Blood cells are produced in the bone marrow of the body more specifically they become blood cells from first being stem cells which then divide until they reach a mature red blood cell stage. ( or other types of cells, stem cells are like the blank template for either red blood cells, white blood cells, or platelettes.)

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.

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.

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.

Sucrose is not a simple sugar because it is made up of both glucose and fructose so sucrose is called a disaccharide. Therefore, option (D) is correct.
What is simple sugar?A monosaccharide, often known as a simple sugar, is a form of carbohydrate that cannot be broken down into smaller molecules of glucose and is thus readily absorbed by the body.
There are three primary kinds of simple sugars: glucose, fructose, and galactose. All of these sugars have the same chemical composition, but their structures are quite different from one another.
Sucrose on the other hand is a disaccharide composed of both glucose and fructose. Therefore, it is not a simple sugar and can be broken down into smaller or simpler molecules.

Name an organism where 10% of the energy that is passed on would be found?
O A. buzzard
O B. mouse
O C. fox
O d. ladybird
Does anyone knows than answer ? Help me !
Out of the organisms listed, the one that is likely to have 10% of the energy passed on is the buzzard. Therefore, option (A) is correct.
What is second law of thermodynamics?In an ecosystem, only about 10% of the energy available at one trophic level is passed on to the next trophic level. This is due to the second law of thermodynamics, which states that energy is lost as it moves through a system.
Out of the organisms listed, the one that is likely to have 10% of the energy passed on is the buzzard (option A). Buzzards are predators that feed on a variety of small animals, including mice, foxes, and ladybirds. As a result, they occupy a higher trophic level in the food chain and receive only a small fraction of the energy that is available at lower trophic levels.

12. Given the human pedigree to the right, is the trait indicated by
the darkened shapes a dominant or a recessive trait? How can
you tell?
Answer:
Darkened shapes are recessive
Explanation:
In the pedigree shown, we can see that 2 parents that are unshaded shapes have 2 children that are shaded shapes. This would be impossible if shaded shapes were dominant and unshaded shapes were recessive. This is because parents that have a recessive trait have 2 of the same alleles. So if 2 parents that both have a recessive trait have a child, the child will definitely have that trait. But we can see that this is not the case, the parents have 2 offspring that have different phenotype from the parents. This must mean the parents are heterozygous, meaning that they both have 2 alleles that are different. The dominant allele masks the recessive allele, so the dominant allele is expressed. In this case, the children inherited 2 recessive alleles, 1 from each parent, making them have a different phenotype from the parents.

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.

Insulin is an example of a toxin that can be a useful in the prescribed amount, but deadly if an overdose is taken.
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
