Here is a hypothetical situation: An area of the country has received a record amount of rainfall this year coupled with a mild winter and a warm spring and summer. As a result the mosquito population is exceptionally high. Mosquitoes are not pathogens to humans. However, mosquitoes can greatly affect the rate of infection for several types of human pathogens. Pick and describe two pathogens that you should expect to see at higher frequency because of this booming mosquito population.
Answers
Answer:
Zika virus and West Nile virus are the two pathogens which causes more diseases due to increase the population of mosquito.
Explanation:
Zika virus belongs to the family of Flaviviridae. Aedes mosquitoes which are active at day time are the carrier of this virus. West Nile virus is also spread through the bite of mosquito. The infected mosquito is the main cause of spreading of this disease. This virus is spreading too fast in the United States of America in the summer season where the population of mosquitoes increases.
Both vegetable oil and butter are made up of fats.
Why is butter a solid at room temperature, while vegetable oil is a liquid?
A)Butter is a saturated fat and vegetable oil is an unsaturated fat.
В)
Butter is a polar molecule and vegetable oil is a nonpolar molecule.
C) Butter is an unsaturated fat and vegetable oil is a saturated fat.
D) Butter is a nonpolar molecule and vegetable oil is a polar molecule.
Answers
Answer:
A
Explanation:
Butter, as good as it is, is not exactly good for us. Butter is an animal fat, or a saturated fat. This means that at room temperature these fats will remain solid. There is some science behind it and ill say this quickly, it has to do with the carbon atoms being packed with hydrogen atoms. This allows them to intertwine and be solid. The Vegetable Oil being unsaturated, a plant fat, is good for us! These are missing some of the atoms needed to make them stand up straight and be solid. So these are always liquid at room temperature! :)
We have that for the Question "Both vegetable oil and butter are made up of fats. Why is butter a solid at room temperature, while vegetable oil is a liquid?"
Answer:
Option A is the correct answer(Butter is a saturated fat and vegetable oil is an unsaturated fat)
Explanation:
Butter contains more saturated fat., vegetable oil contains more unsaturated fat.
Melting point of Saturated fat less than melting point of Unsaturated fat
Intermolecular interactions in saturated fats greater than Intermolecular interactions in Unsaturated fats
Saturated molecules are so close and forms a solid. UnSaturated molecules are not so close and forms a liquid at room temperature

Explanation: Random Fertilization means that any one sperm may fertilize any one egg as a chance event.
Random fertilization allows for a lot of diversity in offspring.
Random Fertilization means that any one sperm may fertilize any one egg as a chance event and allows for a lot of diversity in offspring. So, the correct option is (D).
What is Random Fertilization?Random fertilization refers to random mating. In this, during sexual reproduction, male gametes and female gametes which fuse to produce offspring are randomly selected from the pool of male and female gametes.
Random fertilization increases genetic diversity. When a male gamete and a female gamete finally meet which results in a large number of genetic possibilities built up during independent assortment and crossing over.
The example of Random Fertilization is when the two individuals mate, where each is capable of producing more than 8 million potential gametes, then the random probability of any one sperm and egg coming together showing 70 trillion different combinations.
Thus, Random Fertilization means that any one sperm may fertilize any one egg as a chance event and allows for a lot of diversity in offspring. So, the correct option is (D).

True or False: Cells will generally divide when they're too large
Answers
Answer:
true
Explanation:
the cell becomes two
Yes, this statement is TRUE cells will generally divide when they're too large
Why do cells divide when they get too big?The larger a cell becomes, the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane.
When cells will generally divide?The mitotic phase follows interphase. Mitosis is nuclear division during which duplicated chromosomes are segregated and distributed into daughter nuclei. Usually the cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.

Name the mandibular motion resulting from the following combinations of muscle contractions: ________
a) B Masseter, B Temporalis, B Medial Pterygoid
b) L Lateral Pterygoid, R Masseter
c) B Lateral Pterygoid, B Medial Pterygoid
d) B Lateral Pterygoid, B Digastric
Answers
Answer:
c) B Lateral Pterygoid, B Medial Pterygoid
Mandibular motion is by combinations of B Lateral Pterygoid, and B Medial Pterygoid contraction which controls the mandible's closure, hence option c is correct.
What are muscle contractions?There are several of these, including the masseter and temporalis muscles, which control the mandible's closure; the medial pterygoid muscle, which controls the mandible's closure and lateral movements.
The lateral pterygoid muscle, controls the mandible's opening, deviation to either side, and anterior movement.
The lateral pterygoid muscles on the side that is contralateral to the excursion are contracted to move the jaw to one side (laterotrusion), with the help of the posterior temporalis muscle on the same side (ipsilateral).
Therefore the combination of B Lateral Pterygoid, and B Medial Pterygoid creates mandibular motion, hence option c is correct.

Answers
Answer:
Electron transport inhibitors: Cyanide, Rotenone
Uncoupling agents: trifluorocarbonylcyanide phenylhydrazone (FCCP)(FCCP)
ATP synthase inhibitors: Oligomycin
Transport inhibitors: Bongkrekic acid
Explanation:
Electron transport inhibitors: Cyanide, Rotenone
Cytochrome oxidase also known as complex IV in the electron transport chain, carries electrons from cytochrome c to oxygen. It is a large enzyme having 13 subunits. Subunit 1 contains two heme groups , a and a3. Electrons are tranferred from heme a to oxygen bound to heme a3. The reaction of cyanide with heme a3 blocks this process of eleron transport
.Rotenone blocks electron transfer at NADH dehydrogenase (NAD−Q(NAD−Q oxidoreductase) by preventing electron transfer from Fe-S center to ubiquinone.
Uncoupling agents: trifluorocarbonylcyanide phenylhydrazone (FCCP)(FCCP)
The transfer of electrons from NADH through the respiratory chain to molecularoxygen is coupled to proton pumping from the inner mitochondrial matrix to the intermembrane space. This generates a proton motive force which is utilized in ATP synthesis. Trifluorocarbonylcyanide phenylhydrazone (FCCP)(FCCP) increases membrane proton permeability, causing protons to leak back into the mitochondrial matrix, thereby uncoupling the processs of ATP synthesis and proton flux.
ATP synthase inhibitors: Oligomycin
ATP synthase is the enzyme rensponsible for ATP synthesis. It has two functional domains,: F₁ and F₀. Oligomycin binds to F₀ and blocks the proton channel preventing rotation of the F₁ subuni, thus, preventing ATP synthesis from ADP.
Transport inhibitors: Bongkrekic acid
Adenine nucleotide translocase is a transport protein that transports free ADP from the cytoplasm into the mitochondrial matrix, while ATP produced from oxidative phosphorylation is transported from the mitochondrial matrix to the cytoplasm o the cell.
Bongkrekic acid inhibits Adenine nucleotide translocase, thus preventing ATP from leaving the mitochondria and starving cells of needed energy.

is heat involved in producing all three classes of rock.
Answers
Answer: yes. metamorphic, sedimentary, and igneous
Explanation:
Sedimentary and igneous rock is transformed into metamorphic rock inside the Earth by heat, pressure, and melting, so heat is involved in producing all three classes of rock.
What are the classes of rock?From eroding parent material, sedimentary rock is created. The source material may be sedimentary, metamorphic, or igneous in origin.
Strong heating causes hot liquid rock (magma) to break through the Earth's surface and solidify as igneous rock. This rock is worn and eroded throughout time, restarting the cycle.
The existing rock must stay solid and not melt in order to produce metamorphic rock. The rock will melt and turn into the lava if there is too much heat or pressure. An igneous rock, not a metamorphic rock, will develop as a result of this. Think about the shape changes in granite.
Therefore, sedimentary and igneous rock is transformed into metamorphic rock inside the Earth by heat, pressure, and melting.

if the ratio of the ages of kisii and esinam is 3:5 and that of Esinam and Larry is 3:5 and the sum of the ages of all three is 147 years what is the age difference between the oldest and the youngest
Answers
Answer:
The age difference between the oldest and the youngest is 48.
Explanation:
Given the following data;
The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.
The ratio of the ages of Esinam (E) and Larry (L) is 3:5.
The sum of the ages of all three is 147.
Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);
LCM of 3,5 = 15.
Hence, the ratio of the three ages is now;
K:E:L = 9:15:25
Let their ages be denoted by x;
[tex]K:E:L = 9x:15x:25x[/tex]
The sum of all three ages is;
9x + 15x + 25x = 147
49x = 147
x = 147/49
x = 3.
To find the age difference between the oldest and the youngest;
The oldest is Esinam = 25x
The youngest is Kisii = 9x
Therefore, 25x - 9x = 16x
Substituting the value of x, we have;
x = 3; 16x = 16(3) = 48.
The age difference between the oldest and the youngest is 48.
