An ecosystem is a region where a bubble of life is created by plants, animals, and other species interacting with the weather, environment, and other factors,is defined by ecologists,
Ecosystems are made up of both biotic, or living, and abiotic, or nonliving, components. Plants, animals, and other species are biotic factors.An ecosystem's productivity, or how much is produced and how quickly it returns, as well as its biomass or the total weight of living things in the ecosystem can all be used to measure it. Of course, all these parameters matter to neighboring ecosystems as well because if one ecosystem is highly productive, the ones next door will benefit.

Answer:
1a. To collect and remove waste materials from the body.
2c. Urinary bladder.
3d. Urea
4c. Remove urea and excess water.
Explanation:
The main function of our excretory system is to collect and remove waste materials from our body because these waste materials are toxic and cause damaged our body. Urinary bladder is the organ that stores urine. Urea is present in the urine under normal conditions of the body which is waste material produced our body. The main function of kidney is to remove urea and excess water from our body.
The routes nerve impulses from our senses.
A. thalamus
B. hippocampus
C. brain stem
D. corpus callosum
Answer:
a
Explanation:
The correct answer is C. Brain Stem.
How does the brain stem function?The thalamus and other areas of the brain receive nerve signals from our senses through the brain stem. It is made up of the medulla, pons, and midbrain and is situated at the base of the brain.
The brain stem is in charge of regulating life-sustaining processes including breathing, heart rate, and blood pressure. It is also in charge of transmitting sensory data from the body to the thalamus, which subsequently transmits the data to the relevant parts of the brain.
Although the brain stem is the main pathway for nerve impulses from our senses, the hippocampus, corpus callosum, and thalamus are all important in the processing of sensory information.

what is combination reaction?
COMBINATION REACTION:
Combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions are represented by equations of the following form: X + Y → XY. The combination of two or more elements to form one compound is called combination reaction
An example could be lithium reacting with sulfur to give lithium sulfide. When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide.

Explain the difference between the three types of selection
Th difference between the three type of selection has been that stabilization selection keeps allele frequency constant, direction selection changes the allele frequency over generation, while disruptive selection maintain high allele frequency.
What is natural selection ?
Natural selection is the process by which populations of organisms adapt and change.
The 3 Types of Natural Selection
Stabilizing SelectionDirectional SelectionDisruptive SelectionStabilizing SelectionStabilizing selection is natural selection that keeps allele frequencies relatively constant from generation to generation. In other words, unless the environment changes, things stay the same.
A classic example of stabilizing selection is human birth weight Very low birth weight and very high birth weight are mutually selected to keep the mean birth weight
Directional SelectionDirectional selection is a natural selection that causes gradual changes in allele frequencies over several generations. This usually occurs when environmental/selection pressures change or when favorable new alleles emerge within the population.
Example: Recent findings show that climate change is affecting fish size in certain habitats.
Disruptive SelectionDestructive selection is natural selection that maintains high frequencies of two different allele sets. In other words, individuals with intermediate phenotypes or alleles are selected.
Destructive selection causes polymorphism: the persistence of two or more distinct phenotypes in species . This can occur in environments that exhibit variability.
For example, birds in the Galapagos Islands use their beaks to forage seeds of various sizes.
Therefore, the difference between the three types of natural selection is that:
Stabilizing selection keeps allele frequencies relatively constant from generation to generation.
Directional selection causes gradual changes in allele frequencies over several generations.
Destructive selection maintains high frequencies of two different allele sets.

Explanation:
In this metabolic process, the enzyme RNA polymerase binds RNA nucleotides (the substrates) together by catalyzing the formation of a bond between the backbone sugar of one nucleotide to the backbone phosphate of another nucleotide. Name the metabolic process that bonds RNA nucleotides together
Answer:
TRANSCRIPTION
Explanation:
Transcription is the first process that occurs in the expression of a gene. It involves the synthesis of a mRNA molecule from a DNA template. The DNA molecule, which is located in the nucleus of an eukaryotic cell, is bound to by an enzyme called RNA polymerase in order to synthesize an mRNA molecule/strand.
RNA polymerase synthesizes a mRNA molecule using complementary base pairing rule i.e. Uracil base (U) is synthesized when Adenine (A) is read, Adenine when Thymine (T) is read, Guanine (G) when cytosine (C) is read, Cytosine when guanine is read. These nucleotide bases are then joined together via chemical bonding.
In a nutshell, RNA polymerase catalyzes the formation of a bond between the backbone sugar of one nucleotide base to the backbone phosphate of another nucleotide base in the metabolic process of TRANSCRIPTION.
A cell is placed in a hypertonic solution. Which will most likely occur as homeostasis is maintained in the cell?
A.
The cell will gain ATP molecules.
B.
The cell will gain water.
C.
The cell will lose water.
D.
The cell will lose sodium ions.
Answer:
B the cell will lose water
Explanation:
Because of the hypertonic solution water will move on the concentration gradient leaving the cell and entering the solution. Thus the cell looses water.
When a cell is placed in a hypertonic solution, it will most likely lose water (Option C) as homeostasis is maintained in the cell.
What is homeostasis?Homeostasis is the ability of an organism or a system to maintain a relatively stable internal environment, despite changes in external conditions. It is a key aspect of biology that helps living organisms survive in their environment. Homeostasis is maintained through a series of physiological processes that regulate different aspects of an organism's biology, such as temperature, fluid balance, and pH
A hypertonic solution is one that has a higher concentration of solutes (e.g. salts) outside the cell compared to inside the cell. This creates an osmotic pressure gradient, which draws water out of the cell and into the solution in an attempt to balance the concentration of solutes on both sides of the cell membrane. As a result, the cell will shrink and lose water.

Which answer choice accurately depicts the sequence by which blood moves from the pulmonary vein to the body tissues?
Answer:
See the answer below
Explanation:
Oxygen-rich blood flows from the lung through the pulmonary vein to the left atrium of the heart. From there, the blood is pumped through the mitral valve to the left ventricle. The contraction of the left side of the heart sends the oxygenated blood out of the left ventricle through the aortic arch to the major arteries designated to carry blood to the major parts of the body. From the arteries, blood moves to the capillaries and then to the various tissues of the body before returning back to the heart through the vein.
Thus, the sequence of flow of blood from the pulmonary vein to the body tissues can be summarized as:
Pulmonary vein -> Left atrium -> Arteries -> Capillaries -> tissues
Explain how an animal grows?
Answer:
big liitle fat
Explanation:
Answer:
The primary way that animals grow and develop is by building more cells. When an animal eats food, its body breaks the food down and uses it to fuel its energy requirements and build new cells through the process of mitosis. These new, or daughter, cells are often similar in size to the old, or parent, cells.
