Answer:
The term UV stands for Ultraviolet.
Explanation:
Ultraviolet light is a form of electromagnetic radiation which is shorter than that of visible light, but longer than X-rays. This impacts humans because it can provide harmful effects. For example, UV rays can cause premature aging of the skin and signs of sun damage such as wrinkles and leathery skin. They also cause eye problems. However, our atmosphere blocks a lot of the UV rays from the sun which is amazing because if we were every exposed to it, we would die lol
"Ultraviolet light can't be seen by the human eye but is a part of sunlight. It can be harmful to us if we are exposed to it (sunburn!) but it is mostly absorbed by the atmosphere. The presence of UV light in sunlight can be shown by using fluorescing UV-sensitive beads."

The process by which leukocytes squeeze through adjacent cells in a blood vessel
wall is called?
a) leukocytosis
b) emigration
c) cytoplasmic extending
d) positive chemotaxis
Answer:
The process by which leukocytes squeeze through adjacent cells in a blood vessel wall is called emigration
The answer is B
Leukocytes are the white blood cells responsible for protection from infections. The process by which leukocytes squeeze through adjacent cells in blood vessels is called emigration. Thus, the correct option is B.
What are leukocytes?Leukocytes are also known as white blood cells. These cells are responsible for the defense mechanism of the body. Leukocytes protect the body from infections as these are part of the body's immune system.
Leukocytes migration is essential for the ability of WBCs to react to the inflammatory stimuli at various locations within the body. These cells cannot swim due to lack of locomotory organelles. So, for the movement these cells use emigration. These process helps them to move to the site of infection to kill the pathogen and reduce the infection.
Therefore, the correct option is B.

If the temperature in an area gradually increases over time, which species would be most likely to survive?
А
species that are better adapted to warmer weather
B
species that are better adapted to colder weather
С
species that eat plants that grow in cold weather
D
species that overheat easily in warm weather
IS THIS THE RIGHT ANSWER
Answer:
Its A
Explanation:
Its the only one that benefits from warm weather.
Species that are better adapted to warmer weather would be most likely to survive if the temperature in an area gradually increases over time. Hence, option A is correct.
What is adaptation?The biological process through which organisms adapt to brand-new surroundings or alterations in their current environments is known as adaptation.
Another type of adaptation is behavioral, which modifies how an organism reacts to its surroundings. The structural adaptations made by some plants to survive in hot, dry deserts are one illustration of this. Succulent plants, which store water in their short, thick stems and leaves, have evolved to thrive in this environment.
If the temperature in an area gradually increases over time, species that are better adapted to warmer weather would be most likely to survive. Therefore, option A is correct.

Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?
Complete question:
Now you are ready for your first major assignment. Your colleagues are investigating a newly seized tusk and wonder if the tusk is from a recently discovered crime where 10 elephants from the same population were found dead with their tusks removed. The genotype of the seized tusk for five short tandem repeat (STR) loci is shown in Table 1. Allele names for each of the STR loci correspond to their size in base pairs (bp). Table 2 lists the genotypes of the same five STR loci for 10 recently slaughtered elephants.
Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?
Note: You will find the tables in the attached files
Answer:
Probably the seized tusk belonged to elephant number eight.
Explanation:
Potentially, the seized tusk might belong to individual number eight. In both the tusk and the elephant, the genetic analysis resulted in the same-sized alleles for each locus.
FH19: 193 193FH60: 147 147FH67:97 103FH71: 62 62FH129: 152 160The fact that, among the ten individuals of the population, only the individual number 8 matches the tusk for SRT loci, suggests that it belongs to the animal, but it does not ensure it 100%.

Why does carbon monoxide a triple bond instead of a double
Answer: If there was a double bond between the carbon and the oxygen, either the oxygen or carbon would only have access to six electrons, thus violating the octet rule. I think this is right but I'm not 100% sure
What is an astronomical unit?
Answer:
Astronomical unit (AU, or au), a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles).
Explanation:
The astronomical unit is a unit of length, roughly the distance from Earth to the Sun and equal to about 150 million kilometres or ~8 light minutes. The actual distance varies by about 3% as Earth orbits the Sun, from a maximum to a minimum and back again once each year.
Answer:
Explanation:
It is defined as the distance from the center of the earth to the center of the sun. Numerically that's 149.6 million kilometers

One subspecies has a large beak, which is efficient at cracking the hard seeds of the sedge, Scleria verrucosa. The other subspecies has a small beak, which is more efficient at eating the soft seeds of the sedge, Scleria goossensii. What type of selection occurred to produce this situation
Answer: Disruptive selection
Explanation:
Disruptive selection is simply referred to as an evolutionary force which brings about the division in a particular population thereby leading to a situation whereby the organisms that have an intermediate traits have a lesser reproduction than those with extreme traits who then reproduce more. Based on the question, disruptive selection will affect the regions involved.

How do enzymes reduce the amount of activation energy needed to make a chemical reaction go?
Answer:
Enzymes reduce the amount of activation energy needed by breaking substrate molecules
Explanation:
Enzymes break down substrate molecules to lower the amount of activation energy required.
What is activation energy?The least amount of energy necessary to bring atoms or molecules into a state where they may cause chemical transformation or physical transport is known as the activation energy in chemistry.
The differential of energy content between atoms or molecules in an active or transition-state configuration and the same atoms and molecules in their original configuration is known as the activation energy in transition-state theory. In mathematical formulas for values like the reaction rate constant, the activation energy is typically denoted by the symbol Ea.
Experimental rate constants or diffusion coefficients that are determined at various temperatures are used to calculate activation energies.
Therefore, Enzymes break down substrate molecules to lower the amount of activation energy required.
