????????????????????????????????????????? What is the answer to number 2 and 3 I’m really confused

Answer:

All research questions should be:

Focused on a single problem or issue.

Researchable using primary and/or secondary sources.

Feasible to answer within the timeframe and practical constraints.

Specific enough to answer thoroughly.

Complex enough to develop the answer over the space of a paper or thesis.Choose an interesting general topic.

Most professional researchers focus on topics they are genuinely interested in studying.  

Consider your audience.  

Explanation:

A research question is the question around which you center your research. It should be: clear: it provides enough specifics that one's audience can easily understand its purpose without needing additional explanation.

Hope this helped!!!

It makes sense because Dinosaurs existed during that era and became extinct after that era.

Answer:

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Given that:

The allele → R = Red beetles

The allele → B = Blue beetles

Since the gene color shows a codominant allele

The Red Beetle = RR

The blue beetles will be = BB

The heterozygous beetle will be = RB

∴

The punnet square showing the crossing of RB × RR is:

                R                   B

R                RR               RB

R                RR               RB

The result shows that we have two red beetles and two heterozygous beetles.

Hence;

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Animals, including humans, derive chemical energy from their food to support their metabolism, including their muscular activity.

The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.

Cells release energy from nutrients through the process of respiration. The majority of the time, glucose has already been produced from the food.

Because they work quickly and provide energy as soon as they are taken, carbohydrates—which have 4 kcal per gram—are the foods that are used as an energy source the most frequently.

Therefore, food give you energy and help you feel satisfied after eating.

Answer:    

Enters through the gills and tubed feet.

Explanation:

The oxygen obtained by a Purple Sea Urchin is dissolved in water.  Oxygen enters through the gills and tubed feet. When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through the body (through the canals).

Any Questions?

Oxygen enters the sea urchin's system through the respiratory system, which is through the water vascular system, as the echinoderms have a significant type of system that helps them take the oxygen from the water.

The water vascular system is seen in the phylum of the echinodermata, which is essentially a network of canals and tube feet that run throughout the urchin's body, and the tube feet are helpful for the attachment to the surface and for the respiration. When the tube feet are extended, oxygen from the water diffuses across the walls of the tube feet and into the urchin's body, while carbon dioxide is released into the water.

Hence, oxygen enters the sea urchin's system through the respiratory system, which is through the water vascular system, as the echinoderms have a significant type of system that helps them take the oxygen from the water.
