Answer:

The correct answer would be - triploid plant.

Explanation:

Triploidy is a condition which can be defined as the 3 set of chromosome in an organism, the extra set of chromosome may be come from the maternal organism or the paternal derived. Maternal derived triploidy known as the digynic while in in the case of the paternal derived called diandric.

In this case the sperm goes under the meiosis so the each gamete will have one chromosome of each set (I I I) while the egg failed to undergo meiosis so the gamete carry complete set of chromosome ( II II II ) after fertilization the outcome will be Digynic triploidy (III III III).

Thus, the correct answer would be - triploid plant.

Your answer would be dendrites.

Dendrites look like branches coming off of the main body of the neuron. They receive electrical signals from axons, and then transmit them to the rest of the cell body.

Hope this helps!

The diploid number of chromosomes in the mustard plant, Arabidopsis thaliana, is 10. Knowing this, answer the following question
lukranit [14]

Answer:

10 chromosomes/sister chromatids

Explanation:

Prophase is the first stage of cell division (mitosis). Prior to the cell entering the actual division stage, it undergoes a phase where it prepares its content and most importantly undergo the duplication of its genetic material (DNA). This DNA are found as chromosomes. It undergoes replication of its DNA in the S-phase of interphase stage.

Since Arabidopsis thaliana has 10 chromosomes, and each chromosome holds one DNA molecule, 10 molecules of DNA will be present in the mustard plant's genome. These 10 molecules of DNA will be replicated on another copy of chromosome which is identical to the template. This chromosomes are called SISTER chromatids i.e. replicated chromosome. Each sister chromatids are held together at the centromere and are considered one individual chromosome until they separate during anaphase stage.

Hence, at the Prophase stage, before separation, each sister chromatid (replicated chromosome) is considered as one chromosome. Thus, in the mustard plant with 10 chromosomes, it will possess 10 sister chromatids or chromosomes at the Prophase stage.

N.B: When sister chromatids separate during anaphase stage, they will be regarded as individual chromosomes.
