Explanation:

I am not completely sure but my research indicates the following in chronological order from the oldest to the newest:

1. Prokaryotic (about 3.5 to 3.8 billion years ago)

2. Photosynthetic (about 3.4 billion years ago)

3. Eukaryotic (about 2.7 billion years ago)

4. Aerobic (about 2.5 billion years ago)

5. Anaerobic (about 2.4 billion years ago)

6. Multicellular (about 600 million years ago)

Disclaimer: My answer may be incorrect because I am not completely sure but I think this is right.

If you are fine with it, I would appreciate if I got the brainliest answer :)

Answer 2

According to the question the sequence of the cell type is as follows:

Prokaryotic (Approx 3.5 to 3.8 billion years ago) Photosynthetic (Approx  3.4 billion years ago) Eukaryotic (Approx 2.7 billion years ago) Aerobic (Approx 2.5 billion years ago) Anaerobic (Approx  2.4 billion years ago) Multicellular (Approx 600 million years ago)

How did life begin and evolve on Earth?

Many scientists consider that RNA, or similar to RNA, was the first molecule on Earth to self-replicate and initiate the process of evolution that led to more advanced forms of life, including human beings.

Thus, the correct sequence is that.

An S-shaped pattern formed when a stream flows through channels is called

Answers

Answer:

meander

Explanation:

A meander is a series of regular sinuous curves in the channel of a stream/river/watercourse, thereby forming a rounded or "S"-shaped bend curve. Meanders are common in alluvial areas that have low gradients, where they are formed by the dynamics of the watercourse. The meander belt is the zone within which a meandering watercourse occupies on its floodplain. The sinuosity is a measure to calculate the degree of meandering in the channel of a watercourse.

If various physiological responses are constantly adjusting, do you think the body is ever in equilibrium?

No because there is a consistent trade of energy between us. The body won't accomplish that even after it is no longer living since the body rots and this will likewise make a progression of material and energy between the two.

The mutation rate is the probability of a single gene mutating in an offspring bug.

a. True
b. False

Answers

Answer:

True

Explanation:

A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/locus/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations per round of replication, per gamete, per cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of de novo mutations per nucleotide per generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ per gene per generation.

15. What is the actual yield of the reaction if the percentage yield is 72.659

Answers

Answer:

will you msg me in I.nstagram

11. The balanced chemical reaction is:

2 B(IO₃)₃ + 3 Fe₃P → 2 BF₃ + 3 Fe(IO₃)₂

12.  In this case, the limiting reagent is the Iron (II) phosphide.

13. The amount of Iron (II) iodate produced is 1.825 moles.

14. The amount of excess Boron iodate remaining after the reaction is 0.265 moles.

15. The actual yield of the reaction is 132.1 g.

11. To write the balanced chemical reaction, we need to first determine the correct coefficients for each reactant and product. We can do this by balancing the number of atoms of each element on both sides of the equation.

12. The limiting reagent is the reactant that is used up first. In this case, the limiting reagent is the Iron (II) phosphide. This is because 112.0 g of Iron (II) phosphide is equivalent to 0.560 moles, which is less than the 1.825 moles of Boron iodate.

13. To calculate the amount of Iron (II) iodate produced, we need to multiply the number of moles of Boron iodate by the molar ratio between Boron iodate and Iron (II) iodate.

14. The amount of excess Boron iodate remaining after the reaction is 0.265 moles. This is because 1.825 moles of Boron iodate minus 0.560 moles of Iron (II) phosphide is equal to 0.265 moles.

The amount of excess Iron (II) phosphide remaining after the reaction is 56.0 g. This is because 0.560 moles of Iron (II) phosphide is equal to 56.0 g.

15. To calculate the actual yield of the reaction, we need to multiply the theoretical yield by the percentage yield.

The actual yield of the reaction is 132.1 g. This is because 1.825 moles of Boron iodate is equivalent to 132.1 g and the percentage yield is 72.659.

Two protein kinases, PK1 and PK2, work sequentially in an intracellular signaling pathway. You create cells that contain inactivating mutations in the genes that encode either PK1 or PK2 and find that these cells no longer respond to a particular extracellular signal. You also create cells containing a version of PK1 that is permanently active and find that the cells behave as though they are receiving the signal even when the signal is not present. When you introduce the permanently active version of PK1 into cells that have an inactivating mutation in PK2, you find that these cells also behave as though they are receiving the signal even when no signal is present.
Answer the following question in the space give.
A. From these results, does PK1 activate PK2, or does PK2 activate PK1? Explain your answer.

Answers

Answer:

The answer is "PK1 activates PK2"

Explanation:

All enzymes were required again for the transmission of a signal. If Pk1 is continuously active, pk2 will no longer be required, as per my theory, can trigger pk1, therefore the cells were if they amplify the message even when they're not active. But since both enzymes require regular copies together for transduction, pk2 is simple and pk1 requires to also be activated.

Answers

Answer:

All of the choices are correct

Explanation:

The respiratory syncytial virus (RSV) is an enveloped, negative-strand RNA virus (Paramyxoviridae family) capable of infecting ciliated cells of the airways by using its surface glycoproteins G and F for attachment and fusion during viral entry in target cells. RSV can affect the lungs and parts of the respiratory system (e.g., nasopharynx). Although RSV generally causes mild, cold-like symptoms, this virus may also lead to severe infection in babies (12 months) and infants, being one of the most common types of respiratory infections in children, older adults, and immunocompromised patients. Some common symptoms in individuals with RSV pneumonia include fever, nonproductive cough, dyspnea, wheezes, rales, rhonchi, etc.

From his observations in the oceanic islands like the Galapagos, Darwin felt that: isolation is a significant factor in adaptation and speciation spontaneous generation is a significant factor in adaptation and speciation volcanic soils are a significatnt factor in adaptation and speciation inheritance of acquired characteristics is a significant factor in adaptation and speciation. none of these is correct

Answers

Answer:

isolation is a significant factor in adaptation and speciation

Explanation:

In the theory of evolution by natural selection proposed by Darwin, adaptation refers to the adjustment of organisms to their environments in order to increase their chances of survival in that environment. In the Galapagos Islands, Darwin observed that finches had different types of beaks adapted to the type of food they ate. From this observation, Darwin proposed that finches evolved to eat different food sources. In this case, the islands lead to an adjustment (evolutionary) process by which geographically isolated individuals accumulate genetic differences in order to adapt them to the environmental conditions in the islands, which then may also prevent breeding between individuals from different islands when they are reunited (i.e., it may also lead to speciation).
