The breeding of organisms over many generations in order to achieve a desirable phenotype?
Answer:
Selective breeding involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. Humans have selectively bred plants and animals for thousands of years including: crop plants with better yields.

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
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).

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 :)
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.

In ecosystems, plants transform light energy from the Sun into chemical energy when they make sugar. This sugar can then be consumed by other organisms to be used as building blocks for other molecules, such as proteins and fats, or it can be transformed into other forms of energy, such as kinetic energy, when the organism moves. Which of the following statements is supported by the above information? A. Energy can change forms, but only one kind of matter exists. B. Matter can change forms, but only one kind of energy exists. C. Matter and energy can change forms and locations in ecosystems. D. Matter and energy must always remain in the same form and location.

In Drosophila, the linked mutations ebony body color (e), rough eyes (r), and brevis bristles (b), are autosomal recessive. A test cross yielded the following results:
wild type 169
ebony 619
ebony, rough 9
brevis 14
rough 93
ebony, brevis 97
rough, brevis 621
ebony, rough, brevis 165
Total 1787
1: Which locus is in somewhere between the other two?
a. ebony
b. rough
c. brevis
d. wild type
e. can not be determined from the information provided
2: What is the percentage of double cross overs?
Answer:
The correct answer is - 1) rough
2) [(9+14)/1786]* 100 = 1.2877 percentage
Explanation:
In this case there is mutated genes are :
mutated : ebony (e), rough (r) and brevis (b)
wild type: e+, r+ and b+
Given: wild type 169 (e+ r+ b+)
ebony 619 (e b+ r+)....... parent
rough, brevis 621 (e+ b r) .... parent
ebony, rough, brevis - 165 (e r b)
rough - 93 (e+ r b+)
ebony, brevis - 97 (e r+ b)
ebony, rough - 9 (e r b+) ....... double cross
brevis - 14 (e+ r+ b) ..... double cross
solution:
In this question, there is the three-point cross is performed, in such case, if one is mutated then the other two are normal. For instance, here ebony is mutated then the rest two are norma - e r+ b+.
We know the most frequent genotypes in such case, are parental and least frequent are double crossover genotypes. We can get the correct order of genes by the double-cross of parental genotypes and if we get double cross over then the gene order is correct.
(e b+ r+) -----------> (e r b+)
(e+ b r) ------------> (e+ r+ b)
double cross double crossover
between
parental gentype
Thus, the correct order is e r b that means rough is between ebony and brevis.
The percentage of double cross over =
(number of first double-cross + second double-cross over/1787)*100
[(9+14)/1786]* 100 = 1.2877 percentage

The Pine Tree shown below is a common gymnosperm. Name three adaptations this tree has that allow it to live on land
A waxy cuticle that covers the outer surface of the plant and prevents drying out through evaporation. The cuticle also partially protects against radiation damage from UV light.
Stomata (singular: stoma) are present in all land plant lineages except liverworts (similar to -but not the same as! – mosses). Stomata are pores or holes which allow for exchange of gasses (such as oxygen and carbon dioxide) between the plant cells and the environment. Stomata or similar structures are necessary in land plants because the waxy cuticle blocks free-flow of gasses.
Roots (or root-like structures) anchor plants to the soil and—in plants with true roots— serve as conduits for water absorption. All land plants except Bryophytes (mosses, liverworts, and hornworts) have true roots. Bryophytes have root-like structures called rhizoids that anchor them to their substrate but are not involved in water absorption (which is less important for Bryophytes because they can only survive in very moist environments).
Mutualistic association with mycorrhizal fungi, which are tightly associated with plant roots. Mychorrhizal fungi are associated with approximately 80% of all land plant species and provide additional surface area for absorption of both water and nutrients from the soil. The fungi share these resources with the plant roots, and—in exchange— the plant shares photosynthetic sugar products with the fungi.
The alternation of generations life cycle, which includes both a multicellular haploid stage and a multicellular diploid stage. Why is this an adaptation to life on land? It isn’t, in and of itself—in fact, it also occurs in *some* green algae, which are aquatic but share a common ancestor with all land plants. But specific adaptations to the alternation of generations life cycle have occurred in different lineages of plants, and those adaptations DO function as adaptations to life on land. We’ll consider these adaptations later in this reading.
These are from my text book, from last year.
Answer:
It has cuticle, a waxy, airtight seal that covers plants and allows them to retain water.
It has seeds, plant embryos without a protective cover on the scales of a cone which allows them to disperse into new locations.
It has pollen, but it is not produced in flowers, which allows it to reproduce without the need of water.

Minerals are needed for the proper composition of body fluids, including blood, and for the proper composition of tissues, bone, teeth, muscles and nerves. Minerals also play a significant role in maintaining healthy nerve function, the regulation of muscle tone, and supporting a healthy cardiovascular system. There are two kinds of minerals: macrominerals and trace minerals.
