What are some examples of non-native species that have been Introduced to and thrive in Los Angeles increasing the overall "biodiversity" because of human activity?

Answers

The House Sparrow was introduced to North America from Europe. It is not really a sparrow but a European weaver-finch. It is highly successful, tends to follow human habitation, thrives in agricultural areas, and does not damage the local ecosystem. I would rate it a neutral. Bird of the Day: A Sparrow that's not a Sparrow, and a Successful Immigrant

The reintroduction of wolves into Yellowstone has had a positive effect on the ecosystem there. Wolf Reintroduction Changes Ecosystem

Horses were also introduced from Europe to North America and seem to have been neutral toward the ecosystem (unless you are a cattle rancher). They could be considered a reintroduction since they did evolve in North America also but just died out in the past.

Wild turkeys were introduced to the Western states from its native location in the Eastern US. They have been successful and effect on the ecosystem seems at worst neutral.

Two introductions that we regard as very beneficial animals, the earthworm and the European honeybee had negative effects on the native North American ecosystem, but very positive effects on those plants that the settling Europeans were trying to grow. The earthworm had been killed off the ice age in the Northeast and was introduced via the ballast from ships. Earthworms ground through leaf litter that the trees depended on and resulted in sparser forests. Honeybees were deliberate introductions. The native bees were few and favored only a few plants. The European honeybee was enormously fertile and liked pretty much all flowering plants making it a major league pollinator. My source for this information earthworms and honeybees is America, Found and Lost

Human cells have two sets of DNA in each cell. Thus, the correct option is A.

What is DNA?

DNA stands for Deoxyribonucleic acid. It is considered the genetic material of most organisms. It consists of base pairs like adenine, thymine, guanine, and cytosine.

Human cells have two sets of DNA in each cell, one came from the paternal side while the other came from the maternal side.

Therefore, it is well described above.

HELP ME MAKE THIS ESSAY BETTERStructure and Function of MicroscopesA microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. There are several types of microscopes but in this essay, we will be discussing the compound light microscope, the transmission electron microscope, and the scanning electron microscope. And we will be comparing its structure and function.From its name compound light microscope uses light as its radiation source with a wavelength that reaches from 400 to 700 nm though the Transmission electron microscope uses electrons as its radiation source, the scanning electron microscope uses electrons as well which wavelength reaches 0.005 nm.For the lens, the compound light microscope uses glass that is have its maximum resolution of 200 nm and can view colored images with an eyepiece powered 10x and 3 or 4 objective lenses that are power can be (4x, 10x, 40x) power. both transmission electron microscope and scanning electron microscope uses Electromagnetic as their lens although transmission electron microscope lens maximum resolution is 1 nm, and its maximum magnification power is 250 000x with a monogram view and scanning electron microscope lens maximum resolution is 10 nm and its maximum magnification power is 100 000x with a monogram view as well.For the specimen, the compound light microscope supports both living and non-living specimens. The transmission electron microscope and the scanning electron microscope both support only non-living specimens although the transmission electron microscope supports it on a small copper grid in a vacuum, and the scanning electron microscope supports it on in a metal disc in a vacuum.In the end, all microscopes are useful without microscopes no medicines would be found because scientists would not know how to treat the micro viruses and bacteria, and we could not explore and discover micro-organisms around us that we cannot see with our naked eye.

How can using a dam as a source of freshwater also harm wildlife?
A. Dams help control floodwaters.
B. Dams provide drinking water.
C. Dams displace existing habitats.
Ο Ο
D. Dams provide water recreation.

Answers

Answer:

c

Explanation:

because its the only one that would be hurting wild life.

Using a dam as a source of freshwater can harm wildlife by displacing existing habitats. Therefore, option (C) is correct.

What are the negative impacts of dams?

Dams often require the creation of reservoirs, which can submerge large areas of land and alter the natural flow of rivers and streams. This can lead to the loss of important habitats for fish, mammals, and other wildlife that rely on rivers and streams for food, shelter, and reproduction.

In addition, changes in water temperature, dissolved oxygen levels, and water flow can negatively impact aquatic ecosystems downstream from the dam.

These impacts can be mitigated through careful planning and management, such as the creation of fish ladders and other structures to help fish navigate past the dam, and the release of water at appropriate times to mimic natural flow patterns.

In wolves, gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). The genes that control these traits are located on different chromosomes. The alpha male of the pack has the dominant phenotype for both traits and is heterozygous for both traits. The alpha female has brown eyes and a black coat; she is heterozygous for eye color. Which option represents gametes that would be made by the alpha female

Answers

The combination of gametes that will be produced by the Alpha female is Bg, Bg, bg and bg.

According to this question, two genes coding for eye color and coat color in wolves are involved. Gray coat color (G) is dominant to black coat color (g) while brown eyes (B) are dominant to blue eyes (b).

The alpha female of the pack is said to have a brown eyes and a black coat (gg) but she is heterozygous for eye color (Bb). This means that she posseses the following genotype: Bbgg.

According to Mendel in his law of independent assortment, alleles of a gene will segregate into gametes independently of one another.

This means that the alpha female with genotype (Bbgg) will segregate into the following combinations of gametes: Bg, Bg, bg and bg.

Choose 1 answer:


A) The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes.


B) The pairs are non-homologous chromosomes that contain different sets of genes.


C) The pairs are homologous chromosomes that have identical copies of every gene.

Answers

Answer: A

i have no idea why

The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes. The correct option is A.

What are homologous chromosomes?

Among a pair of chromosomes with the very same gene sequence, loci, chromosomal size, and centromere location is referred to as a homologous chromosome.

One paternal and one maternal chromosome make up a homologous pair. In humans, the nucleus of a somatic cell contains 46 chromosomes.

Homologous chromosomes differ from sister chromatids because they are not identical and do not emanates from the same organism.

Sister chromatids are identical, side-by-side duplicates of each other that form as a result of DNA replication.

Homologous chromosomes do not pair together during mitosis. Homologous chromosomes line up end-to-end in mitosis so that when the cells divide, each daughter cell receives a sister chromatid from both members of the homologous pair.

Thus, the correct option is A.
