A small GTP-binding protein called ______________ assembles as a ring around the neck of each deeply invaginated coated pit, pinch off the vesicle. After the budding is complete, the coat proteins are removed, and the naked vesicle can fuse with its target membrane.
Answer:
A small GTP-binding protein called dynamin assembles as a ring around the neck of each deeply invaginated coated pit, pinch off the vesicle. After the budding is complete, the coat proteins are removed, and the naked vesicle can fuse with its target membrane.
Explanation:
Dynamin - may be a GTPase that takes part in an important role in clathrin-dependent endocytosis and other vesicular trafficking processes by acting like a couple of molecular scissors for newly setup vesicles originating from the cell wall.

what are chromosomes
A. strands I'd DNA wrapped around proteins.
B. The alleles that cause certain traits.
C. Any organism that cause contains DNA
D. A form of virus that infects cells.
Answer:
A. strands I'd DNA wrapped around proteins.
Explanation:
DNA is securely packed within the nucleus by chromosomes, which are thread-like structures. Histone proteins offer structural support for DNA by coiling it around them. During cell division, chromosomes assist in the replication and distribution of DNA. Each chromosome has a centromere, which separates the p (short) and q (long) arms. The centromere is found at the constriction point of the chromosome, which may or may not be the center.

What does the term segmentation mean?
animal in which the mouth forms second in development
trait in which an animal has repeating body parts able to be specialized for different function
animal in which the mouth forms first in development
trait in which the nervous system is concentrated in one end, forming a head
Answer:
trait in which an animal has repeating body parts able to be specialized for different function
Explanation:
Segmentation is a characteristics of many living organisms. Segmentation is referred to as the division of certain body part of an organism into sections. This section is repeated as many times as possible on the animal/plant.
The segment divides the part into specialized units that performs differing functions. The different functions define the organism, hence, segmentation is very important in development.

Mrs. Tuff is now insistent that Tommy sits in her lap and as she speaks to Tommy he begins to cry more and refuses to open his mouth. Mrs. Tuff continues to tell Tommy that it won't hurt and if he only opens his mouth, he will get a toy. What steps can you take now to get Tommy to cooperate?
Solution :
Tommy is a young boy and is feeling afraid to open his mouth and show it to Mrs. Tuff. Something had stuck into his mouth and he is finding it difficult to eat anything and it is paining a lot.
Mrs. Tuff is insisting tommy to sit on her lap so that she could examine him but he refuses to open his mouth and cries loudly. I told Tommy that it is for his own good and he should listen to Mrs. Tuff and open his mouth so that Mrs. Tuff could treat him. By this Tommy will get relief from his pain and he will better.
I also insisted Tommy to open his mouth as it will cause him any pain. I gave something to Tommy so he can get distracted and open his mouth. Mrs. Tuff also told him that he will get a toy if he opens his mouth.
This is how I got Tommy to cooperate with Mrs. tuff.

The spines offer protection against predators. The population size of sea urchins is low in relation to the carrying capacity of the area. As a result, the sea urchins are Multiple choice question. A) r-strategists that allocate much energy toward parental care. By-strategists that allocate energy to producing many young. C) density-independent, because there is plenty of energy. D) irruptive, because their numbers crash quickly.
Complete question:
Sea urchins belong to the echinoderm phyla. Adult sea urchins have spines that extend outward from their exoskeleton, but as larvae, the sea urchins have only an exoskeleton made from spicules. The spines offer protection against predators. Sea urchins typically spawn near the surface. Males release sperm into floating plankton, then female urchins release between eight and 20 million eggs in the same area. The jelly-like coating on the eggs attracts the sperm, and when the two meet, they create an embryo that starts dividing into new cells within minutes.
Based on the information the population size of sea urchins is low in relation to the carrying capacity of the area. As a result, the sea urchins are
A) r-strategists that allocate much energy toward parental care.
B) r-strategists that allocate energy to producing many young.
C) density-independent because there is plenty of energy.
D) irruptive, because their numbers crash quickly.
Answer:
B) r-strategists that allocate energy to producing many young.
Explanation:
According to the given information, this species expresses survival curve type III, characteristic of r-strategists. Males and females release many gametes into the sea. If these gametes get to meet, they produce the embryo that starts developing. But there are high chances for these new organisms to die. Significant mortality during the early stages of life is expected for the species. The few individuals that manage to reach the later life stages, getting to survive, usually have a long life. These species produce many gametes to release, which results in the production of many offspring simultaneously. However, adult individuals provide no parental care. Their success in reproduction depends on the number of surviving descendants.
Males release sperm into floating plankton, Female urchins release between eight and 20 million eggs in the same area,When they meet, sperm and egg create an embryo that starts dividing into new cells within minutes.We might also mention that the population size is under the carrying capacity. r-strategist choose to live in areas with only a few individuals, where nitches are hardly occupied.

Answer:
Well to make a new gene, theoretically you would need to mutate your DNA of some sort.
Explanation:
Genes come naturally from your parents. And if you want a new gene that you can say "control" like being tall or having a high/low metabolism, you would have to rearrange or "mess around" with your DNA.

describe the structure of DNA and how it can be extracted from plant cells?
Explanation:
DNA can be extracted by grinding the tissue in dry ice or liquid nitrogen with the mortar and pestel or a food grinder. the cell membrane must be disrupted,so that the DNA is released into extraction buffer.
Plant cells are eukaryotic cells that make up plant tissues and have three types of DNA: nuclear, mitochondrial and chloroplastic, for their study, nucleic acids must be isolated by physical or chemical methods.
What are plant cells?They are eukaryotic cells that make up many of the tissues of organisms belonging to the Plantae kingdom, have a differentiated nucleus, contain hereditary genetic information (DNA) and can be nuclear, mitochondrial and chloroplastic.
The extraction and purification of nucleic acids constitutes the first stage of plant cells studies, the DNA precipitates in alcohol out of solution, where it can be seen and separates it from other cellular components, which are left in the aqueous solution.
Therefore, we can conclude that plant cells are eukaryotic cells that make up plant tissues and have three types of DNA: nuclear, mitochondrial and chloroplastic, for their study, nucleic acids must be isolated by physical or chemical methods.
