Answer:
Option B.

Explanation:

Why?

A is incorrect
Large tsunami tides are not made by ocean currents. The wind has little to no effect in a tsunami. Like making waves in a pool of water, there is a required disturbance that causes the water to move.  

C is incorrect.
It has to do with disturbances but its not quite the response were looking for.

D is incorrect.
Option D is describing a flood. in large bodies of water like a big lake or pond, you'll find that to be the case.

Tsunamis are created by a disturbance in the ocean floor. Much like earthquakes, the ocean experiences new plate formation and movement.

A baseline concussion test is often performed using a computer for evaluating a player whether someone is concussed.

Testing for concussions measures your brain's recovery from a head injury. Questionnaires or symptom checklists are the main components of most concussion assessments. Concussion exams evaluate your mental agility, memory, focus, awareness, and ability to solve tasks. Your coordination and balance are also tested. One of the methods used to identify a concussion is concussion testing. Concussion tests are used by medical professionals, athletic trainers, and coaches to assess brain function before and after a head injury.

Thus from above conclusion we can say that a baseline concussion test is often performed using a computer for evaluating a player whether someone is concussed.

Answer:

The fourth and final phase of mitosis or meiosis is called telophase. During telophase, the nuclear membrane forms around the chromosomes on opposite sides of the cell, and the chromosomes become unwound DNA in newly formed nuclei.

In mitosis, telophase is the final phase of the cell cycle, during which the cell's genetic material is divided into two new daughter cells. In meiosis, telophase is the final phase of the meiotic cell division, during which the genetic material is divided into four new daughter cells, each with half the number of chromosomes as the original cell.

During telophase, the cell also begins to rearrange its cytoskeleton and reorganize its cytoplasm in preparation for cell division. This allows the two new daughter cells to separate and become independent organisms.

The telophase is the fourth and final phase of mitosis or meiosis, when a nuclear membrane forms around chromosomes on opposite sides of the cell and the chromosomes become unwound DNA in a newly formed nucleus.

It is the final stage of cell division, in which the cell is about to divide into two different cells in mitosis, and there are four cells meiosis, and in telophase, the genetic contents are present at opposite poles and the DNA is decondensed. In all the phases of the cell cycle, the telophase is the last one where cytokinesis begins.

Hence, the telophase is the fourth and final phase of mitosis or meiosis, when a nuclear membrane forms around chromosomes on opposite sides of the cell and the chromosomes become unwound DNA in a newly formed nucleus.

The phylum Chordata or subphylum vertebrata is made up of bilaterally symmetrical adult animals with ecto, meso, and endoderm derived tissues and a notochord.

what are chordates?

The phylum Chordata and the kingdom Animalia both have vertebrates as members. The four distinguishing characteristics of animals in the phylum Chordata are a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a postanal tail. These characteristics all arise at some point throughout animal development. Some of these are only present during embryonic development in certain groups.

Additionally, chordates have a segmented body, triploblastic, bilaterally symmetrical, and coelomic skeleton.

The body design is intricate and distinctive.

Organ systems are the level of organization found in the body.

The notochord, a flexible, rod-shaped structure present in all chordate embryos and in the adult stages of some chordate species, is the source of the name "Chordate," which refers to a group of organisms. It supports the skeleton along the entire length of the body and is situated between the digestive tract and the spinal cord.

The class Vertebrata includes all vertebrates. Vertebrates have all four of the chordates' defining qualities, but they also have derived traits that set them apart from invertebrate chordates. Vertebrata gets its name from the vertebral column, which is made up of distinct bones called vertebrae that are linked together to form the backbone. The notochord, which is only present in the embryonic stage, is replaced by the vertebral column in adult vertebrates.

When different species evolve a similar, or even the same, solution to life in similar environments and evolve their solution even though they did not have a recent common ancestor with that solution it is called convergent evolution.

When a group within a species separates from other members of its species and develops its own distinct characteristics, this is referred to as speciation. Convergent evolution refers to the independent evolution of similar characteristics in species from different time periods or epochs. Convergent evolution produces analogous structures that have similar form or function but weren't present in those groups' last common ancestor.  Homoplasy is the cladistic term for the identical phenomenon.

Flight is a classic example of recurrent evolution, as flying insects, birds, pterosaurs, but also bats have all independently evolved the useful ability to fly. Analogous features are functionally similar features that have evolved through convergent evolution, whereas homologous structures as well as traits have a common origin but may perform dissimilar functions.

Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.

Explanation:These cells are different because they use the same set of genes differently. So even though each of our cells has the same 20,000 or so genes, each cell can select which ones it wants to “turn on” and which ones it wants to keep “turned off”.

Answer:

A. hidden

Explanation:

Many desert plants use allelopathy to minimize competition and to keep other organisms away. This causes a hidden dispersal pattern among the plants, in which they are spaced out and not evenly distributed. Allelopathy is the production of chemical compounds by plants that are toxic or inhibitory to other organisms. These compounds can be released into the soil, where they can affect the growth and survival of other plants. By using allelopathy, desert plants can reduce competition for resources and increase their chances of survival in the harsh desert environment.

Passive transport is the movement of molecules across the cell membrane without the need for the input of cellular energy. This statement is true.

Plasma membranes allow special substances to enter and exit the cell, preventing harmful material from entering and essential material from leaving. Plasma membranes are selectively permeable allowing some substances through while restricting others. If they give up this selectivity, the cell will be unable to fortify itself, and will be wiped out.

Most direct forms of membrane transport are passive. Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy in order to carry out the movement.

Passive transport relies on the second law of thermodynamics instead of using cellular energy such as active transport which drive the movement of substances across cell membranes.

Bears play the role of consumer in a forest ecosystem.

Explanation:

Bears are omnivores, meaning they get their energy from both producers and other consumers.

Bears are another example of consumers. Black bears are omnivores and scavengers, like skunks and raccoons, which means that they will eat just about anything. In a forest community, black bears will eat blueberries, bugs, acorns, and many kinds of nuts.

The bear is a primary consumer as it directly feeds on plants, berries in this case. The bear, when eats rodents, becomes a secondary consumer. Rodents feed on grass, so is a primary consumer.

Bears play the role of consumer in a forest ecosystem.

Consumers are living things that must seek, gather, and consume their food. Customers must eat to refuel or they will perish. Omnivores, carnivores, herbivores, and decomposers are the four different categories of consumers.

Zooplankton, butterflies, rabbits, giraffes, pandas, and elephants are a few examples of primary consumers. Herbivores are the main consumers. Their primary food source is either plants or creatures at the first trophic level of the food chain. Autotrophs are another name for plants.

Codons are three letter genetic words: and the language of genes use 4 letters (=nitrogenous bases). Hence 64 words are there in genetic dictionary, to represent 20 amino acids that the biological organisms use.

And you must note that more than one codon may code for the same amino acid. This is referred to as degeneracy of the code. For example, three amino acids are coded by any of six different codons, and that alone uses up 18 of the 64 combinations. Three of the codons are stop codons. They do not code for any amino acid. Instead, they act as signals to end the genetic message carried by messenger RNA.

A stop codon is a trinucleotide sequence of three nucleotides found in messenger RNA (mRNA) or DNA that instructs the cell to stop production of proteins. There are 64 distinct trinucleotide codons, of which 3 are stop codons and 61 define amino acids (i.e., UAA, UAG and UGA). A stop codon (or termination codon) is a codon (nucleotide triplet within messenger RNA) that marks the end of the current protein's translation process in molecular biology, more specifically in protein biosynthesis.

The number of amino acids coded by codons is

1 codons ×2 amino acids = 2 codons

2 codons ×9 amino acids = 18 codons

3 codons ×1 amino acid = 3 codons

4 codons ×5 amino acids = 20 codons
