A scientist is researching oil content of seeds from a new plant species named R. artificial. The average oil content from plants in her lab population is 52%, and she has determined the narrow sense heritability (h^2) is 0.60. If she randomly mates individuals with 70%, 71%, 72%, 73%, and 74% seed oil content what is the expected response to selection (R)?
Answer:
The correct answer is - 12%
Explanation:
Given:
Mean of the population - 0.52
Narrow sense heritability or h^2 - 0.6
The expected response of selection or R = ?
Solution:
The average oil content in the selected individuals - 0.7, 0.71, 0.72, 0.73, 0.74
And, the mean of these selected individuals = (0.7 + 0.71 + 0.72 + 0.73 + 0.74) / 5
= 0.72
Formula:
S = Average of selected individuals - Average of population
= 0.72 - 0.52
= 0.20
R = h^2 x S
R = 0.6 x 0.2
= 0.12
= 12%
Thus, the correct answer is - 12%

What is the difference between a protein and a trait
Answer:
The Relationship Between Genes, Proteins, and Traits
A gene codes for a particular protein that is involved in the expression of a trait. Characteristics determined by single genes are called Mendelian traits.
A gene is a stretch of DNA on a chromosome that has the instructions for making a protein. Each chromosome has many genes with humans having over 22,000 genes in all. A gene's instructions for a protein are written in the three letter code I referred to before. A protein is a molecular machine that does a specific job.
Explanation:

Heat Transfer Mechanisms 1.In your own words, using the pennies activity, define the three different heat transfer mechanisms. Your definitions should include:
(i) information about how energy is moving
(ii) what is happening microscopically (that is, at the atomic level)
(iii) what phase(s) of materials is usually involved.
Answer:
The three modes of heat transfer are: 1) Radiation 2) Convection 3) Conduction
Explanation:
RADIATION:
It is the mode of heat transfer which requires no medium because the transfer of energy takes place in the form of electromagnetic radiations. The spectrum of radiations that contribute to the heat transfer via radiation is the wavelength ranging from 0.1 μm to 100 μm.
For example the heat from the sun reaches the earth via radiation that passes through space and then through the atmosphere of the earth.
CONVECTION:
It is the mode of heat transfer that takes place in a fluid matter. The molecules in this case move from one place to another due to the difference in density developed as a result of heat absorption.
Example, the boiling of water. When the water in a utensil is heated, the heat is supplied at the bottom. In such a case the molecules of the water absorb the heat resulting in increased intermolecular spacing and hence the water at the bottom becomes the least dense in the bulk of water mass in the utensil hence rises up at to the free surface of the fluid mass. Then the densest mass of the fluid occupies the bottom space and is heated by the heat source supplied. This chain continues.
CONDUCTION:
This is the process of heat transfer from one molecule to the next neighbouring molecules. The propagation of heat energy occurs in a sequential manner starting from the molecule nearest to the heat source. The microscopic phenomenon happens in the form of lattice vibrations that are responsible for the transfer of heat energy via conduction.
Example, while heating of a pan the base heats up at first being continuously exposed to heat whereas the handle of the pan being far away from the source heats up after a long time.

6) In Medieval times a ruler told the peasants that they were free to take anything from the forest that had fallen, branches, trees, leaves etc. But they were not to take any live standing trees. Within a few years the forest was dying. Why
Answer:
Due to lack of nutrients in the soil.
Explanation:
Within a few years the forest was dying because there is no nutrient is present in the soil which can trigger the growth and development of the sol. The fallen parts of trees such as branches, tree and leaves etc are decomposed by decomposers such as bacteria and fungi which turn the fallen materials into nitrogenous materials which can be used by the plant for its growth and development.

g Two closely related species of plant (A and B) hybridize to form a new species (C). Species A is diploid and has 8 chromosomes. Species B is tetraploid and has 20 chromosomes. -What type of whole genome duplication is this (autopolyploidy or allopolyploidy)
Answer:
allopolyploidy
Explanation:
Polyploidy is the condition by which a cell might have more than two chromosome sets that form homologous pairs. It might occur due to a failure or abnormality in cell division.
Autopolyploidy
Refer to a type of polyploidy in which an organism has more than two copies of homologous chromosomes. It results from the duplication of a group of chromosomes of the same species. Autopolyploid individuals have at least three groups of homologous chromosomes. Autopolyploidy is produced by the gamete fusion of the same progenitor - same species-, duplicating the number of chromosomes of diploid species. The autopolyploid cell has groups of homologous chromosomes. Autopolyploidy is produced mainly due to non-disjunction during meiosis.
Allopolyploidy
Refer to another type of polyploidy in which species have more than three sets of chromosomes in their cells. Allopolyploidy occurs when two different species mate, leading to the fusion of gametes that belong to different species and produce a new hybrid. The chromosomic complement has more than two copies of chromosomes. The hybrid is infertile with the parental species. The allopolyploid cells have chromosome groups that are not homologous.
In the exposed example two different species mate and produce a hybrid species.

You have an experience that causes a complex network of neurons to be built in your brain. This network is most likely a _____. (Mark the one best answer.) ❍ a receptive field❍ B disease❍ C memory❍ D motor pathwa
Answer:
a receptive feild
Explanation:
The complex network of neurons built in response to an experience is most likely a memory.
What is neuron?Neurons are specialized cells that are the basic building blocks of the nervous system. They are responsible for receiving, processing, and transmitting information through electrical and chemical signals.
Memories are encoded in the brain by the formation and strengthening of neural connections between neurons, also known as synaptic plasticity.
When we experience something new, this process of synaptic plasticity is triggered and neurons form new connections or strengthen existing ones to encode the information.
Over time, these connections can become consolidated into long-term memory.
Therefore, when a person has an experience that causes a complex network of neurons to be built in their brain, it is most likely a memory.
