Which answer best explains the difference between protists and bacteria?

A. Bacteria are prokaryotes and protists are eukaryotes

B. Bacteria have a cell membrane while protists do not

C. Bacteria have ribosomes while protists do not

D: bacteria have cytoplasm while protists do not

Answers

Answer:

The correct option is A. Bacteria are prokaryotes and protists are eukaryotes

Explanation:

The major difference between BACTERIA AND PROTISTS is the Bacteria are PROKARYOTES in nature and they dont have what we called nucleus reason been that their microbes are single celled microbes while protists on the other hand are EUKARYOTIC in nature and they have nucleus and they can either have a single-celled or have more than one celled.

The Second difference is that protists can only be found in the area or surrounding that are mostly moisture while bacterial on the second hand can be found in every area, environment or surrounding.

Therefore the answer that best explains the difference between both protists and bacteria

Is option A which states that Bacteria are PROKARYOTES while protists are EUKARYOTES.

If the DNA code reads CCAATTGG then the tRNA code would read?

Answers

Answer:

CCAAUUGG

Explanation:

A tRNA is all the letters stay the same unless there is a T or a U. a T turns into a U and vise versa.

In case DNA code offers the reading CCAATTGG, the reading of the code tRNA would be:

CCAAUUGG

The term "tRNA or Transfer RNA" is described as the small atoms that may function for the purpose of carrying/transferring amino acids.In the given situation, "tRNA" code for the provided DNA code reading would be similar to the DNA except for T. The letter "T" would be replaced with U in tRNA and U become T while converting it to DNA.

Thus, "CCAAUUGG" is the correct answer.

Work is the transfer of energy , Energy is the capacity for doing work , and Power is work being done in a unit of time.

There are 2 types of energy

Kinetic Energy : Energy of Motion

Potential Energy : Stored Energy

When calculating work energy and power you use WORK = W=Fd

Because energy is the capacity to do work , we measure energy and work in the same units. Power's SI unit of measurement is the Watt, representing the generation or absorption of energy at the rate of 1 Joule/sec. Power's unit of measurement in the English system is the horsepower, which is equivalent to 735.7 Watts.

Answers

Complete question:

Suppose a graduate student is studying a loss-of-function mutation in the mouse gene zigzag. Whereas wild type mice have straight tails, zigzag mutant mice have tails with two sharp kinks, so that the tail looks like the letter Z. To determine how the zigzag phenotype is inherited, he performs the crosses listed in the first column of the table below, using parents from true-breeding lines. Three possible sets of results from these crosses are shown. Determine the mode of inheritance of the zigzag gene that would yield each result set.

Mode of inheritance Options:

cytoplasmic-linked recessive inheritance,  maternal effect inheritance, genomic imprinting (paternal allele is inactive), genomic imprinting (maternal allele is inactive), x-linked recessive inheritance

Note: You will find the table in the attached file

Answer:

Set A: X-linked recessive inheritanceSet B: maternal effect inheritanceSet C: genomic imprint (paternal allele is inactive)

Explanation:

SET A:

X-linked recessive inheritance: This pattern refers to a recessive mutated allele that expresses the abnormal character and is linked to the X chromosome.  

Cross 1: zig zag female   x   wild type male

Parental) Xz Xz     x    X+Y

F1) Phenotype---> 50% zigzag (all males)   ;  50% wild type (all females)    

      Genotype---> ½ X+ Xz   ;   ½ Xz Y      

Cross 2:  

Parental) X+ Xz     x   Xz Y    

F1) Phenotype---> From the whole progeny: 25% wild type females ; 25% wild type males ; 25% zigzag females ; 25% zigzag males - 50% wild type animals + 50% zigzag animals

     Genotype---> ¼ Xx Xz  ; ¼  Xx Y ;   ¼ Xz Xz  ; ¼  Xz Y      

Cross 3: wild type female   x   zigzag male

Parental) X+ X+     x    XzY

F1) Phenotype---> 100% wild type animals (50% females + 50% males)

      Genotype --->  ½ X+ Xz   ;   ½ X+ Y      

Cross 4:

Parentals) X+ Xz     x    X+Y

F1) Phenotype---> From the whole progeny: 50% wild type females ;  25% wild type males ; 25% zigzag males

      Genotype --->  ¼ X+ X+ ; ¼  X+ Xz   ;  ¼ X+ Y  ;  ¼  Xz  Y

SET B:

Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. The progeny genotype is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. This effect is commonly seen in insects, but it might also occur in mammals and plants. A much known experiment about this effect is the one performed on Limnea sp snail.  

Cross 1: zig zag female   x   wild type male

Parental) Xz Xz     x    X+Y

F1) Phenotype-->100% zigzag animals, due to the female´s phenotype, Xz Xz      

      Genotype--> ½ X+ Xz   ;   ½ Xz Y      

Cross 2:  

Parental) Xx Xz     x   Xz Y    

F1) Phenotype-->100% wild type animals, due to the female´s phenotype, Xx Xz      

     Genotype--> ¼ Xx Xz  ; ¼  Xx Y ;   ¼ Xz Xz  ; ¼  Xz Y      

Cross 3: wild type female   x   zigzag male

Parental) X+ X+     x    XzY

F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+X+      

      Genotype --> ½ X+ Xz   ;   ½ X+ Y      

Cross 4:

Parentals) X+ Xz     x    X+Y

F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+ Xz      

      Genotype---> 100% wild type animals      

SET C:

Genomic imprint (Paternal allele inactive): Refers to a pattern that characterizes for epigenetically inheritance and for unequally functional paternal and maternal genomes. Males X chromosomes are inactive or imprinted and have a different function from those females X chromosomes. This is a common pattern in some mammals, insects and angiosperms. The paternal allele can not be expressed which causes an unequal contribution to the progeny phenotype.  

Cross 1: zig zag female   x   wild type male

Parental) Xz Xz     x    X+Y

F1) Phenotype--->100% zigzag animals, because the male´s X chromosome is imprinted or inactive      

      Genotype--->½ X+ Xz   ;   ½ Xz Y      

Cross 2:  

Parental) Xx Xz     x   Xz Y    

F1) Phenotype--->50% wild type animals ; 50% zigzag animals.  Due to both the female´s chromosomes, Xx Xz      

     Genotype---> ¼ Xx Xz  ; ¼  Xx Y ;   ¼ Xz Xz  ; ¼  Xz Y      

Cross 3: wild type female   x   zigzag male

Parental) X+ X+     x    XzY

F1) Phenotype--->100% wild type animals, due to the female´s phenotype, X+X+      

      Genotype ---> ½ X+ Xz   ;   ½ X+ Y      

Cross 4:

Parentals) X+ Xz     x    X+Y

F1) Phenotype--->50% wild type animals ; 50% zigzag animals

      Genotype ---> ¼ X+ X+ ;  X+ Y  (Wild type)  

                            ¼  X+ Xz   ;  ¼ Xz Y  ( zigzag)

If convection cells in the asthenosphere are the mechanism behind plate tectonic movement, what powers the convection cells?

a) energy from the sun
b) energy from the earth's core
c) air pressure changes
d) energy from magma

Answers

I think the answer will be C

The energy that powers the convection cells is ENERGY from the earth's core (Option B).

Convection currents, also known as convection cells, are caused by density differences within a body of liquid or gas.

Convection cells inside of the Earth form as material near the Earth's core heats up.

The asthenosphere refers to the upper mantle layer beneath the lithospheric mantle which is involved in plate tectonic movement.

The heat inside the Earth's core heats the asthenosphere, which is associated with the movement or 'motion' of convection cells.

In conclusion, the energy that powers the convection cells is ENERGY from the earth's core (Option B is correct).

Answers

Answer:

antibodies - proteins (gamma globulins)

Explanation:

The ribosome, a biological component found in the cytoplasm of cells, is in charge of producing luciferase.

what is  cytoplasm:

The ribosomes are responsible for producing all proteins.The cytoplasm of a cell contains ribosomes, which are cell organelles that allow mRNA and tRNA to function so that proteins can be produced.All of the components of a eukaryotic cell outside of the cell nucleus are referred to as cytoplasm in cell biology. Nucleoplasm is the name for the substance that makes up the nucleus and is enclosed within the nuclear membrane. The cytosol, a gel-like fluid, the organelles, and numerous cytoplasmic inclusions are the three primary elements of the cytoplasm. About 80% of the cytoplasm contains water, and it is typically colorless.After removing the cell organelles and particles, groundplasm—a submicroscopic ground cell material or cytoplasmic matrix—remains. The bigger organelles, including ribosomes, mitochondria, plant plastids, lipid droplets, and vacuoles, are suspended in this highly intricate, polyphasic structure known as the hyaloplasm of light microscopy.The majority of cellular functions, including several metabolic pathways, including glycolysis, and procedures like cell division, take place within the cytoplasm. The concentrated inner region is known as the endoplasm, and the cell cortex or ectoplasm is the name of the outside layer.

This is so that codons can be inserted, amino acids can be formed, and all the proteins, including luciferase, can be formed. The ribosome traps the mRNA molecule and moves over it.

how does coriolis effect affect the climate zones in the world? PLEASE HELP! I WILL GIVE BRAINLY TO PROPER ANSWER!

Answers

Answer:

Please Mark as Brainliest

Explanation:

The development of weather patterns, such as cyclones and trade winds, are examples of the impact of the Coriolis effect. ... As warm air rises near the Equator, for instance, it flows toward the poles. In the Northern Hemisphere, these warm air currents are deflected to the right (east) as they move northward.

The Coriolis effect was presumed to be the reason for the rotation of low pressure areas which is anticlockwise in the Northern Hemisphere and Clockwise in the Southern Hemisphere. The problem with this is that it would carry the winds to the east in either hemisphere because of the velocity of the surface being faster near the equator going east bound at the equator at just over 1,000 miles per hour. The velocity drop by 35 degrees north or south is to about 860 mph. The only problem with this concept is that it doesn’t sustain a recurving circular flow. South bound winds are slower and would carry to the west.

There is only one structure that explains the full vortex structure of storms. That structure is an Electromagnetic particle vortex. Sorry folks the Coriolis effect is one of those things that needs sent to the dustbin of history (Trash for Americans).

The weather plasma flow linkages are being well studied now. There is no reason to continue to teach Coriolis Effect regards rotation of storms. It does have effect in things like the massive ocean currents and the generalized flows on earth of winds but it doesn’t affect rotation of storms. Even there we are learning that motion north and south from the equator is primarily electrical in nature.
