Answer:
B. Directional selection
Explanation:
When natural selection starts to choose one phenotypes that is an extreme (as in, a really small neck or a really long neck), this is an example of <u>directional selection.</u> It makes sense for giraffes to have evolved this way, because the longer the neck, the more ably they can eat food from high branches. The more food they could get, the more chance of reproduction, the more "evolutionarily fit" they are.
Stabilizing selection is when national selection picks average phenotypes (like a medium-sized neck). Disruptive selection is when the extremes are both picked (like all the medium-sized neck giraffes die, and two different species start to emerge). Sexual selection is picking a mate based on traits. Clearly, those answers don't work here.
Answer:
CO2 and H2O are the reactants in the given reaction
Explanation:
The reaction that is written in the question is the general equation of photosynthesis.
In this reaction the carbon di oxide reacts with water to form glucose ,oxygen and water.The overall reaction is given below
6CO2+12H2O= C6H12O6+6O2+6H2O
carbon di oxide(CO2) and water(H2O) act as reactant in the above reaction.
Carbon dioxide, or CO2.
Plants produce oxygen for us to breathe, and in exchange they take the gas we breathe out: carbon dioxide.
Answer:
Explain how natural resources are identified:
Satellites are machines that are launched into space. They move around the Earth to get information that can help identify natural resources. How do satellites do this? Satellites scan the Earth’s surface to get information about its color and brightness. This information is used by a computer to make a “computer map”. Once they finish the "computer map" a person would look at the map and determine which materials are which. These maps are not for showing a person how to get from one place to another, but for showing what the surface of Earth looks like and what it is made of.
Why are natural resources unevenly distributed:
The formation of these resources requires certain conditions. For example, copper ores are formed where there is volcanic activity. Iron ores were formed a long time ago when certain substances combined to form sedimentary and other types of rocks. So, iron ores could be found more often in places with environments that were just right for the formation of these rocks. Graphite forms when another type of rock, called metamorphic rock, is formed.
Explanation:
This is what I put and I got all the information from the text on edge 2021.
<span>Plants either reproduce sexually or asexually, depending on the type of plant. In sexual reproduction, two germ cells, or gametes, fuse to create the beginning of a genetically unique offspring. In asexual reproduction, a plant cell splits in two to create a genetically identical offspring.</span>
