Because no one is leaving causing the population to decrease and no one is joining cause the population to gain people.
So your answer would be A. Stable
Answer:
The correct answer for this would be A
Explanation:
This is because if the growth rate of a population is zero then it means that it's unchanging which is another word for stable.

During transcription only the "coding" strand of DNA is used. Why is it important which of
the strands is used?
Answer:
During transcription, the coding strand of DNA serves as a template for synthesis of a complementary RNA molecule. The sequence of the RNA molecule is determined by complementary-base pairing so that the RNA is a complementary transcript (copy) of the coding strand of DNA.
Explanation:
What is transcription why is it important? The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). One strand, the template strand, serves as a template for synthesis.
The coding strand contains codons, which are the nucleotide triplets which specify a unique amino acid in the polypeptide chain. These codons collectively make the genetic code, which is a universal feature in almost all the living forms on the earth. Coding strand during the transcription is shown in figure 2.
Answer:
it important because u needed to know the type of strand that are being use in dna to in order to have proper body.
Explanation:
In the embryo, the early skeletal muscle originates from the _______. In the adult, skeletal muscle is repaired by fusion of _______ with muscle fibers. Fill in the blanks.
The prenatal muscle originates from the myotome. The myotome produces presumed myoblasts that form the satellite cells. Answer: myotome / satellite cells.
How is the skeletal muscle originated and repaired?Myogenesis is the process of skeletal muscle formation during the embryonal stage. Structures derived from the mesodermal produce the firsts muscle fibers of the body, and then other additional fibers.
The myotome is a primitive muscular structure that contains progenitor muscle cells. Embryonary myotome cells produce two types of cells,
presumed myoblasts that constitute a store of cells that can multiplicate through mitosis
properly said myoblasts that can not suffer mitosis
Some of the presumed myoblasts can differentiate into other cells, and some others remain undifferentiated, turning into satellite cells.
This is, progenitor cells in the myotome originate presumed myoblasts, and then these last ones produce satellite cells located in the postnatal skeletal muscle.
Satellite cells are involved in the postnatal process of muscle repair. They suffer successive mitosis producing new myoblasts and more satellite cells.
In the embryo, the early skeletal muscle originates from the myotome. In the adult, skeletal muscle is repaired by fusion of _Satellite cells_ with muscle fibers.You can elarn more about the muscle formation and repair at

What is the function of the structure identified by the red arrow? the image shows bacteria with their nuclei in a bright blue. the red arrow points to these nuclei. genetic information mobility food capture protection
Nucleus is called as brain of the cell, which contain genetic material. The red arrow in the image is showing genetic information of the bacteria.
What is present inside the nucleus?Nucleus is generally referred as brain of the cell, it is surrounded by an envelop called as nuclear envelop.
The nucleus has a nucleolus, chromatin material and a fluid called nucleoplasm.
The chromatin material is entangled thread like structure which condense during the cell division to form chromosome.
As the red arrow is pointing towards the nuclei, it is showing the genetic information of the bacteria.
Thus the correct option is A.

Answer:
Homeostasis is the state of maintaining a stable internal environment despite changing external conditions.
Explanation:
Got it right on edge! Good luck <3
Homeostasis is defined as maintaining the internal environment without changing external conditions because the body can regulate its internal environment according to conditions.
What is homeostasis?As it is currently described, homeostasis is a self-regulating process through which biological systems retain stability while adapting to changing environments.
The maintaining of steady blood pressure in the human body by a series of tiny modifications in the normal range of operation of the hormonal, neuromuscular, and cardiovascular systems is an example of homeostasis.
Homeostasis ensures ideal conditions for enzyme functioning and all cell activities throughout the body. It is the preservation of a consistent internal environment in the face of changing internal and external situations.
Therefore to change the internal environment without external conditions, homeostasis is the major process.

D. The United States sent the first human into space and sent the first human to the moon
Answer:A
Explanation:
2. A hypothesis is an educated guess based upon observation. It is an explanation of a single event based upon what is observed. A hypothesis has not been proved but can be supported by experimentation.
a) Suppose that out of 10 trees planted in a yard, only five survived. What kind of hypothesis could you make about this observation or event? Remember that a hypothesis needs to have a certain format. (2 points)
b) How could you test this hypothesis? What type of experiment could you perform? (2 points)
c) How would this hypothesis be different from a scientific law? Review the definitions of law and hypothesis to help you. (2 points)
A law is backed by scientific evidence which is reproducible while a hypothesis is just a guess that may be confirmed or disproved by experiment.
What is a hypothesis?A hypothesis is a guess that is based on enormous background information. If only five trees survived, it is possible that they received more light than the other 5.
In that case, I will design an experiment in which the same kind of plant is randomly assigned to different treatment groups that receive varying degrees of light and the rate of growth of each group is compared.

what is meristematic tissue? write its type? give one example of each.
Meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant. When a meristematic cell divides in two, the new cell that remains in the meristem is called an initial, the other the derivative.
Meristematic cells are generally small and cuboidal with large nuclei, small vacuoles, and thin walls. A plant has four kinds of meristems: the apical meristem and three kinds of lateral—vascular cambium, cork cambium, and intercalary meristem.
There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).
Answer:
The meristem is a type of tissue found in plants. It consists of undifferentiated cells capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants. These cells continue to divide until a time when they get differentiated and then lose the ability to divide. Meristematic tissue and its types
There are three types of meristematic tissues: apical (at the tips), intercalary or basal (in the middle), and lateral (at the sides). At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone.
