Answer:

Any preserved remains, trace, or impression of any once-thriving living thing from the past geological age is known as a fossil. This comprises exoskeletons, bones, stone imprints of animals or microbes, shells, hair, petrified wood, objects preserved in amber, DNA remnants, coal, and oil. The fossil record is the term used for the totality of fossils.  

The scientists use the prevailing fossils to show what the intermediary forms between the organisms may appear like. It is hard for the scientists to locate the fossils of the transitional forms as the formation of the fossils of the transitional forms may have never taken place because of the environmental conditions. In case if they did have formed, then the natural procedures like erosion may have demolished them.

soldier1979 [14.2K]

The question is incomplete as it does not have the options which are:

A) n+1; n+1; n-1; n-1

B) n+1; n-1; n; n

C) n+1; n-1; n-1; n-1

D) n+1; n+1; n; n

Answer:

Option-1

Explanation:

The laws of inheritance were concluded from the result of Mendel's experiment which is based on the fact that gametes are formed. Later research suggested that gametes are formed by the process of meiosis which takes place in two phases and recombination is a characteristic of Meiosis.

If during anaphase I of meiosis I, the alleles fails to separate that is nondisjunction takes place at anaphase I, Then the resulting daughter cells will have unequal distribution of chromosomes.

One daughter cell will receive 1 extra copy of the chromosome while another daughter cell will receive 1 less chromosome therefore ploidy level will be n+1 and n-1.

During meiosis II, 2 more daughter cells will be formed with the same ploidy level therefore in last the meiosis will result in 2 (n+1) and 2 (n-1) cell.

Thus, Option-1 is the correct answer.

Electricity is added to recharge a battery. What is added to ADP to form ATP?
White raven [17]

Electricity is added to recharge a battery. A third phosphate group  is added to ADP to form ATP.

ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.

ADP is converted to ATP by the following reaction:

ADP+Pi+energy⇄ATP

The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.

ikadub [295]

The type of mutation that occurred here is an inversion of three nucleotide bases (Option A).

<h3>What is an inversion?</h3>

An inversion is a type of mutation where linear order of nucleotide in the mutated sequence is inverted.

In this case, we have an inversion that involves the following bases (bold highlighted) AATCGC TAC GCACGTCAG and AATCGC CAT GCACGTCAG.

In conclusion, this mutation is an inversion of the genomic sequence (Option A).
