Answer: D
Explanation:
Use Darwin’s finches as example they were separated and speciation occurred in the changed beaks
In which situation is speciation MOST likely to occur is few members of the population are isolated from the others.
What can cause speciation?The speciation process usually occurs due to adverse conditions imposed by the environment. Briefly, two causes are attributed for the process to occur: Geographical Isolation: When lineages of a species separate from the rest of the species for environmental reasons.
In this case, a species no longer identifies with it and thus it isolates itself from its environment.

Help please!!!!!!!!!!!!!!!!
Answer:
D is NOT true about plants.
In your own words describe how genetic diversity is increased through the processes of crossing over, independent assortment, and random sexual reproduction.
Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.

Explanation:
Don came up with the hypotheses that butterflies prefer to eat nectar from white flowers Don conduct an experiment and learn that his hypotheses with not correct what should Don do next
Answer:
B
Explanation:
A. Don should change the data he collected to make it look like the hypothesis was correct.
B. Don should test a new hypothesis.
C. Don should communicate the results of his experiment.
D. Don should hide his results so that nobody can see that he was wrong.
The correct thing for Don to do would be to test another hypothesis.
Hypotheses are generalized statements without any experimental tests. Once they are tested and are found not to be true, the next thing is to discard them.
A hypothesis that has been proven not to be true no longer serves any purpose. The next thing would be for Don to make and test a new one.
The correct option is B.
Answer:
Don should communicate the results of his experiment.

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose
A) atp is used
B) pyruvic acid is produced
C) oxygen is produced
D) nadph is made
Answer:
D)NADPH is made
A)ATP is used
Explanation:
Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]
The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:
Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.
First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).
Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis). That is, the chemical energy of ATP and the reducing potential of NADPH, both produced with the use of light energy, keep the Calvin cycle running. Conversely, the Calvin cycle regenerates ADP and NADP^+

The structure labeled "A" open and close the sites where the gases, carbon dioxide and oxygen, are exchanged during photosynthesis. What is the structure labeled A?
The structure A in the question seems missing but the given answer is based on the description given in the question.
Answer:
The gaseous exchange of carbon dioxide(CO2) and oxygen(O2) occurs through small, regulated openings called stomata during photosynthesis.
Therefore the Structure A is Stomata

Answer:
true
they get equal chromosome from each parent.
Answer: False
Explanation:
While women do inherit 50% of their DNA from each parent, men inherit about 51% from their mother and only 49% from their father. ... To answer this question, first a little 101 in genetics: all humans, both male and female, inherit 23 chromosome pairs from their parents, for a total of 46 chromosomes
Use the diagram to answer the question. Between which parts of the molecule must the bonds be broken to form an ADP molecule?
The parts of the molecule whose bond must be broken to form an ADP molecule would be between C and D. Thus, option A would be correct.
The image is an illustration of the structure of ATP, Adenosine Triphosphate. The hydrolysis of the terminal phosphoanhydridic bond in ATP yields energy for metabolic reactions in biological systems and ADP (Adenosine Diphosphate) is formed as a result.
In this case, the terminal phosphoanhydridic is D. Thus, the bond between D and C must be broken for ADP to result.

A couple has two children, one with brown hair and blue eyes and one with brown hair and brown eyes. The fact that the children can have the same hair color but different eye color is explained by the Group of answer choices principle of dominance. law of independent assortment. law of segregation. principle of probability.
The fact that the children can have the same hair color but different eye colors can be explained by the LAW of independent assortment.
The law of independent assortment states that non-linked genes and chromosomes segregate (separate) in an independent manner during Meiosis. The independent assortment of chromosomes generates genetic variation by increasing the possible combinations of genes in offspring.The law of independent assortment was first observed by Gregor Mendel in 1865 during his experiment using pea plants.In conclusion, the fact that the children can have the same hair color but different eye colors can be explained by the LAW of independent assortment.
