Explanation:
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins, as well as the introduction into the systemic circulation of various objects (small and large molecules, liquids, infectious agents, etc.), packed in delivery vehicles - exosomes and vesicles
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.
What is lipoprotein?Particles called lipoproteins are comprised of protein and fat (lipids). They deliver cholesterol to your cells through your bloodstream.
High-density lipoprotein, or "good" cholesterol, and low-density lipoprotein, or "bad" cholesterol, are the two main categories of lipoproteins.
LDL comes in the form of lipoprotein. These lipoproteins transport cholesterol to the artery cells. High levels of LDL particles can cause cholesterol to accumulate in your arteries and create blockages known as plaques. The term "hardening of the arteries" or atherosclerosis refers to this condition.
Therefore, The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.

What is the difference between El Nino and La Nina in science terms of climate?
Answer:
El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of it. El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
Hope this helps
Answer:
Well, El Niño(warmer environment) impacts weather systems around the world, while La Nina(cold environment) tends to have global climate affects opposite to El Nino.
A bat is a mammal even though it flies in air. Why?
Answer
Bats are true mammals in that they give birth to live young, produce milk to feed their young, have hair, and they are warm-blooded (they can self-regulate their body temperature). ... Bats use their wings to fly, and they often use them to catch their prey, mostly flying insects.

discribe the processes of transcriotion and translation
Explanation:
Basic Biology
BASIC BIOLOGY
Inspired by life
TRANSCRIPTION AND TRANSLATION
Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation.
Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA.
The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.
DNA → RNA → Protein
DNA and RNA are similar molecules and are both built from smaller molecules called nucleotides. Proteins are made from a sequence of amino acids rather than nucleotides. Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein.
These two processes are essential for life. They are found in all organisms – eukaryotic and prokaryotic. Converting genetic information into proteins has kept life in existence for billions of years.
DNA and RNA
RNA and DNA are very similar molecules. They are both nucleic acids (one of the four molecules of life), they are both built on a foundation of nucleotides and they both contain four nitrogenous bases that pair up.
A strand of DNA contains a chain of connecting nucleotides. Each nucleotide contains a sugar, and a nitrogenous base and a phosphate group. There is a total of four different nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).
A strand of DNA is almost always found bonded to another strand of DNA in a double helix. Two strands of DNA are bonded together by their nitrogenous bases. The bases form what are called ‘base pairs’ where adenine and thymine bond together and guanine and cytosine bond together.
Adenine and thymine are complementary bases and do not bond with the guanine and cytosine. Guanine and cytosine only bond with each other and not adenine or thymine.
There are a couple of key differences between the structure of DNA and RNA molecules. They contain different sugars. DNA has a deoxyribose sugar while RNA has a ribose sugar.

acromion of the scapula
The acromial end of the clavicle articulates with the acromion of the scapula at the acromioclavicular joint. This end is also anchored to the coracoid process of the scapula by the coracoclavicular ligament, which provides indirect support for the acromioclavicular joint.

These types of consumer relationships can affect the size of prey and plant populations in a community and determine the places these prey and plant species live. For example, certain plants only grow in steep hillside in a habitat because they are eaten near the stream in the valley, or deer live in the forest to better hide from wolves in the open fields.

Skeletal muscle exhibits alternating light and dark bands called a sarcomere
Skeletal muscle is having sarcomere having myofibrils which appear dark and light in the microscope.
What is skeletal muscle?Only thin filaments containing actin are present in isotropic bands, anisotropic bands are the darker bands (A bands).
Repeating sarcomere sections, which are visible under the microscope as alternating dark and light bands, make up myofibrils.
When a muscle contracts or relaxes, long, fibrous protein filaments called sarcomeres glide past one another. Because of this, skeletal muscle is also known as striated muscle.
Therefore in appearance due to myofibrils composed of the sarcomere look light and dark bands in the skeletal muscle under a microscope.
