What is Transcription?

The process in which  information of a strand of DNA is copied into a new m RNA molecule is known as Transcription.

The  enzyme responsible for transcription is RNA polymerase.

Transcription start when RNA polymerase binds to a promoter region at the start of a gene directly or through helper proteins.

Initiation, Elongation, and termination are the three steps of transcription.

Transcription is carried out with the help of enzyme RNA polymerase and some proteins known as transcription factors.

Enhancer and promoter sequences are the  DNA sequences on which transcription factors attach to initiate the transcription process by directing  RNA polymerase to the correct transcription site.

The transcription initiation complex is made up of transcription factors and RNA polymerase working together.

The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration help to

Answers

release carbohydrates

The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.

What is the significance of respiration and photosynthesis?

The photosynthetic process is the one that can make oxygen as a product, and later that oxygen is used by plants and other animals in the process of respiration, which is essential for life as the cell makes energy in this process. Plants and other chloroplast-containing photosynthetic organisms, such as blue-green algae, phytoplanktons, etc., can produce oxygen, which is then used in respiration to power the cell's activities.

Hence, the oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.

Two species of three-spined stickleback fish have been found together in five different lakes. The larger, bottom-dwelling species feeds on large prey close to shore. A surface-dwelling species feeds on small plankton in open water. DNA analysis shows that the two species in each lake are more closely related to each other than they are to any of the other species in the lake. Which prezygotic mechanism most likely allowed divergence of an ancestral species into these present-day species

Answers

Answer:

The answer is "Sympatric speciation due to disruptive selection"

Explanation:

Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.

23 In any environment or ecosystem, organisms can have several different types of relationships. Three types of relationships are described below. Ecological Relationships Relationship Description Barnacles (small crustaceans) adhere to the skin of a whale in order to be deposited in a new location that is abundant in resources. The whale does not appear to be affected. Fleas attach to the skin of warm-blooded animals, feed on their blood, and make the animals itch. Fungal mycorrhizae live on plant roots and increase the plant's ability to absorb nutrients. The mycorrhizae are provided with carbohydrates from the plant Y Y Z Which of these correctly describes the relationships between the organisms? A X: mutualism Y: parasitism Z: commensalism C X: parasitism Y: commerisallsm Z: mutualism B X, commensalism Y: mutualism Z: parasitism D X: commensalism Y; parasitism Z: mutualism​

Answers

Answer:

The correct answer is X: commensalism Y: parasitism Z: mutualism

Explanation:

Took a test with the same question

The ecosystem organisms have several different types of relationships. The ecological relationships affect the organism interaction as X: commensalism Y: parasitism Z: mutualism. Thus option D is correct.

What is an ecological relationship?

An ecological relationship is an overlapping relationship that an organism has with the environment and is characterized by five types as

competition, predation, commensalism, mutualism, and parasitism.

The ecological system all organisms are dependent on each other for food and growth. Thus the fleas attached to the skin of the warm-blooded animals are a sign of parasitism and fungus increases the plant's growth is a sign of mutualism.
