Which stage is the last stage of speciation? question 5 options: the populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring. The populations successfully interbreed. The populations become totally separated from one another. The populations are isolated and thus do not interbreed
Answer:
D) The population become adapted to different environments and eventually becomes so different that they cannot interbreed to produce fertile offspring.
Explanation:
Speciation is divided into three stages:
a) Separation.
b) Adaptation.
c) Reproductive Isolation.
Stage 1: Separation.
A part of the population separates and adapts to a new environment. Natural events such as tsunamis, tidal waves can cause organisms to separate from their initial habitat to a new environment.
Stage 2: Adaptation.
At this stage, the organisms evolve new traits that enable them to a new environment. They possess certain characteristics that enable them to fit into the new environment. Example The great white skin's color makes it difficult for it to be seen in the dark.
Stage 3: Reproductive Isolation.
At this stage, organisms of the same species reunite and do not interbreed. Here, species are isolated into new ones so they have the best adaptations for their new habitat.

Decide whether the sentence is grammatically correct or incorrect as written. no repites eso. (don't repeat that.) correct incorrect
Answer:
INCORRECT!!!!!!!
Explanation:
The sentence "no repites eso" is grammatically correct in Spanish, but it is not grammatically correct in English. The correct translation of "don't repeat that" in Spanish is "no repitas eso".
What is sentence?A sentence is a group of words that express a complete thought or idea. It is a fundamental unit of language that conveys meaning to the reader or listener.
A sentence typically consists of a subject, which is what the sentence is about, and a predicate, which describes what the subject is doing or what is happening to it.
A sentence can also contain other elements, such as an object or complement, that further describe or modify the subject or predicate. Sentences can vary in length and complexity, from simple one-word sentences to complex sentences with multiple clauses.
Effective sentence construction is important for clear communication, both in written and spoken language. Skilled writers and speakers use a variety of sentence structures to convey their message with precision and impact.

Please rate and mark brainliest!!
Note that the probability that Micah is included in the group of students chosen is approximately 0.000305, or about 0.03%.
How to compute the above probabilityMicah's probability of being included in the group of students chosen can be calculated using combinations. There are a total of 28 students in the class, and the teacher is selecting 3 students.
The probability of Micah being chosen can be calculated as:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
Number of favorable outcomes = 1 (Micah being selected)
Total number of possible outcomes = Number of ways to choose 3 students out of 28 = C(28, 3) = 3276
Probability = 1 / 3276
≈ 0.000305
So, the probability that Micah is included in the group of students chosen is approximately 0.000305, or about 0.03%.

400 students were randomly sampled from a large university, and 289 said they did not get enough sleep. Conduct a hypothesis test to check whether this represents a statistically significant difference from 50%, and use a significance level of 0. 1
Answer:
The sample proportion represents a statistically significant difference from 50%
Explanation:
The sample proportion is the same as 50%
Alternate hypothesis: The sample proportion is not the same as 50%
z = (p' - p) ÷ sqrt[p(1 - p) ÷ n]
p' is sample proportion = 289/400 = 0.7225
p is population proportion = 50% = 0.5
n is number of students sampled = 400
z = (0.7225 - 0.5) ÷ sqrt[0.5(1 - 0.5) ÷ 400] = 0.2225 ÷ 0.025 = 8.9
The test is a two-tailed test. Using a 0.01 significance level, critical value is 2.576. The region of no rejection of the null hypothesis is -2.576 and 2.576.

In peas, purple flowers are dominant over white flowers. If two heterozygotes are crossed, what fraction of the population will have white flowers?
The fraction of the population will have white flowers after the crossing of the heterozygotes is; 1/2
What is the result of the heterozygote crossing?P = purple gene
p = white gene
Punnet squares shows the possible genotypes and probabilities of each genotype in the offspring of a cross:
Purple flower genotype (heterozygous) = Pp
White flower genotype = pp
Potential genotypes for offspring are Pp and pp;
According to the Punnett square, 2 of 4 offspring will have the Pp genotype and the other 2 will have pp genotypes;
This means 2 should be purple and 2 white which translates to the fact that there is a 50% chance of having either genotype, of being purple or white.

A block of mass 500 g is attached to a horizontal spring, whose force constant is 25. 0 n/m. The block is undergoing simple harmonic motion with an amplitude of 6. 00 cm. At t=0 the block is 4. 00 cm to the left of its equilibrium position and is moving to the right. At what time t1 will it first reach the limit of its motion to the right?
The time taken for the car to reach the limit or amplitude of the motion is 0.33 s.

The equation for the simple harmonic motion of the block is calculated as follows;
y = A sin(ωt + Φ)

In an electrochemical cell, electrons flow from anode to cathode while current flows in the opposite direction.
What is an electrochemical cell?The question is incomplete but it clearly relates to an electrochemical cell so I will answer in a general way. An electrochemical cell consists of a cathode and an anode. The anode is positively charged while the cathode is negatively charged.
We should note that electrons flow from anode to cathode but the flow of current is in the opposite direction. This occurs because the electron is negatively charged.

Nucleophilicity is a kinetic property. A higher nucleophilicity indicates that the nucleophile will easily donate its electrons to the electrophile and that the reaction will occur at the faster rate. The reaction rate also depends on the nature of the electrophile and solvent. Rank the following reactions from fastest to slowest based on the nucleophilicity of the nucleophile
From the fastest to the slowest based on the nucleophilicity of the nucleophiles, the order is represented as:
[tex]\mathbf{(CH_3)_2N^- +CH_3 -Br \to (CH_3)_2NCH_3+Br^- \ }\\ \\ \\ \mathbf{CH_3NH^- +CH_3 -Br \to CH_3NHCH_3+Br^- \ } \\ \\ \\ \mathbf{H_3N^- +CH_3 -Br \to CH_3NH_2 + Br^- \ }[/tex]
What are Nucleophilic functional groups?Nucleophilic functional groups include electron-rich atoms capable of donating an electron pair in order to establish a new chemical covalent bond. The most frequent nucleophilic functional groups are:
Water, Alcohols, Phenols, Amines, Thiols, etcThe protonation state of these functional groups has an effect on their nucleophilicity. Also, the trend of nucleophilicity goes from:
Tertiary,Secondary, PrimaryThe following reactions that we are supposed to find their order is given as follows:
[tex]\mathbf{CH_3NH^- +CH_3 -Br \to CH_3NHCH_3+Br^-} \\ \\ \\ \mathbf{(CH_3)_2N^- +CH_3 -Br \to (CH_3)_2NCH_3+Br^-} \\ \\ \\ \mathbf{H_3N^- +CH_3 -Br \to CH_3NH_2 + Br^-}[/tex]
From the fastest trend of the nucleophilicity of the nucleophile to the slowest, the correct arrangement is as follows:
[tex]\mathbf{(CH_3)_2N^- +CH_3 -Br \to (CH_3)_2NCH_3+Br^- \ \ \ ---(2'' \ ^0) \ \\}\\ \\ \\ \mathbf{CH_3NH^- +CH_3 -Br \to CH_3NHCH_3+Br^- \ \ \ \ ---(1^0) } \\ \\ \\ \mathbf{H_3N^- +CH_3 -Br \to CH_3NH_2 + Br^- \ \ \ --- \ \ \ \ (1^0)}[/tex]

Imagine that 64% of the people living in a remote village in the mountains can taste phenylthiocarbamide (ptc). In order to taste ptc, you must have at least one copy of the dominant ptc taster allele. If the population were in hardy-weinberg equilibrium for the ptc gene, calculate the allele and genotype frequencies as listed below:
If the population were in Hardy-Weinberg equilibrium then the frequency of heterozygous will be 0.48, recessive homo-zygous 0.36 and dominant homo-zygous 0.16.
What is the Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium is a model used in population genetics to estimate genotypic and allele frequencies.
The Hardy-Weinberg equilibrium is p2 + 2pq + q2 = 1. In this case, p2 + 2pq is equal to 0.64.
In consequence, q2 = 1 – 0.64 = 0.36 >> q is equal to 0.6 and p = 1 – 0.6 = 0.4.
Finally, the frequency of heterozygous is 2pq (2 x 0.4 x 0.6) = 0.48, recessive homo-zygous is 0.36 and dominant homo-zygous is 0.16 (1 - 0.48 - 0.36 = 0.16).
