We alter carrying capacity when we manipulate resources in a natural environment. If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive. If the population exceeds the carrying capacity for a long period of time, resources may be completely depleted and Then the population size remains relatively the same. If abiotic or biotic factors change, the carrying capacity changes as well. Natural disasters can destroy resources in an ecosystem. ... If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive.
Explanation:
Answer:
Protein phosphorylation can activate/deactivate protein function, while small RNAs can be used for repressing translation of mRNAs through the RNA interference (RNAi) pathway
Explanation:
Protein phosphorylation is one of the most important posttranslational modifications (PTMs) that acts to activate, inhibit, or reversibly switch on/off protein function. Protein phosphorylation confers a reversible and versatile process that cells use to transmit signals and respond to environmental stimuli. This PTM is well known to modify the tertiary structure of the protein and thus activate/inhibit protein functions such as, for example, signaling pathways associated with protein interactions. In consequence, protein phosphorylation can be used by a cell to regulate Brec activity. On the other hand, small non-coding RNAs (ncRNAs) such as, for example, microRNAs (miRNAs), small interfering RNAs (siRNAs), and PIWI-interacting RNAs (piRNAs), are regulatory molecules that bind by complementary base pairing to messenger RNAs (mRNAs) in order to repress translation and/or trigger mRNA degradation through the RNA interference (RNAi) pathway. The RNAi pathway is widely used in molecular biology to silence genes of interest (for example, in this case, the gene that encodes for the kinase D protein).
Ok this is going to make me work sadly with a time restraints that I have I will be unable to draws the first picture however the rest I can do. 2. vestigial structures are generally parts of an animal's body that is unnecessary and no longer used. specifically whales have vestigial pelvis bones and as you know they dont walk as for my body the appendix is also a good example it kinda just sits there waiting to become infected. 3. embryos from separate organisms in very early stages look VERY alike and can be incredibly difficult to tell them apart from one another. 4. Everyone's favorite dioxy ribonucleic acid or DNA can show ancestry they do this by being similar like my DNA isnt exactly the same as my mothers however there are more then enough similarities in our DNA to tell that we are related. This works for any and all animals as long as they have salvageable DNA so dinosaurs dont count. using DNA we can also tell that I'm more closely related to a dolphin than a shark and I'm more closely related to sharks than sponges. hope I answered what you were looking for thoroughly
Dr. Evil has just discovered a way to prevent mating from occurring during meiosis in the gametes of his lab rats. the effects her discovery would have on laboratory mice is that prophase I would be interrupted and there would be reduced genetic variation in the offspring of the mice. because crossover occurs during prophase I of meiosis I and results in genetic recombination, which promotes genetic variation. If this is avoided, genetic variation would be significantly reduced in the offspring.
<h3>What happens in prophase 1?</h3>
Prophase I – in this stage, the condensation of the chromosomes occurs; the temporary disappearance of the carioteca; disappearance of the nucleolus and the duplication of centrioles to the poles of the cell. In prophase, the exchange of genes (crossing-over) also takes place, through the exchange of pieces between homologous chromosomes.
With this information, we can conclude that Prophase I is the first stage of meiosis I. In it, the pairing of homologous chromosomes occurs and a phenomenon known as crossing-over can occur.
