How does the CF gene affects the cell membrane?
Answer:
Normal Function. The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator. This protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.

What are the components of a multicellular organism?
Answer:
Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells.
Answer:
Because the first multicellular organisms were simple, soft organisms lacking bone, shell or other hard body parts.

The sperm and the ovum are called haploid (as they have only 23 chromosomes) which is half the number of chromosomes seen in all the other human body cells. What is the significance behind the maintenance of this special chromosomal number in the male and female gametes?
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.

Sickle cell anemia is carried on the recessive allele. Normal is dominant. Mary is a carrier for sickle cell and Mike is normal (but not a carrier).
A. What are the chances of Mary and Mike having a sickle cell child?
B. What are the chances of them having a child who is a carrier?
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%.

Why are leaves necessary for a plant?
Answer:
PLEASE MARK AS BRAINLIEST!!
Explanation:
Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen.

During winter's freezing temperatures, some plants can remove water from their cells to reduce the amount of water that will freeze inside them. Why would plants need to do this
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

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.

The proper function of the stomates on the leaf (and therefore, the function of water and CO2 movement) is influenced most by which element
Answer:
Sunlight.
Explanation:
Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.

what is sustainable development
Answer and Explanation
__________________________________________________________
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.).

What is Electron Transport Chain and what happens in that stage of cellular respiration?
The electron transport chain (ETC) is the final step of cellular respiration and takes place in the mitochondrion.
The final step in cellular respiration is the electron transport chain. This is sometimes abbreviated as ETC. ETC needs oxygen, which means aerobic process. It occurs at the edges of the inner lining of mitochondria. These handles are called cristae.
Determine the temperature of the bar on the fahrenheit scale.
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
