When people receive organ transplants, they often need to take medications that decrease immune responses because * 2 points D.
Oksana_A [137]

Answer:

The correct answer is A. transplanted organs contain antigens that can trigger white blood cell activity

Explanation:

The body's immune system is designed to seek out and destroy any foreign object it finds in the body, such as a cold or flu virus - or a transplanted organ. The process of destruction of the transplanted organ is called rejection.Immunosuppressive drugs will be provided to prevent your immune system from damaging the transplanted organ. Organ transplants require the use of immunosuppressive drugs capable of controlling the immune response triggered by the presence of antigens foreign to the body itself. The group of immunosuppressants is made up of drugs indicated both in the prevention of rejection of the transplanted organ and in its reversal.

Can someone make me report for bees and flowers I know what to do but don't know how to make it into 300 words
dybincka [34]

Answer:

Bees and flowering plants have a mutualistic relationship where both species benefit.

Explanation:

Bees play a keystone role in the agricultural production and the beauty of our world through the pollination of fruits, vegetables, nuts, and flowers. The disruption of natural habitats leading to lack of "bee flowers,"

Once they reach adulthood, most living things take care of themselves and sometimes their offspring. However, certain plants and animals have developed helpful relationships with living things outside their own species. Scientists call such relationships "mutualistic relationships" because both organisms benefit from the arrangement. One of the most famous mutualistic relationships in nature is the relationship between bees and flowering plants. This relationship allows bees to feed their colonies and plants to reproduce

Bees and flowering plants have a mutualistic relationship where both species benefit. Flowers provide bees with nectar and pollen, which worker bees collect to feed their entire colonies. Bees provide flowers with the means to reproduce, by spreading pollen from flower to flower in a process called pollination. Without pollination, plants cannot create seeds.

How Bees Benefit From Flowers

Flowers benefit bees by providing them with all the food their colonies need, to survive. With the exception of a few species, bees are social insects that live in colonies of between 10,000 and 60,000 individuals. How many bees live in a single colony depends on factors such as the bees' species, the weather in their environment and how much food is available.

Bees feed on the nectar and pollen of flowers. Nectar is a sweet liquid substance that flowers produce specifically to attract bees, birds and other animals. Pollen is a powder that contains the male genetic material of flowering plants. Worker bees (bees whose job is to collect food for the colony) land on flowers and drink their nectar. This nectar is stored in a pouch-like internal structure called the crop. In the process of doing this, bees become covered in pollen. The pollen sticks to the bee's hairy legs and body. Some bee species even have sack-like structures on their legs for collecting pollen, called pollen baskets.

After collecting nectar and pollen from many different flowers, bees fly back to their colonies. They regurgitate nectar, mixed with enzymes, and expose the mixture to the air for several days, creating honey. This honey is used to feed the colony. Pollen is mixed with nectar to form a protein-rich substance called beebread. Beebread is primarily used to feed young developing bees, called larvae.

How Flowers Benefit From Bees

Bees benefit flowering plants by helping the plants reproduce, via pollination. Because plants cannot seek out mates the way animals do, they must rely on outside agents, called vectors, to move their genetic material from one plant to another. Such vectors include bees, certain birds and wind.

Flowering plants carry the male portion of their genetic material in their pollen. When bees fly from one flower to another, pollen is spread from plant to plant. If pollen from one flower is able to reach another flower of the same species, then that plant will be able to form seeds and reproduce.

Without bees, pollination and reproduction would be practically impossible for some plant species. This makes bees a vital part of every ecosystem they inhabit. Humans also greatly benefit from the pollination bees provide. Bees' work allows humans to enjoy fruits, vegetables and other plant products that would not be available otherwise.

What property of DNA makes it possible for a probe to find a single-stranded DNA target gene?
Galina-37 [17]

Answer:

base pairing property

Explanation:

every dna/rna base, a c g t and u, has only one possible pairing partner, so if the strand is open on one side (single strand), the opposite side can be inferred because only one sequence will match the existing strand's base sequence. the property is usually called base pairing property
