Answer:
The correct answer is :
q = 0.387
p = 0.613
Explanation:
According to the Hardy Weinberg equilibrium, the frequency of alleles or genetic variation remains constant from generation to generation if there is no external disturbance. Equilibrium of such kind in the real-world not possible however it is found to be effective for a theoretical population. H-W equilibrium can be represented with the help of an equation:
P²+ 2pq+q² = 1
here,
p^2 = AA (dominant same allele frequency)
2pq = Aa (heterozygous frequency)
q^2 = aa (recessive similar alleles frequency)
so from the equation:
Frequency of aa = q^2 = 150/1000 = 0.15
Frequency of 'a' = q = square root of 0.15 = 0.387
Freuqency of 'A' = p = 1- 0.387 = 0.613

How are the layers of rock (strata) helpful in determining the age of the fossils found in them?
Answer:
The rock layers help by preserving the fossils and it also keeps a record of how they died, where they lived, what they ate, and a million other factors. Most rock layers are trillions of years old and it shows us what was alive and how they lived and what the earth was like back then.

Which the following represents the proper sequence of steps in the scientific method a hypothesis procedure results conclusion be procedure results hypothesis conclusion see results conclusion hypothesis procedure de conclusion procedure hypothesis result
Answer:
:)
Explanation:
At the core of biology and other sciences lies a problem-solving approach called the scientific method. The scientific method has five basic steps, plus one feedback step:
1. Make an observation.
2. Ask a question.
3. Form a hypothesis, or testable explanation.
4. Make a prediction based on the hypothesis.
5. Test the prediction.
6. Iterate: use the results to make new hypotheses or predictions.
The scientific method is used in all sciences—including chemistry, physics, geology, and psychology. The scientists in these fields ask different questions and perform different tests. However, they use the same core approach to find answers that are logical and supported by evidence.
similarities between triglycerides and glucose
Answer: There, your body turns glucose into energy. Insulin also allows your body to use triglycerides for energy. A common cause of high triglycerides is excess carbohydrates in your diet. High TG's signals insulin resistance; that's when you have excess insulin and blood sugar isn't responding in normal ways to insulin

Select the chemical activity, chosen from the list below, that is
best described by the statement shown.
Either lactic acid or ethyl alcohol is produced as a waste
product of this process.
A
Dehydration synthesis
Aerobic respiration
B
Enzymatic hydrolysis
D
Anaerobic respiration
Answer:
D Anaerobic respiration
Explanation:
The product of anaerobic respiration is the formation of either lactic acid (lactate) or ethyl alcohol as a waste product.
Anaerobic respiration is a process that occurs in the absence of oxygen gas.When oxygen is lacking in cells, glcolytic process follows the anaerobic path way. This process produces very little energy for the body. During a period of intense exercise, anaerobic respiration usually occurs.A biome is large community of organisms occurring a major habitat.

Explain the role of valence electrons and how they relate to the periodic table of elements?
Plz this i really need to finish this.
Explanation:
The valence electrons determine the group the elements belong in the periodic table. For example, the element sodium, Na, has a valence electron of one and so it belongs to Group 1 in the periodic table. Another example is Aluminium, Al, which has a valence electron of three and therefore it belongs to Group 3 in the periodic table.

In the cell membrane, the molecules which move large molecules into and
out of the cell are known as what?
Answer:
ENDOCYTOSIS AND EXOCYTOSIS: MOVEMENT OF LARGE PARTICLES
Explanation:
It is possible for large molecules to enter a cell by a process called endocytosis, where a small piece of the cell membrane wraps around the particle and is brought into the cell. If the particle is solid, endocytosis is also called phagocytos.

Which is the MOST accurate description about how the different types of feed mechanisms work.
A. Both positive and negative feedback loops amplify a departure from the set point.
B. Both to negative and positive feedback loop returns to the set point in the reverse direction
C. Positive feedback loops return to the set point in reverse direction, why negative feedback loops amplify the departure from this point.
D. Negative feedback loops return to the set point in reverse,wow positive feedback loops amplify a departure from the set point
Answer:
D
Explanation:
Positive feedback loops are rarer than negative ones because of homeostasis, but they do occur. Negative feedback loops return to the set point in reverse, and positive feedback loops amplify a departure from the set point.
When combined in the correct ratio, hydrogen and oxygen atoms can form water as show below.

O
O
Hydrogen
Oxygen
Water
In this example, water is an example of which of the following?
Molecules of an element
Molecules of a compound
Atoms of a compound
A mixture
Answer:
B
Explanation:
i took the test
The correct option is (B). Molecules of a compound.
What do you mean by molecules?A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.
Moreover, molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules, such as proteins and DNA, can be made up of many thousands of atoms.
Hence, the smallest particle of any substance which can exist independently and retain the physical and chemical properties of the substance, made up of one or different elements is a molecule.

A mutation in the upland cotton plant causes the development of
chloroplasts with a single outer membrane and no internal membranes.
Which of the following would most likely be observed in chloroplasts of
cotton plants with this mutation?*
Answer:
This question is incomplete as it lacks options. The options are:
A) They would be unable to remove waste products because internal transport proteins would not be present
B) They would be unable to generate ATP and NADPH needed to make sugars because these processes occur on membranes within the chloroplast
C) They would be unable to take up carbon dioxide because CO2 is transported into the chloroplast in membrane-bound vesicles.
D) They would be unable to move within the cell because only organelles with double membranes are mobile.
The answer is B
Explanation:
Chloroplast is an organelle within the cells of certain organisms including plants. It is the site of photosynthesis in autotrophic organisms i.e. organisms capable of making their own food. The chloroplast is double-membraned, like most eukaryotic organelle, made up of inner and outer membrane.
The membranes of the chloroplast contains structures such as thylakoid, where the light dependent reactions of photosynthesis that produces ATP and NADPH needed to produce sugars, take place. Hence, a mutation in the upland cotton plant that causes the development of chloroplasts with a single outer membrane and no internal membranes will make the chloroplasts of this cotton plant be unable to generate ATP and NADPH needed to make sugars because these processes occur on membranes within the chloroplast.

can a cell can survive even if the process to produce ATP is disrupted?
Answer:
No, because ATP provides energy for cells in order for them to carry out their functions. If disrupted it will cause the transport chain to stop which causes ATP to stop and the cells can no longer carry out their functions and will die.
