Homozygous: this means that the man has two genes for unattached earlobes, so whichever of these gene genes is transmitted to the child, it will be unattached. Since having unattached earlobes is a result of a dominant gene, one such gene is enough and the child will definitely have an unattached earlobe.
Answer:
She can conclude that the reaction started with three nitrogen atoms because she can be based in the law of conservation of matter which states that the amount of matter in a system is conserved: there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.
Explanation:
In science, a law is a general statement that explains a large number of observations. One law that provides the foundation for understanding in chemistry is the law of conservation of matter: it states that in any given system that is closed to the transfer of matter (in and out), the amount of matter in the system stays constant, or in other words, the amount of matter in a system is conserved.
So, in this case, for Marcia to conclude that the reaction started with three nitrogen atoms, she can be based in the law of conservation of matter, and because the matter of that system is conserved, there were three atoms of nitrogen in the reactants and they produced three atoms of nitrogen.
Answer:
grass clippings contain nitrogen and potasiom which can act as a fertilizer for plants but alos works as a mulch it keep light away froom weeds and retain soil mosture.
Explanation:
The biotic factors can be defined as those living elements of an ecosystem that affects the other members of the ecosystem and also shapes it. The examples include animals and plants. The abiotic factors can be defined as those elements which are non-living and have effect on the other components of the ecosystem. The examples include water, air, soil etc.
A rabbit having long ears in order to disperse heat is adapting to the abiotic factor, i.e. the heat.
The spines of cactus are an adaptation to another abiotic factor, water.
The bright red color of the petunia is to attract the hummingbirds for pollination. They are adapting to the biotic factor (hummingbird).
The blending ability of stick-bugs to hide in the trees is an adaptation to the biotic factor (predators).
The diving ability of the moth is an adaptation to the biotic factor bat, in order to escape predation.
The adaptation of the lizard to sun itself on the rock in order to stay warm is in response to an abiotic factor (heat).
Answer:
K+-coupled.
Explanation:
The transport of the solutes may occur along the concentration gradient or against the concentration gradient. Two main types of transport that occur in living organism are active process and passive process.
The passive transport do not require the energy for its transport whereas the active transport require energy. The K+ coupled transport do not require any energy molecule for its transport and easily transfer by the leaky channel. Hence, the K+-coupled transport is not the common active transport.
Thus, the correct answer is option (C).
