Answer:
Polar
Explanation:
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons. The hydrogen atoms have one electron each.
You are correct :) Red coat's genotype would be tt and the black bull's genotype would be Tt. You put those in a punnett square, and you'd get 2 tt's and 2 Tt's. Hope this helps! :D
Explanation: The energy pyramid describes how energy gets distributed through an ecosystem. The more there is of an organism on the energy pyramid, the more it gives overall to the ecosystem. The less there is of an organism, the less it gives to the ecosystem. Take the Floridian Everglades as an example. There is an abundance of sawgrass, and that makes up the foundation of the system, along with mangroves and such. But there are less of predators in the ecosystem because they only feed of of their prey like small mammals or fish. They never start the food chain, they end it.
Answer: 31, Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground
32, Sedimentary rocks can be organized into two categories. The first is detrital rock, which comes from the erosion and accumulation of rock fragments, sediment, or other materials—categorized in total as detritus, or debris. The other is chemical rock, produced from the dissolution and precipitation of minerals
33, Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
<u>Answer:</u>
<em>The purpose of genetically modified crops is increasing the food supply. </em>
<u>Explanation:</u>
<em>When crops are attacked by pests the yield of the crops reduces.</em> The natural pest tackling adaptations of the plant is not just enough to check the invasion of crops by pests. Introducing feature of pest resistance into the <em>genes of plant species will make them pest resistant.</em>
Genetic modification is the method used to achieve this objective. In genetic modification a previously absent feature is introduced into a plant species by various scientific techniques.<em> This feature can be pest resistance, chemical resistance, improved nutrient profile etc. </em>
