Answer:

Translocation

Explanation:

Translocation is a chromosomal defect in which part of a chromosome breaks off and reattaches backward on the same chromosome.

Translocation can happen due to many reasons like:

A) Some of the changes that arise around the time of conception or production of sperm or egg.

B) The inheritance of altered chromosome from father or mother.

Translocations can be divided into two forms:

Reciprocal translocation
Robertsonian translocation.

In reciprocal translocations, fragments of two chromosomes break off from two different places, break and swap each other's segments. While in Robertsonian translocation one chromosome attached with other.

What connects the nitrogenous based to each other?

Keith_Richards [23]

Hello!

There are two possible answers to this. The one I'm assuming you're looking for is hydrogen bonds.

Hydrogen bonds are the bonds which hold together the double helix shape of DNA. These bonds result from a positive and negative charge drawing two molecules closer to each other. These bonds are generally seen as weak, however, since there are so many of these bonds (as there are so many nitrogenous bases in one strand of DNA), the double helix strand is fairly strong.

Hope this helps!

How would you test the presence of starch in leaves?

Lesechka [4]

Answer:

1. Remove a green leaf from the plant

2. Boil the leaf in boiling water stop enzymatic reaction within cells in leaf

3. Put the boiled leaf in boiling tube containing alcohol extract (ethanol) chlorophyll ethanol dissolves Lipids in cell membranes.

4. Return to leave to the hot water soften the leaf and allows penetration of iodine

5. Remove leaf and perform the iodine test

Explanation:

starch is white powdery substance consisting of glucose which is used by plants as food the percents of starch in leaves evidence enough of the process a photosynthesis being carried out in leaves as the formation of starch necessitates photosynthesis.

I hope this helps :)

OlgaM077 [116]

A spider plant sends out runners that have buds. When planted, the bud grows into a mature plant. The resulting plant has one parent and is genetically identical to the parent.

Answer: Option C

Explanation:

Reproduction is of two types one is sexual reproduction and asexual reproduction. The asexual reproduction mostly involves only one parent and therefore the off spring that is born is genetically identical with the parent.

whereas in sexual reproduction that involves 2 parents the off spring born contains a genetic makeup that is a combination of 2 parents and thereby not genetically identical.
