Many bivalves have one "foot" made of the same soft material as their bodies, and they use this to push themselves around. Some bivalves, such as scallops, can shoot water from their bodies with enough force to propel them away from any danger.
During the tetrad stage, the metaphase I of meiosis starts tohappen. When this occurs, the diploid meiocyte divides twice.
All tetrads contain four chromatids. Each "leg" is one chromatid. 2 Tetrad = 2 homologous chromosomes 1 homologous chromosome has 2 chromatids joined together by a centromere. That means that there are four chromatids in a tetrad
Was is singular and applies to one person. . Were is plural and applies to more than one person. (except in singular "you were") . eg I was ready, but you three were not ready. . "Were" is also the past subjunctive of the verb "to be" for all persons . i.e. "If I were in charge, I would fire her…." "If she were here, you would see her." "I wish I were rich." WAS is singular and WERE is plural. (MORE)
There is a big difference and they are not at all related. "are" is a verb, the present plural of the verb to be. eg We are Spanish "your " is a possessive pronoun eg This is your book; it has your name on it
their: - The possessive case of the personal pronoun they;as, their houses; their country. there: - noun : a location other than here; that place( "You can take it from there" ) - adverb : in or at that place ( "They have livedthere for years" ) - adverb : to or toward that place; awa…y from the speaker( "Go there around noon!" ) (- adverb : in that matter ( "I agree with you there" )) (MORE)
Tetrads form in Prophase 1. As the chromatin condenses, special proteins cause the homologus chromosomes to stick together in pairs. The resulting structure has 4 chromatids and is called a tetrad.
Aquatic mollusk ,like a scallop or a mussel are bivale which meananimals that consist in two hinged shells .
Both have and has are used in the Present Perfect tense of English - however, has is only used in the 3rd person singular: he/she/it has
There is no difference other then the sound and when it is used. Eg: An is used before the word which begins with a vowel an 'e'gg
THE is used when talking about a specific item for example you would say "put it on THE table" not "put it on A table" when u say THE table u mean that specific table, but if u say A table then it could mean any table available
During the metaphase I meiosis are the bivalents are arranged alongthe equator. During the prophase I of meiosis I the crossing overoccurs.
Tetrads are groups of four and can refer to genetics, generalrelativity, or chromosomal formation. A tetrad is a group of fourchromatids that are in the first stages of meiosis.
Homologous pairs are called tetrads because these pairs are maid upof a four-part structure. Tetrad literally means a group of four.
A dyad is a group of two, a tetrad is a group of four; for a group of three you can use the term triad.
Tetrads are formed of 2 homologous chromosomes, which are crossing over so there is a total of 4 chromatids. :D
listen to the song butterfly by bassnecter and you will no longer have the will to do anything but ski in white, majestic snowy, awesome, beast tron mountains.
the chromosomes form to tetrads because the cemical property with the cemical will not communtacate so you would need a genorater magnifinglass microscope 7000 . then you could see the cemiclas witch are ununununium , calcuim iron Ect. There are more than 100 cemicals in the world.
In Prophase I of meisosis. A tetrad is also called a bivalent. This happens so that crossing over can occur between non-sister chromatids. Crossing over is a source of genetic variability in the resulting daughter cells, gametes.
Homologous chromosome is when a pair of chromosomes containing the same linear gene sequences, each derived from one parent, and a tetrad is formed when 2 homologous chromosomes join together
During Prophase 1, pairs of homologous chromosomes line up to form tetrads(T) C represents a pair of centrioles that will migrate to the one end of the cell. The term tetrad refers to the four chromatids of the paired homologous chromosomes. Remember that during prophase, each chromosome has two str…ands of DNA or chromatids (MORE)
"Different from" is the correct term. "Different to" is simply acommon grammatical error. Things are "different from" or "similarto".
One pair of homologous chromosomes. One chromosome in a tetrad ispaternally inherited, while the other is maternally inherited. Eachchromosome consists of two chromatids.
ensures that the resulting haploid cells will have the same combination of homologous chromosomes as the original diploid cell
easy! has means you have something at this minute for example: he still has that dog. and have is when you have something with you for example: look what i have! or can i have that please? i hope that helped!
'These' indicates that you are reffering to something plural, e.g there is more of that thing than just 1. "Look at these apples" 'This' indicates you are refering to something singular, which means that there's only 1 of them. "Look at this apple" 'this' indicates singular while 'these'… indicates plural. (MORE)
A mega or microspore mother cell after undergoing meiosis results in to 4 haploid cells. To begin with these cells (spores) remain enclosed in the cell wall of mother cell, hence called tetrad. The spore further develops in to egg cell or male gametes and are important for sexual reproduction.
He has is referring to a boy having something at the moment, she has is referring to something a girl has at the moment, and will have is referring to something someone will have in the future.
well I am me and you are You so being me i refer to myself as I and you being yourself are not me so by definition are really an unknown tthing and therefore Alien which is something else altogether and now I, who am me are afraid of you, who are an extraterrestrail all of a sudden and could be an i…t, disquised as an I, but really a thing, an It, or even a #, a program, pretending to lead me into a maze of Identity denial. Wait who are you? Am I, you, we, They, Us, ohhhh NOOOO!!! (MORE)
Difference is used as in " There was a difference between her schedule, and mine" Different is used as is " Her schedule was different than mine" DIFFERENCE = a noun; DIFFERENT = an adjective. there's no difference its a synonym.
"Where" indicates a place, such as "Where are you?" or "That restaurant is where Timmy choked on a crab." "Were," on the other hand, has to do with something that happened in the past, such as "We were working on homework" or "Were you really choking on a crab, Timmy?" Take note that Were is to be… used with plural pronouns, like We and They. If you want to do something with a singular like I, He, etc, you'd use "was." (MORE)
During metaphase I of meiosis, tetrads line up along the equator of the cell. They are preparing for separation in the next phase.
Because of a preliminary FMD diagnosis of both 0 and Asia, an order for a bivalent vaccine was placed.
A chromatid is one half of the chromosome pair that forms in cell division. A bivalent is a cell that has four chromatids, two coming from each of two parent cells.
A tetrad is the pairing of homologous chromosomes. A human offspring inherits 23 chromosomes (N) from each parent upon fertilization, giving the offspring 46 chromosomes (2N). In meiosis, homologous chromosomes (N from mom and N from dad) come together and form a tetrad, which consists of 2 homologo…us chromosomes. Since you inherit a chromosome from both parents (2N) that pair up to form a tetrad, you will have 23 tetrads that have a chromosome from mom and dad paired together. 1 N from mom + 1 N from dad = homologous pair = 1 tetrad 2N/2 = N tetrad --humans--> 2(23 chromosomes)/2 = 23 tetrads Diploid#/2 = # tetrad (MORE)
Chromosomes come in 2 forms, depending on the stage of the cell cycle. The monad form consists of a single chromatid, a single piece of DNA containing a centromere and telomeres at the ends. The dyad form consists of 2 identical chromatids (sister chromatids) attached together at the centromere. …Chromosomes are in the dyad form before mitosis, and in the monad form after mitosis. The dyad form is the result of DNA replication: a single piece of DNA (the monad chromosome) replicated to form 2 identical DNA molecules (the 2 chromatids of the dyad chromosome). a tetrad is a pair of homologous chromosomes that have replicated and come together in prophase I of meiosis; and consists of four chromatids.

Every person is different in their own special way. None of us are the same. There is a different genetic code in every person. Also, nobody has the same finger print, not even family or twins!
To increase (gene) variation; in other words to make the chances of you looking different from someone else higher.
Into is your inside the thing. eg.He went into the house. By is like your not inside the thing but your beside it. eg. The worker rested by the tree.
Tense. "Did not" is something that didn't happen in the past, "Does not" is something that doesn't happen in the present. You must say "Napoleon Bonaparte did not live in Sweden" because Napoleon died in the 1820s; you cannot say "Napoleon Bonaparte does not live in Sweden" because he is dead and do…es not live anywhere.

on means you are on top of something, and at means you are at something... on: on top, at meaning: there. You can say: I am on the seesaw. you are riding or ontop the seesaw. I am at the seasaw: means: i am currently right there, where the seesaw is. Hoped this helped...
Tetrads don't form in mitosis. Tetrads form so that chromosomes can undergo crossing over which is a form of genetic recombination. The products of meiosis are gametes which ensure genetic diversity in subsequent generations. In mitosis, the daughter cells are genetically identical to the parent cel…l. No genetic recombination occurs in mitosis. (MORE)
During meiosis, tetrads, which are connected by a synapse partway down their length, line up along the cellular equator during metaphase I. The tetrads are then separated during anaphase I as the spindle fibers pull the tetrads apart towards opposite sides of the cell.
My thinking is ... If intrinsinc semicoductor is doped withHexavalent Impurity, then energy level of outermost orbit ofhexavalent atom, will fall below than that of pentavalent atom, somore amout of energy will be required to move this newly generatedelectron to move from fermi level to conduction b…and ofsemicondoctor. And vice versa for Bavalent. (MORE)
A and an are used when talking about something in general, while the is used when talking about a specific thing. The difference between a and an is that a is used before words with consonant sounds and an is used before words with vowel sounds.
One phrase is correct and one is not correct. no difference and not different Both phrases have the same meaning difference is a noun and different is an adjective.
No a mule is not a tetrad, this is due to the fact that the mule has 63 chromosomes. Mules are a hybrid between the horse and the donkey, and are unable to reproduce due to the uneven number of chromosomes.
The chromosomes exchange portions of their DNA, resulting in thecrossing over of genetic information. It produces gene variation insexually reproductive organisms.
The term Tetrad means a group of four. It can be used in any context when talking about something that has a collective of four such as a tetrad of cats.
