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
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.
Do multicellular organisms GROW? Do multicellular organisms DEVELOP
Answer:
It has physically increased in size. Often, growth of a multicellular organism occurs as more cells are created. In unicellular organisms (like bacteria), growth still occurs. ... For this reason, most biologists will tell you that development only occurs in multicellular organisms, not in unicellular ones.

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 inheritanceNote: 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 maleParental) 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 maleParental) 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 maleParental) 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 maleParental) 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 maleParental) 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 maleParental) 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)
how does coriolis effect affect the climate zones in the world? PLEASE HELP! I WILL GIVE BRAINLY TO PROPER ANSWER!
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.
how does renewable energy affect non-human organisms? (plants, animals, bacteria, fungi,etc.)
Answer:
Non Renewable Energy Impact on Environment
All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.
Explanation:
Why is it dangerous to have too much carbon dioxide in the atmosphere
Answer:
too much CO2 is toxic for humans to inhale. we rely on plants to absorb CO2 and produce O2. If they was a sudden extinction of all plants on earth, this would lead to a rise of CO2 which would reduce O2 air quality. (not good at all)

hope this helps :)
Explanation:
Someone please help ill give you brainliest!!!
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.

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
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).

Is better for an ecosystem to have high or low species abundance?
Answer:
There should equilibrium state in the ecosystem in case of number of species, if there will be high species abundance there would be higher rate of competition in between the species also the predation can be easily seen in such ecosystem. On the other hand if the species abundance is low then the competition between the species and predation can not be seen.What are 4 agricultural products presently being worked with and studied in Nc biotechnology?
