4. Describe the interrelationship between cell, tissue and organ of human body.
Answer and Explanation:
Cell: Molecules get grouped in alive cellular units that have auto replication capabilities. It is the smallest structural unit capable of functioning by itself. A cell is capable of communicating with other cells, their membranes delimitate them and protect them, constituting a selectively permeable barrier, receives signals from the exterior and responds in different ways to the different signals. There are different cells with different sizes, shapes, and forms.
Tissue: A tissue is the organization and association of the same type of cells. Each tissue performs different functions. These tissues can be epithelial, adipose, nervous, muscular, and etcetera.
Organ: An organ is composed of different tissues that work together in a more complex function. Tissues form structures such as the heart, lung, kidney, brain, and etcetera. Each organ has its function.
Organ systems: When different organs get associated and work together, they become a system. Working together in a stable way organs maintain homeostasis.
Which type of molecule transfers information from the nucleus to the cytoplasm in the eukaryotic cell
Answer:
The RNA molecule transfers information from the nucleus to the cytoplasm in the eukaryotic cell through transcription and translation.
Explanation:
The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
what is the genotype of a ""normal"" male with no hemophilia a?
Answer: XHY
Explanation:
The hemophilia disease will be present in the progeny if they solely carry the Xh allele/alleles and lack the XH gene, the genotype of man is XhY.
What is hemophilia?Haemophilia was once thought of as an example of Mendelian inheritance since the disease phenotype is caused by a mutation in just one gene (F8 or F9).
But research has shown that the illness has strong genetic and phenotypic heterogeneities. The gene for either the factor VIII protein or the factor IX protein has a mutation (different from normal) in hemophilia patients.
The mutation makes the body manufacture insufficient amounts of factor VIII or factor IX.
Therefore, A normal phenotype will result from having one XH allele because this condition is recessive, the genotype of a man is XhY.

Glands that have branched ducts and secretory cells that form sacs at one end of the ducts are classified as ___________ glands.
Glands that have branched ducts and secretory cells that form sacs at one end of the ducts are called compound alveolar glands.
What is an exocrine gland?The exocrine gland secretes enzymes outside the gland through the duct. The gland can be unicellular, multicellular, compound, tubular, alveolar, etc. Their modes of functions vary too. An example of an alveolar gland is the mammary gland.

When is the kinetic energy of a pendulum the least?
Question 5 options:
On the path beginning the upwards swing.
Half the distance on the path traveling back down.
At the bottom of the swing.
At the top of the swing where it briefly stops before changing direction.
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The Correct choice is ~
" At the top of the swing where it briefly stops before changing direction "
before changing the direction, it stops for a while therefore the kinetics energy is almost zero at that particular moment ~
The answer is D - At the top of the swing where it briefly stops before changing direction. This is where potential energy is at its highest, meaning that kinetic energy is at its lowest. When the pendulum is beginning its upwards swing, it has a lot of kinetic energy. When it is half the distance traveling down it also has lots kinetic energy. When it is at the bottom it as well has a lot of kinetic energy. The only time where the kinetic energy is least is when the pendulum stops to change direction. Any form of stopping forced the object to loose its kinetic energy.
I hope this helps! :)
