In convergent evolution, unrelated species or different organisms evolve similar traits, even though they live in different parts of the world.
Answer:
True
Explanation:
Convergent evolution is a type of independent evolutionary process by which unrelated species evolve similar structural features/traits that fulfill the same or similar functions. Convergent evolution generates analogous structures, i.e., structures that have similar functions in organisms that don't share a common ancestor with such phenotypic traits. An example of convergent evolution is the wings of insects (e.g., butterflies), birds and bats. Conversely, divergent evolution is a type of evolutionary process that creates homologous structures/traits in closely related organisms because such features were inherited from a common ancestor.

Primary sensory afferent axons have widely varying diameters, and their size correlates with the type of receptor to which they are attached. Write down the axons that are the smallest and the slowest?
Answer:
Smaller and slower axons are those related to temperature, itching and pain.
Explanation:
As you may already know, the axon is an extension of the neuron that has the ability to transmit signals to cells, indicating the nerve impulse that must be felt by the body. In other words, the axons receive a synapse, which is the nerve impulse, and pass this message on to a nerve cell to turn it into a sensation. These axons have varying diameters and the speed at which they transmit messages also varies. According to researches, the smaller and slower axons are those related to the sensation of temperature, itching and pain.
Describe the structure and function of the following organelles: nucleus, endoplasmic reticulum, Golgi body, mitochondria, lysosomes, ribosomes, and centrioles
Answer: A cell organelle is defined as a cellular structure which has a specific function. The structure and function of these organelles as explained below.
Explanation:
--> NUCLEUS: This is the largest and most important cell organelle. It is enclosed by a double- layered nuclear membrane with many pores. The structure of the Nucleus makes it the 'control center' of the cell. This, it contains genetic materials( chromosomes) which controls the Production of a new cell or the whole organism itself and it controls the type and quantity of proteins( enzymes) produced in the cytoplasm.
--> ENDOPLASMIC RETICULUM(ER): this is a system of membrane-lined sacs that form channels throughout the cytoplasm. It's membrane is continuous with the nuclear membrane. There are two types of endoplasmic reticulum: rough and smooth. The rough ER packs and transports proteins made by ribosome while the smooth ER is involved in lipid and steroid synthesis.
--> GOLGI BODY: This is a stack of membrane-lined sacs. It is continuously formed at one end and broken off as bubbles or vesicles at the other end. These vesicles carry 'export materials' like enzymes and hormones which the cell makes.
--> MITOCHONDRIA: This is a sausage-shaped body surrounded by a double-membrane layer. The inner membrane is folded to form partitions which project into the inside of the mitochondria. The energy producing reactions of cellular respiration take place in the mitochondria. It is thus often called the cell's 'power- house'.
LYSOSOMES: These are small round sacs that contains digestive enzymes which break down structures and substances. They are also involved in the transport of materials in and out of the cell.
RIBOSOME: These are found on the surface of rough endoplasmic reticulum and are sites for protein synthesis of the cell.
CENTRIOLE: Two rod-like centrioles are found at right angles to each other in an animal cell. They are found near the nucleus and seem to be concerned with cell division.
What is the difference between a protein and a trait
Answer:
The Relationship Between Genes, Proteins, and Traits
A gene codes for a particular protein that is involved in the expression of a trait. Characteristics determined by single genes are called Mendelian traits.
A gene is a stretch of DNA on a chromosome that has the instructions for making a protein. Each chromosome has many genes with humans having over 22,000 genes in all. A gene's instructions for a protein are written in the three letter code I referred to before. A protein is a molecular machine that does a specific job.
Explanation:
NOT MY WORDS! I HOPE THIS HELPS!
Genes contain the information that determines traits that are characteristics or features that are given to us or inherited from parents. Each cell in the human body contains about 25,000 to 35,000 genes.
What are Genes?Genes are defined as the basic units of heredity passed from parent to child that are made up of sequences of DNA and arranged one after the other at specific locations on chromosomes in the nucleus of cells.
Genes are defined as functional units of heredity as they are made up of DNA where as chromosome is made up of DNA which contains many genes. Each gene has a special set of instructions for a particular function or protein-coding. Genes are responsible for heredity.
Thus, Genes contain the information that determines traits that are characteristics or features that are given to us or inherited from parents. Each cell in the human body contains about 25,000 to 35,000 genes.

A trait has two alleles, represented by p and q. If p = 0.89, what is q?
Answer: 0.11
Explanation:
According to the Hardy-Weinberg principle, it's stated that the sum of the two alleles must be 1.
In this case, we've been given that a trait has two alleles, represented by p and q and p is given as 0.89, then the value of P will be:
p + q = 1
q = 1 - p
q = 1 - 0.89
q = 0.11
Therefore, q is 0.11

currents are caused by temperature and density differences.
A. Surface
B. Longshore
C. Deep
D. Tsunami
Answer:
The current answer is - Deep.
Explanation:
If the water becomes denser, movement of water below the surface, and surface water is cool then Deepwater currents are formed. These currents are formed mainly due to differences in density, temperature and salinity.
These currents move towards the equator from the poles that carry cold water slowly than the surface water currents. It is due to density difference and temperature difference in the water.

What happens after metaphase?
O A. Telophase
O B. Prophase
O C. Go phase
O D. Anaphase
it's D. anaphase
hope this helps
The correct sequence of Mitosis are Interphase – Prophase – Metaphase – Anaphase – Telophase. Therefore, Anaphase happens after metaphase. So, the correct option is D.
What is Mitosis?Chromosomes that have been duplicated are split into 2 new nuclei during the cell cycle phase known as mitosis. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Hence, equational division is another name for mitosis.
A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly separated into two daughter cells with identical genomes after mitosis.
Interphase, Prophase, Metaphase, Anaphase, and Telophase are the proper phases of mitosis. Anaphase therefore follows metaphase.
Therefore, the correct option is D.

What is the difference between the rough and smooth endoplasmic reticulum?
Answer & Explanation:
The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.
