Answer:
There are difference in the TCA cycle of both prokaryotes and eukaryotes. In prokaryotes mitochondria is absent of TCA occurs in the cytosol. In eukaryotes it occurs in the mitochondria.
<span>In this pathway, an NADP-dependent enzyme </span><span>catalyzes the dehydrogenation of </span><span>D-threo-isocitrate</span><span> to </span>2-oxoglutarate<span>, while eukaryotes employ an NAD+-dependent enzyme</span><span>. Another difference is that while in most eukaryotes the conversion of </span><span>(S)-malate</span><span> to </span>oxaloacetate<span> is catalyzed only by an NAD-dependent enzyme, p</span><span>rokaryotes that employ this variation of the TCA cycle possess an alternative quinone-dependent enzyme.</span>
Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.
ex. sickle cell disease - a single letter swap in the gene that encodes the hemoglobin molecule results in deformed red blood cells
Hope that helps.
Get twenty people, from various genders and ages, to be your testees. Create a random test that has both analytical and logical problems, and get the 'testees' (I have no idea if this is a word or not) to do the test before and after spending time outdoors.
An independent variable is how much time they spend outside, and the dependent is how well they function afterwards. (I think).
The constant is what stays the same, so most likely the tests in this case (if taking my example)
I don't really know what you mean by control, though...
This is what I would've done if it was my homework assignment, I'd suggest looking over my answers to see if they're accurate or not. Hope I helped, and good luck.
Viruses do not have nuclei, organelles, or cytoplasm like cells do which is why they have no way to monitor or create change in their internal environment.
Answer:
The answer is - Biomass decreases as energy is transferred from one level to another.
Explanation:
The options are;
A. Chipmunks and insects can occupy the same niche.
B. As the number of bears in this community increases, the number of chipmunks will increase.
C. Insects are classified as omnivores in alpine meadow communities.
D. Biomass decreases as energy is transferred from one level to another
The answer is D. Biomass decreases as energy is transferred from one level to another
The energy pyramid being referred to is in the attachment below.
Biomass is an organic renewable source of energy derived from plants and animals. As animals at the lower trophic levels are consumed by animals at the higher trophic levels there is transfer of energy, however it is not all the energy that are transferred equally. As a result, at each trophic level there is decreased energy and biomass that is transferred from one level to the other.
