Bloodstain shape is determined by the angle between the flight path of the droplet and the surface that it impacts (Fig.1). When a drop of blood strikes a horizontal surface from the perpendicular (at an angle of 90°, Fig.2), the resulting bloodstain will be round. As the angle between the blood drops’ flight path and the target surface decreases, the length of the resulting bloodstain increases and the width decreases; in other words, the bloodstain becomes longer and narrower as the size of the angle decreases (Fig.3). A blood drop that has impacted a target surface from an angle of 12° will be long and narrow (Fig.4). Also present on these long, narrow stains is a ‘tail’ (Fig. 4). As the drop of blood impacts the target surface, the main body of the droplet will stick to the surface. A small portion of the blood drop will tear off from the top and continue in a forward direction. This secondary spatter has the appearance of a tail.

The model in the image justifies this statement that the body carries out critical life functions through systems of specialized cells like Nerve cells, blood cells, and reproductive cells.</h2>
Explanation:
Steroid hormones are derived from cholesterol responsible for the regulation of a wide range of physiological functions.
DNA is a self-replicating material which is present in maximum living organisms as the main integral part of chromosomes. It acts as a carrier of genetic information.
This hormone consist of a different cell, which is getting extracted by another cell through a steroid receptor.
Ribosomes, also known as protein builders are minute particles consisting of RNA. Proteins are needed for several cellular functions like repairing damage or controlling chemical processes. These functions would be impossible without the help of all specialized cells.

The correct answer to this is the butterfly. hope this helps :)
Answer:
1 . annual: A plant that completes its life cycle within a year's time
2 . dicotyledon: A flowering plant with seeds having two seed leaves
3 . cotyledon: A seed leaf
4 . entropy: A running down
5 . endosperm: A food storage tissue
6 . monocotyledon: A flowering plant with seeds having one seed leaf
Explanation:
Annuals are plants that grow, reproduce, and die in one year or less. These are mostly herbaceous plants. Some of the examples of annuals are corn, geranium, and marigold.
Flowering plants are categorized as dicotyledons and monocotyledons based on the number of seed leaf present in their seeds. The dicotyledons have two seed leaves in their seeds while monocotyledons have only single cotyledon in their seeds. Here, cotyledons represent the seed leaf associated with the embryo within the seeds. The cotyledons may function as storage organs. They absorb the food reserves and become large, thick, and fleshy. Gram is a dicot plant while wheat and corns are examples of monocots.
A mature seed of flowering plants has an embryonic plant and food reserved. These food reserved may be present in the form of cotyledons and/or endosperm. The endosperm is a nutritive tissue and is triploid in flowering plants.
Entropy represents the energy of a system that can not be used to perform any task. This energy rather makes the system random or unorganized. During energy transfer, the part of the energy lost as heat represents entropy.
