A graph of a bird population with different-sized beaks is shown below.After a several-year drought, smaller seeds became scarce, but drought-resistant trees continued producing larger seeds. What graph would best predict the change in beak length of the bird population?
Research Problem: You come across three new species of primates that all cohabitate the same forested area. No one has looked at the behavior of these monkeys before so there is lot to discover about each species. You and a fellow researcher are interested in describing the diet of each of these species (Do they eat fruits? Leaves? Insects? Tree-sap? A combination of sorts?). Your fellow researcher has determined that her hypothesis is that two of the monkeys primarily eat fruit, while one of the monkey species eats tree sap.

Fructose‑2,6‑bisphosphate is a regulator of both glycolysis and gluconeogenesis for the phosphofructokinase reaction of glycolysis and the fructose‑1,6‑bisphosphatase reaction of gluconeogenesis. In turn, the concentration of fructose‑2,6‑bisphosphate is regulated by many hormones, second messengers, and enzymes. Classify each condition according to its effect on glycolysis and gluconeogenesis Activates glycolysis and inhibits gluconeogenesis Activates gluconeogenesis and inhibits glycolysis

Answers

Answer: Activates glycolysis and inhibits gluconeogenesis

Explanation:

Fructose‑2,6‑bisphosphate coordinates glucose breakdown in glycolysis generates by modulating the action of phosphofructokinase 1 and at the same time inhibits gluconeogenesis.

In asexual reproduction, only one parent contributes to offspring. The offspring aregenetically identical to the parent and with one another. The process involves mitosis but not

With sexual reproduction, you can have diversity it the offspring
With asexual reproduction, the offspring is an exact replica of the parent

PLEASE HELPP QWQIn what direction and with how much not force will the satellite move?

The net force is 0 N, so the satellite will not move.

The net force is to the right at 1500 N.

The net is to the left at 1000 N.

The net is to the left at 500 N.

Answers

The net force with which the satellite move is 500 Newtonsand the satellite moves in the left direction. Thus, the correct option is D.

What is the net force?

The net force on an object can be defined as the combined effect of the sum of all the forces such as pushing and pulling forces which are actually acting on the object. If all the forces which are pushing or pulling on an object are not balanced, then in this case a net force acts on that object which then makes the object to accelerate in the direction of the net force applied.

Net force = Sum of all the applied forces

Since, here the forces applied are in different directions.

Net force = 1000 N (towards left) - 500 N (towards right)

Net force = 500 N (towards left)

The net force has a magnitude of 500 Newtons and it is in the left direction because 1000 N is more than 500 N.

Therefore, the correct option is D.

Answer: D

Explanation:

Some Eukaryotic cells have internal structures that are able to use photosynthesis to convert light energy into chemical energy (as bonds in sugars). Why is this capability not found in all Eukaryotes?

Answers

Answer:

The endosymbiotic event that brought chloroplast in eukaryotic cells happened after the lineage delivered.

Explanation:

The endosymbiotic theory says that the ancestral cell gains the ability of photosynthesis when it engulfed a photosynthetic bacteria and this bacteria remained in a symbiotic relationship with the ancestral cell and evolved as chloroplast in plants that can perform photosynthesis.

All the eukaryotes do not have this internal structure like chloroplast because this endosymbiotic event must be happened after the divergence of the lineage into different groups. Therefore plant cells have chloroplast and animals cell do not have.

The question is incomplete as it does not have the options which are provided in the attached picture.

Answer:

Option-B

Explanation:

The theory of the endosymbiotic origin of eukaryotes proposed that the organelles like the chloroplast and mitochondria are originated when the proto-eukaryotes engulfed the prokaryotic cells.

The chloroplast was formed in some eukaryotes instead of others as the proto eukaryotes diverged into many lineages before the origin of the chloroplast in them. One of the lineages engulfed the chloroplast and become photosynthetic organism but rest of the proto eukaryotic lineage did no engulfed the bacteria and did not possess the chloroplast.

Thus, Option-B is the correct answer.

A dedicated surgery suite must be used for which type of surgery?

Answers

Major survival surgery on non-rodent mammals

Major survival surgery in non-rodent mammals must be conducted in dedicated facilities. Major survivalsurgery penetrates and exposes a body cavity, produces substantial impairment of physical or physiologicfunctions, orinvolves extensive tissue dissection ortransection (e.g., laparotomy, thoracotomy, jointreplacement, and limb amputation). The ultimate decision to classify a surgery as major or minor will bemade by the IACUC. Investigators cannot perform major survival surgery in non-rodent mammals in theirown laboratories, but must make use of IACUC approved survival surgery suites that meet federal standards.Major operative procedures on non-rodents will be conducted only in facilities intended forthat purposewhich shall be operated and maintained under aseptic conditions. Dedicated surgery suites must be1approved by the IACUC priorto use and inspected semi-annually. Contact the IACUC office for additionaldetails regarding dedicated surgical suites and major versus minor surgical classifications.
