13. An insect population in an agricultural field is affected by monthly applications of a pesticide, as
shown in the graph above. A likely cause of the overall increase in the insect population over time
is
A. an increase in the population of insect predators
B. an increase in average temperature over the summer
C. an increase in soil salinity
D. a decrease in the moisture content of the soil
the survival of increasing numbers of resistant insects
E
Answer:
E. The survival of increasingly numbers of resistant insects
Explanation:
An insect population in an agricultural field is affected by monthly applications of a pesticide, and a likely cause of the overall increase in the insect population over time is the survival of increasing numbers of resistant insects. Thus, option E is correct.
What is the population?The population is a distinct group of people who share a common citizenship, identity, or set of traits. A population is a sampling that is typical of a broader group of individuals (or even objects) that share one or more characteristics.
The population is the total number of people residing in a specific place at any one time. The population should be in balance with available resources and means as one of the key aspects in maintaining a healthy ecosystem.
Therefore, option E is correct, that the survival of an increasing number of resistant insects over time is probably a contributing factor to the insect population's general growth over time.

Translate this sequence from mRNA to protein: AUG CAC UCG
Answer:
The result of the translation of the mRNA sequence AUG CAC UCG into protein is methionine, histidine and serine.
Explanation:
Messenger RNA (mRNA) is responsible for carrying the sequence of nitrogenous bases of its molecule to the ribosome to be translated into amino acids and synthesize proteins.
Three nucleotides of mRNA form triplets or codons that can encode:
The initiation of protein synthesis, with the AUG codon also coding for methionine.Amino acids to be added to the peptide chain.Stopping protein synthesis.For the mRNA base sequence AUG CAC UCG, the amino acid sequence that corresponds to the synthesized peptide or protein is Met-His-Ser, i.e. methionine, histidine and serine.
Does the existence of neurons in the body conflict with cell theory?
Answer:
no
Explanation:
Neurons are said to be the unit of the nervous system that is involved in the transmission of chemicals. No, they do not conflict with the cell theory.
What are neurons?Neurons are said to be the unit of the nervous system that acts as the messenger that uses chemical and electric signals to transfer messages from various areas. It conducts messages from the brain and spinal cord to the body parts and vice versa.
Similar to the cell theory, neuron doctrine was proposed to explain the characteristics of the nerve cells. It explained the composition of the neurons from the fundamental unit of cells that have the same analogy and genetics.
According to the cell theory, the cell is fundamental, and similarly to the nerve doctrine, the cells make the basis of the nerve cells. They also arise from pre-existing cells that duplicate in the cell division phase of the cell cycle to produce two daughter nerve cells.
Therefore, the existence of the neurons in the body does not conflict with the cell theory.

Glucose break down during cellular respiration.
O True
O False
Answer:
glycolysis; cellular respiration
During the process ofglycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy releasedduring the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate). Encyclopædia Britannica, Inc.
Answer:
True
Explanation:
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

Give reasons : a.) Diameter of afferent astride is bigger than efferent arteriole? b.) Urine is slightly thicker in summer than in winter c.) Always vasopressin is not secured? d.) Expand ESRD?
Answer:
a. Diameter of afferent astride is bigger than efferent arteriole to generate force for efficient filtration
b. Urine is slightly thicker in summer than in winter to reduce water loss from the body
c. Always vasopressin is not secreted when a person drinks sufficient water
d. ESRD stands for End stage renal disease
Explanation:
a. While transferring blood from afferent astride to efferent arteriole blood gets filtered. Filtration is efficient when the blood flows with force which is generated when blood flows from large arteriole to the small arteriole. Hence the diameter of afferent astride is bigger than efferent arteriole.
b. Urine is slightly thicker in summer than in winter to reduce water loss from the body. In summer water is lost in the form of sweat as well. Hence, urine gets concentrated to compensate for the lost body fluid.
c. Always vasopressin is not secreted when a person drinks sufficient water. The osmoregulation is maintained externally.
d. ESRD stands for End stage renal disease

Which structure is less likely to suffer severe damage during an earthquake: a high-rise, steel- frame hotel built on sediment, or a wood-frame house built on bedrock? Explain.
Answer:
The correct answer is - A wood-frame house built on bedrock.
Explanation:
An earthquake would damage a steel-frame building built on sediment in comparison of a wooden house built on the bedrock due to the fact that waves of an earthquake do not go through solid things easily such as the earth core or the bedrock land rather than reclaimed land or sediments.
So, the bedrock will shake less than the hotel or heave building built on sediment. A house that made up of wooden-frame would shake only whereas the steel-frame might damage more.

An 8-kil bowling ball is rolling in a straight line toward you, If its momentum is 16 kg m/s, how fast is it traveling?
Answer:
Velocity = 2m/s
Explanation:
Given the following data;
Mass = 8kg
Momentum = 16kgm/s
To find the speed;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
Substituting into the equation, we have;
16 = 8 * velocity
Velocity = 16/8
Velocity = 2m/s
Therefore, the bowling ball is traveling at the rate of 2 meters per seconds.

C chemistry that describes how the different materials in the atmosphere interact
D physical science that describes how water changes state in the atmosphere
Answer: B
Explanation:
weather models based on physics that describes how air moves and heat and moisture are exchanged. Hence, option B is correct.
What are weather models?Models of the weather simulate the evolution of the atmosphere through time. The result of trillions of calculations using millions of observations as initial circumstances is a three-dimensional representation of what the atmosphere might look like in the future.
All weather models operate according to the same fundamental principles, resolving numerous intricate equations at varied locations both at the surface and in various layers (heights) of the atmosphere. These equations provide solutions for a wide range of variables, including temperature, dew point, wind speed, and many others.
Weather models are based on the law of physics. Thus, option B is correct.

what is a result of nondisjunction in which an individual has three copies of a chromosome instead of two
NEED HELP FAST!!!!
Answer:
The correct answer would be - trisomy.
Explanation:
During cell division, if paired chromosomes failed to disjoin or separate from one another and therefore, pass both chromosomes to one daughter cell and none to another daughter cell. It leads to several errors in the chromosome numbers in the zygote which leads to disease or syndromes.
Trisomy or down syndrome is the condition that occurs due to nondisjunction when an individual has three copies of a chromosome in the zygote instead of two copies.
List 3 factors that can speed up the rate of chemical reactions
Answer:
TemperatureGreater Surface AreaCatalystsExplanation:
Temperature
An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).Greater Surface Area
The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. ... more particles are exposed to the other reactant. there are more collisions. the rate of reaction increases.Catalysts
A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.Hope this help!!!
