Explanation:
Why do you think ANIMAL CELLS are able to survive without the types of cell walls that are present in nearly every other group of organisms? Provide 3 answers.
Answer:
They survive because these cells need a high permeability to be able to maintain the internal cellular balance in relation to the external environment that surrounds them, and this is due to their high energy demand, their multi-complex and multiple functions, and the capacity for constant homeostasis with the environment. that surrounds them.
Explanation:
In addition, some cells need to transmit signals, second messengers or even to fulfill a function to exchange compounds for their transmembrane, this is what makes the human system together with other systems of other animals is extremely open and is in constant energetic exchange, in addition to Unlike plant cells, plant cells are under an autonomous regime, they do not need to take energy from the environment but they manufacture it themselves, and it fulfills a great function that is to provide structure and support, the wall they have is what gives it the ability to fulfill these two functions.

You want to know if black squirrels or brown squirrels have a greater birth rate. Your ALTERNATIVE hypothesis is:_________.
Answer:
Natural selection is a mechanism of evolution proposed by Charles Darwin. It is the differential survival and reproduction of individual due to the difference in the phenotype. Over time, this process results in populations which are better adapted to their environment as they tend to survive and produce new offspring. The brown squirrels with thick coat survive at a higher rate than the brown sqirrels without the thick coat. Thick coat is a adaptation for survival in cold winters which are chosen over the other and allowed to reproduce.

The term semiconservative replication refers to the fact that each new DNA molecule resulting from the replication process is "half-old, half-new." In the diagram, complete the replication required in the
middle of the molecule by adding the required letters representing the missing nucleotide bases. Recall
that ATP energy and the appropriate enzymes are actually required to complete this process.

1. A
2. C
3. T
4. G
5. G
6. G
7. T
8. G
9. A
10. C
11. C
12. C
Explanation:
As stated in this question, Semi-conservative model of DNA replication is the acceptable model of replication in which the two synthesized molecules of DNA consists of one new and one old strand each. DNA replication is carried out by an enzyme called DNA polymerase.
In the semi-conservative model, a double stranded DNA separates into two single strands. Each single strand is used as a template for DNA polymerase to synthesize nucleotides based on complementary base pairing i.e. For every Adenine base, Thymine is added and for every Guanine, Cytosine is added and vice versa.
In this question showing an image of a DNA molecule undergoing replication using semiconservative model, the first DNA molecule consists of the following nucleotides on the old strand and its synthesized nucleotides on the new strand:
Old strand - New strand
1. T - A
2. G - C
3. A - T
4. C - G
5. C - G
6. C - G
On the second DNA molecule, we have the following nucleotides on the old strand and its synthesized nucleotides on the new strand.
Old strand - New strand
7. A - T
8. C - G
9. T - A
10. G - C
11. G - C
12. G - C

Which statement best summarizes the differences between these two diseases? (SC.6.L.14.6)a.Viruses can replicate because they are living organisms, while bacteria cannot. b.Viruses are not living organisms, but bacteria are living. c.Viruses can be beneficial to live organisms but bacteria are often infectious. d.Viruses are living organisms, while bacteria are not.
Answer:
Eblow is a terrible thing.
Explanation:
Answer:
I think its, option b) Viruses are not living organisms, but bacteria are living.
Explanation:
The other options don't fit "summarize the differences b/w bacteria and virus", or simply don't make sense...
Bacteria can replicate as well, not only virus, so that cannot be a difference
The virus is often the one being more dangerous, there is something called "good bacteria"
A virus isn't living, (for the sake of this answer), and we all know for sure that bacteria is living
So, that's how option b is correct

Based on your knowledge of reproduction in bryophytes and ferns, is the presence of flagellated sperm in cycads surprising? Why or why not?
Answer:
The correct answer is - All plants share a similar life cycle
Explanation:
The sperms that the bryophytes are biflagellated whereas in ferns these are multi-flagellated that helps in the swimming to the archegonia or female part to perform the fertilization, due to the presence of water.
The sperms in cycads also have flagella for the same purpose of swimming in the pollen tube. The ferns and the bryophytes both require the same or similar life cycle that includes the flagella and water for the formation of the zygote.

Succession Interactive!
What is the difference between primary succession and
secondary succession?
Primary succession occurs in an area that is disrupted by a
fire or other natural disaster but secondary succession does
not.
Primary succession occurs after secondary succession.
Primary succession involves only plants but secondary
succession involves animals too.
Primary succession occurs in an area with no life and no soil
but secondary succession happens in an area where an
existing community was disrupted.
Answer:
Primary succession occurs in an area with no life and no soil but secondary succession happens in an area where an existing community was disrupted.
Explanation:
Ecological succession, which is the series of changes that occurs in an ecosystem over a period of time, can be divided into two types namely: primary succession and secondary succession.
- Primary succession is a kind of succession in which a bare surface or rock is colonized by certain organisms called PIONEERS. Primary succession occurs in an area with no life and no previous soil.
- On the contrary, secondary succession occurs in an area that has been previously colonized but disturbed as a result of natural occurrences e.g earthquake, wildfire, flooding etc.
Notice on the graph that the time period between 0 and 3 minutes forms a straight line on the graph.
What does this indicate about the rate of the reaction?
Answer:
The graph is positive.
Explanation:
Straight line on the graph indicates that the rate of reaction is positive which means that reaction intensity increases with the passage of time. OR in other words, the reaction produces more products with the passage of time and no decrease occurs in their rate because the graph is not coming downward or changing so that's why the graph go in the straight line.

Suppose we stock a pond with 100 fish and note that the population doubles in the first year (with no harvesting), but after a number of years, the population stabilizes at what we think must be the carrying capacity of the pond: 2,000 fish. Growth seems to have followed a logistic curve. a. What population size should be maintained to achieve maximum yield, and what would be the maximum sustainable fish yield? b. If the population is maintained at 1,500 fish, what would be the sustainable yield?
Answer:
Explanation:
From the given information,
The first process is to determine the initial growth rate by using the formula:
[tex]R_o = \dfrac{In(2)}{t_d}[/tex]
where;
The initial growth rate(constant) = [tex]R_o[/tex] ; &
the doubling time = [tex]t_d[/tex] = 1 year
[tex]R_o = \dfrac{In(2)}{1 \ year}[/tex]
[tex]R_o[/tex] = 0.693 / year
Now, we move up to the net stage to find the growth constant by using the formula:
[tex]r = \dfrac{R_o}{(1 - \dfrac{N_o}{K})}[/tex]
where;
[tex]N_o[/tex] = population of fish in the pond = 100
[tex]R_o[/tex] = The initial growth rate(constant) = 0.693 /year
K = carrying capacity = 2000
Then;
[tex]r = \dfrac{0.693 \ /year }{(1 - \dfrac{100}{2000})}[/tex]
[tex]r = \dfrac{0.693 \ /year }{(1 - 0.05)}[/tex]
[tex]r = \dfrac{0.693 \ /year }{(0.95)}[/tex]
r = 0.730 / year
a)
Now, the maximum yield can be evaluated by using the expression:
[tex]= \dfrac{rk}{4}[/tex]
[tex]= \dfrac{0.730 \times 2000}{4}[/tex]
= 365 fish per year
Also, the maximum sustainable yield is said to be half of the carrying capacity suppose that the population growth obeys logistic curve;
i.e.
[tex]N' = \dfrac{1}{2} \times 2000[/tex]
N' = 1000 fish
b)
If the population is maintained at 1500 fish;
The sustainable yield can be calculated by using the formula:
The Sustainable yield = [tex]r\times N (1 - \dfrac{N}{K})[/tex]
The Sustainable yield = [tex](0.730/ year ) (1500) (1 - \dfrac{1500}{2000})[/tex]
The Sustainable yield = 1095 × 0.25
The Sustainable yield = 273.75 fish per year
The Sustainable yield ≅ 274 fish per year
Population size should be maintained to achieve maximum yield and Sustainable yield if population is maintained at 1,500 fish are 364.7 , 273.525 fish per year
Sustainable yield:Given that;
Stock in start = 100 fish
Double in 1 year
Capacity of pond = 2000 fish
Find:
Population size should be maintained to achieve maximum yield
Sustainable yield if population is maintained at 1,500 fish
Computation:
Growth rate = ln₂ / 1
Growth rate = 0.693 per year
With no growth constraint r = [tex]\frac{0.693}{1-\frac{100}{2000} }[/tex]
With no growth constraint r = 0.7294 per year
A. Population size should be maintained to achieve maximum yield = [tex]\frac{0.7294 \times 2000}{4}[/tex]
Population size should be maintained to achieve maximum yield = 364.7 fish per year
B. Sustainable yield if population is maintained at 1,500 fish = [tex][(0.7294))(1500)][1-\frac{1500}{2000} ][/tex]
Sustainable yield if population is maintained at 1,500 fish = 273.525 fish per year
