Characteristics of a ant

Answers

Answer:

Their bodies are covered with a hard armor called the exoskeleton. Most ants are either red or black in color and length can be anywhere from 1/3" to 1/2". Like other insects, they have six legs; each with three joints. Ants have large heads with compound eyes, elbowed antennae, and powerful jaws.

Explanation:

The ant is an arthropod that has the characteristics of arthropods, such as the jointed legs, the exoskeleton that protects it, and the segmented body; apart from that, it has an antenna, etc.

What are the features of the ants?

The ants belong to arthropods, and the arthropods are non chordates. The special feature of the arthropods is that their bodies are segmented into three parts, such as the head, thorax, and abdomen, and they have an exoskeleton similar to that of the ant. Ants are eusocial animals, meaning they live in groups. Different types of ants are present in different geographical locations, and some of them produce toxins that are harmful to other animals.

Hence, the ant is an arthropod that has the characteristics of arthropods, such as the jointed legs, the exoskeleton that protects it, the segmented body, etc.

Answers

Answer:

Kingdom Animalia

Explanation:

Kingdom Animalia is one of the seven kingdoms living organisms are classified into. The Kingdom contains organisms called ANIMALS. They are eukaryotic i.e. possess a membrane-bound nucleus. Animals are heterotrophic i.e. they rely on other organisms for their source of energy (food).

In order to break down this food via metabolism, animals need oxygen to do so. This process is called respiration, and it yields energy in form of ATP, which is used by their cells to carry out cellular functions. Therefore, a heterotrophic multicellular organism that relies on oxygen to metabolize its food belongs to KINGDOM ANIMALIA

How is DNA expression regulated in individual cells?

Answers

Answer:

Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription (when the information in a gene's DNA is transferred to mRNA). Signals from the environment or from other cells activate proteins called transcription factors.

Explanation:

Gene regulation can take place at any stage of gene expression, although it often happens during transcription when the data from a gene's DNA is converted to mRNA.

What is gene regulation?

Proteins known as transcription factors are activated by signals from the environment or from other cells.

Limiting the amount of mRNA that is generated from a certain gene regulates transcription.

Eukaryotic gene expression is regulated by the nucleus-based mechanisms of transcription and RNA processing and the cytoplasm-based activities of protein translation.

Therefore, the translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.

The green beetles, due to their natural grass camouflage will have a much smaller chance of being eaten than the yellow ones which stand out. While the yellow ones get eaten the green thrive and reproduce. Soon, there won't be anymore yellow bugs. They'll most likely die out or breed with the green ones to make offspring of a more green color.
