12. Where is the rate of primary production the lowest?
a. upwelling along coasts
b. in the middle of the current gyres
c. along the Equator
d. around Antarctica in the summer
e. coasts
Answer:
Option B, in the middle of the current gyres
Explanation:
The zones of upwelling have high productivity as they have adequate climate and weather condition along with availability of nutrients. The same is applicable for Equator and coastal regions. The productivity of Antarctica is low but not less than that of current gyres as in the middle of the current gyres there are high current streams that reduces the biological productivity.
Hence, option B is correct

how does Sexual reproduction leads to genetic variation.
Answer:
Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. ... Sexual reproduction involves meiosis, which is the process of a cell doubling its DNA, shuffling its genes, and then dividing the shuffled DNA among four cells.

Why are cetacean are smarter than primates?
Answer:
well no duh we humans we smart and we invented half the stuff in the world
Explanation:
Answer:
Evolution and different environments.
Explanation:
Primates are intelligent in their own ways, such as motor control, the use of hands and feet simultaneously, control of both hands for different things at the same time.
Dolphins for example, however, they lack the limbs that primates do, so they don't need motor control as much as primates. They evolved to be very social animals, and that allows them to excel in groups while maintaining a pattern seeking brain much like primates, without the motor control capabilities.
When a person undergoes gastric bypass surgery, can their hunger, appetite, and
satiety cues change?
Answer:
Yes
Explanation:
Yes, after an individual undergoes gastric bypass surgery many different metabolic hormones become affected by the surgery. Such hormones include Gherlin, Leptin, Gastrin, and Insulin, all of which can affect the individual's hunger, appetite, and satiety cues. This is mainly because the surgery greatly shrinks the amount of food that an individual can eat at any given time. Since it basically shrinks the stomach by creating a small pouch where food enters and goes straight into the intestinal track it gives the individual the feeling of being full with much less food.

Michelle is looking at an organism that is eukaryotic and multicellular, and it also feeds on dead and decaying organisms. Which kingdom does it belong in?
fungi
plants
bacteria
archaebacteria
protists
animals
Pls answer quick
Answer:
Fungi
Explanation:
Fungi (such as mushrooms) are eukaryotic and multicellular. They are decomposers, which means they feed on dead and decaying organisms. If the question was only asking for one that feeds on dead and decaying organisms, the answer could also be bacteria, for they are also decomposers, but bacteria are prokaryotes and unicellular.

Which organ system gives instructions to the muscular system and the circulatory system during exercise?
Answer:
Nervous system
Explanation:
The nervous system can be divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The autonomic nervous system is a part of the PNS which is concerned with the control of involuntary physiologic processes. During the exercise, the sympathetic nerves of the autonomic nervous system are in charge of preparing the body for physical activity by increasing the respiration rate, heart rate and blood pressure. The sympathetic nerves can also increase energy for the muscles by reducing insulin release and increasing blood glucose.

Answer:
B.
*Read the explanation plz
Explanation:
A actually increases sutainability, and C is just wrong. It's technically saying that we should not let humans be born, we shouldn't let people get pregnant, which of course no one is gonna listen to. So B is right because if we consume too many things, the next generation won't have as many resources as they need to survive.

Evolution occurs from simple to complex organisms i.e from anaerobic prokaryotes, unicellular photosynthetic prokaryotes unicellular eukaryotes, multicellular eukaryotes. Correct answer is option (c).
What is cell theory ?According to the cell theory,
Cells make up every living thing. They can be either unicellular or multicellular in nature.The simplest form of life is the cell.Existing cells give rise to new ones. They are not the result of spontaneous generation.Eukaryotes are thought to have developed from prokaryotes approximately 2.7 billion years ago. The main difference between these two types of creatures is that eukaryotic cells have a membrane-bound nucleus, whereas prokaryotic cells have not.
Therefore, option (C) is correct because prokaryotes are the simplest cellular organism while eukaryotes are complex multicellular.

Explain why sweat accumulates on a person's skin in a hot humid
Environment
Answer:
In humid conditions where surrounding air cannot hold further water vapour, sweat evaporates slowly, if at all. As a result the body heats up. it is difficult for the sweat to evaporate and in high humidity conditions we tend to sweat more. This explains why it feels so much hotter in high humidity.
A breeder is trying to decrease the maturation time in a population of sunflowers. In this population, the mean time to flowering is 100 days. Plants with a mean flowering time of only 90 days were used to produce the next generation. If the narrow-sense heritability for flowering time is 0.2, what will the average time to flowering be in the next generation
Answer:
The next generation average time to flowering will be 98 days.
Explanation:
Before answering the question, we need to know a few concepts.
Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations. Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced. The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,SD = Xs - X₀
Heritability in the narrow-sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.h² = R/SD
The response to selection (R) refers to the metric value gained or lost from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.R = h²SD
R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),
R = X₀ - X₁
-------------------------------------------------------------------------------------------------------------
Now that we know these concepts and how to calculate them, we can solve the proposed problem.
Available data:
trying to decrease the maturation time in a population of sunflowers.the population mean time to flower is 100 days → X₀Chosen parental Plants mean flowering time is 90 days → Xs the narrow-sense heritability for flowering time is 0.2 → h²According to what we sow previously, we need to find out the value of X₁, which reflects the next generation average time to flowering.
We know that R = X₁ - X₀, so we need to clear this formula to calculate X₁X₁ = R + X₀
We already know that X₀ = 100 days,
Now we need to calculate R.
R = h²SDWe know that h² = 0.2,
Now we need to calculate SD
SD = Xs - X₀Xs = 90 days → Parentals media flowering time
X₀ = 100 → Population media flowering time
SD = Xs - X₀
SD = 90 - 100
SD = - 10 days
Knowing this, we can calculate R
R = h²SDo h² = 0.2
o SD = - 10
R = 0.2 x (-10)
R = - 2
Finally, once we know the R-value we can calculate the X₁ valueX₁ = R + X₀
X₁ = - 2 + 100
X₁ = 98
