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veins, the lymph ducts, which are formed by the lymph trunks, restore lymph to circulation.Red blood cells that are outdated or damaged are eliminated by the spleen, which also removes cellular waste from circulation.Training specific white blood cells known as T-lymphocytes or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:

The incidence of cystic fibrosis, a recessive genetic disorder in the Caucasian population of United States, is 1 in every 2,500 individuals. Find the number of heterozygous carriers. (p + q = 1, p2 + 2pq + q2 = 1)
Answer:
The no. of heterozygous carriers = 0.0392
Explanation:
From the given information:
The incidence of this recessive disorder i.e. q² = 1/2500
q² = 0.0004
q = 0.02
From Hardy Weinberg's Equilibrium.
p + q = 1; &
p² + 2pq + q² = 1
∴
p + 0.02 = 1
p = 1 - 0.02
p = 0.98
So, the numbers of heterozygous carrier 2pq is:
= 2 × 0.98 × 0.02
= 0.0392
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.

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.What is the role of enzymes in the DNA replication process?

According to the concept of "survival of the fittest," if a population of birds eats worms that they find deep under ground by using their beaks, birds that have longer beaks would be more likely to survive, which is present in Option B.
What is natural selection?Natural selection is a process in which the only organisms that can adapt to the environment and its changing conditions are chosen by nature, such as in the case of the Darwinian finches. when different types of birds are present in the ecosystem and all can get their favorable food source, but when an adverse climate occurs and food is only available in deep ground, only long-beaked birds can survive because they can get food. This explains the survival of the fittest by the natural selection.
Hence, as per “survival of the fittest," if a population of birds eats worms that they find deep under the ground by using their beaks, birds that have longer beaks would be more likely to survive, which is present in Option B.

What determines which bases will be brought to the DNA strand during DNA replication?
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
