One of the three lines of defense against pathogens is ________?

Although sequencing all mRNA molecules in a human blood sample provides valuable information about the expression levels of genes, it would be inadequate to identify all the human genes.

This is because mRNA molecules undergo post-transcriptional modifications, such as alternative splicing, which result in the generation of multiple mRNA isoforms from a single gene. Therefore, sequencing mRNA molecules can only identify the expressed isoforms and not all the possible isoforms that can be produced from a single gene. Additionally, some genes may not be expressed in the blood sample or may be expressed at very low levels, which would make it difficult to detect them. Furthermore, some genes may not have mRNA intermediates, such as non-coding RNAs or genes that are only transcribed but not translated into protein, and would be missed by mRNA sequencing. Therefore, to identify all the human genes, a comprehensive approach that integrates multiple omics data, including mRNA sequencing, protein sequencing, and epigenetic profiling, is needed.

A group of cells performing a specialized function is called tissue. Tissue is a group of specialized cells that function together to perform a specific function.

Tissue types are categorized based on the functions they perform and their cellular structure. The four main types of tissue are epithelial, connective, muscle, and nervous tissue. Epithelial tissue is a type of tissue that lines the surfaces and cavities of organs.

Its primary function is to protect and cover the body, as well as to absorb and secrete substances. Connective tissue is a type of tissue that supports, protects, and connects different parts of the body. Muscle tissue, on the other hand, is a type of tissue that contracts and relaxes to produce movement. Finally, nervous tissue is a type of tissue that transmits electrical signals throughout the body.

The diagram represents the first stage of embryonic development which is known as fertilization. Thus, option A is correct.

What is fertilization?

The process of fertilization is defined as the process in which two gametes fused together to form a zygote is known as fertilization. The average cycle lasts 28 days; however, cycles can last anywhere from 21 to 35 days. The menstrual cycle is triggered by the rise and fall of chemicals in your body known as hormones.

It goes through four stages: menstrual, regenerative, proliferative, and secretory. The cycle duration is the time it takes from the first day of one menstruation to the first day of the following menstruation; most usual cycles last 28 days, but it can range from 21 to 40 days.

Gametogenesis is an important process of development which deals with the division and differentiation of diploid(2n number of chromosome) precursor cell to generate haploid gamets. During gametogenesis meiotic division of diploid gametocytes occur to form haploid gamets.

Therefore, The diagram represents the first stage of embryonic development which is known as fertilization. Thus, option A is correct.

Option D is correct. Synapse is the structure which does communication between two neurons or between a neuron and a target tissue occur

A synapse is an unique junction where electrical and chemical signals are exchanged between two neurons or between a neuron and a target tissue. The electrical signal of the sending neuron is changed into a chemical signal at the synapse, where it is transmitted across the space between neurons. The electrical signal is transferred to the following neuron when the chemical signal connects to receptors on the receiving neuron.

The cell body is the substantial middle portion of a neuron and houses the nucleus as well as the majority of the organelles.

Nucleus: The nucleus houses the genetic material and serves as the control centre of the neuron.

Dendrites - A neuron's branching processes that receive messages from neighbouring neurons are known as dendrites.

The fundamental components of the nervous system are neurons. They are specialised cells that communicate with various nerve, muscle, and gland cells. A cell body, dendrites, and an axon make up a neuron. The nucleus and other organelles are found in the cell body. Short extensions of the cell body, called dendrites, receive signals from other neurons. A lengthy projection that sends signals to other neurons or muscles is called an axon. Neurotransmitters are substances that are released by neurons to communicate with one another.

In a second stage, platelets, which are normally free-floating in plasma, impact the area of ​​vessel rupture, exposing the underlying connective tissue and collagen fibers.

In a second stage Platelets begin to clump together, become sharp and sticky, and bind to the exposed collagen and endothelial layers. Collagen is the only matrix protein that supports both platelet adhesion and full activation. When collagen is exposed to flowing blood, platelets rapidly attach, spread and become activated and begin to form aggregates. Released secretory granules recruit additional platelets to form a platelet plug called primary hemostasis. After vasoconstriction, exposed collagen from the injured surface promotes platelet adhesion, activation, and aggregation to form a platelet plug that seals the injured area. The presence of VWF is required for optimal platelet adhesion to withstand the shear forces exerted on platelets by flowing blood. At the site of vascular injury, VWF present in plasma binds to collagen through its A3 domain when collagen is exposed to circulating blood.

Explanation:

Thyroxine amino acid-based hormone uses the direct gene activation method illustrated in this image.

Thyroxine also called tetraiodothyronine (T4) is a hormone produced by the thyroid gland. It plays a crucial role in regulating metabolism, growth and development in humans and other animals. Thyroxine uses the direct gene activation method to achieve its effects. This means it binds to a receptor on the cell membrane which then travels to the cell nucleus, where it activates or deactivates specific genes.

This process leads to changes in the protein production and metabolic activity of the cell. Although thyroxine is water soluble it cannot cross the cell membrane unaided.

It is therefore transported into the cell by a membrane carrier protein, which recognizes and binds to the hormone so that it can cross the cell membrane and into the cytoplasm. From there thyroxine can reach the cell nucleus and activate its target genes.
