Which of the following is an example of specific immunity?

Answers

Answer:

Immunity to Small Pox

Explanation:

Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.

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

Answers

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

The proper function of the stomates on the leaf (and therefore, the function of water and CO2 movement) is influenced most by which element

Answers

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​

Answers

                                       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.).

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?

Answers

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.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.

What genetic explanation can you provide as to why the girl
suffers from hemophilia?

Answers

answer:

So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.

Explanation:

A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.

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.

It was stuffed, of course, but quite imposing nonetheless. This grand specimen was nearly two feet long with brown, white and rusty red feathers. Its yellow eyes were large and perfectly round, giving it a wise look. Its talons were thick and sharp, and on its brow two curved feathers stuck up, looking just like two horns. I got the impression that this bird was a great hunter.Of the 145 species of owl, the great horned is the largest. Owls live in most parts of the world, ranging from tropical to subarctic climates. The elf owl is the smallest at only six inches, but no matter what their size, all owls are good hunters. They hunt under cover of night, so their prey can't see them. Unlike other birds, owls have large, soft feathers that allow them to fly without making noise, which also makes them good predators. Farmers like owls because they keep pests such as mice, voles, rats and even rabbits from their crops and stores of grain. And they have hearty appetites. Henry Williamson, a farmer in England, had eleven barn owls on his farm. He kept careful watch on their hunting habits and was astounded to find that together they ate 150 mice each night! While farmers may be grateful to owls, owners of cats and small dogs should beware: owls have been known to pluck up small pets that unknowingly wander into the birds' hunting zones.Select the correct answer.Why might it be difficult to keep an owl as a pet?A. Owls need to eat a lot of fresh mice daily.B. Owl feathers need a great deal of care.C. Owls need to live in subarctic temperatures.D. Owls need to sleep during the day.
