Which of the following correctly identifies a lymphatic organ and describes how it
can fight cancer? (2 points)
1) Lymph vessel; removes fluid from tissues
2) Lymph trunk; returns lymph to the blood
3) Spleen; replaces damaged red blood cells
4) Thymus; exposes lymphocytes to antigens
All of the statements correctly identify a lymphatic organ. In vertebrates, the lymphatic organs, also known as the lymphoid system, are an organ system that is a part of the immune system and works in conjunction with the circulatory system.
The Lymphatic OrgansLymphatic vessels, which are found all over your body and transport lymph away from tissues, are a network of capillaries (microvessels) and a huge network of tubes.By emptying into the corresponding subclavian veins, the lymph ducts, which are formed by the lymph trunks, restore lymph to circulation.Red blood cells that are outdated or damaged are eliminated by the spleen, which also removes cellular waste from circulation.Training specific white blood cells known as T-lymphocytes or T-cells is the thymus gland's main job.Hence, all of the statements correctly identify a lymphatic organ.
How lymphatic system fights Cancer?Regional lymph nodes, which are predictive of distant organ metastases and poor survival, are accessible to tumor cells via lymphatic arteries.As the lymph fluid moves through the lymph nodes, it is filtered. B cells and T cells, two types of white blood cells, assault any viruses or bacteria they discover in the lymph.To learn more about the Lymphatic System refer to:

Explain how autotrophs need both cellular respiration and photosynthesis
Answer:
They get energy from food. Autotrophs make their own food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. And as for cellular respiration, all organisms use it to break down glucose, release its energy, and make ATP.

DNA replication is the process by which the DNA of a living organism is multiplied into two identical copies. DNA is a double-stranded molecule, hence, it must first be separated into two single strands in order to be replicated. The following are the orderly steps involved in DNA replication:An enzyme called DNA helicase unwinds DNA into single strands. A Y-shaped structure called replication fork is formed by the two single strands.DNA polymerase attaches to the primer, which is a short segment of RNA. DNA polymerase adds nucleotides to the leading strand of DNA in the 5' to 3' directionOkazaki fragments, which are small fragments of DNA are bound together by ligase enzyme and added to the lagging strand.Learn more at: https://brainly.com/question/16464230?referrer=searchResults

Explanation:
If water was removed from a plant's environment what would happen to the plant's glucose production?
Answer:
It would cease
Explanation:
If water is removed from a plant's environment, the plant's glucose product will cease. This implies that the plant will stop producing glucose.
Water is an essential ingredient for the production of glucose by plants. During the process of photosynthesis, green plants manufactures their food in the presence of sunlight. The water combines with carbon dioxide to produce glucose oxygen gas using sunlight energy. Without water, this reaction will not be possible to take place. Therefore, the production of glucose stops when there is no water.Do all rocks folow the same path through the rock cycle? Explain.
Answer:
There are three different types of rocks: sedimentary, igneous, and metamorphic. Each of these different kinds will have their own, distinct rock cycles. Thus, it's false to say that all rocks follow the same pathway.

How could one determine if two
unidentified organisms share a common
ancestor?
Answer:
Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.
Explanation:
DNA
They can look at the DNA it's the most common one.
There are 4 pieces of evolution and they are
Fossils , Geography , Embryos / DNA , Anatomy
Fossils: Physical remains of species , Determine age, location, environment
Deeper layers = older
Geography: Proves species share common ancestors, depending on where
they live
DNA: BEST evidence because it’s the MOST ACCURATE
Similarities in the early stages of development
Similarities in DNA
More similarities = closely related
More differences = not related
Anatomy: Compare body parts of different species to see how they evolved
3 different structures:
Homologous (same structure, different function)
Analogous (similar structure, different organisms)
Vestigial (body parts that no longer serve a purpose)
All of that are in evolution

What size molecules can pass through a cell membrane by a process called passive transport?
Answer:
diffusion and osmosis
Explanation:
lipid_ soluble substance
through lipid baleyer
through protein channel
Transported proteins carry small substances like water, amino acids, and charged ions. One to fifteen angstroms is the range in molecule size that can pass through the membrane. The easier it is for a molecule to move across the cell membrane, the smaller it is.
What is cell membrane ?All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
Small molecules or ions can traverse the cell membrane passively without the cell providing any energy. The three basic types of passive transport are osmosis, assisted diffusion, and diffusion.
Gases like oxygen and carbon dioxide, as well as small hydrophobic compounds, quickly traverse membranes. Water and ethanol are examples of small polar molecules that can move across membranes, though more slowly.
Thus, The easier it is for a molecule to move across the cell membrane, the smaller it is.
