Explanation:

During transcription, initiation involves the attachment of RNA polymerase to the promoter and the start of RNA synthesis.
Group of answer choices

True

False

Answers

Answer:

true

Explanation:

True. During transcription, initiation is the first step in which RNA polymerase binds to the promoter region of the DNA molecule.

The promoter is a specific sequence of nucleotides located upstream of the gene that signals the start site for transcription. RNA polymerase recognizes and binds to the promoter sequence, forming a complex called the transcription initiation complex.

Once the transcription initiation complex is formed, RNA synthesis begins. RNA polymerase unwinds the DNA double helix in the region of the gene, exposing the template strand. It then catalyzes the synthesis of an RNA molecule by adding complementary RNA nucleotides to the growing RNA chain according to the base pairing rules (A-U and G-C).

So, the statement "During transcription, initiation involves the attachment of RNA polymerase to the promoter and the start of RNA synthesis" is true. Initiation is indeed the process where RNA polymerase binds to the promoter and initiates the synthesis of an RNA molecule based on the DNA template. This is a crucial step in the process of transcription, as it determines where and when the transcription of a specific gene will occur.

Answer:

Tropical rain forest, temperate woodlands, temperate forest.

Explanation:

Charles Darwin collected plants and animal specimens for the study of their distinct pattern of biodiversity. Darwin visited three biomes namely temperate forest, tropical rainforest, and temperate grassland.

What are biomes?

A biome is a biogeographical unit which is consist of a biological community formed in response to a shared regional climate.

Biomes may be spread over more than one continent. Biome is a term for habitat which can be comprised of a variety of habitats.

During the voyage, Darwin visited three biomes namely temperate forest, tropical rainforest, and temperate grassland for the study of biodiversity of plants and animals.

Thus, it can be concluded that temperate forests, tropical rainforest, and temperate grassland are the three different biomes that Darwin visited on his voyage.

Explain how competition for food can cause natural selection.​

Answers

Answer:

Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.

For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.

Answer: Primary succession: Glaciers, bare rock, lichen

Secondary succession: Wildfires, volcanoes, hurricanes, deforestation

Explanation:

Succession in ecology can be defined as gradual changes that occur in the biotic community in an ecosystem with respect to the changes that occur in the abiotic components of the environment. Primary succession initiate in an land which is not previously occupied by any living species. These includes the changes that occur at the primitive level on the land. That is the formation of glacier from the ice, bare rock will undergo withering and disintegration to form the soil, lichen are the biological composite organisms formed by the mutual association of algae and fungi. These lichens act upon the rocks to cause its withering by releasing the chemicals causing disintegration of the rocks.

Secondary succession occurs at those regions which have been colonized by the living species and get disturbed due to human oriented or natural disasters. Wildfires can be set up naturally, through volcanic eruption, or can be human induced can clear up the forests but some remains of seeds and deep rooted roots can help in growth of new plants which will again initiate the succession, again volcanoes, and hurricanes, are also natural hazards which can affect the population of species in an ecosystem. Deforestation is a human oriented practice in which vegetation cover or forests are clear cut. This will also cause loss of biodiversity.

1) Bacteria respond to changes in their environments, such as nutrient availability, by regulating their metabolic pathways. Describe two mechanisms that bacteria use in order to adapt to environmental changes. Include in your answer which mechanism is a short-term or long-term adaptation. (Pg. 364, paragraph 3, sentence 2; paragraph 4, sentence 1)

Answers

Answer:

Examples:

- Short-term adaptation: feedback inhibition

- Long-term adaptation: regulation of gene expression

Explanation:

Feedback inhibition is a mechanism where the product of a chemical reaction is utilized to modulate its own subsequent synthesis. In bacteria, feedback inhibition allows regulating different metabolic pathways in response to environmental conditions by modulating enzyme activity through enzyme reaction products. Moreover, bacteria may also respond to environmental inputs by long-term changes in gene expression. For example, bacteria contain transcription factors activated during stress, which are able to activate the transcription of particular genes into messenger RNAs (mRNAs) that would subsequently be used to generate particular enzymes by the process of translation. These transcription factors may bind to specific DNA motifs in order to promote transcriptional activity, thereby regulating the production of the corresponding enzyme.

Answers

Answer:

Mitosis

Explanation:

Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.

Which of these is a result of crossing over?
a.) Decrease in the number of chromosomes
b.) Exchange of proteins
c.) Exchange of genetic material
d.) Increase in the number of chromosomes

Answers

Part of one chromosome is exchanged with another.. so i’d say C possibly.

The result of crossing over is the exchange of genetic material that is present in Option C because this only happens in meiosis during the prophase and results in different gametes.

What is the importance of crossing over?

"Crossing over" is a process that occurs during meiosis of cell division in sexually reproducing organisms that produces gametes such as sperm and eggs. During crossing over, the genetic material in the parent cells' chromosomes is exchanged, resulting in new combinations of genes in the gametes, and the importance of crossing over is that it creates genetic diversity within a population.

Hence, the result of crossing over is the exchange of genetic material that is present in Option C because this only happens in meiosis during the prophase and results in different gametes.
