would they be occurring in
abundance and what for?
.................

Answers

Answer 1

Answer: yes, many different kinds

Explanation: bacteria are everywhere and so will be found in aquaria. Aquarium health is dependent on bacteria. Fish excrete ammonia which is toxic. Bacteria such as Nitrosomonas and Nitrococcus convert ammonia to nitrite, and Nitrobacter converts nitrite to nitrate which is relatively harmless. Bacteria such as Pseudomonas stutzeri and Bacillus subtilis remove nitrate and organic waste. There are also bacteria in fish intestines, and other bacteria that can cause fish diseases or create undesirable conditions such as Pseudomonas fluorescens, Vibrio, Flexibacter or Aeromonas and anaerobes that reduce sulphates to hydrogen sulphide.

What are the nonliving components which are essential for the growth of the body?

Carbohydrates and lipids are the non living components which are essential for the growth of the body. Carbohydrates has been defined as the biomolecule that contains carbon, hydrogen. and oxygen in a ratio of 2:1. Carbohydrates were the main source of the energy for body and they work as fuel or power for the brain, kidneys as well as central nervous system and for the muscles of heart. is the basic formula for all carbohydrates.

Lipid has been defined as an organic compound which has unable to dissolve in the water. The example of the lipid are oils, waxes, hormones, and fats. The main function of lipid has to maintain the structure or components of the cell membranes, storage site of energy, and important molecule for cell signaling.

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.

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%

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.

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.
