A membrane that allows only some materials to move in and out of the cell is

Answers

Answer 1
Answer: A membrane like that is called semi permeable, because only certain materials can pass through it.

If a gene has only one allele, how many different traits can the allele produce?

Answers

One allele can only produce one trait

What is an allele in bio?

Answers

An allele is like a trait or a specific gene.
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

Which type of genetic exchange occurs among bacteria in which dna is carried into a bacterial cell by means of a virus?

Answers

Answer:

Transduction

Explanation:

Among the three types of gene transfer in bacteria, transduction does not require physical contact between the two bacteria cell. Viruses that infect bacteria accidentally move pieces of chromosomal DNA from one bacterium to another. These viruses that infects bacteria are called bacteriophages.

Simply put, transduction is a process of genetic recombination in bacteria which involves the incorporation of the genes of a host cell (bacterium) into the genome of a viral cell (bacteriophage) and then conveyed to another host cell when the bacteriophage infects it. The process of transduction is of two types; generalized and specific depending on whether any gene or specific gene is transduced respectively.

The aim of these viruses when they infect bacteria cell is to harness the ability of bacteria to replicate, transcribe and translate their genetic material and use it to procreate into many virons or complete their viral particle.

Explain why changes in climate can result in the extinction of a species.

Answers

The changes in environment can cause the raising of the sea level, which can push animals further inward, which in turn destroy habit, as they began to get clumped together vegetation begins to go away, thus resulting in less species, also hotter climate makes sure that animals with very heavy coats of fur, die out pretty quickly if not cooled (over heating)
Changes in climate (too hot or too cold) can affect multiple spiecies of animals due to disappearance of their habitats or/and food.
Every living animal and plant is part of the food chain. If the food chain is broken, many species would be in danger of extinction.

Which statement is true? a. Prokaryotic cells have multiple membranes. b. Eukaryotic cells have one membrane. c. Prokaryotic cells do not have a membrane. d Eukaryotic cells have multiple membranes

Answers

Eukaryotic cells have multiple membranes Is TRUE

  • Cell is surrounded by a cell membrane.
  • Some organelles are also covered by membranes.
  • Nuclear membrane  is also present which separate cytoplasm from nucleus.

What is eukaryotic cell?

  • Eukaryote, any cell or organism that possesses a clearly defined nucleus.
  • The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes are located.
