different types of energy
Answer:
There are many types of energy such as chemical, heat, sound, electric and light.
Explanation:
Examples: of these are electrical coming from kinetic energy the movement of two objects moving together. Then there is chemical energy which is stored in bonds of chemical compounds, the product of chemical energy is heat.

Answer: capillaries
Explanation:
Answer:
Capillaries
Explanation: Fluid is forced out of capillaries (filtration) by blood pressure (hydrostatic pressure). As plasma is filtered, globular proteins are concentrated in the blood passing through the glomerulus, as globular proteins are too large to be filtered.
18. Brayden is trying to figure out how petal shape is determined in two different roses. In the pink
rose, the copies of the gene are the same as each other. In the yellow rose, the copies of the gene are
different from each other. How does this affect how many types of proteins there are in each petal
cell?
a
The pink rose has one type of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
b
The pink rose has one type of protein for the petal shape feature. The yellow rose has one
type of protein for the petal shape feature.
с
The pink rose has two types of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
d
It is impossible to say anything about proteins from the given information.
Answer:
c
Explanation:
they would have diffrent gene versions and protines to get their colors
In the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.
What is the petal shape dependent on?Generally, the characters are dependent on the genes that are present in the DNA; either the gene variants, such as the alleles, show pure dominance or they combine to produce the effect, and here the pink rose petal has the same alleles so they will express the single protein while the yellow has different alleles so it has the chance of the two proteins.
Hence, in the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

What’s the difference between a primary source and a secondary source?
A primary source was written by someone who actually experienced the event.
The difference is about where the source appears—online or in print.
Primary sources are shorter than secondary sources. The difference is about how closely the source relates to your topic.

Does one disease happen in the circulatory system which can affect homeostasis?
Answer:
Your circulatory system delivers oxygen-rich blood to your bones. Meanwhile, your bones are busy making new blood cells. Working together, these systems maintain internal stability and balance, otherwise known as homeostasis.

16. The substances that are reabsorbed did not diffuse (move) from the nephron bowl into the
renal vein cup. You needed to use lots of energy to make reabsorption happen. Which
process do you think the kidney uses to transport these substances from the nephron to the
renal vein-active transport or diffusion (passive transport)? Explain your answer.
Answer:
Active transport.
Explanation:
The kidney uses active transport to move these substances from the nephron to the renal vein because these substances did not moves from the nephron bowl to the renal vein through simple diffusion so for this purpose active transport is used in which energy is spent in order to move the substances from one region to another so we can say that kidney must use active transport to move reabsorbed substances from the nephron to the renal vein.
What is the history of Gene Therapy?
Answer:
The concepts of gene therapy arose initially during the 1960s and early 1970s whilst the development of genetically marked cells lines and the clarification of mechanisms of cell transformation by the papaovaviruses polyoma and SV40 was in progress.
Explanation:
Answer:
The concept of gene therapy arose during the 1960s and 1970s and is still in its infancy, meaning there is a paucity of reliable, long-term data on the safety and efficacy of this therapy.

A
Explanation:
Answer:
prophase, in prophase the mitoic spindle forms and the chromosomes condense. Prophase is the first stage before cell division (mitosis) and chromosomes will be present in the cell.

EOC Biology STAAR Test Prep
In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codiminant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes.
O only
A or B only
A, B or O only
A, B, AB, or O
Please explain, also this is not a test its a test PREP
Answer:
D. A, B, AB, or O
Explanation:
We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:
Individual 1 = AO, Individual 2 = BO
A O
B AB BO
O AO OO
Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:
A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.
Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.
Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.
Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.

plant kingdom from members of the animal kingdom?
Select one:
A. Plants store genetic information in the nucleus of their cells
B. Plants are motile primary consumers
C. Plants are multicelular
D. Plants are autotrophic
Answer:
D. Plants are autotrophic
Explanation:
Both plants and animals are eukaryotic, meaning they contain a nucleus with genetic information, so that crosses out A. I don't know what motile primary consumers are. Assuming, they're primary consumers, primary consumers are those that eat producers, so in this case, this would elminate B. Both plants and animals are multicellular. Plants ARE autotrophic, meaning they produce their own food. Animals, however, have to get their own food, either by hunting or scavaging.heeeeeeeeeeeeeeeeeelp

The following table describes some biotechnological processes.
Biotechnological Processes
Process Description
1 Producing offspring that have identical DNA as one parent
2 Crossing a high-yielding fruit variety with a high-vitamin variety
Which biotechnological processes are described in the table? (3 points)
a
Both processes describe cloning.
b
Both processes describe genetic engineering.
c
Process 1 describes cloning and process 2 describes artificial selection.
d
Process 1 describes artificial selection and process 2 describes cloning.
Answer:
c . Process 1 describes cloning and process 2 describes artificial selection.
Explanation:
Process 1 describes cloning because offspring is produced that are similar to its parent and we know that in cloning, the offspring is identical to their parents while on the other hand, process 2 describes artificial selection because crossing between a high-yielding fruit variety with a high-vitamin variety is done which is only possible through the intervention of humans.
