The results that have been produced from the improved agricultural practices are the following: increased biodiversity, increased productivity, and increased profits. Improved agricultural practices aim to produce food for consumers that are safe and wholesome. If these agricultural practices are improved and applied, there will be an increase in biodiversity as well as increased in productivity. If there is an increase in production, there is an increase in profits.

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.

xeze [42]

Answer:

Their spores are produced in sac-shaped structures.

Their spores are produced in club-shaped structures.

Their reproductive cells have flagella.

Their reproductive cells have several nuclei.

They live in wet places.

They live in dry places.

Explanation:

The Chytridiomycota, often called chytrids, are unique among all fungi in having motile stages in their life cycles; no other fungi have this trait. These motile stages take the form of zoospores, single cells with a single posterior (at the rear) flagellum.
