Answer: False

Explanation:

The wetlands are the shallow land regions which are occupied with water seasonally, permanently or temporary. These receives water from sources like river, lakes, ponds, rain and melting of glaciers.

The widespread loss of wetlands would have little effect on the overall health of the environment is a false statement because of the fact that wetlands can effect the climatic condition of a region as well these also maintain the biodiversity of the locations where they form. If the wetlands are lost the climatic condition of the locations will be adversely affected and the biodiversity will be reduced.

Which of the following are important when looking at a fossil? I. Where it's found II. How deep it's found III. The position it

kkurt [141]

The correct answer is - D) I and II.

When a fossil is found, one of the most important things that need to be looked at are the location where the fossil was found and how deep the in the ground the fossil was found.

The location of the place where the fossil is found is important as it can provide us with information about the environment of where the fossil lived, the geography of the place, was it land or water. Since reconstructions of the geological past have already been made, an experienced paleontologist will manage to use it without any problem.

How deep is the fossil found is also very important. The reason for that is that certain layer in the ground is a part of certain geological eon, era, period... By looking at the layer in which the fossil has been found we can relatively easily come to an information about its relative age.

A complete plant gene containing four introns and five exons is carried on a 6.0-kb DNA fragment. DNA sequencing analysis finds

damaskus [11]

Answer and Explanation:

the total length of the gene is 6,000 base pairs (or) 6.0 kb and it has five exons, four introns and a 1,000 base pair length flanking region for the transcribed region.

Hence, each exon has (1500/5) = 300 by

each intron has (3500/4) = 875 by and

flanking segment (5' and 3') length for the transcribed region would be (1000/2) = 500 bp.

The gene segment is as shown in the 1st diagram attached below

In eukaryotes, transcription takes place in the nucleus which results in the synthesis of hnRNA (heteronuclear ribonucleic acid). This hnRNA (pre-RNA) has both introns and exons, however when it is synthesized or while it is being synthesized the Spliceosomal complex removes introns from hnRNA and becomes converted into mRNA (messenger RNA) in the nucleus itself.

(second diagram explains further)

Now the synthesized mRNA reaches the cytoplasm. So, if mRNA collected from the nucleus and cytoplasm will have the same length of about 2,500 base pairs only. Therefore, after the commencement of northern blot analysis both mRNA will yield the same kind of result and have unique length.

Electrons are brought to the electron transport system by the oxidation of

Viefleur [7K]

Electrons are brought to the electron transport system by the oxidation of NADH and FADH2.

The electron transport chain is a group of proteins located within the inner membrane of the mitochondria which transport electrons. Electrons are passed from one member of the transport chain to another in a series of redox reactions, forming a proton gradient which is then used for ATP production.

NADH and FADH2 are reduced electron carriers which are oxidized into NAD+ and FAD near the beginning of the electron transport chain.

What type of unconformity did Hutton see at Siccar Point and how was this uniformity formed?

Alex

Answer:

Hutton's Unconformity

At Siccar Point, during the lower Silurian Llandovery epoch around 435 million years ago, thin beds of fine-grained mudstone were laid down gradually deep in the Iapetus Ocean, alternating with thicker layers of hard greywacke formed when torrents swept unsorted sandstone down the continental slope. Siccar Point is a rocky promontory in the county of Berwickshire on the east coast of Scotland. It is famous in the history of geology for Hutton's Unconformity found in 1788, which James Hutton regarded as conclusive proof of his uniformitarian theory of geological development.
