This paramecium has a nucleus and is comprised of one cell. Which terms best describe this organism?
Answers
Answer: The term that best describes this organism is that it's a UNICELLULAR PROTISTA.
Explanation:
Unicellular organisms are that are made up of just one cell. They are also called single- celled organisms. Examples of unicellular organisms include: Amoeba, chlamydomonas and paramecium.
The paramecium is a protist which is SINGLE-CELLED and is made up of eucaryotic cells in which the cell structure is complex with a well-defined NUCLEUS.
The structure of this organism helps it to survive in its environment. It has cilia that helps it move food into its gullet.
The food vacuole circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body. The food vacuoles circulate along a definite path in the cytoplasm. The anterior and posterior contractile vacuole, with radiating channels draining into them, helps to get rid of excess water from the body.
The NUCLEUS is used by the organism for sexual reproduction. This occurs in a process known as conjugation whereby the whole organism pair with another similar whole organism and exchange their nuclei.

Heads Tails
84 66
Which of the following statements best describes the experimental probability of getting heads?
It is equal to the theoretical probability.
It is 6% lower than the theoretical probability.
It is 6% higher than the theoretical probability.
The experimental probability cannot be concluded from the data in the table.
Answers
Answer:
it is 6% higher than the theoretical probability.
Explanation:
we start with out experimental.
84 times heads out of 150.
84/150 = 56.
=56%
now for theoretical.
since there are 2 sides, there are 2 chances of randomly getting heads.
1/2 = 50%
56% > 50%
therefore your answer is that it is 6% higher. hope my explanation helps!
A 20.0 gram sample of a certain radioisotope decays over a
period of 19.2 hours. After that time, only 2.50 g of the isotope
remains. Calculate the half-life.
Answers
quantity of the substance remaining = initial quantity of the substance * (.5)^(time elapsed/half life of the substance)
2.50 = 20 * (.5)^(19.2/x)
The half-life period of the given sample of the radioisotope is equal to 6.41 hours.
What is the half-life period?The half-life of a radioactive substance is defined as the time that is required to reduce the original quantity of a radioactive element to half after decay.
Half-life of a radioactive element is the characteristic of the element and does not depend upon the initial amount of the radioactive substance.
Given, the original amount of the radioisotope, N₀ = 20.0 g
The remaining amount of the radioisotope, N = 2.50 g
The time for which decay occurs, t = 19.2 hours
Consider that k is the rate constant of the decay of radioisotope,
[tex]k =\frac{2.303}{t} \times log \frac{N_0}{N}[/tex]
[tex]k =\frac{2.303}{19.2} log \frac{20}{2.50}[/tex]
k = 0.108 hr⁻¹
The half-life time of radioisotope can be calculated from the below mentioned formula:
[tex]t_{\frac{1}{2}} =\frac{0.693}{k}[/tex]
[tex]t_{\frac{1}{2}} =\frac{0.693}{0.108}[/tex]
[tex]t_{\frac{1}{2}} =6.41 hrs[/tex]
Therefore, the half-life period of the given sample of the radioisotope will be to 6.41 hours.

The phenotype of individuals and the environment where they live, interact and determines the genes´ destiny in space and time. The result of this interaction and the gene destiny is Natural Selection. Natural selection selects beneficial alleles and increases their frequency in the population.
The attack by snakes is acting as a selective pressure on the frogs´ population. It is an ecological pressure that is modeling the frogs´ phenotype.
Animals that suffer more attacks are the blue ones, followed by green and red frogs. Those that suffer the fewest number of attacks are the yellow individuals.
So natural selection will be acting on this population favoring the alleles that code for yellow color. Genes that express yellow color increase more the frogs´ fitness than genes that code for the other colors. So natural selection increases the frequency of genes coding for yellow color and will decrease the frequency of the other alleles. Probably the less favored will be genes that express blue.
How can noise pollution harm wildlife?
A. It confuses organisms that rely on cycles of day and night.
B. It removes essentials nutrients from organisms’ habitats.
C. It prevents animals from catching prey or escaping predators.
D. It increases the body temperatures of organisms to harmful levels.
Answers
C. It prevents animals from catching prey or escaping predators is the correct option.
What is noise pollution?Noise pollution also understood as environmental noise or sound pollution, exists as the propagation of noise with ranging consequences on the activity of human or animal life, most of them detrimental to a degree. The source of outdoor noise worldwide exists mainly caused by machines, transport, and propagation techniques.
Noise pollution also understood as environmental noise exists as the propagation of potentially “damaging” sounds via the environment. The impacts of noise pollution tend to be seen as a nuisance rather than an environmental concern for decades.
Noise pollution harm wildlife by preventing animals from catching prey or escaping predators.Due to noise pollution the prey organisms do not come out from their habitat. It becomes difficult for the predator to catch their prey if they do not comes out. Also prey organisms gets frightened and fails to escape from their predators.

e. The downhill movement of electrons through the ETC creates a proton gradient across the inner mitochondrial membrane. The _________________ subunit of the ATP synthase creates a channel that allows for the downhill movement of protons from the intermembrane space to the matrix.
f. The concomitant release of free energy drives the synthesis of ATP by the ____________ subunit of that same protein.
Answers
Answer:
a. NADH
b. Ubiquinone
c. Cytochrome c
d. Oxygen
e. F0 subunit
f. F1 subunit
Explanation:
Electrons enter the Electron Transport Chain (ETC) from Nicotinamide Adenine Dinucleotide (NADH), which is an electron donor generated during different catabolic reactions (e.g., glucose oxidation). Ubiquinone or 'Coenzyme Q' is an electron acceptor that accepts electrons from both Complex I and Complex II and donates electrons to Complex III. The oxygen (O) is the final electron acceptor that accepts the electrons after they have passed through the ETC and ATPase. Complex III (also known as Ubiquinol-cytochrome c oxidoreductase) catalyzes the electron transfer from ubiquinol to Cytochrome c, which is coupled to proton translocation across the membrane. The F0 subunit of the ATP synthase forms a channel (embedded in the mitochondrial membrane) through which protons can flow. Moreover, the F1 subunit of the ATP synthase uses the energy released by the proton electrochemical gradient to drive the synthesis of ATP.
Which description accurately describes the cell membrane?
a. a single permeable layer of phospholipids that have hydrophobic heads and hydrophilic tails
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
c. a single permeable layer of phospholipids that have hydrophilic heads and hydrophobic tails
d. a semi-permeable double layer of phospholipids that have hydrophobic heads and hydrophilic tails
e. a barrier of polypeptides that prevents molecules from entering or leaving the cell
Answers
Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.
Hope this helped!
