Sexual reproduction _________.a. enables males and females to remain isolated from each other while rapidly colonizing habitats. b. allows all animals to conserve resources and reproduce only during optimal conditions. c. yields more numerous offspring more rapidly than is possible with asexual reproduction. d. guarantees that both parents will provide care for each offspring. e. can produce genetic diverisity that may enhance survival of a population in a changing environment.

Answers

Answer 1
Answer:

Answer:

e. can produce genetic diverisity that may enhance survival of a population in a changing environment.

Explanation:

Genetic diversity is the amount of variation present in the genetic characteristics of an individual. It is basis for selection.

Random mating among individual which is done through sexual reproduction allows for variation in the population and diversity. Genetic diversity ensures continuity and adaptation of individual to adverse environmental condition, it is the basic for evolution.

Genetic diversity is also caused by various recombination, mutations and crossing over effect of homologous Chromosome.

Genetic diversity aids selection for improvement of various character.

Some protists form long, foot-like projections of their cell membrane and cytoplasm that are used for movement and to capture food. What is the name of these structures?cilia
flagella
mycelia
pseudopods

Answers

Answer;

-Pseudopods

Explanation;

-Pseudopods are temporary cytoplasmic projections of the cell membrane in certain unicellular protists such as amoeba.They are used in some eukaryotic cells to move around or to eat. Most cells that do this are called amoeboids. The amoeba is a common example.

-The functions of pseudopodia include locomotion and the capturing of prey. Pseudopodia are critical in sensing prey that can then be engulfed; the engulfing pseudopodia are called phagocytosis pseudopodia.

Pseudopodia or cytoplasmic extension

What cell activity is depicted in the figure?A) ATP production
B) DNA replication
C) protein synthesis
D) mRNA transcription

Answers

Answer: DNA replication

DNA replication occurs in the nucleus (eukaryote cells). DNA replication occurs in the interphase when the cell is growing, its carrying processes and its replication it’s DNA  

Once the cell is replication it does not divide so both theses process are not carried out together .Helicase is the unzipping enzyme. DNA polymerase, replicates the DNA molecules to actually build a new strand of DNA. Primase acts as an initializer  


DNA replication

Because, and to be honest there isn't much explanation to give since it's pretty much something we have to remember by heart more than anything, some of the enzymes a specific to this kind of process and isn't there in, for example, mRNA transcription.
