In the photograph below, two fish are displaying a behavior commonly observed among pairs of rabbitfish. While one has its head down feeding on coral, the other remains upright, alert for predators. This behavior continues to be present in the rabbitfish population because A) this behavior was learned by observing other fish species B) both fish could not fit into the small spaces in the coral C) this behavior increases their chance of survival D) the fish species needed to become alert to survive

During inhalation, the diaphragm contracts. As it contracts, the diaphragm moves downward, increasing the volume within the thoracic cavity. Due to this increased volume in the thoracic cavity, a negative pressure gradient is generated which causes air to flow from the environment into the lungs. The lungs expand as the alveoli of the lungs fill with air.

During exhalation, the diaphragm relaxes and rises into the thoracic cavity, decreasing the volume in the thoracic cavity. The decreased volume in the thoracic cavity results in an increased pressure which causes air to flow from the lungs out to the environment. At the same time, the lungs are elastic and act to help air flow out as the retract after being expanded.

Answer:

Terrestrial ecosystems are known for their diversity; they are grouped into large categories called biomes. Grouping these ecosystems into just a few biome categories obscures the great diversity of the individual ecosystems within them. For example, there is great variation in desert vegetation: the saguaro cacti and other plant life in the Sonoran Desert, in the United States, are relatively abundant compared to the desolate rocky desert of Boa Vista, an island off the coast of Western Africa

Answer and Explanation:

We can assume that being colorblind is a recessive trait.

That means the father has a genotype of both lowercase letters, denoted as bb.

Let's make a chart.

- The Father's Genotype is bb

- The Mother's Genotype is Bb (Because she is heterozygous, which means she has one Dominant trait (B) and one recessive trait (r))

     b               b  

B|   Bb   |   Bb     |

b|   bb    |   bb     |

We get 50% of the offspring to be colorblind, and 50% of the offspring to have normal color vision.

That means the expected percentage is 50%.

Answer:

C) Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is lacking completely in cell III.

Explanation:

The  explanation that is most accurate between these two contrasting claims is that Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is completely lacking in cell III, which is in Option C.

The nucleus is present in the eukaryotic cell while it is absent in the prokaryotes, and in the nucleus are the enzymes for DNA replication, transcription, and so on that can make the DNA and the mRNA, as well as the genetic contents. The nuclear membrane acts as a barrier between the genomic contents and the cytoplasm, and transportation takes place through it.

Hence, the explanation that is most accurate between these two contrasting claims is that Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is completely lacking in cell III, which is in Option C.

Answer:

3:1, 2.95:1, 2.82:1, 2.95:1, 3.14:1 AND 1.84:1.

Explanation:

The ratio between yellow and green seed colour is 3: 1. The higher ratio of yellow colour occur because the yellow colour is dominant as compared to green seed colour.

The ratio between round and wrinkled seed shape is 2.95 : 1.

The ratio between green and yellow pod colour is 2.82 : 1.

The ratio between smooth and bumpy pod shape is 2.95 :1.

The ratio between along stem and at the tip of flower position is 3.14 : 1.

The ratio between tall and short plant height is 2.84 : 1.

A hockey puck weighing 2.0 kg has more momentum.The monentum will be larger the bigger the mass/velocity.

The relationship between momentum and an object's mass and speed is direct. Hence, an object's momentum increases with increasing mass or velocity. It is based on the speed and mass of the car. The monentum will be larger the bigger the mass/velocity.

P= East puck/mv

P = (2.0kg)(2.5m/s)

P= 5.0kgm/s

P= South puck/mv

P= (1.3kg)(3.0m/s)

P= 3.9kgm/s

Both cars will have identical momentum if they have the same mass and speed. The Momentum Calculator employs the formula p=mv, as well as momentum (p) is equivalent to the weight (m) times velocity . Any two of a values can be used by the calculator to determine the third. While lighter things have less momentum, massive ones have had more momentum for just a given speed. Because of this, stopping a loaded truck requires more effort than stopping an empty one.

Answer:

50&

Explanation:

Answer:

A.)

Explanation:

Independent assortment and crossing over is important because it creates genetic variation between gametes. This immediately eliminates (C) and in no way does crossing over or independent assortment cause more gametes to be produced so cross out (B). Only (A) and (D) is left, while both answers makes sense, (A) is the better one.

Meiosis takes place in the germ cells and give rise to haploid gametes. Due to the events including crossing over and independent assortment,  it causes genetic differences in sperm and egg, i.e., option A.

Chromosomal crossover also referred as crossing over, represents the exchange of genetic material during gamete formation,

It occurs between two non-sister chromatids of homologous chromosomes that results in recombinant chromosomes.

This creates genetic differences in the sperms and eggs.

Thus, the correct option is A.

Answer:

Genetic variation occurs because beneficial traits exist in a collection of genes, and gene flow makes these traits more prevalent in populations.

Further explanation

Genetic diversity is a level of biodiversity that refers to the total amount of genetic variation in the whole species that inhabits some or all of the earth's surface that can be inhabited.

Genetic diversity uses several simple measurements:

Gene diversity is the proportion of polymorphic loci throughout the genome.

Heterozygosity is the average number of individuals with polymorphic loci.

Alleles per locus, also used to demonstrate variability.

Explanation:

The process by which sperm are made is called spermatogenesis whereas, the process by which eggs are made is called oogenesis.

Spermatogenesis and oogenesis are the two processes involved in gametogenesis or reproductive division.

Spermatogenesis leads to the formation of male gamete called sperms, whereas oogenesis lead to the development of female gamete called ova or eggs cell.

The main difference between spermatogenesis and oogenesis is that spermatogenesis is the production process of sperms from male germ cells spermatogonia in males whereas oogenesis is the production of eggs from female germ cells oogonia in females. Diploid germ cell produces haploid gametes.

Thus, from above, it is clear that the processes by which sperms are made is called  spermatogenesis and the process by which eggs are  made is called as oogenesis.
