16. In which of the following situations are the phenotypes of F2 offspring expected to follow
the ratio of 9:3:3:1?
a. monohybrid cross for two unlinked traits
b. a monohybrid cross for two closely linked traits
c. a dihybrid cross for two unlinked traits
d. a dihybrid cross for two closely linked traits​

Answers

Answer 1

Answer:

C

Explanation:

The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a dihybrid for two unlinked traits.

There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.

A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.

Hence, the correct option is C.

than a plant based diet.
help I need this by 1:45 :’)

Answers

Plant-based diets provide well-established physical and environmental health benefits. These benefits stem in part from the degree of restriction of animal-derived foods. Historically, meat and other animal-derived proteins have been viewed as an integral component of athletes’ diets, leading some to question the adequacy of vegetarian or vegan diets for supporting athletic performance. The purpose of this review is to examine the impact of plant-based diets on human physical health, environmental sustainability, and exercise performance capacity. Based on currently available literature, it is unlikely that plant-based diets provide advantages, but do not suffer from disadvantages, compared to omnivorous diets for strength, anaerobic, or aerobic exercise performance.

4. Compare and Contrast Which kind of plant–a sun plant or a shade plant-has a
higher rate of photosynthesis when light intensity is below 200 umol photons/mº/s?
When light intensity is above 400 umol photons/mº/s?

Answers

Answer:

Below 200 umol photons/mº/s, shade plant grow best.

Above 400 umol photons/mº/s, sun plant grow best.

Explanation:

A shade plant has a  higher rate of photosynthesis when light intensity is present below 200 umol photons/mº/s because shade plants needs low light intensity for higher photosynthesis while on the other hand, a sun plant has a  higher rate of photosynthesis when light intensity is above 400 umol photons/mº/s because it requires high intensity of light for photosynthesis if other factors are also present in large amount such as water and nutrients in the soil.

4.
Mercury and Venus
Submit Answer

Answers

Answer:

1, uranus and neptune

Explanation:

i just did it

Based on the diagram above, the two planets having diameters that most closely resemble this comparison are: 1.  Uranus and Neptune.

A solar system is an astronomical system which comprises both the inner and outer planets alongside celestial bodies such as a Moon, that are typically in orbit (traveling) around the Sun in slightly elliptical orbits..  

Basically, the nine (9) planets that are found in the solar system orbiting around the sun include;

Mercury. Venus. Earth. Mars.Jupiter.Saturn.Uranus.Neptune.Pluto.

Generally, the planets found in the solar system vary considerably in terms of shape and size as shown below:

1.  Uranus and Neptune: the mean diameter of Uranus is 50,724 km (31,518.43 mi) while that of Neptune is 49,244 km (30598.8 mi).

2. Jupiter and Saturn: the mean diameter of Jupiter is 142,984 km (88,846 mi) while that of Saturn is 120,536 km (74897.6 mi).

3. Earth and Mars: the mean diameter of Earth is 12,756 km (7926 mi) while that of Mars is 6779 km (4212.275 mi).

4. Mercury and Venus: the mean diameter of Mercury is 4,879 km (3031.67 mi) while that of Venus is 12,104 km (7521 mi).

From the above data on diameter, we can deduce that both Uranus and Neptune are mostly related in terms of size as depicted in the diagram, by using two (2) circles of equal sizes.

Joe is experimenting to determine which liquid will cause bean plants to grow faster. He watered the plants with equal amounts of liquid and measured their height every other day. The plants are in the same pots with different soils and placed in the same location. Will Joe be able to obtain reliable data to write a supported conclusion?
Yes, because he is only observing the height of the plant.
Yes, because he is consistent with watering the plants.
No, because he used different soils.
No, because he uses only one type of plant.

Answer:

No, because he used different soils.

Explanation:

which liquid will cause bean plants to grow faster.

He watered the plants with equal amounts of liquid and measured their height every other day.

Answers

Answer:

scientists can determine the evolutionary relationships between different organisms by comparing their appearances, figure, and body internal and external structures.

Explanation:

Scientists utilize DNA to evaluate evolutionary relationships, along with resemblance in early development and bone structure.

What are evolutionary relationships?

Organisms with similar physical characteristics and genetic sequences are more strongly linked than those that do not.

Homologous structures are components that overlap both anatomically and genetically; the similarities stem from shared evolutionary paths.

Thus, scientists utilize DNA to evaluate evolutionary relationships, along with resemblance in early development and bone structure.

All the above.

Answers

Organisms mainly use the molecules glucose and ATP for energy. Glucose is a compact, stable form of energy that is carried in the blood and taken up by cells. ATP contains less energy and is used to power cell processes. The flow of energy through living things begins with photosynthesis, which creates glucose.
Answer:
ATP

Explanation: as the other person said they mainly use glucose or ATP for energy. Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
