Acceleration of a body is defined as rate of chance in velocity with respect to time and its S.I. Units are / or
Magnitude of average acceleration of a body = (final speed - initial speed)/time interval =
where, final speed =v= 11 m/s; initial speed = u = 6 m/s; and time interval = t = 3 s
Hence acceleration = =
=
Answer:
The acceleration of the object is 1.667 m/s2.
Explanation:
Given data:
Initial velocity = v1 = 6 m/s
Final velocity = v2 = 11 m/s
Time period = t = 3 s
Solution:
Acceleration = a = ( v2 - v1)/t
By putting values in the above formula:
Acceleration = a = (11 - 6)/3
a = 5/3 = 1.6667
Explanation:
Acceleration of an moving object is the change of velocity of an object divided by the total time taken by the object which is time period. So by putting values it comes that acceleration of object is 1.6667 m/s2.
The unit is meter per second square.

Answer:
In sample A,
The percentage of thymine or T is 20.5 %. A = T, so the percentage of A will also be 20.5 %.
Thus, A + T = 20.5 + 20.5 = 41 %
Therefore, G + C = 100 - 41 = 59 %
So, G = 59 /2 = 29.5 %
Also. G = C = 29.5 %
In sample B,
The percentage of Thymine or T is 30.7 %. As A = T, so A will also be 30.7 %.
Thus, A + T = 30.7 + 30.7 = 61.4 %
Also, G + C = 100 - 61.4 = 38.6 %
So, G = 38.6 / 2 = 19.3 %
Therefore, C will also be 19.3 %. As GC content is more found in the sample A, that is, 59 %. Hence, the sample A will possess the higher temperature to denature in comparison to B.

Answer:
No, since different genes will exert varying degrees of influence on the trait
Explanation:
The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.
Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.
Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotypeand genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.
Let us see, for instance, the eye color trait, which results from the interaction of many genes. Two of them significantly contribute to the color green, blue, or brown, while the rest of the involved genes play a role in defining the spectrum of phenotypes of each eye color. So, there are different tones of blue eyes, green eyes, and brown eyes, and the differences are determined by the contribution of each allele to the phenotype.
Final answer:
In polygenic inheritance, multiple genes influence a trait, and theycan have varying degrees of influence rather than having the exact same effect.
Explanation:
In polygenic inheritance, it is not accurate to say that all genes controlling a trait will have exactly the same influence over the trait. Polygenic inheritance involves multiple genes that work together to influence a trait. This means that these genes do not necessarily exert the same degree of influence; rather, they can and often do exert varying degrees of influence on the expression of a trait. For example, in human skin color, a characteristic feature of polygenic inheritance, several genes, each with different levels of influence, contribute to the trait's expression.

The mass extinction that led to the loss of 96% of marine life and 70% of terrestrial life was most likely due to a supernova, an asteroid impact or Volcanic Eruption.
What is Mass extinction?
An extinction event is defined as a widespread and rapid decrease in biodiversity on Earth. Those events are characterized by sharp changes in the diversity and abundance of multicellular organisms that occur when extinction rates increase relative to background extinction rates and species evolution rates.
This mass extinction which happened during the end of the Permian era. The extinction of 96 percent of all marine species and 70 percent of all terrestrial species resulted in catastrophic changes on Earth, which became almost devoid of all species.
The cause of this mass extinction is related to volcanic activity, supernova or asteroid impact which could have increased the average temperature of the Earth's surface.
Thus, the mass extinction that led to the loss of 96% of marine life and 70% of terrestrial life was most likely due to a supernova, an asteroid impact or Volcanic Eruption.

Answer:
(a) Fluid intelligence
Explanation:
Intelligence is the ability of an organism to adapt to it's environment through learning and shaping it's environment. It does so with the help of it's cognitive abilities.
The persons ability to do this speedily and abstractly is known as Fluid Intelligence.
Final answer:
Fluid Intelligence is the type of intelligence that indicates a person's ability to reason quickly and abstractly. It allows for problem-solving, pattern recognition, and decision-making. Crystallized Intelligence, on the other hand, involves the application of knowledge, skills, and experience.
Explanation:
The type of intelligence that refers to a person's ability to reason speedily and abstractly is Fluid Intelligence. Fluid intelligence is the capacity to think logically and solve problems in novel situations, independent of acquired knowledge. This deals with our ability to reason in-the-moment and abstractly. It involves things like problem-solving, pattern recognition, and decision-making.
On the other hand, Crystallized Intelligence refers to the ability to use knowledge, skills, and experience. This form of intelligence grows as we age and accumulate new knowledge and understanding. Mechanical and Pragmatic Intelligence are not recognized types of intelligence in the field of psychology.

Answer:
during external respiration
Explanation:
Oxyhemoglobin is a type of hemoglobin carrying oxygen which is bright red in color. In the blood, it's major function is to carry oxygen molecules throughout the body.
Oxyhemoglobin is formed during external respiration. External respiration also known as breathing occurs in the lung. During external respiration, there is an exchange of oxygen and carbon-dioxide between the cells of the body and blood vessels. During breathing, oxygen diffuses into the blood, the oxygen then binds with heme in the hemoglobin found in erythrocytes to form oxyhemoglobin.
Answer:
during external respiration
Explanation:
Oxyhemoglobin is a protein formed when hemoglobin is combined with an oxygen molecule during lung respiration, also called external respiration. Its function is to transport oxygen throughout the body.
External breathing is performed when we breathe in oxygen into the body. This oxygen will be used for cells to perform cellular respiration that will be responsible for exhaling carbon dioxide out of our body.
