Which of the following mutations would be most likely to impair production of a normally functioning protein?

Biology
1 answer:
Sladkaya [172]3 years ago
6 0

Answer:

B

Explanation:

The deletion of a single base is the mutation that would most likely impair the production of a protein, because each aminoacid is coded by a triplet of three base pairs. So when one of the bases is deleted, the whole series of triplets is altered so the whole series of aminoacids in the protein would now be different.

Which statement best describes how artificial selection can decrease a population's biodiversity?
IrinaVladis [17]

The statement 'artificial selection decreases the rate of natural selection and change within a population' describes how artificial selection can decrease a population's biodiversity. It is a human-driven process.

<h3>Artificial selection</h3>

Artificial selection refers to the human-driven process by which different organisms (either plants or animals) are selected in order to combine desired features in offspring.

In artificial selection, organisms are mated (crossed) in order to select the progeny having desired phenotypic traits.

This process (artificial selection) leads to a decrease in natural genetic variation (biodiversity), which may have negative consequences in the successive rounds of selection.

Many people place bat boxes on their property to provide housing that attracts insect -eating bats. Explain how this activity ha
Pepsi [2]

Answer:

Bat boxes at homes provide housing to insect-eating bats which has two major positive effects on the environment:

  • Bat boxes provide bats a natural habitat and they act as natural pest control in the environment. They are very helpful for reducing or controlling the population of mosquito and balance the food chain in the environment.
  • Bat is known as very good pollinators which helps in the pollination of flowers or spread their seeds. So bat boxes at home increase pollination in nearby areas and increase biodiversity in the environment.

Hence, bat boxes at houses have a positive effect on the environment.

Consider the parts of a polar ecosystem and a desert ecosystem.
g100num [7]

Answer: Abiotic factor for polar: Ice

Abiotic for desert: Sand

Biotic for polar: Polar bears

Biotic for desert: Cacti

The types of factors are different because there are different set conditions for each ecosystem. A cactus is built for it's hot, dry ecosystem. If it were to move to a polar ecosystem it would not survive there. Same for the polar bear. It's built for polar regions. It has white fur to blend with the white ice to help it blend in and it's adapted to swim to get it's food source.

Scientists have conducted multiple experiments on cancer cells to determine how they reproduce. All
Ber [7]
I’d say the last one, the cancer cells lack inhibition and the do not stop reproducing. The rest of the answers don’t really make sense. The cancer cells can be controlled with chemotherapy so the first one is definitely wrong. And I do not believe that they contain stem cells. The last one is right because the reason cells become cancerous is because their growth inhibitors are broken or switched off, so they do not know when to stop growing and it becomes a problem for the body.
