Answer:
Muscles under the skin make body hair stand on end.
Explanation:
The body needs to keep its temperature around a set point of about 37 degrees Celsius.
Muscles under the skin make body hair stand on end happens during the thermoregulation.
What do you mean by thermoregulation?Thermoregulation is a mechanism by which mammals maintain body temperature with tightly controlled self-regulation independent of external temperatures. Temperature regulation is a type of homeostasis and a means of preserving a stable internal temperature in order to survive.
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different.
Thermoregulation is controlled by the hypothalamus, which is a small structure in your brain. If the hypothalamus senses your body's temperature is too high or low, it sends signals to your nervous system.

Answer:
Trait.
Explanation:
Trait can be defined as a distinguishing quality or characteristic of a living thing.
Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.
Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
For example, John is so tall and has a curly hair, it's obvious he acquired the trait from his mum.

If you are examining rock layers that are suspected to be about 20 million years old, which radioactive isotope would you use? Explain your answer
Answer:
Scientists usually use the potassium-argon method to date rocks that are older than about 1 million years. Uranium-238 is also used for radiometric dating.
The radioactive isotope most applicable to date rocks of about 20 million years is Uranium
The use of radioactive isotope is used in the radiometric process of dating materials. Dating techniques are used in other to determine the age of rocks and minerals.
In other to ensure the effectiveness of the radiometric process, it is essential that the half life of the isotope be determined in other to measure the age of the rock. For instance, carbon - 14 isotope has an half life of 5,730 years. Hence, carbon - 14 dating will only be used in dating rocks below 50,000 years.In other to examine Rock layers of about 20 million years, the radioactive isotope to be used will be Uranium which could be used to date rocks of about hundred _ thousand million of years.

Water clarity, or turbidity, measures the amount of sediment and debris in a body of water. Since light cannot shine into water with low clarity, turbidity is a factor that is considered when monitoring water quality. Which of the following organisms would be most negatively affected by unclear water?
A. plants growing on the lake floor
B. trout feeding near the lake surface
C. trees growing along the lake shore
D. geese nesting on the bank of the lake
Answer:
plants growing on the lake floor
Explanation:
Have a nice day!
The organisms that would be most negatively affected by unclear water are plants growing on the lake floor. The correct option is A.
What is water clarity?Water clarity is a measure of how far down the water column light can penetrate. Clear water has low concentrations of suspended soil particles and/or algae.
Water clarity has huge consequences for the diversity and productivity of aquatic life that a system can support because it is closely related to light penetration. Clearer water, for example, allows more sunlight to reach submerged aquatic vegetation.
Water clarity is critical for a variety of reasons. It influences the depth to which aquatic plants can grow, the amount of dissolved oxygen in the water, and the temperature of the water. Fish, loons, and other wildlife rely on clear water to find food.
Thus, the correct option is A.

While carrying out a hanging drop experiment, one of the researchers forgot to add grease to the multi well plate. How will this affect the crystalization process?
Answer and Explanation: The role of oil/grease in the hanging drop experiment can not be over emphasised especially for small volume trials.
The macromolecule solution to be crystalized is mixed with a precipitating agent on a glass plate. This is then inverted over greased wells creating an overhang.
Greasing the wells ensures a proper seal as it acts as an inert sealant that prevents the evaporation of the solution, but also can easily contaminate the macromolecule solution to be crystalized. Grease also affects the crystallization process throughout its stages of nucleation and growth, and also enhances the stability of the emerging crystals.
An organism has the genotype "Aa" for a particular trait. As a result of segregation during meiosis, what alleles will each gamete contain? Group of answer choices
Answer:
one "A" or one "a"
Explanation:
In diploid species (2n), each individual inherits two gene variants (alleles) for each gene, one from the father and one from the mother. This means that each haploid gamete (n) receives one copy of each homologous chromosome that contains only one form of that gene (i.e., one allele). In consequence, and according to Mendel's First Law, alleles segregate into separate gametes (in this case either "A" allele or "a" allele since the parental genotype is heterozygous for this gene).

What is the Gila Monster’s advantage/disadvantage?
The Gila monster is one of only a handful of venomous lizards in the world. Others include the similar-looking Mexican beaded lizards, as well as iguanas and monitor lizards. Its venom is a fairly mild neurotoxin. And though a Gila bite is extremely painful, none has resulted in a reported human death.
It has been accused of many things, such as spitting venom, leaping several feet in the air to attack, stinging with its tongue, and killing people with gusts of poisonous breath. ... It may even chew so that the venom goes deeper into the wound. A Gila monster bite is painful to humans, but it rarely causes death.
Powerful muscles control the jaws and give the Gila Monster a bite like a bulldog--it just won't let go. This gives the venom a chance to work, weakening or disabling the lizard's prey.
