A sudden increase in the amount
of available nutrients can create
problems for an aquatic
ecosystem. How?
A. Large numbers of producers can confuse
herbivores.
B. Increased nutrients can cause producers to
compete aggressively with one another.
C. There is not enough oxygen in the
atmosphere to support excessive numbers of
aquatic plants.
Answer:
C
Explanation:
There would be a high amount of nitrates and phosphates, which reduces the amoubt of oxygeb in the tank, that will lead to the difficulty of supportibg the excessive amount of aquatic plants.
Answer:
C. There is not enough oxygen in the
atmosphere to support excessive numbers of
aquatic plants.
Explanation:
n excess amounts, both nutrients can cause an increase in aquatic plant growth and algae blooms, called eutrophication. These algae blooms live at the water surface, in order to easily access oxygen and sunlight. As a result, eutrophication prevents lower water levels from access to sunlight and oxygen in the air.

What organelle would you not find in a plant cell? Chloroplasts,centrioles,central vacuole,or cell wall?
Answer:
Centrioles
Explanation:
If we look at ths other options Chloroplast and Cell Wall are both needed for a plant to survive and function. So we automatically know that it's going to be there so those aren't an option. We know that both animal and plant cells have a vacuole but plant cells have larger ones so we know that's not an answer. Leaving us with the only other possible answer left, Centrioles.
Answer:
Hey!
Your answer is CENTRIOLES
Explanation:
We know that Plants have a CELL WALL (shape), a CENTRAL VACUOLE (water storage etc) and CHLOROPLASTS (photosynthesis)
BUT Centrioles don't form parts of the "components" of the plant cell...

Explanation:
The trp operon encodes the genes required to synthesize tryptophan. This operon is regulated by a feedback loop in which tryptophan binds to a transcriptional regulator leading to a change in gene expression from the operon. This is most likely an example of__________. a. inducible gene expression b. repressible gene expression c. constitutive gene expression d. post-translational regulation of gene expression
Answer:
The correct answer is option b. "repressible gene expression".
Explanation:
The trp operon is a classic example of a repressible gene expression. The trp operon controls the biosynthesis of tryptophan from an initial precursor by encoding five genes that translate to three enzymes. These enzymes act as regulators and tryptophan itself acts as the final regulator. Tryptophan inhibits its own production when it binds to the transcription regulator, therefore it is an example of a repressible gene expression.
What roles do species play in ecosystems?
There are some species in every ecosystem that are necessary for the other species in the system to survive. The ecosystem may not be able to continue functioning without the keystone species, which could be a small plant or a large predator.
What are keystone species ?
Scientists may argue over which organisms or plants in a given ecosystem should be called a keystone species because a keystone species does not have a formal name. The idea, according to some wildlife scientists, oversimplifies the role of a single animal or plant in intricate food webs and habitats. On the other hand, referring to a specific plant or animal as a "keystone species" in an ecosystem is one way to educate the general public about how crucial one species can be to the continued existence of numerous others.There are three sorts of cornerstone species referred to by numerous researchers: mutualists, ecosystem engineers, and predatorsThe "keystone" is regarded as one of the most crucial components in any community or arrangement. An organism that contributes to the stability of the system is known as a keystone species in any kind of ecosystem, including marine ecosystems. Ecosystems would look very different without its keystone species. If their keystone species vanished, some ecosystems might not be able to adjust to changes in the environment. That could result in the ecosystem's demise or it could allow an invasive species to take control and significantly alter the ecosystem's course.To know more about keystone species check this:

Which of the following is NOT one of the potential mechanisms allowing kin recognition among animals? Group of answer choices kin-differential spatial association, so that kin are reliably found in a given place phenotype matching, whereby kin are identified through comparison of their phenotypic attributes with those learned from reliable kin, including oneself kin-differential familiarization, whereb social familiars are treated as relatives. kin-branding, whereby all individuals are labeled actively by each other at birth so that kin can be discriminated from nonkin. genetic similarity detection, whereby phenotypic labels are correlated with one's underlying genotype, allowing for kin discrimination based on that.
Answer:
The correct answer is "kin-branding, whereby all individuals are labeled actively by each other at birth so that kin can be discriminated from nonkin".
Explanation:
Kin recognition, also known as kin detection, is an ability developed by some animals to detect organisms that are genetic related and discriminate among other animals that are not (nonkin). There are some mechanisms that animals use for kin recognition, however labeling actively each other is not one of them. In most cases, animals use kin recognition based on pheromonal cues.

Use the internet to research genes and their affects on heredity. How many chromosomes do we inherit from each parent? What are recessive and dominant genes? What are inherited traits? What are acquired traits?
Answer:
23 chromosomes
A dominant gene is a type of gene which dominates in the inheritance pattern and masks the other one, on the other hand, a recessive gene is that which does not show its trait in inheritance pattern and hidden by the dominant one. A dominant gene is stronger gene while the recessive gene is a week gene. Dominant gene is always expressed in the upper case letters like A, F, V whereas recessive gene is always denoted by the lower case letters like a, f and v. dominant gene show in the inheritance when one of the two genes is dominant but in case of recessive gene both the genes of a trait should be recessive.
Traits you get from your parents. Inherited features evolve due to genetic material rearrangement and mutation. The parents transfer those traits (inherited) to their offspring. These aren't dying but passed on to the next generation. Example: earlobe attached or free, and curly hair.
An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics. They are not passed on to offspring through reproduction.

If conducted accurately identical investigations should produce similar results. Sometimes, errors like measurement errors, can
cause differences in results
Sandra and Jeremy are neighbors who tested different brands of seeds in their gardens for six weeks. They grew identical gardens
in their yards and recorded results. Each of them tried three brands of pea plant seeds and recorded the plants' heights at the end
of each week. They discovered Jeremy's plants were much taller on average than Sandra's plants every week.
Which statement describes a measurement error that may have caused such a significant difference in their results?
Sandra recorded her measurements in centimeters, while Jeremy recorded
his measurements in inches.
They both took measurements on Fridays, but Sandra took hers at 4:00 PM
and Jeremy took his at 5:00 PM
Sandra used a measuring tape to collect data, while Jeremy used a wooden
tuler to take his measurements

D
Sandra measured her plants from the ground while Jeremy measured his
plants from the ends of their roots
Answer:
D Sandra measured her plants from the ground, while Jeremy measured his plants from the ends of their roots.
Explanation:
The statement that describes a measurement error is Sandra measured her plants from the ground while Jeremy measured his plants from the ends of their roots.
What do you mean by Seeds?Seeds may be defined as the unit of reproduction of a flowering plant, capable of developing into another such plant.
Three brands of pea plants are grown in the field of equal dimension, still, there may be a difference in their height that must be identified. This is surely due to a measurement mistake.
Therefore, it is well described above.

The energy used in photosynthesis come from what??
Answer:
chloroplasts.
Explanation:
Chloroplast
Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, much amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in unicellular algae, up to 100 in plants like Arabidopsis and wheat.

13. Galapagos finches are birds that live on islands
off the coast of South America. The finches on the
various islands are very different from each other.
As a result of the different food resources on the
islands, which of the following structures of the
Galapagos finches experienced the greatest
change through natural selection?
(5 Points)
Head size
Eye shape
Feather color
Beak shape
Galapagos finches experienced the greatest change through natural selection in the beak shape. The correct option is D.
What is natural selection?Natural selection is the variation in individual survival and procreation brought on by phenotypic variances.
The evolution of a population's heritable features across generations is a fundamental mechanism of evolution.
Short beaks of Darwin's finches proved to be an adaptation that rendered them better adapted to grub-eating and poking holes in the ground.
However, Darwin's theory of natural selection was strengthened by Galapagos finches.
Until they all split off to become separate species, Darwin's Finches' advantageous characteristics were chosen for over many generations. These birds possessed distinct beaks, although being almost identical to mainland finches in all other respects.
Thus, the correct option is D.

Describe how skin pigmentation is determined, and also
how it is affected by exposure to the sun.
Answer:
pigmentation is determined by the amount of melanin in the skin. Without melanin, the skin would be pale white with shades of pink caused by blood flow through the skin. The extra melanin makes your skin look darker or sun-tanned. In some cases, the sun causes an uneven increase in melanin production, which produces irregular coloring of the skin. The sun can also cause a permanent stretching of small blood vessels, giving your skin a mottled, reddish appearance.
