As the level of Carbon Dioxide in the atmosphere increases, how will (is) primary productivity impacted? How does this impact populations of primary consumers?
Answer:
Rising atmospheric carbon dioxide (CO2) and nitrogen (N) deposition increase directly the resource availability to plants, and can increase plant growth and net primary productivity (NPP; Norby et al., 2005).
Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.
Explanation:
Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.
What do you mean by Net primary productivity (NPP)?Net primary productivity may be defined as the amount of matter accumulated by plants per unit area in a given time.
Primary productivity depends on photosynthesis, where carbon dioxide gets converted to energy. If the level of Carbon Dioxide in the atmosphere increases, the photosynthesis rate increases, and finally the primary productivity increases.
Therefore, Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.

Explanation:
Hard corals have a symbiotic relationship with species of microalgae that give the corals their color and provide up to 95% of the corals' energy needs by photosynthesis. Corals get the rest of their food by consuming plankton. The microalgae are damaged by changes in water temperature 2-3C lasting five weeks or more, causing a phenomenon called coral bleaching. What will most likely be the result of increased global temperature on the diversity of hard coral species?
Question 1 options:
The hard corals will make all of their own food.
The rate of photosynthesis in hard corals will increase.
The number of different hard coral species will decrease.
The hard corals will migrate to warmer waters.
Answer:
The hard corals will make all of their own food
Explanation:
your welcome...
The most likely result with increased global temperature would be ; ( A )
The hard corals will make their own food
Given that the relationship between the corals and the microalgae is symbiotic and not parasitic therefore when the microalgae are damaged the hard corals will most likely look for an alternative food source in order to continue surviving since they do not rely 100% on the plankton for their food. which is The hard corals will be able to make their own food by capturing preys like critters.
Hence we can conclude that the most likely result with increased global temperature would be The hard corals will make their own food

a white chicken with black spots is a result of
A)incomplete dominance
B)codominance
C)simple dominant recessive pattern
D)getting bit by a cobra
Answer: A
Explanation:
Answer:
b
Explanation:
you can already get rid of d and c because you know that it has something to do with combining the 2 alleles. Incomplete dominance is when the 2 colors blend together to make another color, like a red and white flowers offspring is pink. codominance is when both alleles are shown, just like the black spots on the chicken. your answer is b!!

Auxins cause cells to grow ___. A. Longer on the sunny side of the stem. B. Shorter on the sunny side of the stem . C.shorter on the shaded side of the stem .d. Longer on the shades side of the stem
Answer:
D. Longer on the shaded side of the stem
Explanation:
Auxin is a plant hormone that promotes cell growth and elongation in plant stems.
It causes the cells to grow longer on the shaded side of the stem.
This growth allows for the plant to grow in the direction of the light source it has.
So, the correct answer is D. Longer on the shaded side of the stem

Which is true about the tundra biome?
a. It receives less direct sunlight than any other biome on earth.
b. It has more trees than any other biome on earth.
c. It can be found at low elevations all over the earth.
d. It has more types of plants and animals than any other biome on earth.
Answer:
It receives less direct sunlight than any other biome on earth.
Explanation:
The tundra biome is a cold, frozen landscape. This biome has a short growing season, followed by harsh conditions that the plants and animals in the region need special adaptations to survive. Tundra form in two distinct cold and dry regions.
The Tundra biome is a frozen landscape that has a dark and cold environment. It receives less sunlight compared to other biomes. Thus, option a is correct.
What are the characteristics of the Tundra biome?The Tundra biome is the biogeographical region that has the coldest atmosphere of all the other biomes and is marked by little precipitation, low temperatures, long winters, and short seasons for agricultural growth.
They are present in the Arctic circle as the temperature reaches below zero degrees celsius which can last up to ten months. It is mostly barren land and is majorly covered with willow trees, and birch trees. They receive very less amount of sunlight as they have a long winter season.
Therefore, Tundra receives less sunlight.

What are some ethical and philosophical questions that surround the issue of
genetic counseling? Might it sometimes be unwise to know ahead of time about
possible genetically linked disorders that might afflict your child or yourself?
Answer:
Genetic counseling raises concerns associated with confidentiality and privacy of the information. I consider that genetic information always is beneficial for the individual because this information can be used to determine the genetic predisposition of developing a particular inherited disease (and therefore prevent it).
Explanation:
Genetic counseling has historically been associated with concerns with confidentiality and privacy of genetic information. Genetic information about an individual such as carrier status (i.e., the presence of recessive deleterious alleles in the genome of the individual), his/her chance of developing a certain disease (e.g., cancer), or transmit this disease to his/her offspring is always stigmatizing, and therefore it must be kept confidential. In consequence, genetic information must be carefully handled by professionals because any filtration of this information may be harmful to the individual (for example, unscrupulous companies might use this information to select personal regarding the genetic predisposition to suffer inherited diseases). However, genetic information is very useful in order to determine the genetic predisposition of developing a particular inherited disease and thus take the necessary actions to prevent it (e.g., avoid high salt foods if there is a genetic predisposition of developing cardiovascular diseases).
Answer:
Um, I'm guessing you don't need this answer anymore seeing that it was posted last year.... but I think that it is good to know if you child has genetically linked disorders that might afflict your child or yourself so that you can be prepared before hand.

what ia arumen in ruminant animals
Answer:
Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Of the four compartments the rumen is the largest section and the main digestive centre
The rumen. The rumen (on the left side of the animal) is the largest stomach compartment and consists of several sacs. It can hold 25 gallons or more of material depending on the size of the cow. Because of its size, the rumen acts as a storage or holding vat for feed.
