1. Gradualism
2. evolution
Answer:1.Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in a slow and consistent process of change in the whole population.
2.Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).
Explanation:
State the function of Bowman's capsule and glomerulus.
➜ Bowman's capsule and glomerulus have semipermeable walls.
The glomerulus, is a tuft of capillaries contained in Bowman's capsule.The water and dissolved substances (wastes and useful) are filtered into the Bowman's capsule and from here they are filtered into the tubule.Thus, both the structures act as filtering apparatus.Jackie Robinson avoided serious

what happens when there is a decrease in carbon dioxide during gas exchange in the body?
Answer:
Increased carbon dioxide means increased blood acidity, while decreased carbon dioxide means increased blood acidity.
The bicarbonate reaction is reversible, which allows bicarbonate to turn back into dissolved carbon dioxide to diffuse from the alveolus.

Describe fertilisation in terms of cellular and intracellular changes. I will be very happy if someone answer this I will give them brainly and likes
Answer:
during this process the nucleic of the male and female gametes are fused in order to create a zygote .known as fertilisation.Gametes contain half the number of chromosomes of all other cells in the organism .Meaning they are haploid .
Cells responsible for fertilisation:
fertilisation is the fusion of the nucleus of a male gamete with the nucleus of a female gamete ,producing a new cell called a zygote

are all cells going through the cell cycle at the same speed? why or why not?
Answer: Not all cells move through the cell cycle at the same rate. Proteins that regulate the timing of the cell cycle. Most of the differences in cell cycle duration between species and cells are found in the duration of specific cell cycle phases. DNA replication, for example, generally proceeds faster the simpler the organisms.

4) Complete the statement below showing the relationship between chromosomes,
genes and DNA.
Histone proteins form the chromosomes when the DNA is inserted into the active sites of the proteins.
Which of the choices below would determine if a protein will perform a specific function for the cell?
A.The monosaccharides that make up the protein
B. The nucleic acids that make up the protein
C. The shape of the protein
D. The fatty acids that make up the protein
Answer: C
Explanation:
The folding of the protein determines the structure. Each polypeptide has a primary structure all the way up to quartenary structure which allows the protein to fold based on the R groups of the amino acids. If the structure of the protein is disturbed, it won't perform its proper function.

C. Lymphatic system
D. Immune system
Answer:
The answer is B. Endocrine system.
Answer:
B. Endocrine system
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction.

What is cellular respiration? Use complete sentences to explain how the mass of carbon is conserved during cellular respiration. (10 points)
Answer:
Please give me brainlist.
Explanation:
Cellular respiration is a chemical process which breaks downs a 6 carbons compound into 3 carbon dioxide molecules and water molecules in the presence of oxygen and produces a huge amount of energy in form of ATPs.
Cellular respiration is a chemical process which breaks downs a 6 carbons compound into 3 carbon dioxide molecules and water molecules in the presence of oxygen and produces a huge amount of energy in form of ATPs.
What is Cellular respiration?In the presence of oxygen, cellular respiration is a chemical process that converts a substance with six carbons into three carbon dioxide and water molecules and enormous amounts of energy in the form of ATPs.
Simply put, cellular respiration is a sequence of metabolic processes that happen inside a cell. For usage in the energy-demanding processes of the cell, biochemical energy is extracted from organic materials.
It is stored in energy-carrying biomolecules (such as adenosine triphosphate or ATP).
Therefore, Cellular respiration is a chemical process which breaks downs a 6 carbons compound into 3 carbon dioxide molecules and water molecules in the presence of oxygen and produces a huge amount of energy in form of ATPs.
