Since prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.

<h3>What are prokaryotic cells?</h3>

Prokaryotic cells are cells that are characterized by the absence of a nucleus or any other membrane-bound organelles.

On the other hand, eukaryotic cells have the presence of a membrane-bound nucleus that stores their genetic material.

Another important feature of prokaryotic cells is that they are haploid in nature i.e. they do not have chromosomes that occur in homologous pairs and have just one chromosome.

Therefore, it can be said that because prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.

Differentiate external and internal environment factors in influencing Gene expression

Scilla [17]

Answer Internal and external environmental factors, like gender and temperature, influence gene expression. ... Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, thereby influencing the way an organism develops and functions.

Research has found that chimpanzees in one area make spears to help them hunt bushbabies (African lorises). The chimpanzees loca

castortr0y [4]

Answer:

1. Yes

1. True

Explanation:

A.

Yes, it is a nonhuman primate cultural example: Despite the fact that many nonhuman primates lack apparent cultural traditions in the same manner that humans do, primatologists have uncovered a number of behavioral habits that differ between populations and are passed down through socialization and language interaction. The employment of tools by chimps for hunting is one of the most prominent examples of this. Chimpanzees in the African Savannah have been observed fashioning sticks into weapons to hunt bush infants, according to researchers. In each example, a chimp changes a branch by snapping off one or two ends and sharpening the stick with its teeth. The spear is then jabbed into the bottom of the trunk, where the bush infants slumber. Because this complicated behavior appears to differ between communities, it is thought that chimpanzee tool usage is socially acquired, and hence a cultural behavior.

B.

Chimpanzees hunt in groups so that they may corner their prey even if the canopy is continuous. Each chimpanzee within the hunting parties has a specific function to play during an arboreal hunt. Drivers are responsible for keeping the prey moving in a specific route and following them without trying to grab or catch them. Blockers are positioned at the base of the trees, climbing up to stop prey from fleeing in the other direction. Chasers move swiftly and attempt to capture the prey. Finally, when one monkey approaches, ambushers hide and flee. The food is delivered to all members of the hunting group once the animal has been trapped and slaughtered.

In maize, liguleless (l) is recessive to having ligules (L), and dwarf (d) is recessive to tall (D). These two genes are linked

bearhunter [10]

Answer:

given,

LL║ll and DD║dd,

after crossing over, Ld║Ld × lD║lD

LLdd × llDD

in F1 generation, they will give, LLll, DDdd, LLDD, lldd → LlDd

in eF2 generation, the offsprings will be, LLll × DDdd

LLDD ,LLdd, LLDd, llDD, lldd, llDd, LlDD, Lldd, LlDd

1. yes, these genes are coupling.

2. → phenotypes of parental genes = ligules, liguleless, tall and dwarf

genotypes of parental genes= LLdd, llDD i.e; heterozygous

→ phenotypes of F1 generation = 25% Ligules, 25% tall, 25% ligules-tall, 25% liguleless-dwarf

genotypes of F1 generation = heterozygous ; LlDd that is ligules-tall

3. recombination frequency= no of recombinant / total progeny × 100%

= (1344+1344) / 6156+1344+1344+1156 × 100%

= 2688/ 10000 × 100%

= 26.88 %

that means linkage happened

and the map distance is 26.88 map unit.
