients and an increase in solidification.
Explanation:
The correct answer is There is a decline in the amount of nutrients and an increase in solidification. The top layers of soil are rich in nutrients but are very malleable. As the layers go deeper into the Earth, the nutrient content drops while the soil becomes harder.

Which statement best describes the Law of Superposition?
Answer:
B) In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.
Explanation:
CORRECT
The best statement for law of Superposition is in undisturbed layers of sedimentary rock, the lowest layers contain the older rocks. Thus option B is correct.
What is law of superposition?Law of superposition stated that a key stratigraphic concept indicating that within a sequence of sedimentary rock layers, the oldest layer is at the bottom and the layers are increasingly younger with ascending order in the sequence.
Superposition is defined as the ability of a quantum system to exist in numerous states until it is measured.
It can also be stated that an assumption that serves as a foundation for the sciences of geology, archaeology, and other fields concerned with geological stratigraphy.
Thus, the best statement for law of Superposition is in undisturbed layers of sedimentary rock, the lowest layers contain the older rocks. Thus option B is correct.

4. Why does sexual reproduction result in offspring with genetic variation? Use the examples that you studied to support your answer.
Answer:
Sexual reproduction results in offsrping with genetic variation due to the multiplication brings about limitless prospects of hereditary variety. The examples, that can be studied to support this would be at the end of the day, sexual generation brings about posterity that are hereditarily extraordinary. They vary from the two guardians and furthermore from one another. This happens for various reasons.
Explanation:
Sexual reproduction results in offspring with genetic variation because it involves the fusion of genetic material from two parent organisms, typically a male and a female.
What is genetic variation?Genetic variation refers to the diversity of genetic traits or characteristics within a population or species.
The process introduces genetic diversity through several mechanisms in
Independent Assortment, Crossing Over, Genetic Recombination,
Mutations.
Overall, sexual reproduction promotes genetic variation by combining genetic material from two parents through mechanisms such as independent assortment, crossing over, genetic recombination, and the introduction of new mutations.
This variation is essential for the survival and adaptation of populations to changing environments and plays a fundamental role in evolution.

If 70% of the alleles in a gene pool of a population are dominant, the frequency of the
Answer:
Explanation:
The number of copies of an allele in a population divided by the total number of all alleles for that gene in a population is the allele frequency. For a gene with two alleles whose frequencies are p and q, the Hardy-Weinberg equation states that the genotypes that are possible for the population are p^2 + 2pq + q^2, which is equal to

Humans lived with domesticated dogs over thousands of years which resulted in many breeds of dogs. Humans bred some dogs to have thick
coats to keep the dogs warm in cold climates while other dogs have thin coats that live in warm climates.
Which evidence supports the claim that dogs inherit these characteristics?
O
A. During mitosis, mutations occurred and the offspring's DNA stored this information
B. As dogs digested food, mutations occurred which changed the dog's physical appearance.
O C. Since dogs lived closely in contact with humans, the dog's genetic information remained the same.
D. During meiosis, new combinations of genetic information occurred, and the offspring's genes expressed this information.
Answer:
Did humans tame woolly mammoths or other megafauna?
Considering that some people are gifted with handling animals (e.g. horse whisperers), could paleoindians or other Pleistocene peoples have gained the confidence of woolly mammoths or mastodons to use them as transportation and other tasks, the way that Asian elephants are used today?
Fewer resources would be necessary for a human to travel long distances by riding on the back of a woolly mammoth or paleocamel, as the megafauna could graze and get energy. People may also have traveled by boat during late Pleistocene times (the kelp highway along PNW).
How could we test such a hypothesis? Cave art showing a rider on the back of one of the megafauna? A bridle and/or bit? A talisman worn by a camel is known to have been crafted from a meteorite(1), and so talismans or decorations might have adorned the hypothesized woolly steed. Metal was not a known technology during stone tool usage, as far as we know, though.

4. Describe: Compare the final histogram to the initial histogram. How have the finches been
affected by abundant rain? Describe at least two changes that you notice
Answer:
Finch with shorter beaks increase in number and population of bigger beak finches decreases.
Explanation:
Yes, finches have been greatly affected by abundant rain because in abundant rainfall plants produce an large number and variety of seeds so large amount of food is available for the finches. Due to abundant rainfall, the finches with shorter beaks increase in population. This change greatly helps finches in finding of food so shorter beak finches increase in population due to abundant rainfall.

A.
volume increases and density decreases
B.
volume decreases and density increases
C.
volume increases and density increases
D.
volume decreases and density decreases
Answer:
The answer is A, Volume increases and density decreases
Explanation:
When water is cooled from 4°C to 0°C, the volume of water increases and density decreases. Thus, the correct option is A.
What is the Density of water?The density of water may be defined as the weight of the water per unit volume, which depends on the temperature of the water. The normal density of water is 997 kg/m³.
When the temperature of liquid goes down, the density of its gradually decreases, as a result of this, the volume considerably increases.

The right answer is option a (Buckminster fullerene).
Fullerene is one of the crystalline allotrope of carbon, which was discovered in 1985 collectively by the scientists Richard E. Smalley, Robert F. Curl, Sean O' Brien, James Heath and Harold Kroto. The name 'buckminsterfullerene' was given to the fullerene molecule discovered as a homage to the American architect and scientist Buckminster Fuller.
