Cell membranes are made of phospholipids to keep the cell's water (cytoplasm) in and everything else out. so your answer would be D <span />
The answer is <span>a. most living organisms can survive in environments with several different temperature and salinity levels.
</span>Aquatic plants and animals depend on dissolved oxygen for respiration. The other abiotic factors that impact their life in an aquatic ecosystem are temperature, salinity, and flow and they determine the quality of their life. <u>It is not true that most living organisms can survive in environments with several different temperature and salinity levels.</u> On the contrary, a few species can live in <span>environments with several different temperature and salinity levels, for example, some bacteria. The most organism can survive in a specific range of abiotic factors.</span>
Answer:
Diploid.
Explanation:
DNA is present in the genetic material of all the eukaryotic and prokaryotic organisms.The eukaryotic genome contains DNA wraps around the histone proteins. Multiple distinct chromosomes are present in the eukaryote genome.
The eukaryotic genome are generally linear structure with the two copies of each chromosome. This makes the eukaryotic genome as diploid structure.
Thus, the correct answer is option (1).
Answer:
The probability of getting a dwarf and pink female is 1/2
Explanation:
In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele where coats are normally brownish.
A dwarf female from a pure line will have Xd Xd where d represent the recessive trait and the female is also brownish (pp).
A pink male from a pure line will be XPY where P represent the dominant allele but not a dwarf (D).
Xd Xd Xp Xp
XD XDXd XDXd XP XPXp XPXp F1 generation
Y XdY XdY Y XpY XpY
P XDXd x XdY XPXp x XpY
XD Xd XP Xp
Xd XDXd <u>XdXd</u> Xp <u>XPXp</u> XpXp F2 generation
Y XDY XdY Y XPY XpY
The probability of getting a dwarf and pink female is 1/2
Answer:
by the nitrocellulose membrane filter method. (more info below)
Explanation:
Genetic relationship between mycoplasma as determined by nucleic acid homology. DNA from each of the mycoplasma isolates tested was reacted separately by complementary RNA synthesized with homologous or heterologous DNA as a primer. The amount of DNA-RNA hybrids formed was tested using the method of the nitrocellulose membrane filter.
hope this helped!
