Answer: Epididymis

Explanation: The sperms are stored in the spiral structure of the epididymis for maturation and then released.

Sperm cells mature in the structure called the seminiferous tubules within the testes. After developing in these tubules, the sperm move to the epididymis where they continue to mature and then during ejaculation, they exit the body via the vas deferens. This highlights the different stages of sperm development and maturity in the male reproductive system.

Sperm cells develop to maturity in a structure called the seminiferous tubules, which are coiled inside the testes. The least developed sperm are located at the periphery of the tubule, while the fully developed sperm are in the lumen. Within the walls of these tubules, the sperm cells are mixed with Sertoli cells, also referred to as 'nursemaid cells', which protect the germ cells and support their development.

Once the sperm cells have developed, they exit the seminiferous tubules and move to the epididymis where they continue their maturation process. The epididymis is a coiled tube located on the top and posterior of the testes. Upon ejaculation, the mature sperm leave the epididymis, travel through the vas deferens, and form the ejaculatory duct.

Water breathing animals do not face a challenge for respiration in water because they have evolved ways to optimize oxygen uptake from the water they inhabit.

These animals have adapted specialized gills that contain a large surface area which enables them to efficiently absorb oxygen from the water. They also have an increased number of blood vessels in their gills which increases the oxygen uptake from the surrounding water.

Additionally, the blood vessels in their gills contain counter current exchange systems that enable them to extract more oxygen from the water. This adaptation allows these animals to extract more oxygen from the water than would otherwise be available in the surrounding environment.

True. The erectile tissue which forms the corpus spongiosum is a continuation of the erectile tissue of the crus.

The corpus spongiosum is a column of erectile tissue that is part of the male anatomy. It is located in the center of the male reproductive organ and runs along the length of the shaft. The corpus spongiosum is surrounded by two other columns of erectile tissue, known as the corpora cavernosa, which are responsible for the majority of the male reproductive organ' girth and length. The corpus spongiosum is unique in that it surrounds the urethra and expands at the end to form the front rounded pat of male reproductive organ. The corpus spongiosum also plays a role in the process of erection by filling with blood during sexual arousal, causing the male reproductive organ to become engorged and stiff.

Sensory neurons, interneurons, and motor neurons are three types of neurons that make up the nervous system.

Sensory neurons: Sensory neurons are responsible for detecting stimuli, such as light, sound, touch, or temperature, and transmitting this information from sensory receptors to the central nervous system (CNS).

These neurons have specialized receptors on their dendrites that respond to specific types of stimuli. For example, photoreceptor cells in the eye respond to light, while mechanoreceptor cells in the skin respond to touch and pressure.

Interneurons: Interneurons are located within the CNS and are responsible for processing and integrating information received from sensory neurons. They receive signals from sensory neurons and other interneurons, and then transmit this information to motor neurons or other interneurons.

Interneurons play a key role in the complex processing of information that occurs within the CNS, including memory, learning, and decision-making.

Motor neurons: Motor neurons are responsible for transmitting signals from the CNS to muscles or glands, resulting in movement or secretion. They receive input from sensory neurons and interneurons and then produce a response, such as contracting a muscle or secreting a hormone.

Motor neurons are classified into two types: somatic motor neurons, which control skeletal muscle movements, and autonomic motor neurons, which control involuntary responses, such as heart rate and digestion.

Answer:

evolution of bacterial genomes.

Explanation:

Conjugation plays an important role in evolution of evolution of bacterial genomes.Human pathogenic bacteria may have acquired many of the virulent traits, as well as antibiotic resistance by conjugation.

During DNA replication (S phase), the chromosomes are duplicated, resulting in 16 sister chromatids. During metaphase, the sister chromatids align along the equatorial plane of the cell. During anaphase, the sister chromatids separate and move towards opposite poles of the cell, ensuring that each new cell receives a complete set of 8 chromosomes.

During mitosis, the process by which cells divide, the division of chromosomes occurs in a way that maintains the correct number of chromosomes in each resulting cell. The scenario you mentioned, where one cell with 8 chromosomes divides to form two cells each with 8 chromosomes, is possible due to three key events and their associated cell cycle phases:

DNA Replication (S Phase): Before mitosis begins, the DNA in the cell undergoes replication during the S phase of the cell cycle. This means that each chromosome replicates, resulting in two identical copies called sister chromatids. So, in the initial cell with 8 chromosomes, during S phase, each chromosome is duplicated, resulting in a total of 16 chromatids.

Chromosome Alignment and Separation (Metaphase and Anaphase): During metaphase, the replicated chromosomes align along the equatorial plane of the cell. The sister chromatids are connected at a region called the centromere. In anaphase, the centromeres split, and the sister chromatids separate, becoming individual chromosomes. The spindle fibers pull the separated chromosomes towards opposite poles of the cell.

Cytokinesis: After the chromosomes have separated, cytokinesis occurs, where the cell membrane pinches inward, dividing the cytoplasm into two distinct cells. Each new cell receives a set of chromosomes, resulting in two daughter cells, each with the same number of chromosomes as the original cell (8 chromosomes each).

Overall, through the processes of DNA replication, chromosome alignment and separation, and cytokinesis, the division of chromosomes during mitosis ensures that the resulting daughter cells maintain the correct number of chromosomes.

Answer:

The whole progeny will be not-blinded. All the individuals in the F1 will be able to see.          

Explanation:  

Multiple genes can affect the same trait. Two blind fishes can produce not-blinded offspring because parents have mutations in two different genes. This is a case of complementation. When parents have a mutation in the same gene, this process is known as non-complementation, and in these cases, their progeny will exhibit the mutated trait.

We know that blindness is a trait controlled by multiple genes and inherited in a recessive manner. So we need at least two genes to have not-blinded eyes, and in the exposed example the mutation that causes blindness is in fact in two different genes.

So let´s say that genes B and E are two genes involved in eye formation and that their respective recessive alleles will express blindness. Then:

Cross: A blind fish from a true-breeding line in B gene crossed to a blind fish from a true-breeding line in E gene.

Parental) BB ee   x   bb EE

Gametes) Be   Be   Be   Be

                 bE   bE   bE  bE

Punnet square)    Be      Be      Be      Be

                   bE   BbEe  BbEe  BbEe  BbEe

                   bE   BbEe  BbEe  BbEe  BbEe

                   bE   BbEe  BbEe  BbEe  BbEe

                   bE   BbEe  BbEe  BbEe  BbEe

F1) 100 %  BbEe, heterozygote for both genes. None of the F1 individuals are blind.                

If the mutation that causes blindness is in two different genes in the two fish, it is expected that NONE of the offspring are blind.

In conclusion, if the mutation that causes blindness is in two different genes in the two fish, it is expected that NONE of the offspring are blind.

Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. They recorded substrate color, and coat-color frequencies for each location. Each site was separated from any of the others by at least eight kilometers. The researchers trapped a total of 275 mice. Their data are summarized below (numbers have been slightly modified for the purposes of this worksheet).

Field Data Summary

Collecting Site Substrate Color Number of Mice Phenotype Light Dark

1 Dark 22 3 19

2 Light 80 74 6

3 Light 22 19 3

4 Dark 28 3 25

5 Light 58 25 33

6 Dark 65 9 56

2. Calculate the overall frequencies of light-colored mice and dark-colored mice caught on dark-colored substrates. (to 3 decimal places)

3. Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the light, rocky, granite substrate. For genotype frequencies use three decimal places and for calculations using the allele frequencies, you must round the allele frequencies to two decimal places.

4. Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the three genotypes on the dark, rocky lava substrate. (to 3 decimals). For genotype frequencies use three decimal places and for calculations using the allele frequencies, you must round the allele frequencies to two decimal places.

5. Which fur color seems to have the greatest overall selective advantage? Use data collected from both dark-colored and light- colored substrates to support your answer.

6.What environmental change gave a selective advantage for one coat color over another?

7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?

8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.

Answer:

1)

2)

3)

4)

5) The dark-colored fur seems to have the greatest overall selective advantage

6) Dark lava changed the color of the substrate, from light to dark.

7) Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color.
