DNA codes for proteins by the sequence of nucleotides in the DNA. Each set of 3 nucleotides codes for a specific amino acid. Sometimes, a change in a nucleotide does NOT change the amino acid (and therefore, the protein) because some amino acids have more than one set of 3 nucleotides that code for them
what helps control heart rate and also conveys information between the spinal cord and other parts of the brain
Answer:
The cerebellum controls motor reflexes and is, therefore, involved in balance and muscle coordination. The brainstem connects and transmits signals from the brain to the spinal cord, controlling functions such as breathing, heart rate, and alertness.

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.

• 11. Thinking about trophic levels, the type of energy we use from a natural resource comes through a transfer of what, which can also be classified as radiation?
Answer: The type of energy that we use from the natural resources comes through the transfer of solar energy.
Explanation: The energy from the sun is transferred to the producers, they covert the light energy or solar energy into chemical energy.
The energy is continuously used up in the ecosystem and is also added to the ecosystem by the producers. The energy is lost in the form of heat and it reaches the earth from sun in the form of solar radiation.
The energy in the ecosystem is lost in the form of heat at various trophic levels.
The producers transfers the energy to consumers and some of the energy is lost in the form of heat.
The flow of energy(radiation from sun to producers) in an ecosystem is continuous and its loss is also continuous in the form of heat.

Are enzymes specific or not
Answer:
It's true, enzymes are specific in nature.It works on a narrow range of temperature and pH.Every enzyme has it's own activity and action.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.
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.
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.

Which muscles, when contracted unilaterally, will produce lateral bend of the spine?
Answer:
Sternocleidomastoid is the muscle which when when contracted unilaterally, will produce lateral bend of the spine
Explanation:
Sternocleidomastoid muscle is responsible for the turning of neck and its nodding. It consists of long muscles that are able to connect the three process of temporal bones i.e sternum, clavicle, and mastoid. Thus, this muscle can bend the spine laterally.

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!!!
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.

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.
