Answer:
First thing is that word “autonomous” given in the question is actually “ autosomal”.
Now let's start solution:
Frequency of dominant allele “A” is denoted by p.
Here p = 0.6
Frequency of recessive allele “a” is denoted by q.
According to Hardy - Weinberg equilibrium
p + q = 1
Hence q = 1 - p = 1 - 0.6 = 0.4
Now in question what is asked is about frequency of recessive phenotype (aa).
According to Hardy - Wienberg equilibrium frequency of recessive phenotype is q2 (q square).
Frequency of recessive phenotype is = q2 = 0.4 x 0.4 = 0.16
Now Number of recessive phenotype in a population of 10000 is
= frequency of recessive phenotype x total population
= q2 x 10000
= 0.16 x 10000
= 1600

Al wonders if adding salt to water will affect how long it takes the water to freeze. Al thinks that salt water will freeze more quickly than fresh water. He decides to check his hypothesis by conducting an experiment. Al takes two ice trays and fills one with distilled water and the other with distilled water that has two tablespoons of salt added. He makes sure he puts exactly the same amount of water in each ice tray. Al takes the trays and puts them side by side in the freezer. Al checks the ice trays every 10 minutes to see if the water in each tray has begun to freeze. Al finds that after 20 minutes the water in the ice tray without the salt has started to form ice, while the ice tray with the salt water is still completely liquid.
What is his hypothesis?
a. Salt water freezes slower than fresh water.
b. Water freezes in a freezer
c. Salt water freezes faster than fresh water.
d. water will freeze in 20 minutes
salt water freezes slower than fresh water
What does the QRS complex represents as??
Answer:give me brainliest
Explanation:
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. Ventricular depolarization occurs in part via an accessory pathway (AP) directly connecting the atrium and ventricle and thus capable of conducting electrical impulses into the ventricle bypassing the AV-His Purkinje conduction system.This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.
Explanation:
QRS complex represents as ventricular depolarisation

How do bacteria obtain energy to carry out their functions
Answer:
Bacteria can obtain energy and nutrients by performing photosynthesis, decomposing dead organisms and wastes, or breaking down chemical compounds. Bacteria can obtain energy and nutrients by establishing close relationships with other organisms, including mutualistic and parasitic relationships.
Explanation:
The term voltage describes the:
-electrical potential difference between two points.
-likelihood that an electrochemical gradient will develop.
-process of molecules moving from an area of high concentration to low
concentration.
-way in which osmosis determines water movement.
Answer:
electrical potential difference between two points.
Explanation
Voltage refers to the electrical potential difference between two distinct points. It doesn’t describe the way in which osmosis determines water movement (osmotic pressure), nor does it describe the process of molecules moving from an area of high concentration to low concentration (diffusion), or the likelihood that an electrochemical gradient will develop.
The term voltage describes the electrical potential difference between two points. Option A is correct.
Voltage is a measure of the amount of energy that is available to move electrons from one point to another. It is measured in volts (V). The higher the voltage, the more energy is available to move electrons.
The electrical potential difference between two points is created by the difference in the number of electrons at those two points. If there are more electrons at one point than at another, there will be a voltage difference between the two points. This voltage difference will cause electrons to flow from the point with more electrons to the point with fewer electrons. Option A is correct.

You are in charge of genetically engineering a new organism that will derive all of its ATP from sunlight by photosynthesis. Will you put the enzymes of the citric acid cycle in this organism
Answer:
Yes.
Explanation:
I will put the enzymes of the citric acid cycle in this organism so that in the absence of sunlight, it also produces energy to grow quickly. Citric acid cycle is a series of chemical reactions which release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. This cycle is also called Krebs cycle so incorporation of this cycle is good for the organism.

b. found in the cytoplasm of eukaryotic cells.
c. a system of tracks used for transport.
d. composed of microtubules and microfilaments.
e. All answers are correct.
Answer: e
Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.
1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.
2. The cytoskeleton provides support and shape to cell.
3. It help in transporting substances through cell.
4. It help in phagocytosis.
5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.
6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.
All answers are correct. Therefore, option (E) is correct.
What is cytoskeleton?The cytoskeleton is a complex network of protein filaments that extends throughout the cytoplasm of eukaryotic cells. It plays a number of important roles in the cell, including providing structural support, helping cells maintain their shape, and assisting in the movement of organelles and other cellular components. The cytoskeleton is also involved in the process of cell division, or mitosis, which is the process by which a single cell divides into two daughter cells.
The cytoskeleton is composed of three types of protein filaments: microtubules, microfilaments, and intermediate filaments. Microtubules are long, thin protein fibers that form a kind of scaffolding within the cell. Microfilaments, which are made of actin proteins, are thinner than microtubules and are involved in muscle contraction and cell movement. Intermediate filaments are thicker than microfilaments and provide structural support to the cell. Together, these three types of protein filaments form a system of tracks that can be used for transport within the cell.

Which of the following changes to Earth is caused predominantly by living organisms?
A. The production of dirt.
B. The release of free nitrogen into the atmosphere.
C. The release of sulfur dioxide into the atmosphere.
D. The movement of air currents by convection cells.
The production of dirt is cause predominantly by living organisms
This production can be caused through emission of pollution in the form of air, water, soil, noise or e-waste.
What is Pollution?Pollution is defined as the introduction of unwanted harmful elements in the form of release of gaseous toxic substances which result into polluting the environment.
These pollutants can be both natural and anthropogenic.
Natural pollutants are volcanic ash, river sediments
Anthropogenic pollutants are chemicals released from industries vehicular emission.
Majorly pollution are of four types- Air, Water, Soil and Noise. Recently another pollution in the form of e-waste is also prominent.
Effects of pollution on environment:
1. Biomagnification describes situations where toxins (such as heavy metals) passes through trophic levels, becoming exponentially more concentrated in the process.
2. Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO2 becomes dissolved.
3. The emission of greenhouse gases leads to global warming which affects ecosystems in many ways.
4. Nitrogen oxides are removed from the air by rain and affect the land which can change the species composition of ecosystems.
5. Smog and haze can reduce the amount of sunlight received by plants to carry out photosynthesis and leads to the production of tropospheric ozone which damages plants.
6. Sulfur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.
7. Organic pollution of watercourses can deplete oxygen levels and reduce species diversity.
Rest three options are majorly natural process.
Option B focuses on release of free nitrogen into atmosphere which is one of the important step of Nitrogen Cycle.
Option C focuses towards release of Sulfur Dioxide into atmosphere. This process is caused either naturally or anthropogenically. Thus cant blame solely the anthropogenic factor for its release.
Option C is the total natural process i.e. Climatological Process where air currents are regulated by Convection Cells and regulate based on different natural factors.

1. Describe the purpose of mitosis.
2. Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis
Answer:
1) The purpose of mitosis is growth and repair of cells
Explanation:
Prophase:
-DNA condenses (supercoiled, chromatids are visible under light microscope);
-Nuclear membrane begins to disintegrate (by the end of prophase it is completely gone)
-Centrioles move to opposite ends of the cell
-Splinde fibers start to form from the centrioles and grow
Metaphase:
-Spindle fibers, departing from both poles, are attached to each centromere, on opposite sides
-The spindle fibers pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the equatorial plane
Anaphase:
-The spindle fibers shorten
-The centromeres of sister chromatids split
-Chromatids move apart, pulled by the spindle fibers
-Chromatids become chromosomes
-Half of the chromosomes move to one cell pole, half to the other
Telophase:
-The chromosomes reach the cell pole
-Nuclear membrane reforms
-Spindle fibers break down and disappear
-The chromosomes begin to uncoil, which makes them diffuse and less compact
Cytokinesis:
-The cell membrane pinches inward until the cell divides in two;
-There are two daughter cells with the same structures and number of chromosomes as the parent cell
-Chromosomes decondense
How are human affiliative and aggressive behaviors different from what is seen in nonhuman primates? Provide specific examples.

How would the carbon cycle be influenced by an increase in aerobic respiration?
Answer:
Cellular respiration does not affect the carbon cycle but is part of the carbon cycle. The 2 carbon cycles. carbon ( C ) is taken up by the plants and trees in the form of carbon dioxide ( CO2 ). Plants converts this CO2 into organic compounds such as glucose ( C6H12O6 ).
Explanation:
Increase in aerobic respiration will lead to increase in the amount of CO2 released into to the atmosphere due to respiration.
Aerobic respiration occurs when oxygen is combined with glucose to yield carbon dioxide and water. This is one of the major ways through which carbon dioxide enters the carbon cycle.
Note that the carbon cycle shows the movement of carbon in nature. Increase in aerobic respiration means that more carbon will be introduced into the atmosphere as carbon dioxide.

Psychometric scores for anxiety, depression, negative self, somatization, and hostility were combined into a single Global Severity Index (GSI). Global Severity Index was compared for 80 adolescents who were seen in the outpatient clinic for 7 different physical complaints (short stature, obesity, lack of weight gain, breast problems, genital problems, menstrual problems, and hirsutism). Report the degrees of freedom for the relevant F statistic in the numerator and the denominator. (Round your answers to the nearest whole number.)
Answer:
The correct answer is -
Numerator = 6
Denominator = 73
Explanation:
In F static test or table there are two sets of degrees of freedom: one for the numerator and one for the denominator. The degrees of freedom are equal to the number of observations minus one. Thus, if the sample size were 7 then the degree of freedom would be 7 minus 1
Numerator df = 7 - 1 = 6
Thus, the numerato would be - 6.
Denominator is calculated by subtracting the observation or variables from the total number of sample size.
Denominator df = 80- 7 = 73
