What is the energy source that allows photosynthesis to occur?

Answers

Answer:

[tex]\boxed {\boxed {\sf The \ sun }}[/tex]

Explanation:

Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".

This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.

This process occurs because of the sun. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.

The table below shows the initial and final masses of a radioactive material whose half-life is 15 years.

Initial mass (in kilograms): 0.8
Final mass (in kilograms): 0.05

Based on the table, which of these conclusions is correct?

A.) The material decayed from 0.8 kilograms to 0.05 kilogram in 60 years.
B.) The material decayed from 0.8 kilograms to 0.05 kilogram in 30 years.
C.)The mass of the material was 0.1 kilograms after four half lives.
D.) The mass of the material was 0.1 kilograms after five half lives.

Answers

Answer:

A

Explanation:

1 half-life = .4 kg = 15 years

2 half-life = .2 kg = 30 years

3 half-life = .1 kg = 45 years

4 half-life = .05 kg = 60 years

Answer:

A

Explanation:

Initial mass is 8. The half-life is 15 years.

1st half life=.8/2=.4

2nd half life=.4/2=.2

3rd half life=.2/2=.1

4th half life=.1/2=.05

For each half life that it took it to go from .8 to 0.05, you add 15 years since that is the half life of the substance. 4*15=60.

So, the answer is A. The material decayed from 0.8 kilograms to 0.05 kilogram in 60 years.

2.
Jupiter and Saturn

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.

Explanation:

Two offspring from same parents can have different phenotypes. How is this possible?​

Answers

Answer:

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

Explanation:

Overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.

What is heterozygote?

Heterozygote is defined as a person, animal, or other thing possessing a pair of different alleles of a specific gene, one of which is dominant and the other recessive. One normal allele and one mutated allele, or two distinct mutated alleles, can make up a heterozygous genotype.

The explanation is connected to the fact that each parent has two different gene pools. Furthermore, only 50 percent of each parent's DNA is transferred to their offspring. and that the portion that is passed down is random. Every child has a unique set of genes thanks to the interaction of all these influences.

Thus, overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.

Answers

Answer:

Due to agnathous, no paired fins and scales.

Explanation:

Pteromyzon fish is different from scolidon and labeo fishes because Pteromyzon fish is not a true fish. The main reason for this is that Pteromyzon fish is agnathous means having no jaws and it doesn't have paired fins and scales on their body while all these features are present on the body of  scolidon and labeo fishes so we can conclude from this discussion that Pteromyzon fish is different from scolidon and labeo fishes.
