Answer:

C

Explanation:

ight provides the energy for breaking apart sugars into small molecules. ... They absorb sunlight and transfer the energy to electrons. They form ATP as hydrogen ions cross the thylakoid membrane

Light provides the energy for making small molecules into sugars.

The correct option is B.

Photosynthesis is the process, by which plants make their food.

The process of photosynthesis is

carbon dioxide and water combined with the help of light to produce glucose and oxygen.

The light helps in the synthesis of glucose from water and carbon dioxide.

Thus, the correct option is B. Light provides the energy for making small molecules into sugars.

Answer:

During the process of meiosis(The process of cell division through which the germ cells such as the reproductive cells are formed), the sex cells produced are haploids (have only 23 chromosomes). This is significant as during the process of fertilization, the nucleus of the sperm (containing 23 chromosomes) and the nucleus of an egg (containing 23 chromosomes too) fuse, hence, retaining the original number of chromosomes in the zygote formed. i.e 46 chromosomes.

The best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.

Prokaryotic cells are single-celled microorganisms known to be  earliest on earth.Eukaroyotic cell have a nucleus enclosed within the nuclear membrane and form large and complex organism.

Difference between unicellular and multicellular.

The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.

Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.

In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.

Therefore,the best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

Answer:

The expansion of excess water as it turns to ice inside the cells would break the cells apart

Explanation:

We know that water expands anomalously. It expands between 4- 0°C.

Hence water expands upon freezing. Ice has more volume than liquid water and takes up more space in plant cells.

The expansion of excess water as it turns to ice inside the cells would break the cells apart

__________________________________________________________

According to UNESCO,

Sustainable development is the overarching paradigm of the United Nations. The concept of sustainable development was described by the 1987 Bruntland Commission Report as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”  

 __________________________________________________________

There are four dimensions to sustainable development – society, environment, culture, and economy – which are intertwined, not separate. Sustainability is a paradigm for thinking about the future in which environmental, societal, and economic considerations are balanced in the pursuit of improved quality of life. For example, a prosperous society relies on a healthy environment to provide food and resources, safe drinking water, and clean air for its citizens.  

 __________________________________________________________

One might ask, what is the difference between sustainable development and sustainability? Sustainability is often thought of as a long-term goal (i.e. a more sustainable world), while sustainable development refers to the many processes and pathways to achieve it (e.g. sustainable agriculture and forestry, sustainable production and consumption, good government, research and technology transfer, education and training, etc.).

Answer:

A. 0

B. 1/2 or 50%

Explanation:

Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.

Mary, a carrier would have the genotype Ss.

Mike, a perfectly normal person would have the genotype SS.

If both Mary and Mike marry:

                     Ss     x     SS

offspring: SS    SS    Ss    Ss

(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.

(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.

Answer:  

Determining bar temperature on Fahrenheit scale -

The temperature of the bar is given as 50 degrees Celsius.

If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.

We know

C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.

Now,

50/5 = (F-32) / 9

Or, (F-32) / 9 = 10

Or, F-32 = 90

Or, F = 90 + 32

Or, F = 112 degrees Fahrenheit.

That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit
