Answer:
Food and water
Explanation:
Food and water are the only thing that somebody needs to survive. Although, some people might want shelter, it is not a nessecity for you to survive. Many people today are homeless because they spend money on things they don't need such as, clothes, electronics, etc. It is important to have the things nessecary for you to live, rather than incentives.
Answer:
directional selection
Explanation:
The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.
When performing Cardiopulmonary Resuscitation or CPR you have to follow the following steps:
1. Make sure that the scene or environment is safe.
2.Tap the patient and ask if he/she is okay, if the victim is non-responsive proceed to CPR.
3. First, perform the head-tilt chin-lift maneuver to open the airway.
4. Start by giving 30 chest compressions and 2 breaths thereafter. Watch for response from the patient and if there is none, repeat the cycle.
Therefore, when performing rescue breathing, tilt the head of the patient.
Your body can store some fuels in a form that offers muscles in a immediate source of energy. Carbohydrates such as sugar are readily broken down in glucose, the part of your bodies principal energy source.

Answer:
a) Individual 1
b) Overall, the higher the number of mutant alleles, the greater is the concentration of cysteine in urine relative to normal values.
c) The hypothesis may be correct. If number of mutant allele in SLC7A9 is higher than number of mutant allele in SLC3A1, then concentration of cysteine in urine is lower. This means that transportation of cysteine is affected by a greater extent if mutant allele in present in SLC7A9 genetic sequence
d) concentration of cysteine is affected by mutant allele which is a complex protien. If complex protien is low cysteine is not transported back and its concentration in urine is higher
Explanation:
a) Can be inferred easily from table. Higher the mutant allel that is negative, higher is the concentration of cysteine. Hence greater the chances of cystinuria.
b) As explained in part a
c) Observe the pattern on concentration of cycteine and number of - allele. If cysteine is not transported back then its concentration in urine will be higher.
d) The complex protien helps in transportatino of cysteine by binding to it. In the absence of the ocmplex protien, cysteine tends to behave like polar molecule and stay in water that is in excess in urine.
