what are the negative effects of endangered species?
Answer:
there are several causes of negative effects when there are endangered species but the number one reaseon is if they die it slowly kills the ecosystem one animal at a time if that animal is part of a food system of life chain.
Explanation:
i hope this helps your welcome boos :) <3
When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.

A eukaryotic cell has 6 chromosomes, explain what you would get at the end meiosis.
Answer:
If a eukaryotic cell has 6 chromosomes, the end result after meiosis is two daughter cells with 3 chromosomes each.
Explanation:
Meiosis is the process of cell division by which sex cells or gametes are formed. It is a mechanism of reductive division, since the chromosomal charge of a eukaryotic cell —diploid— is reduced by half, that is, haploid cells are obtained.
A diploid eukaryotic cell with 3 pairs (6) of chromosomes, after meiosis produces two haploid daughter cells, with 3 chromosomes each.
This process of reductional division, where the gametes are obtained, aims to ensure that when the gametes of each parent join together they form a diploid cell, the zygote.

In modern taxonomy, species are the most
taxa.
broad
complex
specific
Species are the most specific in modern taxonomy.
Taxonomy is defined as the scientific method of classifying, identifying and naming living organisms.
In the hierarchy of living organisms, the largest group of organisms is the Kingdom. This is followed by:
Phylum
Class
Order
Family
Genus and
Species (which is lowest in hierarchy).
The species is the smallest unit of classification.
It is the most specific because the individuals within a species are:
Identical in appearance,Closely related and Can mate with one another to produce fertile offspring.Therefore, species are the most specific in modern taxonomy.

Explanation:
Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage.
The mutation of sickle cell anemia. Red blood cells.

A fish of genotype a/a ; B/b is crossed with a fish whose genotype is A/a ; B/b. What proportion of the progeny will be heterozygous for at least one of the genes
Answer:
Proportion of heterezygous progeny = 3/4
Explanation:
According to Mendel's law of independent assortment which states that the alleles of two (or more) different genes get sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele received for another gene.
Gametes produced by the fishes assuming independent assortment:
Fish 1 = aB, ab, aB, ab
Fish 2 = AB, Ab, aB, ab
Progeny from cross:
aBAB, aBAb, aBaB, aBab
abAB, abAb, abaB, abab
aBAB, aBAb, aBaB, aBab
abAB, abAb, abaB, abab
Proportion of heterezygous progeny = 12/16 = 3/4
How do chemoautotrophs make energy?
Answer:
Chemoautotrophs are able to synthesize their own organic molecules from the fixation of carbon dioxide. These organisms are able to produce their own source of food, or energy. The energy required for this process comes from the oxidation of inorganic molecules such as iron, sulfur or magnesium.

Which statement best describes cancer cells?
A.cells that go through mitosis successfully
B.cells that continue to replicated even when not needed and does not stop
C.cells that move to G0,the resting phase
D.cells in hypotonic, solution to burst
Answer:
B!
Explanation:
Cancer is a essentially a mistake in a cell's DNA. This is very gradual, and takes a while. The immune system deals with most of them, but some slip out of reach and continue to mutate until they grow into tumors, or large pockets of cancer cells. Since their genetic code is very messed up at this point they have no limitations on growth.
P.S. This is my first biology answer! Did I explain it good enough?
As a college student, you are no doubt concerned about the grades that you earn while completing your coursework. If you wanted to know how overall GPA is related to success in life after college, how would you choose to approach this question and what kind of resources would you need to conduct this research?
I am not a college student, I am a Freshman in High School but if I were in college this is what I would say:
In college the GPA of the student is very important and it helps a student obtain good colleges and courses in this regard.
The data collected from college alumni about their careers after college would be the required resource in this case.
What is meant by a research resource?
The kind of research one wants to do and the kind of questions in mind guide the kind of resources required for research. Currently, access to any kind of information for anyone is greater than ever before.
Thus, for good research, it's important to collect data from the right kind of resources. It needs to be located, organized, evaluated, and used for the communication of information.
Various places can be a home for a research resource or be research resources themselves. These can be traditional libraries. Whereas, personal experiences can be important research resources.
Print media, which includes journals, books, brochures, newspapers, and magazines are conventional research resources. Currently, electronic sources found on the Internet are being used. Interviews or surveys can also be considered research resources.
Therefore, to understand the impact of GPA on students' careers, we need to collect data on their careers.

Hey, do you have the answer to this question?
The atmosphere exerts a force on earth. Why does yhe atmosphere exert pressure on earth?
Answer:
The atmospheric molecules have energy because they have a quantifiable temperature. It vibrates and circulates, and bumps into other gas molecules. Most of them are elastic, which means that the molecules bounce off more than they stick together. The "bump" is a strength. It becomes pressure when applied over an area, such as your skin or earth's surface.
Explanation:
How much is the pressure of the atmosphere?
Pressures are determined by height (mostly by the volume of water vapor), temperature, and weather. The average air pressure, however, is 14.7 pounds per square inch, 29.92, or 1.01 to 105 paschal in regular conditions at the marine level. At 5 km altitude, atmospheric pressure is just about 50%. (about 3.1 miles).
Why is the Earth's surface under pressure so much higher? It's because the weight of all the air at that location really is measured. There's not much air around you to press down while you are high in the atmosphere. The whole atmosphere is heaped above you on the surface of the Earth. While the gas molecules are extremely light and distant, they are many!

Define invasive species
Answer:
An invasive species is a non-native species that spreads from the point of introduction and becomes abundant. The invasive species label attaches only to populations of species whose impact upon introduction has altered their new environment.
Explanation:
Answer:
Invasive species
Explanation:
An invasive species is an animal imported from another country. For example: the Giant African Snail. Hence their name, the Giant African Snail came from Africa. They first came into Florida as pets, and were then released into the wild. Since then, they have spread across the state. These snails eat plants voraciously, damaging crops and competing with local wildlife. They will also eat stucco, wood, and plaster, causing thousands of dollars in damage.
