Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the male minnows all had a moderate number of spots.
Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female minnows in this pond preferred to mate with males that had the most spots.
After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Fish Species Average # of Spots
Original Species four to six
New Species 1 zero to two
New Species 2 eight to ten
Which of the following best describes why the two minnow populations evolved into separate species?
A.
Natural selection acted upon the traits of the minnows in the first pond only, causing these fish to evolve into a new species with new adaptations.
B.
Natural selection acted upon the traits of the minnows in the second pond only, causing these fish to evolve into a new species with new adaptations.
C.
The same selective pressures were acting upon both populations, leading to a decrease in genetic variation and the formation of two new species.
D.
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.

The structural and functional units of the kidney are called
Answers
Answer:
The structural and functional units of the kidney are called nephron.
Fun Facts about Nephron:
Nephron is the structural and functional unit of the kidney.
Its primary purpose is to maintain the concentration of water and soluble chemicals such as sodium salts in the blood by filtering it, reabsorbing what is needed, and excreting the excess as urine.
The glomerulus and renal (kidney) tubule are the two primary structures in each nephron. Each human kidney contains around 1,000,000 nephrons.
The structural and functional units of the kidney are called the nephrons. Each human kidney contains 8-10 lakhs nephrons.
What do you mean by Kidney?A Kidney may be defined as a pair of bean-shaped organs that eliminate waste and extra water from the blood and help keep chemicals balanced in the body.
Each nephron contains two structures i.e. Glomerulus and Tubules. The Glomerulus is a tough capillary through which a large amount of fluid is filtered from the blood.
Tubules are the other structure of the nephron in which the filtered fluid is converted into the urine.
Therefore, the structural and functional units of the kidney are called nephrons.

Which repair process in e. Coli uses visible light to repair thymine dimers?.
Answers
Answer:
photoreactivation repair
Explanation:
Photoreactivation utilizes the enzyme photolyase to break the bonds formed during pyrimidine dimerization. A thymine dimer produced by UV irradiation is bound by photolyase. Visible light energy is absorbed by photolyase and is redirected to break the bonds forming the dimer.
In addition to bacteria, this DNA repair mechanism is also found in single-celled eukaryotes, plants, and some animals such as Drosophila.

Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Answers
Answer: This shows that over time, some insects can become "pesticide-resistant" meaning that pesticides don't affect them anymore. And this only happens every few generations. Therefore, each generation is being naturally selected and accumulating variations that make them resist the chemicals. This shows that each cockroach's genes are changing to give them variation from the rest of the population.

please what is meant by photosynthesis
Answers
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water, In most cases, oxygen is also released as a waste product that stores three times more chemical energy than the carbohydrates. Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

Answers
Offspring whose genotype is either BB or Bb will have the dominant trait expressed phenotypically,
The dominant characteristic will be phenotypically manifested in offspring whose genotype could be BB or Bb.
What is genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual possesses in a certain gene or genetic region are also referred to as the genotype.
The amount of copies of the each chromosome contained in that species, commonly known as ploidy, determines how many alleles a person can have for a certain gene. In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person possesses two alleles for each gene. The dominant characteristic will be phenotypically manifested in offspring whose genotype could be BB or Bb.
Therefore, the dominant characteristic will be phenotypically manifested in offspring whose genotype could be BB or Bb.
