What is it called when genetic information is exchanged between homologous chromosomes during prophase 1?

A. Meiosis

B. DNA Replication

C. Crossing Over

Answers

Answer 1

Answer:

C. Crossing Over

Explanation:

Crossing over, also called recombination, is the process by which non-sister chromatids of homologous chromosomes exchange a segment of their chromosomal material with one another. The process of crossing over occurs only in the prophase I stage of meiosis.

The process is responsible for genetic variation in the gametes produced, thereby, leading to organisms that are genetically unique.

Answer 2

Answer:

C. Crossing Over

Explanation:

The crossing over is called when genetic information is exchanged between homologous chromosomes during prophase 1.

Red-green color blindness is an X-linked recessive disorder that is passed through generations and can be traced by using a pedigree.

A pedigree is shown. Sam, Bella, Joshua, and Tim have filled-in shapes. Lisa and Monica have half-filled shapes.

Which individuals in the pedigree are identified and labeled carriers for red-green color blindness?
Lisa and Monica

Answers

They all have the disease. However, carriers are generally consider those who can give the disease, but don’t have it themselves. This would make the answer Lisa and Monica as they have the recessive gene, but only have one allele, meaning they carry the gene for color blindness, but fortunately do not have it due to the dominant allele being normal.

Explain how this mutation will result in competition within the population that is linked to the idea of survival of the fittest.

Answers

Answer:

Survival of the fittest, term made famous in the fifth edition (published in 1869) of On the Origin of Species by British naturalist Charles Darwin, which suggested that organisms best adjusted to their environment are the most successful in surviving and reproducing. Darwin borrowed the term from English sociologist and philosopher Herbert Spencer, who first used it in his 1864 book Principles of Biology. (Spencer came up with the phrase only after reading Darwin’s work.)

Herbert Spencer's Principles of Biology (1864) first introduced the expression “survival of the fittest.”

Survival of the fittestQUICK FACTSKEY PEOPLEAlfred Russel WallaceHerbert SpencerRELATED TOPICSAdaptationNatural selectionDarwinian fitnessUse in evolutionary theory

Darwin did not consider the process of evolution as the survival of the fittest; he regarded it as survival of the fitter, because the “struggle for existence” (a term he took from English economist and demographer Thomas Malthus) is relative and thus not absolute. Instead, the winners with respect to species within ecosystems could become losers with a change of circumstances. For example, fossil evidence supports the notion that the mammoth (Mammuthus) was more fit during the most recent ice age (which ended roughly 11,700 years ago), but it became less fit as humans hunted it and the world’s climate warmed; fossil evidence suggests that the mammoth succumbed to extinction a few thousand years later.

Darwin’s theory of evolution by natural selection entailed three crucial elements: variation, reproduction, and heritability. Variations in the physical features of organisms that tend to benefit an individual (or a species) in the struggle for existence are preserved and passed on (or selected), because the individuals (or species) that have them tend to survive. The success or failure of a given variation is not known when it emerges; it is known only retrospectively, after organisms that possess it either grow and mature and pass it to their own offspring or fail to mature and reproduce.

Importantly, Darwin was influenced by the thinking of English physicist and mathematician Isaac Newton, whose system emphasized experimentation, mathematics, and logic over subjective sense experience. During Darwin’s time, his evolutionary theory was an attempt to construct a similar system for the living world, a frontier not yet crossed in the biological sciences.

Some philosophers and scientists have suggested that the notion of survival of the fittest is an example of circular reasoning—that is, a tautology (a statement framed in such a way that it cannot be falsified without inconsistency). In tautologies, any true statements that follow are a matter of definition. Indeed, describing those that survive as the fittest is similar to stating that those that survive survive. British philosopher Karl Popper considered “survival of the fittest” self-evident at first; however, he changed his mind after realizing that Darwin posited variation axiomatically; that is, Darwin noted that all individuals did not start with the same set of characters (or traits). Therefore, the forces affecting survival did not weigh on individuals and species equally; there were always variations, some of which would prove favourable and confer fitness over others.

Without knowing the genetic differences of the birds, how can we know that cardinals and finches are likely more closely related to each other than cardinals and finches are to woodpeckers? Cardinals and finches live in more similar habitats. There is no difference in their relatedness; because they are all birds, they all evolved at the same time from a common ancestor. Cardinals and finches have more morphological similarities. Fossil records show that cardinals have been around longer than woodpeckers and sparrows.

Answers

Answer:

The correct answer is - Cardinals and finches have more morphological similarities.

Explanation:

To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.

Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.

What does the theory of evolution contribute to conservation biology?

A) It helps scientists understand how populations and species are related, and this knowledge can be used to help these populations and species survive.

B) It helps scientists understand how populations and species are related, and this knowledge can be used to capture and breed the fittest organisms in these populations and species.

C)It helps scientists understand how populations and species react to changes in their environment, and this knowledge can be used to help these populations and species survive.

Answers

Answer: Light is necesarry for photosynthesis to occur

Explanation:

Based on the information given in the question, the investigation was most likely testing the hypothesis that light is necesarry for photosynthesis to occur.

Photosynthesis, simply means the process by which green plants transform light energy into chemical energy. It should be noted that during photosynthesis, light energy is captured which is then used in the convertion of carbon dioxide and water, into oxygen and energy which comes in form of sugar.

Answer: This investigation was most likely testing the hypothesis that SUNLIGHT is necessary for photosynthesis

Explanation:

Photosynthesis can be defined as the process by which plants (green plants) use inorganic compounds such as carbondioxide and water to manufacture their own food. This process is not only important to plants but also to animals which depends on plants for food. The main features of photosynthesis include:

--> it takes place in chlorophyll of plant cells

--> Raw materials needed for this process are inorganic compounds such as carbondioxide and water

--> Final products are organic compounds such as sugar and oxygen as by product.

--> Energy needed for this process is gotten from SUNLIGHT which is absorbed by the chlorophyll.

To show that sunlight is necessary for photosynthesis, an experiment is performed as stated in the question above. Only the part of the leaf that had NOT BEEN covered turned blue black because the exposed part has been actively photosynthesizing due to the presence of SUNLIGHT. While the covered part didn't undergo any photosynthesis as it tested negative for starch when placed in Lugol's iodine solution.
