Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

how does Pteromyzon differ from scolidon and labeo fishes?
who answer this question in 10 seconds I'll mark his or her ans. as "BRAINLIST ANSWER"
It's my promise but the answer must not be copied from internet
Answer:
Due to no jaws, no paired fins and scales on the body.
Explanation:
Pteromyzon fish is different from scolidon and labeo fishes because Pteromyzon fish is not a true fish. The main reason for this is that Pteromyzon fish is agnathous means having no jaws and it doesn't have paired fins and scales on their body while all these features are present on the body of scolidon and labeo fishes so we can conclude from this discussion that Pteromyzon fish is different from scolidon and labeo fishes.

Michael loves playing his clarinet and believes it attracts more rabbits than any other instrument he
has played. In order to test his hypothesis, Michael played a song on his clarinet for a total of 5
minutes and counted the number of rabbits he saw in his front yard. He played the song a total of 3
times on his clarinet and repeated the experiment using a flute and a guitar. He also recorded the
number of rabbits he observed when he was not playing an instrument. The results are shown in the

1) What is the independent variable?
2) What is the dependent variable?
3) What is the experimental group?
4) What is the control group?
5) What is one constant from the experiment above??
Answer:
Independent variable: type of instrument
Dependent variable: Number of rabbits attracted
Experimental group: The group when he played an instrument
Control group: The group when not playing an instrument
Constant: Same song
Explanation:
1. Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, the variable that is changed is the TYPE OF INSTRUMENT used (clarinet, flute, guitar), hence, it is the independent variable.
2. Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the "NUMBER OF RABBITS ATTRACTED" by the instrument played.
3. Experimental group is the group of an experiment that receives experiment treatment, which is the independent variable. In this case, the experimental group is the GROUP IN WHICH INSTRUMENT WAS PLAYED.
4. Control group is the group that does not receive the experimental treatment. In this case, the control group is the group in which INSTRUMENT WAS NOT PLAYED.
5. Constants are those variables that remains unchanged for all groups throughout the experiment. In this case, one constant is the SAME SONG played.

Would you expect the stomata of a desert cactus or the stomata of a water lily plant to close during the day?
The stomata of a desert cactus will close during the day.
STOMATA:
The stomata (singular- stoma) are structures on the leaves of a plant that helps in gaseous exchange i.e. entry and exit of CO2 and O2 gases. The stomata, however, when opened allows the passage of water vapor from the plant. Hence, plants utilize the opening and closing of stomata to regulate water loss. Desert cactus is a xerophytic plant meaning that they can survive in low water conditions. One way they adapt to their desert environment, which is characterized by low humidity, is by the closure of their stomata during the day. Therefore, the stomata of a desert cactus will close during the day.Learn more at: https://brainly.com/question/3387375?referrer=searchResults

What causes antibiotic resistance?
- Only using antibiotics when you are also doing radiation therapy
- Only using antibiotics when you are also doing chemotherapy
- Any use of antibiotics causes resistance
- We do not know
Answer:
Antibiotic resistance occurs when bacteria change in response to the use of these medicines. Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria.

There are many different types of cells with many different types of cellular structures and functions. Which of these structures is found in all types of eukaryotic cells?
A. chloroplast
B. cell wall
C. nucleus
D. centrioles
Answer:
nucleus
Explanation:
chloroplasts and cell walls are only found in plant (and fungi) cells, while centrioles are only in animal cells.
The structure that is found in all types of eukaryotic cells is the nucleus. The correct option is C.
What are eukaryotic cells?Eukaryotic cells are those cells that contain true cell organelle. These cells are present in the higher organism, and they perform complex functions like replication, mitosis, etc.
There are two types of cells. They are prokaryotic and eukaryotic cells. Prokaryotic cells are those that do not contain an organelle and a nucleus. They are present in smaller organisms.
The nucleus is the brain of cells. It controls all functions of cells, and it contains the genetic material of the organisms. In prokaryotic cells, the nucleus is absent and in eukaryotic cells, the nucleus is present. That is the difference between them.
Thus, the correct option is C. nucleus.

On April 20, 1902, Marie and Curie with success isolate radioactive metallic element salts from the mineral uranium ore in their laboratory in Paris. In 1898, the Curies discovered the existence of the weather radium and metallic element in their analysis of pitchblende.

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:
