Which characteristics describe the genetic code of humans? Select three options.

can help in development of effective medications
can only help understand human genetics
can help explain genetic diseases
composed of about 19,000 genes
composed of 23 chromosomes

Answer:

can help explain genetic diseases, composed of about 19,000 genes, can help in development of effective medications

Explanation:

1) Certain diseases, like hemophilia, are caused by genetic differences

2) just a fact, no explanation

3) Different people have different genetic codes, which code for different receptors. Certain people may have more/less receptors for a medicine, so it determines dosage.

Bird feeders can be found in backyards around the globe. Some people like to watch as the birds flock to the feeders and peck at the seeds. Others may like the idea that they are offering a service by feeding the local birds in their neighborhood. But do bird feeders help native populations of birds? A recent study suggests that bird feeders may do more harm than good by increasing competition for food.

A team of scientists in New Zealand observed that bird feeders may be attracting more invasive, or non-native, birds. They conducted an experiment to see if this observation could be supported with data. The scientists set up 23 bird feeder locations scattered around urban areas. Food in the form of mixed bird seed and bread was offered daily at 11 experiment locations. "Twelve locations were left alone, without food, to serve as a control group. The number of birds that visited each location was counted daily. The study went on for almost two years. After analyzing the data, scientists discovered that the 11 experimental bird feeders attracted two to three times the number of invasive species of birds as the control group feeders. The control group feeders had approximately equal numbers of native and invasive birds visit them. The team of scientists noted that the increase in invasive species may have been due to the food choices that were offered at each feeder. Native birds typically eat fruit, nectar, and insects. Invasive birds were more attracted to the mixed bird seed and bread. The data supported the conclusion that backyard bird feeders were not helping native bird populations and suggested that invasive species are pushing out native species in competition for food.

The team of scientists also noted that they are not suggesting that people stop feeding the birds. They just want people to be aware of the types of food they offer and how often they fill the feeders. Making better choices in backyard feedings may help increase the number of local birds that visit while decreasing visits from invasive species.

Conducting backyard bird feeder experiments is a great way to see which local birds and which invasive birds are in your neighborhood. The more you know about the local bird populations and their food preferences, the better equipped you are to support them in a more positive way.

Question- How did the backyard bird feeders in the article increase competition in that ecosystem? (yes its a lot but 20 points and brainliest to the best answer!)

Use the simple food chain below to answer the question about energy transformations.


It takes energy to live; therefore, when the owl eats the rat, the owl does not receive 100% of all the energy the rat consumed during its lifetime. What form of energy is “lost” in the ecosystem?
Thermal energy
Light energy
Electrical energy
Nuclear energy

Help!

Describe the flow of energy in this food chain. Be sure to use the names of the organisms and what role they serve in the food chain (producer, consumer, or decomposer). If an organism is a consumer, identify whether it is an herbivore, carnivore, or omnivore.

URGENT! Will mark Brainliest if correct! No fake answers please!

9. Sickle cell anemia is a genetic disease that affects the red blood cells. Your red blood cells are typically donut shaped and have the job of carrying oxygen around your body. In people with sickle cell anemia, the blood cells become crescent-shaped and are thick and sticky. They are not as able to carry oxygen, and can even get clogged in the blood vessels blocking the flow of blood, and therefore oxygen to organs, causing pain and organ damage.

Sickle cell is caused by a genetic mutation that changes a single glutamic acid to valine in the 6th amino acid position.

A) Examine the codon chart provided above (for #s 3-5), and determine what mutation likely occurred to cause the change from glutamic acid (GLU) to valine (VAL). To help get you started, it is helpful to know that a person with NO sickle cell at amino acid #6 has a DNA code of CTC. (4pts)

Normal RNA: ____________, Normal amino acid made: ___________

Mutated RNA: ___________, Mutated amino acid made: ___________

What type of mutation is this? ________________________________
