MOST FLOWERS ARE STANDING STRAIGHT UP. FLOWERS ARE MOST LIKLEY TO REPRDUCE THROUGH THE WIND. SINCE THE FLOWER IS STANDING STRAIGHT UP IT WILL CATCH MORE.
Explanation:
im d u m b and left caps lock on.
The the structures in flowers increase their odds for reproduction and most flower are standing straight up and flower are most likely to reproduce through the wind. Since the flower is standing the straight up it will catch more.
What is pollination?The term pollination has been defined as the act of the exchanging the pollen grain from the anther which is male part of the flower to the stigma female part of the flower. This is the main objective of each and every living organisms.
Reproduction has been defined as the process carried out by the living organisms and during the process of the reproduction the living organisms produces their own young ones and feed them. Reproduction has been the supreme quality of living things.
There has been two types of the reproduction and these are the sexual and asexual reproduction. The process of the reproduction in which two parents are involved has been said to be sexual mode of the reproduction and the process of reproduction in which only the single parent has been involved is known as the asexual mode of the reproduction. The example of the asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, The the structures in flowers increase their odds for reproduction and most flower are standing straight up and flower are most likely to reproduce through the wind. Since the flower is standing the straight up it will catch more.

(1) Use complete sentences to explain the advantage of using binomial nomenclature in the system of classification. Also explain what kind of information you can get about the organism from its scientific name.
(2) The diagram below shows the branching tree diagram for humans. The text box below it shows the set of derived shared characteristics for the branching tree.
A slanting, horizontal line is shown. On the extreme left, there is a label that says Common Ancestor. Along the slanting, horizontal line there are five dots labeled from left to right as 1, 2, 3, 4, and 5. There is one vertical line between each of the consecutive five dots. The lines are labeled from left to right as Perch, Frog, Pigeon, Rats, and Human. A text box below the branching tree diagram is labeled Derived Shared Characteristics. In the box it says from left to right, Terrestrial during all stages, Jaws, Walking on two legs, Mammary glands and hair, and Four limbs.
Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. From the text box, select a shared derived characteristic that frogs and pigeons have. Explain why you think frogs and pigeons share this characteristic.
Answers
Answer:
The advantage of using a binormal nomenclature in the system of classification is it formally names animals of a species of living things by giving a two-part name which either is based on Latin or other languages. One Part is used to classify the genus and the second part of the specific name. An example of this would be ( for humans ).

Availability of waterTemperatureNatural DisasterWhat is Natural Selection?
Natural selection is a set of characters that deal with the most favorable variations that are promoted by nature.
As predators, the height of legs, fur, the color of the body, size of the body, and size of the beak is not related with environmental changes. It can also be said that these characteristics lead to natural selection depending on the conditions, such characteristics are not linked with environmental changes directly.
Therefore, the three examples of environmental changes that can influence natural selection are the availability of water, temperature, and natural disasters.

Lauren makes an art piece using the densities of various liquids to create layers of colors. She first determines the density of each liquid. Then she pours them into a glass container and watches them separate into layers.
Answers
Answer: you need to divide mass by volume, the honey will sink to the very bottom and the corn oil will float to the top
Explanation:
Lauren needs information like the mass of each substance with respect to its volume in order to estimate the density of each liquid specifically.
What is Density?Density may be defined as a type of physical property that significantly deals with the description of how much space an object or substance takes up with respect to the amount of matter in that object or substance.
In a more simple sense, it is characterized as the measurement of quantity or mass per unit of volume in a particular substance.
According to the question, Lauren calculates the densities of each liquid with the help of the following formula:
Density = Mass/Volume.According to the densities given in the question, the liquid that has a density less than that if water, it will float in water. While the objects or liquids that have a density more than that of water, it will sink to the very bottom.
So, corn oil will float over the surface of the water, while honey will sink to the very bottom.
Therefore, Lauren needs information like the mass of each substance with respect to its volume in order to estimate the density of each liquid specifically.
