Evaluate the evolutionary benefits of regulating an internal variable, such as body temperature, versus the cost.
Answer:
The benefits of being able to regulate the internal body temperature are many and it is considered a beneficial evolutionary character, since in this way the living organism is better maintained in relation to the environment, and it achieves better balance.
Reptiles cannot control their internal temperature, it depends on the external one, that is why to warm their body they need to be in the sun, and to cool down in the shade or in temperate places.
This is a little evolutionary characteristic since the environment is very changeable and the right or ideal temperature for the organism could not be controlled.
Explanation:
Faced with climatic catastrophes or extreme situations, living organisms cannot depend on the great climatic variants, in very cold situations one enters hypothermia and in very hot conditions the proteins are systematically denatured, entering a thermal shock.

Mechanical waves react to different mediums in different ways. Some mechanical waves are _________________ through a medium, meaning they pass through the medium. The way in which waves are transmitted depends upon the type of material. In ________________, mechanical waves travel rapidly, because the molecules are ___________________ packed. In liquids and air, however, mechanical waves travel more _________________, because the molecules are spread farther apart.Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it ______________ off the medium and then travels in a ______________ direction. ______________ is an application that uses sound wave reflection to determine how deep water is. A third way mechanical waves react to a medium is _______________. When a mechanical wave is absorbed, it remains __________________ a medium and is not transmitted to another medium.
Answer:
Mechanical waves react to different mediums in different ways. Some mechanical waves are TRANSMITTED through a medium, meaning they pass through the medium.
The way in which waves are transmitted depends upon the type of material. In SOLIDS, mechanical waves travel rapidly, because the molecules are DENSELY packed. In liquids and air, however, mechanical waves travel more SLOWLY, because the molecules are spread farther apart.
Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it BOUNCES off the medium and then travels in a DIFFERENT direction. SONAR is an application that uses sound wave reflection to determine how deep water is.
A third way mechanical waves react to a medium is ABSORPTION. When a mechanical wave is absorbed, it remains WITHIN a medium and is not transmitted to another medium.
The fill in the blanks will be filled with TRANSMITTED, SOLIDS, DENSELY, SLOWLY, BOUNCES, DIFFERENT, SONAR, ABSORPTION, WITHIN

1.How does Nitrogen cycle through the enviroment?
2. Trace the steps that carbon cycles from plants,animal,and enviorment?
Answer: 1. The nitrogen cycle is a biogeochemical cycle.
2. The carbon cycle is a biogeochemical cycle.
Explanation:
1. The nitrogen cycle can be defined as the biogeochemical cycle in which the atmospheric nitrogen is utilized by the plants which is fixed by the soil bacteria. The nitrogen becomes the part of the biosphere as plants utilize it as an important development mineral. The nitrogen cycle involves the nitrogen fixation in which plants fix nitrogen by the help of bacteria into ammonia, nitrification in which the ammonia is converted into nitrite, nitrogen assimilation in which the plants assimilate and utilize the nitrogen for their growth and development, and denitrification involves the reduction of nitrite into atmospheric nitrogen. The conversion of nitrogen is carried out via physical and biological processes.
2. The carbon cycle involves the atmospheric carbon dioxide being circulated in plants as they utilize it for photosynthesis. The carbon dioxide is fixed by the plants in the form of carbohydrate which is consumed by the animals and on decomposition of plants and animals dead matter release carbon dioxide gas to the atmosphere. This allows the recycling of the carbon dioxide gas in the environment.

What is the best explanation for the difference in shape between the two drops shown below
Answer:
A
Explanation:
I think the answer is A because Hexane is a non-polar solvent and A is the only answer choice that says its non polar. Im sorry if it is incorrect
The best explanation for the difference in shape between the two drops given in image is - Option D. glycerin is polar and has greater cohesion than hexane.
Polarity is the physical characteristics of liquid that allows them to stick to other substances which is called adhesion. Polar molecules also attracted to itself, and this physical trait called cohesion. Water's most common form in the air, a droplet is formed due to this cohesion.
Hexane is a nonpolar solvent that has less electro negativity charge therefore, they do not have hydrogen bonding and there is less cohesion in the molecules.Glycerin is a polar solvent that allows its molecules to attract itself that is cohesion present and lead to more of droplet shape.Thus, the correct answer is - option D.

19. Which of the following is the best strategy to control wheat rust?
O A. Invasive insect species to attack rust
B. Fungicides to treat affected crops and planting rust-resistant varieties
C. Citrus greening to prevent the spread of rust
O D. Insulation using green roofs to limit rust
Answer:
B. Fungicides to treat affected crops and planting rust-resistant varieties
Explanation:
Leaf rust is a disease caused by the fungus Puccinia triticina which affects leaves, stems and grains in wheat and related cereals (i.e., barley and rye). This disease is known to affect crops in moist conditions. Leaf rust disease is spread through fungi spores from infected wheat plants to healthy plants. Recently, leaf rust-resistant varieties have been developed by crop improvement programs aimed at introducing leaf rust-resistant (lr) genes involved in resistance against this important crop disease. Moreover, there are different types of fungicides (e.g., Prothioconazole and Tebuconazole) used for chemical control of this disease.

Why would mutation of a tyrosine residue to glutamate in the intracellular portion of a growth factor receptor lead to increased tumor formation
Answer:
this mutation leads to a constitutively active state where the receptor can not be inactivated by dephosphorylation
Explanation:
Phosphorylation is a posttranslational modification that usually occurs at the side chains of serine, tyrosine and threonine residues, thereby regulating protein function. Phosphomimetic amino acids are substitutions (mutations) able to mimic the phosphorylated form of the protein, resulting in constitutive activation/inactivation of the corresponding protein. In this case, it is expected that the substitution of tyrosine to glutamate gives rise to a constitutively active state of the receptor by replacing tyrosine with a phosphomimetic residue.

Morphine 4mg IV push is ordered. The vial states 10mg/mL. How many mL will you give?
Answer:
If a vial of morphine has 10 mg/mL, and a dose of 4 mg is required to be administered intravenously, 04 mL must be administered to fulfill the indication.
Explanation:
Morphine is a drug, an opioid derivative, with a potent analgesic and sedative effect. Its use is intended for acute or chronic severe pain, mainly related to cardiovascular disease, cancer or severe trauma.
One vial of morphine vial has a concentration of 10 mg/mL, so if 4 mg is required, a simple calculation must be made:
Morphine: 10 mg ------------ 1 mL
Dose: 4 mg ------------ X
X = (4 x 1)/ 10
X = 4/10
X = 0.4 mL
To administer 4 mg of intravenous morphine, 0.4 mL of the injection should be used.
