Answer:

Explanation:

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.

Answer:

The answer to your question is below

Explanation:

An atom is a diagram which describes the parts of an element. In an atom, we can observe the nucleus formed by a nucleus and shells. In the nucleus are located the protons and neutrons and in the shells are the electrons.

Elements are all the pure substances that are not combined with other substances and have specific physical and chemical properties.

When there is cold in the environment, people lives in warm shelters and wear warm clothes in order reduce the impact of cold environment.

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.

Describe the formation of tissues fluid and lymph​
defon

As fluid enters the tissue space from the blood stream pressure builds up in this space and as this hydrostatic pressure increases it causes the interstitial fluid to diffuse into the lymphatic capillaries once the interstitial fluid has entered the lymphatic capillaries it is called lymph
