What cells combine to make the first eukaryotic cell?

Answers

Explanation:

Eu" means "true," and eukaryotes have DNA arranged in chromosomes and encased in a nucleus. Fossil evidence indicates that prokaryotic cells first existed on the earth, prior to the arrival of the eukaryotes.

eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

If two air masses have the same relative humidity of 60 %, which one contains more water vapor?

a. The one with the higher temperature
b. Both would have the same amount
c. The one with higher relative humidity
d. The one with the lower temperature

Answers

b. Both would have the same amount

Option b. Both contain a similar amount.

Given that,

The two masses should have a similar relative humidity of 60%.We need to find out which have more water vapor.

Based on the above information, we can say that since both two masses contain the same humidity i.e. 60% so it means that they have the same amount.

Therefore the option b is correct.

How many atoms of carbon, hydrogen, and oxygen are there in the reactants of photosynthesis?

Answers

Answer:

The reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms. IN HYDROGEN ATOMS  It takes six atoms of carbon (C) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6). These atoms come from carbon dioxide (CO2) and water (H2O). IN OXGYEN It takes six atoms of carbon (C), six atoms of oxygen (O) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6).

In photosynthesis, the reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms.

What do you mean by photosynthesis?

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

radium in an element found in group 2 and period 7. in a normal radium atom, how many energy levels contain at least one atom?

A. 1 B.6 C.7 D.8

Answers

Answer:

the answer is d

Explanation:

In a normal radium atom, there are 7 energy levels.

The periodic table is arranged in groups and periods. The elements in a group have the same number of valence electrons while the elements in the same period have the same number of energy levels.

Radium is an element in period 7. The fact that it is in period 7 implies that it has 7 shells or energy levels. Hence, in a normal radium atom, there are 7 energy levels, each containing electrons.

In snapdragon the gene that affects flower color has two alleles: red (R) and white (W). In heterozygous individuals, the phenotype is pink. If two pink flowers were crossed what would be the probability of a pink offspring?

A. 25%

B. 50%

C. 75%

D. 100%

Answers

Answer:

The correct answer is - 50%

Explanation:

In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:

      R     W

R    RR   RW

W   RW    WW

here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%
