The ability to refrain from visiting an arm of the radial arm maze more than once on a given test is a measure of C) working memory.
An apparatus known as the radial arm maze is made up of a circular center compartment from which eight equally spaced "arms" extend. The far end of each arm may contain a reward, typically food-based, that cannot be seen from the center compartment. Each arm is an equally long column.
The temporary storage of this kind of information is referred to as working memory. Working memory, in contrast to long-term memory, which describes the temporary, limited holding of information used in tasks like the radial arm maze, describes the ability to recall information from a long time ago. Since testing in the outspread arm labyrinth is done either in one meeting or in different meetings which happen with hardly a pause in between, it is a compelling trial of both reference and working memory.

If the allele for tall stems (T) is dominant to that for dwarf stems (t) and the allele for axial flowers (A) is dominant to that for terminal flowers, then the possible genotypes for a pea plant with tall stems and axial flowers may be TTAA TTaa, TtAA and TtAa.
What is a dominant allele?In genetics, a dominant allele is a gene variant that mask the expression of another gene variant for the same locus, which is then referred to as the recessive allele.
In this case, we have two alleles from different loci (i.e. tall stem T allele and axial flowers A allele) that dominate to other two alleles (i.e., the dwarf stems and the allele for terminal flowers, respectively).
Therefore, with this data, we can see that the dominant alleles are those that mask the expression of the recessive alleles in heterozygous individuals.

Answers
The population of cougars at the beginning of year 2 was calculated to be 392.
The population density is the number of cougars per square kilometer.
Given,
Area- 600 square miles which is equal to 1553.99 sq. km.
The total number of cougars at the end of year 2 was 392
So the population density can be calculated as
Population density = Total population/ Total area.
= 392/ 1553.99
= 0.252
The rate of population growth(r) was calculated to be 0.77
The population size (N) is 392
To calculate the carrying capacity K() the formula is
K= rN(1-N)/CP
K= -0.77×392 (1-392)/3
K= -301.8 × -391/3
K = 39,234
So the carrying capacity was calculated to be 39,234.

Plant cells contain chloroplasts, but zebra cells do not. D. Plant cells contain mitochondria, but zebra cells do not.
Answers
Answer:
Plant cells contain chloroplasts, but zebra cells do not
Explanation:
Chloroplasts in a plant cell are organelles that perform photosynthesis. A plant makes its energy/food from photosynthesis. Zebra cells, however, do not have chloroplasts. Therefore, zebras get their food from plants, and etc.
Plant cells contain chloroplasts, but zebra cells do not which why plants are
the primary producers in an ecosystem.
Plants produce their food through photosynthesis which involves the light
energy, oxygen and water. The light energy from the sun is trapped by the
chloroplast and used in the photosynthetic processes. Light energy is
converted to chemical energy which is used a food by the consumers.

C.
Between zero and twenty-seven degrees Celsius, the rate of the reaction decreases as the temperature increases.
D.
Between sixty and one hundred degrees Celsius, the rate of the reaction decreases as the temperature increases.
Answers
Answer:
the answer is A.
Explanation:
B and C are wrong because they are describing the opposite of what is happening in the graph. D is wrong because there is no change in the reaction rate between 60 degrees and 100 degrees.
The rate of the reaction rises with temperature between zero and twenty-seven degrees Celsius, hence option A is correct.
How does enzyme activity is affected?At various temperatures, catalase functions in different ways. The catalase enzyme becomes more active as the temperature rises from 0°C to about 30°C Up to 100°C, and catalase activity declines as the temperature rises.
The hydrogen bonds between molecules of hydrogen peroxide relax as the temperature rises toward the optimal point, facilitating catalase's reaction with the molecules.
Temperature raising speeds up a process, and lowering temperature slows it down. If the temperature rises over the optimal range, the enzyme denatures and its structure is destroyed.
Therefore, but extremely high temperatures can denature an enzyme, causing it to lose its form and cease functioning. Every enzyme has a preferred pH range, hence option A is correct.

2.) The crossing-over (regional exchange of genetic information) occurs between homologous
chromosomes. WHY is it critical that only homologous chromosomes exchange information?
3. Why is it important that crossing-over takes place between the chromosomes from two
different parents? (answer on back).
Answers
The labels above represent different alleles of genes located on chromosomes. It is critical that only homologous chromosomes exchange information during crossing-over because homologous chromosomes have similar genes in the same order.
The labels above represent different alleles (versions of a gene) that are located on the chromosomes. Capital letters represent dominant alleles, while lower-case letters represent recessive alleles. Different letters represent different genes, and their locations on chromosomes are also different.
It is critical that only homologous chromosomes exchange information during crossing-over because homologous chromosomes have similar structures and genetic content, making it possible for them to align and exchange segments of DNA. If non-homologous chromosomes were to exchange information, the resulting genetic material would be unstable and could lead to genetic disorders or other problems.
It is important that crossing-over takes place between chromosomes from two different parents because it increases genetic diversity in offspring. Each parent contributes one set of chromosomes, and crossing-over allows for the exchange of genetic information between these sets, leading to new combinations of traits. This is important for the survival of a species as it enables adaptation to changing environments and increases the chances of finding new beneficial traits.

A fly has two alleles for the color of its eyes. The green allele is recessive, and

Homozygous dominant+ Heterozygous + Homozygous recessive = 1
OA. 0.72
B. 0.28
C. 0.53
D. 0.47
✓
p+2pq+q² = 1
Answers
The frequency of the dominant blue allele, represented by p, is D. 0.47. This means that 47% of the creatures in the population have the blue eye colour allele.
The equation p + 2pq + q² = 1 represents the Hardy-Weinberg equilibrium equation, which describes the frequencies of alleles in a population.
In this case, p represents the frequency of the dominant blue allele, q represents the frequency of the recessive green allele, and p + q = 1 because these are the only two alleles in the population.
Given that 28 out of 100 organisms are green (q² = 28/100), we can find the value of q. Taking the square root of q², we get q = √(28/100) = 0.53.
Since p + q = 1, we can substitute the value of q to find p. Therefore, p = 1 - q = 1 - 0.53 = 0.47.
So, the value of p, representing the frequency of the dominant blue allele, is 0.47. This indicates that 47% of the organisms in the population have the blue allele for eye color. Therefore, Option D is correct.

First, they are asked to ride a stationary bike for 1 hour in a pollution-free air chamber. A week later, the 50 volunteers return and are again asked to ride a stationary bike for 1 hour in a chamber filled with air pollutants common to Los Angeles. Their heart rates are monitored throughout the 1 hour bike rides. Name the control group Name the experimental group Name the independent variable Name the dependent variable
Answers
Answer:
Control group: volunteer stationary bike riders in a pollution-free chamber
Experimental group: volunteer stationary bike riders in a chamber filled with air pollutants common to Los Angeles
Independent variable: exposure to air pollution
Dependent variable: The heart rates (physical fitness) of the volunteer riders.
Explanation:
In a scientific experiment, data is compared between the control group and experimental group to ascertain the effect of the independent variable on the dependent variable. A control group is the group in an experiment that is not treated with the independent variable i.e. the independent variable is controlled while the experimental group is the group that is treated with an independent variable.
N.B: The independent variable is the variable controlled by the experimenter in order to influence the dependent variable (measurable outcome).
In this experiment, the independent variable is the AIR POLLUTION the volunteer riders are exposed to while the dependent variable is the PHYSICAL FITNESS/ HEART RATES of the volunteer riders, which is dependent on the exposure to air pollution (independent variable).
The control group in this experiment is the volunteer riders placed in a POLLUTION-FREE CHAMBER where the independent variable cannot influence or have any effect on the measurable variable (dependent). The experimental group is the volunteer riders placed in a CHAMBER FILLED WITH AIR POLLUTANTS. The independent variable (air pollution) has been changed in the experimental group.
