Describe the stages of invasion up to and including the spread stage. Also, include one barrier to could make
an invasion fail and briefly describe it.
Answer:
Introduction, naturalization, colonization, and dispersal or spreading.
Explanation:
There are four main stages of invasion i.e. introduction, naturalization, colonization, and dispersal or spreading. In the first stage, the specie is introduced in the environment, in the second stage the specie adopt the environment, in the third stage the specie started growth and make colonies to increase its population and in the last stage the specie disperse in the environment through different means and spreading of that organism occur. The failing of adaptation to the environmental conditions leads to the failing of invasion of a specie.

Leigh's disease is a mitochondrially inherited disease with symptoms that include seizures, fatigue, impaired reflexes, breathing problems, and ataxia. The pedigree shows the presence of Leigh's disease in three generations. Individual 4 had two daughters and one son, and individual 6 had one daughter and two sons. Which of the individuals indicated are affected by Leigh's disease
About the question:
You will find the pedigree in the attached files
Answer:
individual 4 → Affected woman → Black circleindividual 5 → Affected woman or man → Black circle or squareindividual 7 → Healthy woman → Empty circleindividual 10 → Affected boy → Black SquareExplanation:
Mitochondrial inheritance is the transmission of a disease or a trait from the maternal line.
Most of the DNI is in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly transfer mitochondrial genes to the progeny, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this mitochondrial DNI, the whole progeny of the mutated woman will be affected, as they will get the mother genotype carrying the mutation. On the contrary, if an affected man is carrying a mutation in mitochondrial DNI, non of their descendants will get the disease.
Before answering the question, let us remember the pedigree symbols.
Squares represent Males/Men Circles represent Females/WomenEmpty symbols represent healthy/non-affected individualsSolid black symbols represent sick/affected individualsIn the exposed pedigree, we can see that the mother is affected by the disease (individual number 2), so all her children are also affected (individuals 4, 5, and 6) because the disease is mitochondrially inherited.
Individual 3 is a healthy man, so individual 4 must be an affected woman (Black circle). As she is the one affected, then all her children will also be affected. This couple had one boy and two girls. Individuals 8 and 9 are girls (circle), so individual 10 must be the affected boy (black square).
On the other hand, individual 6 is an affected man (black square), son of individuals 1 and 2. This man couples with a woman, and they have all healthy children. So this woman (individual 7) must be healthy. Even though the man is affected, all their children are not because their mother (7) is not. Remember that sperm cells do not transmit the mitochondrial genes to the progeny.
And finally, individual number 5 might be either a man or a woman. In any case, this person is also affected by Leigh's disease.

Calcium is the most abundant mineral in the human body. Calcium ions are needed for bone mineralization and tooth health,
regulation of the heart rate and strength of contraction, blood coagulation, contraction of smooth and skeletal muscle cells, and
regulation of nerve impulse conduction. When blood levels of calcium get too high, the thyroid gland is stimulated to release
calcitonin, which initiates actions to lower blood levels of calcium.
Consider the role of calcitonin. ALL BUT ONE is the result of the release of calcitonin by the thyroid gland.
A)
inhibits osteoclast activity
B)
stimulates calcium uptake by the bones
stimulates the synthesis of vitamin D
D)
decreases reabsorption of calcium by the kidneys
Answer:
decreases reabsorption of calcium by the kidneys
Explanation
from what ive found, calcitonin stops osteoclast activity, makes bones stronger, stimulates the sythesis of vitamin D, but does not (in anywhere i have read) decrease reabsorption in the kidneys. I really hope this helps.,,
if im wrong i am so sorry :(

Explanation:
Cyanobacteria can cluster together into colonies called _______, with some discovered in Western Australia that are 3.5 billion years old. Cyanobacteria produce oxygen and convert sunlight to energy using _______. Plants and arthropods didn't make the transition to land until near the end of the _______ Period. Diverse multicellular eukaryotes didn't appear until the _______ period. A large multicellular eukaryote requires more _______ to survive than a single-cell eukaryote. Respond to the following based on your reading. Describe the biological chemical processes that were responsible for producing oxygen in Earth's atmosphere, eventually leading to the Cambrian Explosion. Explain the importance of oxygen in the evolution of large multicellular animal life.
Answer:
1.) stromatolites
2.) photosynthesis
3.) Ordovician
4.) Cambrian
5.) oxygen
6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.
7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.

Which step occurs in meiosis to prepare for fertilization in sexually
reproducing organisms?
Answer: 12 sexual reproduction and meiosis concept outline
Explanation: The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually-reproducing organisms alternate between haploid and diploid stages.
Hope this helps :D
The genetic researchers at Bay Medical Company are interested in spiders with the trait for medium silk flexibility. They
think this sik can be used for medical purposes such as for making stitches and for creating artificial tendons. Why do
you think offspring B has the medium silk flexibility trait?
Answer:
Due to similar shape.
Explanation:
I think offspring B has the medium silk flexibility trait because this offspring B is identical to the spider that is responsible for medium silk flexibility trait. There are some offspring identical to male parent spider due to the presence of dominant allele whereas very littles number of offspring is similar in appearance with the female spider due to recessive allele. If the male spider has medium silk flexibility trait so more number of offspring has medium silk flexibility trait as compared to others.
The people at the Medical research bay company are researching on spiders. the trait for the medium silk flexibility. The silk can be used for medical purposes and creating other tendons.
The B offspring has the medium flexibility trait it's identical to the spider that is responsible for the medium silk flexibility trait. There are some offspring identical to male parent spider due to the presence of dominant allele spider due to recessive allele.Learn more about the medical Company are interested in spiders.

A student boiled a pot of water on the stove until there was nothing left. If he started with 100 grams of water, how many grams of water vapor did he produce?
Answer:
100 grams
Explanation:
If there is nothing left that means that all of the 100 grams have become water vapors
He produced 100 grams of water vapor in such a way that nothing was left, which means that all the water vapor of 100 grams has become.
What is Water vapor?Water vapor is also called aqueous vapor is defined as the gaseous phase of water which is a state of water within the hydrosphere. Water vapor can result from the evaporation or boiling of liquid water, or from the sublimation of ice that is transparent, as are most components of the atmosphere.
When water absorbs a sufficient amount of heat it becomes a gas known as water vapour, where the process is called evaporation. The water vapor (steam) mixes with the air and appears as water boils in a teapot and escapes into the air.
Thus, the student produced 100 grams of water vapor in such a way that nothing was left, which means that all the water vapor of 100 grams has become.
