Answer:

1. A Struggle for Survival

2. survival will reproduce

3. Superior adaptive variation

Explanation:

1. Observation: overproduction of offspring that can possibly survive.

CONCLUSION: A Struggle for Survival, most of this offspring fight for food and water.

2. Observation: variation in species: member of the same species have different ways of identification, which are color, sex, e.t.c

CONCLUSION: Those individuals that survive and reproduce do so in consequence  of "superior adaptive variation" (they are "more fit")

3. Observation: Variation heritable through selection: most survival pass there favourable adaptation to their offspring.

CONCLUSION:  Superior adaptive  variation will be passed on to offspring generation.

Janelle should talk to any trusted adult for advice. I'm assuming she can't just get her local physician any time she wants to talk to them. Someone else who drinks is not reliable. The people at the party will probably drink too.

Answer No 2:

The correct option is C. <u>Substitution of 3rd N-base to go from UCU TO UUU </u>has the potential to cause more damage.

Answer No 3:

UCU codes for the amino acid serine whereas the code UUU is for phenylalanine. A change in this base has caused the entire amino acid to change which will result in the formation of the wrong protein.

Whereas the changes in the base sequence of the options A and B do not change the amino aids being made. Hence, the changes in options A ans B will be less damaging then the option C.

Answer 4:

In the field of genetics, a stop codon can be described as a signal which stops the translation. It is a three nucleotide sequence which is recognized as a terminator.

If stop codon is not present at the right place, then the process of translation will not terminate at the right place and wrong proteins will be made.

How long does it take to bleed out from a stab wound?.
vaieri [72.5K]

Explanation:

Consider a stab wound in upper abdomen which has pierced through upper/ventral wall of stomach. This is what medically called as gastric perforation and requires emergency surgical management within 4 to 12 hours of injury. If left unattended the person will develope distension of abdomen with vomitting within 4 to 6 hrs, fever within 12 hrs, all because of infection spreading to rest of abdomen ( medically called Peritonitis). If no surgery is undertaken the person will die due to sepsis within 24 to 48 hrs.

Situation 2: stab would injuring major vessel or even liver will pool blood in abdomen ( medically Hemoperitonium) will further worsen the situation and wld need more intensive management. If not treated properly such person can die within 6 to 12 hrs due to hypovoluemic shock.
