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.

Hexokinase is an enzyme that catalyzes the ATP‑dependent phosphorylation of glucose to glucose‑6‑phosphate.
a. True
b. False
Answer: The statement is TRUE
Explanation:
HEXOKINASE is an enzyme that catalyzes the phosphorylation of glucose to glucose‑6‑phosphate in glycolysis. The main function of glucose is to provide energy for the tissues. The basic pathway through which energy is gotten from glucose is through GLYCOLYSIS. The glycolytic pathway is made up of enzyme catalyzed reactions that leads to the conversion of glucose to pyruvate in the presence of oxygen or lactate in the absence of oxygen.
The first step in glycolysis is catalyzed by HEXOKINASE, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose.
Therefore the above statement is TRUE.

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 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.

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.

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.

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
