The introduction of which factor would least affect the biodiversity of an ecosystem?
A. A new disease
B. A native species
c. An invasive species
D. A human population
Answer:
Native species
Explanation:
New diseases could cause widespread illness and even death that could drastically affect trout population. Invasive species are unnatural towards an ecosystem because predators aren't adapted to hunt feral hogs. Human population causes habitat destruction and hunting of large megafauna like buffalo and elk.
Answer:
B. Native species.
Explanation:
Being a Native species (meaning the species belongs in that ecosystem), they would have almost no affect on the biodiversity of that ecosystem. Human population, invasive species (species that DO NOT belong in an ecosystem), or a new disease could be catastrophic to the biodiversity of an ecosystem.

If a species has 35 % adenine in it’s DNA what is the percent of the other three bases
Answer:
35% thyamine, 15% guanine and 15% cytosine
Answer:
35% thymine, 15% guanine and 15% cytosine
Explanation:
35% thymine, 15% guanine, and, 15% cytosine because the exact same amount of thymine would pair up with adenine, thus thymine has to be 35%. Thymine and adenine take up 70% of the DNA the rest has to equal 30%. Guanine and cytosine make up the rest, which is 30%, thus we have to split it evenly because they pair up with each other. Therefore, guanine and cytosine equal 15%.

On the basis of Thomson’s model of an atom, explain how the atom is neutral as a
whole.
Answer:According to Thomson€™s model of the atom, an atom consists of both negatively and positively charged particles. The negatively charged particles are embedded in the positively charged sphere. Thus, by counterbalancing each other€™s effect, they make an atom neutral.
Explanation:
Answer:
As per Thomson’s model of an atom, the number of electrons (negatively charged) are equal to the number of protons (positively charged) in an atom. Hence the +ve and –ve
charges are neutralized by each other that makes atom neutral as a whole.

what is a zygote? (5 sentences)
Zygote is a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum. A zygote is the union of the sperm cell and the egg cell. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo. If it goes well, the embryo becomes a fetus.
___________ helps remove extra cholesterol from artery walls while ____________ leads to build up cholesterol on the artery walls
Answer: HDL (High density lipoprotein), LDL (Low density lipoprotein)
Explanation:
The high density lipoproteins are considered as good cholesterol as they remove the bad cholesterol or low density lipoprotein from the arteries. The LDL removed by them is transported back to the liver. This allows the supply of blood through these arteries. The low density lipoprotein when get build up in the artery walls can restrict the supply of blood through arteries. Arteriosclerosis involves the thickening and the loss of elasticity of the arterial walls which is caused by the deposition of the low density lipoprotein in the arterial walls and this leads to the formation of plaque which restricts the blood flow and may cause hypertension.
Answer:
HDL

why don't people get the smallpox vaccine anymore?
Answer:
After world health authorities declared smallpox had been eradicated from nature in 1980, Wyeth stopped making the vaccine. The U.S. Centers for Disease Control and Prevention (CDC) kept a stockpile for use in case of emergency. In 2003 this supply helped contain an outbreak of monkeypox in the United States.

4. How do markhors get the energy they need to perform their life functions?
They are able to use a chemical reaction to convert the sun's energy.
They are skilled hunters that eat small ground mammals for energy.
They are herbivores that consume grasses and plants for energy.
They are carnivores and eat large animals, such as snow leopards.
Answer:
They are herbivores that consume grasses and plants for energy.
Explanation:
As everyone knows ,markhors are herbivores , and herbivores means plant eater ( the animals that eats plants) , so it eats grass , it is not an carnivor or an omnivore , so it don't eat other annimals , of corse , animals can't use chamisy things ,right? Tip: THEY DON'T EAT MEAT.
Answer: They are herbivores that consume plants and grasses for energy.
Explanation: They are herbivores, therefore they eat plants and grasses for energy :D
Researchers use radioisotopes to study the metabolism of plants. This would then be followed by fractionation to
determine which biomolecules accumulated the radioisotopes. If a plant were exposed to 13cO2 over a long period,
where would the 13C ultimately be found?
CO2 is not stored by photosynthetic plants, so 13C would not accumulate.
O It would be found in fats/lipids, because they are used as the energy storage molecule for plants.
O All biomolecules would include 13C as a result of metabolic processes after photosynthesis.
O It would be found in carbohydrates like starch, because they are used as the energy storage molecule for plants.
Answer:
It would be found in carbohydrates like starch, because they are used as the energy storage molecule for plants.
Explanation:
The process of photosynthesis can be represented by the following chemical equation;
6CO2 + 6H2O → C6H12O6 + 6O2.
So, if the carbon atom in CO2 is labelled with 13C, the 13C will appear in the glucose which is ultimately converted to carbohydrates- the energy molecules stored in plants. A typical example of a carbohydrate is starch.
Answer:
B

what stages of the cell cycle are included in interphase
Answer:
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

The question was “What is the best solution for maintaining biodiversity?”
Answer:
Yes
Explanation:
Indeed, the best solution for maintaining biodiversity is to conserve the biodiversity of every ecosystem, since all ecosystems have benefits to humans and the earth.
Ecosystems might vary in the kind of services they render to the planet or humans in general. For example, the forest ecosystems supply humans with the necessary timber and wood for construction purposes and sequestrate carbon/produce oxygen from and to the environment respectively. Thus, the forest ecosystem plays a huge role in maintaining the air quality of the planet in addition to several other services.
The variation in the services the different ecosystems render to the human population and the planet necessitates that the biodiversity of every one of them be conserved. Prioritizing the conservation of one over the other will result in losing some of the services provided as a result of loss of biodiversity.
Alternation of generation
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"Alternation of generation"
Alternation of generations is the type of life cycle that occurs in those plant and algae in the archaeologist and the heterokontophyta that have distinct haploid sexual and diploid asexual stages.In these groups a multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs.A mature sporophyte produces haploid spores by meiosis a process which reduces the number of chromosomes to half from 2n to n.
Two haploid spores germinate and grow into a haploid gametophyte.At maturity ,the gametophyte produces gametes by mitosis which does not alter the number of chromosomes.Two gametes from different organism of the same species fuse to diploid zygote,which develop into a diploid sporophyte . This cycle from gametophyte to sporophyte in the way in which all land plant and many algae undergo sexual reproduction.
