Describe what lymph is and how it travels throughout the body. What would happen if the lymphatic system did not drain interstitial fluid from the body?
Answer:
A fluid that flows through the lymphatic system is called lymph. it travels when you breathe and move your muscles the lymph continuously get pushed towards the heart from the outer reaches of your body. if the lymphatic system didn't drain interstitial fluid then the lymph fluid would build up in the body's tissues, making them swell.
Two offspring from same parents can have different phenotypes. How is this possible?
Answer:
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
Explanation:
Overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.
What is heterozygote?Heterozygote is defined as a person, animal, or other thing possessing a pair of different alleles of a specific gene, one of which is dominant and the other recessive. One normal allele and one mutated allele, or two distinct mutated alleles, can make up a heterozygous genotype.
The explanation is connected to the fact that each parent has two different gene pools. Furthermore, only 50 percent of each parent's DNA is transferred to their offspring. and that the portion that is passed down is random. Every child has a unique set of genes thanks to the interaction of all these influences.
Thus, overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.

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.

Explanation:
A _______________ from the sun hits chlorophyll and excites an electron, known as __________________________________.
Answer:
Photon, light dependent reaction of photosynthesis
Explanation:
Photosynthesis is the process by which green plants make their own food in the presence of sunlight and water.
There are two steps of Photosynthesis that include light dependent reaction and light-independent reaction.
In light dependent reaction, a photon from the sun is absorbed by the green pigment in leaves called chlorophyll that allow the electron to excite from ground energy level to high energy level. It converts the solar energy into chemical energy and called light dependent reaction of photosynthesis.
Hence, the correct answer is "Photon, light dependent reaction of photosynthesis".

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.

A.
Permineralization occurs when pore spaces in an organism's remains are filled with minerals that precipitate out of solution.
B.
Petrification occurs when once-living tissues are replaced by minerals, preserving the organism's structure.
C.
Both A and B describe errors in the statement.
D.
Nothing, this statement is correct as is.
Answer:
C. Both A and B describe errors in the statement.
Explanation:
In fossilization i.e formation of fossils, two terms are used as follows: permineralization and petrification.
- Permineralization is a process whereby the pore spaces of an organism's remains are filled with mineral matter that precipitates from lake and ocean solutions.
- On the contrary, petrifaction or petrification is the process whereby a once-living tissue (matter) are REPLACED by minerals, hence, preserving the organism's structure by turning it into a stone (petros).
According to this question, the student mixed up their definitions by giving the definition of permineralization instead, however, options A and B have described the errors associated with the statement.

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:

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
