how can different cells do different jobs in the human body with the same DNA
Answer:
Almost all of the cells in your body share the same DNA as was found in that first cell*. For a cell to work, 1000's of these proteins must be made, each doing its particular job. Eyes and lungs are so different because different sets of proteins are made in the various eye and lung cells.

Explanation:
Gene expression can occur at several points along the pathway from DNA to RNA to proteins. In one example of gene expression, the protein insulin must be trimmed to a smaller size.
How is this is an example of gene expression?
A. until the protein is trimmed, it is not useful to the cell
B until the protein is trimmed, transcription is blocked by repressor protein
C. until the protein is trimmed ribosomes are not active
D. until the protein is trimmed the shape of DNA blocks transcription
Answer:
A. until the protein is trimmed, it is not useful to the cell
The trimming of protein insulin to a smaller size represents an example of gene expression until it is trimmed, it is not useful to the cell. Thus, the correct option for this question is A.
What is gene expression?Gene expression may be characterized as a type of biological process through which a gene gets turned on in a cell in order to make RNA and ultimately proteins. With the help of this process, information from a gene is used in the synthesis of a functional gene product that enables it to produce end products.
The process of gene expression consists of two major steps: transcription and translation. During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA in the cell nucleus.
While the process of translation involves the mechanism through which RNA is converted into amino acids through which functional proteins are constructed.
Therefore, the trimming of protein insulin to a smaller size represents an example of gene expression until it is trimmed, it is not useful to the cell. Thus, the correct option for this question is A.

The complete question is attached as image.
It can be structural adaptation means the physical changes that organisms undergo in order to adapt to changing environmental conditions Thickness or fur coat, beak type, tooth type, motions, and other structural modifications are examples.
All of the behavioral modifications that organisms make in order to adapt to diverse conditions/situations are referred to as behavioral adaptations. Hibernation, nocturnal nature, flocking, migration, bird cries, and other behavioral adaptations are examples.
Thus, the correct match will be structural adaptation is thickness of fur coat, type of beak, while behavioral adaptation is nocturnal nature, hibernation, and flocking.

When these sex cells combine during_____,the chromosome number of the resulting zygote will double, the same as the number found in the organisms body cells.
Answer:
sexually, 4, egg, sperm, fertilization.
Explanation:
Follow the order I put the words into the order of the blanks.
Fill in the blanks for the detailed process of meiosis as follows:
In sexually reproducing organisms, meiosis produced four daughter cells that contain half the number of chromosomes as the parent cell.In females, meiosis leads to egg cells and sperm cells in males. When these sex cells combine during fertilization, the chromosome number of the resulting zygote will double, the same as the number found in the organism's body cells. What is Meiosis?Meiosis may be defined as a type of cell division that significantly produced four daughter cells from a parental cell. These daughter cells are genetically unidentical and may contain half the number of chromosomes of the diploid parental cell.
Due to their structure and number of chromosomes, these cells are haploid in nature. Germ cells or sex cells are generally produced by this mechanism of cell division. This is because when they fertilize each other, they produce the complete number of chromosomes, ie. n + n = 2n.
Therefore, the fill-in-the-blanks for the detailed process of meiosis is well described above.

Answer:
Hello! So sorry I am late! I do not have the exact answer for this question but here is some information that may be able to help you.
Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures. Fusion of the male and females gametes forms the diploid zygote, which develops into the sporophyte.

What is the advantage of these different feeding niches for the birds?
A
less competition for food
B
fewer abiotic resources for each bird species
с
fewer biotic resources for each bird species
D
less energy available as the birds feed higher in the tree
Answer: it's D
Explanation: As more birds feed higher in the tree, available energy increases. More abiotic resources are available for each bird. Predators are less likely to feed on birds in a variety of locations.
The advantage of different feeding niches for the birds species is the less competition for the food and other resources. Thus, the correct option is A.
What is the advantage of feeding niches?Animals can occupy the same ecosystems, but will not have the same niches. The feeding habits and the other adaptations determine niche of an animal within its ecosystem. For example, cheetahs and lions have different hunting styles, thus are able to coexist in the same habitat.
If any two species can have the exact same niche, then they would be in direct competition for the resources with each other. If the competition occurs, then one species will outcompete the other species. If the losing species does not adapt to the change, this may lead to its extinction.
As more and more birds feed higher in the tree, the available energy for the species increases. More resources will be available for each bird niche.
Therefore, the correct option is A.
